    Up until today I've been getting ok battery life(not great, but good enough to get through the day without a charge). Today I took my phone off the charger at 6:00 and it had 100% battery. By 10:00 (4 hours later, not 15)it had no battery left and turned itself off. In those 4 hours I texted for 5 minute, talked on the phone for 1 minute, and used Facebook for 2 min. The rest of the time it sat with the screen off in my pocket. I have Watchdog and it didn't notify me that any apps were causing problems in the background and I had a strong 4g signal.
    I am running Das Bamf 1.7 with the default kernel not overclocked with the on-demand governor.

    Why has my battery life been fine(12 hours, medium use) and all of a sudden gone to hell(4 hours, light use)?

    Any ideas?

    only thing that comes to mind is 4g. i was in the outer edge of 4g yesterday,so i turned it on. even with a week 4g signal i was getting 8-10mb down speeds and was pretty tickled. however,the 3 hours or so i had it on my phone dropped from 63% to 15% adn then i turned 4g back off :(

    i am using cm7,so my drain is prolly worse than most cases.

    if 4g is part of your normal routine and you dont experience that much drain,im at a loss... youll just need to check everything you can think of for something thats updating/syncing and suckin the battery down.

    this is assuming that you havent made any rom/kernel changes that could be contributing.

    did you calibrate the battery after flashing DB1.7?

    use the toolkit to wipe the battery statistics
    1) charge phone to 100%
    2) wipe battery statistics
    3) deplete battery completely
    4) charge to 100% uninterrupted

    do it every time you flash a ROM. if it's not a DB with toolkit, download "battery calibration" from the marketplace.
    doing so will wipe the battery stats file from your phone which can be erroneous when using different ROMs as it's based on your previous ROM usage.
