Nokia 101 - SIM Card Management for Calls and Messages; Dual SIM Settings Access; Setting Default SIM Cards; Choosing SIM for Each Action

Batteries last longer and perform better if allowed to
discharge fully at least once a week. You can do this by
leaving the phone switched on overnight, or until the
message RECHARGE BATTERY is displayed and the
phone shuts itself off.
NOTE: If the battery is too hot or cold, charging will be
interrupted until the battery reaches a normal
temperature.
