I am using the stock battery, an unlocked boot loader with the phone rooted. I have not removed any applications (some consider bloat-ware). I have taken the time to completely cycle the battery 3 times now. I use the Juice Defender (free version), have the screen shutting down after 2 minutes of non-use.
With modereate use such as 1 or 2 TV shows streamed, some texts, email and occassional browsing I am getting 12 - 14 hours a day.
With heavy use such as 3 - 4 TV shows streamed, lots of text, file downloads and uploads, lots of streamed music - I am getting around 6 to 8 hours....
Overall, very good performance for a smartphone....... :icon_ lala:
