iFixit has a dedicated 5G screen guide and a battery-with-frame option. Both battery routes require removing the fragile display.
What to check before buying
Display access
The 5G-specific screen guide warns that the sensitive panel can be damaged during removal. It is the access route for deeper repairs, so a clean-looking used screen does not remove that labour risk.
Battery choices
The 5G guides cover a loose battery and a battery-plus-frame assembly. The latter has the cell already installed in the frame, but still requires screen removal and the correct 5G part.
