Battery Charging: Different batteries have different characteristics, so users must follow the manufacturer's instructions for charging. In standby mode, the phone still consumes battery power. For quick charging, it is recommended to turn off the phone or remove the battery to charge it.
Quick Charging: Some automated smart chargers, when the indicator light changes, only indicate that the battery is 90% charged. The charger will automatically switch to slow charging to fully charge the battery. It is best for users to fully charge the battery before use to avoid shortening its lifespan.
Battery Memory Effect: If the battery is a nickel-cadmium (NiCd) type, not fully charging or discharging the battery over time can leave traces inside the battery, reducing its capacity. This phenomenon is called the battery memory effect.
Regular Memory Elimination: The method to eliminate memory is to completely discharge the battery and then fully recharge it. Discharge can be done using a discharger or a charger with a discharge function. Alternatively, you can use the phone's standby mode. To speed up the discharge, turn on the screen and the backlight of the phone buttons. Ensure the battery can fully recharge by following the time control instructions in the manual, repeating the charge and discharge process two to three times.
