Charging the Battery
Before charging the battery, ensure that it has been properly inserted into your phone.
1. Connect the USB cable that came with your mobile phone to the charger.
Note:
Use only Cat
®
approved chargers and cables. Unapproved equipment may cause damage to the
device or cause batteries to explode.
2. Open the USB port cover. Connect the USB cable to the USB port of your phone.
Note:
Be careful not to use excessive force when plugging the USB cable.
Be aware of the correct orientation of the plug. Damage can be caused by attempting to insert the
connector the wrong way which is not covered by the warranty.
3. Insert the other end of the cable into the wall charger and insert into an electrical socket.
Note:
The touchscreen may not function correctly if the power source is not stable.
4. When charging is complete, remove the connector from the device and then remove the wall
charger.
Note:
Never remove the battery during charging as doing so may cause damage to the device.
Note:
If the battery is completely discharged, it will not be possible to switch on the device when the power
is first connected. Allow an exhausted battery to charge for a few minutes before attempting to
switch on the device.
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 message. When
the battery power is almost exhausted, your phone will power off automatically.
