Weird battery quirk - Nexus 4 Q&A, Help & Troubleshooting

Can somebody explain this? I'm on faux kernel. This has happened to me a few times both on 4.2.2 and 4.3.

Same thing is happening to me using Franco. I have noticed that my battery kind of increased its size, so I think it might be a battery problem. I also expect some error when battery is low, like completely lose signal (due to low voltage maybe?). Just ordered a new battery today, will wait till it arrives the check if its really the battery.
I don't know why it shows bad signal as my phone was always in airplane mode but I think its just like your problem.

Battery drain while phone is off

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!

Maybe a bad battery?

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?

Did you use the same charger with both phones?

Looking for advice regarding my battery life after 4.2.2.

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.
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....

Worst battery life ever

So, I've been using my Nexus 4 for several months, but in the last one I'm having really bad battey life. The OS is always active as you can see in the screenshots below; any advice?
Battery life is pretty good on wifi, but it's really bad on 3G
Looking at your screenshot, you have a no bar signal, so it appears that may be what is draining your battery. Go to Settings, more...., Wireless & networks, and tick Use only 2G networks. Try that for a day and see what kind of improvement you get.

Check your wakelocks.... Kernel especially... And radio could be the cause too. Try the .54 radio.... Users reported stronger signals
Sent from my Nexus 4 using xda premium
If you use go sms, the update from the 8th (I believe) causes wakelocks.
Me too! I am getting worse. Brightness level is on minimum and only had it on like 100% for about 15 minutes. I don't get it, I have tried everything.

[Q] Probable battery issue???

Hello all,
I have a small query on my S4 which has just recently developed from what I can see. When my phone gets to about 20% or less, my phone just randomly switches off when I try to download an app or open an app. I am not sure if its the battery or a software issue but it is quite irritating. Has anyone experienced something similar and does anyone know if its a battery problem or not.
I dont want to buy another battery just in case it isnt that.
Cheers
VJ
Take a closer look at the Battery, if it slightly bloaded / expanded the Battery is defekt which cause exactly such problems.
If so replace the Battery under warranty!
It could be dangerous to load such a defekted Battery
It seems that some Battreys suffering by this problem even if they are only a couple of months old.
Regards
Cheers for that. I will have a look at it

Last week my battery wasn't lasting quite as long as expected.
Friday, my S4 started shutting down randomly (particularly when installing or opening apps) and attempts to reboot itself but fails at the Samsung logo. Non of these issues arise when connected to the charger.
I checked my battery which has bulged by maybe about 1mm in the middle each side.
I ordered a replacement stock battery yesterday and will let you know how I get on.
Just seen my battery and it definitely spins when put on a flat surface. There is also a bulge so I think I will need to look at a replacement battery going that will sort it out
Sent from my GT-I9505 using xda app-developers app
New battery arrived and installed.
All the issues have been resolved, therefore I conclude the original battery is defective as I suspected.
I will now pursue a replacement under warranty.
Good luck with yours.
Just got my new battery and trying it today. Comparing both batteries and it shows my old one was damaged. It looked 'pregnant' compared to the new one. Hopefully all sorted now. Thanks everyone for their help

[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.

Try calibrating the battery completely drain your phone then fully charge it

Have you solved using that method suggested? Anyway it's strange a battery lasts only a year -.-
