Nintendo Switch Battery Replacement

Using the Y1 Screwdriver, remove the four tri-point screws on the back of the device, in the corners; then a single screw on top, and two screws on either side of the charging port.

Be sure to lift up the kickstand and remove this sneaky little screw around the SD card slot, and then the center screws on both sides of the device, where the Joycon brackets are screwed in place.

With the myriad of screws removed, you should now be able to pop the back cover off with minimal prying; you might need an iSesamo style spudger to get it started , just make sure you're careful around the fan exhaust, (marked in the photo) there's some tiny clips that you wouldn't want to pull off with too much force.

Remove the circled screws on the back of the metal plate, as indicated by the photos, but don't attempt to pull it off yet.

Take out the center screw, near the blower fan, and the screw in the small SD card reader assembly. Then using tweezers or a spudger, carefully remove the SD card reader and detach the flex cable from the board; you can do this by carefully sliding a spudger under the area covered by the foam and gently prying up. it comes off fairly easily.

You can now gently pull the metal plate off and set it aside, revealing the tightly designed internals of the switch, along with your battery.

To remove the battery, take some tweezers or a spudger and carefully pop the connector off vertically; it looks like it might come out perpendicular to the board, but it comes straight off with some gentle prying from underneath.

Now finally, use the long flat tipped spudger and use it to carefully separate the battery's adhesive by going in at a low angle in several different directions, I found that going in towards one side, then the other, then down the middle worked well. don't stick it underneath and pry upwards, just separate the adhesive and it comes right out.
