The 2000mAh's measured capacity
It's a long thread and someone maybe have mentioned this before but here is the data I got from the 2000mAh battery.
The readings comes from Battery Monitor Widget Pro.
Max. mV = 4196 (full charge, 100%)
Min. mV = 3288 (empty, when the phone turns itself off)
Real capacity = 1895 mAh
Not to bad. I've seen a lot of other battery packs(other than for the SG2) that's far from what they state in the spec.
The readings may vary from different phones and packs, and apps used.
Maybe someone has readings more closer to the stated 2000mAh for this pack?
