Just recently bought the 1930mAh battery from ebay and gotta say, it is pretty damn good.
The values below are from normal/minimal use. Will do a heavy use test after to confirm that.
Been on 21 Hours and is on 90%
Been on 46 Hours and is on 80%
Been on 64 Hours and is on 70%
Been on 74 Hours and is on 60%
Been on 88 Hours and is on 50%
Been on 95 Hours and is on 40%
Been on 120 Hours and is on 30%
Been on 127 Hours and is on 20% - Hmmm, anything over 35C, with use and this battery drops like a stone, was in a very warm place at the time lol
Been on 136 Hours and is on 10%
Been on 141 Hours and is on 0%
Not bad result from my end to be honest. 141 Hours normal/minimal use.
Takes 2Hours 15Mins to charge....very simular to stock battery!
Stock battery heavy test result: 3 hours
Gold battery Heavy test results: 5 hours
Firmware im on is JPY - Insanity v0.4.0 ROM
many more sellers on this guys, so plenty of stock around.
Its the same size as the 1500mAh one which is nice, didnt fancy a bigger phone lol
