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 the priciest mobile controller I've encountered, its feature set justifies the cost for specific devices. 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 surprised me, much like the Hori Split Pad Pro did for the Nintendo Switch years ago.
Razer Kishi Ultra – Package Contents
The Razer Kishi Ultra packaging included the controller, several sets of rubber cushions (for different devices), stickers, and an instruction manual. Given its $149.99 price tag, a carrying case or pouch would have been a welcome addition. 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 are unnecessary if you use a phone 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, the 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 connect it to my Steam Deck. It was recognized as a generic Xbox gamepad, functioned flawlessly while playing NBA 2K25, and offered satisfying rumble in games like Bakeru.
Razer Kishi Ultra Buttons, D-pad, and Triggers
Before discussing the 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. Beyond the d-pad, the shoulder buttons and triggers function as well as Razer's previous controllers. The analog sticks are comfortable and smooth, while the face buttons provide satisfying clicks, 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 charging), 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. 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 main selling point is its full-size form factor. Unlike the 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 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.
Additionally, 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). While I'm not overly concerned about the virtual controller mode, I hope Razer implements haptics support for iOS. I appreciate haptic feedback on the PS5 and HD Rumble on the Switch, and a similar feature on iOS would be a welcome addition.
Razer Kishi Ultra Price Point – Is It Worth It?
For most users, a PS5 or Xbox controller offers a superior and cheaper wireless option for iOS. If you prefer a telescopic controller that attaches to your phone, the popular alternatives are usually 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 Razer Kishi or Backbone One's price, the added comfort justifies the upgrade. 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.
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 for 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 portability is a concern. I worry about its safety in my bag unless I use the original box. It's unlikely to replace my Kishi or Backbone One for travel, making it primarily a home-use controller.
At this price point, hall-effect analog sticks would have been expected. I've experienced joystick drift with other controllers, and while it hasn't occurred with the Kishi Ultra 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 iteration, 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 these as options (perhaps L5 and R5 with remapping) would enhance the premium experience. Finally, including a carrying case would complete the package.
Razer Kishi Ultra Review
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 significant advantages. The lack of full feature support on iOS is a drawback, but it's a valuable addition to the mobile controller market. I hope Razer continues to improve it and includes a carrying case.
