The Pixel XL earns a 7 out of 10 on our repairability scale (10 is the easiest to repair):

Many components are modular and can easily be replaced once the display assembly is removed.

The battery has a removal tab and is adhered by a modest amount of adhesive, making its removal painless.

All of the screws are T5 Torx screws.

The opening procedure requires prying up a thin, poorly-supported display assembly making it difficult to open the phone without damage.

In addition to screws, the midframe is secured by snug, press-fit notches that make its removal (and subsequent repairs) laborious.
