You’re sitting on a train, or maybe just hiding in the bathroom to escape a long family dinner, and you want to play Halo Infinite. Not a mobile version. Not a cloud-streamed mess with input lag that makes you want to throw your phone. The real deal. For a long time, that was a pipedream unless you lugged a ten-pound gaming laptop around. Then the ROG Ally Xbox handheld experience happened. Honestly, it changed the math for a lot of us who grew up tied to a plastic box under the TV.
It isn't a "mini Xbox" in the literal sense—Microsoft didn't build the hardware—but the partnership between ASUS and the Xbox team made it the closest thing we have to a portable Series S. It runs Windows 11. That's both its greatest strength and its most annoying quirk.
If you've spent any time looking at these devices, you know the market is getting crowded. You have the Steam Deck, the Lenovo Legion Go, and a dozen Chinese handhelds from brands like Ayaneo. But the ROG Ally hit a sweet spot. It brought 1080p gaming to a form factor that doesn't feel like a brick.
The Windows 11 Reality Check
Let’s get the elephant out of the room. This is a PC.
When you boot it up, you aren't greeted by a polished, locked-down console interface. You see a desktop. ASUS tries to hide this with their Armoury Crate SE software, which acts as a launcher, but eventually, you’ll have to deal with a Windows update or a pop-up that doesn't like the controller input. It’s the price you pay for freedom. Because it's Windows, the ROG Ally Xbox handheld ecosystem is massive. You get the actual Xbox App. You get Game Pass natively. No workarounds needed.
I’ve seen people complain that the Steam Deck is better because SteamOS is "cleaner." They aren't wrong. But try playing Call of Duty or Destiny 2 on a Steam Deck without installing Windows yourself. You can't. The anti-cheat software kicks you out. On the Ally, you just download the game and play. It works. Most of the time.
The Ryzen Z1 Extreme chip inside this thing is a monster. When you plug it into a 65W charger, it enters "Turbo Mode," and suddenly you’re hitting frame rates that would have been impossible on a portable three years ago. It’s wild. You’re playing Cyberpunk 2077 at 40-50 FPS on a screen that fits in your hands.
Screen Quality and Why It Matters
Most people focus on the GPU. They forget the screen.
The Ally features a 7-inch, 120Hz 1080p touchscreen. But the secret sauce isn't the resolution—it's Variable Refresh Rate (VRR). If you’re a nerd about screen tearing, this is the Holy Grail. Most handhelds have a fixed refresh rate. If your game drops from 60 FPS to 45 FPS, it looks stuttery and gross. VRR synchronizes the screen to the game's actual output.
Everything feels smooth. Even when the hardware is struggling to keep up with a heavy game, your eyes don't feel the "jank" as much. It’s one of those things you don't realize you need until you go back to a device that doesn't have it. Then you notice every single dropped frame.
Battery Life: The Brutal Truth
We have to be honest here. The battery is... not great.
If you’re playing a demanding AAA title like Starfield at 25W or 30W, you might get an hour. Maybe ninety minutes if you dim the screen and pray. It sucks. There is no other way to put it. If you’re buying this for a 10-hour flight across the Atlantic, buy a massive power bank too.
On the flip side, if you're playing indie titles—think Hades or Dead Cells—you can drop the wattage way down to 10W or even 7W. In those cases, you can squeeze out four or five hours. But let’s be real, nobody buys a Z1 Extreme device just to play 2D platformers. You want the power. And power stays hungry.
Ergonomics and Living with the Buttons
ASUS went with an offset stick layout, exactly like an Xbox controller. It feels familiar. The triggers have a good throw to them, and the macro buttons on the back are tactile enough to be useful without being in the way.
The weight is the surprising part. It’s roughly 608 grams. For comparison, the Steam Deck is about 669 grams. It doesn't sound like much of a difference, but over an hour of gaming, your wrists will tell you otherwise. The Ally feels "light" in a way that makes it feel slightly more premium, though the white plastic does pick up dirt like a magnet. Keep some wipes nearby.

One legitimate concern: the SD card slot.
Early units had a nasty habit of "cooking" SD cards because the slot was placed too close to the exhaust vent. ASUS has since updated the fan curves to keep things cooler, and newer hardware revisions supposedly fixed the thermal pathing. But if you're buying a used unit, be careful. Most long-term users have just swapped the internal M.2 2230 SSD for a 2TB drive and called it a day. It’s a relatively easy surgery if you have a screwdriver and ten minutes.
The Xbox Game Pass Synergy
This is the "killer app" for the device.
Microsoft has been pushing the "Xbox everywhere" narrative for years. With the ROG Ally, it finally feels true. When you buy the console, it usually comes with a few months of Game Pass Ultimate. You sign in, and your cloud saves from your Series X just... appear. You were playing Forza on the couch? Pick up the Ally, and you're at the exact same race, same car, same spot.
It makes the Xbox ecosystem feel cohesive. You aren't "re-buying" your library like you might have to if you switched from console to a Steam-only handheld. If you already have a library of "Play Anywhere" titles, they are just there.
Dealing with the Quirks
It isn't all sunshine. You will encounter bugs.

Sometimes the "Command Center" (the little button that lets you change brightness or resolution mid-game) won't pop up. Sometimes a game will launch in windowed mode for no reason. This is the "PC Tax." You have to be willing to tinker. If you want a device that works 100% of the time with zero input from you, buy a Nintendo Switch. If you want a device that can do anything—including docking to a monitor and acting as a full desktop computer—the Ally is the play.
I’ve actually used mine to edit a short video and write an email. It’s awkward on a 7-inch screen, but the fact that you can do it is pretty cool.
Practical Steps for New Owners
If you just picked one up or are about to hit the "buy" button, don't just jump into a game immediately. You'll have a bad time.
- Update everything. Run Windows Update, then go into the MyASUS app and update the BIOS, then go into Armoury Crate and update the firmware. It's a lot. Do it anyway.
- Disable "Enhanced Core" features. There are plenty of guides online showing how to disable certain Windows virtualization features that hog CPU cycles. Doing this can give you a 5-10% boost in some games.
- Get a 65W+ Power Bank. Look for one that supports Power Delivery (PD) 3.0. This ensures you can play in Turbo Mode even when you aren't near a wall outlet.
- Set up your TDP profiles. Don't just stay in "Performance" mode. Create a custom 18W profile. It’s often the "sweet spot" where you get great performance without the fans sounding like a jet engine.
- Check the Deadzones. Some users report the sticks feel "loose" out of the box. You can calibrate the deadzones in Armoury Crate to make them feel tighter.
The ROG Ally is a weird, powerful, flawed, and brilliant piece of tech. It’s the first time the "Xbox in your pocket" dream has felt like a high-end reality rather than a compromised experiment. Just keep your charger handy.
