Phones and small tablets might overheat if they are not plugged into their dedicated chargers. If you plug them into a powerboard usb then common sense needs to prevail and you check your phone or small tablet. Same thing if you are charging off a computer. The dedicated chargers generally do not seem to allow the phone to overheat . If you are having trouble charging your battery, before you go out and buy a new one, try trickle charging it. That means you need to use an older charger or the usb connection in your car. They charge more slowly and so will often get the charge started and it might take forever but hen you will be able to charge the battery normally. For more information about phone batteries go to lifehacker. Batteries are just not in the same league as the technology we are using. Eventually they will resolve this battery dependence but , until then, stay informed, keep calm and charge away! Experience is a great teacher and by now we should have a lot of information about smartphone maintenance. I find they warm up if you use them while they are plugged in. Same with smaller tablets. They just want to charge and multitasking is out of the question.
