Recently I've noticed my phone dropping percentages within minutes, I've been on my phone for about 30 min just moderately surfing the web and it has dropped almost 30 percent. I tried juice defender, although it seemed it
worked somewhat it was really messing with my data connection. Anyone else experiencing this issue?

As of right now I'm just rooted with the update.zip, I did lag fix but unlag fixed shortly after. Didn't have this problem when I was stock battery actually listed a good amount time.
There are bugs with the displayed battery % not being accurate. Especially if you power down the phone while it's charging.
My Vibrant just eats battery by the minute... I am honestly not sure what is going on. IT's 2.30pm and I barely used the phone and it's down to 53% now from 9am.
What can I do to fix this? I have rooted and installed lag fix from this link
I had the same issue before applying ryanza one click lash fix. My battery now lasts aboutlag 2 days. Which lag fix did you apply ?

I know this doesn't help... but my phone is stock and with normal battery management practices I'm not having any real problems... However, I'm really used to my blackberry which could be left on forever without using any battery at all.

Yea compared to my last two smartphones, the vibrant battery life is no worse. It's definitely better than the n900. But no smart phone's battery life has compared to my blackberry's I used to use.

Fix permissions via recovery! Drain your battery till power down and recharge it fully while off if possible.
Vibe the XDApp
I had this issue. Turns out my battery had swollen due to over heating. Excessive use while on the charger. In the end, it would take 7 hours to charge 80%. Hence why it was on the charger.
Doesn't sound like you have the same issue. But of you start experiencing charging issue coupled with rapid draining get the barry replaced. No issues anymore.

Now I'm at work all day since using the phone for maybe 10m total and I'm at 42%. So basically 40m of use and 9 hrs of stand by I'm at 42%. I also g have everything off. Screen dimmed to 10 via night dimmer app. Could an ebay charger do this because mt car charger I got was from ebay.

i been having the same problem since i have rooted my device i dont know what else to do.... i am getting a new battery next week lets see how that works out. but i don't think its the battery
Hello everyone, i purchased my Nexus 7 and it arrived in the mail 3 days ago. And as with every other Android device ive ever owned, the batter is absolutely terrible. I get about 2hrs on screen time when browing the web and maybe playing an occasional game. Does anyone have any idea whats going on? Or have any way to help? Thanks so much
That is pretty bad. Try a factory reset. Might be something you installed.
I'd hate to do a factory reset cause I just barely got it set up but..I'll try it anyway tonight

Doing a factory reset before installing anything is becoming the gold standard.
Hope it helps you.
I get between 7-9 hours of active use. Sounds like some process is running amok on yours. I didn't factory reset when I bought it either....though I have rooted it since then, but battery life is about the same pre and post root.
You might want to consider a program to monitor battery use to see what's eating it up. Maybe do that before you factory reset it so you don't install the same thing again.

System panel is a good app to find what's using your CPU and better batterystats can help find what's keeping your phone from going to deep sleep. An easy way to see if this is the case is go into battery setting and select the first option(history details). Compare the Awake bar with the screen on bar. Those two should be nearly identical if not then you have a rogue app.

The one I've seen mentioned several times in here is BetterBatteryStats. I just don't want to drop $3.00 on something I don't need. It might help your issue though.

have you flashed any kernels or roms? sometimes this makes the tablet report the wrong battery stats for a bit.
did you run the battery down until it turns off and then give it a full charge? sometimes you have more juice than what is being reported. ive been stuck at 1-2% for over an hour before. Most likely its a rogue app though, system panel and better batterystats should find out what app it is. if they dont then it could be that you have a defective battery...
Been on mine continuously for 3 hrs 18 mins and at 60%. Excellent if you ask me. Next step up in battery life would be Transformer series with dock.

Quite the opposite for me; unlike every other Android device I've had (Nexus One, GS2) the battery life is excellent. I watched 720p mkv video on the train yesterday for a good 3 hours, and still had ~70% by the time I got home, from a full charge.
The battery life is excellent, as far as I'm concerned.

Don't think you needed to calibrate the battery to begin with. I usually get fine battery life without doing anything special.
Something must be causing the poor battery on your Nexus, Yesterday after my N7 was fully charged, I watched the movie Thor for 1hr and 54 minutes n and my battery only dropped to 83%.
I'm at 16 hours and 52 minutes with 3 hours and 44 minutes of on screen time, the battery is at 51%

My N7 is completely stock and has never been rooted. I also did do a couple charge cycles which didn't seem to help much. And better batterystats has AudioOut_2 at 38% (while I'm playing music) but other than that it doesn't seem to be a rogue app

Unless you listen to music for over 5 hours or streaming the songs it shouldnt use that much battery. If you can't find a wakelock with better battery stats then it might just be a bad unit.
Just recently my battery dies in under 8 hours while idle. Can be at 100 percent when I leave for work and 8 hours later when I get home it's dead. I can't figure out why it's dying so fast and I looked at the battery stats and dying see anything really out of the ordinary so I'm thinking by battery is about to die out. Any ideas or suggestions?
Also stock and not rooted on 4.2.2
Update: using better battery stats app it says 100% awake when screen is off but doesn't tell what's keeping it on.

Post all the summary screens here and let us be the judge of that
No time spent in either kernel or application wakelocks?
BTW, I get about 7.5 hours of screen-on time with stock 4.2.2. So, only 8 hours of time AWAKE but without the screen on does seem a little excessive. It would either have to be a rogue app that causes the rate governor to pump up the clock, or perhaps as you suggest a failing battery.

Your first and third image are nearly identical - but there sure doesn't seem to be anything significant showing up in the kernel wakelock screen.
Anything that uses more time in the Parital Wakelock screen? (not shown.)
Something to check if you suspect the battery is dying is the full charge and nearly discharged voltage range. I think Battery Widget will report that, or you can get it from
/sys/devices/platform/tegra-i2c.4/i2c-4/4-0055/power_supply/battery/voltage_now
Mine ranges from 3.58v to about 4.17v.
And I opened the voltage now file and got this 3791000

3.79v is about a 68% charge level on my battery - for whatever comparison that's worth. Yours was at 62% at "6:32", so maybe that's comparable. But 0% and 100% battery voltages would probably be more interesting for a "worn out" battery.
Thanks for the 2nd set of screen grabs... we're getting somewhere - I think.
WTF? The "6:35" image shows awake time of 9 minutes, 40 seconds... and the "6:34" image shows a partial wakelock of 51 min 4 sec for
NLP PendingIntentclient in com.google.android.googlequicksearchbox....
those can't possibly be from the same boot cycle. ???? Can they?
Anyway, assuming that the 6:34 image comes from the same boot cycle as the prior images at "5:43", then those 50-minute accumulated wakelocks for
NLP Pending.... and
LocationManagerService
seem extreme ... maybe ... if they happened when the screen was blanked ... dunno at this point.
I would run a test where you charge the battery and let it sit for 4-5 hours with the screen off the whole time, and then collect all those Better Battery Stats images in one go. If you see long wakelocks (tens and tens of minutes) while the device is supposed to be sleeping, those are the things I would investigate first.
I'm not sure where that NLP Pending... thing comes from, but since you are on pure stock... after you have collected the BatteryStats statistics and have a good hunch, you could try clearing cache and or data for the specific app you think might be involved.
(e.g. perhaps something like Settings -> Apps -> (All Tab) -> Google Search)
Because you have a pure stock tablet (and have just one recourse if things go South) don't go willy-nilly deleting app data and cache for system apps if you are not sure what the subsystem is. You don't want to get into a wedged boot having not backed up your SD card, because the only way to rectify that on a stock tablet will be to take a (stock) "factory reset" - which wipes EVERYTHING INCLUDING /sdcard.
good luck
Yeah they are from the same boot cycle and I've been on the battery for about 5 hours and haven't touched it except to reply here and I'm down to 35% since being off the charger from a full charge.

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??

Yup. Battery life on Moto X 4.4 is at least 50% better than 4.2.2 Moto X. My first full charge on ART was 34hs 2.5hrs SOT.
Here is my second full charge rundown:

3rd full charge is 8hrs 85% left (was watching youtube videos on LTE through lunch). 0 complaints. :good:

I'm having great battery life... Though, I am rooted and have some crap frozen, but the overall difference between stock 4.4 and rooted 4.4 is pretty minimal. Currently at 61% battery, 7.5hrs off charger, 2.5hr screen time. BT on 100% Wi-Fi on 50% GPS on 100%.
AT&T Moto X rocking rooted 4.4
I just did a full factory reset so I'm going to give it a couple of days to see if that helps.
For the people in this thread that say they are not having an issue.. what is typical for your Android OS service usage percent? My screen was my top drain before the update, but Android OS is now.
