Hey guys.
I have had a Nexus 7 since the end of July and I love it! However, recently I have been experiencing a weird problem with my battery. Normally, after a full charge I can get about 6 full days in just standby or about 5 if I use it for a considerable amount of time. What has happened recently is that my Nexus has dropped the battery percentage by a lot at completely random times. Like for instance, Friday night it was at about 15% when I left it. Now normally it'll only drain a few percentage points while in standby. I came home about 4 hours later to find it completely dead. That has never happened before. It gets weirder. Last night I went to bed with it at about 85% remaining. I woke up about 6 hours later and was surprised to see that it drained to 55% in just standby! Then after it drains a large amount, it goes back to normal standby behavior. (It is at 53% as I write this)
Any help would be greatly appreciated. Thanks!
Have you checked which apps are running in the background? Did you install any new apps around the time your issues began?

Sorry for the late reply. I have not installed anything new. I will see if it happens again. So far, it has not.
Thanks!

My Battery drained from 100% (it was fully charged, then I unplugged it and locked it) to 75% overnight.
What are some likely causes of this?
I noticed you have no signal. Constantly searching for a signal will drain the battery...
I've only had my N4 for a few days but the battery life has been good so far. A couple of brief observations...
1) On wifi only overnight (no SIM as I just got it and didn't have a micro yet) for 7+ hours. ZERO % drain...
2) On LTE (2-3 bars) for the past 3 hours. I left the phone and came back later. ZERO % drain...
Gmail is push, no GPS or BT. Only core apps running. I don't normally have anything in the back ground outside of lightflow...
Download GSam battery monitor
I noticed this also. I never had that much drain with my Galaxy Nexus.
I went out to lunch. Sent a few texts with google voice and looked up some random food articles on wiki for a few minutes. I was gone for 1-1.5 hours and now my battery is down to 47% from 75% this morning.
I'm going to download GSam and see what I get from there.
Edit: Installed GSam.
Attaching results from it.

Charge it fully tonight, unplug it in the morning, and then post your GSam results tomorrow night after a day of usage.
Mine has started loosing charge overnight too.
It won't turn of wifi when asleep either. Since I activated Google Now.
Mine lost 5%in 4hours overnight. Nothing running apart from mail and now notifications.

Your android OS usage is terribly high. That's my first suspect.

My android OS usage is very high as well... sometimes higher than the screen. I'm gonna try turning off google now to see if that does anything but other than that I have no idea what would be causing that...
The screenshots show app usage as being 50%+.. It is probably a rogue app you have running in the background.

As I said before, I believe it's some Google apps, I deleted a bunch of Google apps I don't use. My phone sleeps like a baby now. Overnight it only went down 2%.

I had the same issue for a couple of days. I would wake up to my phone only having 65% charge and the device would be rather warm. In my situation, I found that the charger was faulty. I noticed at times it would cause the phone to flicker back and forth from charging to in use. Lucky for me, I don't sleep well at night and I found the issue after my phone had been plugged in for 5 hours in the middle of the night. With that said, I also noticed the charger would make a high pitched hum/hiss. I swapped my charger out for my old Iphone 4 charger and I haven't had an issue.
Nearly a full day's results.
I left my phone charging from night until morning. I unplugged my phone sometime around 10-11am and I stepped out around 12:30.
It's 5:52 pm now.
I was out from around 12:30 to around 5ish. At around 5 my phone had 50-56% battery left. My friend's Iphone 5 had 75% left. Aside from my friend using his iphone as a GPS to navigate in the car (around 20 minutes) - we had roughly the same phone usage (by my estimate of course), we were at same locations and both of us are on the same network.
To be frank, I don't understand why my friend had more battery life than I did considering he was using gps. I do feel like there is something draining my phone battery.
My screen light settings are on automatic.
I've attached GSam and my list of applications.
From about 5 to now (5:52):
After a bit of surfing, installing 1 application to list my apps, emailing that app list to myself screenshotting the relevant data and emailing those screenshots to myself over wifi. I'm now down to 39%

9:12
3 hours and 20 mins down the line.
I'm at 10% battery.
I've been having strange battery drain issues, so I decided to use the factory images to restore the nexus 7 and I've booted up with 100%, connected to my WiFi network, no Google account entered, and let it sit and idle overnight.
After 8 hours I'm down to 56%. Which is roughly 5% per hour with zero apps installed. Is this normal or should I get it replaced?

Not normal for me, after my first full charge I got a full 3 days on battery with 5 1/2 hours of on screen time. Connected to WiFi and streaming sync on twitter.

compared to my tablet, it's not normal at all.
Damn... Figured as much. Time to return it to best buy.
Seems like a defected battery to me. Good luck with your new replacement
I`m having the same problem with 2 new (2013) 32 GB Nexus 7`s.
Terrible stand-by battery life. I started this thread: http://forum.xda-developers.com/showthread.php?t=2394813
Please let me know if the replacement tablet is any better
You definitely have an issue. Mine sat for 4 days, 5 hours and 34 minutes, WiFi on (Android OS - 26%, Tablet Idle - 24%, WiFi - 22%, Google Services - 16%) and only went from 100% - 54%.
Good and bad news.
Good: got it replaced and it's much better. Only dropped 2% over 9 hours idle.
Bad: this replacement has light bleed at the top. The other one had none.
I installed CM 10.2 last night. Left my tablet unplugged overnight. This morning: After 9hrs on battery, my battery went from 100% and stayed on 100%!! Wow! Now we're cooking. That's with Airplane mode off as well.
Good to see you here freeza!

I hated the lollipop OS so I went back to KitKat 4.4.4. Now just in the past week it's been nearly impossible to get this tablet to full charge. It takes HOURS just to charge even 20%. Now I've noticed in this past week that google play services is taking up a whopping 36% of my battery. And it has never done this before. Not only that but on the battery graph it shows that my tablet has been awake and has never went to sleep. Even after sitting, doing nothing for an hour and half while I was in my physics class. Even for hours overnight it stayed awake not once did it sleep. So I'm starting to wonder. Does anyone know what's going on here?

I bought a nexus 4 quite recently and the battery was actually quite fine. But recently, it started dying at random levels like around 30-40%. Today i charged it full to 100 and then rebooted to recovery which showed a 31% level. On restarting the system too showed 31%. I charged it again and repeated the process but it keeps returning to 31. Whats going on here? Attached is the battery graph showing severe loss of charge at every restart.

Brand new or used? The battery has a short lifespan, so if it has been used by someone for more than a year theres a big chance it's time to change it.
I've bought my N4 brand new in February 2014 and the battery is definitely much weaker. With light usage i get from 7am till bed time with less than 35%. I lose a lot of it on standby.
Well it was supposed to be new. It booted up with stock Jellybean. I've been using it for a couple of months only.
Hi guys
Just wondering if anyone else has noticed high battery drain on LMY48M?
Since the update my battery doesn't seem to be lasting the day if I have mobile data on and I use it occasionally. Basically unplug at 7:30am and by 3pm I need to start charging it. There's no obvious process draining it.
I did replace the battery 5 weeks ago and was working fine. Well into 20+ hours with use. Then not long after the update I noticed this issue.
Any thoughts on what could do?
Edit: Should have used the search (noob mistake I know) it's obviously an issue most are seeing on this build.
Are there any recommendations on Kernels to switch to, seraphore (sic) I've seen mentioned.
I'm always wary of updates in case something detrimental happens, but I recently updated to 48M and have seen no adverse effects. Phone on since 6:30 and still at 60%. Definitely no battery drain here.

Strangely enough it's behaving today. Had a SOD last night, cleared my cache and so far 12hrs since 100% and I've got 43% to go, reckons another 8 hours. This is with my usual usage.

Fingers crossed you've sorted it. 14 hours since 100% here and still have 45%. 12 hours to go. And to think I was considering replacing it with a 5X! [emoji50]
