You actually can measure (or monitor) how much power is being drawn through the MagSafe port or any other charging port internally.
To do so, do the following:
1- Hold Option and click on the Apple logo on the top left of your screen.
2- Select "System Informations"
3- Choose "Power" from the left sidebar (the same place you check your battery cycle count and health)
4- Scroll down to where you can see the power Wattage, the MacBook is drawing from the adapter.
Hope you find this helpful!
đ
TIL you can option click on the Apple Logo.
I use AlDente Pro (version 1.24), and it has a very nice popup which shows up much power is being drawn from the adapter when it is plugged in, and how much of that power is going to recharge the battery, and how much is going to power the CPU. If the Macbook is not connected to power, it will show much power is being drained from the battery. So it's quite nice for showing much power you are using, and how much is getting drained from the battery.
so many people praise magsafe but don't use it. of course they're going to drive Apple to remove it yet again. fwiw, i use it exclusively.
even when you connect your mac to a monitor at home/work via usb-c which also charges it, so you connect both usb-c and (redundant in this case) mag-safe?
There is only 1 reason why I use MagSafe almost every time. I want my USB-C ports free for my SSD, and Sidecar display, and sometimes for a Mic and Camera as well. I use an M2 MacBook Air and there are only 2 ports. MagSafe is also a more satisfying way to charge your MacBook because of how easy it is to attach the cable and the indicator lights that tell you when to unplug in case you leave the lid closed.
I have a second monitor that has 60W power delivery and always thought to myself that it is quite low, and sometimes I saw battery dips when I was doing demanding tasks for CPU+GPU like you said. I wanted to switch to magsafe for this very reason but I did not know that the Mac switches to MagSafe when you connect two power supplies. Thank you for testing it!
I own the M1 Max for over a year (bought at the release). I always used MagSafe. Never charged it differently. My battery also shows 87%. What I've noticed with mine - is a few things that weren't optimized and caused CPU temp rise close to 100 degrees. Since then I've started using TG Pro with settings that turn my fans when temps rise above 70 degrees and I think it helps the battery and the laptop is just slightly louder (only during heavy-duty tasks)
Are those 70 degrees Celsius or Fahrenheit?
@@m1ar1vin As most of the world after 1960 I use Celsius ;)
@@TomaszBzymek Thank you, just making sure ;)
You can use your USBC power meter with magsafe by plugging it into the power brick end.
You can also use coconut battery to see how much power your macbook is taking over time, wether it's coming from battery or not too.
from what I understand of MagSafe 3, it's just a proprietary implementation on USB PD, so there wouldn't be any difference between that and using the thunderbolt ports.
Great video. Loved the included input/suggestions from others. All good solid thoughts. Canât wait for results about Magsafe. I have using usbc for convenience
Thanks for the tip. I've been mostly charging my M2 MBA using thunderbolt out of convenience. Just to be on the safe side I'm going to use magsafe more often, even if this problem turns out to apply to the high powered MBAs only.
I donât think it will cause any problems on a mba due to its lower power processor. Just make sure you are using a certified brick for the charging and none of the cheap crap you find out there.
I think the condition he is describing is only applicable to the 16-inch MacBook Pros which can be charged up to 140W. For all other models, USB-C can still charge the machines at full speed as long as your cable and power adapter allows it.
Ive only been using magsafe on my M1 max from april 2022 and its at 93% health, and Im using it heavy every day. It sits mostly on my desk connected to magsafe, and something like 2 times a week its on the road with me for meetings. I have it connected to a 4k monitor through HDMI which changes signal into displayport for 4k 60hz on my monitor (older 40 inch 4k monitor). Not sure how many hours i get now, but I can say in full speed mode, I can work a full day in the office without plugging it in and still have 20-30% left when I get home. For me its vscode, chrome and simulator that eats most battery.
Another thing to consider is the size of your machine. If I am not mistaken, the 14â can use the fast charge either way (thunderbolt or MagSafe), on the 16â it doesnât happen. Only MagSafe get the full wall brick output.
Hey Alex! Blender just dropped Blender 3.5 where the viewport is updated from OpenGL to Metal and Blender claims a big jump in performance. I would love to see you test in your macbook and mac studio and maybe compare the difference between performance of Blender 3.4 and 3.5.
Love your videos btw!
Thanks!
thanks for the heads up
@@AZisk Cool!
@@karthikeyanparasuraman9337 BTW, is there a demo blender project I can just download and run/render that would demonstrate the difference?

Awesome content as always đđ»
Appreciate it!
I have been using a 10C M1 Pro for 13 months, and the battery is now at 87%.
I usually just hit the CPU really hard during my workflow, and I am also using an OWC TB dock with 60W to charge it.
I also noticed the battery drain with VS Code and Skype, usually when I am not working on development( using vs code ) or joining long meeting battery lasts much longer. But in recent times VS code drain seemed to have increased quite a bit, I tried reinstalling it recently but I do not notice any improvements.
Hey Alex, I've been following your content for a while now, and I absolutely love it! Your videos are always so informative and helpful. I've been thinking, it would be fantastic if you could create a comprehensive guide on using MacBooks. From simple tasks like closing the lid and charging to more advanced features, your expertise would definitely help a lot of people get the most out of their MacBooks. Looking forward to seeing more amazing content from you!
You can measure how much energy magsafe is giving in by putting that measuring device on other side of magsafe cable (between cable and brick).
nice idea!
Or just using standard power outlet power meter, power drawn should be close to power output (some losses will occur obvs).
So can you measure please:)?
Or just install Coconut Battery. You can see how many watts are either being charged or being used based on if you're plugged in or not.
@@SIRybka yeah, I'm surprised he doesn't use battery/power tracking apps already.
Awesome info, exactly what I was looking for. Ive been curious about how reliable (or potentially dangerous) charging through thunderbolt was. The magsafe charger's cables have been notoriously flimsy and Id love to eke out as much longevity from them as much as I can. I was thinking of leaving my magsafe charger exclusively for home use, and then a usb-c/thunderbolt cable on a powerbank when using away from home. Would it be safer to use the thunderbolt port for charging while the macbook is *not* in use?
Hey Alex. AS usual a great video. I was wondering what mic you used for this video. Many thanks in advance
1:49 Is that the icon for the VS Code nightly edition? That might explain why it has leaks or issues.
Not sure if the theory holds. I use my M1 Max MBP almost exclusively via USB C, most of the time with a 60W charger, sometimes with a 100W charger and rarely with the 140W Apple Charger via Magsafe. High Power Mode as well. 16 Cycles, 98% Max Capacity according to Coconut Battery. The computer is 12 months old.
Hey Alex! Quick question: Does Ventura 13.3 BLAS and LAPACK improve execution on mac's?
I think you could measure MagSafe plugging that device directly to the charger and then plug the MagSafe cable to the output of the device?
I had the exact same problem with Settings Sync on my M1 MBP. The laptop was hot from doing... Nothing. I just removed the plugin altogether as it's deprecated
Do you think (on a 14'MBP m3) that does make any difference in speed to charge with 96w or 140w adapter? using Magsafe (and the usb c 240w cable) ?
Perhaps MagSafe is prefered (when multiple power sources connected) just because it's a dedicated port for charging, and there's likely a dedicated charger on the other end. It's a simple decision that may avoid:
- Pulling power from a connected USB-C device that has a battery
- Charging from a hub/monitor that *may* not provide all the juice it needs and is also trasmitting data
- Just charging from an underpowered source when the user clearly made sure to give it dedicated one
I think that as long as it's getting the power it needs from USB-C, it's fine.
Anecdotally, I powered my 14" with the 87W brick (it comes with a 96W) from my old MacBook for a couple of weeks. Didn't do much heavy lifting but I actually have a couple of pretty hungry devices (custom hardware for work) that feed from my MacBook's USB-C ports, and it was fine. I eventually swapped the charger, just to be sure, but it still goes through a USB-C hub.
Lucky I am, was keep using MacSafe to charge my M1 Max since it launched as I donât own a USB-C monitor. Do let us know once u measured and found how much the power from MacSafe with your inline usb-C meter. Great content as always Alex đđ»
Hey Alex, which tool do you use for mobile testing? Was that Browserstack?
which framework you use for app development?. I am using flutter from last 3.5 years
have been experiencing the same issue with mb air m1. thought it was some issue with ventura
very interesting. I used my M1 Pro Max with 80 charger with USB-c for about 6 months. My settings "Automatic" on battery and on power. I still have 100% of health. About two weeks ago, I switched to Apple Dual-usbc 35 watt charger when I am connected / charging at home and use my 140w MagSafe only when I need to charge it quickly on the go. Still 100%. That being said, my loads most often using less than 35watts (monitored it with iStat menus), as I use my macbook at home with lid closed (screen takes about 8-10watts) and not doing much heavy loading (i.e. exporting some longer videos few times per week via Compressor or directly via FCPX, which is using about 35watt at peaks).
Hi, as someone who is using mag-safe all the time I can say that it works for me. Rn my MacBook Pro 14 has something about 8 months, and capacity is still 100%, I use it for academic things as Well as coding + internet. The biggest problem is safari, I cannot use chrome because of apple password manager And other devices from apple Or can I?
Whatâs more Iâm trying to not exceed 30/40% of battery that problaby helps too.
Thanks for video !
question: I use magsafe. If I want to use a powered HUB, most of those are trying to put that power "through" to the macbook. I didn't want that, seems hinky to have two things feeding into the battery.
And at 6:04 you confirm mac doesn't do that- it says 'no thanks' and uses magsafe. Presumably the same would happen using a powered hub.
But, would that powered hub still power the stuff connected to it?
I'm trying one of those charge limiter apps because it seems batteries age better if working below 80%. I've been using the AlDente app for a few weeks... Does anyone use a charge limiter and saw any difference? The battery health on my M1 Pro MBP is around 93% after 7 months, mostly plugged via Thunderbolt to my monitor... So I'm also going to use MagSafe primarily. I didn't know it turned off USB-C!
My issue is with caching. I have a 16gb MacBook Pro M1 Pro and it is pretty obvious that due to the memory being shared with the GPU I frequently hit coincident excessive CPU and GPU usage at which point it heavily caches and really slows down.
That THAT happens frequently worries me about my SSD life.
Hello, good sir. I just switched from windows to Mac OS. I am a fresh MacBook user and I am currently watching videos on how to properly take care of my device. There are lot of things that I need to know, I guess, but there is one thing that I wanna know for sure, for now - which is the best method when you are not using for MacBook: 1. just close the lid; 2. put it on sleep mode; or 3. shut it down? I really hope that you'll notice this comment. Thank you.
IStat Menu will help you a lot with a ton of details you were looking for in this video. Power draw, watts in, detailed battery usage overtime.
Yeah, I'm not sure about this one. I've almost exclusively been charging using the MagSafe cable & after 8 months my 14" M1 Pro MacBook Pro is down to 87% of it's maximum capacity. So I don't think it's the USB-C thing. I do have a lot of Electron apps open on my Mac at any given time (VS Code, Spotify, Discord, Messanger), so that could be an issue. But it also could be a myriad of other factors...
On my 14 inch MacBook Pro (M2 Pro) I charge only with MagSafe, but it last me 2-3 days with light to moderate use.
How are you getting a full days worth of work on m1? I was lucky to get 5 hours on my m1 air if I was using it constantly. Which is still the best battery life I've ever experienced on a laptop, cause my 40w intel laptop before that would get about 2 hours between charges.
So for this techy lifestyle of being online all day my m1 would go through like 2.5 charge cycles.
My previous Macbook Pro 13 inch also went from 100% to 86% in just 8 months too. I didnt know why it happened cause i keep it plugged in all the time. I suspect its because i use an external display that works just by connecting to macbook with a single USB Cable for both power + data. So its probably the reason
So I have an M1Max 64GB Ram. I bought it about 8 months ago and I use it for audio production and video editing almost every day. Since I have also of perifferals I use and external CalDigit TB3 dock which has an external power supply. For the past 8 months I have been mainly keeping the computer plugged it through the day and using the e TB3 port to charge. The result is that I am at 95% Maximum Capacity. Keeping it at Auto Mode.
Now I am starting to use the MagSafe more and I am testing out AlDente, which allows me to keep the maximum charge at 80% and can discharge the battery. Let's see in 8 more months.
So, one year later, what is the answer?
Is it safe to change a MacBook M2 or m3 with usb-c (connected to a monitor for example)?
You should pay attention to what power can deliver cable itself. I was using Apple 140w adapter with genuine Zens USB-C cable - turns out this cable provide only 60w even if power adapted rated to 140w. I tried another USB-C cable from Baseus and its provided only 96w. So from now on I`ll be using only Apple USB-C to MagSafe as the only cable I have that can charge up to 140w.
The wattage of the cable can be visible in System Information -> Power -> AC Charger Information: Wattage (W)
Hey đ
My MacBook Pro M1 is showing me wrong Battery đ percentage.
and
its getting worse every day !!
My MacBook Pro M1 Battery was working well in the beginning, then
it started to shutdown at 20-25%,
then it started to shutdown at 30-40%,
now it shutdown at 50-60%
its horrible now ???
Now i don't know if the Battery has gone bad or not because it health shows as 96% and lifecycle are less than 150.
One weird thing is if i disable the optimise charging and then charge it full capacity, disconnect the charger - and use it for some time the battery stays at 100% for some time even if i use multiple apps -
what i mean : either the Macbook is reading the wrong stats of the battery because there is no way, if i use multiple apps for some time and the battery stays at 100% because apps like safari with 20+ tabs, VSCode, and Few other apps definitely using the battery sucking it and it shows at 100 % and then diea at 50%
We can't even reset the SMC or NMRAM or whatever on these new MacBook's .
Is there any way to or similar way like SMC reset on these new machine at least we can try to get the stats right ?????
I think that macsafe is first choice for apple because if you plug in some usb c cable with less power chargong or display with usb c macos could not recognize charging source properly.
This video keeps haunting me. I am big into all cars, especially EVs, and love my MACH-E. I know today's modern Li-ION batteries usually drop about 5% capacity regardless of use, during the first year ( or about 30k miles in EVS. They then level out and degrade much slower unless you fast charge them aggressively. ) . I have been playing around with a few ways to charge my Mac M1 recently to see if the idea of the weak charging was adding to the issue. What I noticed in the System Information app, under power, is that some TB hubs lie about their power out . I have three. two of them were advertised that they supported 100W, yet the Macs say they only provide 60W. The third I plugged into the MagSafe and while it was rated at 140W, it only reports to the Macs that it supported 100w.
So that was interesting. One thing I WILL ABSOLUTELY SAY! As I have tested it, is when the power supply is only 60w, I have found the Mac M1Pro to be very prone to odd crashes, when put under heavily load, like a day of Zoom meetings. Having a 90W or higher supply, even through USB-C charging, the Systems have been more stable, by a LOT. Weirdly enough, I run the Max on high power, and it is more stable in both cases ( low and high power ), than the M1 Pro. At 60W, the M1 Pro will crash or drop audio drivers a couple times a week. at 90w or above, its rock solid. It is something I have not quite figured out why, but I AM working on it. Thank you Alex for putting together a video that piques my curiosity!
BTW, Most auto manufacturer of EVs don't unlock their 100% of their battery capacity for this reason..
I am currently using m1 pro 16'. the max tdp i observed on this machine is 60w. so it's showing i need more than 60W to not to drain the battery and charge the battery. If I use the usbc like your experience i get 80W by the anker hub but when i use mag safe i get 140W but do I really need 140w? The answer is no unless you need to charge your mac really fast. For any max m chips, I expect them to have much higher tdp so probably 80w is not enough. but I remember apple introduced new 240w cable that could use full 140w in USB c?
I always wondered if it is safe to use MagSafe connected to power source/charge my M1Max MacBook while using my 96watt self powered OWC dock at the same time.
I donât like charging thru my Thunderbolt4 port.
You said here that if Magsafe is being used the Thunderbolt/USB-C charging port/part turns off?
I hope sođ
But Iâm still not sure if it works that way.
Iâve had my M1Max MacBook for over a year. I mainly use MagSafe to power source the MacBook & I only charge thru Magsafe also.
My battery health is still at 100% after over a year of use.
Iâll continue to use it this way.
But I do want to know (I wonder & if itâs safe) if I can have Magsafe connected to power source/charge my MacBook at the same time while using my OWC self powered dock.
Not having or needing the dock to power source/charge the MacBook thru the Thunderbolt/USB-C port.
Thanks for sharing this video and information here.
This question has been on my mind since I just bought the OWC dock last month & I donât care to use it for charging or power sourcing the Macbook anyways, especially if itâs safe, I could just use the MagSafe for all the powering needs instead.
And use the dock just to connect my other peripherals (devices) when needed.
Nice content as always.
I like your channel a lot.
Thanks again for sharing.
Magsafe is just a connector.
Your cable is probably the first weak link.
You can put out 140W via Type C. There is nothing that Magsafe can do that a type C cable canât when it comes to power transmission and negotiation.
here I am getting around 7.5 hour m1bp {77 cycle count 100% capacity } but on Monterey I was getting around 8.5 / 9 hours , Ventura is indeed is main culprit
Pretty sure it prefers MagSafe because if you have peripherals, those could draw power, or maybe it assumes that if itâs plugged into something thatâs a dedicated charger, maybe itâs more consistent or something. Thereâs also the chance that maybe the maximum power input is what is getting from MagSafe and itâs preventing overcharge.
I think energy impact is an instant measure. Maybe it will be better to look at 12h power to see actual impact over the last session.
I have an m2 MacBook Pro. I would like to see your takes on it cause it donât have MagSafe and In my opinion I feel that it donât last as long as an m1 Mac book pro.
Alex z , awesome content as always! Quick question: does earthing effect the battery health?đ
It helps MY health, maybe :)
Yes the Mac will always pull from the power source with the most wattage (which is the MagSafe).
If you're on USB-C PD (90-100W max) and you're doing heavy CPU and GPU work that needs >100W it will pull the extra from the battery and you will see the battery drop even while plugged in. This obviously causes additional wear on the battery for no good reason, if you know you're going to be doing heavy work and need more than 100W sustained then just use the MagSafe and keep your battery a little healthier.
Also changing the energy mode to high power is of little benefit in my testing. Leave it on automatic and it will up the power levels when needed and more often than not lower them to low power about 90% of the time which means no loss of general system responsiveness but gives you a nice hour or so of battery life. I gave up trying to act smarter than the Apple power management engineers years ago and just leave power management to automatic now :)
Honestly I kinda wish Apple removed those options from the settings UI. Changing them is rarely needed. I feel they should have put them in the pmset utility for those that *really* want/need them.
I think you have the right answer.
Magsafe is literally a dedicated port to supply power. If the computer needs more power than what we are giving it, then it's going to use the battery. USB-C and everything we have connected with it can cause (I imagine) all sort of issues i.e. it draws from the battery to "keep up".
That being said, I believe the "optimized battery"-setting is not doing what we expect it to do (if it works at all), which cause unnecessary "frustration".
Apple should find a better way to communicate these issues.
I recommend everyone to look at your comp maximum power draw (everything connected to it) and what you're feeding it.
@@tk42won Optimised battery charging is just Apple's term for 80% threshold charging with some "AI" marketing crap thrown in (just usage pattern match at the end of the day). It is good to keep it left on as it does a decent job of not over charging your laptop if it doesn't need to be which will help long term.
@@satysin630 That's what I meant by "not doing what we expect it to do".
Because mine is always at 100%. I have actually seen it discharge ( a long time ago before I removed the battery icon so I stopped looking at it and become annoyed) but it was an extremely rare thing. And yes, I've tried resetting it et cetera. *shrug*
Thereâs no way that chassis can deal with 80W of dissipation for even a few seconds, the high power supply rating is to allow for rapid charging.
I have M1 Max MBP and itâs been plugged into a T3Plus dock the whole time and itâs show capacity at 100% Cycle count shows 5. I have settings on Automatic.
Coconut battery is what I have used for years and years to record all my portable devices' battery levels and health. it also shows realtime data on power inputs and outputs.
Excellent application I recommend.
I personally love MagSafe, but most of the time I use my laptops at one of four places docked, which also provides power at the same time. Add in the amazing battery life of these things, and I rarely find myself using MagSafe at all. But if I do need to charge while out, thatâs what I have in my bag.
that's the most sensible use, I do the same
Any update video to this?
The icon of vscode can be changed. It's a custom icon but the same app.
The Mac will simply ALWAYS prefer the solution providing the most energy that is currently plugged in, and only drain energy from once source at a time.
So as Magsafe is 140W from your brick (and as Apple used USB PD through the USB C, thus limited to 100W) Magsafe will always be preferred when plugged in.
Try to connect a 100W adapter through USB C and a 60W adapter from magsafe and you'll see that the USB C charger will remain in use and the Magsafe one will be unused.
Interesting. I have never even unwrapped the Magsafe charging cable or charger that cawe with my M1 and M2 MBPs. I USB-C charge all the time since I have USB-C chargers and cables in most rooms of my home/office. So far no issue with the battery drain, but the M1 does drain noticeably faster than the M2. Perhaps I can get by with this because I buy the base MBP models and usually have a just a few projects under development because my brain needs a memory upgrade.
đ it may also have to do with my heavy use of the gpu+cpu
MagSafe always overrides anything else plugged which seems to make sense to this theory.
The wattage is exactly why you canât have a high power mode on the 14â since itâs hard limited to 96watts no matter whatâs plugged in you simply canât pull more wattage to the chip.
Reason the 38-core graphics on a 14â is about 15% lower then a 16â version. The juice isnât there. So take the 96w brick to an m2 max 38 gpu 16â and boom youâll see under heavy load your battery DOES in fact drain a few % before going back up. (Side note 38-core runs cooler then the 30 in the new 14â because itâs the first time itâs hard throttled via software/hardware limitation. Less use = less heat so the folks saying donât get the 38 in a 14 itâs a hot mess are incorrect itâs better than the 30 in my testing)
Of course you need a sustained load of over 5mins straight to do this but you will in fact find it.
The MagSafe charging port âover ridesâ the Thunderbolt4 port when using both the Magsafe cable & a Thunderbolt4 connected self powered dock (96watt OWC 11 port)
for the power source/charging?
Iâm trying to figure out if it is safe to use my Apple Magsafe 140w power brick while using a 96watt self powered dock at the same time.
Thanks.
@@iforgot3942 correct, if you plug both in it will only charge and use the MagSafe and ignore/not take power delivery from the input on the thunderbolt port.
If this is 2015, I will definitely still the fan of MagSafe. But after so many years with external hub with PD, Iâm ok with both. Probably MagSafe in Laptop mode and 100W PD Hub in clamshell mode.
I had a pretty weird issue with that. I use my Mac mostly as a desktop substitute that I can carry somewhere when needed, so I'm always plugged in. The optimize charge never worked for me, not once I saw my Mac being kept at 80%. Now I use Al Dente.
The number of days per cycle went from 1.3 to almost 4.
Don't know why the Apple implementation never worked for me though.
It should work after you use it away from power after few days. It just learn from your using behaviour.
Hey it works for me it has kicked in since last night... I have been using my new MBA M2 since March 9...it appears it took about 20 days for Apple to learn my usage behavior... Since last night, it kept on sitting at 80% of battery even if I keep on keeping it plugged it also tells me the reason for it being I rarely use my laptop on Battery...
@@samad0289 It never kicked on for me back when I had my intel mac, the implementation is very iffy if I'm going to be quite honest. Personally I ended up also using Al Dente and had it limit the charge and best part is that no matter the operating system the machine always limited the charge to 85-90% as I asked.
So I have a LG display which supports USB C display output and charging. I've kept my M1 Pro MacBook 14 plugged in all the time and Apple has limited the max charge to 80%. After 4 months of use, the battery health is still at 100%. Let's see how this continues.
Another way batteries degrade is if you're charging frequently from a low charge state (0-20%). It will generate more heat initially and heat does degrade the battery. That could also be an issue.
I'm interested to find out about your experiment with only using MagSafe. Fingers crossed for better results! đ
I've bought my 16" M1 Pro in December 2021 and have used it daily, always plugged in on the Magsafe (i never use it on battery). My battery health is currently at 92%. I'm not sure if this degradation is normal for 1 year and 3 months... But I don't care much because as I said, I never use it on the battery.
One of the issues is that Apple's Optimised battery charging is a bit flawed, every time you disconnect the laptop from the charger or change the way you use it a bit, it needs time to understand when to stop charging it and will keep pushing it to 100%. I use AlDente to keep my battery from charging over 80% when working at my desk, and let the battery discharge to ~20% once a month. Might be worth checking out
I also use AlDente.
Tell me: did your battery degraded?
Battery capacity?
@@agj03921 On my old MacBook I got down to 87% health in 1.5 years relying only on Apple's optimised battery charging. Since I got my M2 Max I've been using AlDente, still very early to say anything but I'm at 100% health.
@@LuigiSalemme thank you, Luigi đ
there is an app called al dente, is meant to keep your battery charged in the sweet spot to get the longer life possible for the battery
When you show the battery settings they looked a lot different than mine. I don't have the Energy Mode section and I can't find it. (Using a 14 M1 MacBook Pro)
Same, 14" M2 Pro. HMU if you find out why we dont have it
I always use the auto power mode, using vs code and 10x safari tabs, docker and running intermittent backtests that use about 30% CPU for 5 to 10 mins and I get atleast 12 hours, I only use the magsafe charger... I have deliberately kept my apps as minimal as possible because i am always travelling so battery is priorolity, i only have a few very efficient productivity apps like usage to monitor my loads. Using m2 max 32gb. As an electrician I would say only use magsafe to charge even though I never specialised in electronics or battery storage I still think it wouldn't be great for the battery to use a random charger especially if you're slightly discharging then recharging over and over thats not good at all. Magsafe is probably one of the best features of a macbook anyway.
Iâm not understanding why everyone uses chrome. Seems like it has a few major issues to me like being a resource hog and Google scraping your usage in the background.
Thanks for the great videos, I love them đ
thanks đ€©
My M3 max MBP is 90 % of the time in desktop mode , and i always let magsafe on it even if the studio display is plugged in also , and i've noticed that mt charge cycles do not move unless i take it away , a good Al dente replacement is Batfi , Free and i limit the charge to 80%
Interesting theory, how much is your cycle count on your old M1 Max MacBook? It should be really high then.
Is the "optimized charging" feature actually working for you? I'm using my MacBook 90% of the time plugged in to my USB-C monitor but after 2 months it didn't recognize that it should stop charging at 80%.
Yeah, unless it's a very high cycle count, it shouldn't be the reason. Keeping the laptop at high voltage (close to 100%) is actually worse than cycling the battery (as long as you don't cycle it to 0%) and yes optimized charging is not great. Al dente works better for that.
@@_Digitalguy Thanks I will try Aldente. It's a bit sad that you need the Pro version for Clamshell support.
Is thunderbolt and USB-C the same thing?
nowhere in the video is mentioned that this only applies for M1 max chip and not for M1 pro...
I've been searching for the "high power mode" section of the menu online and I thought my OS was bugged or something... until I realized this LoL
I hope this helps for other M1 Pro chip owners
I've had an M1 Pro 16" for 1y 6 months now. My battery life is at 93%.. It's my main computer for work. I do storyboarding, animation and video editing. Almost always have it connected to the wall.I only use the MagSafe charger. My laptop keeps charge topped at 76-79% on daily basis.
3.5hour is bad even for gaming laptop if you are not playing, so it has something wrong with battery, or there is some bug or something, because I have two MacBook m1 pro and M1 and both work at least 7-8 hours, I do machine learning and at least two android and ios simulator running on it, but I haven't yet seen even old M1 to work less than 7 hours.
Couldn't you measure the MagSafe power delivery by putting your USB-C power monitor into the Apple wall brick and then plugging the cable into the power monitor? Or does the monitor only work in one direction?
Wow, I get a couple of days of coding when the power is out. I guess typing 'make' on a command line and sublime text are power efficient.
you can install the tool "Energiza" (via homebrew) which lock charging at the desired level (ie 80%) if you plan not to unplug it often
Oh cool! Many years ago I had a Sony Vaio laptop that natively supported this. I will be giving this tool a try. Thanks!
I use "Aldente" -a more powerful tool than just a charge limiter
@@Dimonina what else does it do?
@@almeidainf well. For my needs it's perfect. I usually work plugged in at home. Sometimes I go to the office, where I also plug my laptop. For the zoom-calls I need to go to a special room where the battery is used. After 30 minutes of zoom I return and plug in again. Aldente keeps a range of battery percentage, where it is not charged. I mean you can set 30-80%, which means that the charge will never be more than 80 and the battery won't be charged until I drain it to 30. So when I unplug my laptop for 30-40 minutes each day, my battery does not get charged often at high percentages, which is crucial for the cycle count. However, if you plan to sell your laptop when a new model arrives, I wouldn't care about the battery :)
Slightly unrelated but does anyone have any tips for RAM?
I have a 16G M1Pro (16in) and I swear to god it's wimpy in terms of concurrent running apps.
Just IDE; maybe 15 tabs in Chrome or alternatively 5-6 in Safari, Spotify (with downloaded music) and 1 other app of choice (Clock+Cal, Notion, Obsidian, etc). IDE is just vanilla (VSCode, PyCharm, IntelliJ, depending on the project)
Compare that to what I'm used to on Windows with 16G RAM which is 300+ chrome tabs, IDE with a couple plugins, WSL sessions and at least 5 SSH sessions to not-local machines, and spotify and notion, and lots of office apps open, and bitlocker running in the background like a menace (company machine) it's a bit jarring not sure what I'm doing wrong đ€·ââïž
Contrary to what is said out there, 16GB of RAM is no longer enough for Apple. I upgraded from M1 to M2 exclusively to increase the RAM to 32GB. The M1 already met my needs perfectly.
What happens is that the operating system makes heavy use of swap and slows down apps running in the background, so if you really need more memory, this is the only way, the whole circus of not allowing RAM and HD upgrades on the MacBook Pro is terrible.
I have a M1 Pro 16â and on MagSafe usually will do 130watt. On type C using a similar 140watt adapter getting an average of 88watts.
Still giving me a full day with VS code,chrome,slack,discord running on the background
After discovering Intellij Fleet :) never gonna go back to VSCode :P. And that's an interesting icon :). Usually VScode has green if that was insider version. Related to charing, the closest you stay to the official charger voltages/amps and power delivery the better. An here correct me if I am wrong, with power delivery you can mess you battery cells if you have 80W delivery and laptop is eating 140W under high load.
I havenât tried Fleet yet. I suppose if youâre a JB user, that will feel like a natural extension of your toolset. Kinda like if you are using all DeWalt tools.
i have 14" mbp m1 max and i'm at 87 max capacity and cycle count of 284...been using the battery as a battery instead of being plugged always. i run R a lot and and other related tools. so i think that is jus normal battery wear.
Aight, so if you are using a lower wattage power brick than it is specified for your mbp, once in a while when it is running power hungry apps it WILL drain your battery bc the power coming from the wall is just not enough, causing these battery cycles to grow. Just use whatever is given to you by the producer and you will be good.
my m1 air battery droped to 86% in 6 months and i use original usb c cable and the charger , i think the problem is keeping the mac pluged in all time
Another M1 air here. Similar issue. I'm @ 74 cycles & 84% battery health. Noticed quick drop early on and took it to Apple Store with my concerns and they just shrugged and said it was "normal". My guess is that the battery degrades due to all the heat with heavier work load/gaming, since it has no fan. Having it plugged in should make the battery last l o n g e r, not shorter... and yes I'm doing everything how apple recommends us to: "optimized battery charging" and all that jazz. I simply gave up and stopped thinking about it. #FirstWorldStruggles
I bought my M1 Max 16â in November 2021, mostly use it plugged in to my USB-C Dock which outputs up to 100W and I almost never reach 100W of demand. Still my total capacity is already below 90%. Interestingly, it decreased faster since I started using the MacBook more on the go or to watch a movie in bed, i.e. using it on battery for a while, then plugging in and charging again. Also, the optimized charging where itâs supposed to stop charging at 80% never really worked for me, itâs always at 100%.
I think the optimized charging only (or mostly) works with MagSafe. At least that's my experience with my M1 Pro MBP.
I recommend using AlDente to limit charging to 80%. I bought a M1 MBP around the same time as you and the battery health is still at 100% (it's probably gone down a bit since they always start above 100%, but still.)
Sitting on a MBP 2021 M1 14" with the m1Pro chip. have been working on it all day. several teams calls. VS code open most of the day 36% battery left now and the estemate is 3:52 of battery left.... Can`t complain. battery health is 95% after 11 month of use.
i have a theory and that is thunderbolt port is absolutely for transferring data and not actually for charge and when you plug-in mag-safe for charging logically disconnect from thunderbolt port for better transferring speed.
Checking the activity monitor and looking at chrome I'm starting to think that it might be better if I switch over to Safari.
take a look at arc, i just got it and its really nice
I have installed chrome but I always use safari at least it light
I used an M1 Macbook Pro for iOS Development and Xcode for close to a year now, and throughout those time I have been using an external monitor cable (USB C) as my power source. I was shocked to see that my battery maximum capacity went down to 84% with 298 battery cycles in less than a year of usage.
My optimized charging used to work where it would keep the battery at 80% charge and I think after one of the OSX updates it stopped doing that and now it always charges to 100%. I am also noticing that battery started more rapidly to degrade and now its at 90%. Solution anyone to enable optimized charging again?
I used AlDente Pro, mentioned in a few comments here. They have documented battery optimization recommendations using their app on their website. I'm not affiliated.
Hi Alex, I love you channel, you do a great job! I noticed on your desk, you have a mug with a Progress logo on it. Do you code in OpenEdge ABL? I like this language a lot.
thanks a lot! i have never used openedge, but i did get that mug for speaking at jsmobileconf a few years ago. itâs my favorite mug.
My mac m2 pro, mostly used with MagSafe and while connected. Afer around 9 month of use the battery capacity is 93%. I am afraid that's fairly typical for batteries :(
even though I mostly use it connected it suggests cycle count was 29 O.O
If you know anything about modern batteries, it's that the surest death is cycles. If you're under-powered and over consuming. You have high drain, using yout laptop at 80-90% capacity, but feeding it 60% capacity, it WILL drain the battery. Because physics and math. Drain = cycles. Cycles = death.
Heat should be a non issue, but I don't use the GPU on mine so IDK how hot it could get.
I donât think charging the MBP using thunderbold is a problem: I charge my M1 Max MBPs (14â and 16â, bought on release day) and M2 Max 16â MBP via the Pro Display XDR and they donât show the drop in battery health as yours.
You might never go over 100w. The CPU only usage never showed me more than 60w of consumption. In heavy CPU+GPU it might use more power and use the battery while on plug.
After 3 months of use my M1pro 16inch MBP Battery health is at 98% (42 cycles) . Is this normal?
general thumb of rule is that you don't let Mac go under 20% and toggle on smart feature for charging it won't degrade , I have 77 cycles and 100% capacity
Do you use aldento? App for that
đ what app are you use for rpm and temperature monitoring?

I think this theory is applicable for MacBook 16â but if using the the USB-C cable from Apple display it will be ok because power delivery is 96W and it should not have a damage to the battery
