BATTERY INFORMATION
New Batteries
The battery delivered with your smartphone is not fully charged. We
recommend that you fully charge it before you use it for the first time.
Battery Use and Care
A rechargeable battery has a long service life if treated properly. A
new battery, or one that has not been used for a long period of time
could have reduced capacity the first few times it is being used.
The talk and standby times depend on the actual transmission
conditions when using the smartphone. If the smartphone is used
close to a base station, less power is required and talk and standby
times are prolonged. Use only Ericsson original batteries and
chargers. Using non original Ericsson accessories could be dangerous
and the warranty does not cover product failures which have been
caused by use of non-Ericsson original accessories.
Do not expose your battery to extreme temperatures, never above
+60°C (+140°F). If the battery is used in cold temperatures the
battery capacity will be reduced.
The battery can only be charged when the temperature is between
+5°C (+41°F) and +45°C (+113°F).
Turn off your smartphone before removing the battery.
Use only the battery for the intended purpose.
Do not attempt to take a battery apart.
Do not let the metal contacts on the battery touch another metal
object. This could short-circuit and damage the battery.
Do not expose a battery to open flames. This could cause the
battery to explode.
Do not expose a battery to liquid.
Do not mutilate, puncture or dispose of batteries in fire. The
batteries can burst or explode, releasing hazardous chemicals.
If a battery should accidentally leak, do not allow the contents to
come into contact with your skin or your eyes.
