Why won't my Samsung Galaxy S II charge?
Whenever I try to charge my phone, it won't take a charge. What should I do?
I have had the same (or similar) problem with two different extended batteries:
The batteries seemed to not take a charge. When plugged into the charger, the phone would run, and a flash would appear in the battery icon—but the charge percentage didn't rise above 0%. If I changed to another battery, it would work normally.
Well today I found the solution (here)
I now have two working batteries :-) I think that the circuit in the battery that protects it from overcharging and undercharging needs a reset.
You need to replace the usb/charger port board they are about 10 bucks and not to hard to replace. From what I can see the board either gets wet or broken from the inserting and removing of the usb/charger.
I took a chance, bought a separate charger and battery, charged the new battery, my phone powered up when I put the battery in. After playing with this dilemma I figured this out. if I leave the phone on while charging, it charges - If I power it off it will not charge, in fact it drained the battery completely dead. By the way my old battery charges up fine. So I'll just leave it on while charging
I had same problem.I bought even a new battery.But I couldnt solve the problem.Then I realized that phone was getting hot near the sd card and in settings in battery part there was an app named media (android standart app) line consumes battery.
SOLUTION: If you have moved or install programs like theme (IU) or sync automatically to SD Card , move them back to phone memory storage.
My phone wasn't charging either. I tried the suggestions above, but none worked.
Then I noticed my phone battery was a bit loose, had a tiny gap, and was not connecting well with my phone.
So I pressed the battery terminals down to make sure it had a good contact with phone terminals and the phone suddenly turned on and started to charge.
Then I took a piece of paper, made it thick enough, to insert it in the gap to make sure the battery stayed tight, put the back cover back on and that's it it charged and worked just as before.
I have a Samsung GS2 T989 and had the same issue. It came to a point thatit would simply beep and disconnect itsef.... tried different solutions:
1) initially, I gave up on using the charger and purchased new batteries. Got a set of two plus wall charger (http://www.amazon.com/Hercules-T-Mobile-...). LOVED THEM!!! With two batteries, I had no need to use the usb charging
2) still tried to use the "half dead" samsung battery- simply charging it on the Anker charger instead of using usb port
3) worked for a while, but then started having issues in synching the phone to PC - USB was really gong south... so I reset phone. After restoring to factory settings, the USB port is now working 100%
good luck guys
It's an issue of samsung devices when battery is "too empty". The Problem is now that the samsung charger only starts to charge if it get's a response from the device if not it won't release any current for charging. The solution is that you need a charger which doesn't uses this technique, for me an old apple charger works. Most of the old chargers with currents below 1 A should work. When the display then shows the battery bar you can change to your normel charger faster charging.
