Razer Kishi Ultra: Best Mobile Gaming Controller of 2024?

TouchArcade Rating: 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. Since its release, the Kishi Ultra has proven its versatility beyond just smartphone compatibility. While undeniably the priciest mobile controller on the market, 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 proved a game-changer, much like the Hori Split Pad Pro did for the Nintendo Switch.

Razer Kishi Ultra – Package Contents

The Razer Kishi Ultra's packaging included 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: Pair A (iPhone), Pair B (iPad Mini 6th generation), and Pair C (Android). These cushions are unnecessary if using a phone case.

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

Unlike most telescopic mobile controllers (which typically 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 offer Bluetooth connectivity, the Kishi Ultra's USB-C connection 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 compatibility, I did try it wired on my Steam Deck. It was recognized as a generic Xbox gamepad, functioning well in games like NBA 2K25 and providing decent rumble in titles like Bakeru.

Razer Kishi Ultra Buttons, D-pad, and Triggers

Before discussing new features, let's assess the controller's feel and performance. I initially harbored concerns about the d-pad, but it performed exceptionally well in games like Garou: Mark of the Wolves ACA NeoGeo, Hades, and Hitman Blood Money Reprisal. Beyond the d-pad, the shoulder buttons and triggers function flawlessly, mirroring Razer's previous controllers. The analog sticks are comfortable and smooth, while the face buttons, though clicky, have more travel than expected compared to the original Razer Kishi.

After extensive use, including several hours-long gaming sessions (like Zenless Zone Zero while charging via passthrough), I have no complaints regarding the d-pad, buttons, or triggers.

The textured finish, while not rubbery, provides excellent 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 dynamic lighting that synced with on-screen gameplay.

Razer Kishi Ultra – New Features

The Razer Kishi Ultra's main selling point is 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, akin to holding a phone within a high-quality console controller. While this might not appeal to those seeking a compact solution, 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 on iOS, such as Genshin Impact.

Additional features include 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 exclusive to Android (and Windows for haptics) and 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 welcome.

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, for those seeking a telescopic controller that attaches directly to their phone, the Razer Kishi Ultra's $150 price point is significantly higher than the $99.99 price point of competing controllers. 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 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 this full-size design is significant. Similar to the Hori Split Pad Pro for Switch, I find myself preferring both full-size and more compact controllers for my iPhone.

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

The lack of hall-effect analog sticks at this price point is disappointing. I've experienced joystick drift with other controllers, and while the Kishi Ultra hasn't exhibited this yet, it's a potential concern.

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, hall-effect analog sticks are a priority. Smoother edges, particularly around the passthrough charging port, would improve the design. While the L4 and R4 buttons are useful, bottom-mounted paddles would be more intuitive. Adding L5 and R5 paddles with remapping capabilities in the Razer Nexus app would be a significant upgrade. Finally, including a carrying case would enhance the premium feel and protect the controller during transport.

Razer Kishi Ultra Review Summary

If you prefer the feel of full-size controllers like the PS5 or Xbox controllers, the Razer Kishi Ultra's comfortable grip, excellent d-pad, and face buttons are ideal. The limited iOS feature set is disappointing, but it's a significant addition to the mobile controller market. Future improvements, including a carrying case, would further enhance its appeal.
