Important Information About the Battery
If the battery has not been used for a long period of time, you may not be able to power on
your mobile phone immediately after you begin charging the battery. Allow the battery to
charge for a few minutes with the phone powered off before attempting to power on the
phone. The on-screen charge animation may not be displayed during this period.
Over time, the battery will not hold a charge for as long as it did when it was new. When the
battery life becomes noticeably shorter than usual after being charged properly, replace the
battery with a new one of the same type.
Using data services increases demand on the battery and will reduce the length of time it can
hold a charge.
The time required to charge the battery depends on the environmental temperature and the
age of the battery.
When the battery power level is low, the phone plays an alert and displays a prompt. When the
battery power is almost exhausted, your phone will power off automatically.

distance of 1.5 cm from your body. Ensure that the device accessories such as a device case
and a device holster are not composed of metal components. Keep your device 1.5 cm away
from your body to meet the requirement earlier mentioned.
On a stormy day with thunder, do not use your device when it is being charged, to prevent any
danger caused by lightning.
When you are on a call, do not touch the antenna. Touching the antenna affects the call quality
and results in increase in power consumption. As a result, the talk time and the standby time
are reduced.
While using the device, observe the local laws and regulations, and respect others’ privacy and
legal rights.
Keep the ambient temperature between 0°C and 40°C while the device is being charged. Keep
the ambient temperature between –10°C to 55°C for using the device powered by a battery.
Prevention of Hearing Damage
Using a headset at high volume can damage your hearing. To reduce the risk of damage to
hearing, lower the headset volume to a safe and comfortable level.
Safety of Children
Comply with all precautions with regard to children’s safety. Letting a child play with your
device or its accessories, which may include parts that can be detached from the device, may
be dangerous, as it may present a choking hazard. Ensure that small children are kept away
from the device and accessories.
Accessories
Choose only batteries, chargers, and accessories approved for use with this model by the
device manufacturer. The use of any other type of battery, charger, or accessory may invalidate
any warranty for the device, may be in violation of local rules or laws, and may be dangerous.
Please contact your dealer for information about the availability of approved batteries,
chargers, and accessories in your area.
Battery and Charger
Unplug the charger from the electrical plug and the device when not in use.
The battery can be charged and discharged hundreds of times before it eventually wears out.
When the standby time and the talk time are shorter than the normal time, replace the battery.

Do not connect two poles of the battery with conductors, such as metal materials, keys, or
jewelries. Otherwise, the battery may be short-circuited and may cause injuries and burns on
your body.
If battery electrolyte leaks out, ensure that the electrolyte does not touch your skin and eyes.
When the electrolyte touches your skin or splashes into your eyes, wash your eyes with clean
water immediately and consult a doctor.
