Estimating the standby time of your device
Standby time refers to the amount of time the battery can last when your device is
connected to the network but is not in active use, for example, to receive or make
phone calls. STAMINA mode, when activated, continuously evaluates the remaining
standby time, which can vary depending on how you use your device. STAMINA
mode is more effective in lengthening the standby time if you keep the screen of your
device locked. If you rarely lock the screen, you may not see much improvement in
battery performance.
When you use your device for the first time, the estimated standby time may not be accurate
since there is no previous usage history to estimate from.

Using Low battery mode
You can activate the Low battery mode feature to save power when the battery level

and the vibrate function so that you can reduce battery consumption.
