14.26 How long should I charge the battery for the first
time?
Charge the battery until it's full.
14.27 What are the precautions when I charge my phone
for the first time?
Use the battery and charger that come with your phone.
Charge the battery from time to time, which can increase its lifespan. Do not wait until
the battery level becomes low.
When the battery is fully charged, disconnect it from the charger. Otherwise, the battery
and charger may be damaged.
14.28 How long does it take to fully charge my phone?
The battery capacity varies by phone model, resulting in different charging time.
The indicator on your phone tells you its battery level. It turns green when the battery
level is higher than 90%. You can also check the screen for charging status.
14.29 Why can't I charge my phone after I connect it to a
computer?
The computer's USB port may have insufficient power supply.
If your phone is connected to a desktop computer, connect the data cable to the USB port
on the rear side of the computer host.
If your phone is connected to a laptop computer, directly use the USB port on the laptop
computer. If you are using an external USB port, power supply may be insufficient.
If the problem persists, use the charger to charge your phone instead.
14.30 Can I use a Huawei charger in other countries?
Huawei chargers have certain requirements for the input voltage, generally 100–240 V and
50–60 Hz. For details, see the instructions on the charger label. If the voltage in the country or
region you are currently in is within that range, you can use the charger without a transformer.
The power plug shape may be different in other countries, so a power adapter may be
required.
