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 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, much like the Hori Split Pad Pro did for the Nintendo Switch, significantly altered my perspective.
Razer Kishi Ultra – Package Contents
The Razer Kishi Ultra's packaging included the controller, various rubber cushions (for different devices), stickers, and an instruction manual. At $149.99, the omission of a carrying case or pouch felt like a missed opportunity. However, the box and controller packaging maintained 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 using a case.
Razer Kishi Ultra Compatibility – iPhone, Cases, Android, and iPad Mini
Unlike many mobile controllers (especially telescopic ones) that primarily support iPhone and Android, the Razer Kishi Ultra also accommodates tablets like the iPad Mini 6th generation. While some recent telescopic controllers offer Bluetooth, this USB-C controller 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 Android or Windows, I did try it wired on my Steam Deck. It registered as a generic Xbox gamepad but functioned flawlessly in games like NBA 2K25 and Bakeru (demonstrating decent rumble).
Razer Kishi Ultra Buttons, D-pad, and Triggers
Before discussing new features, let's assess the controller's feel and performance. My initial concerns about the d-pad proved unfounded; it performed admirably in games like Garou: Mark of the Wolves ACA NeoGeo, Hades, and Hitman Blood Money Reprisal. The shoulder buttons and triggers functioned as well as Razer's previous controllers. The analog sticks were comfortable and smooth, while the face buttons, though clicky, had more travel than anticipated compared to the original Razer Kishi.
After extensive use (including several hours playing 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 play sessions. While I'm not a fan of Chroma lighting on controllers, I would have preferred synchronized on-screen gameplay lighting, similar to the Razer Kitsune.
Razer Kishi Ultra – New Features
The Razer Kishi Ultra's main appeal lies in its full-size form factor. Unlike Razer's previous offerings or the Backbone One, it's a full-size controller, feeling like you're holding your phone within a high-quality console controller. This may not appeal to those seeking a compact solution, but it's not designed to be one. This full-size design makes it the most comfortable mobile controller I've used.
Other features include app-based Chroma customization, 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.
Additional features include a 3.5mm headphone jack, 15W passthrough charging, 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 virtual controller mode, I hope Razer implements haptics for iOS. The haptic feedback on PS5 and HD Rumble on Switch are features I appreciate, and a similar implementation on iOS would be welcome.
Razer Kishi Ultra Price Point – Is It Worth It?
For most users, a wireless PS5 or Xbox controller offers a superior and cheaper iOS gaming experience. However, for those seeking a telescopic controller that attaches to their phone, the Razer Kishi Ultra's $150 price tag represents a premium offering compared to the $99.99 price point of competitors. Is it worth the extra cost? If you're satisfied with the Razer Kishi or Backbone One, the added comfort justifies the price increase. However, the lack of haptics on iOS diminishes the experience compared to Android.
Long-term joystick drift remains a concern.
Razer Kishi Ultra – The Best Mobile Controller in 2024?
The transition from the compact form factor of previous Razer and Backbone controllers 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 exceptionally comfortable, but its portability is a concern. I worry about its safety in my bag without its original box. It's unlikely to replace my Kishi or Backbone One for travel, making it primarily a home-use controller.
The absence of hall-effect analog sticks at this price point is disappointing. While I haven't experienced drift yet, it's a potential long-term issue.
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 would be a valuable addition. Finally, a carrying case is essential for a controller at this price point.
Razer Kishi Ultra Review
If you prefer the feel of full-size controllers like the PS5 or Xbox controllers and dislike the compact size of typical mobile controllers, the Razer Kishi Ultra's comfortable grip, excellent d-pad, and face buttons make it ideal. The lack of full iOS feature support is disappointing, but it's a significant addition to the mobile controller market. Future improvements, including a carrying case, would enhance its appeal.
