When To Charge The Battery - Samsung GALAXY S8 User Manual

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.
