    So lately my battery seems to be decreasing twice as fast as it was just a couple weeks ago. I'm using it the same amount of time as I used to, but its decreasing like twice as fast. Anybody know why this might happen or any solutions on how to make it last longer again

    Did you install twice as many things?

    Seriously... What did you change?

    Do you have any apps running in the background?

    I'm on an iPhone 4.0 with OS 4.0 (haven't updated either time yet)

    In the past 24 hours - my battery experience

    yesterday - full charge at 7am - 17 percent at 1pm. That's not using the phone but having wifi access and 2 email accounts pushing. Normally I would be at maybe 85 percent the LOWEST by that time. Did a hard reset and also reset network settings

    charged up last night and unplugged. Woke up to 54 percent. Reset network settings again and also killed my corporate email (which did have a server issue 48-96 hours ago). It's now 9:40 (2 hours, 40 min later) and I am down to 45 percent.

    Hoping that the corporate email having a glitch a few days back when reset was causing this problem to manifest - will know more later today...

    Very weird...

    This has happened to me twice in the last week. And never before.

    Once I went to bed at someone elses house with 70% woke up to a dead phone, and yesterday I put my phone in my locker at the gym with 50% and it was at 10% within 2 hours. Nothing was running both times, and the phone was hot both times.

    If it keeps happening ill return mine, but I used to get 6-7 hours usage with 1 day 10 hour standby normally. Now im getting 4 hours usage and 1 day standby.
