If you are having an issue with your battery, please make sure you are doing these tips to improve your battery life.
If you are still experiencing the problem, the next steps are to Clear the Cache Partition of the phone.
Turn off the device.
Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
When the Android logo displays, release all three keys.
An ‘Installing system update’ message will show for 30 – 60 seconds before the Android system recovery menu options appear.
Press the Volume down key several times to highlight wipe cache partition.
Press Power key to select.
Press the Volume down key to highlight yes, them and press the Power key to select.
When the wipe cache partition is complete, Reboot system now is highlighted.
Press the Power key to restart the device.
Your phone will take a little time booting up after the cache partition is wiped off of its contents as it will rebuild or recreate those caches.
The final step would be to do a complete backup and Factory Reset.
If the battery continues after this, please send a private message with your full model code and IMEI number. http://bit.ly/2XERsky
