Lumia 650 battery

Thank you for the information. Since there is no pending update on your phone and based on the other info you've provided, this seems to be a hardware issue.

You can also contact our B2X team for in-depth support through this link. Click the Radio button for Enter IMEI number > Enter the IMEI number > Get started. You'll be in good hands with them.
