[Q] Help! Battery While Sleeping

---

Long time lurker, first poster

So the quick/dirty is my tablet's seeming to loose battery rapidly during 'sleep' (hit
power button, screen off). Not always, but sometimes.. Atleast ~10% per 8 hours, about 20% in ~3 hours in the attached BetteryBatteryStats (was away, didn't touch it, went from ~42% to 22%), is this normal?


The first time I noticed it the tablet was at about 72 pct (then I slept), 8 hours later it was sub 30. My phone was next to it in comparison went from 98 to 92 during the same period.

I've not rooted the tablet but I installed the GoLauncher, nothing in the battery stats (attached) seem to jump out at me, other than the WiFi waking it up 291 times?

Do I need to manually disable WiFi every time I hit the power button?
What kind of idle times are you guys seeing?

I'm pretty sure if I left this sitting for ~34 hours it'd be dead, seems kinda crazy that it can't get better standby time then that, my Droid Incredible sitting idle can last at least 3 days and that's fetching email and facebook messenger. In fact I think that's a deal breaker and i'll be returning this thing if I don't see improvement, the tablet's a quick/handy thing to use now and again, but if I have to wait about as long as it takes my laptop to start up (full bootup) then I don't see much use.

I had a similar problem. A full day of light usage and it's down to under 50%. I had to charge every day. Battery usage said it's mostly the wifi.

So I installed "Juice Defender plus" ($2) from android market. And set it to let the defender automatically enable and disable wifi, plus let it auto disable wifi after one minute if it's not connected to a network. Also set it to disable connectivity in the middle of the night.

After nearly 2 days of slightly above my normally light usage, the battery is still at over 70%.

please check the other thread regarding the battery life. I did a factory restore, and it seems to improve battery performance.

I'll give that a shot and report back, kind of a pain to have to do that after just a few days, worries me long term

In regards to the Juice App, i'm not really interested in rooting ATM, not sure if i'm sold on this thing yet, the potential is there but there are several things I just can't get used to on it yet, like navigating around apps (lack of back button, bar being on the bottom), and terribly missing the optical sensor (droid incredible) and auto complete. And B&N's App Store is a pretty sad sight in comparison.

At least on your last point, one of the best reasons to root is to gain access to the android and amazon marketplace. Forget the B&N store, except for maybe books.

Disabling the BN cloud service seems to increase the battery life a lot. I used app quarantine to disabled the service.

What do you have syncing? I have nothing on this except Go Launcher, Amazon Store, Solataire and MXPlayer. No email or social networks going and mine lost 4% while sleeping for 8 hours.

We had a problem almost exactly like this when the first GB kernels were being ported over to the SGS. The solution was to toggle the WiFi sleep policy to anything then set it to "Never."

This should help with a lot of the wake-up/plugged-in drain that you are experiencing.
