I didn't take a screenshot, but last night I plugged it in because the battery was down to 10%. My time on the battery was somewhere around 5 days and 5 hours, but I don't use it a ton. There was still a decent amount of web browsing and a bit of game playing though.

Battery Discharging When OFF!

Fully charged up my new Nexus 7 turned unit off left it alone for about 24 hours tunred it back on to bring with me to the Plaza, only 25% charge left. It does seem to pretty well when in use, however. Whats your idle time charge like. I can leave my iPad 1 turned on and idle for days with no appreciable battery drain...Oh I also have the Screen Flicker issue, so I my have to return for exchange. A little dissapointing - LOVE the tablet however.
[Nexus 7 General] jphilippon:
That's very very bad. My idle could probably go for 4-5 days easy. I don't charge it for 3-4 days and it never gets below 30 ish, and that's with normal usage of an hour or two a night.

[Nexus 7 General] Skyfall007:

[Nexus 7 General] TheAtheistReverend:
There are a lot of other stats available that you didn't include. They're found on the screen that first comes up when you click battery, and when you click the graph from there. Without those stats, we can't make any assumptions about your N7. Take a look at the screen time on the post I had just put up. My screen time isn't very different from yours, but my N7 has been up for over 3 days. If you had come down from a full charge in less than a day and with only 3 hours of screen time we could look for something wrong.

You have to provide more information, or you can't be helped.

With your stock running Franco, does the nexus feel smoother and faster too?
[Nexus 7 General] qualitymove13:
To be honest, I have never had a problem running stock and getting 7+ hours of screen time over 2-3 days. Franco's kernel (now on R41) just allows me top "play" with settings a little more using the Trickster Mod app. I game about two hours per cycle, browse, music, and gtalk for the rest so I dont need much "oomph" if you will.

Head to his thread and give it a shot. They are very helpful with settings tweaks.

[Nexus 7 General] RnRexpress3423:
Fairly simple. Turn off most options when not in use such as WiFi, auto sync and change your refresh intervals to about four hours so your apps aren't constantly sucking up battery while your screen is off and on WiFi. Dim your brightness as well when in dark places as the lowest setting works pretty well. Few tips that should help a majority of people.

[Nexus 7 General] Josh98:
Hey guys,

Finding the thread very useful for gauging my battery - felt like it's dropped a lot recently so just trying to test it, reverted fully to stock.

Wondering if anyone could post their charging times as well? Feel like that seems to be taking longer but that might just be me.
[Nexus 7 General] xShifty:
Mine from yesterday, charged it at about 10%, running SmoothROM 5.0 with LeanKernel 1.5.4 and have it clocked down to 102-760 most of the time and use it on 0% brightness.

Judging from the other screenshots here, I guess the governor is doing plenty to keep the battery usage down even if I don't lower the max clock.
[Nexus 7 General] Josh98:
According to Asus's site you should be able to get 9.5hrs of WiFi version with the following:

- Playing a 720p video (with external headphones)

- Brightness at 100 nits (looked it up, N7 is 400 at full, so that's at 25%)

- WiFi on.

- Gmail logged in.

That's a little vague as it would depend on the video, player and whether WiFi is connected and gmail etc is syncing but either way I'm fairly certain I wouldn't get close to that. I assume that means no screen touching during the video also.v

Going to try test this as best I can see what I get.
[Nexus 7 General] FitAmp:
That also means with no rogue apps draining your battery.

Sure, well I've just completely reverted to stock from PA so shouldn't have any rogue apps installed and running to cause issues.

[Nexus 7 General] Josh98:
Yeah. At 41% now, same usage and brightness. 3hrs 20 mins screen time. It's better than if has been. That'll be around 6 hours screen time at 25% brightness, basic/moderate use over WiFi.
[Nexus 7 General] Satinfloss:
Running PA nightly and mkernel @ recommended settings. I do a good amount of browsing and moderate gaming.
[Nexus 7 General] FitAmp:
Seems pretty good. Remember it takes a full cycle or two after clean flashing a rom for battery readings to stabilize. Also I recommend flashing a custom kernel. Not only for battery but for added performance and features.

Stock 4.2.2+custom kernel is a great mix. I've had best battery with this combination. About 10hr onscreen time.

Press thanks if I helped ~ Nexus7/ParanoidAndroid/M-Kernel/NovaPrime
[Nexus 7 General] Josh98:
Thanks for the help, yeah well I've usually run Franco or M Kernel with PA but was finding performance and battery worse for some reason which is why I came fully to stock to see if it was hardware.

Damn, wish I was getting that with that combination! Where are the recommended settings? Also what I'd your brightness and other settings? (background processes etc?)
[Nexus 7 General] najaboy:
A couple clarifications....

Battery indication is no less stable immediately after a rom flash than it was prior. Charge indication is handled by the battery itself. What you're waiting for after a flash is for the kernel to stabilize and initial battery-draining services such as syncing to Google's servers to do their thing

Full charge/discharge cycles will contribute nothing towards stabilization and have an overall negative effect on the battery. At most, a full cycle should be performed once every 3-4 months to ”calibrate” the battery's internal fuel gauge. Full cycles will shorten the battery's usable life.

On the first post Metallice has the recommended settings and I leave my brightness on auto. I do have Google Sync and location access off because I don't really care for the Google Now telling me how long it's going to take for me to get to school/work back. I haven't tried experimenting with undervolting yet but plan on once midterms are done for me. I do have an app called "Greenify" which allows me to set chosen applications (i.e Facebook, twitter, scorecenter etc) to hibernate until I activate them myself. I'm not actually sure if it has helped a whole lot but many people have claimed they have experienced better battery life on the xda post.

[Nexus 7 General] bftb0:
I took a little bit more graphical/analytical approach - see attached image.

Stock 4.2.2 (JDQ39) ROM. Web browsing (load pages & read them.) Screen brightness set to minimum. More reading than browsing, so power usage dominated by the screen (70-80%) No effort made to kill tasks, turn off WiFi or GPS, or anything else.

Despite Asus' claim of "9.5 hours", it is rare that I get more than 7.5-8.5 hrs of screen-on time - about 14%/hour drain with just the screen on seems average. Overnight (say 12 hrs) about -4% battery drain. (Same deal there - no effort to shut anything off, kill apps, etc).
