Sustained brightness is 600 nits, 1000 nits is peak brightness for HDR content. Still an improvement of course.
I’m wondering whether the charging circuitry is largely the same except for the quicker charging to 80 %. I’d love to be able to use some higher-powered USB-C hubs with PD passthrough, where currently a hub using 15 watts leaves 30 watts for the deck, and using a higher wattage charger won’t change that because the Deck only requests 45 watts (15 V @ 3 A). Would be great if the new Deck could do, say, 60 watts (20 V @ 3 A), because leaving just 30 watts to the Deck is right on the edge under full load with an external display, meaning it has to fallback to battery momentarily, which isn’t great.
Another nice thing to have would be a low-power standby/download mode, for which they’d probably have to tweak the hardware a bit. I don’t use my Deck too often (great device, but it only fills specific gaps in my gaming needs), and every time I pick it up it starts downloading quite a few game updates.
The OLED model is tempting, but I don’t use the Deck enough to justify upgrading I think.
A bit sad for these guys who made a display upgrade for the original Deck released a few weeks ago (the 1920x1200 one), as most people who really care about display quality will probably just upgrade to the OLED model instead. The higher resolution seems rather pointless (the Deck doesn’t have enough oompfh to run modern games in this resolution), especially compared to a bigger, brighter, higher refresh rate OLED screen.
