Razer Kishi Ultra Mobile Controller Review – The Best Mobile Controller in 2024?

TouchArcade Rating: This April, the iOS and Android Razer Nexus (Free) app 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 arguably the priciest mobile controller on the market, its feature set justifies the cost for compatible 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, has completely changed my perspective.

Razer Kishi Ultra – Package Contents

The Razer Kishi Ultra package includes 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 absence of a carrying case or pouch is a notable omission. However, the box and controller packaging maintain Razer's usual high quality. The rubber cushions are paired and clearly labeled for optimal device compatibility. Cases render these cushions unnecessary.

Razer Kishi Ultra Compatibility – iPhones, Cases, Android, and iPad Mini

Unlike most telescopic mobile controllers (primarily supporting iPhones and Android devices), the Razer Kishi Ultra also embraces tablets like the iPad Mini 6th generation. Recent telescopic controllers have incorporated Bluetooth, but the Kishi Ultra's USB-C connectivity boasts superior compatibility. For this review, I tested the controller with my iPhone 15 Pro, iPhone 14 Plus, and wired to my iPad Pro. While I didn't test Android or Windows compatibility directly, I did connect it wired to my Steam Deck. It registered as a generic Xbox gamepad, functioned flawlessly in NBA 2K25, and delivered satisfying rumble in titles like Bakeru.

Razer Kishi Ultra Buttons, D-pad, and Triggers

Before delving into new features, let's assess the core functionality. 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 mirror the responsiveness of Razer's previous controllers. The analog sticks offer a comfortable, smooth experience, while the face buttons, despite their increased travel distance, remain satisfyingly clicky.

After extensive use, including several hours-long gaming sessions (e.g., 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 prolonged use. While I'm not a fan of Chroma lighting on controllers, I would have preferred dynamic lighting synchronization with on-screen gameplay, similar to the Razer Kitsune.

Razer Kishi Ultra – New Features

The Razer Kishi Ultra's primary allure is its full-size form factor. Unlike the compact designs of previous Razer controllers or the Backbone One, the Kishi Ultra provides a full-sized feel, resembling a 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 key 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/R4 shoulder buttons.

Razer Kishi Ultra iOS Feature Limitations – Haptics and Virtual Controller Mode

Haptics and virtual controller mode are exclusive to Android (and Windows for haptics), absent from the iOS version. While I'm less concerned about virtual controller mode, the lack of haptics on iOS is a significant drawback. Given my appreciation for haptic feedback on PS5 and HD Rumble on Switch, its inclusion on iOS would be a welcome addition.

Razer Kishi Ultra Price Point – Value Proposition

For most users, a wireless PS5 or Xbox controller offers a superior and cheaper iOS gaming experience. However, if a telescopic, phone-attaching controller is preferred, the Razer Kishi Ultra's $150 price point surpasses the typical $99.99 cost of competitors. Is the premium justified? If the current pricing of the Razer Kishi and Backbone One is acceptable, the enhanced comfort makes the extra cost worthwhile. However, the absence of haptics on iOS diminishes the overall experience compared to Android's fully featured functionality.

Long-term joystick drift remains a potential concern.

Razer Kishi Ultra – 2024's Best Mobile Controller?

Compared to Razer's previous controllers (reviewed separately), the transition to the full-size Kishi Ultra has been notable. Similar to the Hori Split Pad Pro for Switch, I find myself desiring both a full-size and a more compact iPhone controller.

The Razer Kishi Ultra is undeniably the most comfortable mobile controller I've used, but its portability is a concern. Transporting it safely without its large box is a challenge. It's unlikely to replace my Kishi or Backbone One for travel, making it primarily a home-use device.

The absence of hall-effect analog sticks at this price point is disappointing. While I haven't experienced drift yet, it's a factor to consider.

Having reviewed Backbone One and Razer Kishi models, I'm keen to explore the GameSir lineup in the future.

Razer Kishi Ultra 2 Wishlist

For a future iteration, hall-effect analog sticks are a priority. Smoother edges around features like the passthrough charging port would enhance the design. While appreciating the L4/R4 buttons, I prefer bottom-mounted paddles for better ergonomics. Adding L5/R5 paddles with remapping in the Razer Nexus app would be a welcome addition. Finally, a carrying case would significantly improve the overall package. While not as expensive as high-end console controllers, a protective case would be a worthwhile inclusion.

Razer Kishi Ultra Review Summary

If you prefer the feel of traditional PS5 or Xbox controllers over the compact designs common in mobile controllers, the Razer Kishi Ultra's comfortable grip, excellent d-pad, and face buttons will appeal. The lack of full iOS feature support is a drawback, but it's a significant addition to the mobile controller market. Future improvements, including a carrying case, would further enhance its appeal.
