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 admittedly the priciest mobile controller on the market, it delivers a surprisingly feature-rich experience. 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.
The Razer Kishi Ultra package contained the controller, several sets of rubber cushions for different devices, a sticker sheet, and an instruction manual. Given its $149.99 price tag, the absence of a carrying case or even a protective pouch was a slight disappointment. However, the box and controller packaging maintained 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 you use a phone case.
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, the Razer Kishi Ultra's USB-C connection boasts superior compatibility. For this review, I tested it with my iPhone 15 Pro, iPhone 14 Plus, and wired to my iPad Pro. Although 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 flawlessly while playing NBA 2K25 and provided satisfying rumble feedback in games like Bakeru.
Before delving into its new features, let's assess the controller's feel and performance. I initially had reservations 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. 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, and the face buttons offer a satisfying click, although with more travel than anticipated compared to the original Razer Kishi.
After extensive use, including several hours-long gaming sessions (playing Zenless Zone Zero while charging my phone via passthrough), I have no complaints regarding 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 feature that synced the lights with on-screen gameplay, similar to the Razer Kitsune.
The Razer Kishi Ultra's main selling point is its full-size form factor. Unlike the compact designs of previous Razer controllers or the Backbone One, the Kishi Ultra offers a full-size feel, resembling a 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 notable 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 that lack controller support outside of iOS.
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 exclusive to Android (and Windows for haptics), unavailable on iOS. While I'm not overly 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 greatly appreciate, and a similar implementation on iOS would be a welcome addition.
For most users, a wireless PS5 or Xbox controller offers a superior and more affordable gaming experience on iOS. If you prefer a telescopic controller that attaches directly to your phone, the popular 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 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.
The long-term durability and potential for joystick drift remain to be seen.
The transition from the compact form factor of previous Razer and Backbone controllers to the full-size Kishi Ultra has been an interesting experience. 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 undeniably 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, and I primarily use it at home.
At its price point, I would have preferred hall-effect analog sticks. I've experienced joystick drift with other controllers, and while the Kishi Ultra hasn't exhibited this issue yet, it's a potential concern for future use.
Having reviewed Backbone One and Razer Kishi models, I'm eager to explore the GameSir lineup.
For a future iteration, aside from hall-effect sticks, I'd like to see some design refinements, such as smoother edges around the passthrough charging port. While I appreciate the L4 and R4 buttons, I prefer bottom-mounted paddles for a more natural feel. Adding these as options, perhaps with L5 and R5 paddles and remapping capabilities within the Razer Nexus app, would enhance the premium experience. Finally, including a carrying case would be a welcome addition, aligning it with the packaging standards of high-end console controllers.
If you're accustomed to full-size controllers like those found on PS5 or Xbox Series consoles and prefer a more comfortable grip and larger buttons and sticks compared to the compact mobile controller designs, the Razer Kishi Ultra is an excellent choice. Its comfortable grip, responsive d-pad, and satisfying face buttons are highlights. The lack of full feature support on iOS is a drawback, but overall, it's a significant addition to the mobile gaming controller market. I hope Razer continues to improve upon its design and includes a carrying case for enhanced portability.
