Now days am charging phone in a day 3 or more times .and full charging time are increased that time phone are over heating too much when am charging not using any applications in background Wi-Fi is off but phone getting more heating
Deactivate Bixby voice by going to Apps, then find Bixby voice. Then Disable the app. you will no longer be able to use use Bixby, but i don't use it any ways, so not problem for me as long as the battery lasts longer.
