Hey guys,I have seen some things with my GS2's battery that aren't exactly what you'd call normal.Let me explain:
Today,I plugged my phone it at about 45% battery for some minutes(I was gonna be away from home for a long time,so I wanted some extra unneeded juice) and unplugged it just before I left the house at 58%.I was en route to the bus station when I checked the time(I was late as always! ) to see I had 59% battery.After some twenty minutes,when I reached my destination,I took my phone out of my pocket to make a call just to see that my battery was at 61%! After that all was normal.
This was the third time I experienced something like that.First time was more impressive.I went to the cinema with 38% battery and left with 50%!All without plugging the phone anywhere!
Now,I know I shouldn't be complaining about something like that,but something must be wrong here.If everything wrong was like that I'd be a happier man,but just sayin'.
Any ideas?Or is my phone unique in that aspect?
Sounds like bad calibration to me. Let the battery drain till the phone turns itself off, then charge it (while off) till full.

Me wants . With that said its probably bad calibration

Definitely calibration problems here. The screenshot below explains what happened with my SGS2. This was the first charge out of the box. Plugged it in and at first, the charge went up steadily. Then, BOOM, 100%. Disconnected charger, and after some time noticed phone was off - battery was at 0% in under 2 minutes.
It's OK now. I'm getting 2+ days of use on a single charge.
same here. my battery-percentage also raised once while using the unplugged phone. then I turned it off and charged it. since then everything is fine.
Too bad.I thought I was like the guy from Infamous or something!
Thanks for your replies guys.Will callibrate and report.Although the Android OS drainage persists still...

The charge level on my SGS2 is going up as I am typing this. It is not connected to anything.

For the love of god i can't understand why my Nexus 4 battery is draining while it's off! Sometimes i use my iphone 5 , and always charge the Nexus 4 in case i wanna use it,i know it's already charge. 2 days ago i let the Nexus 4 completely charge, today i power up the phone and the battery was at 14%. It happened a couple times but was always thought ah maybe i left it on or something, this time i made sure the phone was off, but battery still drains... Im on stock rom never rooted, using Nexus 7 charger... Any idea on what could be the problem?? Thx in advance!

I mean i don't have battery problem at all when i'm using it.... It's just when the phone is not in use and off it's still drains battery like it was on... I can understand something like that happening if the phone was off for a long period of time but 2 days 14% left while off seems ridiculous!

Try using the same cable and charger. Make sure Facebook isn't running or any apps that can drain your battery. Facebook killed my battery with no data connection

I just sent my first Nexus 4 in for RMA on this very issue, got the replacement on Friday, did a charge cycle, charged the phone fully up whilst off, took it off the charger (the official Nexus charger btw), and let it sit for the last day, just turned it on, and it's at 60%.... W T F !!!
This is sooo totally bizarre! I can only assume that this is common to most Nexus 4 (what are the odds of me getting two bad ones - direct from Google - with the exact the same issue?), and that people just aren't noticing, as most people don't leave their phones off after fully charging, and thus just never notice, as the battery behaves perfectly normally under usual use.
I would gratefully appreciate it if people could put this to the test, so I know whether or not to RMA the second device or not....
Was the phone powered down, or just sleeping? Any programs set to auto sync? Check for wakelocks?

Hey I've searched for help on the subject all over and. I'm not seeing anyone with this problem, on the contrary everyone seems to be doing better.
Anyway I got the OTA update to 4.2.2 from the. General forum a few days ago and flashed it without much consequence and everything seemed fine. I reaquired my root but I have noticed my battery is losing charge way too fast doing light browsing and use.
Checking battery use I got 2 hours of screen time with 30% of the battery and again this has been simply browsing sites with pure text. As I'm writing this it went from 70% to 68%
To list a few key things that have happened that might be important and I'm hoping anybody can help or give advice.
1) I stupidly forgot to wipe cache and dalvik before and after flashing the update, when I remembered I went to recovery and did this
2) I rerooted
3) On Friday I fell asleep using it and when I woke up it was completely drained, honestly I don't even remembered what I was doing cause I had a bit too much wine but I think I was playing an emulator and when I woke up it wouldn't even turn on so I charged it back to 100%
As I write this now I think back and problem seems to have started then.
I tried re flashing a backup, which didn't help and I flashed franco kernel reading it gave good battery.
My last idea is simply reverting back to stock and see if it helps but before that I wanted to check some opinions or advice here.
PS I have already used BBS and its finding nothing wrong in wakelocks or use (except something called AudioOut2)
As I finish this im down to 66%, definitely not normal.
Any help is appreciated.

Didn't even make it to work and was below 50%. Weird.
Sent from my Nexus 7 using xda app-developers app
Did you at some point let it drain completely to 0% after updating to 4.2.2?
If nobody has any idea ill just go back to stock and report results.
Sent from my Nexus 7 using Tapatalk HD
Well if anybody has a similar issue or cares, going back to stock seems to have fixed the issue. Regardless I did some light testing on the battery. It shows marginal better perfomance on 4.2.2
By switching Kernel there was no change it seems but then again the test only covered two activities perhaps with further comparissons better results would be gotten.
But long story short if anybody has this problem apparently going back to stock is the way to go.
I'll keep a careful eye on the battery and gauge on regular use and if it happens again have a better idea of what caused it.
Its a program that's running or not completely shutting down.
Torrent was my issue. Uninstalled rebooted and then reinstalled.
My battery life is good now.all day and still over 80%.

Well I have encountered a completely new problem lately.
In the last week this has happened 3-4 times. I leave it charging or simply on deep sleep for a while and when I try to turn it on it won't, I'm not sure if its shutting down since when I plugged it in (thinking battery had drained) not battery charging animation came up, instead I left the power button pressed and it came up with whatever charge it had.
Not sure if its a side effect of the original problem of the battery discharge or something to do with torrent clients as 3 of the total times it has happened I was downloading something and left it running.
Not sure what to do at this point since I find no info on this or it happening to anybody else. What I find are things like it not charging etc which really arent my issues.
I will avoid using torrents on it for a few days and see if it happens again, if it does I will seriously have to consider contacting Google or Asus since this device doesn't even have 90 days in my possession yet.
If anyone is following this (really just posting here to help anybody who finds the same problem and as a sort of journal) I found this post on the kernel im running thread
http://forum.xda-developers.com/showpost.php?p=38422891&postcount=4603
Somebody replied to that post stating its a 4.2.x problem
It could also be a kernel problem with torrents as further down the posts another person complains about the same happening when using a bittorrent client
I'll post with whatever I find out.
I've been having the same problem glad to see it isn't just me.

Hi Chaps, Since my upgrade to 4.2.2 I thought the battery life was great. It stayed at 100% for ages and when I was streaming music for a few of hours and the battery only went to 96%. Superb I thought..
But, yes there is a but. My N7 now shuts down when the battery is at 32% and I need to charge it to get it to reboot as it is well drained. Is it possible to zero the battery indicator or recalibrate it for an accurate reading? TATA R.

Battery calibration, which should be done rarely, is merely a matter of putting your device through one complete charge/discharge cycle. Don't waste your time with battery calibration apps, as they are 100% snake oil. Likewise, you can disregard any misinformation about wiping battery stats, as that has absolutely no bearing on battery charge indication.
Try unplugging your battery for a few minutes, and then plug it back in, ensuring that the connector is firmly seated.
Getting pissed off here. N7 shuts down at 42% now. WTF. Is this a 4.2.2 problem? If so how do I revert back to an earlier version?

I am seeing reduced battery life on 4.2.2...
I used to be able to go all day on a charge. Now I can't make it through the evening ...
I know that is subjective as I didn't indicate my prior usage compared to my current usage pattern.
But my perception is that battery life has degraded ...
As an aside, I noticed that an el-cheapo IKEA power strip didn't provide enough juice to keep the battery from draining further while using it when plugged in...
It plugged in at 20% and kept using the N7... awhile later I was in the mid-teens.
I don't use that power strip any longer....

Hello, :fingers-crossed:
i'm having a lot of troubles with the battery of my Nexus 4. I'll try to explain this strange situation...
Few days ago i noticed a ridicoulous battery drain while i was, as usually, listening to some music with my bluetooth A2DP headset Jabra HALO2. It was something like 1% every less then 1 minute. At first i thought it was due to a recently upgrade to CM10.2M1 (which is a monthly build of Cyanogenmod on 4.3) or due to a 5 minutes fast charge from the 2A charger of Nexus 10 that could have "upset" the battery.
At first i started focusing on the software side problem; i tried CM10.2RC1, CM10.2, stock 4.3, stock 4.4 and now CM11M1, and, while doing all of those wipes, i noticed that not only the discharge was insanely fast, but even the charge! The graph on the setting panel is almost vertical while cahrging, like 3% to 40% in 25 minutes.
But that's not all, sometimes, after rebooting, i noticed a battery level different from the previous boot, so i decided to wait a full discharge and then fully recharge it. I have waited the 0% (not so much time ) putting the screen always on and the LED flash too, then, i tried few times to turn it on and every time, after the boot screen disappeared it immediately started to turning off due to 0% battery.
Moreover, for being certain, i tried to turn it on in recovery and wait how much time it would take to consume the lasting charge on the battery. Surprisingly, after 30 minutes it was still there! I tried a reboot into system, showing me a 10% remaining battery (WTF), which discharged to 0% in like 3 minutes. Now i'm waiting the whole night the real discharge in recovery with screen always on, hoping that a full recharge could fix it. I would like to evidence that the phone do not overheat during both charghe and discharge, so i guess the battery itself may be ok.
I'm still not sure if it's a software problem, and i'm worrid if it could be an hardware related issue. Maybe it could have been the charge from the 2A adapter.
I really don't know what to do next. Someone knows how to help me?

EDIT:
I've done a full discharge until even the full hybernation has been shutted down, but seems that it hasn't solved anything. I've also noticed that in the battery stat is missing the display consumption (WTF?!?). Maybe it's a CM11M1 bug, it happen even to my Nexus 10. Here other shots:

EDIT:
I've noticed just now that while I was waiting a real full discharge of the battery the TWRP couldn't show me the battery percentage. Really strange...
[SOLVED]
In summary, the problem was the combination of kernel+ROM. The CM with his kernel on N4 was consuming tons of electrons. I tried Purity+Hellscore, now i reach few days of low usage and one and half of medium usage
How old is your phone? You might be able to get a replacement from Google under warranty.

It have 9 months, and yes is still under warrenty, but I've bought it in Spain, and I live in Italy. I think this will be hard to solve
I have some strange problemi too.
Sometines the phone reboot itself and the battery drops (i tried to flash all stock: recovery, bootloader,ROM ecc..)
It could be a faulty battery.. Read this topic, it looks like you have the same kind of problems.
Do you also have simlocks/loss of network connection?

I've already read this topic, i think the source of the problem may be related with mine, but symptoms are different. It is strange that this happened 9 months later!
Gully discharging the phone, rebooting, discharge again if any, reboot. Connect charger, charge full. Reboot, charge full again if any, reboot. This always worked for me.
You can also try to fully discharge, completely power off the phone and let it fully charge while powered off ( only a white battery should be shown on the display).

Hi all!
I've some strange problems with mt nexus 4 battery values.
Today i had 59% of battery and i plug it to the original charger. After 2 hours i saw the battery with 100% charge value. OK. Nothing wrong here. I rebooted the phone and after that i had 84% of battery.
This is happening almost every time i charge my nexus 4.
I had stock rom with franco.kernel updater. Now i have paranoid Android with The same kernel.
Any idea about this?

Have you been dirty flashing a lot?
your battery reading needs to be recalibrated.... Charge full than use until it shuts down...than charge again fully, at 100% reboot phone & connect to charge again.....
You also can try "BatteryRepair.apk" from market..most of the time it helps to recalibrate..just install, open & follow on screen instruction....

I had the same issue with my previous nexus 4. Did you ever get your screen/display changed? Or do you charge your phone overnight? Do you rely on USB charging a lot? If any of those answers is YES, its probable that your battery has gone bad (as mine had)
I don't think that's the solution, but give a try to this free app from the play store: https://play.google.com/store/apps/details?id=com.nema.batterycalibration&hl=it
I always thought this problem was related to rom development but I'm not sure. It happened to me with CM11 at the very beginning in november, and then it just stopped. Since January I'm on slimkat, at first it didn't happen and then for a few weeks i noticed the same problem you have, now everything has been fine again for the last two weeks.

I've tried the calibration 2 days in a row (battery at 0%, then charge till 100%, reboot, charge till 100% again). Yesterday i had 90% after the reboot. Today i got 91% after the reboot.

I'm gonna try that app. I rebooted the phone around 9am and now is almost finishing the charge. The battery lasts till tomorrow with my normal use of the phone, but i tough strange that every time i rebooted the phone, i lose battery % :s
Just try avoiding the charge to 100%->reboot->charge to 100% again for a few days.
Don't let it discharge till 0%, connect the charge when you have 1%-4% left and let it charge till 100% with the phone on, and then use your phone normally.

Please go through this thread. A couple of other members (myself included) finally deduced that if you ever have your display changed you NEED to get your battery changed as well. Trust me on this, get your battery checked once. It WILL be bloated. Also, if upon restarting there is a break in the battery graph and there is a significant drop/rise in battery level, that is another indicator that your battery is going.

I've been reading that thread but for example, what happens to me it's nothing compared to the first topic of that thread. I only miss sometimes 10% after restart, sometimes 5%, sometimes nothing. From what i understand, in that thread most of users with battery problem had like 80% and after reboot they only had 2%, or 0%. Thats different i think, but i'm not expert on this subject
Anyway, installed the suggested app and calibrated the battery throw the app. For now i have this data (Paranoid Android Beta6+Franco.Kernel.Updater r201):

Try Battery Monitor Widget from the Market - you can see what current the phone is pulling, and if indeed full charge is reached. There are also calibration tools inside - the app calculates the real capacity of the battery, for example. If it's a long way from 2100mAh it would be a sign you need a new battery.
Though like everyone else, I think it´s a software problem. With previous Android phones I had to be careful calibrating, flashing etc. With the N4 I've had no such issues in the year I've had it. That app can help you sort out battery calibration though.
Can you tell me The dev name? Got 2 battery monitor widgets :s

This looks normal, although if you see a break in the battery graph and huge drop/rise in battery then its definitely done for. However its not the case with your phone, so relax
Well this evening i left the phone with 60% of battery and at 7am the battery was death. Just ordered a new one. I've only one problem. I dont have any plastic screw to open it. I've the torx t5 screw only.
Any advise to the new battery?
