Nintendo rolled out a nice surprise for Switch 2 owners earlier this week. It’s called Handheld Boost Mode, and it runs Switch 1 games as if they were docked, even while in handheld mode. Sounds straightforward enough, but the results are really impressive. Players have also discovered that it really kills battery life, too, but so far the trade-off feels worth it.
One Switch 2 owner tested how much extra power handheld boost mode uses, and it’s a shocking amount. Reddit user JampyL ran the Switch port of Doom Eternal in handheld boost mode for a Switch 2, starting at full charge, to see how long it would take to deplete the battery life relative to having the feature turned off. They got just over five hours in regular mode, but only three hours and 43 minutes in boost mode.
That’s a whopping 23 percent drop in battery life. Other games might even perform worse, which could become an issue since this is specifically for when players are using the Switch 2 in handheld mode. At the same time, most are happy with the trade-off. Unless you’re traveling, that’s still more than enough juice to play in between charges. It’s also on par with the type of battery life players have come to expect from regular Switch 2 games running on the more powerful hardware.
And the results are definitely worth it. Lots of Switch 1 games, especially those released near the end of its life cycle, were compromised in general, but especially rough in handheld mode. The most infamous example was Xenoblade Chronicles 2, which fans have joked looked at times like a Vita game when not docked. Resolution and various rendering techniques were all impacted by the power constraints of the older hardware when it was portable.
everyone needs to turn Handheld Boost ON right now.
It’s not quite Switch 2 Edition / compatibility update level, but in handheld it basically runs at docked quality and the difference is obvious. Feels SO much better!
it will eat up your battery like ass though https://t.co/9U1rbEpIuH pic.twitter.com/0eXDJUgvDq

Boost mode on Switch 2 undoes all of those issues. Comparisons for games like Astral Chain and Minecraft all show clear improvements, especially when it comes to things like anti-aliasing (getting rid of all the jagged lines). Some of the best Switch 1 games just look way more crisp and clear in handheld boost mode on Switch 2 when not docked. Even rough ports like The Witcher 3 and The Outer Worlds look noticeably less bad.
The new feature is arguably one of the best things to get added to Switch 2 since launch and makes it even more appealing to revisit the platform’s last-gen library on the new hardware. For that exact reason, it’s kind of wild that Nintendo just shadow-dropped it out of nowhere without any fanfare. I hope they have some other cool hardware updates waiting in the wings as well as we approach the device’s one-year anniversary.
