Battery life is horrible! - Nexus 7 (2013) General

I purposely left my phone off charge over night to see how much battery drains. In 8 hours it drained 20% with is wrong??

Sounds like your device isn't sleeping. My standby battery life is excellent, less than 1% an hour. On my old N7 I had to turn WiFi off to get good standby, on this one I usually just leave it on as it still doesn't lose anything to speak of.

So yesterday I spent the day rooting and installing CyanogenMod and still I'm losing 2.5% battery an hour in standby/sleep mode! What's the deal?

Deal is stock will always give you the best battery life. Also, ROMS usually take few days to settle after flashing.

ICS battery use

I have been using my phone for about two hours straight now and it seems that android OS is using more battery than the screen. I thought the screen was the biggest battery drain.
Before you ask, this is the stats right from a fresh charge.

Nexus 7 battery drain

Hi. It has been two weeks since I got the nexus 7. At first, the battery lasted for a long time. Now I'm realizing that it is draining much quicker than it is supposed to. What should I do?

Turn off all the gimmicky smart features and disabled as many of the bloatware apps that you can.

Battery life for me has been stellar. Yesterday was the first full day of use for me and I was at 15 hours with 56% percent of battery left with 3 hours of on screen time. I haven't changed a thing as far as controls. Today I've turned off a few of the finger controls and will see if it saves me anything.

Battery life has been good on mine so far. Make sure to turn the always on wifi scanning off! Made a world of difference for me.

On my first charge I got 6 1/2 hours with half on screen time playing games, surfing web etc. and had 50% left! My s4 would have died twice by now.

You should tell people how to do it. Wifi> advanced> uncheck always allow scanning.
I had totally forgotten about this. But even without if off I was getting 18 hours of heavy usage, no wifi and on lte. This phone, even without turning stuff off has the best battery life I've ever experienced from an android.

Getting the best battery life I've had with a phone. So far it's been on over a day with auto brightness, LTE, push email, and Wi-Fi when available and it's already hit 6hr30 min screen on. Plus there's 23% left?! Im impressed.

Severe Battery drain

So i am going to put this out there for some advice on what is going on. I've had my N3 for a few months and battery life has been outstanding. But recently it has been terrible. I use wifi most of thr day and I only have GPS on when I need it. I had an issue yesterday with com.samsung.indexservice using literally all my battery. Reboots and battery pulls did nothing. Then after a full charge last night I unplugged and left the house. These are my results. Indexservice is not using battery but something else is. I'm clueless to what it is. Any help is appreciated. I am not rooted and do not intend to.

Your battery stats will not be accurate until you drain more of your battery.
