Phone was in water or impacted ? if no you must detect is phone correctly detect voltage of battery if not then problem with
eeprom data's , eeprom , a/d converter in CPU , resistive divider near cpu , battery contacts . Battery I hope original :)?

I have heard that there is some resistor near the CPU. If this resisitor is desoldered the problem with the BATT is solved...
Is anybody knows which resisitor is this?

@CellM@n
What do you mean with "change resistor"?. Just remove it?. If it is really a change then, what's the new resistor value to solder?
