GameSir X5s Wireless Expandable Controller Full Review & Tips

With the continuous improvement of mobile device performance, smartphones and tablets have long become an essential part of our daily entertainment. Especially tablets, with their larger screens and strong performance, they are gradually becoming the “mobile game consoles” for many players. However, touchscreen operations can never fully match the precision and tactile feedback of physical buttons.

Recognizing this pain point, various expandable controllers have appeared on the market. Today, we are reviewing the GameSir X5s Wireless Expandable Controller, which claims to instantly turn your tablet into a professional handheld device. How does it perform? Is it gimmick or real capability? Let this digital enthusiast guide you through the experience!

Love at First Sight: Unboxing and Design Details

When receiving the GameSir X5s package, a simple and elegant white box immediately caught my attention, with a clear rendering of the controller and model printed on the front. The side lists its main features. Opening the box, the X5s controller lies quietly inside, well-protected. Along with the controller, the package includes a USB-C charging cable, a protective case (with a key puller inside), two sets of silicone pads of different thicknesses, and a detailed manual. The accessories are complete and thoughtfully arranged. The controller weighs only 174 grams in the case, surprisingly lightweight. Many expandable controllers on the market are slightly heavy, but the X5s’s lightness is a bonus for long gaming sessions.

The controller’s body features a matte black finish, offering a delicate touch that resists fingerprints while increasing friction for effective anti-slip. The expandable section is smooth with no lag or looseness. Stretching from 110mm to a maximum of 213mm, it maintains excellent stability, and internal silicone pads effectively protect the device from scratches. The button layout follows the classic joystick + D-pad + ABXY layout, with function buttons (Home, Select, Start, etc.) positioned for easy blind operation.

A standout feature is its replaceable ABXY buttons. With a simple pull, you can switch between Xbox’s “YBAX” and Switch’s “XYBA” layouts, perfect for players frequently switching platforms. Joystick caps and buttons feel premium, with crisp rebound and no looseness.

Priority on Feel: Grip Experience and Ergonomics

A good controller prioritizes comfort. The GameSir X5s excels here. Its handles are ergonomically curved to fit the palm, even large hands can hold it easily. The back of the grip slightly protrudes with fine anti-slip textures, further enhancing stability and comfort. Stretching the controller fully and installing an 8.8-inch Cube iPlay3 tablet, which isn’t light, the X5s still holds it firmly without any wobble.

Once connected, the tablet’s center of gravity falls right in the middle of the controller, ensuring balanced weight distribution. Long gaming sessions won’t cause wrist fatigue—a critical point for tablet gamers, as tablets are heavier than phones. All buttons, including joysticks, D-pad, ABXY, shoulder buttons, and triggers, are within easy reach, with no need to strain fingers. Shoulder and trigger buttons are cleverly curved, allowing index and middle fingers to rest comfortably. This stable and comfortable grip ensures a solid foundation for extended immersive gameplay.

For larger tablets, users can switch silicone pads of different thicknesses for optimal comfort.

Core Technology: Hardcore Performance Analysis

The GameSir X5s is more than just appearance. Inside lies truly exciting technology. First, the Hall effect joystick. As a seasoned gamer, I’ve suffered from traditional carbon membrane joystick drift, which is frustrating (refer to Switch joystick drift issues). The X5s uses a Hall effect joystick based on magnetic sensing, providing precise positioning, completely solving drift issues, and offering a lifespan of 2 million uses. In testing, whether precise character movement in Genshin Impact or fine aiming in PUBG Mobile, the X5s joystick performs smoothly with zero dead zone precision.

Next are the Hall linear triggers. Equipped with 256-step Hall linear triggers, the X5s offers extremely accurate pressure sensitivity. In racing games, light trigger presses cause gradual acceleration, while deeper presses deliver stronger power. Throttle and brake control are more refined and layered.

The dual connection modes are another highlight. Supporting Bluetooth 5.3 and 2.4GHz wireless (sold separately), Bluetooth 5.3 ensures easy, stable, and low-latency connection with Switch, phones, and tablets. Dual ALPS linear motors provide HD vibration feedback. In Genshin Impact or Mario series games, the controller gives delicate, realistic vibration feedback, enhancing immersion. A built-in six-axis gyroscope also supports motion-sensing games.

Practical Gameplay: Tablet and Switch Handheld Experience

The iPlay3 Ultra (8.8-inch) tablet is a mobile gaming mainstay. With the X5s installed, it instantly transforms into a large-screen handheld, offering visual impact far beyond any phone. In Genshin Impact, thanks to precise Hall joysticks and linear triggers, character control is smooth for exploration and combat, and aiming accuracy improves significantly. HD vibration provides excellent feedback during skill activation.

Using a PS emulator on the phone (I used PPSSPP), loading the ISO of Castlevania: Symphony of the Night, the emulator automatically recognized the controller, no extra setup required. The X5s perfectly compensates for touchscreen limitations, giving my tablet the soul of a handheld console. Both visuals and controls reach a new level.

Nintendo Switch: Perfect Replacement and Upgrade

The X5s supports Nintendo Switch 1/2. Replacing Joy-Con, it provides refined control in games like Mario Kart 8 Deluxe, with Hall linear triggers enabling smooth acceleration and drifting. HD vibration enhances collision and speed feedback. In Zelda: Tears of the Kingdom, Hall joysticks perform stably over complex terrains and air movements, eliminating drift issues common in Joy-Con. Six-axis motion works flawlessly for shields and bow aiming.

For Switch players, X5s is not just a replacement for Joy-Con but also improves joystick and trigger precision and grip comfort, making it ideal for those seeking superior gameplay.

Convenience and Battery Life: “GameSir World” App

GameSir offers the GameSir World App, allowing firmware updates, button mapping, deadzone adjustment, macro programming, and other advanced settings, greatly enhancing controller customizability. The app is simple and intuitive, easy for beginners to navigate.

Battery life is impressive. The built-in 840mAh battery provides 8–10 hours of continuous gameplay, sufficient for a full day. USB-C charging is fast and convenient.

After in-depth experience, the GameSir X5s wireless expandable controller left a strong impression. It combines portability, comfort, and core technological innovation.
