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 and more. Since its release, the Razer Kishi Ultra has proven itself a top-tier mobile gaming controller, albeit the priciest I've encountered. Despite already owning and frequently using the Razer Kishi and Backbone One (including their USB-C iterations), the Kishi Ultra's features significantly impressed me, much like the Hori Split Pad Pro did for the Nintendo Switch.

Razer Kishi Ultra – Package Contents

The Razer Kishi Ultra's packaging includes the controller, several sets of rubber cushions (for various devices), stickers, and an instruction manual. Given its $149.99 price tag, the omission of a carrying case or pouch is somewhat disappointing. However, the box and controller casing maintain Razer's usual high-quality construction.

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 you use a phone case.

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

Unlike many mobile controllers (especially telescopic ones) that only 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 Kishi Ultra's USB-C connection appears to offer superior compatibility. For this review, I tested it 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 to my Steam Deck. It was recognized as a generic Xbox gamepad, functioning well in games like NBA 2K25 and providing satisfying rumble feedback in titles such as Bakeru.

Razer Kishi Ultra Buttons, D-pad, and Triggers

Before delving into its unique features, let's assess the controller's core functionality. My initial concerns about the d-pad proved unfounded; it performed admirably in games ranging from Garou: Mark of the Wolves ACA NeoGeo to modern titles like Hades and Hitman Blood Money Reprisal. The shoulder buttons and triggers maintain the high standard set by previous Razer controllers. The analog sticks are comfortable and smooth, while the face buttons, though clicky, have more travel than anticipated compared to the original Razer Kishi.

After extensive use, including several hours-long gaming sessions (like playing Zenless Zone Zero while charging my phone 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 extended play sessions. While I'm generally indifferent to 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 most significant advantage is its full-size form factor. Unlike the more compact designs of previous Razer controllers or the Backbone One, the Kishi Ultra feels like a full-sized console controller with the phone integrated into the center. While this may 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 ever used.

Additional features include Chroma customization via the app, haptics (Android and Windows), and virtual controller mode (Android only). The virtual controller mode is particularly useful 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, 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 PS5 and HD Rumble on Switch, this omission is disappointing.

Razer Kishi Ultra Price Point – Is It Worth It?

For many, a wireless PS5 or Xbox controller offers a superior and more affordable wireless gaming experience on iOS. However, if you prefer a telescopic controller that directly attaches to your phone, the Razer Kishi Ultra's $150 price point is significantly higher than the typical $99.99 price of competing controllers. Is the extra cost justified? If you're content with the pricing of the Razer Kishi and Backbone One, the enhanced 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 (specifically, the potential for drift) remains to be seen.

Razer Kishi Ultra – The Best Mobile Controller in 2024?

Compared to Razer's earlier, more compact controllers, the Kishi Ultra's full-size design is a significant change. Similar to the Hori Split Pad Pro for Switch, I find myself appreciating both full-size and more compact options.

The Razer Kishi Ultra offers unparalleled comfort, but its bulkier size makes it less travel-friendly. I'm concerned about its portability 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, the absence of hall-effect analog sticks is noteworthy. I've experienced joystick drift with various controllers, and while the Kishi Ultra hasn't exhibited this yet, 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 iteration, I'd suggest hall-effect analog sticks and smoother edges around features like the passthrough charging port. While the L4 and R4 buttons are appreciated, I prefer bottom-mounted paddles for better ergonomics. Adding L5 and R5 paddles with remapping capabilities in the Razer Nexus app would be a welcome enhancement. Finally, including a carrying case would significantly improve the overall package.

Razer Kishi Ultra Review Summary

If you prefer the feel of full-sized controllers like those found on PS5 or Xbox and find compact mobile controllers less comfortable, the Razer Kishi Ultra is an excellent choice. Its comfortable grip, responsive d-pad, and satisfying face buttons are highlights. The lack of full feature parity on iOS is a letdown, but overall, it's a significant addition to the mobile gaming controller market. A carrying case would further enhance its appeal.
