I'll happily post up a screen shot tomorrow for you to show the phones been on for over 24 hours.
Those who cant even reach 24 hours are either very heavy users, or simply havent set theirs up efficiently enough.
From batterytime lite the max you can expect is:
idle time 346:30 (signal will affect this)
Talk time 6:00
Video playback 3:26
Audio playback 6:29
Web Surfing 3:56
Obv thats exclusive constant use, so mixing and matching will effect this.
