Since I don't have permission to post in development forums, I will have to ask here. Just NVFlashed to Prime 1.4 then upgraded to 1.9 and everything works great except now I notice that the Wifi to shutoff when screen is off does not appear to work. I know this was working in the stock ROM. Is this a known issue or something particular with mine?

I have the same problem and I have checked the sleep policy multiple times. I have even changed it to never turn off then back to off when the screen turns off then proceeded to reboot the device. I still have the issue though.
Yep, seems i am getting this same issue seems wifi is on all of the time.
Yep last night the battery in kb went from 65 - 3% in 10 hours while in sleep. Says 43% of battery use is wifi. I did read somewhere that it was said to be the latest google maps update causing it but I uninstalled those and it still does it. It does appear to be going on and off like some other people have describe. I am pining it from desktop and every other time it starts with 3500 ms ping time then the last 3 are normal.

And Today I fully charged both KB and Tablet then turned on airplane mode and left in standby all day. Its 8hrs of uptime and only 4% battery drop between both. Not a deal breaker or anything just want to let someone know before 2.0 comes out to see if maybe theirs an easy fix. I will ty to run fix permission in CWR and recheck.
Anyone experiencing battery drain on ICS? I upgraded, rooted, and removed some of the bloatware to help. Thought it was fixed but my tab is dead again. Says the Android OS is taking up my juice. Was never a problem before. Could leave it on standby for days with HC. Now its dead in a day or less.

I initially saw similar behavior, but once I killed the cached processes once, and since have shut down to charge and started new, I haven't seen that behavior.
Do you have WiFi on? Could it be you have apps that are checking to be updated? I know in the past on my phone my Amazon Appstore has a habit of starting itself up and continually checking for updates for itself and for any apps I got from Amazon.
Tried it both ways...wifi on and off.
Try using CPU spy (free in market) or betterbatterystats (free- search for it here on XDA) to see what is eating up your battery exactly.

I noticed that I had a conflict between "Power Savings" settings and the "Display" settings. Putting them both at 1 minute resulted in an always on screen I had to disable the Power Savings to correct the problem.
I did have something odd happen yesterday that seems to have kept my screen on for 4 hours. When I got home and opened my case the tab was very warm, and shut off. And all but entirely out of power, before that it has used about 10 % in 17 hours of standby with about an hour of use, or so.
I think it is possible that an app that previously didn't keep the screen on is now for some reason keeping it on, and I didn't notice when I closed the leather cover.
No issues today, but I am going to try and see if I can find some release notes to tell me about the new download for ICS for the P6210, perhaps this is addressed?
Just to update I installed the betterbatterystats. I showed a couple of things that were keeping my tab awake. Once I fixed those I thought that would be it but it was still draining. I then installed juice defender and had it turn wifi off every time I turned the screen off. That did it. Was never like this before the update but at least its good to know I fixed it.
i suggest checking better battery stats for AudioOut_1 Partial Wakelock. its been draining my phone fast when i upgraded to ICS.
check it here: http://forum.xda-developers.com/showthread.php?t=1629346
now my battery is working great.. i just left my tab for 10 hrs in the locker when i got the tab its still have 97% battery.
for me i just checked and changed my wifi sleep policy from never to when screen turns off and its fine now. :highfive:
I thought about this very issue; I decided to wait.

Did you download the ICS as opensource? Myself, I am deciding to wait for the OFFICIAL verson to be released.
I had the same problem. i even went back to HC to make sure
the issue is not there (it wasn't) and upgraded to ICS
again (full wipe all the time). No luck something keeps
my device unable to go to deep sleep.
Now i'm back at HC again

The version is OFFICIAL .
It's just available only for some countries.
i had the huge battery drain issue while in stock ICS..
the tablet simply refused point blank to go into deep sleep.. in HC it would but not in ICS.. i would take the tablet fully charged to work and not use it much there.. by the time i was travelling back it would be 60% drained in not using it througout the day...
recently flashed to aorths CM9 build and all my battery woes are gone.. now when i get back from work the battery is at 96%!!
battery drain during usage is the same but the CM9 build has awesome battery conservation stuffs for when you dont use it..
would suggest everyone who has these battery issues to move to CM9.. really helped for me.
My battery usage on CM9..

Early results show Juice Defender is helping a lot with mine too. Thanks for the tip!
Next morning: Just the free version of Juice Defender using the default profile took me from 35% overnight drain yesterday down to 3% overnight drain today. That's not bad. It should be even better tomorrow because I've turned off all location services after seeing that BetterBatteryStats says Google location is the worst single offender at keeping wifi going overnight.

Could you tell me how you "killed cached processes" please?
I am having similar battery drain. I am in the process of completely charging battery after it drained 40% in sleep mode last night, wifi off in sleep mods, notifications off, sync off.
I have already done a reset to factory, tried draining battery, and recharged in off position.
Nothing is helping so far. I have installed better battery stats, and CPU spy this morning, and will have data tomorrow morning.
thanks for any help

I had the same exact problem ever since the stock ICS update. My Tab Plus is all stock, no mods at all. The battery would completely drain after one day, and I have very little on the Tab Plus. Nothing helped at all, so I finally bit and did a factory wipe. The battery drain stopped immediately, so I started changing the settings back to the way I like it.
Then, next day the battery went completely dead again! I back tracked and figured out exactly what it is which makes absolutely NO SENSE - turning off wifi in sleep was what was draining the battery! See my screen captures. Notice on the first screen shot, as soon as the wifi stays on the battery drop bar stayed almost flat.
I observed a similar behavior on my 100% stock AT&T GS3 phone also, turning wifi off during sleep causes more battery drain.
I'm getting "suspend backoff" under kernel wakelocks which is preventing my tab going to deep sleep when unused. Everytime I wakeup in the morning my tab is dead. The only solution I found was to turn off wifi if I'm not using it. Anyway fixing this?

I wouldn't believe someone actually pulling a month on a single charge (since that is what a 20% decrease in a week implies!). I run about three days on a charge, and that's with the dock attached. (EDIT: I can easily drain the tablet+dock combo in a few hours of heavy (graphical) use.)
You can join in here:

to see if there's an app going haywire. Most of the actual "bad battery life" cases have a rogue app.
well this person said it wasnt on screen off time. noooooo use
Stand alone tablet without dock? And WiFi on or off? If WiFi is on and it's standalone tablet 20% seems to be fine for a whole day.

With everything off (wifi off, gps off, locationservices off, maps disabled, static wallpaper, no moving widgets, apex launcher, etc) and on standby without ever touching it, mine has dropped 4% in 29 hour.
So it is possible.

Well, it's meivakantie, so I've been home mostly. I've been way too absorbed in Divinity 2 xD Which means I'm on my laptop most of the time (except now, I have to pick up my ID card at the police station. And no, I haven't told them I know their WiFi password is ' Politie.'. :laugh: Do they have to prove their stupidity at every possible opportunity?)
I do have some widgets (Zooper 2x and 1 Eweather HD.) But they're both set to update manually only.

Using 4.1, I was getting results similar to yours. Since upgrading to 4.2 though, it seems to be more like the OP's.

Still on 4.1.2. Considering all the mentions of issues with WiFi, Battery and other, I'm a little hesitant to update to 4.2. Also, it looks hideous.

Hmm? Looks the same to me. You mean the new default launcher that ASUS thankfully doesn't ship with by default?
Same as OP
I have the same problem as OP with 4.2 but I have the keyboard dock. I can leave my tf700 for 2-3 days without using it and come back and its dead. This is from a 80-90% charge. I think there must be something with the deep sleep not kicking in.
I am thinking of looking back at the build prop to see if that helps with deep sleep. I have wifi off, gps off, brightness down. I did have location services on but figured I could so that's news to me and the only other thing I have is a moving wallpaper. Could those to really be causing all this drain? There has to be some way of getting deep sleep to truely sleep deep and shut down everything..

New app to help with deep sleep
I just installed DS battery saver pro and I am hoping it will actually help with deep sleep. I had power switch but it did nothing but pop up and bother me and never actually shut anything down. I am hoping this app will actually do what it says it can do and shut down all apps and everything when the screen is off.
I am having the same problem since the 4.2 update. I charge my tablet+dock and after 2 days of standby ONLY - no more juice. Everything turned OFF, never touching the tablet.
Any way to downgrade back to 4.1?

Yes, you can just flash the 4.1 firmware to downgrade. The 4.2 bootloader works fine with the 4.1 rom.
Don't forget to wipe cache and dalvic. If you have problems afterwards you may have to do a factory reset and re-install your apps.
There's a guide somewhere, I believe in the General Discussion section, on downgrading.

Nope - everything fine here. The battery seemed to drain very fast after I flashed the first 4.2 rom. But after a few charge/discharge cycles everything seems to be honky dory.
Took a fully charged tablet/dock off the charger about 16 hours ago. Did the usual surfing, reading the forums, email etc, watched a couple of episodes of Breaking Bad, downloaded the latest Cromi-X rom and installed it with mods - I would call it a day of light use.
The dock s now at 9%, the tablet at 90%. :thumbup:
Your battery calibration may be totally off. Have you tried this:
Let the tablet drain to almost 0%, connect it to your PC via USB cable and make sure the PC is on and not going to hibernate or sleep. Let the tablet trickle charge all night - at least 8 hours.
That seems to have helped in some cases....

After I unlocked the bootloader and rooted the phone it started draing quite a lot of battery, moving from 100% to 85% in less than an hour. Is that normal ?
Is that with the screen on? 15% per hour is normal playing games or watching movies.
Nuthin' but a 'Moto G' thang
Screen was not always on i used it normally didn't play games or anything. Maybe it's because I only xharged it twice does it need calibration or something ?
Unlocking and rooting wont have a direct impact on battery usage.

Have you checked for wakelocks. You could use CPU Spy to make sure your phone is entering deep sleep. 15% battery drain in one hour in standby is not normal.

factory reset - always worth a try. Or wake lock detector to see what's keeping it awake. I had issues with battery when I switched from one WiFi network to another and no wake locks showing. Factory reset magically fixed it.
See here

I know your device is brand new but I'm sure some junk sometimes gets in cache or something like that. Think I'd be inclined to always factory reset a brand new phone now.

Battery drain app might give you some ideas, I'm averaging 0.85% hour with location and google now on
https://play.google.com/store/apps/details?id=com.WazaBe.android.BatteryDrain
There are threads and a bug report with Motorola regarding this. It seems sometimes once GPS is used the battery continues to drain at 1-3% per hour until you reboot.
It may not be the issue in your case but it looks likely as the drain you see when the phone is not awake looks very similar to the problem.
If it drains in airplane mode and the phone shows as never awake then its the same problem.
For now don't use GPS or if you do then reboot directly after.

If you are getting the weird drain issue that seems to be related to GPS then maybe best to use battery saving. Depends his bad you need GPS though. So up to you really.
battery drain around 2.5 % /hr . Basically havent been using phone after 82%
