This April, the Razer Nexus (Free) app for iOS and Android gained support for the then-unannounced Razer Kishi Ultra controller, featuring customizable analog stick deadzones and more. Since its release, the Razer Kishi Ultra has proven its compatibility extends beyond smartphones. While undeniably the priciest mobile controller on the market (to my knowledge), it delivers unexpected features 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 revolutionized the Nintendo Switch experience, completely changed my perspective.
Razer Kishi Ultra – Package Contents
The Razer Kishi Ultra package contained the controller, several sets of rubber cushions (for various devices), stickers, and an instruction manual. Given its $149.99 price tag, I anticipated a carrying case or at least a protective pouch. However, the box and controller packaging maintained Razer's usual high quality.
The rubber cushions are paired and clearly 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.
Razer Kishi Ultra Compatibility – iPhone, Cases, Android, and iPad Mini
Unlike most telescopic mobile controllers (which typically support only iPhone and Android), the Razer Kishi Ultra also accommodates tablets like the iPad Mini 6th generation. Recent telescopic controllers have incorporated Bluetooth, but this USB-C model boasts 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 with Android or Windows devices, I did try it wired to my Steam Deck. It was recognized as a generic Xbox gamepad, functioning flawlessly with NBA 2K25 on Steam Deck and providing satisfying rumble in games like Bakeru.
Razer Kishi Ultra Buttons, D-pad, and Triggers
Before delving into its new features, let's assess the Razer Kishi Ultra's feel and performance. I initially harbored concerns about the d-pad, but it proved excellent in games like Garou: Mark of the Wolves ACA NeoGeo and newer titles such as Hades and Hitman Blood Money Reprisal. Beyond the d-pad, the shoulder buttons and triggers performed 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 (Zenless Zone Zero while charging via passthrough), I have no complaints about the Razer Kishi Ultra's d-pad, buttons, or triggers.
The textured finish, while not rubbery, provides a secure grip and remains comfortable even during prolonged 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 primary appeal lies in its full-size form factor. Unlike the compact designs of previous Razer controllers or the Backbone One, the Razer Kishi Ultra's full-size design feels like holding a high-quality console controller with your phone nestled in the center. This might not appeal to those seeking a compact solution, but that's not its intended purpose. This full-size form factor makes it the most comfortable mobile controller I've used.
Additional 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 on iOS, such as Genshin Impact.
Beyond these new features, the Razer Kishi Ultra includes 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 virtual controller mode, I hope Razer addresses the lack of haptics on 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 wireless PS5 or Xbox controller offers a superior and cheaper gaming experience on iOS. However, if you prefer a telescopic controller that attaches directly to your phone, the Razer Kishi Ultra's $150 price point significantly surpasses the typical $99.99 cost of competing models. Is the extra cost justified? If you're satisfied with the Razer Kishi or 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 of the joysticks and potential for drift remains to be seen.
Razer Kishi Ultra – The Best Mobile Controller in 2024?
Compared to Razer's more compact controllers, the transition to the full-size Razer Kishi Ultra has been interesting. Similar to the Hori Split Pad Pro for Switch, I find myself preferring both full-size and compact controllers 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 unwieldy for travel unless transported in its 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, I expected hall-effect analog sticks. 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 potential concern for future use.
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, besides hall-effect sticks, I'd like smoother edges, particularly around the passthrough charging port. While appreciating the L4 and R4 buttons, I prefer bottom-mounted paddles for better ergonomics. Adding L5 and R5 paddles with remapping options in the Razer Nexus app would be a significant improvement. Finally, a carrying case would enhance the premium feel and protect the controller during transport. While not as expensive as a DualSense Edge or Victrix Pro BFG, a carrying case would be a welcome addition.
Razer Kishi Ultra Review
If you prefer the feel of traditional 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 make it stand out. 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 this controller and includes a carrying case in future versions.
