Nexus 5 teardown shows 8/10 score in the repairability test

First of all the Nexus 5 is sealed in a uni-body design despite that it got a score of 8/10. The internal components are not tough to replace. You can replace the 2300 mAh battery. The back has wireless charging coils as well as the NFC connectivity. But the worst part is that the whole screen assembly is somehow glued together, it won't be easy to replace nor cheap. So we advice you to put a protector on screen and avoid dropping the Nexus 5.
