I had this problem: my phone (Arc S) died saying it had low battery (even though I had checked it just a minute ago with 25% still left).
I tried to charge it but nothing happened for 30 minutes.
I knew that taking out the battery and reinserting it after a while usually fixes this but this time it did't help. The phone could not be started and it wouldn't charge either.
Solution: Borrow a friends battery (if he/she has the same phone ) or buy a cheap one of the Internet (there are batteries for about 4 dollars).
Put the new battery in your phone and start it. Turn it off and quickly put the "dead" battery in again and insert the charging cable and it will charge and function as before!
My humble guess is that the charged battery leaves some juice in the phones circuits that stays there for a while and can help a "dead battery" charge again.
I know your problem : http://forum.xda-developers.com/showthread.php?t=1312398
No that's a workaround/patch to 0% battery issue caused by downgrading firmware from 2.3.4 to 2.3.2.
I've never downgraded! This problem is rather from the phones difficulties sensing the batteries power level correctly.
Thanks anyway!

Here is the problem :-
1. Full charged batttery (NEW) drain out within 2 hrs
2. Exec in standby mode, got heat (warm)
3. While charging, i put it on standby mode, few second later it wake up it self.
4. while open the cover, usually have to press the power button it's only wakeup, but this time its on every moment..
Tried solution :-
Problems occured while using gprs for internet, it hang so soft reset it... after soft reset everything is fine, but the battery drain out so fast... and the device is WARM...
Flashed back to original rom (o2) - still the same
Tried flashed to WM6 - still the same problem
i got 2 x batteries... the problem still the same (not the battery problem)
anyone can help out with this?
thank you so much
try using 2А battery charger .. I have had similar problems that I decided to convert the old computer power supply for charging purposes
I was going to say your battert's old and dead, but since you said it was independent from the battery, now I think the drain and the heating might be explained by a short circuit somewhere in the non-vital parts of the device, or a malfunction of the power control circuit, causing constant drain and heating up the battery.
As for the device beng constantly on, have you checked the power settings? If those are all right, they can stil be attributed to the faulty power controller...
I suggest you take it to a repair shop(since your ROM-flashing probably voided the warranty, so the provider will just turn you away...), they might be able to do something with it.
I suggest you check back later to see if someone more knowledgeable than me offered confirmation or another opinion...
Good Luck!
theres only one thing i can think of: Turn off your wifi when you dont use it Xp Thats the only reason i can think of when your device gets warm and the battery quickly drained ; D

I don't think so...the wifi doesn't use nearly enough power to heat up the device or drain the battery that quickly. Even with all wireless options enabled, but screen brightness set to minimum, the battery lasts approximately one and a half hours for me.
I think the quick drain and heating is caused by either a non-critical short-circuit or a faulty power controller circuit...
maybe you gor ripped off. what kind of battery did you buy?
The battery that im bought recently
same as the old one.
PU16A Li-ion Polymer Battery 1620mAh
everything i tried to save the power
everything off except the phone, the backlight set to the lowest.
im charge it with my charger instead of USB port from computer
Hey guys,
i have a Vodafone VPx now and all has been great, however yesterday it reckoned the battery charged from 8% to 100% in 10 mins, i left it on the cradle over night, and now the device doesn't show any signs of life apart from a red charging indicator. I took the battery out and metered it, shows up at 3.72 Volts, so battery holds charge. What can i do to get the device to power again?

I'm not an expert but I would suggest to leave the device in the cradle and try to boot it when charging it. In this way you can decide whether it's a battery or some other malfunction. Maybe the internal backup battery needs to be replaced, but I don't know if it would let the battery indicator LED to blink...
I replaced my battery because it showed that it's fully charged but when uncradled the device won't connect to bluetooth devices or regularly drops the connection, it even resets itself although the indicator displaying full charge. Now everything is OK. You may consider buying a new battery if it's older than 2-3 years, but first test if that causes this behavior.
hi,
actually i'm experiencing the same thing..
my BA if used to connect to wifi, not more than 5 minutes it will hang with the screen goes blank.. so is it because of my internal back up battery that needs to be replaced or my main battery that need to be replaced?
FYI, backdays before, i got notification that my internal battery runs dry..
Ive just bought a BA off ebay and it came with 2 batts, but 1 of the batts keeps causing the BA to turn off evern if the batt is fully charged.. odd hey?
speedy2009, I think that one was the original battery bundled because it has no value any more so the seller sent it with the machine, all in all it's not a bad device for it's years.
jilaxzone, don't know how to test this, because sometimes the device gives false alarms, I would take it to a PDA shop and let them replace the internal battery as this is cheaper than the main battery.
Also Ive figgered out that if the backup battery is low, it gets charged up from the main battery.
Should everything be lost from the memory once the backup battery runs out? Cos I did try this morning, taking the main batt out and left the phone for about a hr. When I put the batt in, even tho windows said the backup batt was completely empty, it still had all my info in windows??
Hi, the backup battery is responsible for the time and date. The other functions of it are unknown to me. Fortunately the ROM storage is not lost when the battery drains completely

If thats the case theres no real reason for a backup batt cos it only takes a few secs to alter time and date, like on a normal mobile phone.
Hello,
My desire, after:
an inability to restore nandroid backup
a possible corrupted sd card
a usb brick and inability to mount some nand partitions
and finally succeeding in fixing it, now using/running:
2.29.405.5 stock rooted rom
a new sd card (samsung 16GB class 6)
clockworkmod 2.5.0.7
s-off
seems that has battery issues. When it reaches below 30%, it drains a lot faster. In example few minutes ago, the battery was below 30% level and after sending a couple of sms messages the phone, without the "Connect the charger" indication shut down. Not even the battery icon was red.
What should I do?
After flashing the above ROM I ran an app called battery calibration (could this be the culprit?).
I haven't experienced such problems before the whole mess mentioned above.
Thank you for your time.
Well, it seems to me like a "classic" battery meter calibration issue.
TVTV said:
In order to calibrate the battery meter - FYI the battery itself cannot be calibrated, as Li-Ion batteries have a very low memory compared to old Ni-Cd etc. batteries - you have to go through the following procedure:
1) charge the battery to 100%;
2) let the battery discharge until the phone shuts itself down;
3) plug the wall charger into the phone, boot the phone up then charge the battery to 100% without interruptions.
If the above procedure does not yield the expected results, you can try fully charging the phone (LED showing green) with it completely turned off (after completely draining it). Again, the charging procedure should not be interrupted.
Source: personal experience - had to do this twice after installing new ROMs, as the phone was shutting down at ~14% (working like a charm now).
Regarding the matter of battery wear because of complete discharges, Li-Ion batteries do indeed have a lower cycle count than old-school batteries, but the standard charge/discharge number a Li-Ion battery can take is ~350, so you can't damage the battery pack by doing a full cycle per month (required to keep the battery meter accurate).
Good luck!

Did this work you mate? I have the same issue with my year old batter now... the phone shuts down @ 40% without any warning... and when I charge it, it starts from 0% and as soon as it hits the 58% mark, it jumps to 100% by itself... and i cant seem to figure out what the hell could I do to fix it... I tried calibrating the battery using the awesome method described here http://forum.cyanogenmod.com/topic/11823-battery-calibration-thread 3 times and nothing changed...
bump bump.. i really need help on this guys... :/

Weird that after calibration you still get that kind of issues, does this only happen on your current ROM? I have the latest CM in my desire and everything works just fine... Maybe try another ROM if calibration doesn't work to see if it's a hardware or software issue
i actually had issues with MIUI first.. the phone randomly shut down by itself but when i turned it back on, it was perfect... then i switched back to Oxygen and while everything was fine, suddenly one day the phone died at 40% :S and from that day on the phone charges to 58% and then instantly jumps to 100%... and as soon as it gets to 40% it shuts down itself... i guess i need a new battery but i wanted to see wether i can fix this one somehow so i can use it till the new one arrives...

same problem
i have the same problem
my phone turns off at 20% battery
calibration does not help....
and battery is not bad - it works fine
i'm sure its the problem with calibration

phone turning off at 20% is fine mate because thats the battery guards against any damage
most of the phones ( smart phones) switch off at 20% as going lower can damage the System .
It shouldnt normally..It's supposed to work fine upto 5%
Have a look at this, it worked for me (but you need a compatible kernel, most AOSP are so)

I have a battery / charging problem on my Gnex. The problem is that the battery won’t charge more then 60 %, drains quick and then the phone shuts down at 0 % ( in about 2-3hrs of use) and wont restart until recharged.
At first, I tought it was the battery so I bought one OEM on ebay. It did the same thing so I returned it and went to Telus store to buy an OEM.
Same thing happened with the new OEM. I then bought an external wall battery charger and charged the 2 batteries I have. When I put the first one back in the phone it said 12%?
I tried the second one which is the new OEM and same thing, its showing 12%.
I did a little test, I had 4.2.2 so I unlocked the phone and rooted (no more warranty anyway) I flashed back the ROM to ICS. No change.
So what I did next is I used the phone until it shut down at 0% and restarted it on the bootloader screen and left it on, on the bootlooader screen.
Well the phone screen stayed on for more then 3 hours, so I know the battery is good because there is no way that a 0% battery could power the screen for 3 hours.
So after it shut down from the bootloader screen, I charged it again, in the phone, and it went right back to 60%, I did try to wipe batt stats from recovery mode and battery calibration apps but no luck.
Is there a way to disable the auto shut down on the phone? The battery meter if definitely showing wrong charge stats. Is the battery controller part of the USB board or the motherboard?
The only thing I did not try yet is a custom ROM and Kernel.
Any ideas?
Sounds like a hardware failure... It's obviously not the batteries

I found where the Power Management with Switch Mode Charger chip is, on the motherboard! I wonder if there is some ways to access and modify the values of this.

For what it's worth, the same thing is happening to me. Charges to 64%, and it acts like it's only got a 64% charge - runs out fast. And I also tried a replacement OEM battery with no difference. I'm not completely convinced this is a hardware problem - though I guess it could be. I'm still stock Gnex (with the 4.3 upgrade - and come to think of it, this started some time after that upgrade). I was hoping it was some kind of kernel problem that i could fix by switching to CM. Anybody have any luck with that?
The same thing is happening to my phone, although I'm lucky enough to have it charge to 73%. Only realized the problem when I bought a new OEM battery and it stopped charging at the same 73%. I have a friend who has the exact same phone and will give her both my batteries to charge and see the results (with her phone then once batteries are reinstalled in my phone).
Outside of replacing the motherboard, would anyone know if there could possibly be a software fix? Has this happened to any other phone? If so does anyone know the results?
Thanks,
Stefan
My gt s6312 has charging issue. It never charge over 67-69% in my phone. I checked the battery in other phone its ok.....please help.....

Sounds like a hardware failure in the phones' charging circuit. Since:
- no software change (ROM or Kernel) fixes it
- no battery change fixes it
Then it's obviously the charging circuit in the phone. Time to get a new phone!
Well I've confirmed for myself that it is my phone charging circuit that's giving me bad info on my battery charge. I installed both my batteries in a friends Gnex and both gave me 100% charge reading on my friends phone. I then re-installed both batteries in my phone and both came back with identical 13% charge reading. So to me this is obviously not a battery issue.
Since my previous post in July my phone has gotten progressively worst. So I have now come to the point where I either have to replace the phone's charging circuit or replace the phone all together. I would much rather do the first as any replacement phone via my carrier would require me to pay more monthly on my contract.
So would anyone know with certainty where the charging circuit is located in the Gnex? Is it on the main logic board or the USB charging board?
Thanks
My phone doesn't charges above 70+,if i remove the battery and reinsert it it shows 92% after that it charges normally till 100%,again the same thing is continued in next session of charging. ..I tried calibrating the battery by removing the battery and hold the power on button for 60+ seconds and also tried the battery calibrating app..no use at ol...one thing is, if a use the mobile continuously it charges very slowly after 70+,if its not used again it stops charging but indigates as charging,till 70% charging is smooth and fast...pls help me to troubleshoot this thing plzzzz... :crying:
sounds like you might need a new battery
Yes, you need a new one.
Most batteries from more than a year ago starting to have this problem after updating to 6.0.1
The update stress the battery too much and if your battery is more than a year old, will likely be damaged after that stress.
Yes, samsung batteries are less than cr*p.
