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
