I watched an episode of Sons Of Anarchy on mxplayer, a Mumford and sons concert on YouTube along with some other YouTube videos Web browsing and messing around on xda, tapatalk must have been misbehaving while I was at work, because it drained 9% battery while I was working, normal standby in that time is about 3% for me. I'm pretty happy with my battery life, I've never gone more than 7ish hours real world but if I watched all video I could see 10 hours I bet. I'm stock and not rooted, auto brightness haven't really done anything to save battery.
[Nexus 7 General] worx54:
I don't understand... If they advertise the tablet for 9 hours of battery runtime for watching videos, doesn't that mean it should have 9 hours of screen time on?
[Nexus 7 General] bharris25:
Depending on what you're doing, obviously not going to be able to play dead trigger for 9 hours on max brightness, taxes the processor too much, playing video isn't as taxing. Screen brightness is by far the biggest hog, watching a movie in a dark room with auto brightness gets good battery for me. I've never gotten 9 hours but I've never tried. I don't want to have to struggle to see the screen.
[Nexus 7 General] najaboy:
Theoretically, yes. In the real world, however, there are too many variables that come into play.
[Nexus 7 General] K3lthuzad:
I get maybe 5-6 hours if it's browsing/PDFs, but it's usually closer to 4 if I play maybe an hour of games in a day and YouTube a bunch.

[Nexus 7 General] Copitox:
Wow. I don't get nearly this great battery times on my two days old N7 running stock 4.2. I mean, battery life is good: while sleeping, seems like it could last forever! But when actually using it, battery seems to drain at a faster rate than what I can see on your screenshots. I've been hearing 4.1.2 works much better than 4.2. Should I downgrade? If so, how?

I'm sorry i'm such a noob.
[Nexus 7 General] C4SCA:
to downgrade use fastboot.... u need to have your bootloader unlocked and the correct drivers installed in your pc. then donwload the factory images from google website (google for: nexus images) and flash them via fastboot (command prompt on pc)
[Nexus 7 General] Nospin:
Insane life on 4.2. Don't know what changed, initially it was horrible but after the tablet sat 2 days turned off it has turned into a battery life machine.
[Nexus 7 General] O2Blevel:
Shouldn't your 'Awake' and 'Screen On' be about the same in your bottom image. Mine is the same way with 4.2 but it wasn't like that in 4.1.2.
[Nexus 7 General] Copitox:
Ok, i justo rolled back to 4.1.2 and I have much better battery life. I now have like about two hours every 10% of battery on medium to high use. Much more than on 4.2. I,m sitcking with it by now.

The pop-up is pretty annoying though.
[Nexus 7 General] Copitox:
Is this battery life above, below, or just average?

[Nexus 7 General] tye_time:
Yep, totally stock... Don't have Google now on as it isn't that big a deal for me. I also have GPS and NFC turned off as I don't use them. Not sure how much battery that all saves though. Brightness is kept at 50%.

If you haven't factory reset then do that and your battery will bounce back, mine did.

What is "Media Server"?

I notice if you stay in the battery screen and hit refresh and keep going back into the "Media Server" part, the seconds keep ticking up... but it's not constantly going up doing other stuff...

I have 2 days standby, around 4.5 hours screen time, 50% battery... but "Media Server" has 1.5 hours wake time?:rolleyes:

Managed about 1day 5hrs on battery.
[Nexus 7 General] Chronix3010:
Will i keep all my apps if I do that?

My usage, is that any good?
[Nexus 7 General] bharris25:
Your apps will auto install when you first boot back up after factory reset but you'll lose data if you don't back it up, pics and such. Your usage looks pretty decent though, I get 6 and a half hours of screen on time easy, if I'm mostly watching video I can get probably 8 hours though. I only factory reset because I had more than normal battery drain on standby.
[Nexus 7 General] turdbogls:
No...you loose all your apps and internal memory when you factory reset through the settings ( factory reset through a custom recovery doesn't touch your internal memory)

But I wouldnt worry about it with your numbers.... Those are fantastic from what I have seen. I had a clean install of 4.2 and get roughly 5hrs of screen on time.

This happened with me yesterday. I did two things : First, went to Google Now and 'enabled' location settings there. After that, I rebooted. It seemed to have solved the problem for now. Overnight, the tablet did not lose due to Google Services. Will check again today.
[Nexus 7 General] jb0ne:
I haven't been plugged in since last night - 4.2.1 stock, rooted. Used all day at work for calendar, task manager, email, some gps, etc, come home and I still have 61%. Unreal how long this battery lasts on stock.

I do wonder why NFC services is taking up the 2nd most power consumer though...
[Nexus 7 General] ruizinhoandre:
Its normal that the n7 is having a battery drain of 8% after i left him 24h Turned off?

I didn't use the tablet much except surf the web and read articles on Pulse during school.

I've got mine Nexus 7 (16GB, stock 4.2.1, no root) for more than a week or so and I'm not very satisfied with the battery life so I tried to test it with some heavy gaming, I disconnected fully charged device from AC and run the game (Hamilton's Adventure THD to be specific), display brightness manually set around 60-65%, wifi turned off and the result is 3:15 hours. Charging than took almost 4 hours (with the display off), to be specific 1% - 99% in less than 3 hours and the last 1% (99% - 100%) almost an hour, is it normal? I'm running Battery HD Pro widget by smallte.ch and it says (by the global statistics from Nexus 7 users) the fully charged device should handle 2:49 hours of 3D gaming and 4:31 hours of 2D gaming (which seems kinda short by my taste) but it also says it should handle 14:30 hours of video playback (which is I believe impossible)

so my question is, should I return my device and ask for the new one because of the battery life or is it overall normal? (battery drain by heavy gaming and strange charging).. I've been through this whole thread and compared to the screenshots here I'd expect better battery life from my device, right?
[Nexus 7 General] C4SCA:
Charging time is normal but and battery life is based on every day usage wich means screen brightness between 20 and 50 and light to heavy usage not only heavy usage such as gaming. I think 3hh30 of gaming at that brightness good..

On my S3/Note 2, every time I use my phone, both Screen On and Awake will be reflected.

On Nexus 7 however, when I'm using the tablet, even though Screen On is reflected, Awake isn't. Is this a bug or a new thing on Jellybean 4.2 or simply a nexus/stock android thing? If it's a stock android thing, then what does Awake actually mean?
