repost for better attention:
btw...as for battery problem

i notice a new problem

last time we had standby time = usage time

now I experienced that this usage time on the phone is actually longer than the time I had spent on the phone

eg. Fully charged....I open and use for a while (less than 1 minute)

I put it into standby mode and after a while I open again

the usage time will become like 1-2 minutes even it's sleeping

somehow smtg is running in the background

it's normal..its not caused by any cydia tweaks or what..the 1 or 2min was used to keep your telco's signal connected..unless u standby your phone in airplane mode after fully charged..then u wont see the 1 or 2min used even u din do anything
I've tested this myself personally btw, I used to restore my phone last time when I encountered your problem I thought something must have went wrong, I left it standby right after fully charged on a clean stock ios..no one sent me msg or called me during that night but it showed my usage time around 10+mins after I woke up..asked around, till then I found out its just that the phone needs to keep itself connected to the signal, so the phone wont let itself completely 'sleep'..some processes is still running even u sleep your phone, else it would be airplane mode, ..Hope this helps you
