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 and more. Now officially released, the Razer Kishi Ultra is, to my knowledge, the most expensive mobile controller available, but it also offers impressive features and broad compatibility. Having used the Razer Kishi and Backbone One extensively, including their USB-C versions, I initially thought I didn't need another controller. However, the Razer Kishi Ultra changed my perspective, much like the Hori Split Pad Pro did for the Nintendo Switch a few years ago.
The Razer Kishi Ultra box contains the controller, several sets of rubber cushions for different devices, stickers, and an instruction booklet. At $149.99, the lack of a carrying case or pouch is a noticeable omission. However, the box and controller packaging are, as expected from Razer, of 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 you use a phone case.
Unlike many mobile controllers, especially telescopic ones, which typically only support iPhone and Android, the Razer Kishi Ultra also supports tablets like the iPad Mini 6th generation. While some recent telescopic controllers include Bluetooth, this USB-C controller boasts exceptional 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 worked flawlessly playing NBA 2K25 and also supported decent rumble in games like Bakeru.
Before discussing the new features, let's examine 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 as well as Razer's previous controllers. The analog sticks are comfortable and smooth, and the face buttons are clicky, though with more travel distance than expected.
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. I generally dislike Chroma lighting on controllers, and, similar to the Razer Kitsune, I would have preferred the lights to dynamically match on-screen gameplay.
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 feels like holding your phone within a high-quality console controller. 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 outside of iOS, such as Genshin Impact.
Additionally, the Razer Kishi Ultra includes a 3.5mm headphone jack, passthrough charging (15W), and L4 and R4 shoulder buttons.
Haptics and virtual controller mode are currently exclusive to Android (and Windows for haptics). While I'm not overly concerned about the virtual controller mode, I hope Razer will enable haptics on iOS devices. I appreciate haptic feedback on PS5 and HD Rumble on Switch, and a similar feature on iOS would be a welcome addition.
For many, a PS5 or Xbox controller used wirelessly on iOS offers a superior and more affordable option. However, if you prefer a telescopic controller that attaches directly to your phone, the Razer Kishi Ultra, at $150, represents a premium option compared to other popular choices priced around $99.99. Is it worth the extra cost? If you're satisfied with the current price point of the Razer Kishi and Backbone One, the added comfort justifies the price increase. However, the lack of haptics on iOS diminishes the overall experience compared to Android.
The long-term durability of the joysticks and potential for drift remains to be seen.
Compared to Razer's previous controllers (review available here), transitioning to this full-size controller has been an interesting experience. Similar to the Hori Split Pad Pro for Switch, I find myself wanting both a full-size and a more compact controller for iPhone.
The Razer Kishi Ultra is incredibly comfortable, but its size makes it less travel-friendly. I'm concerned about its portability unless I carry it in its original box. It's unlikely to replace my standard Kishi or Backbone One for travel, making it primarily a home-use controller.
At this price point, I had hoped for hall-effect analog sticks. I've experienced joystick drift with various controllers, and while it hasn't occurred yet with the Kishi Ultra, it's a potential concern for the future.
Having reviewed Backbone One and Razer Kishi models, I'm keen to explore GameSir controllers, which appear promising.
For a future Razer Kishi Ultra, besides hall-effect sticks, I'd like smoother edges, especially around the passthrough charging port. While I appreciate the L4 and R4 buttons, I prefer bottom-mounted paddles for a more natural feel. Adding L5 and R5 paddles with remapping in the Razer Nexus app would be a great enhancement. Finally, including a carrying case would significantly improve the overall package.
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 an excellent choice. Its comfortable grip, superb d-pad, and face buttons are highlights. The lack of full feature support on iOS is disappointing, but it's a significant addition to the mobile controller market. I hope Razer builds upon this design and includes a carrying case in future iterations.
Razer Kishi Ultra review score: 4.5/5
