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, much like the Hori Split Pad Pro did for the Nintendo Switch, completely changed my perspective.
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. At $149.99, I had hoped for a carrying case or at least a protective pouch. However, the box and controller packaging are, as expected from Razer, 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 – iPhones, 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 such as the iPad Mini 6th generation. While some recent telescopic controllers incorporate Bluetooth, the Kishi Ultra's USB-C connection offers superior compatibility. For this review, I tested the Razer Kishi Ultra 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 with my Steam Deck. It was recognized as a generic Xbox gamepad, yet functioned flawlessly while playing NBA 2K25 and provided satisfying rumble in games like Bakeru.
Razer Kishi Ultra Buttons, D-pad, and Triggers
Before delving into the new features, let's assess the controller's feel and performance. I had initial concerns about the d-pad, but it performed admirably 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, while the face buttons offer a satisfying click, albeit with more travel than anticipated from the original Razer Kishi.
After extensive use, including several hours-long gaming sessions (like Zenless Zone Zero while charging my phone 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 use. I'm not a fan of Chroma lighting on controllers, and like the Razer Kitsune, I would have preferred dynamic lighting that synced with on-screen gameplay.
Razer Kishi Ultra – New Features
The Razer Kishi Ultra's main attraction 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 your phone nestled in the center. This might not appeal to those seeking a compact solution, but it's not intended to be one. This 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.
Additional features include a 3.5mm headphone jack, passthrough charging (15W), and L4 and R4 shoulder buttons.
Razer Kishi Ultra iOS Limitations – 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 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.
Razer Kishi Ultra Price Point – Is It Worth It?
For most users, a wireless PS5 or Xbox controller offers a superior and cheaper wireless gaming experience on iOS. If you prefer a telescopic controller that attaches directly to your phone, the leading competitors are priced around $99.99. The Razer Kishi Ultra's $150 price tag positions it as a premium controller. Is it worth the extra cost? If you're satisfied with the pricing of the Razer Kishi and Backbone One, the added comfort justifies the higher price. However, the lack of haptics on iOS diminishes the overall experience compared to Android.
Long-term joystick drift remains a concern.
Razer Kishi Ultra – The Best Mobile Controller in 2024?
My review of Razer's previous controller can be found [here](link to previous review). Transitioning from the compact form factor I've grown accustomed to (Razer and Backbone) to this larger 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 my iPhone.
The Razer Kishi Ultra is undoubtedly the most comfortable mobile controller I've used, but its portability is a drawback. I'm concerned about its safety in my bag without the original box. It's unlikely to replace my Kishi or Backbone One for travel, and I primarily use it at home.
At this price point, I expected hall-effect analog sticks. I've experienced drift issues with various controllers, and while the Razer Kishi Ultra hasn't exhibited this yet, it's a potential concern for the future.
Having reviewed Backbone One and Razer Kishi models, I'm eager to explore the GameSir lineup.
Razer Kishi Ultra 2 Wishlist
For a future Razer Kishi Ultra iteration, aside from 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 be a worthwhile addition at this price. Finally, a carrying case would be a welcome inclusion. High-end console controllers often include such cases, and while the Kishi Ultra isn't as expensive as a DualSense Edge or Victrix Pro BFG, it would be a valuable addition.
Razer Kishi Ultra Review
If you're accustomed to full-sized controllers (PS5, Xbox Series X, etc.) and find compact mobile controllers uncomfortable, the Razer Kishi Ultra is ideal. Its comfortable grip, excellent 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 continues to improve it, including adding a carrying case.
