iPhone 6 battery getting hot during charging
I've been using an iPhone 5S lightning USB cable to charge an 5, 5S, and a 6 connected to a computer.
I noticed that the iPhone 6s' battery got extremely hot during charge.
Then, when the 6 was connected I noticed that it actually was draining the battery.
That same cable would charge the 6 normally when plugged into a wall socket.
I switched the cable to the new one that came with the iPhone 6 and it works normal when plugged into a computer. No heat and it charges.
Not sure if there is a difference in the new cables or not, but I did get caught out and had to use a 30 pin with a lightning connector. It sat plugged in overnight in a wall socket and did nothing.
Is this a good question?
