I think it may just take time to train the battery per se? I know that when you first get a new phone with a Lithium Ion battery.. it is imperative to actually drain it and charge it to full a few times before it stabalizes. I was a little concerned at first too, but I remember having to do this with my last phone as well.
I am on day 2 myself.. first day it hung at 5% for about 2.5 hours with constant texting/ GPS / youtube usage before finally dropping to 3%.. and then 40 minutes later it would not stay turned on any longer. I charged it to 100% last night and then powered the phone off when going to bed. I woke up.. turned it on.. and the meter has dropped down to 15% in 3 hours during usage, but I plan on killing it again and then repeating the full charge again tonight.
Will keep posting my results as well.
I agree with other previous posters! Please do call sprint and notify them of the quirky battery meter. They can probably release an update to help alleviate this issue.
Cheers!
