You must use the charger and USB cable that came with your device for quicker charging
speeds. Using other chargers or USB cables may cause your device to continuously restart
or increase the charging time. It may also cause the charger to overheat, or even damage
your device.
l If your device does not respond when you press the power button, the battery is probably
empty
. Charge your battery for at least 10 minutes (use the charger that came with your
device), and then restart your device.
l Your device automatically conducts a safety check when you connect it to a charger or
other devices. If your device detects that the USB port is wet, it will automatically stop
charging and display a safety message. If this message is displayed, unplug the USB
cable from your device and allow the USB port to dry out completely to avoid damaging
your device or battery.
Using a USB port to charge your device
If you do not have access to a charger, you can charge your device by connecting it to a
computer with a USB cable.

access to device data? will be displayed in a popup dialog.
2 Touch No, charge only.
If another USB connection mode has been selected, swipe down from the status bar to open the
notification panel. Touch File transfer via USB, and then select Charge only.
Using your USB Type-C port to charge other devices
USB Type-C connectors are reversible and can be inserted either way up. It is possible to use
your device to charge another device with a USB Type-C cable.
1 Use a USB Type-C cable to connect your device to the other device.
2 On your device, swipe down from the status bar to open the notification panel, and then set
the USB connection mode to Reverse charging.
3 On the other device, set the USB connection mode to Charge only.
To use another device to charge your device, set the USB connection mode to Charge only on
your device, and then set the USB connection mode on the other device to Reverse charging.
Safety information
l Only use genuine Huawei batteries, chargers, and USB cables to charge your device. Third-
party accessories are a potential safety hazard and may impair your device's performance.

notice a significant deterioration in your device's battery life, purchase a genuine Huawei
replacement battery. Do not attempt to remove built-in batteries. If your device has a built-in
battery, contact an authorized Huawei service center for a replacement. If the battery is
removable, replace it with a genuine Huawei battery.
