    After upgrade to 6.15 BB and 4.2.1 firmware, my 3GS's battery drain like crazy!! I normally have the 3G, WIFI and BT on, push off. From 100% to 55% only take two hours!!

    Any idea? This can't be normal, I muse miss something here!:confused:

    Not sure what's hacktivate, I JB and unlock it for use for my carrier. I keep all the setting the same as 4.1.

    Did you restore your phone from backup? That's the cause of most battery drain issues, in my experience.

    Restore the phone as new device with a custom firmware. Don't install any other stuff and test battery life.

    restore as NEW and don't hacktivate...

    I'm on 4.2.1 but w/ the old BB (3GS w/ old bootrom) and my battery has been fine, the signal seems to be not as strong as before though... Has anyone seen their signal strength drop down a little also? maybe that's what's causing you to drain your battery more to find better signal...

    yep. same issue with the battery on the upgrade to 6.15 BB and 4.2.1 firmware.

    battery is gone in less than 4 hours. My screen brightness is really low too.

    Reminds me of the original iphone!

    Im not using an official carrier and gotta look into the other software to download.

    turned off notifications and its not draining the battery as fast now.

    Still happy to have my iphone working unlocked. Thanks Dev-team. A hero's work is never done.
