I've had my SGS2 for quite some time and never really had issues until recently I suddenly started seeing 'drive mode' appearing on the top left corner of the screen - the phone behaved erratically in that whatever I was trying to do, drive mode and vlingo would keep popping up. At the same time this started to cause the battery life to drain rapidly - on a full charge and in flight mode the battery lasts about 7-8 hours, before this I'd get more than a day easily on sensible use - there's also the issue of the back of the phone feeling abnormally warm (which i think is causing the battery life to drain). The phone also doesn't get picked up as a storage device on pc, if i charge it i get various issues like voltage being too high or the battery icon showing a warning triangle and sometimes the battery icon is flashing. I've also tried a factory reset - to no avail. Has this happened to anyone? if so what did you do to get it fixed? Some times when i swithoff my phone, the phone will automaticaly restart. Even in swith off mode also the battery charging symbol is coming. And i had put my screen light to 15 seconds after inactivity.. Bt it is not getting off.If I check the battery details it is showing 79 or 80% for screen... Can anyone tell me the reason?????? How can I solve this problem?????

i am having a quite unusual problem with the battery on my TP. it is hard to explain but i will try my best to do so. While i was casually surfing the web while on the charger i noticed that my battery started to drain ( this is the more ordinary problem that has been posted on many threads ) but this new situation is. The indicator lights and meters within the TP indicate that the battery is charging yet it still drains. I tried turning it completely off and removing the battery and then putting it back in and charge the unit for one hour. After one hour it charged to 20% which is reasonable enough for normal use, so i turn it back on and continue to use the device again the TP still indicates that the battery is charging after listening to about 7 songs i get a very low battery indicator warning (at the same time the battery indicates its charging) there is NO overheating and when the battery reaches 0% it does not die the screen just goes off and i can turn it back on and still recieve the low battery warning but what i cannot do is use data or even turn the phone radio back on. I am on the NFS 1.05 ROM, any suggestions?

Try to get a charger with an output of at least 1 A. It could be that your charger is not powerful enough to compensate for the drainage. The other thing is that WM' battery indicator flat out sucks... it is like Windows file system when it is desperately trying to tell you how much time you have left before your task is done (2 minutes jumping to 15 seconds jumping to 54 minutes jumping to 2 seconds jumping to 3 days, etc)..
Flash to another rom and see if the behavior still remains.... I doubt NFS messed up that badly with power settings, but it is always worth giving it a shot.
yea i doubt its the rom either as i was having overheating/drainage problems on stock but it wasnt anything like this
OK, so here's the deal:
Had my S2 for about a month now, and apart from the battery draining faster then would be nice this phone is an absolute killer cool thing
But now here is the issue:
In the month I had this phone I had 3 occasions of the battery draining to empty while it is ON the original wall-charger. Do describe the most recent case:
Im at work, and I see the battery could use some charging soon. So I plug it in, leave it for a bit with screen turned off. A bit later I pick it up whilst still in charger to do some minour things on it. After a few minutes (phone very hot in mean time, but known issue) it gives me a pop-up that I need to plug in the charger which it is already on. So I check my Juice Plotter and notice that indeed it sees it is on the charger, but the line which shows you the level your battery is charged is coloured red and has been dropping just as fast as before I plugged it in. Near critically empty?
So to check if some app is draining the juice in the background i closes all running services and apps and leave it for a moment. I check: only about 1 percent charge left? O - M - G.
So i did what I did in previous 2 cases: Turn phone off to get it charged to at least about 20% (how nice that someone/something else is forcing me to be unreachable by phone ). When I turn it back on at that point, I check juiceplotter first... No real changes or battery charging for first maybe 5 minutes (it just stays at a flatline level) and then finally it starts charging again slowly but steadily.
What's the deal here?
Since 1st time this happened i started keeping my home screen as clean as possible and such to be as energy-efficient as possible. Barely use screen-brightness (by the way the auto-brightness sucks). On 1st page of homescreen I have the Juice plotter widget showing me battery depletion / battery charge time levels. Funny that in the explained problem cases you can actually see the time till charged getting longer and longer by the minute :S
I've been messing with my phone all night, setting up screens and what not and it just died. I plugged it into the charger and nothing for a few minutes and then the LED turned on and was white. It wouldn't start or go into charging mode. I removed the battery several times and left it out for several minutes. After leaving it plugged in for a few minutes, the LED turned green but still no startup or charging mode. After several more minutes, it finally went into charge mode and the LED turned orange and was 0%! Another 10 minutes and it was 15% and booted fine. I would think I should get warnings and if ignored, the phone would shutdown before completely draining the battery. Is there a setting somewhere I don't know about?
I don't know about any warnings...there is a battery icon on the upper right that I'd think would be fairly hard to miss? Red means charge asap. But if its completely dead, once you plug it in you have to wait a few mins for a charge to build up before you can turn it on.

Edit-
*actually just got a popup message saying i have 15% battery left.
I had an issue once where my photon got stuck at 80% and ended up dying with no error message because it wasn't reading the battery properly. I was able to see in the battery usage after I got it back on that it plateaued at 80% for quite a while. I haven't had the issue since then, but maybe you had something similar happen.

My battery indicator was stuck at 50% so it does sound like the same issue. I thought to myself "wow the battery life is much better than I thought". Guess some things are too good to be true.
Just for the record, I had a similar problem. My phone was reporting a charge of 100% but then I took out the battery, waited half a minute, and when I put it back it the phone said it only had 5% and had to charge it all the way back up!
Download Battery Monitor and put the widget on the home screen. See if its just the icon not updating or something more. I did notice once when it dropped "suddenly" but has not happened since.

I've had this for a while and used it quite a bit. I just noticed it can put the battery percentage in the notification bar and you can tell it to ignore the battery level the phone tells it and to calculate the battery to the nearest 1%! No more guessing what the actual battery level is!!!
Recently I noticed that my EVO 3D is showing an exclamation mark over the battery icon. Then weird things begin to happen, After charging the battery to 100% and unplugged the power, 1hour later my battery has only 40% left (i've turned off all automatic updates except for weather update and wasn't using the phone at all) . The other time i noticed was when I plugged my phone to the car charger, the phone instantly powered off. After switching it back on, the phone battery had only 8% left, and before charging the battery it was 65%.
What can I do? please suggest. thank you

Seems there is some issue with power.
Off the top of my head, there are three factors: battery, hardware power management and software power management.
I would first start testing the battery as those seem to go bad quicker and more commonly than the power supply/charging units inside the device.
If a known good battery has the same issues, might be something wrong with the power management hardware inside the device.
In order to eliminate a software issue, load a stock ROM on the device as this should have normal/standard performance.
Addressed all three really briefly, but I think those steps are the most ideal to gain the best results. Hope that helps!
Hello everyone, I'm new here on XDA, so i hope this is in the right place. I have a problem with an old i9100 that i recently got as a gift.
The phone was given to me without battery, so i bought one and immediatly installed Lineage 14.1 nightly (latest build, 13th dec). Then i started to notice that the phone would go off and the battery would drain to 0% unexpectedly. The phone works fine until the battery reaches a level of about 50%. Then the phone suddenly shuts down (sometimes i was able to see the screen flicker right before it happened). So i got the battery replaced, however the simptoms remain.
After regularly checking /sys/class/power_supply/battery/current_voltage i found out that the battery is mostly stable on 3.7-3.9v for an hour and a half until the 60%-50% threshold is passed in the battery indicator on the status bar. Then it rapidly drops the voltage down to 3.4/3.3v in a couple of minutes, where the phone shuts off. I have already tried to clear the cache and reset the battery stats through rootEssentials.
I was unable to find something meaningful in catlog's output. The moment of shutdown is around 22:13 and next boot is 14:19 (i left the phone with the battery off during the night). The log suddenly stops and starts again as if nothing had happened.
is it possible that i got two faulty batteries, is it a software problem or should i be taking it to a repair shop?
Thank you in advance for your help!
