Samsung Galaxy S2 Battery Life not good

No offence mate but for a start you can search the forum and you will literally find dozens of threads on the very same subject which have been posted on here over the last few months.

Search and you'll find the answers your looking for, a tip freeze the Samsung bloatware in Titanium Backup and your battery life will improve substantially, there are many other methods to improve battery life you can find them yourself.

I get over a full day on heavy usage...

No offense taken, but most point to Rooting my phone...This is not an option for me at this time....I'll look some more, I guess...

Oh right well then your options are limited if your not going to root your phone as regards battery life.

I know...that's why I posted, but I should have said that in my original post...I'll edit it....but I did find something that I will try when I can..Phone is charging in a wall outlet right now, and I don't want to unplug it. lol...I do thank you for your effort and understanding...

I have unrooted phone and get around 17-20 hours heavy usage.

I would suggest you flash a 2.3.5 Rom via Odin as they seem to have better battery management if you haven't done so

you dont need to be rooted to flash new roms via odin

Also advisable to charge battery till full then use till its like 1% then recharge full and so on to calibrate it a bit.

Rogue apps can eat your battery life as well so If you can afford it do a full wipe and reset if you can and see if it makes a difference.

Looking into this one. Thanks!

all for my wife....she dont have data plan..


If her wifi is on and its constanly looking for wifi, will that be the cause? i just told her to turn that off.

What is a Rogue?

Chat applications like Google Talk or Facebook (if you go into Chat) tend to drain battery.

Sent from my GT-I9100 using XDA App

i have the same problem with s i9100 and when connect using my galaxy the battery charged very slowly but charged very quick in galaxy s
the battery in s i9000 more better

You guys need to give more information if you really want decent assistance, there is an app called better battery stats, you want to look at your partial wakelocks section in that particular app, go get it either on this forum or in the Market, post screenshots of your battery graph in Settings>About Phone>Battery Usage and click on the time, also a screenshot of your partial wakelocks will reveal the issue 90% of the time

Also, there is no need to root your phone to achieve good battery life, unless it is found that a system app may be the cause of the poor battery which is hardly ever the case, anyone who points you to rooting to get good battery life has very limited knowledge of android and what is the cause of poor battery life...

Usually downloaded apps and user settings are the cause of poor battery, there is absolutely no need to root to be able to fix those problems.....

I noticed this one too...My stock DXI2 room tend to be a battery hogger and the display consumes around 60% of my entire battery life...
