Can you guys post any apps that you know will drain battery?
After I upgraded to 4.1 and Jailbroke it, I decided to hold back on my CYDIA paid apps to observe battery life, and it is definitely longer.
Before I couldn't last a morning without recharging.
The essential cydia apps that I used are
1.) Lockinfo with (HTC weather plugin, appigo todo plugin, twitter plugin +built in stock plugins)
2.) Android Lock
3.) Winterboard (Black Ups theme)
4.) Winerbboard Slanted Clock Lockscreen (With weather)
5.) SB Settings
I am not sure if it is the weather updating parts or twitter updating on lockinfo that drains the battery.
Will be testing them one by one soon observing battery for a couple of days.
