Nexus 7 battery saving - Nexus 7 Q&A, Help & Troubleshooting

I wanted to ask does the wifi turn off when I lock the tablet? Or it stays on?
Also, has anyone tried the Juice defender app? It works great on my phone but don't know if it will help with Nexus 7.
Thanks.

Poll: Wifi only N7.. Keep wifi on during sleep?

With your wifi only N7, how have you configured the "wifi on during sleep" setting?
Personally i chose never because i rely on my phone for notifications and my N7 stays at home at all times, so no need for wifi to be on all day.
I'm set to always, as I often leave things downloading while I do other things.

I'm also an always on'er. Battery life is good enough that I don't find any issues with it.

I set it to never. Phone for notifications etc. If the n7 is around just pick it up and use it.

I had tried the never rule so that it would switch off during sleep but it seemed to stay awake. But now i use automate it app to switch WiFi off when the screen goes off, with a 5 min delay, its also set to come back on when three screen is switched on again, works perfectly.

However I remember some 3rd party battery apps show correct info despite the info under settings.

I think this is because android OS is designed to work as a mobile operating system (not turning it off unless there is no battery) so that's y after using ur tabler when u turn it off it resets the time or add a significant difference.
I don't turn off my tablet and most of users don't so that's y ur only having this problem.
Besides tangby time on nexus 7 is amazing 1%-2% drop in 12 hours.

The only time that Android should be resetting battery stats is when you unplug the device after an approximately full charge

Cache Update Service not letting phone deep sleep

It is a Google service and I have disabled location services and Google Now. Does not seem to make a difference. I have looked everywhere and have come up with nothing. I have the phone set up basically the same apps as my N4 and my Nexus is crushing my G2 in battery life. Any ideas would be great on what is causing this.

Are u talking about google service that you see when you go into battery usage options? If yes, im in the same boat as you.
What percentage of battery doew the google service use?
I would like to know how to take care if this problem as well

I am using better battery stats and it is partial wake lock I guess I did not bother looking at the overall usage. I am trying a few more things and will report back later.

add me to the list of people this is driving nutzo.
Question, when you go to google sync under settings/accounts and sync, does it show that 'sync is not available at this time?'
I wonder if that could be causing it?
I am waiting for my case to make it my daily driver but last night I tinkered and went and set up all my Google apps and changed my Google plus photo to only upload on charger. When I turned it off it was deep sleeping and and that wake lock was no where to be found. If anyone wants to try this and see if it helps.

[Q] Nexus 4 turns on randomly in pocket?

My nexus 4 has had some curious behaviour over the past few days. Sometimes I take it out of my pocket and the screen is on, and its in an app, or my pie mode has been activated. I noticed that 9/10 times my Bluetooth turns on
. this isn't a big issue but it drains my battery. Help is appreciated. (I'm running PA atm)

Nexus 7 screen doesn't rotate

I'm running cyanogen 11 nightlys. My screen no longer rotates. I've checked the settings and rebooted, but can't figure out the problem. Anyone know what might be going on?
