Summary
The Samsung Galaxy S21 Ultra offers moderate repairability. While the battery and its cable are easily accessible and aided by pull tabs for removal the use of adhesives on both the back cover and the battery makes disassembly more challenging. The screen can be replaced without having to remove many internal components which is a positive for repair ease. However gaining access to some cables requires the removal of plastic covers over the boards adding extra steps to the process. Overall the design balances accessibility with a few adhesive-related complications.
