Improvment battery charger visualization:
In the previous version the green flash (charge complete) was shown even battery had not reached 100% charge. Root cause was that the pin signaling the end of charge could be raised for other reasons then a full battery. The new version will show the green flash only in case the battery is rated as full.
In addition the graph visualization has been updated to continously progress. In the previous version it only progressed in case the charge value changed. Especially at charging start the charger is doing some battery evaluation which does not increase the charge state. In such a case the graph seemed to be frozen.
