GameSir X3 Pro review: the most complete controller for mobile phones

There are more and more people who play with their mobile phones. The video game market for smartphones has not stopped growing in recent years, although there is still something in which mobile phones are quite far from portable consoles.

And no, it is not the issue of power. In fact, with the best cell phones on the market you can enjoy very demanding gameswith ray-tracing and so on. Even with cloud services like GeForce Now and Xbox Cloud Gaming, you can play triple-A console games from your phone.

So what’s the problem? Well comfort when playing from mobile. And the touch controls on the screen and how unergonomic it is to hold the mobile horizontally are the two big obstacles that ruin the experience when playing.

To this we must add the overheating of long gaming sessions that not only affects performance, but also makes holding the phone uncomfortable. Luckily, the brand Lord of the game has launched a controller that solves these two problems.

We are talking about Game Sir X3 Prothe brand’s new mobile remote control that we have tested and loved: it includes a cooling fan, grips, Hall effect joystick and microswitch buttons that give a mechanical sensation when pressed.

Next, we analyze in depth the new GameSir X3 Pro and we tell you everything about this controller that seemed crazy to us.

GameSir X3 Pro review: a mobile controller with cooling, grips and advanced controls

The new GameSir X3 Pro is a improved version of the GameSir X3 (which we also tested). This is a style command “Nintendo Switch” in which You place the mobile in the center and connect it via USB-C. This means that you can use it with any Android or with the iPhone 15 and 16 series.

Besides, fits the size of any phone thanks to its adjustable system that allows you to contract or expand the controller to attach it to devices between 4.33 and 7.09 inches. In fact, it doesn’t take you even a minute to install it. Even a child could attach this remote control to a mobile phone.

Now, the design is not the only thing we loved about this controller. Below we leave you a technical sheet with all its features and then we will tell you all the things that make the GameSir X3 Pro the most complete mobile remote control What is currently on the market:

What is the GameSir X3 Pro controller like?

From the moment I opened the box of the GameSir X3 Pro I knew I was looking at a high quality product. And the first thing you find is a case for him command and many accessories. I loved this detail, there are few controls that come with a case and it will help me carry it protected anywhere.

Now, speaking of the command, it has a great manufacturing quality: It feels quite solid to the touch and the finishes in each of its details are very good. It doesn’t feel like one of those cheap controllers that break down quickly.

How to use it? Well it is “Plug and play”, that is to say, No configuration needed, just plug it in and you start playing. And if you are worried about the phone’s battery, you should know that it has a dual-function USB-C port to turn on the fan and charge your phone while playing simultaneously.

Another thing that surprised me is that includes a headphone jackwhich is a very appreciated extra. There are fewer and fewer phones that come with this port. And speaking of the gaming featuresIt must be said that it has rgb lights on the fan, haptic response thanks to its vibration motors and the following qualities that I liked the most:

Joysticks with Hall Effect, gyroscope, buttons and microswitch triggers

The Game Sir X3 Pro It is the best controller to play on mobile phones. And I don’t say it in vain. It truly brings the most advanced control setup you can find on the market.

For a start, all its buttons are microswitchesboth the ABXY and the triggers and the D-Pad or crosshead. This means that when you press a button you are not operating a touch membrane like in most controls (which is usually imprecise and easily damaged).

Each button has its own mechanical switch (microswitch) that offers greater precision than the touch membrane. And this is very noticeable. Pressing a button is more satisfyingsince it gives a kind of feeling “click” quite pleasant.

To this we must add that buttons are customizable and programmable. In its case it includes replacements for the crosshead and joysticks that are easily exchanged. And with the GameSir app you can map the control and customize the buttons.

Besides, Its joysticks are more advanced than those of Xbox or PlayStation. This is thanks to the fact that they have Hall Effect, a technology that detects movement through an electromagnetic field. Thus, since they do not depend on friction like analog joysticks, they are much more precise, durable and do not suffer from “drift”the number one enemy of gamers.

And if that were not enough, it has 6 axis gyroscope. Thanks to it, I was able to have better precision when playing shooters on mobile. Also, for racing games it is incredible: you control movement by simply tilting the controller to the right or to the left.

Detachable grips that will give you the feeling of playing with a portable console and not with a mobile phone

For me a one of the best things about this controller They are their removable handles. Because no, it is not ergonomic to hold a rectangular device horizontally in your hands for a long time. In fact, I usually slip my phone in this position (I’ve stamped it on my face a couple of times).

Therefore, it has a pair of handles that you can put on or take off in a few secondsIt seemed to me to be a very important success. If you put them on you can get a much more ergonomic grip that gives you the feeling of holding a console controller of all life.

But if you get tired and want a tighter grip, you can remove the handles to have a more compact control. This can be very comfortable if you are in a long gaming session and want to reduce the spread of your arms when holding it.

Best of all: its integrated cooling system with a powerful 12W fan

Finally, I have to tell you about the controller’s star feature: its integrated cooling system. It is a 900 mm² cooling plate cooled by a 12 W fan of power. The plate is in contact with the mobile and achieves incredible heat dissipation.

So that you understand the cooling power of the GameSir X3 Pro, I tell you that I tested it in long sessions with different games. I turned on the fan when I felt the phone was overheating and on average it drops between 15 °C and 10 °C in a matter of minutes, also managing to recover the performance lost due to high temperature.

Of course, there was something I didn’t like of this cooling system: the fan does not have a built-in battery, so it depends entirely on USB-C charging. That is to say, you can only use it connected to the current.

Is the GameSir X3 Pro controller worth it?

I’m not going to make it any longer, the GameSir X3 Pro It is the best remote you can buy for your mobile. It’s that simple! It’s amazing and it’s well worth getting it if you want to have the best gaming experience on your smartphone.

Not only does more ergonomic your gaming sessionsalso gives you advantage when playing thanks to its advanced controls worthy of an eSports player and its improved performance through cooling.

The best of all is that its price is not crazy (for the best controller on the market) and you have different options to buy it on sale. The GameSir X3 Pro is worth €89.99 and can be purchased on Amazon with 10% discount using the coupon GAMESIRX3P and this button:
