Poor battery life? - Nexus 7 General

I have an iPad 3 and a rooted Nook with CyanogenMod on it. Both go days and days on standby, meaning fully on but the screen just off. My N7 which I just got a week ago is totally dead after 24 hours, even if I have not used it at all.
Is this normal?

Mine lasts about two days with minimal use.
Make sure wifi is set to sleep while screen off.

You need to get something like Gsam from playstore. It may tell you if an app is draining your battery severely, or if apps are waking the tab too much.
Also, Cpuspy will tell you if its going into deep sleep. On playstore as well.
Those will hopefully tell you why your battery is draining. I charge my N7 about every other day....maybe 3. Its mostly used to read books, and sometimes some games. So definitely not heavy use. But standby, about 1 percent lost overnight.

Not normal. Just did over 3 days with 6 hrs screen on time. Turn wifi off when screen is off and make sue you dont have any apps running non stop. Better battery thats is a north app for this. Check the partial wakelocks

Hmm ok, I will try to figure out what's going on. I am using MightyText... could that be it?

That not normal at all try suggestions above, mine drop only about 0.2% per hour on standby with wifi-on and screen-off.

Hi
How long does it take to charge the device from 2% to 100. %
Mine is more than six hours, is it normal?

Mine takes 2 to 3 usually. Are you using the cable and charger that came with it? If not, that can play a roll. Also, if something greedy is running, can slow charge times too.

Mine drains pretty quick when in use, but if idling, it lasts a very long time. I've seen it not drop 1% until maybe 2-3 hours idling. Heavy usage drains like 1% every 10-15 min.

Same here. Idling last night at 70%. Woke up 7 hours later at 69%(airplane mode) but as soon as I start using, drops super fast.

I think it is MightyText. It seems if I get a text from someone I have not received a text from before it opens a window on the locked screen showing the text and then the screen never goes back to sleep. It stays on until the battery runs out. If I get a text from someone I had a conversation already going with this does not happen.
Pretty weird but it explains why it is totally dead when I would get home from work.

I had poor battery life too,but I've done something that someway fixed that.
I format system etc and reinstall 4.2.2 stock with stock kernel.
After some charging circles here the results

i know if you leave skype on it drains an insane amount of battery...so i keep it logged out now whenever I don't use it

I would have liked to see the main battery status page. See if you did anything with it, or just kept the screen alive for 9 hours? LOL.

I've seen couple of movies about 6 hours using mx player, and about 3 hours WiFi internet browsing using Firefox and tapatalk.

[Q] Bad Battery Life?

Is the O4X's battery life as bad as gsmarena is saying? Just a little over 4 hours of video playback and 4 hours of web browsing?
If you read the comments of the blog article on it, you will see that there is a lot of discussion over the brightness.
By comparison to the SGS3 and One X, the Optiums has a much brighter screen which will mean a lower battery life. Of course if they set all the phones to the same actual brightness (not percentage) the numbers would be different.
I am currently waiting delivery of my 4X, but after I have conditioned the battery (let the handset configure itself to the battery), I'll definitely be seeing what its capable of.
Alright thanks, I hope you'll be able to get back to this thread when you find out more.
I've had mine since friday and I think I've charged it about 3 or 4 times now and the battery life is getting better. It lasted only about 2 hours when I first charged it and started it for the first time. But I was using it constantly.
Today I started it in the morning (fully charged) before going to work and now, 10 pm, it's been on for about 16 hours and I have 40% left. Data have been on all day and I've been signed in to Google Talk all day, I've browsed the web for a total of aprox. 1 hour, used the camera, tested the GPS and been chatting with a friend on talk. So I'm pretty satisfied so far.
It's better than my O2X.

That's good to hear. How many hours was the screen on?
I'm not sure unfortunately. But i would say between 2-4 hours.
Edit: okay it was a little less than I thought. The. Battery usage in settings says the screen have been on for two and a half hours. And that's including the time I have used after 40%. I'm down to 25% now.
My Battery lasts after a few cycles all over two Days with medium Usage (No gaming - WA, FB, eMail)........
i ca go for 1 day, with a bit gaming and usual use.
I have slightly longer battery life on my 4X HD than on my Nexus S when using the phones in the same way (casual use). But I think there is room for improvment on the battery life with more optimized software either from LG or when we start seeing custom roms for this device.
I charged mine to 100% and just dropped 8% in 25 minutes, 20 minutes of that was driving and not using the phone, no Bluetooth or anything like that. The battery life is shocking and can't wait for extended ones to become available. Besides that I truly love this phone

How many complete charge cycles have you done?
Sent from my LG-P880 using xda app-developers app
When I got my p880 I did 3 battery cycles, and I could only get about 8 hours of standby alone, no other use at all. I then did a factory reset and formatting of the memory card, which I hadn't done when I switched from my old SE X8. Now my p880 can easily go more than a day with some gaming, calls, browsing etc. My guess is that old android files on the memory card was the reason for the bad battery life. No expert though, maybe someone else has a better idea.
Today I tried the Chrome browser, and it really drained the battery. Something like 20% after browsing for 15 mins. Anybody else have experience with this?
Overall I'm really happy with this phone, great screen, fluid operation, good battery.
I've had battery drainage issues with the chrome browser as well. Even in stand-by the browser would drain the battery. It has only happened like two times for me in the four weeks i've had the phone, so not a biggy but still something you should be aware of, if you experience battery drainage issues

Battery Life

Had my N7 on the charger all day while at work. Got home, unplugged it and fired up Splashtop to stream MLG Summer Arena (flash content) with my desktop. Screen at full brightness, headphones plugged in, and maxed volume. About 2.5 hours streaming and a half our of Dead Trigger, I'm down to 27% battery life.
Feels like the battery performance isnt anywhere near the 8 or 9 hours claimed by Google and Asus. Am I missing something here? Anyone else feel like battery drain is really high? Stock, un-rooted, updated to 4.1.1.
Have a trip in two weeks with a 4.5 hour plane ride and would be nice know my tablet could keep me entertained for the trip...

Even though I don't have mine yet I can say full brightness on screen can effect your battery life. I would suggest looking at what apps are running and possibly what could be eating your battery life.
Full brightness, thats the root cause. Try to reduce to, let say 50% ... Or as lowest as you feel OK.
When I use my gnex at home, I set to 15% ... Thats enough and still very bright.
Outside I use auto ...
Thats why I have a toggle widget for that ...
And I can have my gnex easily run for more than 48 hours stand by woth almost 4 hours screen on time

I dunno, that's weird. I've been playing with this thing all day and have 3 hours screen time and 65% left.. live wallpaper, Dead Trigger an hour, SuperGNES (FF3) two hours, XDA and web browsing. I'm on 50% percent brightness though.
Sent from my Nexus 7 using xda app-developers app
100% brightest is way too bright indoors for me. Optimal indoors for me is about 30% and probably wouldn't go above 50%.
I've been getting 6 and a half hrs screen on time with over a day on battery, this has been 3 separate times. I use this tablet a lot, total time with me adding up that screen on time is over 25hrs maybe 30. I'm not counting the time when I first got it and ran it down several times before I was getting way better screen on time.

I use auto brightness and I'm getting way more than 10 hours use. Thats browsing and the occasional youtube.
Very impressed with the battery life and the whole Nexus experience.
My brightness is to 12%. More than bright enough for me. Getting around 9-10 hours with moderate to heavy usage. Very impressed with battery life.
I get better battery on CyanogenMod then I did on stock. Plus I can underclock to as low as 800mhz and it still runs like a champ.
Sent from my Nexus 7 using xda premium
I have been amazed at how long it last.Over 10 hours with headphones running listening to lots of songs, trying out different apps and then watched the movie.Still never got under the 30% mark on the battery.
I've knocked down the brightness to 50% and will see how well the battery lasts after charging last night. So far I've been off the charger for a little over an hour with 40 minutes of screen time, down to 91‰ battery life.
The stock ROM doesn't have a way to take screen shots, does it?
Seriously, you had brightness and volume at 100% while using Splashtop, then gaming (pretty high intensity stuff) and you're surprised it lasted less than a stated time for Web browsing at like 50% or less brightness?

I want to say the battery tests were performed at similar conditions while watching a movie for the eight to nine hour rating. Perhaps Splashtop pulling so much bandwidth on the network was a factor.
2.5 hours since unplug, 2 hours of screen time, down to 65% battery. YouTube, Chrome, Dead Trigger, and Facebook so far this morning.

Disable Wifi while you're in the air. That should make a difference.
my battery life has been spectacular. one other thing I noticed. when it charges to 100% (my nexus S never did), it stays there until you start using it. Best battery life of any mobile device I have had, ever. Except for my NOkia candy bar phones that stay charged for days.
I think my nexus may be defective. At first I left it at auto brightness, and drained the battery with 4 hours of screen time only web surfing. I've manually set the brightness to 35, and I still only get about 4.5 hours. This is just using Google chrome, no music. Throw in the occasional 10 minutes of world of too. Also what is standby drain for you guys? I lose 14% overnight, about 7 hours.

What screen brightness are you using? Do you close all apps that you aren't currently using? My screen is the biggest battery drain, but I keep the brightness to sub 40. Normally I would just use auto, but I had no luck with it.

4326mAh battery, 2A charger, 2.1 hours theoretically. Realistically, 2.5-3.0 if pretty much empty.
If you're using a non standard cable or charger, who knows what the charger is actually outputting. If you're charging from your computer USB Port, that's 500mAh, so 8.6+ hours. Some random phone charger, probably 1000mAh, 4.3+ hours, etc.
The brightness of the display adds to some of the drain I notice, when possible I keep mine somewhat on the dimside, obviously if I'm in an area of bright light and it hard to see then I'll crank up the brightness.
Can't complain about battery usage.. It's amazingly energy efficient even on a stock kernel considering the horsepower this thing has.. I average 20hrs or so with moderate to heavy usage.

I've had really bad drains since 4.1.2. I think I've narrowed it down to an issue with Google Play. I've noticed it several times - Very good battery life, but then it will go down fast, even when sitting unused. If I check battery usage, Google Play is always number one with >50% of the use.
If I force close GP, all will be well for about a day, but eventually it happens again.
I also felt it, but only by that much...not too obvious. From full charge, after only night idle, drop 3 percent compare to last time 1 or 2 percent

So is the general consensus on battery life that it's good enough to get through a day with moderate type usage? One of the pros of active notifications is that it decreases your battery usage because you're not constantly waking up the phone to check notifications and time, right? I was kinda meh on the whole customization thing til I just went through Moto Maker and I kinda fell in love with what I designed. I know I like the size and on-screen buttons a whole lot more than the Maxx. It's just a question of whether I can sacrifice the larger battery and I know I don't need the two full days, but I don't wanna be stuck on a charger before one day is out either.
Any review online is saying it's above average battery life.
After a full charge, screen time over 3 hours with 55% battery left. I'm impressed.

I got a pretty much linear drop in battery regardless of usage yesterday. I put it on the charger after about 18 hours, but it would've made it to at least 24 had I left it off the charger. The interesting thing is that I had it hooked up to my car stereo to listen to music for a 2.5 hour drive, mostly with the screen off, and there wasn't any noticable difference in battery life. Also, I could hear stuff in the music i've never heard before, i.e. the sound is amazing.

After almost a week of using it, I actually find the battery life is a bit annoying in a good way though. I am not a heavy user. During the day, a dozen of times of youtube+netflix during breaks, a few phone calls and sms, while outside always have gps on. At the end of the day, I have about half battery left. To charge it over the night is somewhat electricity waste. But not charging it is to leave my next day somewhat anxious. So yeah, maybe I am too greedy in hoping for two days no charging. My Nexus 4 really requires at least one charge a day and this habit has grown on me. Oh well...let's hope after JB 4.3 update, X's battery life can be prolonged a little more
For the people that have posted stats. Is your battery saver on or off?
My best battery cycle was 31 hours standby and close to four hours screen time. It died before I could take screenshots though, will try again on this battery cycle.

Something I was looking forward to. This suggests the Nexus does have great idle time. And the drain is mostly because of the screen. People are expecting magic with such a screen I guess.

not sure if this will make a difference for you but 3 things that i did is getting me 4+ hours a day screen on time easily. turn off location services completly (just turn them on demand if prompted), disabling google now launchers always listening option, and my personal best fix, disabling tilt scrolling in the chrome browser. tilt scrolling is a little janky atm because it never actually shuts off, so chrome is always registering any device movement in your pocket or whatever even if the chrome app isnt even open, and disabling that helped a TON
