I had some problem with the haptic module that were soldered on the board (MetaMotionR) from delivery. It did not work at all at (since the soldering was not enough) I fixed this myself, but after some time it stopped to work again I had to re-open the case to fix this. At this time when I opened the case again and the battery cables felt of, and stopped to deliver power to the board. I soldered them back and now the board and sensors + haptic module works fine but the power percentage is very strange. At most times the percentage is at 6-7 % and after a charging of 12 hours it only goes up to a maximum of 27 %. The percentage does not seem to change in a realistic manner either... When connected to USB its at 100 %. I've done readings of the battery percentage with the MetaBase app on Android and Windows and the MetaWear app on Android. I've updated the board to latest firmware and done a reset. I've also tried to charge the board from USB port at a PC, Powerbank and charger, with different USB cables.
Can only the readings be faulty or is something broken?
