Just a guess, but it might not be that the wifi is the problem, could be because some apps are trying to connect to the wifi.

Seems wierd but my battery lasts 2 to 3 times longer on wifi than without wifi turned on. Anyone think this is right?
Yes that is correct 3g takes more battery power

Hi guys,
Is anyone else get terrible battery life with 3g and data on even on standby? I believe the phone function drains the battery and it lasts only 2 days or so on standby. I constantly have the tab on flight mode with wifi enabled and battery is much improved to about 1 week standby. Anyone else? I am on stock 4.0.4.
Thanks
Wtf r this guy even serious? I wish i had 1 day standby, what a joke

Hi Iong. We are talking about a tablet here, not a phone. Tablets should have 1 week standby at least. The battery drain with 3g and phone on is unacceptable. I think the reason is the connection to phone signal which is constant.
Mate 1 day pr 2 day standby is a lot, given the fact you install many program and it constantly connect to tinternet to check for updates notifs etx. You dont have 1 week standby whatsover, forget it. Big tablet big baterry big screen. Ot all goes scaling together

So 'l2_hsic' and 'batt_work wake lock' are the 2 processes keeping my table awake for 5 hours in total since yesterday. Any idea of what these do?
Thanks

most likely is that one or more of your apps is causing the problem. try a reset and see if the problem goes away. if it does, install apps one by and and check which one is the problem
Use juice defender ultimate in tablet mode. I can go several days idle time and lose almost no battery.

wow guys are you all serious??? i lose around 10-15 percent overnight man
Dude.. My phone was on 60 percent at 6pm once when I slept... Next morning at seven it was off... Wifi off data off.. All **** off... I dint even get a call or msg... Definitely not 1 percent I guess...
If I leave data and WiFi off, about 2% to 10% but that isn't usual. When I am home, I leave WiFi on and that gets my currents and YouTube video preloaded. 15% to 20% Max. I rarely leave it to charge overnight.

REBOOTED - nothing, drain battery like hell, lose about 30-40% in 5 hours...
I woke up with 15-20% battery drained... wtf guys ?
I kill all apps, turn of data, wifi and etc, still nothing...
BATTERY STATUS - messaging use 84% of battery... wtf ?
To all of you having problems with battery drain, you should know that last Google Maps update messed up the deep sleep state of the system.
I´m running Carbon ROM, but also tested with other 2 ROM´s and the results were the same, around 20%-25% battery drain over night.
I read that disabling "Reporting Location" and "Location History" under Location settings in the Google Settings app(the one with the green icon) helps a little, but still is an issue.
With these settings disabled, I get around 5% battery drain over night. Although the wakelock has decreased, is still there waking up the device. Already reported to Google to see if they can do anything to fix it. The wakelock appears as "Android System" or "Google Services".
Before update I had around 3% battery drain over night(around 8 hours) with WiFi.
Hope this helps.
:fingers-crossed:
As a battery life druggie, I get 1% max. Regardless rom. Usually wifi off and 2g data on. (wifi on is bad for HUMAN DEEP SLEEP).
A not sure useful or not hint, set pm.sleep_mode=1 in your build.prop
Disable everything you can think of. Wifi, gps etc.
Uninstall bloatwares, replace with downloadable ones, use greenify to freeze them.

Just curious because I lose about 7-8% overnight and I feel its a bit much. Feel free to share your results.

Doesn't it depend on widgets and how many apps are using Push?

0 for me. In fact, the battery gets charged to full over night. I put it on the wireless charger by the bed right before I go to sleep. :laugh:
My device sat unused for two nights and it only lost 6%.
i lost yesterday about 4% in 14 hours. do this ** settings- wifi - advanced - keep wifi on during sleep - only when plugged in ** you will see huge battery improvement. also you can use greenify app to hibernate apps that wake you tablet during sleep

Just wondering.. Is your auto sync off too?
Mine has been very good. Been unplugged for 7days 12hrs, WiFi on the whole time, couple hours of screen on time and still got 20% left. Overall I'm happy.

nope my Google location service, gps and auto sync on. but if u keep ur wifi off while screen is off auto sync will not work then when u turn ur tablet on wifi gets connected you get all the notifications. no point to get notifications on tablet while im getting those notifications on my phone. also ive noticed that the more you charge the battery it gets better

Ditto. However, I did forget to plug it in one night an it was about 2-3%, FWIW...
Ever since switching from an iPad to a Nexus 7, I've noticed some terrible standby battery life. Like losing more than a % an hour. Currently have WiFi off when screen is off and all location services are off...is there something else I might be missing?
Thanks,
Will

Is it rooted? You could try the greenify app if you want, now with the new update it works with non rooted devices but has some restrictions.
Look after your active backgrounds processes.I rarely lose battery when screen is off.
make sure tablet is actually in 'deep sleep' use cpu spy plus or betterybatterystats to check wakelocks
u should be over 95% deep sleep if your not doing anything after 30mins off/on standby
in 8 hrs off, u should only lose like 2-3% max , and deep sleep = 95-97% or higher
