Despite the passage of time and a number of updates, I still cannot bring myself to purchase an Xbox Ally. My reservations remain tied not only to the hardware itself but also to the customized version of Windows that powers it—a system that, in my judgment, is still far from being refined enough for widespread, mainstream use. The so-called Xbox Full Screen Experience (FSE), although an ambitious step toward optimizing Windows for handheld gaming, continues to demand substantial improvement before it reaches an acceptable level of polish. Yet, it is important to note that roughly two months have passed since I criticized both the more affordable $600 white Xbox Ally and expressed hesitation toward the higher-end $1,000 black version. Since then, one of the most persistent frustrations I’ve had with Windows on these portable devices has finally begun to show tangible signs of progress.
My evaluation of these handheld consoles certainly did not cease after publishing my initial October review. I’ve continued hands-on testing, immersing myself in titles such as *Hollow Knight: Silksong* and *Blue Prince* to assess day-to-day reliability. Extending my experimentation even further, I also installed the Xbox FSE on an MSI Claw 8 AI Plus. Following an almost countless stream of firmware patches, operating system tweaks, and game bar updates, I am beginning—cautiously—to trust two of these Windows handhelds to suspend and resume properly, preserving both my game state and the battery charge while asleep. Even the third unit, although not yet flawless, no longer exhibits the same troubling inconsistencies I once encountered.
For years, poor sleep performance has been one of the definitive reasons enthusiasts favored systems like Valve’s Steam Deck or Nintendo’s Switch over Windows-based portables. For me personally, the ease of suspending gameplay at will is the defining aspect of handheld gaming. The ability to pause and resume a demanding title at the touch of a button—playing in short bursts of five, ten, or twenty minutes—fundamentally changes how long, story-driven games fit into everyday life. It makes completion achievable for those of us who juggle tight schedules. If the hardware and software combination cannot reliably deliver that instant-stop, instant-resume experience, the essence of portable gaming is simply lost.
Historically, Windows has earned a dismal reputation regarding sleep management; systems often failed to suspend correctly, corrupted sessions, or drained power excessively. However, December marked a rare and welcome change. Using the premium black Xbox Ally X, I was able to trust it through multiple sleep cycles without losing progress even once. On one occasion, I left a game suspended for nearly nine consecutive days; upon returning, everything remained frozen precisely where I had left it. The device’s power consumption in sleep mode appears far more balanced than before—battery levels dropped only four to eight percent per day, totaling about forty percent depletion after the nine-day pause.
Of course, perfection remains elusive. I occasionally face irritations like delayed input control after resuming or malfunctioning Xbox and Asus buttons when Windows initiates background updates. At one point, after a prolonged sleep session, the operating system inexplicably demanded PIN reauthentication. The hardware has other caveats too—my colleague Tom Warren’s Ally X suffered an SSD failure. Nevertheless, that seems likely attributable to the drive manufacturer rather than Asus, as the device’s sleep performance remained consistent before the malfunction. Assuming such issues are isolated component defects, the Xbox Ally X finally feels like a product I could depend on daily.
The outlook for the base “white” Xbox Ally, equipped with AMD’s Z2 A chip, is drastically different. Across two separate units tested over several months—and despite conscientiously applying every Windows, Asus, Game Bar, and Xbox App update, many of which purported to address sleep problems—the devices repeatedly woke themselves without user input. I could literally watch them turn on spontaneously during the workday, wasting power until their batteries died. On one test conducted on November 19th, I placed a black Ally X and a white Ally side by side at similar battery levels, 96 percent and 93 percent respectively. Thirteen hours later, the white unit had drained completely while the black version still retained 91 percent. A second trial on November 20th produced a similar disparity: the white Ally depleted its power after four days while the black model still maintained 61 percent.
In an effort to diagnose the problem further, I performed a factory reset on one of the white models. Though I noticed some progress—the system sometimes preserved my session correctly—sporadic behavior persisted. On December 6th, for example, I discovered the handheld overheating in my shoulder bag. System logs revealed that it had inexplicably woken around midnight, turned off its display an hour later, yet never re-entered sleep mode. Because the screen was dark and the fan operated silently, I had no idea it remained active while packed away, resulting in unnecessary heat buildup and significant power drain.
The next day, December 7th, that same freshly reset Ally inexplicably stopped charging overnight, halting at 54 percent capacity. Asus representatives indicated they had been unable to replicate my exact symptoms internally. Even so, with problems appearing across multiple independent units and scattered online user accounts describing similar experiences, it’s hard to believe my results are isolated. The core reason may lie within the hardware itself: the Z2 A processor inherently supports fewer sleep states than the more capable chip used in the Xbox Ally X. This limited architecture likely complicates the Windows power management process. Even the Linux-based Bazzite team reportedly had to collaborate directly with AMD engineers to properly implement sleep functionality on the Z2 A, underscoring the technical difficulty.
Why Microsoft continues to struggle with optimizing sleep on Windows for this processor remains unclear. The company has yet to provide a meaningful public explanation or detailed comment on the matter. Intriguingly, the situation differs with Intel’s Lunar Lake processor powering the MSI Claw 8 AI Plus. After manually flashing a newer, previously unavailable BIOS update, I found its sleep behavior impressively consistent. Once unreliable, the Claw 8 now consumes as little as two percent of battery capacity per day while sleeping—a substantial improvement that highlights what is possible when hardware and firmware align correctly. During Insider Preview testing, I still encountered occasional hiccups such as a black screen or a stubborn 30fps frame rate cap that required toggling performance modes to fix. Yet, those bugs are typical within beta software environments and hardly unexpected.
The Steam Deck, too, required a significant maturation period before it reached the stable, polished state we enjoy today. Perhaps Microsoft simply needs equivalent time to refine its software ecosystem to that level. Should the company truly have mastered dependable suspend-and-resume behavior on at least some configurations, and if the original white Xbox Ally remains the sole outlier, that achievement could permanently shift how enthusiasts view Windows-powered handheld gaming.
Ironically, even the standard Ally may be turning into a reasonable bargain. Its price has dropped—$489 at Amazon and $499 on Asus’s official store—and users can easily install the Bazzite operating system instead of Windows. Based on my testing, Bazzite performs more reliably, offers smoother frame delivery, and provides stronger overall efficiency, except for games encumbered by incompatible anti-cheat mechanisms or those tied exclusively to Microsoft’s “Xbox” PC ecosystem. For many players, that alternative transforms what was once a frustrating Windows handheld into a surprisingly capable portable gaming experience.
