How long should it take for a 16gb Xperia Z tablet to fully charge? Ours charges VERY slowly. We have tried diferent cables without luck. Last night before bed, the tablet was at 47%. Charged it overnight (7.5 hours) and it is still charging at 94%. Is this normal?
If the battery is completely discharge, the Sony Xperia Tablet Z charge by 20% every hour, which means that it takes roughly 5 hours to completely charge it. Did you get any battery notification status in the past that would indicate a fully charge battery? Have you tried charging it with the device completely powered off?
