Nintendo 3DS XL 2015 Repairability Score: 5 out of 10 (10 is easiest to repair)

The battery is fairly easily swappable by unscrewing two screws and removing the back cover.

Screws and plastic clips are the primary fasteners, rather than adhesive. Also, no Proprietary screw types are used—only Phillips and JIS.

The top display's cables are routed in such a way that it makes them quite frustrating to remove without ripping them off, and just as difficult to re-seat properly during device reassembly.

There are tons of little components inside the 3DS, which may potentially cause problems if you happen to lose one while performing a repair.

The majority of connectors are ZIF, and it's difficult to ensure each one is connected properly without reassembling the whole thing and starting up the device.

The headphone jack and charging connector are soldered to the motherboard, meaning you need to take out your soldering iron if you accidentally break them.
