Looking for advice regarding my battery life after 4.2.2. - Nexus 7 Q&A, Help & Troubleshooting

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.

Having the same problem.
Didn't even make it to work and was below 50%. Weird.

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.

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....

It is definately the android system. There is another thread here where the samsung rep says they know about this version of android and the battery issue. My tab went to zero yesterday in ten seconds. It took me a long time to get the battery meter to show it was charging again.

Has anyone tried calibrating the battery? I just received a Tab for testing and it was used prior. Some battery monitor apps reported less then 12hours available after a full charge. After I calibrated it, i'm getting ~28 hours / moderate use before battery is depleted. What amazes me with the Tab is that when idle (overnight) there is no decrease in battery levels and graphing shows a complete flat line when idle.
I love this device

I have done all of the battery recalibrations suggested here on xda to no avail. The only thing that has helped me is plugging in a portable kennsington battery by usb that tricks the battery indicator and it seems to slow down my battery drain.
Said at all, i have to get use to with it, right???

Try doing a resetting on the tab, and do a full charge, I mean let it charge for 8 hrs continuously.
If it can't work, bring it to Samsung for firmware upgrade (takes about an hour), after which do the same, long charging.
Last option, ask for an exchange with Samsung.
Rooting it has never been my option

Hey guys, I was in the same boat (you can see my posts on other threads) and I have tried pretty much everything from flashing rom, resetting, calibrating, and bump charging. Last night I decided to open up the tab and look at the battery, thinking maybe I should buy a new battery to test.
Long story short, I disconnected the battery from the board and let it sit for 15mins before reconnecting. I check every couple hours to see the battery level in android. So far, I only lost 1% for 20hrs in flight mode w/o any app running. I usually lost 20% overnight and would regain that after reboot. So the problem is GONE and the system is reporting the right battery percentage without fake dropping.
I will continue to monitor it and report back, but it looks great so far. Hope this helps other XDA fellows.
Thats actually ive been wanting to do just prick it open, funny though i my problem resolved it self, last night i keep rebooting my tab up to the point it hangs and froze then i left it like that for an hour then i pressed the power button for around 10 seconds to reboot it again, once it booted up it showed the correct percentage, now im still monitoring if the trick went well..

Hi Shinji, it is quite unbelievable that the tab only drain 1% for "20hrs". But it is great, if opening the tab can solve battery issue. Now, I myself encounter some other new problems, after I solved the sudden drop in battery issue by upgrading to new firmware (e.g. 50% => ask me to shut down). Now, no matter how I charge, it will remain 67 or 70%............
Do you have the instruction to open up the tab, or any link which you can lead me too? Thanks.
Hey henrylam do you charge phone whilst on and how long do you charge for before you get fed up waiting for it to move from 70% and remove charger ?

I try both, on and off, sometimes it work sometimes it doesn't. After I have done factory reset, it seems ok for first 3 cycles. After that, the problem surfaced again.
Sometimes, it just stop charging at 65 (curvefish battery indicates) but battery icon shows like 85%. I felt like smashing the Tab and get myself a new Ipad. I am thinking to send it again to Samsung this Friday, and let them investigate for a while (hopefully 2 weeks will be sufficient). Damn it, my wife tab has no such issues. She didn't even do an upgrade on her firmware.

Weird Battery Behavior. Any solution? Or time for an RMA?

I have had this phone for about 2 months now and everything has been exceptional with the phone. Have seen people complain about the battery life, however it has been really good as far as my experience is concerned. However since a week I have seen the battery screwing up a lot... A LOT.
I always used to charge my phone daily in night. Plug it in..set an alarm of 3.5 hours (yes it takes 3.5 hours to fully charge from less than 10% stage) wake up..turn charging off..sleep back. Okay, some of u might think it is stupid but can’t risk of leaving it on charge the whole night and burn my phone. Anyhow, so, since a week what I do is I charge my phone whenever I want (read it on a few thread and articles)..be it 50%... 80% or even 92%. I just make sure its 100% whenever I leave home.
But something weird has started happening... The battery percentage keeps on changing.. For instance:
when I unplug it..its 100%.. within minutes of usage it drops to 99..then 98.. then 97 and suddenly it rises back to 100%. (Pics attached)
Sometimes when its on charge and I come to check SMSz and reply them.. battery % suddenly drops.. e.g: if its at 99%... it will suddenly change to 96% in a second and in a minute goes back to 99% .. so on and so forth. And sometimes even when its charging..if it is at 80%, it will suddenly shoot up to 100%. The percentage doesn’t change even after a reboot. Weird, isn’t it?
Now the most weird issue, since yesterday the battery life and dropped to 50% less. I used to get 4 hours OST and now I hardly get 2 hours. During night, the battery used to drop 2% in about 6 to 7 hours and yesterday it dropped 15%. There was this one time when it dropped 9% in 6.5 hours (pics attached). Tried seeing through Wale Lock Detector but there were no Awakes during deep sleep. Too weird :s
I don’t really know where did I phuck up as I haven’t installed any shaddy apps or something. Please advice.
My phone info:
All stock. No root (and not looking). No custom Roms whatsoever.
TL;DR... Battery acts weirdly. Shows inconsistent percentages. Suddenly shoots up. Suddenly Drops. And now the On Screen Time has reduced 50%.
It sounds like it's nothing more than a bug.

Thanks for ur reply. How to figure it out? And measures should be taken? Any suggestions?
this has really kept me worried since a few days.
This is "normal" for the N4, and the most/all of them do it. Unreliable drivers, or a hardware fault, not sure.
Here are other threads about the various battery bugs, but there are many more:

I know I searched many threads before posting and mostly had the Shooting up issue only, when charging.
Anyhow, this normal behavior has reduced my battery life a lot.. which I am not liking .. What to do?

Both my N4's (different H/W revisions) have been doing the 100 to 98 to 100 thing as well since new. Battery life is still excellent for me. An RMA would probably do the same.
Happens with my nexus 4 too. But this hasn't reduced my battery life at all...

You're pretty much stuck with that phone as you only have 15 days to RMA a device, your only option would be to send it into LG for a repair. My battery has acted up like this once so I stopped using the stock charger and it hasn't happened since.

Rebooting might help. Could also be an app that updated that now doesn't play nice. You could try a factory reset just to clear out some crap but I'd back everything up just in case first. Not sure if a factory reset deletes all your user data in memory or not. I only did it once right after I got the phone so can't remember. Hate to lose all your pictures, files, etc. that aren't backed up.

It's normal. The N4 isn't great about showing the exact battery life. In fact, what you see isn't the true percentage, it's an estimation. Don't worry too much about it!

This is a question I can't answer along with any facts. I tried disabling it for 2 days and I noticed the OST reduced from 4 hours to 3.xx hours. May its placebo or something but then I enabled it...thinking if it's not doing any good then it's not doing any harm either.

Hmmm, I didn't know that. But why is that? Any apps or something to show the exact battery percentage left?
Happens to me once in awhile. Do a quick reboot, and if that fixes it, I would not worry too much.
Hmmm..
Yesterday when I woke up in morning.. the battery lost 2% only in 6 hours. I felt SOOOO relieved that my "good battery" is back. But who knew what was to come... today I woke up after 7 hours and the battery lost 15% .
My usage is always the same. I force close all the apps I use daily and turn wifi etc all off. So i doubt if its any app.

Very Strange Battery Stats - Help Appreciated

I've just flashed PA latest build (dirty) and my battery stats are pretty messed up, apparently Bluetooth was the biggest drain on my phone, 57%, and it was on for nearly 50 days.
I don't use Bluetooth and obviously a battery lasting 50 days is nonsense.
I've had a search and found people experiencing high drain from some services, or reporting 100% charge as soon as plugged in, but can't find anything resembling my problem.
Is there a way of resetting these stats without having to do a full wipe. I tried charging to 100% but they remain.
get battery calibration app, should delete the stats shouldnt it?

Thanks for replies. I did a charge last night but the stats remain. I probably didn't charge to 100% just almost 100%.
I find that it can take up to 30 minutes to go from 99% to 100%. I will leave it charging overnight and hopefully that will sort it
That Bluetooth figure just seems weird, and I have no idea where it came from??

[Q] Nexus 4 Battery drops

Having some really strange problems with my Nexus 4 battery. Sometimes my phone will completely drop out at a reasonable percentage, and be completely dead. Now lately, my phone will say 100% but after a reboot, it will say something like 50%.
I loved this phone but somehow after the OTA 4.3 update things started getting seriously messed up.
A lot of times I have Android System, and Android OS (and sometimes mediaserver as well) as leading battery drainers.
I don't understand what is going on with my phone. To fix this I rooted and flashed over Sentinel Rom because it was noted for good battery life.
But the problems from before still persist.
Here are some screenshots of what I'm finding. Please any help would be nice.
My last guess would be this is something hardware related. Could this be a battery issue? Or a wire issue?
I have opened my Nexus 4 previously.
This is driving me ballistic. I love this phone but it needs to last me a bit longer.
Thanks for all your help, lets get this fixed!!
There are some users reporting same behavior and that replacing the buttery fixed their issue.

[Q] Fault battery indicator [SOLVED]

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?

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:
As happened to the N10, after a while the display appear in the stats:

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.

I don't think it'd be the 2A charge, I use the 2A charger on my battery all the time.

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).

Unfortunately, no. Probably it is a battery related problem, i'm going to replace it and see what happen. In the meantime not even PurityROM+HellsCore kernel may handle this battery draining...
