So which one is true?
You can't overcharge a phone, heck! I even put my phone on the charger ALL NIGHT, at least 10 hours (LOL) its connected. The USB charger turns on and off as necessary. Also, you dont need to charge the phone for over 8 or 12 hours, that was for prehistoric batteries of the 90s
What damages batteries is letting them discharge a lot like 5 or 10 percent.
Do a research about Li-Ion batteries, or any other Lithium battery and you'll find how to take a little care for those batteries. Basicalle: Never let the batteries fully discharge and do not overheat them. If you live in a very hot city like Mexicali, Phoenix, Las Vegas or any other place that gets temperatures up to 45 or more degrees celcius, avoid using the phone outdoors. (120°F)
