Hi @ayo52202
Even rechargeable batteries have a lifespan.
Try replacing the battery and check if that resolves the problem.
Here's a teardown [https://www.youtube.com/watch?v=03ekj09FiJg|video] that may help. The battery can be seen being removed at 8:31 minutes into the video.
Search online for ''HE354 battery'' or ''BPAOP00001B'' (this is the Nokia part number for the battery) to find suppliers that suit you best.
