Thanks, the camera is indeed a real 5MP (GC5035) sensor and a 2MP (BF2253L) sensor.
It is unfortunately not easily possible to identify the battery capacity, the listed 1000mAh are the android default setting that is supplied to the device info tools.
One method is to check the battery calibration data that is used to calculate the fuelgauge:
- LEM12Pro ~750mAh
- Prime2 ~1500mAh
Please note that this values are not a perfect representation of the real capacity, they are probably the median result of the factory battery calibration process.
Then there might be some other factors like a lower battery cut-off voltage that could increase the capacity but also shortens the battery life.
Based on those references it is likely that you could add 5-10% more capacity on the listed values to match the real specification battery capacity.
