For the past week, I have noticed that when I plug my phone into charge (AC) it does not charge completely. I plug it in before bed when it is at 5% and when I check 6 or 7 hours later, it is only at 20%. The weird thing is that it says it's charging, but is actually losing power or just stays around 10-20% no matter how long I have it plugged in. I know the charger works because I have been using it for months and just last week was able to get it up to 100%. Another issue is the charger that came with the phone was not working properly. I would plug it in and have to wiggle the wire in order for it to display it was charging. this is very inconvenient. Any suggestions?
