When to Charge the Battery
When the battery is low and only a few minutes of
operation remain, the device sounds a warning tone
at regular intervals. In this condition, your device
conserves its remaining battery power by dimming the
screen. When the battery level becomes too low, the
device automatically turns off.
For a quick check of your battery level:
► View the battery charge indicator located in the top
right corner of your device’s display. A solid color
( ) indicates a full charge.
While charging, the device and the charger may
become hot when using wireless charging or fast
charging. This does not affect the device’s lifespan or
performance and is in the device’s normal range of
operation.
The charger may stop charging if the battery becomes
too hot.
