The Honor 400 shows a mixed level of repairability. While the battery is relatively easy to reach with accessible cables and the inclusion of pull tabs helps with removal adhesive is used both for the back cover and the battery which complicates repairs. Screen replacements are particularly challenging since several internal components must be disassembled first. Additionally plastic covers over the circuit boards add another step before accessing critical connections. Overall the device offers some user-friendly battery repair features but falls short in ease of full disassembly and screen replacement.
