Limiting the charge amount [Battery Care]
Charge and discharge cycles cause the capacity of the lithium-ion battery to decrease, resulting
in shortening the battery life. You can use the [Battery Care] mode to reduce the capacity
decrement caused by charge and discharge cycles, i.e., prevent shortening the battery life.
1. From the Home menu, select
[Settings] [Common Settings] [Battery Care]
desired setting type.
Type Description
[On] Uses the [Battery Care] mode.
[Off] Uses the normal recharge mode. (Default setting)
Note
When [Battery Care] is set to [On], the maximum recharge capacity is limited to 90%. As a
result, the battery life between charges is shortened by about 10%.
In the [Battery Care] mode, the first bar of the battery indicator will disappear somewhat
quicker than normal. This is a result of stopping recharging the battery before becoming fully
charged (in order to extend the battery lifespan) and is not a malfunction.
