The GameSir G8+ Galileo enters a crowded market of mobile gaming controllers, but it comes armed with some serious strengths. It’s big, bold, and meant to mimic the full-sized Xbox experience in a mobile form factor. Unlike many competitors, the G8+ uses Bluetooth, making it compatible with iPhone, Android, and Switch. But does its versatility come at a cost?
In this hands-on review, we test out the GameSir G8+ across multiple platforms and games to see if it truly delivers. Spoiler alert: it does, with a few trade-offs. If you’re okay with the extra weight and size, this could be one of the most comfortable and powerful mobile gaming controllers available right now.
With Hall Effect sticks, customizable back buttons, motion controls, and excellent build quality, this controller makes a strong case for itself.

Unboxing Included Accessories:
Inside the box, you’ll find the controller, a USB-C to USB-A cable, and several interchangeable thumbsticks. These include two standard concave sticks, one taller concave stick for added precision, and a GameCube-style rounded stick for those who prefer a retro feel. There’s also a tiny short stick that offers lower resistance.
The analog sticks pop off easily thanks to magnetically attached shells. Beneath the controller, you’ll find a small box with documentation, a quick start guide, and a decent-quality USB-C cable. Everything is packaged securely and with minimal waste. No carry case is included, which feels like a missed opportunity given the controller’s size and premium intentions.
Design & Build Quality:
The G8+ immediately resembles an Xbox controller, down to the shape of its bumpers and triggers. It adopts the familiar ABXY layout and a clicky D-pad, similar to what you’d find on an Xbox One controller. However, the D-pad here is springier with slightly more resistance.
The thumbsticks, powered by Hall Effect sensors, feel smooth and responsive. They’re lighter to the touch than standard Xbox sticks but support L3/R3 clicks and are modular. The front face is clean, and the button labeling can be swapped—a nice touch for personalization.
The hand grips are larger and more bulbous than those on traditional controllers, adding comfort during long sessions. The build quality is outstanding—no flexing or creaking—and the materials feel premium without being overly glossy. The rear of the controller houses two well-placed back buttons and an “M” programming button. At 11 ounces, it’s heavier than most competitors but feels very balanced in hand.
Though not pocketable, the G8+ feels like a true console-grade controller. It’s big, but not clumsy. Ports, seams, and button response all show a high level of manufacturing precision.
Back Buttons & Customization:
The G8+ features two rear programmable buttons that are among the most comfortable and responsive on any mobile controller. Programming them is simple: hold the M button and the desired back button until the light blinks white, then input any combination of face or shoulder buttons.
Press the back button again to save the sequence. The back buttons support macros, so a quick tap can perform complex input sequences. Unlike the Steam Deck’s stiff back buttons, these are soft and responsive with no accidental activations.
Their placement is natural, enhancing gameplay without disrupting grip. This feature adds value for pro gamers and accessibility-focused users alike. Button labels on the controller can also be swapped to match your preferred system or layout.
Motion Control & Vibration:
The G8+ includes a built-in gyroscope, allowing for motion control with compatible devices like the Nintendo Switch. It’s responsive and accurate in games that support tilt aiming or steering. Vibration motors are present as well, delivering subtle but effective feedback. They’re not overbearing but help immerse you during action-packed moments.
The level of force feedback feels tuned for mobile platforms, offering a happy middle ground between overdone rumbles and total absence. While vibration is supported across platforms, intensity settings are not adjustable in the current firmware. Still, it’s nice to have both motion and vibration packed into a third-party controller.
Connectivity & Device Support:
The GameSir G8+ connects via Bluetooth or USB-C, depending on your device. It supports iPhones (Lightning or USB-C with adapter), Android phones, and the Nintendo Switch. The pairing process is simple: just open the controller and it automatically powers on and connects to the last used system.
Manual pairing requires pressing the bottom-left function button with a face button tied to your desired platform. The Bluetooth signal is stable with minimal latency. USB-C offers a wired connection for Switch and Android. Unfortunately, there’s no passthrough charging or headphone jack, which may be a downside for some users. But the wide compatibility is a big plus.
Comparison to Backbone One Controller:
The most obvious comparison here is with the Backbone One. While the Backbone wins on sleekness, portability, and integrated iOS features, the G8+ beats it in comfort, compatibility, and customizability. The Backbone requires a direct Lightning or USB-C connection and only works with supported phone sizes, whereas the G8+ has a generous expansion slot that fits larger phones and even small tablets.
The feel in-hand is closer to a true Xbox controller than the Backbone’s flatter profile. In terms of latency, the Backbone does have an edge due to its wired connection, but the G8+’s Bluetooth connection is surprisingly fast and stable.
It even auto-connects when opened, similar to the Backbone’s plug-and-play experience. The extra bulk is a trade-off, but for those who prioritize ergonomics and platform flexibility, the G8+ takes the win.
Drawbacks & Trade-offs:
Despite its strengths, the G8+ has a few drawbacks. Its size and weight make it less portable—at 11 ounces plus phone, it can feel top-heavy. It’s not pocket-friendly, and its expanded form factor might not appeal to on-the-go users. There’s also no headphone passthrough or power delivery while in use, which limits its utility during long gaming sessions.
The D-pad and right analog stick are slightly pushed outward, making them less natural for FPS games or extended D-pad use. And although Bluetooth connectivity is solid, it lacks the ultra-low latency of a wired connection. Lastly, the controller grip without a phone case can feel just shy of 100% secure; the grip is solid, but not unshakable.
Battery Life:
Battery life on the G8+ is solid. In a week of daily testing across iPhone and Switch, we only needed to charge it once. The controller automatically powers on when opened and turns off when closed, saving energy and streamlining the experience. Charging is done via USB-C and takes about 2 hours for a full charge.
GameSir doesn’t specify the exact battery size, but usage suggests a reliable 15–20 hours per full charge depending on vibration use and connection type. For most players, that means days of gaming before needing to recharge.
Price & Value:
The GameSir G8+ currently sells for around $80, often with discounts available online. For what you get—Hall Effect sticks, back buttons, motion controls, and wide compatibility—it offers excellent value. It’s noticeably cheaper than the Backbone One while being more versatile and comfortable for long sessions.
If you frequently switch between Android, iOS, and Nintendo Switch, this is one of the few controllers that handles all three with minimal compromise. Considering the build quality and features, the price is well justified. The only thing missing is a carry case, which would round out the premium package.
