Wait, really? How does that work? I thought they didn't really upgrade the specs much? https://www.digitaltrends.com/computing/steam-deck-oled-vs-s...
These benchmarks show a few FPS difference (maybe 10% at most), nowhere near 3-4 times faster?
edit: did you mean 3-4x as long? But that's also hard to believe... a 3-4x improvement in battery life for any device would be a HUGE upgrade that normally takes like a decade to achieve, not a year or two?
