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

Just got the phone yesterday and won't even get into the atrocious battery life but my issue is in the stock 2.3 battery graph wifi is shown as being on the past 2 hours but I had it on about 5 minutes...
And for about the past half hour no data of any kind has been turned on

How old is the battery? You can pick up OEM Samsung replacements for like $7.00 on amazon. I have 3 myself.

Have you tried using a different kernel? Matr1x and marmite work best for me!
Well running pacman rom with matrix so gonna see how that does

since you're talking about battery issues, idk if this is "normal" or not, but just now, my battery was at 38%, so i started to plug it in, tried doing a reboot and when it finished rebooting within seconds, all of a sudden, the battery jumps up to 60%...i think my phone's battery is fu**ed up

that always happen to me too ... deleting stats isn't usefull ... maybe it's a battery problem ... my battery isn't perfect but it can make about 2 - 2.30 screen on time and a total of 14 hours all sync active ... a newer battery could give me probably some more juice
Yea same result running matrix so I think its the battery
Hopefully.....

I forgot to mention that my battery was replaced a few weeks ago!

using straight aosp 4.2 with any kernel gets me at best, 5 hours of standby time. I noticed this about a month ago and immediately started looking for ways to prolong my battery life. What seems to be working best for me is disabling mobile data when I'm not using it. Just this one setting gives me a boost from 4-5 hours in standby to well over 12 hours of normal use (of course, with the exception of any web service). I have come home from 13 hour shifts and still had 30-40% battery left several times!! However, this only happens if I disable mobile data.
Something needs to be done....and QUICKLY!!! My phone is pretty damn well useless for anything involving internet connectivity unless I'm using wifi
btw, my battery is about 14 months old.
I'm pretty sure the battery drain is from 4.2, when I was running 4.1 I had no issues
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.

may be change firmware?
i only manage to use it for about two hours after a full recharge ..i only tether my laptop on my cellphone with 4g connection..other battery sipping settings have been turned off including background data
how about you? is this normal?
Yes this is normal even though I think my battery only last about an hour and half maybe because im using apps on my phone too.

To see how long my battery would last with Wi-Fi and mobile internet was off, would last I charged it to 100 % then after 3.5 hours had a look, it was down to 93% but to my suprise Wi-Fi had used 12%! Does any one have any ideas how?

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.
