This 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 and more. 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 specific devices. As a long-time user of 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 package includes the controller, several sets of rubber cushions for different devices, stickers, and an instruction manual. Given its $149.99 price tag, the absence of a carrying case or pouch is a notable omission. However, the box and controller packaging maintain Razer's usual high quality.
The rubber cushions are paired and labeled for iPhone (Pair A), iPad Mini 6th generation (Pair B), and Android (Pair C). These cushions are unnecessary if using a protective case.
Razer Kishi Ultra Compatibility – iPhones, Cases, Android, and iPad Mini
Unlike many mobile controllers, particularly 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 seems to offer superior compatibility. For this review, I tested it with my iPhone 15 Pro, iPhone 14 Plus, and wired to 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, functioning well in games like NBA 2K25 and demonstrating decent rumble in titles such as Bakeru.
Razer Kishi Ultra Buttons, D-pad, and Triggers
Before delving into new features, let's assess the controller's feel and performance. My initial concerns about the d-pad proved unfounded; it performed exceptionally well in games like Garou: Mark of the Wolves ACA NeoGeo, Hades, and Hitman Blood Money Reprisal. Beyond the d-pad, the shoulder buttons and triggers function as smoothly as those on Razer's previous controllers. The analog sticks are comfortable and responsive, while the face buttons offer a satisfying click, albeit with more travel than anticipated.
After extensive use, including several hours-long gaming sessions (e.g., Zenless Zone Zero while charging via passthrough), I have no complaints about the d-pad, buttons, or triggers.
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 a dynamic lighting system that responds to on-screen gameplay, similar to the Razer Kitsune.
Razer Kishi Ultra – New Features
The Razer Kishi Ultra's main attraction is its full-size form factor. Unlike the more compact designs of previous Razer controllers or the Backbone One, the Kishi Ultra provides a full-size feel, resembling a high-quality console controller with the phone nestled in the center. This might not appeal to those seeking a compact solution, but it's not intended to be one. The full-size design makes it the most comfortable mobile controller I've used.
Other 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, 15W passthrough charging, and L4 and R4 shoulder buttons.
Razer Kishi Ultra iOS Limitations – Haptics and Virtual Controller Mode
Haptics and virtual controller mode are currently exclusive to Android (and Windows for haptics) and unavailable on iOS. While I'm less concerned about the virtual controller mode, I hope Razer will implement haptics support for iOS devices. The haptic feedback on PS5 and HD Rumble on Switch are features I appreciate, and a similar implementation on iOS would be a welcome addition.
Razer Kishi Ultra Price Point – Is It Worth It?
For most users, a wireless PS5 or Xbox controller offers a superior and more affordable wireless solution for iOS. If you prefer a telescopic controller that attaches directly to your phone, the leading alternatives are priced around $99.99. The Razer Kishi Ultra's $150 price point positions it as a premium controller. Is the extra cost justified? If you're satisfied with the current pricing of the Razer Kishi and Backbone One, the added comfort makes the upgrade worthwhile. However, 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 Razer's previous, more compact controllers, the transition to the full-size 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 concerned about its portability unless carried in its original box. It's unlikely to replace my Kishi or Backbone One for travel, making it primarily a home-use controller.
The lack of hall-effect analog sticks at this price point is disappointing. While I haven't experienced drift yet, it's a potential long-term concern.
Having reviewed Backbone One and Razer Kishi models, I'm eager to explore GameSir's offerings.
Razer Kishi Ultra 2 Wishlist
For a future Razer Kishi Ultra iteration, I'd prioritize hall-effect analog sticks and smoother edges around the passthrough charging port. While I appreciate the L4 and R4 buttons, I prefer bottom-mounted paddles for better ergonomics. Adding L5 and R5 paddles with remapping in the Razer Nexus app would be a significant enhancement. Finally, including a carrying case would elevate the overall package.
Razer Kishi Ultra Review
If you prefer the feel of full-size controllers like those found on PS5 or Xbox Series consoles and find compact mobile controllers less comfortable, the Razer Kishi Ultra is ideal. Its comfortable grip, excellent d-pad, and face buttons are its strengths. The limited feature support on iOS is a drawback, but it's a significant addition to the mobile controller market. I hope Razer addresses this and includes a carrying case in future iterations.
