GameSir X5s Review : Transform Your Tablet or Switch into a Pro Handheld

With the continuous improvement of mobile device performance, mobile phones and tablets have long become an important part of our daily entertainment. Especially tablets, with their larger screens and good performance, have gradually become a “mobile game console” for many players. However, touchscreen operation can never match the precision and feel of physical buttons.

It is precisely because of seeing this pain point that various stretch controllers have emerged on the market, and today we are reviewing this one — the GameSir X5s wireless stretch controller, which claims to instantly turn your tablet into a professional handheld console. How does it actually perform? Is it just hype or the real deal? Next, let me, a digital enthusiast, take you to find out!

Love at first sight: unboxing and design details

When I received the GameSir X5s package, the simple and elegant white box was the first thing to catch my eye, with a clear rendering of the controller and its model printed on the front.

The sides list the main features.

Opening the box, the X5s controller body lay quietly inside, well protected. In addition to the controller, the package also includes a USB-C charging cable, a protective case (with keycap puller inside), two sets of silicone pads with different thicknesses, and a detailed manual. The accessories are complete and thoughtfully prepared.

The controller inside the protective case weighs only 174g, which pleasantly surprised me — many stretch controllers on the market are relatively heavy, and the X5s being so lightweight is undoubtedly a plus for long gaming sessions.

The entire controller adopts a matte black finish with a fine texture that is not easy to collect fingerprints, increases friction, and effectively prevents slipping. The connection of the stretch part is very smooth, with no jamming or looseness at all. Even when stretching from 110mm to the maximum 213mm, it still maintains good stability, with silicone pads inside to effectively protect the device from scratches.

In terms of button layout, the X5s uses the classic joystick + D-pad + ABXY configuration, with function buttons (Home, Select, Start, etc.) placed reasonably for easy blind operation.

What really caught my eye was its replaceable ABXY button design. With a gentle pull, you can freely switch between Xbox’s “YBAX” and Switch’s “XYBA” layouts. For someone like me who often switches between platforms, this is a blessing — no more adapting to different button layouts. The joystick caps and button materials feel premium, with crisp rebound and no looseness.

Feel comes first: grip experience and ergonomics
For a good controller, grip feel is paramount. The GameSir X5s excels in this aspect. The grip handles are designed with ergonomic curves that fit the palm well, making it easy to hold even for my large hands. The back of the grips is slightly raised with fine anti-slip texture, further improving stability and comfort.

I stretched the controller to its maximum and installed my 8.8-inch Cube tablet. Although the Cube PalmPlay 3 is not light, the X5s could still hold it firmly without any wobble.

After connection, the tablet’s center of gravity falls exactly in the middle of the controller, making the overall weight distribution very balanced. Even after long periods of gaming, my wrists did not feel fatigued. This is especially important for tablet players, as tablets are much heavier than phones.

All buttons — including the joystick, D-pad, ABXY, shoulder buttons, and triggers — are within easy reach when holding the controller, with no need to stretch fingers. The shoulder and trigger buttons are cleverly designed with a natural curve so the index and middle fingers rest comfortably. This comfortable and stable grip lays a solid foundation for long immersive gaming sessions.

If the tablet size is large, you can swap in pads of different thickness for the best grip experience.

Core technology: hardcore performance analysis
The GameSir X5s is not just about looks — the tech inside is what’s truly exciting.

First is the Hall effect joystick. As a veteran gamer, I’ve been plagued by the “drift” problem of traditional carbon film joysticks (see Switch joystick drift). The X5s uses Hall effect joysticks with magnetic induction for precise positioning, completely solving joystick drift, and offers a lifespan of up to 2 million uses. In actual tests, whether precise character movement in Genshin Impact or fine crosshair adjustments in PUBG Mobile, the X5s joysticks showed impressive smoothness and zero-deadzone accuracy.

Next is the Hall linear trigger. The X5s features 256-level Hall linear triggers with high pressure sensitivity. In racing games, a light press makes the car accelerate slowly, while a deep press delivers stronger power output. Throttle and brake control becomes more refined and layered.

Dual connection mode is also a highlight of the X5s. It supports both Bluetooth 5.3 and 2.4GHz wireless connection (dongle sold separately). Bluetooth 5.3 is convenient for connecting to Switch, phones, and tablets, with stable connection and ultra-low latency, almost unnoticeable.

The dual ALPS linear motors provide HD vibration feedback, an icing on the cake. In Genshin Impact when triggering elemental bursts, or when taking hits in Mario series games, the controller gives delicate and realistic vibrations. Different vibration modes and intensities transmit in-game impact directly to the hands, greatly enhancing immersion. The built-in six-axis gyroscope also supports motion-controlled games.

In the field: deep handheld-style experience on tablet and Switch

8.8-inch tablet: my new handheld favorite
My PalmPlay 3 Ultra (8.8 inches) tablet has always been my main mobile gaming device. With the GameSir X5s installed, it instantly transformed into a large-screen handheld — a visual impact no phone can match.

Genshin Impact: Thanks to the precision of the Hall joystick and the linearity of the Hall trigger, I could explore and fight more smoothly. Aiming accuracy improved greatly, removing the clumsiness of touchscreen aiming. HD vibration provided great feedback during skill releases.

Opening the PS emulator on my phone (I used the common PPSSPP emulator, though games like Castlevania: Symphony of the Night are PS titles, many Android emulators like DuckStation and ePSXe work well), loading the ISO file — the emulator automatically recognized the controller with no extra setup, and I could play instantly.

The X5s perfectly makes up for the shortcomings of tablet touch controls, truly giving my tablet the soul of a handheld, with both visual and control experience reaching a new level.

Nintendo Switch: perfect replacement and upgrade
Besides tablets, the X5s supports Nintendo Switch (1st/2nd gen). I used it to replace the Switch’s original Joy-Con.

In Mario Kart 8 Deluxe, the Hall linear trigger’s fine control over acceleration and drifting lets me master racing rhythms with confidence, and HD vibration makes collisions and acceleration feel more realistic. In The Legend of Zelda: Tears of the Kingdom, the Hall joystick was stable during movement and airborne actions over complex terrain, without the drift problem common to Joy-Cons. Motion control worked perfectly for shield raising and bow aiming, smooth and precise.

In the comparison shot of Luigi’s Mansion 2 gameplay between the GameSir X5s and Joy-Cons, for Switch players, the X5s is not only a perfect Joy-Con replacement, but also brings significant improvements in joystick and trigger precision and grip comfort, making it an ideal choice for those seeking a better gaming experience.

Convenience: “GameSir World” app and battery life
GameSir also offers the GameSir World app, which allows firmware upgrades, button mapping, deadzone adjustment, macro programming, and other advanced settings — greatly increasing playability and customization. The app interface is simple and intuitive, easy even for beginners.

In terms of battery life, the built-in 840mAh battery is satisfying. In my days of intensive testing, it could support 8–10 hours of continuous play, enough for a full day of gaming.

It charges via standard USB-C, making charging quick and convenient.

Conclusion and buying advice
After in-depth experience, the GameSir X5s wireless stretch controller left a deep impression. It not only considers portability and comfort in its design, but also makes innovative breakthroughs in core technology — especially with the Hall effect joystick and trigger, solving key gamer pain points and bringing a qualitative leap.
