Nintendo says 2 to 6.5 hours. In reality, expect something in between depending on how you play.
That 7.9-inch 1080p screen at 120Hz is gorgeous, but it drinks power. Running a graphically intense game like Mario Kart World with brightness cranked? You're looking at closer to 2 hours, maybe 2.5.
Playing a chill indie game or an older backward-compatible title with moderate brightness? 5-6 hours is realistic.
The console pulls about 10 watts during demanding portable gameplay. Screen brightness is the easiest lever to pull if you need more time.
Here's the thing. The Switch 2 supports 60W charging, but it only actually uses 15-17W. Nintendo built in this limitation to keep the battery healthy long-term. Less heat, longer lifespan.
Full charge from dead takes about 3 hours with the console off. You can play while charging, but the console gets warm.
If you mostly play docked, go into System Settings and turn on "Stop charging at 90%." It's off by default. Keeping the battery at 90% instead of 100% helps preserve its capacity over years of use.
For a long flight or road trip, bring a USB-C charger. For a few hours of gaming? The battery handles it just fine.
