Thank you, this was very informative. I was able to resuscitate a Samsung Note 3 that had been unused for about 4 years. I ended up charging the battery a lot longer than depicted in the video. But in the end I got there. I think the battery was reading about 3.8V when the phone finally came on (first reading after "waking" the battery was 2.5V). When I was charging my battery, I kept my voltmeter connected to the contacts, which gave me real-time battery voltage level. That was really helpful to keep an eye on the charging process.
It was explained extemely well and I am very grateful to you; also found it was deminstrated so well that I was able to follow you since simple terms and slowly explained. Thank you so much. I wish all other videos were done similar to yours.
I am a technician this is not fake. He is correct this does work. The battery has an electronic circuit inside to stop them from going to zero volts. This is also what happens to laptop batteries but because you cannot open the laptop battery it is harder to jump start if not impossible. Sometimes, in a laptop, it will be only one of the cells that go low. You cannot open laptop batteries without damaging the battery case. If you leave them in storage they can go below the recharge line. Great video. Thank you.
Great explanation! My problem is I broke the micro USB connector on the phone and was looking how to fix it, but I stayed all the way to the end of this clip because it was very educational. Thanks.
@@UltimateDIY I did it but now my phone is just coming on the galaxy screen then going off on it's own and then again the screen comes out and this goes on what shall I do
Yer dog was tryin to tell me something but I don't speak his language. 🤔🤨 Awesome job explaining this you make it a clear relaxing and easy to understand topic. Salute!
This is SUCH GREAT INFORMATION! And the same principle works with different kinds of batteries and phones--I just used it to jumpstart my Samsung Galaxy 8 active battery after prying open the phone. The phone store probably would have tried to sell me a new phone! Doing this makes you feel empowered! ;)
It worked! Thank you so much, I thought I had to look for and buy a new phone battery, now it's not necessary, the old one is fine, it just needed a jump start.
Great and helpful video. On another video I watched, the guy recommended holding the red & black wires against the battery points for about 5 minutes to get it charged properly
The actual required duration depends on many factors, so it's impossible to give an exact number. For some 5 minutes cound be perfect, for others not enough or worst case too much.
I'm in Jamaica Beach, Tx. Last commenter...want to swap locations for a day? Haha. Thank you for your instructional video on this topic. I'm hopeful to get my older phone revived enough to save everything onto flash drive...
Nice one. Resurrected my 10yr old Nokia battery that I'm charging to use on a DIY GSM network using a software-defined radio. I seriously thought the battery would be toast after living in a drawer for several years.
Very informative, thank you. I didn't know that the Li-Ion batteries were that "smart." Here is a challenge for you that you might find interesting: Some phones have the contacts for a wireless charging pad to put inside the phone but the wireless charging pad is no longer available. I tried connecting a wireless charging pad made for a Galaxy S3 to my LG G4 with no success. How easy would it be to make your own wireless charging pad? Is it just a dumb loop? How many turns? Or is there a single diode? Or perhaps a FWBR? I tried searching with no luck and was not going to destroy my Galaxy S3 wireless charging pad to find out.
Thank you for watching. I think it needs some electronics to controll it. For a phone that does not have this option there are aftermarket pads that you just plug in the micro usb port. Although that uses the port so you are stuck with wireless charging.
Seen a few videos on this. Some say be careful and then they look like they have a plane to catch. Like how you followed steps and have respect for what you're illustrating.
Hi, good video. I have a problem with the batteries on my wife's LumeaPercision Philips device (light epliator). The case there is that there are 2 separate batteries but they are connected in a pack. If I heard you correctly I have to charge each individually, right ?
there is a tip. if you dont want to sacrifice a USB cable than pluug a usb cable into your laptop or pc and let it connect to your phone(battery inserted.). sometimes this do the trick without cutting a USB cable.
I enjoyed the video greatly! I was browsing videos of how to replace the charge port (didn't have to do that thankfully), but liked the demonstration that you gave, would've liked to see the doggie (haha), I understood your graph, and it's been many years since engineering school for me, but it makes sense. Out of curiosity, what is/are your native languages? I'll browse some of your other videos, this one was worth the 20 minutes.
My *Samsung Galaxy Note 1* Was Dead. I Havent Even Used It Since 2016. But This Video Is Super Helpful!! Thanks For This Video And It Worked!!!!!!!!!!!!
There is no safe or proper way of rescuing Lithium batteries that drop below 2.7 to 2.6v, this is because when a lithium battery drops below a certain amount the chemistry is forever changed in the battery. Most of the time you end up with a battery that will not hold charge after a small to medium amount of charges, or they can even explode. If you don't mind the possibility of a exploding mobile phone, then get a universal batter charger that has adjustable pins and can charge pretty much all the batteries on the market, they only cost around $3 to $5 from Ali Express, Banggood, or any other Chinese site.
This is partially correct, but there are several big channels on youtube that tested revived lithium and had 0 failures or loss of capacity. So, I really don't know what to say about this matter.
@@UltimateDIY it's a little more communicated than that. Basically you have 3 pin or 4 pin batteries, most genuine batteries will use protection circuits using mosets, diodes and resistors to prevent overcharge, overheating and even cut off when a battery dips below a certain voltage (when the chemistry changes) now when you see 0 volts, often this is not the real value, and often why when charging within seconds it jumps from 0 to 2.7 or above. So some PCB protection boards prevent you seeing the real value. A battery that has discharged to 2v or below will definitely have some internal damage to the chemistry, at this point, I would consider the battery dangerous and the severity is based on the capacity of the battery, since a 800mah battery will likely just smoke or die, while a 4,400mah battery can smoke of explode, the energy in higher batteries is far more worse.
Instead of using a computer as a power source for the jump start, can i use a regular wall outlet or maybe my laptop? I just dont have a computer tower.😊
I came back to do this video see if it could fixed old phone that is a old phone that is a touch screen and same for a tablet because this one device always back out at last three times and gets back on affer all the times of going black and i guess it still charging but i think it kinda would need to be fixed just like the phone so maybe i do a reset to see if it helps.
@@UltimateDIY i knew about 12v and other auto and marine deepcycle. i did not think to apply it to cordless no. but i have a pile and will see. Cellular not at all. but we get insurance on devices anyway. so why mess with it. However other freinds do not. i wil use this soon
I will try it 2mro n give u feed back. My ph was off for a year n now it dosent show chagring. Was looking 4 how to jump start battrey. Hope it works 4 me too
Great video, ive used this process with my dewalt tools. Old batteries were "shot" so i hooked the old battery up to my newer 20v battery for a very short time. It resurrected the old battery Im going to try your prrocess on a samsung a23 that has the same symptoms. Thanks for sharing
@@UltimateDIY just wanted to update you and once again thank you. I just finished jump starting my battery out of a galaxy a21s (a215u). The phone would flash the charging circle for a second and go black screen. Using your steps I found the battery was at 2.01v and I rigged my multimeter up while I tapped into a USB power brick charger. Once it hit 3.7v I disconnected and tried the regular plug in charger. It's ALIVE! . Thanks again
timestamps would be super helpful if possible :) Would double charging from a split usb lead and a direct charge through the port at the same time help?
believe it or not i was very interested in watching the whole thing, even though I knew it would not help me since I have a Pixel 2 XL and no removable battery... I've always liked watching gadgetry. Great job "showing everything". But maybe i can ask and you will know? My Pixel 2 will not accept a charge, i have tried every troubleshooting sequence including a factory reset. But even after that, and depleting battery of charge, then trying to charge again, I get the unhelpful battery charge icon, but even after several hours charging it still wont come on. I noticed that the screen was bulging...
Worked like magic. Have an old Xperia X10 in my drawer that refused to start charging, even if the battery is like 3.6V. After a few tries with this, it started charging.
@@UltimateDIY thank you I'm testing it right now I just finished holding the wires to it and have plugged it into the phone charger however if you don't mind I dont know how long I leave it on the charger before attempting to turn it on
Thanks I was thinking about to do this, but I didn't actually needed it because I had 2 phone batteries with like 2,8V. And the battery logo didn't appear while charging. So I assumed that the batteries were dead. But yeah they weren't 0,0V so charging it with the correct adapter did the trick for me. It only took long though to get it to work which was at 3,8V. Thanks for showing this I might use it in the future.
Lol atm 1 battery doesn't wanna charge any further at 3,2v and then it goes down to 3V via USB normal charging. The other battery was actually at 3,8V and it turned on (but it crashed a lot of times due to water inside before), but I noticed I actually charged it with the wrong adapter which also was kinda identical to another phone of mine. That phone was useless to me anyways and I'm gonna throw that one away.
I've just charged the battery to 3,8V with doing your method with the original adapter instead of the PC, but it doesn't still charge after it. Every time if I charge it when the battery is into the phone the voltage will be lowered. On the battery itself there is 3,8V and also 4,35V but I assume that is the max. So idk what is wrong with it why it just won't charge after 3,8V. I've changed the USB cable and tried to charge it on the PC / original adapter.
Yes that must be it. Yesterday it was 3,8V and it went down to 3V. The battery was only into the phone. So I was thinking about to buy a new battery. Ty for saying this, because it probably will be the same if I bought a new battery.
Thank You for your time & knowledge good tutorial buddy just found spare heavy duty USB cable to modify & will try on my old Laptop battery as guessing same actions will apply but take longer to get it to chargeable level
@@UltimateDIY Thanks I know but mine is refurbished but he did-not charge the rechargeable cells 1by1 b4 installation which in another video I saw on YT while ago said he should have & secret is to now trickle charge it so I will use an battery box with leads own jumper leads takes aa aaa & C batteries + 6-12V In/Output & so failing that just remove all cells & charge them in my multi rechargeable battery - charging unit & reassemble later lot of work but laptop is immaculate & even has a remote control for watching movies on big screens via HDMI & not risk losing my new Notebook when away from home
Sadly I tried that too a few times and it did not work. The problem is that most laptop electronics flag the battery as bad, even after a single cell goes once below the minimum safe voltage and even if you charge them individually, the electronics is still locked. You need to reflash the electronics. But this depends a lot on battery manufacturer and model. You can try, maybe you are lucky, but be really, really, really careful with laptop cells, as they can cause a fire quite easily if you do anything wrong, even after you put it back together.
I received a new battery but the phone is still not turning on. The last (-) pin with (+) shows 0v, other 2 (-) pins that are in middle shows 3.70v. Its normal?
@@UltimateDIY I have the same as in the video. The battery has 4 pins. 3 (-) and 1 (+). When I check the last (-), which is closer to the side with (+) shows 0v and the other 2 (-) in middle with (+) shows 3.7v.
That is what I try to say. The fact that is has 4 pins does not mean it has the same configuration for them. As long as you get 3.7V between 2 of them, then your battery has a good charge. But without seing myself I can't give you any advice.
I did this but I have a question, I thought it might be my battery the issue but now I'm not quite sure, maybe you know: So, I bought a new battery anmd the phone didn't turn on, when I plugged the charger with the battery on nothing happened, it didnt even hot warm while charging. Nooow, when I plug the phone (after doing what you did here) the phone gets warm, but no sign of turning on (The screen is dead, so it's harder to see if something actually going on), my question being, do you know what could be the cause of this?
I know what your doing works. Ive done the same thing with cordless tool batteries and hit them for a couple of seconds, with a higher power source of course.
@Mohammed Kiani My Samsung Note Pro SMP-900 went into a short boot loop where the samsung logo would come up for 1 second then the tablet would go off. I couldnt get to any of the usual pages to do the download or the page where you can do the wipe of the cache. I tried everything I could find on the internet and nothing worked. Then I changed the good battery in my Samsung phone for an old one and trhat phone went into a boot loop right away. So the dead battery caused it to boot loop. When I put the newer battery back min it worked fine and booted up normally. So I ordered a new battery for the Note-Pro SMP-900 and I think it should boot up normally or at least take me to the screen that will allow me to correct the booting problem. I hope that helps and when I get the new battery I will let you know if it solved the problem.
Just to be clear my Samsung S4 phone works normally even tho it is old. I put the weak battery from another S4 phone into my Samsung S4 phone and it went into a boot loop. When I put the good battery that was in my S4 phone back in the phone it booted up normally SO A WEAK BATTERY THAT WONT HOLD A CHARGE WILL CAUSE THE PHONE TO BOOT LOOP. I am going to change the battery in the 12" Note Pro Tablet and see if that solves the issues of boot looping on that device.I will let you know. I should be here in the next couple of days. So look for my message very soon.
My Samsung Note Pro SM-P900 (2015) was totally bricked and it is now working fine with a new operating system. If you are still in need of help let me know and I will give you the info to get yours working again.
czcams.com/video/1MdCdyax3do/video.html czcams.com/video/Q0To5QRR950/video.html Go to these 2 websites The first one is the one I used to un-Brick my Tablet. It has a robotic voice talking but it is the best video I found and it works. If you have questions let me know. The second one tells you how to get the software and download the extraction program and the Odin program. Odin is actually in the tool bar of the extraction program. Its very important that you download the proper OS for your device. If you watch the videos carefully you can save your device. I did and mine was bricked pretty hard.
Hi, thank you for the video. I have a Samsung A40 which won't turn on or charge. I charged the battery manually just like you did, but when I try to measure voltage I get 0 volts. If the battery is dead, how come it draws amperage? Is that normal? Thank you again!

But yeah they weren't 0,0V so charging it with the correct adapter did the trick for me.
It only took long though to get it to work which was at 3,8V.
Thanks for showing this I might use it in the future.
Lol atm 1 battery doesn't wanna charge any further at 3,2v and then it goes down to 3V via USB normal charging.
The other battery was actually at 3,8V and it turned on (but it crashed a lot of times due to water inside before), but I noticed I actually charged it with the wrong adapter which also was kinda identical to another phone of mine. That phone was useless to me anyways and I'm gonna throw that one away.
I've just charged the battery to 3,8V with doing your method with the original adapter instead of the PC, but it doesn't still charge after it. Every time if I charge it when the battery is into the phone the voltage will be lowered. On the battery itself there is 3,8V and also 4,35V but I assume that is the max. So idk what is wrong with it why it just won't charge after 3,8V. I've changed the USB cable and tried to charge it on the PC / original adapter.
I think the charging circuitry is your phone is defective.
Yes that must be it. Yesterday it was 3,8V and it went down to 3V. The battery was only into the phone. So I was thinking about to buy a new battery. Ty for saying this, because it probably will be the same if I bought a new battery.
Yup ☹️
Is it work for lithium polymer that battery was only attached/detached to circuit board?
As long as you can make contact on the charging pads it should work.
yep it worked although my phone dosent charge the battery by itself
Wow man you explained that soo good
Thank you!
thank you so much, It worked for me . I'm sooooo happy
Welcome!
that looks good. but what was the settingput on the charger
It's connected to a pc usb, so 5V.
Thank You for your time & knowledge good tutorial buddy just found spare heavy duty USB cable to modify & will try on my old Laptop battery as guessing same actions will apply but take longer to get it to chargeable level
Sadly, this will not work on most laptop batteries. They have more complex electronics. I have tried a few timesc, but always failed.
@@UltimateDIY Thanks I know but mine is refurbished but he did-not charge the rechargeable cells 1by1 b4 installation which in another video I saw on YT while ago said he should have & secret is to now trickle charge it so I will use an battery box with leads own jumper leads takes aa aaa & C batteries + 6-12V In/Output & so failing that just remove all cells & charge them in my multi rechargeable battery - charging unit & reassemble later lot of work but laptop is immaculate & even has a remote control for watching movies on big screens via HDMI & not risk losing my new Notebook when away from home
Sadly I tried that too a few times and it did not work.
The problem is that most laptop electronics flag the battery as bad, even after a single cell goes once below the minimum safe voltage and even if you charge them individually, the electronics is still locked. You need to reflash the electronics.
But this depends a lot on battery manufacturer and model. You can try, maybe you are lucky, but be really, really, really careful with laptop cells, as they can cause a fire quite easily if you do anything wrong, even after you put it back together.
Bro any other way to understand voltage
hey I have a question if my phone are not being turn on for a long time like several years will the picture or the memory in the phone will be lost?
No, they will not be lost.
Very useful. Great English.
Welcome and thanks!
Good video.
We need that tester device
Glad my video helped 👍🏼
I received a new battery but the phone is still not turning on. The last (-) pin with (+) shows 0v, other 2 (-) pins that are in middle shows 3.70v. Its normal?
I don't know for your particular batery model. You need to search on forums.
@@UltimateDIY I have the same as in the video. The battery has 4 pins. 3 (-) and 1 (+). When I check the last (-), which is closer to the side with (+) shows 0v and the other 2 (-) in middle with (+) shows 3.7v.
That is what I try to say. The fact that is has 4 pins does not mean it has the same configuration for them.
As long as you get 3.7V between 2 of them, then your battery has a good charge.
But without seing myself I can't give you any advice.
What are your thoughts about using hair dryer technique to heat up the phone and temporarily increase the voltage of the non-removable batteries?
Could sometimes work, but depends on situation. I also do not really like to heat up batteries...
Thank you very much. It worked.
Welcome!
Just ignore negative commentators, there will always be those
Thank you!
Thanks👏🏻👏🏻👏🏻👏🏻
Still cant turn on my Note II agyer trying this method sir :/
I did this but I have a question, I thought it might be my battery the issue but now I'm not quite sure, maybe you know:
So, I bought a new battery anmd the phone didn't turn on, when I plugged the charger with the battery on nothing happened, it didnt even hot warm while charging.
Nooow, when I plug the phone (after doing what you did here) the phone gets warm, but no sign of turning on (The screen is dead, so it's harder to see if something actually going on), my question being, do you know what could be the cause of this?
It's impossible to guess.
I know what your doing works. Ive done the same thing with cordless tool batteries and hit them for a couple of seconds, with a higher power source of course.
@Mohammed Kiani My Samsung Note Pro SMP-900 went into a short boot loop where the samsung logo would come up for 1 second then the tablet would go off. I couldnt get to any of the usual pages to do the download or the page where you can do the wipe of the cache. I tried everything I could find on the internet and nothing worked. Then I changed the good battery in my Samsung phone for an old one and trhat phone went into a boot loop right away. So the dead battery caused it to boot loop. When I put the newer battery back min it worked fine and booted up normally. So I ordered a new battery for the Note-Pro SMP-900 and I think it should boot up normally or at least take me to the screen that will allow me to correct the booting problem. I hope that helps and when I get the new battery I will let you know if it solved the problem.
Just to be clear my Samsung S4 phone works normally even tho it is old. I put the weak battery from another S4 phone into my Samsung S4 phone and it went into a boot loop. When I put the good battery that was in my S4 phone back in the phone it booted up normally SO A WEAK BATTERY THAT WONT HOLD A CHARGE WILL CAUSE THE PHONE TO BOOT LOOP. I am going to change the battery in the 12" Note Pro Tablet and see if that solves the issues of boot looping on that device.I will let you know. I should be here in the next couple of days. So look for my message very soon.
My Samsung Note Pro SM-P900 (2015) was totally bricked and it is now working fine with a new operating system. If you are still in need of help let me know and I will give you the info to get yours working again.

Go to these 2 websites The first one is the one I used to un-Brick my Tablet. It has a robotic voice talking but it is the best video I found and it works. If you have questions let me know. The second one tells you how to get the software and download the extraction program and the Odin program. Odin is actually in the tool bar of the extraction program. Its very important that you download the proper OS for your device. If you watch the videos carefully you can save your device. I did and mine was bricked pretty hard.
Brother never bother what people think because that's there loss🇬🇧👍🙏
True! But sometimes, when you just try to help...it gets to you...
Could this be done with an iPhone 7 battery? What would need to be done to get to the battery?
Sorry, but as far as I know iPhone batteries have small connectors, so it's close to impossible to do this.
Hi, thank you for the video. I have a Samsung A40 which won't turn on or charge.
I charged the battery manually just like you did, but when I try to measure voltage I get 0 volts.
If the battery is dead, how come it draws amperage? Is that normal?
Thank you again!
Hi. If you did the procedure shown in my video correctly and it still reads 0, the battery is bad. Even a short circuit will draw amperage :)
@@UltimateDIY thank you so much for the information!! I just ordered the replacement battery
Welcome!
OMG IT WORKED THANK YOU SO MUCH
Welcome!
i don't have a monitor volt how can i be sure to use the right one?
You are taking a risc then. You can maybe test with two LEDs in series. It should give you the correct wires and polarity.
my phone has not been on 7-8 possibly 10 years
Thank you so much
Welcome!
What if the phone has a usb-c port or an internal battery? Thanks for the excellent video!
For internal batteries it's close to impossible to do this.
Why?
