The Minirig has finished charging but the app does not show 100% charge

So the Minirig has been on charge until the LED stops flashing. When you open the app and check the battery level, it is not 100%

1. Playing music will lower the battery voltage to give you a reading below 100%
2. The battery will be 100% charged, but due to component tolerances, the app is reading a lower battery level
3. Try charging the Minirig again to make sure it finished charging and the power wasn’t interrupted
