Razer Kishi Ultra Mobile Controller Review – The Best Mobile Controller in 2024?

TouchArcade Rating: Back in April, the Razer Nexus (Free) app received an update adding support for the then-unannounced Razer Kishi Ultra controller. This controller boasts features like customizable analog stick deadzones. Since its release, the Razer Kishi Ultra has proven its compatibility extends beyond just phones. While it's currently the priciest mobile controller on the market, its feature set justifies the cost for certain devices. Having extensively used the Razer Kishi and Backbone One (including their USB-C iterations), I initially felt no need for a new controller. However, the Razer Kishi Ultra proved to be a game-changer, much like the Hori Split Pad Pro did for the Nintendo Switch.

Razer Kishi Ultra – Package Contents

The Razer Kishi Ultra's packaging included the controller, various rubber cushions for different devices (iPhone, iPad Mini 6th gen, Android), stickers, and an instruction manual. At the $149.99 price point, the absence of a carrying case or pouch was a slight disappointment. However, the box and controller packaging maintained Razer's usual high quality.

The rubber cushions are paired and clearly labeled for iPhone (Pair A), iPad Mini 6th generation (Pair B), and Android (Pair C). These are unnecessary if using a phone case.

Razer Kishi Ultra Compatibility – iPhones, Cases, Android, and iPad Mini

Unlike many mobile controllers, especially telescopic ones, which typically only support iPhones and Android devices, the Razer Kishi Ultra also supports tablets like the iPad Mini 6th generation. While some recent telescopic controllers offer Bluetooth connectivity, the Razer Kishi Ultra's USB-C connection boasts superior compatibility. For this review, I tested it on my iPhone 15 Pro, iPhone 14 Plus, and wired on my iPad Pro. While I didn't test it on Android or Windows, I did try it wired on my Steam Deck. It was recognized as a generic Xbox gamepad but functioned perfectly, demonstrating good rumble support in games like Bakeru.

Razer Kishi Ultra Buttons, D-pad, and Triggers

Before discussing new features, let's assess the controller's feel and performance. I initially had concerns about the d-pad, but it performed exceptionally well in games like Garou: Mark of the Wolves ACA NeoGeo, Hades, and Hitman Blood Money Reprisal. The shoulder buttons and triggers function flawlessly, mirroring the quality of Razer's previous controllers. The analog sticks are comfortable and smooth, while the face buttons offer a satisfying click, albeit with more travel than expected compared to the original Razer Kishi.

Overall, I have no complaints about the d-pad, buttons, or triggers after extensive use, including several hours-long gaming sessions with Zenless Zone Zero while simultaneously charging my phone via passthrough charging.

The textured finish, while not rubbery, provides excellent grip and remains comfortable even during extended use. While I'm not a fan of Chroma lighting on controllers, I would have preferred dynamic lighting that synced with on-screen gameplay, similar to the Razer Kitsune.

Razer Kishi Ultra – New Features

The Razer Kishi Ultra's primary attraction is its full-size form factor. Unlike the more compact designs of previous Razer controllers or the Backbone One, the Kishi Ultra feels like a full-sized console controller with the phone nestled in the center. This might not appeal to those seeking a compact solution, but it's not designed to be one. The full-size design makes it the most comfortable mobile controller I've used.

Other notable features include Chroma customization via the app, haptics (Android and Windows), and virtual controller mode (Android only). The virtual controller mode is beneficial for Android games that lack controller support on iOS, such as Genshin Impact.

Additional features include a 3.5mm headphone jack, passthrough charging (15W), and L4 and R4 shoulder buttons.

Razer Kishi Ultra – Missing iOS Features

Haptics and virtual controller mode are currently exclusive to Android (and Windows for haptics). While I'm less concerned about the virtual controller mode, I hope Razer implements haptics support for iOS in future updates.

Razer Kishi Ultra Price – Is It Worth It?

For most users, a wireless PS5 or Xbox controller offers a superior and more affordable wireless gaming experience on iOS. However, if you prefer a telescopic controller that directly attaches to your phone, the Razer Kishi Ultra's $150 price tag represents a premium offering compared to other options around $100. The added comfort justifies the extra cost, but the lack of haptics on iOS diminishes the overall experience compared to Android.

Long-term joystick drift remains a potential concern.

Razer Kishi Ultra – The Best Mobile Controller in 2024?

Compared to my previous experience with Razer's more compact controllers and Backbone products, the transition to the full-size Razer Kishi Ultra has been interesting. Similar to the Hori Split Pad Pro, I find myself wanting both a full-size and a more compact controller for my iPhone.

The Razer Kishi Ultra is undoubtedly the most comfortable mobile controller I've used, but its size makes it less travel-friendly. I'm hesitant to carry it in my bag without its original box. It's primarily a home-use controller for me.

At this price point, hall-effect analog sticks would have been a welcome addition. While I haven't experienced drift yet, it's a factor to consider.

I plan to review GameSir controllers in the future.

Razer Kishi Ultra 2 Wishlist

For a future iteration, I'd suggest hall-effect analog sticks and smoother edges around the passthrough charging port. While appreciating the L4 and R4 buttons, I prefer bottom-mounted paddles for better ergonomics. Adding L5 and R5 paddles with remapping options in the Razer Nexus app would be a significant improvement. Finally, including a carrying case would elevate the overall package.

Razer Kishi Ultra Review Conclusion

If you prefer the feel of full-sized controllers like the PS5 or Xbox controllers and find compact mobile controllers uncomfortable, the Razer Kishi Ultra is ideal. Its comfortable grip, excellent d-pad, and face buttons are standout features. The lack of full iOS feature support is a drawback, but it's a significant addition to the mobile controller market. A carrying case would be a valuable addition.
