3 hours has passed, and here is my report about the battery life:
My SIII/Predator combo had been playing music from 13:05 to 16:05, the music files are FLAC, 24bits 44.1 kHz which i think the Neutron player has automatically resampled them to 16 bit 44.1 kHz. My phone is in 2G mode, with the wi-fi on, no phone call or texting during this 3 hours, and most of the time the monitor was off.
The result is the battery drops from 86% to 61%, so it is 25% in 3 hours...
some more details:
- I turn my wi-fi on mainly for e-mail, refreshing every 30 mins
- My SIII is quite new, so as the battery, has been used for exactly 2 weeks only
- I switched on the power-saving option in the Neutron player, but i don't think it made much difference in this test as power is saved from simpler UI
- The battery performance was measured by built-in function, the accuracy is doubtful...
