What about Android smartphones that do not have an emergency power saving function?
For Android smartphones that do not have an emergency power saving function, manually lowering the screen brightness, turning off Wi-Fi and Bluetooth, turning off data communication when not needed, etc. will save battery power.

When I try to enable the low power mode (photo = left), a warning is displayed (right) When the low power mode is set, the battery icon turns yellow and the percentage display is forcibly turned on.
