About battery aging

Batteries are a consumable item whose remaining life decreases with age. If you notice that you need to charge your battery more often than usual after a long period of use and that your usage time is noticeably shorter, have your battery checked by your local service center to see if it is time for a replacement as batteries lose life not only with use but also due to storage and environmental conditions.

Symptoms of battery aging

As your battery ages with use, you may notice a rapid decrease in battery capacity or power loss, even if the screen shows a high battery level. This is a feature of battery chemistry and is common in lithium-ion batteries.

If you are experiencing difficulty using your product due to the battery aging over time, please have your battery checked by a service center for assistance with a replacement.
