Today, my phone was comepletely discharged for around and hour and when i came home I plugged in my charger to the outlet and i connected the phone. Then I realized that the phone is not turning or charging. So i plugged out the charger and connected to the different outlet and it started charging. So i was wondering if it was the outlet problem so i plugged the charger out again and plugged it in to the first outlet and was charging normally. So can this be a battery problem or even a phone problem? everything is working fine but should i worry about this? I also realized that some other people were having trouble with similar problem. Thank you!!
