Thank you everybody. It is obviously something else, because it has gotten significantly worse. I turned vibrate back off, and even so, ten times worse almost. example: in 23 hours, my phone dropped to 3% and I had only made ONE 5 minute phone call the whole time, and also swiped to unlock as I had a reminder at 2 PM which of course I forgot to note since the phone is all quiet now, but it was only 1 hour later when I swiped the reminder off. (could that be any kind of cause? using reminders and not unlocking the screen to note that right away?) But still, midnight I'm now at 28%, again, this is ONE small phone call as the sole usage all day! and left it uncharged just to see, and 3% by 6:30 AM! Next day, I'm watching it drop 10% in 1-2 hours. It varied, but no usage at all. And this time I turned all location services OFF just to see. Battery life was better than the day before, but still, to come home and have it at 50% is ridiculous with again one little phone call. (my job is hectic-I'm in later today). On weekends, my phone gets a good workout, and even then, it wouldn't be at 50%. Most of the time with the very minimal use it would still be in the low 90's of percentage. Any ideas at all? And I have NOT done the software upgrade to 5.1.1 either. I read about battery life issues and decided to wait. And what a laugh because now I'm having my own horrible battery life right after the release-pretty ironic! Any ideas/suggestions? Back it up and restore? Back up to the Cloud or iTunes and restore?
