12. Phone and Battery Care
- Keep in mind that a new battery’ s full performance is achieved only after two or three times
of complete charging and discharging cycles!
- The battery can be charged and discharged hundreds of times but it will eventually wear out.
When the operating time (talk-time and stand-by time) is noticeably shorter than normal, The
symptom means the time to buy a new battery.
- Do not attempt to open the casing on your phone or its battery.
- Always keep SIM card out of children’ s reach.
- Use your phone battery only for its intended purpose, and never use any charger or battery
which is damaged or worn out.
- Never allow the battery terminals to short circuit, as this can cause damage to the battery or
connecting object. (a short circuit can occur if a metallic object such as a coin, clip or pen
causes direct connection between the + and – terminals of the battery)
Therefore, always take adequate precautions when carrying a spare battery in a purse or
pocket.
- Battery must be recycled or disposed properly, and must not be disposed of in municipal
waste. Never dispose batteries in a fire.
- When you unplug your phone from its charger, grasp and pull the plug, not the power cord.
- For good operation times, discharge a Li-ion battery from time to time by leaving your phone
switched on until it turns itself off.
- Do not drop, knock or shake it.
- Do not use harsh chemicals, cleaning solvents, or strong detergents to clean it. Wipe it with a
soft cloth slightly dampened in a mild soap-and-water solution.
