I'm not sure what's going on with the graph from my battery usage page. For some reasons, it would jump to 100% which is impossible. Anyone of you has seen something like this before?
Thanks in advance!

Same here... Every discharge cycle. But performance and battery life are not compromised....
I noticed the same thing today for the first time. But not as bad or as much as yours is showing.
I see those spikes on my Nexus 7 2013. And I get a terrible battery as well. My tablet loses about %30 of its battery charge during night when it is in sleep mode. Does anybody experience the same issue? Is there a way to fix this?

You must have an app installed that's causing that much drop off. Mine drops off like 2%.

I have seen spike on mine, too, but not up to 100%, only 1-2% more than its actual level. I thought it's because it was the first charge cycle and the reading weren't yet calibrated. I'll see if they go away after a few more cycles.
I don't have battery drain, as well, I lose 2-3% overnight with wifi and sync still on.

You can try an app called BetterBatteryStats it gives you a more detailed look at what's using your battery.

Hey everyone,
My Nexus 7 (2013) is having the same problem with battery graph. There are about 2-3 spikes to 100% in every discharge cycle.
I noticed this problem has been reported in different cycles, but no one seems to be able to give a definite answer of what the source of this problem is.
BTW, after a reset to factory settings, the problem still persists.
ANY idea why this is happening???

I recently bought a GSM galaxy nexus (NTT DoCoMo version) and I use it on T-Mobile's prepaid network. The original battery that it came with was terrible.. Literally only lasted 7 hours regardless of screen on time. So I bought a stock Samsung battery off eBay thinking maybe it was a bad battery. No help whatsoever. I've flashed different ROMs, radios, and different kernels. Can anyone help me figure out what's going on? I had a Sprint Galaxy Nexus and I could get up to a day on the battery with 2.5 hours of screen on time so I know the Galaxy Nexus can last a long time. What's the deal?

Could you post some info on battery drain statistics from battery settings tab or preferably gsam monitor over a full drain? I could probably help you out, just need some more info. Also try flashing fancy kernel if you haven't already. This is a newer kernel that gives the best battery life you'll find freshly flashed.
Before discharging toget battery stats I would try charging to 100% and using "battery calibration" by NeMa to clean your phone's batterystats file and then drain to zero with a screen flashlight or running gallery slideshow. This can always be a problem no matter how healthy your battery is.

This is what I have showing for my battery so far. I flashed the newest radio last night and that seems to have helped a little bit with the battery. I have tried the battery calibration and it didn't really seem to help much.

I have flashed a stock 4.2.2 ROM a week or so ago and I was still having this issue. I bought a new battery too and its still happening. Flashed the fancy kernel today and it seems to be helping a lot actually.
Sent from my Galaxy Nexus using xda app-developers app
The stock kernel performs way better then what you are experiencing. A custom kernel may help a bit, but it's not magic. I'd recommend using the app BetterBatteryStats in order to find out what's going on.
Do any of you think that me restoring apps would have anything to do with the battery drain? I'm not seeing anything out of the ordinary in the GSAM battery stats but the battery drains way too quickly. 10% per hour even when I'm not using it..

Glad to hear that fancy kernel is helping. It's probably the closest thing to magic you'll find. I agree that 1 hour of screen time and under 12 hours is under par, but I was having these same issues 2 months ago and could not believe how crappy battery life was. It really got better though trying a bunch of different radios to find the right ones, using minimal gapps/resource hogging apps as possible, finding the right build.prop tweaks to use, and most helpful flashing some good reliable kernels like fancy and AK/anarkia that have incredibly useful customizations that stock just doesn't have, I.e., contrast and color settings, battery friendly governors and frequency profiles, optimized smart-reflex, and custom regulator voltages for display.
Well, didn't feel like it lasted too long. Fell asleep with my battery at 33%, woke up 3 hours later and it's dead. I'm ready to throw this phone out the window.

I've tried to find a rom and kerneI that would help with battery too, nothing made that much of a difference though. I use the 2x battery saver app now. I get at least double the battery life sometimes more.

I see you got the app. Good. Now a few minutes isn't enough time to gather reliable stats. Review the results after a full drain cycle of the battery. Check partial wakelocks and alarms for suspicious activity.

Here's what was listed on BBS after a full drain. Do you see anything unusual? I turned my data on and kept it on 2G to prevent the no or unknown signal from eating more battery but that was the only change. Battery life still looks terrible.

No need for the snake oil app, as simply unplugging the phone after a full charge wipes battery stats. Wiping battery stats and draining to zero aren't going to have any bearing whatsoever on this issue and would needlessly shorten the battery's serviceable lifespan.

Whoops.. I forgot to screenshot those. I'll get those later today. So I put my phone in airplane mode to see if maybe it was the reception... Phone kept draining. I will try to wipe everything off the phone later and not install any apps and see if that helps.

According to these stats, it looks like Google talk and the calendar are my biggest wake locks? I disabled Google talk, turned off location history for Google maps last night, what should I do about the calendar? I feel like my phone is becoming useless because I have disabled so many things.

So late last week I installed liquid smooth and it was working awesome! was seeing -2.3% an hour on my battery drain. but as of two days ago, i'm getting a low of -13% drain an hour and sometimes all the way up to -38% an hour! The charge rate has even fallen from 24% an hour down to a cahrge rate of 10% an hour.
I think the culprit is the screen because it shows at >50% on the battery monitor and in the app "battery drain"
I've honestly searched and searched but can't find a solution to this. How can I pinpoint why my screen is using so much battery (brightness is on auto) even when my phone is in standby most of the day?
Same problem mate, mine is almost 80% drain by screen only..I replaced new battery also in RMA but its also not worked, maybe new update of android fix the problem..mine currently is 4.2.2 JB on nexus 7

Got my new N7 today. After I charged the battery to 100%, it remains at 100%. I have it on for 3 hours now and it still says 100%. Anyone else experiencing this? Thanks.
So they weren't kidding about good battery life
Try restarting?

thanks for pointing that out. I really didn't know it.
the thing is, prolly the device is doing some good deep sleep, with no radio to disturb the battery.
cell radio often takes about 25-30 % of battery. with no radio, no battety drain.
My tablet has been at 25-30 for about 8 hours now with light use. Network activity is minimal during this time.

No worries ...the battery life is jus amazing on this device is all....I was shocked after first cycle...compared to my other nexus devices and even my 10' this is great...:thumbup:

Since installing 4.4.2 my battery isn't discharging, at all! It's been stuck on 100% for the past four days. I haven't really used it much since but the battery should be way down by now.
Isn't that a good thing?

Are you still having the same issue?
Because I think I'm maybe having the same problem.
My tablet keep shutting off at 40% as if is 0%. It all started since this past weekend.
My tablet is unrooted ,try to search the web for a solution but haven't found one yet.
I'm trying avoiding to do a factory rest because I read the issue still persist.
Everytime I recharge my tablet it stay a long time on 100% and the moment it reach 40% it shut down a,msg appear saying battery low and shut off.
Also take note I've read about those app calibrator but keep reading that a myth.
Let me know if your still having the same problem?
No, I actually fixed the issue. Believe it or not I used a calibrating app and Root Cleaner and did a full clean and it appears to be working as normal now. I'll add later which battery app I used, can't remember the name.
EDIT : Actually it was just Root Cleaner. It has a batter calibration setting.

Either a CPU max run state...or a serious wake lock...or both..
Zero lemon getting drained like that is a serious problem...
I would suggest a "complete" wipe...and the flashing of a rooted stock rom as a test base...
If the device still exhibits the behavior...then a hardware issue may be at Work here...
If the device gets hot to the touch....then get the device to a stock and clean state...so some unmodified testing can take place...
Let us know...g

Even if you leave your screen on, never turn off zerolemon should still last you much longer than 4 hours of screen time. I have one, I get 3 days usage out of it
