I don't know what happened different since I booted my phone yesterday at 7:00 am, but all of a sudden, my battery life has jumped significantly. I run the Seidio 1750. Yesterday, I went ALL DAY with normal usage (multiple texts, calendar appt reminders, a few brief calls with both wifi and bluetooth on constantly. My k-9 mail syncs with work e-mail every minute, and gmail wireless sync is on for two accounts) and I still had 81% battery remaining when I went to bed at 10:30 last night! I haven't shut it down yet just to see how far it will make it... Right now, my battery usage screen shows Up Time of 31:09 with Awake time of 4:16. I'm still showing 62% remaining battery!!! I'm wondering if one of the multiple automatic updates that occurred in the marketplace corrected a former battery hog (gmail maybe?) Anyone have any insight into this incredible improvement all of a sudden? I'm almost afraid to perform my usual overnight shut down and charge in case this is just a fluke occurrence. I'll post an update when I finally get a low battery warning to see how long she'll run on a single charge.
