A simple flow that, if the device is unplugged from a power source and Power Save mode is not enabled, creates a pop-up reminder message to turn it on. For convenience it will also open the Power Save settings screen. Useful for people who prefer to have Power Save active whenever the device is not plugged.
Ideally this flow would be able to turn on Power Save mode by itself, but that requires root access.
This flow is designed for devices whose Power Save mode does not trigger automatically at 100% remaining power. For example, on some devices it only triggers at max 75%, requiring manual activation for any higher value. The app "SystemUI Tuner" ( https://forum.xda-developers.com/t/app-6-0-systemui-tuner.3588675/ ) allows the user to tweak the Power Save mode up to 100% which makes this flow unnecessary. Please see SystenUI Tuner's documentation ( https://github.com/zacharee/Tweaker/blob/master/app/src/main/assets/terms.md ) to determine if your device is compatible.
