Updated to iOS 5.1.1 - Battery now lasts 4 hours or less
iPhone 4, Black.
Has anybody else had this problem?
Since I udpated to iOS 5.1.1., my battery drains like a fiend. I've sat here and watched it lose 1% every 2-3 minutes at times.
1. I've already closed all my background apps
2. I've already rebooted
3. I've already drained the battery to 0 and recharged to full.
Prior to 5.1.1, my phone would last all day (from 6am-10pm) with normal usage and only be down to 60% or so. If it's charged in my car at 100%, by the time I walk 3 blocks to my office it's down to 93-90%. I've also noticed that the back has been warmer, as if I was using a heavy app, even though nothing is running.
I don't think the physical battery decided to start dying at the EXACT moment I installed the newest software update, amirite?
