I just now finished my second run it 'til it dies battery torture test. It really does seem to do some good with the calibration of the battery monitor, and the battery its self. I live in a sucky signal area, very remote. I drive into and out of service all day. When I'm at the shop I have a 3g network extender. I had at least one 30 minute conversation, and maybe 5 other 5 minute ones. Texts, emails, videos on youtube, 5 minutes of data sharing with my Surface, etc... The phone "unplugs" its self at 7 in the morning when my outlet turns off, and the phone shut down at 5:50pm local time.11ish hours ain't bad.
I was worried that the battery would really suck after reading threads like this one. I'm one of those who always carried a spare battery, I carry multiple pocket knives or tools, you know the type. (no pocket protector though) haha But this makes me think that I'll just get one of those emergency battery things that takes AA's and just carry that for the extreme emergency case. Otherwise my battery seems fine for normal use. Stay near an outlet when you need to do more stuff on the phone, or carry some alternate means of charging, and you're good to go.
