This April, the iOS and Android Razer Nexus app (free) 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 it's currently the priciest mobile controller on the market, its feature set justifies the cost for specific devices. A long-time user of Razer Kishi and Backbone One controllers (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 changed my perspective.
Razer Kishi Ultra – Package Contents
The Razer Kishi Ultra package included the controller, various rubber cushions for different devices (iPhone - Pair A, iPad Mini 6th gen - Pair B, Android - Pair C), stickers, and an instruction manual. Given its $149.99 price tag, the omission of a carrying case or pouch was a slight disappointment. However, the box and controller packaging maintained Razer's usual high quality.
The rubber cushions are paired and clearly labeled for compatibility with specific devices. These cushions are unnecessary if using a phone case.
Razer Kishi Ultra Compatibility – iPhone, Cases, Android, and iPad Mini
Unlike many mobile controllers, particularly telescopic ones, which typically support only iPhone and Android, 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 appears to boast superior compatibility. For this review, I tested it with my iPhone 15 Pro, iPhone 14 Plus, and wired to my iPad Pro. While I didn't test Android or Windows compatibility, I did try it wired to my Steam Deck. It was recognized as a generic Xbox gamepad, functioning well in games like NBA 2K25 and providing satisfying rumble feedback in titles such as Bakeru.
Razer Kishi Ultra Buttons, D-pad, and Triggers
Before discussing new features, let's examine the controller's feel and performance. My initial concerns about the d-pad proved unfounded; 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 functioned flawlessly, mirroring the quality of Razer's previous controllers. The analog sticks were comfortable and smooth, while the face buttons, although clicky, had more travel distance 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. While I'm not a fan of Chroma lighting on controllers, and similar to the Razer Kitsune, I would have preferred the lights to dynamically reflect on-screen gameplay.
Razer Kishi Ultra – New Features
The Razer Kishi Ultra's main appeal lies in 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 high-quality 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 (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, 15W passthrough charging, and L4 and R4 shoulder buttons.
Razer Kishi Ultra iOS Feature Limitations – Haptics and Virtual Controller Mode
Haptics and virtual controller mode are currently exclusive to Android (and Windows for haptics), unavailable on iOS. While I'm less 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 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. However, if you prefer a telescopic controller that directly attaches to your phone, the Razer Kishi Ultra's $150 price point represents a premium offering compared to other popular options at $99.99. Is the extra cost justified? If you're satisfied with the current pricing of the Razer Kishi and Backbone One, the enhanced comfort makes the upgrade worthwhile. However, the lack of haptics on iOS diminishes the overall experience compared to Android, where the full feature set is available.
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 controllers, the transition to the larger form factor has been interesting. Similar to the Hori Split Pad Pro for the 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. Its size makes it less ideal for travel unless carried in its original box. It's unlikely to replace my regular Kishi or Backbone One for travel, relegating its use primarily to home gaming.
At this price point, hall-effect analog sticks would have been a welcome addition. I've experienced joystick drift with various controllers, and while the Razer Kishi Ultra hasn't exhibited this issue yet (nor has the original Kishi), it's a factor to consider.
Having reviewed Backbone One and Razer Kishi models, I'm eager to explore the GameSir lineup, which seems promising.
Razer Kishi Ultra 2 Wishlist
For a future Razer Kishi Ultra iteration, besides hall-effect sticks, I'd suggest smoothing out some of the sharper edges, particularly around the passthrough charging port. While I appreciate the L4 and R4 buttons, I prefer bottom-mounted paddles for a more natural feel. Including these as options, perhaps even adding L5 and R5 paddles with remapping capabilities in the Razer Nexus app, would enhance the premium experience. Finally, a carrying case would be a valuable addition, mirroring the inclusion of hard cases with high-end console controllers. While not as expensive as a DualSense Edge or Victrix Pro BFG, a case would be a relatively inexpensive yet appreciated improvement.
Razer Kishi Ultra Review
If you're accustomed to full-sized controllers like those found on PS5 or Xbox Series consoles and prefer a more substantial feel over the compact designs common in mobile controllers, the Razer Kishi Ultra is an excellent choice. Its comfortable grip, responsive d-pad, and satisfying face buttons make it a joy to use. The lack of full feature parity on iOS is disappointing, but the Razer Kishi Ultra is a significant addition to the mobile controller market. I hope Razer continues to improve upon this design and includes a carrying case in future iterations.
