Charge the battery.
Tips:
You can use the phone while it is charging.
Keeping the charger plugged to the mobile phone when the battery is
fully charged will not damage the battery.
If a fully charged battery left unused, it will lost its charge over time.
If a battery is being used for the first time or the battery has not been
used for a prolonged period, it may take longer time to recharge.
