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

TouchArcade Rating: This April, the Razer Nexus (Free) app received an update adding 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 just smartphones. While arguably 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, much like the Hori Split Pad Pro's impact on the Nintendo Switch, significantly altered my perspective.

Razer Kishi Ultra – Package Contents

The Razer Kishi Ultra's packaging contained the controller, several sets of rubber cushions (for different devices), stickers, and an instruction manual. Given its $149.99 price tag, the absence of a carrying case or pouch was a slight disappointment. However, the box and controller packaging maintained Razer's usual high-quality standards.

The included rubber cushions are paired and labeled for iPhone (Pair A), iPad Mini 6th generation (Pair B), and Android (Pair C). These are unnecessary if using a protective case.

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

Unlike many mobile controllers, particularly telescopic ones, which primarily support iPhones and Android devices, the Razer Kishi Ultra also accommodates tablets like the iPad Mini 6th generation. While some recent telescopic controllers offer Bluetooth connectivity, the Razer Kishi Ultra's USB-C connection boasts superior compatibility. For this review, I tested it with my iPhone 15 Pro, iPhone 14 Plus, and wired to my iPad Pro. Although I didn't test Android or Windows compatibility directly, I did try it wired with my Steam Deck. It registered as a generic Xbox gamepad but functioned flawlessly in games like NBA 2K25 and Bakeru (demonstrating decent rumble support).

Razer Kishi Ultra Buttons, D-pad, and Triggers

Before delving into new features, let's assess the controller's feel and performance. My initial concerns about the d-pad proved unfounded; it performed admirably in games such as Garou: Mark of the Wolves ACA NeoGeo, Hades, and Hitman Blood Money Reprisal. The shoulder buttons and triggers maintained the high standard set by previous Razer controllers. The analog sticks offered a comfortable, smooth experience, while the face buttons, despite having more travel than anticipated, remained responsive.

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

Razer Kishi Ultra – New Features

The Razer Kishi Ultra's primary appeal lies in its full-size form factor. Unlike the more 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 users 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 on iOS platforms, such as Genshin Impact.

Beyond these new features, the Razer Kishi Ultra includes a 3.5mm headphone jack, 15W passthrough charging, and L4 and R4 shoulder buttons.

Razer Kishi Ultra Features Missing on iOS – Haptics and Virtual Controller Mode

Haptics and virtual controller mode are currently exclusive to Android (and Windows for haptics). While I'm less concerned about the virtual controller mode, the absence of haptics on iOS is a significant drawback. Given my appreciation for haptic feedback on the PS5 and HD Rumble on the Switch, the lack of similar functionality on iOS is disappointing.

Razer Kishi Ultra Price Point – Is It Worth It?

For most users, a wireless PS5 or Xbox controller offers a superior and more affordable gaming experience on iOS. However, if a telescopic, phone-attaching controller is preferred, the Razer Kishi Ultra's $150 price point significantly surpasses the $99.99 price point of popular alternatives. Is the extra cost justified? For those content with the Razer Kishi or Backbone One, the enhanced comfort is worth the premium. 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 my experience with previous Razer controllers, the transition to the full-size Kishi Ultra has been notable. Similar to the Hori Split Pad Pro, I find myself preferring both a full-size and a more compact controller for my iPhone.

The Razer Kishi Ultra offers unparalleled comfort, but its bulkiness makes it less travel-friendly. Its size raises concerns about its safety in my bag without its original packaging. It's unlikely to replace my Kishi or Backbone One for travel, but it's my go-to controller for home use.

The absence of hall-effect analog sticks at this price point is a missed opportunity. While I haven't experienced drift 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 iteration, I'd suggest incorporating hall-effect analog sticks and smoothing out some of the sharper edges, such as the passthrough charging port. While appreciating the L4 and R4 buttons, I prefer bottom-mounted paddles for a more natural feel. Adding L5 and R5 paddles with remapping capabilities in the Razer Nexus app would be a welcome addition. Finally, including a carrying case would elevate the overall package.

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 responsive face buttons are highlights. The lack of full feature support on iOS is a letdown, but overall, it's a significant addition to the mobile gaming market. I hope Razer addresses the iOS limitations and includes a carrying case in future versions.
