The OnePlus 6 earns a 5 out of 10 on our repairability scale (10 is the easiest to repair):

The battery can be accessed almost the moment you open the phone, and is only lightly adhered in place. Plus, there's a convenient pull tab.

Many components are modular and can be individually replaced.

All the threaded fasteners are of the standard Phillips variety.

Display replacement, the most common repair, is not prioritized in the design and will take a lot of work.

Front and back glass means twice the risk of cracks—without even the benefit of wireless charging.

The primary access point for all repairs is heavily glued in place.
