Hi Friends,
I noticed my Battery discharges when phone is OFF appr. 2-3% per hour! I supposed the battery was short circuited itself.
I opened the phone and disconnected the battery. I left it for a day and IT DID NOT discharge! It was at the same level when I reconnected and checked.
So my phone consumes energy when it's switched totally off. In 2 days it drains from 100% to zero.
Did any of you experience such issue? Any advice, please! Thanks!
i have similar problem on old G901F - when i shut down phone, offficial software!, it drains battery to zero in about a week. when battery is out it does not drain. I think its a hardware fault, power section is damaged?
It's a pre-owned phone, I don't know its history. But today I found the water indicators at the sim tray was triggered.
I suppose the battery drain issue might be a result of the water damage. (?)
Your device should only discharge a very, very small amount at a time when it is off. As that is your device keeping the time on your device's internal clock.

Well, this is not an issue, but i discover yesterday.
My battery performs well, as good as in my Hermes. I need to charge every night, cause i have BT active all the time, and push mail over 3G.
Yesterday the battery was at 70% charge. I take out the battery, and after one minute, i put on again. Switch on the PDA and the battery says 72%.
I test again, with 40%, and same result. Take out the battery makes 2-3% higher charge.
This takes me to think the method Kaiser calculate the battery remainig is not so fine. Is true that is better that Hermes, but perhaps the battery temperature causes the driver to show incorrect values.
So think you have 2-3% more battery that the value it shows.
Anyone can verify this in his Kaiser and post the gained battery?
Cheers.
I think the reality is that trying to gauge battery life of a Li-Poly battery down a single percentage point is simply difficult. Their voltage drop is not very steep, so the voltage differential between 70% and 73% is not going to be very much. On top of that, it is very common for batteries to gain a little voltage if left without load for a bit. You can see it with a flashlight... run it down until it's essentially dead, then turn it off for a bit. When you turn it back on, it suddenly has some life left that didn't appear to be there before.
I test with 83%. Take out the battery makes 87%.
I'm worrying about my battery. The main thing is, it drains really fast. In flight mode and nothing else on it drains like 2% each hour. So overnight, most of the time it drains like 16%. Today i started with 100% in the morning. Used GPS for 1 hour, made a phonecall for 20mins in total time. My battery indicator said there was 30% left :/ I know this thing eats batteries, but this is insane. Because i noticed an incorrect display of the battery the last few days i gave it a soft reset. After the reset i saw the battery had only 4% left, not even 30%, but 4! :|
Many times when the phone is saying i have 'insert number' percentage of battery left it's incorrect. Because when i give it a soft reset, it changes the number. Sometimes i get more percentage back, and sometimes it drops.
One hour ago i plugged it on the charger, checked 45min ago, and it was still on 31% battery :| Then, like 10min later i suddenly saw a green light from my phone and it was full.
I've never had a device with a broken battery and i don't know the symptoms, but is this normal or is it likely that my battery is dying?
A little kick!
Hi everyone, well when i charge my battery all the way to 100% its fine, i use the device as an mp3 player as well which in my case brings down the battery 10%, but most of the time my battery meter is not accurate, for example it will say 54 percent but when i restart the phone it will shoot up to 75 or something, it always does that, is there any hardware problems or anything?
Battery Trouble
Hello MimoG3
This may or may not be related, but I remember after restoring from a backup a few months ago and removing the battery prior to this the device battery meter was very inaccurate. After the restore, the battery extremely low warning came up because it thought I had 0% battery. Long story short, after a while I noticed the battery was not seated properly. So I took out the battery, cleaned the contacts, and put it back in, and it worked fine again. Try cleaning all the battery contacts. Google "Clean battery contacts" or something similar if you do not know how to safely clean battery contacts.
Also, although I have not had this problem that your are describing, try posting your rom and rom version, radio, device information, battery s/n if possible, and other device info should it turn out there is a bad batch of batteries or devices.

i have noticed when i restart the phone once in a while and when the battery is fully charged it will think its empty and shut off the phone, to fix that i take out the battery and it starts up again. also sometimes it freezes at startup until i take out the battery but that happens when i restart as well.
Leave your phone on playing music until it turns itself off because of low battery. Remove battery 10 seconds, put it back in and turn on again. Repeat until the battery is really empty and the phone turns off less than 5 mins after you turned it on. Plug charger, turn on, leave until fully charged. This should improve accuracy. Avoid removing the battery if not needed.
ive done something similar to that, i turned on the wifi, bluetooth and gps on so that it would drain the battery fast, then when it turned off i turned it on again with all those things off except the GSM Radio, then eventually it shut off once it stopped turning on i charged it all the way. it still didnt help
battery measuring is not really that much of an exact science
only way to tell the % is
when a batt being pulled current from the volts drop
the less juice left in the batt the more it drops
so the device measure the volts
and makes an educated guess how much juice is left
just after a reset the batt could very well perform a bit better
for a few mins voltWise

Did you remove the battery? The phone doesn't usually reset the meter if you leave it in.
@rudegar: No, most recent devices including HTC phones don't only use the battery voltage but count how much energy they use / charge to the battery. That usually allows more precise measurement, but can also sceww up if uncalibrated, and is really annoying as it doesn't want to use higher capacity batteries correctly.
During the night, my Sony Xperia SP was charging. I began charging at 1:30am and i fell asleep after that. I woke up at around 8:20am and pressed the power button to turn on the screen. It did not turn on, and then i noticed the phone was turned off. I powered it on and the battery was at 100%, however i thought it was strange that the phone was turned off because i had left it on overnight. I checked my battery stats on Battery Widget Reborn (The Android battery stats, GSam and Better battery stats showed no data because it was all erased as the phone turned off) and found out that my phone had completely, after being fully charged, drained 100% of battery in just a few minutes. This is the first time it had happened, and i had bought this phone only about 2 months ago. I had not left any processes/apps running, even so, the battery should not have been draining this quickly. The drain from 100% happened from about 4:18am until 4:20am.
What would have been the cause of this battery drain?
Has this ever happened to your phone, and is this problem unique to Sony Xperia phones? I have heard that Sony phones have very bad battery optimisation and battery life.

First of all, sony phones have great battery lifes. I know that because of my experience with xperia phones (mine and friends' ones, too). Personally, I passed through an xperia tipo and now I have an sp, so they DO have great battery lifes. As for your problem, I think it's the battery stats that cause it. If you'd be able to take off the battery (youtube might have such tutorials) for at least 10-15 seconds and put it back on, it may solve the problem (taking off the battery for such a time is similar to "wipe battery stats" command in recoveries). Alternatively, you can install a recovery (e.g. c.w.m.) and wipe the battery stats. If the battery keeps draining like crazy, I'm afraid it's time you went your phone to a service center so they'll replace it with a new one.
I have been experiencing this problem for 2-3 months. I charge my phone to 100% and when i reboot my phone (for some other purpose) battery level drops to 40 or 60% and this is extremely annoying. Usually when this happens i shut down my phone pull the battery out and put it back. After powering on the battery level is back to the correct value. But now it is not working. The battery level stays there and decreases. Well it only happens sometimes but still when i need my device it is low on battery.
I searched on the internet but most people using galaxy s2 were facing this and they recommend doing a battery calibration which i didnt find useful.
Any solution?
I have uploaded the battery usage in case it is needed.
