The effective electricity that charges into the battery only occupies half of the total amount because the other half part is transforming as heat energy. It's a common physical reaction.
● Once the phone is fully charged, but you don't pull it out from the charger. All the electric power will all transform to heat energy, sure the phone will become hot.
● Do not play the phone while charging, it will release abundant heat. Also, stop over-charging the phone, which will damage the battery.
● The most terrible situation is that the battery is damaged or aged. When the heat is extremely high and expanded, please stop charging it immediately and leave it away! Wait until it cools down and take it to a local phone fixing store to check and exchange the battery (replaceable battery phone).

● Do not play big online games / listen to music / watch movies while charging. They are not only will slow down the charging speed and may shorten the battery's lifespan.
● The power charger is not an appropriate one. The different power charger has distinct input / output current or voltage, so make sure to the original charger and USB cable to charge it.
