Modder replaces Nintendo Switch 2 battery - $40 upgrade extends battery life by a whopping 50%

Needless to say, this isn't for the faint-hearted, but if you're confident enough of your technical knowhow in terms of tinkering around inside the handheld, it's certainly possible to replace the battery with a beefier power pack.

As Tom's Hardware highlighted, this was proved by a YouTuber who goes by the name Naga, and you can watch how the transplant is done in the above clip.

The process involves opening the Switch 2 (shockingly), disconnecting the battery (hopefully not shockingly), dissolving the glue holding the battery in (with isopropyl alcohol), removing the remaining adhesive gunk, and then inserting the replacement.

As the new battery is a touch bigger, the metal frame of the enclosure needs to be modified, cutting off the bottom section so the replacement will fit - you don't get to see that happening. There's some additional complexity around refitting the metal shield, too.

The new battery used here is an 8,000mAh effort and Naga tells us how much longer they can play Cyberpunk 2077 for - namely an extra hour. Indeed, the longevity of the Switch 2 running the sci-fi RPG went from 2 hours 18 minutes to 3 hours 25 minutes, which is an increase of almost 50%. Impressive.

Seemingly there's no difference in the weight, or nothing that you'd notice - the switched battery only weighs a few grams more, we're told.
