Because some app services running in background so I recommend you to do below things before charging the smartphone: 1) Turn on battery Saver mode 2) set background process limit to none from developer section in Settings 3) Put heavy apps in deep sleep mode manually... You need to turn of all things that's running in the background... and bonus tip remove smartphone's back cover before charging, this heats up battery more. Heat is villain for battery. That's it. This tips is working for me. I hope it's working for you also...
