    Battery charging tips and precautions
    •	When the battery power is low, the battery icon appears empty.
    •	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.
    •	While charging, the device and the charger may heat up. This is normal and should not 
    affect the device’s lifespan or performance. If the battery gets hotter than usual, the 
    charger may stop charging.
    •	If you charge the device while the multipurpose jack is wet, the device may be damaged. 
    Thoroughly dry the multipurpose jack before charging the device.
    •	If the device is not charging properly, take the device and the charger to a Samsung 
    Service Centre.

    Fast charging
    The device has a built-in fast charging feature. You can use this feature to charge the battery 
    more quickly while the device or its screen is turned off.
    About Fast charging
    •	Fast charging uses battery charging technology that charges the battery faster by 
    increasing the charging power. The device supports Samsung’s Adaptive fast charging 
    feature and Qualcomm Quick Charge 2.0.
    •	To use Fast charging on your device, connect it to a battery charger that supports 
    Adaptive fast charging or Quick Charge 2.0.
    Increasing the charging speed
    To increase the charging speed, turn the device or its screen off when you charge the battery.
    •	While charging the battery when the device is turned off, the  icon appears on the 
    screen.
    •	You cannot use the fast charging feature when the screen is turned on. Turn off the 
    screen to increase the charging speed.
    If the fast charging feature is not activated, on the Home screen, tap 
    Apps → Settings → 
    Battery, and then tap the Fast cable charging switch to activate it.
    •	You cannot use the built-in fast charging feature when you charge the battery 
    using a standard battery charger.
    •	If the device heats up or the ambient air temperature rises, the charging speed may 
    decrease automatically. This is a normal operating condition to prevent damage to 
    the device.

    Wireless charging
    The device has a built-in wireless charging coil. You can charge the battery using a wireless 
    charger (sold separately).
    Fast wireless charging
    You can charge your device faster using the fast wireless charging feature. To use this feature, 
    you must use a charger and components that support the fast wireless charging feature.
    A fan inside the charger may produce noise during fast wireless charging. To reduce 
    the fan noise, you must deactivate the fast wireless charging feature. The on/off 
    option will be added in your device’s settings menu when you first place it on the 
    charger. On the Home screen, tap 
    Apps → Settings → Battery, and then tap the Fast 
    wireless charging
     switch to deactivate it. Deactivating this feature will reduce noise, 
    but may result in slower charging times.
    Charging the battery
    1 Place the centre of the device’s back on the centre of the wireless charger.
    You can check the remaining charging time on the screen. The actual remaining time 
    may vary depending on the charging conditions.

    2 After fully charging, disconnect the device from the wireless charger.
    •	When there are foreign materials between the device and the wireless charger, the 
    device may not charge properly.
    •	If you use the wireless charger in areas with weak network signals, you may lose 
    network reception.
    •	Use Samsung-approved wireless chargers. If you use other wireless chargers, the 
    battery may not charge properly.
    Power saving mode
    Save the battery power by limiting the device’s functions.
    On the Home screen, tap 
    Apps → Settings → Battery → Power saving mode, and then tap 
    the switch to activate it.
    To automatically activate power saving mode when the remaining battery power reaches the 
    preset level, tap 
    Start power saving and select an option.
    Ultra power saving mode
    Use this mode to extend the device’s battery power. In ultra power saving mode, the device 
    performs the following:
    •	Displays colours on the screen as grey tones.
    •	Restricts the available apps to essential and selected apps only.
    •	Deactivates the mobile data connection when the screen turns off.
    •	Deactivates the  Wi-Fi and Bluetooth features.
    On the Home screen, tap 
    Apps → Settings → Battery → Ultra power saving mode, and 
    then tap the switch to activate it.
    To deactivate ultra power saving mode, tap 
    MORE → Disable Ultra power saving mode.
    The usage time left shows the time remaining before the battery power runs 
    out. Usage time left may vary depending on your device settings and operating 
    conditions.
