The Huawei Mate30 Pro earns a 5 out of 10 on our repairability scale (10 is the easiest to repair):

Almost every component is modular and can be replaced independently.

Only standard Phillips screws are used.

Pull tabs make fairly quick work of battery replacement, once you've carved through the rear cover, plastic frame, and some cables.

A few components require extended disassembly for service.

The display can be removed without removing the battery, although it's still tough to pry off and impeded by some cables.

Glued-down front and back glass means greater risk of breakage, while making all repairs more difficult and lengthy.
