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. This controller boasts features like customizable analog stick deadzones. Since its release, the Razer Kishi Ultra has proven its compatibility extends beyond smartphones. While the most expensive mobile controller I've encountered, 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, has changed my perspective.

Razer Kishi Ultra – Package Contents

The Razer Kishi Ultra packaging included the controller, various rubber cushions for device compatibility (iPhone, iPad Mini 6th gen, Android), stickers, and instructions. At $149.99, I anticipated a carrying case or at least a protective pouch. However, the box and controller's internal 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 are unnecessary if using a phone case.

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

Unlike many mobile controllers (especially telescopic ones) that only support iPhone and Android, the Razer Kishi Ultra also supports tablets like the iPad Mini 6th generation. While some recent telescopic controllers offer Bluetooth, this USB-C controller 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, 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 exhibiting good 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. My initial concerns about the d-pad proved unfounded; it performed excellently in games like Garou: Mark of the Wolves ACA NeoGeo, Hades, and Hitman Blood Money Reprisal. The shoulder buttons and triggers function 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 compared to the original Razer Kishi.

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 a good grip and remains comfortable even during extended use. While I'm not a fan of Chroma lighting on controllers, I would have preferred synchronized on-screen gameplay lighting, 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 compact designs of previous Razer controllers or the Backbone One, the Kishi Ultra 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 it's not designed to be one. The full-size design makes it the most comfortable mobile controller I've used.

Other 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 exclusive to Android (and Windows for haptics), absent from the iOS version. While I'm less concerned about virtual controller mode, I hope Razer addresses the lack of haptics on iOS. 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, if you prefer a telescopic controller that attaches directly to your phone, the Razer Kishi Ultra's $150 price tag is significantly higher than the $99.99 price point of popular alternatives. Is the extra cost justified? If you're satisfied with the Razer Kishi or Backbone One, the comfort upgrade is worth the price. However, the lack of haptics on iOS diminishes the overall experience compared to Android.

Long-term joystick drift remains a concern.

Razer Kishi Ultra – The Best Mobile Controller in 2024?

Compared to Razer's previous compact controllers and the Backbone One, the transition to the full-size Razer Kishi Ultra has been interesting. Similar to the Hori Split Pad Pro for Switch, I find myself wanting both a full-size and a more compact controller for my iPhone.

The Razer Kishi Ultra is the most comfortable mobile controller I've used, but its portability is a drawback. Its size makes it less ideal for travel unless carried in its original box. It's unlikely to replace my Kishi or Backbone One for travel, making it more of a home-use controller.

The absence of hall effect analog sticks at this price point is notable. I've experienced drift issues with other controllers, and while the Kishi Ultra hasn't exhibited this yet, it's a potential long-term 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, I'd prioritize hall effect analog sticks and smoother edges around features like 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 capabilities in the Razer Nexus app would be a valuable enhancement. Finally, including a carrying case would elevate the premium feel. While not as expensive as a DualSense Edge or Victrix Pro BFG, a case would be a worthwhile inclusion.

Razer Kishi Ultra Review

If you prefer the feel of full-size controllers like those found on PS5 or Xbox Series consoles and find compact mobile controllers uncomfortable, the Razer Kishi Ultra is ideal. Its comfortable grip, excellent d-pad, and face buttons are highlights. The lack of full feature support on iOS is a letdown, but it's a significant addition to the mobile controller market. I hope Razer builds upon this design, adding a carrying case for improved portability.
