BATTERY INFORMATION CHARGING THE BATTERY The battery delivered with your smartphone is not fully charged. We recommend that you charge the battery for 4 hours before you use the phone for the first time. If you are charging a new battery, or a battery that has run out completely, it may take a while before you get any indication (the top indicator lights up and the battery meter appears in the display) that the battery is being charged. Please note that you cannot turn on the phone before the indicator lights up and the battery meter appears in the display. The battery can only be charged in temperatures between +5°C (+41°F) and +45°C (+113°F). 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 time could have reduced capacity the first few times it is used. The amount of battery power indicated by your battery icon is an estimate that may vary depending on your charging and use patterns. To ensure adequate power supply, keep your battery fully charged or carry additional charged batteries. Use only Ericsson original batteries and chargers. Using other batteries and chargers could be dangerous, and the warranty does not cover product failures which have been caused by use of nonEricsson original batteries and chargers. • Do not expose the battery to extreme temperatures, never above +60°C (+140°F). For maximum battery capacity, use the battery in room temperature. If the battery is used in cold temperatures, the battery capacity will be reduced. • Turn off your smartphone before removing the battery. • Use the battery for the intended purpose only. • Do not attempt to take the battery apart. • Do not let the metal contacts on the battery touch another metal object. This could short-circuit and damage the battery. 238 Important Information
