[Q] short battery - Galaxy S II Q&A, Help & Troubleshooting

I'm having problems with my sgs 2 battery life.. I recently installed litening rom and did a battery calibration and usually my phone lasts for atleast a day and a half, but suddenly my battery began to have a short life, causing it to end after about 9 hours.. any ideas to why?
Thank you!

Post up your battery usage screenshot, and download betterbatterystats for wakelocks, sounds as though you have wakelocks without logs we can't tell.

To take screenshots just push simultaneously the Power and Home button.
You will find the screenshots on your internal sd card in ScreenCaptures folder.

Within app, press the menu button, select actions then Dump to File. It'll create a log file on the sdcard, copy and paste into pastebin or upload the log file.

I found 2 files after I did the file to dump, 1 is battery history.txt: http://www.mediafire.com/?71aqcz2kzl3xeh1
and the other is BetterBatteryStats.txt:

Highlighted in bold, main culprit your weather widget, kept awake for 30mins. Either remove those or decrease intervals. Other than that it's not that bad to be honest.
P.S you should update to a newer 2.3.5 rom, improved to 2.3.4, better battery life using another kernel as well like Speedmod.

Alright, thank you very much! one last question, how can i decrease these intervals as you said?
and btw, if I flash a new kernal do i need to perform a full wipe?

---

When I used Lightning I had the same battery problem, it only lasted for 9hrs MAX with normal use.
Installed this one and now it gives me 26hrs the most ! But still a huge improvement over the old F/W.

Kernel? No. Wipe both the cache.
Decreasing the intervals? Reduce the refresh time of the weather widget. If you don't use kies air. You could freeze it with TB.
