2.7Important Information About the Battery

•If the battery has not been used for a long 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 the phone on.

•As it ages, thebattery’sperformance will degrade, in particular it will not hold charge 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 the power consumption of the phone and will therefore reduce the length of time that the phone can be used between battery charges.

•The time required to fully charge the battery depends on the ambient temperature and the age of the battery.

•When the battery power is low, the phone will alert you and display a message. When the battery power is almost exhausted, your phone will power off automatically.
