2. The Umidigi S2’s Battery Gets Headted While Charging
The effective electricity that charges the battery only occupies half of the total amount which is used because the other half part is converted into heat energy.

- 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).

You may have opened too many background apps and functions. To decrease the power consumption, turn off unnecessary apps, processes and functions, e.g. Bluetooth, NFC, etc.
- Higher screen brightness can also consume more power. Adjust the brightness to a moderate level to reduce the power draw.
- The battery could also be suffering from the “memory effect”. At its boot state, fully charge the battery and remove the phone from the charger. Then fully discharge/drain the battery. Repeat this procedure three times. Next, reboot the phone into Recovery mode: long press the power button and volume up button together. Choose these options: “Recovery – advanced – wipe battery status”.
- If none of the methods work, it’s most likely a battery fault. Please contact the customer service for more help or return it back the factory to check and repair.

- 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. Different power chargers have distinct input / output current or voltage, so make sure to the original charger and USB cable to charge it.
- If the problem still persists when using the original USB cable and charger. Check whether one of them fails or not. Change another compatible USB cable or charger that has larger output current should be helpful.
