yes, this is a "my battery's dying and i don't know why" thread, but this started happening all of the sudden yesterday so I'm trying to troubleshoot real quick. Earlier this week I left my fully charged iPhone 4 (4.0.1 JB) overnight, and it was at 96% when I woke up 7 hours later. Normally during the workday by lunch it'll have dropped to 85% or so. Yesterday at lunch it was below 40% with no out of the norm usage. I thought maybe it was the new LockInfo beta, so I uninstalled that, but didn't get any improvements. So last night, I fully charged it, cleared the syslog, and left it locked (screen off). Waking up 8 hrs later it dropped to 74%, had 3+ hrs usage, and only 1 new email and no push notifications (so I know that wasn't driving the usage). The following lines basically repeat over and over in my syslog:
full syslog attached. It has wake events of RTC and Baseband.
Any ideas???
