I charge z3c via magnetic connector on my bed time from 1.30am to 8am in the morning (about 6.5-7 hrs) it can be charged from 25 to 75 % only. Why does it charge too slow? Or I have to charge via micro USB connection. I'm afraid that if I have to charge via micro USB everyday, the cover flap may be loose and will not water-proof anymore..
Do you have any recommendation?
