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.
Just my experience...
Help, my PC with Windows 10 won't shut down properly
Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
