Following this thread :
I would like to verify that my battery is indeed broken. It looks like it is charged as I can measure ~4V. But I guess something is wrong with the inner control circuit: when battery is “cool” (removed for few hours), the phone does wake up and start booting, but after few seconds, everything is switched off. My guess is that the battery (or the phone) decides that something is wrong and stops everything. The best way to verify this would be to use another battery, but that’s not an option as I don’t know anyone with an FP2. The second option would be (I think) to plug the battery to a resistor, measure the current and monitor what happens on the 2 controls pins:
- is it really possible ?
- does anyone know how the 2 middle pins should behave ? Are they standard ? Or completely FP2 specific ?
- would it be possible to use a battery from another phone (brand) and simply check that the phone works correctly ?
