Razer Kishi Ultra: Mobile Gaming Enhanced with Precision and Control

TouchArcade Rating: 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, making it, to my knowledge, the priciest mobile controller on the market. However, it delivers features exceeding expectations for specific devices. A long-time user of the Razer Kishi and Backbone One (including their USB-C iterations), I initially believed a new controller was unnecessary. However, the Razer Kishi Ultra changed my perspective, much like the Hori Split Pad Pro did for the Nintendo Switch years ago.

Razer Kishi Ultra – Package Contents

The Razer Kishi Ultra package contained the controller, several sets of rubber cushions (for different devices), stickers, and an instruction manual. Given its $149.99 price tag, I anticipated a carrying case or at least a protective pouch. Beyond that, the packaging and controller casing maintain Razer's usual high quality.

The included 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 – iPhone, Cases, Android, and iPad Mini

Unlike many mobile controllers (especially telescopic ones) that 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, this USB-C controller boasts 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 to my Steam Deck. It was recognized as a generic Xbox gamepad, but functioned flawlessly while playing NBA 2K25 on the Steam Deck. It also supports decent rumble 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 and newer titles such as Hades and Hitman Blood Money Reprisal. Beyond the d-pad, the shoulder buttons and triggers function as well as those on Razer's older controllers. The analog sticks are comfortable and smooth, while the face buttons offer a satisfying click, albeit with more travel distance than expected compared to the original Razer Kishi.

Overall, I have no complaints about the Razer Kishi Ultra's d-pad, buttons, or triggers after extensive use, including several hours-long gaming sessions (playing Zenless Zone Zero while charging my phone via passthrough charging).

The textured finish, while not rubbery, provides excellent grip and remains comfortable even during extended use. I'm not a fan of Chroma lighting on controllers, and similar to the Razer Kitsune, I would have preferred if the lights could dynamically reflect on-screen gameplay.

Razer Kishi Ultra – New Features

The Razer Kishi Ultra's primary appeal lies in its full-size form factor. Unlike Razer's previous offerings or the Backbone One, which feel compact, the Razer Kishi Ultra is full-sized, resembling a high-quality console controller with the phone nestled in the center. While this might not appeal to those seeking a compact solution, 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 (for Android and Windows), and virtual controller mode (Android only). The virtual controller mode is beneficial for Android games, as some notable titles (like Genshin Impact) lack controller support on mobile platforms outside of iOS.

Beyond these new features, the Razer Kishi Ultra includes a 3.5mm headphone jack, passthrough charging (15W), and L4 and R4 shoulder buttons.

Razer Kishi Ultra Features Missing on iOS – Haptics and Virtual Controller Mode

Haptics and virtual controller mode are exclusive to Android (and Windows for haptics) and unavailable on iOS. While I'm not overly concerned about the virtual controller mode, I hope Razer will find a way to enable haptics on iOS devices. I appreciate the haptic feedback on the PS5 and HD Rumble on the Switch, and a similar feature on iOS would be welcome.

Razer Kishi Ultra Price Point – Is It Worth It?

I believe most users are better off using a PS5 or Xbox controller wirelessly on iOS—a superior and more affordable option. If you prefer a telescopic controller that attaches to your phone, popular alternatives are priced around $99.99. The Razer Kishi Ultra's $150 price point positions it as a premium controller. Is it worth the extra cost? If you're satisfied with the current pricing of the Razer Kishi and Backbone One, the enhanced comfort justifies the added expense. However, the lack of haptics on iOS diminishes the overall experience compared to Android, where all features are fully functional.

The long-term durability of the joysticks (drift potential) remains to be seen.

Razer Kishi Ultra – The Best Mobile Controller in 2024?

If you haven't read my review of Razer's older controller, you can find it [here](insert link if available). Transitioning from the compact form factor (which I've used for years with Razer and Backbone products) to this larger controller has been interesting. Similar to the Hori Split Pad Pro for the Nintendo Switch, 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 portability is a concern. I worry about its safety in my bag unless I use the original box for transport. I'm unsure if it will replace my regular Kishi or Backbone One for travel, but I'll primarily use it at home.

At this price point, I had hoped for hall-effect analog sticks. I've experienced joystick drift with multiple controllers, and while it hasn't occurred with the Razer Kishi Ultra (or the original Kishi) yet, I can't predict the future. This is a factor to consider when purchasing.

Having reviewed Backbone One and Razer Kishi models, I'm eager to try the GameSir lineup, which seems promising. Hopefully, I'll have the opportunity soon.

Razer Kishi Ultra 2 Wishlist

Regarding potential improvements for a future Razer Kishi Ultra, besides hall-effect sticks, I'd like to see some sharper edges (like the passthrough charging port) smoothed out. While I appreciate the L4 and R4 buttons, I prefer bottom-mounted paddles for a more natural feel. Offering these as options (perhaps L5 and R5 with remapping in the Razer Nexus app) would be beneficial given the premium price. Finally, a carrying case would be a welcome addition. High-end console controllers typically include a protective case. While this controller is less expensive than a DualSense Edge or Victrix Pro BFG, a case would be a valuable inclusion.

Razer Kishi Ultra Review

If you're accustomed to playing with traditional PS5 or Xbox Series controllers (or any full-sized controller) and find the compact Joy-Con-style buttons and sticks of typical mobile controllers unsatisfactory, the Razer Kishi Ultra is ideal. Its comfortable grip, excellent d-pad, and face buttons are its strengths. The lack of full feature support on iOS is a drawback, but it's a significant addition to the mobile controller market. I hope Razer continues to improve this controller and includes a carrying case in future iterations.

Razer Kishi Ultra review score: 4.5/5
