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 such as customizable analog stick deadzones. Since its release, the Razer Kishi Ultra has proven its compatibility extends beyond smartphones. While it's currently the priciest mobile controller on the market, its feature set justifies the cost. Having extensively used 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 did for the Nintendo Switch, significantly altered my perspective.

Razer Kishi Ultra – Package Contents

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

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

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

Unlike many mobile controllers (especially telescopic ones) that primarily support iPhones and Android devices, the Razer Kishi Ultra also accommodates tablets such as the iPad Mini 6th generation. Recent telescopic controllers have incorporated Bluetooth, but the Razer Kishi Ultra's USB-C connectivity appears to offer 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 it on 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 providing decent rumble in titles like Bakeru.

Razer Kishi Ultra Buttons, D-pad, and Triggers

Before delving into new features, let's assess the controller's feel and performance. Initial concerns about the d-pad proved unfounded; it performed exceptionally well in games like Garou: Mark of the Wolves ACA NeoGeo, Hades, and Hitman Blood Money Reprisal. The shoulder buttons and triggers function flawlessly, mirroring the quality of 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.

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. Personally, I'm not a fan of Chroma lighting on controllers, and, similar to the Razer Kitsune, I would have preferred dynamic lighting synchronized with on-screen gameplay.

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 offers a full-size feel, akin to holding a high-quality console controller. This might not appeal to those seeking a compact solution, but 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 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 the 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 many, a PS5 or Xbox controller offers a superior and more affordable wireless solution for iOS. However, if you prefer a telescopic controller that attaches directly to your phone, the Razer Kishi Ultra's $150 price point is significantly higher than the $99.99 price point of competing options. 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 absence 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 earlier, more compact controllers, the shift to this full-size design is notable. Similar to the Hori Split Pad Pro, I find myself preferring both full-size and more compact controllers for my iPhone.

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

The lack of hall-effect analog sticks at this price point is a missed opportunity. I've experienced drift issues with various controllers, and while the Razer Kishi Ultra hasn't exhibited this yet, it's a potential long-term concern.

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

Razer Kishi Ultra 2 Wishlist

For a future iteration, besides hall-effect sticks, I'd suggest smoothing out some of the sharper edges, particularly around the passthrough charging port. While appreciating the L4 and R4 buttons, I prefer bottom-mounted paddles for better ergonomics. Adding these as options (perhaps L5 and R5 with remapping) would enhance the premium feel. Finally, including a carrying case would significantly improve the overall package.

Razer Kishi Ultra Review

If you're accustomed to full-size controllers like those found on PS5 or Xbox Series consoles and prefer a more substantial feel over compact mobile controllers, the Razer Kishi Ultra is ideal. Its comfortable grip, excellent d-pad, and face buttons make it a standout. The limited iOS feature support is a drawback, but it's a significant addition to the mobile controller market. The addition of a carrying case would further enhance its appeal.
