GameSir G8+ MFi: Design and features<\/span><\/h3>\n\nFamiliar G8 ergonomics with a wider platform and stretch for iPad mini compatibility<\/strong><\/li>\nSwappable ABXY button caps and improved case compatibility<\/strong><\/li>\nWorks natively with both Android and iOS devices<\/strong><\/li>\n<\/ul>\nIf you’ve used the GameSir G8 Galileo, the G8+ MFi will feel immediately familiar. In fact, if you\u2019ve used an Xbox 360 or Series controller, the G8+ will feel familiar too. The full-size, contoured grips are the same chunky shape as Xbox\u2019s offering, and the same laser-engraved texturing carries over from the G8.<\/p>\n
It\u2019s noticeably comfortable to hold and feels like a proper device rather than a homebrew solution to gaming on your phone. The same overall build quality remains, too: it\u2019s robust, doesn\u2019t flex or creak, and materials feel premium.<\/p>\n
Placed side by side with its sibling, the G8+ MFi\u2019s phone deck is noticeably wider, but in isolation, I’m not sure you\u2019d actually clock the difference. It’s heavier too, at 304g versus the G8’s 252g, though again the extra weight didn’t really register during testing. The light grey-and-white colorway is an improvement from the G8 Galileo’s uniform, darker grey for my eye. It looks a little more refined in this brighter skin, but that\u2019s personal taste, and you don\u2019t get a choice anyway.<\/p>\n
The MFi certification is the headline upgrade and a welcome addition for Apple fans. Where the G8 Galileo only officially supported Android, the G8+ MFi is certified for iPhones with USB-C and the iPad mini 6 and newer. It auto-detects which platform it’s connected to and switches mode accordingly, which worked without issue across both my POCO X5 Pro 5G and iPhone 17 Pro during testing. The GameSir app recognized the controller on both phones, too, which wasn\u2019t the case with the G8.<\/p>\n
The wider stretch range, a full 30mm increase over the original, means the G8+ MFi can now accommodate an iPad mini, though without one to hand, I\u2019ll have to take GameSir\u2019s word for it. What I did appreciate was the removable magnetic back panel on the left side of the phone deck. This easily pops off to create more clearance for phones with larger camera bumps. It\u2019s a nice quality of life addition that did its job perfectly with my cased iPhone, though<\/p>\n
I\u2019m not sure what GameSir thinks I\u2019m going to do with that easily losable piece. A slot to tuck it into or even a magnetic spot on the back to stow it would have been much appreciated. I imagine we\u2019ll see a lot of G8 Plus\u2019 with a black stripe on the left side over time.<\/p>\n\n\n

I played with my iPhone case on, and the controller accommodated it comfortably, which was something I couldn’t manage on the G8 Galileo without worrying about the USB-C connector angle. It’s probably still not going to handle a chunky Otterbox, but standard slim cases are no longer a problem. For all the clever tweaks and design changes, the USB-C connector is still my favorite choice GameSir made, and I\u2019m glad it\u2019s unchanged on the G8+. It pivots freely up and down, which makes seating and removing your device a doddle.<\/p>\n
The magnetic faceplate system on the grips carries over from the G8, too, but the G8+ MFi adds swappable ABXY button caps on top of the interchangeable thumbstick options. You can physically rearrange the face button layout to match Xbox or Nintendo mapping, which is a nice complement to the software remapping available in the app. Three replacement thumbstick caps are included (short, tall, dome), but you still only get one of each.<\/p>\n\n\n

The Hall effect thumbsticks and triggers are, as far as I can tell, identical to those on the GameSir G8 Galileo.<\/p>\n
The sticks are smooth and precise with a high level of sensitivity. If you\u2019re coming from a cheaper controller, you may need some time to adjust, but increased control is certainly worth the effort.<\/p>\n
The triggers have full analog travel along with a hair-trigger mode that\u2019s snappy and reliable, perfect for shooters. If you’re upgrading from the G8, there’s no change in input quality here, which is no bad thing, but don\u2019t jump across expecting an even better experience. Deadzone and hair-trigger settings are configurable through the GameSir app, and the app now working on iOS means iPhone users get the same tuning options Android users have always had.<\/p>\n
The G8+ MFi’s d-pad has a slightly mushy wobble, though a snappy, clicky feel when you fire it off. Travel distance is short with a clear click for each direction, including diagonally. The screenshot button has been repositioned slightly further from the D-pad down compared to the G8, and the improvement was both noticeable and very welcome. I didn’t accidentally trigger it during testing, which was a recurring frustration for me previously<\/p>\n
Around the back of the G8+ are two programmable buttons, labeled M1 and M2 (compared to L4 and R4 on the last model). They’re something of a rarity for mobile controller grips at this price, with the likes of the Backbone One skipping them entirely. I found them well-sized and positioned just about perfectly.<\/p>\n
They\u2019re close to where your fingers naturally rest without getting in the way, taking just the right amount of force to avoid accidental presses. They ship unbound by default, so you’ll need the GameSir app to assign functions, and you can only mirror existing buttons on them, no macros.<\/p>\n\n\n

They work fine in the GameSir app’s test mode, delivering both strong and subtle vibrations that feel perfectly capable, if a little slow to spin up. The problem is that no game I tested, on either Android or iOS, actually utilized them.<\/p>\n
Fortnite<\/em>, Call of Duty Mobile<\/em>, Forza Horizon 5<\/em>, and Shadow of the Tomb Raider<\/em> <\/em>via Xbox cloud gaming, nothing. I believe this is actually a mobile gaming ecosystem issue rather than a GameSir problem; developers just aren\u2019t bothering or don\u2019t have the means to communicate this information to devices. That may well change in the future, but right now, don\u2019t go grabbing the G8+ expecting haptic feedback as you\u2019d get on console.<\/p>\nThe GameSir G8+ MFi features passthrough USB-C charging and a 3.5mm headphone jack, which carry over from the G8 Galileo, and both worked without issue again throughout testing. Passthrough charging reported fast charge speeds on both the POCO X5 Pro and iPhone 17 Pro with no overheating.<\/p>\n
The headphone jack remains a welcome inclusion for latency-free wired audio The dedicated GameSir button on the controller has inconsistent behavior on Android, sometimes acting as a home button and occasionally opening the GameSir app instead. On iOS, it seemed to do nothing at all, but it will light up a different color to confirm you\u2019re in the right compatibility mode for your device.<\/p>\n\n\n

Here’s how it compares to other, similar controller grips.<\/p>\n

GameSir G8+ MFi: One-minute review<\/span><\/h3>\n\nI spent a few days testing on both an iPhone 17 Pro and POCO X5 Pro<\/strong><\/li>\nI played <\/strong>Fortnite<\/strong><\/em>, <\/strong>Call of Duty Mobile<\/strong><\/em>, <\/strong>Need for Speed No Limits<\/strong><\/em>, plus <\/strong>Forza Horizon 5 and Shadow of the Tomb Raider <\/strong><\/em>via Xbox Cloud Gaming<\/strong><\/li>\nI played with the various customization options and tried to get the rumble working, unsuccessfully<\/strong><\/li>\n<\/ul>\nI approached testing the GameSir G8+ MFi with the question of not only how it fared in general, but specifically how it compared to the G8 Galileo upon which it was built. I used the same two phones and the same set of games to put them directly head-to-head. This allowed me to isolate exactly what’s changed between the two controllers and whether those changes are meaningful in practice.<\/p>\n
I tested case compatibility with a slim iPhone case, tried all swappable thumbstick and button cap configurations, checked vibration motor response across multiple games on both platforms, and verified that the GameSir app provided full functionality on both iOS and Android. I also investigated the GameSir button behavior on both operating systems and tested passthrough charging on both devices.<\/p>\n
