Done charging (green light) 4.19V
Waited 2 hours 4.17V
Plugged in phone 0.00V no connection for some reason, unplugged from charging board, 4.18V found after fiddling around for a few seconds, plug it back in
Charging phone 3.85V
Drops 0.01V every 60 seconds until it gets to 3.65V then drops out altogether down to 0.00V and phone stops charging
Total charge time ~ 10 minutes
I still think theres an issue with the battery, is there some other way I can test it?
