3.Getting started
3.1 Installing the SIM Card and the Battery
A SIM card carries useful information, including your mobile phone number, PIN (Personal
Identification Number),PUK (PIN Unlocking Key),IMSI (International Mobile Subscriber Identity), network
information, contacts data, and short messages data.
Note:
After powering off your mobile phone, wait for a few seconds before removing or inserting a SIM card.
Exercise caution when operating a SIM card, as friction or bending will damage the SIM card.
Properly keep the mobile phone and its fittings such as the SIM cards beyond children's reach.
Note:
The SD card is a miniature object and max expand to 128GB. Keep it out of the reach of children for fear
that children swallow it!
3.2 Charging the Battery
The lithium battery delivered with the mobile phone can be put into use immediately after being
unpacked. A new battery will have maximum performance after the first three full charge/discharge cycles.
Battery level indication:
Your mobile phone can monitor and display the battery state.
Normally the remaining energy of the battery is indicated by the battery level icon at the upper right
corner of the display screen.
When the battery energy is insufficient, the mobile phone prompts "Battery may run out soon".
Using a travel adapter:
Install the battery into the mobile phone before charging the battery.
Connect the adapter of the travel charger with the charging slot in the mobile phone. Ensure that the
adapter is fully inserted.
Insert the plug of the travel charger to an appropriate power outlet.
During the charging, the battery level grids in the battery icon keep flickering till the battery is fully
charged.
The battery icon does no longer flicker when the charging process ends.
Note:
Ensure that the plug of the charger, the plug of the headphones, and the plug of the USB cable are
inserted in the right direction. Inserting them in a wrong direction may cause charging failure or other
problems.
Before the charging, ensure that the standard voltage and frequency of the local mains supply match
the rated voltage and power of the travel charger.
Optimizing battery life
You can extend your battery’s life between charges by turning off features that you don’t need. You can
also monitor how applications and system resources consume battery power.
To guarantee the optimal performance of your battery, please stick to the following rules:
Turn off radios that you aren’t using. If you aren’t using Wi-Fi, Bluetooth, use the Setting application to
turn them off.
Turn down screen brightness and set a shorter screen timeout.
If you don’t need them, turn off automatic syncing for Gmail, Calendar, Contacts, and other
applications.
