Your phone is powered by a rechargeable battery.
The battery can be charged and discharged hundreds of times but it will eventually wear out. When the operating time (talk-time and standby time) is noticeably shorter than normal, it is time to buy a new battery.
- Use only batteries approved by the phone manufacturer and recharge your battery only with the chargers approved by the manufacturer.
- Unplug the charger when not in use.
- Do not leave the battery connected to a charger for longer than a week, since overcharging may shorten its lifetime.
- If left unused, a fully charged battery will discharge itself over time.
- Temperature extremes can affect the ability of your battery to charge.
- Use the battery only for its intended purpose.
- Never use any charger or battery that is damaged.
- Do not short-circuit the battery. Accidental short-circuiting can occur when a metallic object (coin, clip or pen) causes direct connection of the + and - terminals of the battery (metal strips on the battery), for example when you carry a spare battery in your pocket or purse. Short-circuiting the terminals may damage the battery or the connecting object.
- Leaving the battery in hot or cold places, such as in a closed car in summer or winter conditions, will reduce the capacity and lifetime of the battery. Always try to keep the battery between 15°C and 25°C (59°F and 77°F). A phone with a hot or cold battery may temporarily not work, even when the battery is fully charged.
- Battery performance is particularly limited in temperatures well below freezing.
- Do not dispose of batteries in a fire!
- Dispose of batteries according to local regulations (e.g. recycling). Do not dispose as household waste.

A new battery's full performance is achieved only after two or three complete charge and discharge cycles.
