My iPhone 3GS have been jailbroken with ipwnage tool since last july. yep - that's july 2009. I am currently on firmware 3.1.2 I have never had battery issues until lately (a few days ago). I realized that my battery life depletes a lot faster than usual. (i.e. down to 50% within 1 - 2 hours without doing anything specific) * i can literally see the percentage going down every minute or so. (i used to be able to last whole day without any problems) I am a careful user. I have bluetooth, GPS and wifi constantly switched off when i am out. no push for any mail accounts and brightness at 10% (with auto brightness ticked) As for jailbroken apps I have: - winterboard + Glasklart theme - boss paper - five icon dock - blue fire battery (battery mod) - SBSettings + built in toggles + 1 SBSettings theme - Quick Reply for SMS - Poof - OpenSSH - MakeItMine and thats it. -- as to why it randomly started depleting at such extreme rate lately.. i can only think of one major change i've made throughout the past few days.. since it was revision period so i played with my phone a lot.. (sigh, typical student) and i launched Cydia for the first time in a long while.. and realized that there were a lot of updates.. (like 6..) and since i was bored i decided to upgrade all of them. I am not sure as to whether this may have caused the problem. Obviously, I have also installed 3rd party apps.. but they are mainly games (i.e. We Rule) and random apps that don't really do anything. I have no multitasking apps.. i.e. backgrounder.. or anything like that. Anybody has any idea what is causing the battery life issue? It's a pain in the arse. and im often super worried when i am out -___- Any advice would be very much appreciated. Thank you guys! xoxo P.S. I really shouldn't have updated anything on Cydia since everything worked like a charm to begin with P.P.S. sorry for such a long ... 'question'. i tried to explain my problem with minimal words. .... fail i guess.
