12:57AM: Getting tired, so now will put headphones in and music on (Rdio app) until I fall asleep (which I never do, but for the sake of this test I am.) Still 100% as of 1:01AM. Been 28 minutes according to my Usage, which would normally have 8% drained by now 'cause usually I lose 10% per 30mins. So this is great!
1:03AM: music playing, head on pillow, shutting eyes now. (I'm hoping to fall asleep, then wake up around 9AM with music still playing to see drain results.)

Basically same battery life as first log way above in this post. Not sure if any point in keeping this 2nd log anymore since I lose 10% about every 30mins.
9:16AM: Assuming I lose 10% per 30mins, I'll have 1% in 4 hours, at 1:17PMish. I know I'll have my phone on standby a lot today since work, so I guess I'll continue with log.

So, from 6:48AM-3:34PM, I am left with 8% battery in all.* Now, as stated in the log, the Usage and Standby times weren't there since I charged phone while it was off.* But you can do the math, and so can I, sooo: 3 hours, 40mins Standby, then 6 hours and however many odd minutes.* I'm assuming Standby would be a lot more, though, since I was playing music on "standby" and when music is played on Standby mode, it counts as Standby and usage.* So those numbers are kind of rough, but the battery lasted about the same as the first log, before the restore.
So, please leave your feedback here of the post, how your battery compares, how you improved yours, if you've done tests, etc.*
Thank-you, all!
