The Samsung Galaxy Notes 20 both earn a 3 out of 10 on our repairability scale (10 is easiest to repair):

You'll only need one screwdriver, a standard Phillips.

Many components are modular and can be replaced independently, including the charge port.

Battery replacement remains far too difficult for a consumable component.

Screen repairs are tedious, poorly prioritized, and unnecessarily expensive.

All repairs demand battling through tough adhesive, then painstakingly cleaning and replacing it.
