Reducing the battery consumption
Your device provides various options that help you conserve battery power.
• Optimize the device using the device care feature.
• When you are not using the device, turn off the screen by pressing the Side key.
• Activate power saving mode.
• Close unnecessary apps.
• Deactivate the Bluetooth feature when not in use.
• Deactivate auto-syncing of apps that need to be synced.

Battery charging tips and precautions
• If the battery is completely discharged, the device cannot be turned on immediately
when the charger is connected. Allow a depleted battery to charge for a few minutes
before turning on the device.
• If you use multiple apps at once, network apps, or apps that need a connection to
another device, the battery will drain quickly. To avoid losing power during a data
transfer, always use these apps after fully charging the battery.
• Using a power source other than the charger, such as a computer, may result in a slower
charging speed due to a lower electric current.
• The device can be used while it is charging, but it may take longer to fully charge the
battery.
• If the device receives an unstable power supply while charging, the touchscreen may not
function. If this happens, unplug the charger from the device.
