I'm glad someone brought this up. Fast charging is not great for your battery, especially over time. I just use an old 1.5A USB charger if I'm not going to need my phone for a while. The Chargie is a good battery management appliance as well.
My thoughts exactly. EV cars and fast charging….. how often will batteries need replacing? Similar to timing belts? 100,000 km etc?
I use a USB 2 charger with the old 5V/1A and it’s been great for the health of my batteries.
Lol
I tried doing this (manually) and quickly found out that the effort needed for keeping the battery in my phone within optimal percentage was bigger than the cost of battery replacement after two years anyways.
Also, using USB ports and not an integrated cable would be a great - if the cable breaks, just unplug it and plug in a new one.
If you have a rooted Android phone, and your charging chip supports it, you can do everything in software with acc (there's a Magisk module) and accA (configuration frontend) to control charging current and other settings (charging duty, temperature control, etc) with profiles.
Thanks! You made my day!
Found this after ordering a Chargie.
I have an old USB charger that puts out 150-170mAh, but even that will "overcharge" the phone say, overnight. (I get about 12% an hour with it).
I would think there might be a market for relatively cheap ~50mAh chargers.
With the fast charge technology most phones have at this point, if you NEED to top up the phone and it's sitting at 50-60%, you are talking maybe 10-15 minutes of quick charge to do so. And for normal/overnight use, a very slow charger would seem handy. And cheap.
Chargie should be fun to play with though.
Good thing newer phones are finally putting in functionality to control battery charging behaviour. Apple's has one where they automatically optimize charging rates based on your habits but it probably takes a while to train it, though. My Asus phone also has a fair amount of settings for control. One for controlling the charge limit, one for controlling the charging rate (lowest it can go is 18 W, though) and an 'overnight charging' mode that uses a combination of the two so that it would reach 100% right around the time you set your alarm. It's nice to see phone manufacturers not neglect this negative aspect of having such high capacity phones and very insane charging rates.
Some Android phones have an option to slow the charging to save battery life. My ASUS ROG Phone II has a "scheduled charging" option to have it slow the charge rate to finish charging at the time you set. So if I go to sleep at midnight and set it to finish at 8am it'll still be charging 7 hours later. I think the new Sony Xperia 1 III I have has it as well (so it might be in modern standard Android) although I haven't checked yet.
Even cheap Samsung phones are able to switch off the first charge. It’s in the settings menu
Just use cheap usb cables and power supplies for that easy barely 500mA. Computer USB 2.0 is also always max 500mA
Mark. Could you do a mini tutorial on soldering the not-copper wires found in some USB cables, and earbud wires. They include a lacquer coating which defies soldering.
Thanks
I never thought i would watch a video with this title 🤣.
Thanks! Enjoyed the vid! 🖖😊
Nice video. Thankfully I still have my old LG G7 charger that outputs 700mA, so it's a nice compromise. I would like to try this thou.
I'm pretty sure there are plenty of USB-C to USB-C cables out there with only 4 wires XD
What USB monitor would you recommend if not your one? Just any but yours?
If 500mA is slow enough for you, you can also just disconnect the data pins and leave them floating as well.
Awesome video.
What is this powerbank with removable batteries? Looks very usable
My Asus ZenBook laptop (think Apple Air form factor with Windows) has a configuration option which allows you to limit charge to 80% or 60%. True confession - i only found out about this a few days ago, while i had owned it for about two years. So Mark's video is quite timely!
I was thinking about doing something like this but with data cables intact for a phone that I use for tethering and is therefore plugged in to power most of the time. The usb data output will only connect if it senses a current output, so I was thinking about making a cable that has a resister that can dump out enough power to keep the phone from charging much but still allow data connection.
Do you know of any CC IC's that can do less than 150ma? I'd love to slow-charge some devices with a sub 100mah battery
You can also take a usb a to c cable and snip the data wires. It will assume a problem and be limited to 500ma
I once bought a cheap (3 euros) USB cable, it is over 2 meters in length and lets a maximum current of 300 milliamps through. It even can transfer data.
I bought like 16 500ma chargers that I use to charge everything, but this is also a solution.
one thing you can also try is to remove the data pins from the charger, and most phones see that as "ah I'm plugged into a 500ma charger" since that's the default USB spec
That used to be true but phones got a lot smarter now and they’ll regulate on their own without data pins.
I did the same now. I ordered low power chargers. I’ll be using them on all my phones from now on.
You could turn the box into something that holds the entire cable in a neat loop, like if it was in your pocket or something
I'm old-school. I would've grabbed a LM317. Good video.
i would like to have something like this when i buy a new phone. my old battery is already bad from use and age
I used a 12 ohm 10 watt resistor in a tiny box. Slows down micro USB charging to about 2 watts. I can watch youtube videos with the charger plugged in & it barely charges.
nice video but what value was the trimmer pot
4.7k. As long as it is greater than about 3k you can get the full 1.5A range of the IC
what about people who say the phone would get replace around when th battry fail becaer it hard ware can no longer keep up with the sofware
Slow charging while sleeping is an option in android now. For example OnePlus phones
Is there any buyable ready to use product, tht does the same?
I was hoping for exactly the same 😔
I just bought some usb chargers that are meant for small stuff like headphones or smartwatches. They’re typically under 1a output. 500ma is too slow, I like 700ma-800ma. It charges a typical phone just fine overnight. I noticed my battery life is better as well. The slow charge helps the battery stay cool and keep a stronger charge.
@@kl1wdr see my comment above.
I just bought an adjustable power supply with 15 Watts, i'm able to change the voltage and amperes of the charge. You can get them from China directly for arround 5 to 8 bugs, I bought them in my country a bit more expensive but don't have the hustle witha chinese dealer and I got it quicker. Search for adjustable power supply USB 15W and see a couple of them, mostly are blue and red, but I bought the black one, because the other two got outsticking pins of switches and the black one got a disc style dial switch, which you have to push and turn to left or right. I guess this type of switch lasts longer compare to the two other ones.
Would you be able to supply a link?
Once I decided to sort all my usb cables. 50% were 2-wire charge-only and only 10% could do at least 1.5-2A. My method for slow charging is just to select the worst one.
How did you test them?
@@sgas Same way, with a similar current meter. The cables you can get for random IoT devices are cheaply made and can never do more than 1A.
@@gabest4 so you test what the phone decides to charge at?
If i hadn't have this one, i would just use CV module that gives constant voltage on the output, input voltage range would be say 3-10V so that lion would give the juice to the point of discharge set at 3V (no need to have a battery with charge/discharge control logic built in) so having that constant voltage output, i would just solder some resistor in series, depending on how much current i would want to get out of it.. More ideally, id buy some CC/CV module (wait, i have one), in that case i'd just solder the wires on input/output and voila.. set the trimmers and let's go.. EDIT: why those caps on input/output? I have not done such a ting on my charger and worx perfect..
For Samsung devices you can disable quick charging in the battery settings.
Why cant you buy these off the shelf? seems crazy no company makes them
What are your scientific resources regarding the need to slow charge devices?
I feel vindicated for abusing my devices hahaha
Another (cheap-ish) way of doing it: If your phone supports wireless charging (qi charging), buy a wireless charging pad, which charges at ~800mA and just plop your phone over it
Rpot =1k ???
Datasheet of FPF2125 says 500mA = 1kOhm, 200mA = 3kOhm. So 1k pot is good if you are ok with minimum 500mA, maximum 1.5A. I think he might have used a 5k pot?

1st
I'm starting to regret charging my EV to 100% every night now.
most EV cars have an option to change the rate of charge and what you charge it to, you should see what you can do about that.
@@JessicaFEREM Yeah, but I left mine at 100% because I wanted maximum range. I've set it to 90% for AC charging now.
If you have a Tesla, 100% to you is really 80%. The car automatically expands the discharge range over time as the battery ages so you always have the same driving range within the warranty period.
@@TheUbuntuGuy I have the only Mazda EV, the MX-30. I have no idea if they apply the same sort of wear levelling. Regardless I think I'll avoid charging to 100% going forward.
@Arpad Toth Jokes on them if that's the case. The battery pack has an 8 year warranty :D
This seems to boil down to the harder you work your battery the shorter its life will be.
can you first open up the box and then talk about it? it's excrutiating to watch you fiddling around and explaining while i can't see whats inside. i haven't listened to anything you said before 11:11
He put a timestamp if you don't wanna watch the explanation and just want to see the inside.
@@ELECTROHAXZ timestamp says 9:24, box isn't open until 11:11. i'm talking about this.
