Backbone has enjoyed relatively comfortable dominance in the iPhone controller market, but GameSir just made things considerably less comfortable. The GameSir G8 Plus MFi arrives as the company’s first MFi-certified product, bringing proven gaming hardware expertise to Apple’s ecosystem at an aggressive $79.99 price point. This puts GameSir $20 below the established market leader while matching many of its core features. The competitive landscape matters here because Backbone now faces much stronger competition from companies like GameSir, Gamevice, and Razer, making its premium positioning harder to justify. GameSir counters Backbone’s sleek design and app integration with Hall Effect technology, customizable faceplates, and dual back buttons. The G8 Plus MFi also supports both iOS and compact Android devices, offering flexibility that pure iPhone-focused controllers cannot match.
GameSir finally secured MFi certification, which means reliable performance and stable connectivity across iOS devices without the usual third-party controller jank. The company built its reputation on solid hardware, particularly with controllers like the standard G8 Plus that launched earlier this year with Bluetooth and battery support. This MFi version strips out both the battery and wireless connectivity to meet Apple’s specifications and hit that $79.99 price point. You’re getting a wired-only experience through a movable USB-C port, but the tradeoff includes pass-through charging so your phone doesn’t die mid-session. The telescopic design stretches to accommodate devices up to 215mm, which covers everything from standard iPhones to the iPad Mini, giving you way more versatility than you’d expect from a phone controller.

Hall Effect sensors in both the thumbsticks and analog triggers eliminate stick drift, which remains a persistent problem even in premium controllers. The mechanical D-pad provides tactile feedback that membrane alternatives can’t match, though the ABXY buttons use membrane technology to keep costs reasonable. Two programmable back buttons sit on laser-engraved grips, and the entire controller works with the GameSir app for customization. The detachable magnetic faceplate lets you swap thumbstick positions and rearrange the ABXY layout, something Backbone doesn’t offer at any price point. There’s also a 3.5mm audio jack for wired headphones, which matters more than you’d think when Bluetooth audio introduces latency in competitive games. GameSir clearly spent their engineering budget on components that affect gameplay rather than feature bloat.
No gyroscope means games that rely on motion controls won’t work properly, which eliminates a chunk of the iOS gaming library. The wired-only design lacks the flexibility of Backbone’s newer Pro model with its 40-hour battery and Bluetooth connectivity. GameSir’s app exists but doesn’t approach the polish or social features of Backbone’s ecosystem, which has become a genuine differentiator for the brand. Backbone built a game launcher, social platform, and recording hub that transforms the controller from a peripheral into a gaming experience. GameSir offers button remapping and firmware updates, which covers the basics but won’t replace your need for separate apps. You can tell where each company decided to compete and where they chose to concede ground.
The calculation for buyers comes down to whether Backbone’s ecosystem and brand cachet justify a 25% premium over GameSir’s hardware-focused approach. If you care about launching games from a unified interface, sharing clips with friends, or using your controller as a social hub, Backbone remains the obvious choice despite the higher cost. But if you want Hall Effect reliability, physical customization options, and the ability to use the same controller with both your iPhone and a compact Android tablet without switching devices, GameSir built exactly that product. The G8 Plus MFi proves you can compete with an established market leader by focusing on what actually matters to a specific segment of buyers. Backbone set the standard for mobile controllers on iOS, and now someone finally showed up with enough credibility to make the comparison worthwhile rather than embarrassing.
