Just when you thought GameSir couldn’t possibly come out with any more new form factors, that’s when they surprise you. The GameSir X4 Alerion isn’t quite like anything we’ve seen from the company before. It’s a two-piece mobile controller that connects to your phone via bluetooth that’s also officially licensed by Xbox. 

First of all, that name is so badass. So we had to learn where it came from. A quick Google search says Alerion means “Heraldry. an eagle displayed, usually represented without a beak or legs.” Fitting because the Alerion controllers clip to your smartphone like wings. Pretty neat.

Like most GameSir products, the packaging is pretty generous. Outside of the magnetically-attached two-piece controllers, you’ll also find the carrying case with alternate thumbsticks and D-Pad. You also get some stickers as well as a GamePass subscription code. 

With GameSir, you’ll never feel like you’re not getting your money’s worth. 

Features and Specs 

Like most of GameSir’s recent offerings, the X4 Alerion comes with Hall Effect sticks. That means no risk whatsoever of stick drift. Other than the D-Pad, the AXBY face buttons are also interchangeable. 

You have more customization options through the GameSir app so if you’re the type who likes tweaking their devices, you’ll have plenty to do with the Alerion. You can adjust trigger mode, RGB brightness, lighting effects, volume and key value freely.

Actual use and performance

It’s a pretty straightforward device. Snap the controllers onto your Android smartphone, pair via bluetooth, and you’re ready to play. 

It was perfect when we used it with the Samsung Galaxy S24 Ultra. The controller snapped on to the sides without trouble. We then proceeded to play Pokémon Unite and Call of Duty: Mobile. 

It worked seamlessly with no noticeable delay on Pokémon Unite. It’s a different story for CODM though. While it did work right away, there was a bit of delay in the input which affected our gameplay. 

We also tried it with Asphalt 9 — it’s a game that’s known to work well with mobile controllers. With the X4 Alerion, it was no different. They worked together perfectly. 

It’s good to check first if the game you intend to play has controller support. If that’s the case, the X4 Alerion will work right off the bat. Without controller support, you’ll have to resort to button mapping. It’s not our favorite activity in the world, but if you’re hellbent on playing with physical controls, it’s something you just have to do. 

GameSir was kind enough to make their own tutorial video about this. Watch below: 

Not for every smartphone

While the X4 Alerion is a great mobile gaming partner for regular slabs, foldable users who want to play with the screen unfolded might have to turn to other offerings from GameSir. The clip at the top of each controller just isn’t tall enough to accommodate larger screens. You can, of course, still use it folded so there’s that option. 

Another pain point would be for those smartphones with huge, protruding camera modules. We tried clipping the X4 Alerion on the HONOR Magic6 Pro and well, it was an exercise in futility. It just doesn’t fit securely and would disconnect the bluetooth connection every time it gets yanked out unintentionally.

That said, it’s perfect for everything else. For best results, use the GameSir X4 Alerion with Android smartphones meant for gaming. Those tend to not have bulky camera modules and are more built for mobile gaming.
