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!
I've updated to 4.2 as soon as it came out, few apps didn't work but I soon noticed that it wasn't the issue.
The battery life on 4.2 seems to have drastically decreased for me. I was able to watch over 10 hours of video on maximum brightness with Wi-Fi and maximum volume, after update on MINIMUM brightness and half the volume I was able to pull off about 6 hours.
Did your battery life improve or gotten worse on 4.2?
Stand by time for me seems to have improved. No data to back that up, but I usually know where my battery is at anytime of day and it has been higher than usual since the update.

For me it seems to drain very fast, ever since the update AND I've got less apps since I did clean install. I kept same settings for Wi-Fi etc. Even Stand by seems to consume a lot more battery, I mean it drained 40% during the night. I wasn't downloading or anything.
Definitely worse. It even takes longer to charge.
The battery life after 4.2 update is awful.

I've just noticed that too. I was able to charge it overnight from scratch with extension cable fully. Now it goes just above 90%.

I really hope they fix it as I'm clearly not the only one.

Great!! I updated to 4.2 Tuesday and my last charge was Sunday afternoon. Still going strong with moderate use.

You guys should give it a few battery cycles before making a proper judgement

I updated to 4.2, and it drained my battery from 100% to 78% in 12 hours, with idle!!!
<<stock ROM, no-rooted, stock kernel, no installed apps>>
No difference for me. If anything it is better. Left my tablet idling after charge last night and it was still 100 percent when I woke up. On 4.1.2 it would generally go from 100 to 98 left overnight. Screen on time seems about the same.

You got big problem then. Wipe it might help
Definitely worse. Using it for ten minutes after a charge drains it by nearly ten percent, and this was after a full charge cycle. On conservative use it lasts me 6, maybe 7 hours, whereas on 4.1.2 with much more running at once I would ten hours easily. Its not that much, yeah, but I'm still going to downgrade. It's a good thing Google actually lets you downgrade unlike Apple.
for me battery life is much better. i get 17 hours with screen on 56% .
Mine has decrease a lot... now the back of my nexus 7 gets hot and drains the battery really fast.... anyone has a link to a better ROM or one that gives u a better battery life
?

man i follow my guide to update to 4.2 and i dont get any battery issues , if you wanna try http://forum.xda-developers.com/showthread.php?t=1990258
My battery is much improved. Before I was getting about 5 hours of screen on time with heavy use. After the update, I'm getting 7 hours of screen on time with heavy use.
Seems slightly better on stand by..that's for sure. Too soon to tell otherwise.

Hello,
After the update I noticed the tablet rebooting occasionally, so I flashed from scratch scrosler's 4.2 rom. The dev said is the official one, he just added root. I lost 25% in 7 hours of moderate use with auto brightness . Over the night battery remained at 100%.

After few battery cycles, I still have to keep my opinion of worse battery life sadly.
Just looking right now under battery settings, there seem to be many more "Google" things "Android OS (as it was before) Google Services, Android System, Tablet Idle, and Maps and Media server also seem to be taking up more battery.
A quick update on a weird bug I encountered in the N4 yesterday. I was outside and got home with my battery at around 50%. I plugged the phone in and look away for a couple of minutes and when I looked back at the phone and the battery was at 100%(!).
I knew this couldn't be right so I checked the battery graph and it showed a steep jump from 50 to 100 in a matter of minutes. I did a phone restart and the battery was back to the correct level and went back to charging normally. Unfortunately I forgot to screenshot the battery graph and after the reset the graph was reset as well.
Could this bug be one of the reasons why certain users are reporting very bad battery lives on the N4? I can imagine that if I had not been paying attention with the charging and just took the phone out to use later, the battery would have seemed to drop very quickly. How commonly could it happen even; has anyone else seen it?
This happened to me last night. I plugged it in to charge and it said the battery was at 100

This happened to me only once. I jumped from 1% to 100% in a minute I was like no way this thing charges that fast lol

Does seem like it is a common problem then. Better keep an eye out on the battery when charging it.

Add me to the list, a reboot after I observed the nano second charge to full capacity didn't even make it display properly. I didn't try a hard reboot however.
Not selling my GN just yet.
Hello, I've been using 4.3 since the day it first came out...I've never had any battery issues till recently...in fact I was quite impresses by the battery life on 4.3. I was getting 24h+ with 3-4h SOT and WiFi on the whole day. For the past 5 days I've been living in a different city...here I don't have WiFi so I use mobile data (EDGE). Not 3G. The problem is I now get sudden battery drains. I can't even get 10 hours out of this thing. Can anyone tell me where the problem is? Oh and the day I entered this city I charged my phone with a different charger...I'm pretty sure that shouldn't be an issue but I've mentioned that just in case. Thanks in advance

I have had my Galaxy S7 since about four days before it was officially released thanks to T-Mobile shipping it early. (I say this because I assume this is enough time for the battery to cycle)
I'm wondering if anyone else has experienced some crazy system battery drain? I have hardly used my phone today other than two phone calls that lasted about 2 minutes each. My Android System has used 42% battery and it's draining at about 5% an hour. I don't even have two hours of screen on time. I close my apps out when I am finished with them so I don't think that is the problem. I also have location turned off. Any ideas? :crying:
My doing the same. Not sure what's the big gap is about.

Mine was getting 7 hours sot for around 20 hrs of usage then all of a sudden the other day it started this crazy battery drain where it went from 100% to 80% in 2 hours with no use age. I didn't install anything new at all. So I did a factory reset and now it's back to the way it was.
I had to have had an app that went rogue as my device also was heating up. The reset was just the quickest and easier way to correct. Besides with no root it's almost impossible to find the culprit

I had a battery drain issue and I traced it to the "My Places" app that the contexual location edge bar uses to determine your location. It was keeping my GPS on and keeping my phone awake. Turned it off and back to 5+ hours screen on time.
