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

TouchArcade Rating: Back in 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 its compatibility extends beyond just smartphones. While it's currently the priciest mobile controller on the market, its feature set justifies the cost for many users. 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 surprisingly changed my perspective, much like the Hori Split Pad Pro did for the Nintendo Switch.

Razer Kishi Ultra – Package Contents

The Razer Kishi Ultra package contains the controller, various rubber cushions for different devices, stickers, and an instruction manual. Given its $149.99 price tag, the absence of a carrying case or pouch is a noticeable omission. However, the box and controller packaging maintain Razer's usual high-quality standards.

The included rubber cushions are paired and clearly 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 – iPhones, Cases, Android, and iPad Mini

Unlike many mobile controllers, especially telescopic ones, which primarily support iPhones and Android devices, the Razer Kishi Ultra also supports tablets like the iPad Mini 6th generation. While some recent telescopic controllers offer Bluetooth connectivity, the Razer Kishi Ultra's USB-C connection seems to offer superior compatibility. For this review, I tested the controller on my iPhone 15 Pro, iPhone 14 Plus, and wired on my iPad Pro. Although I didn't test it on Android or Windows devices, I did try it wired on my Steam Deck. It was recognized as a generic Xbox gamepad but functioned perfectly while playing NBA 2K25 and exhibited decent rumble in games like Bakeru.

Razer Kishi Ultra Buttons, D-pad, and Triggers

Before discussing the new features, let's assess the controller's feel and performance. I initially had 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. The shoulder buttons and triggers function as smoothly as those on Razer's previous controllers. The analog sticks are comfortable and responsive, 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 (playing Zenless Zone Zero while charging my phone via passthrough charging), 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 not a fan of Chroma lighting on controllers, I would have preferred a feature that synchronizes the lights 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 Razer's previous models or the Backbone One, it's a full-size controller, making it feel like you're holding your phone within a high-quality console controller. This might not appeal to those seeking a compact solution, but that's not its intended purpose. The full-size design makes it the most comfortable mobile controller I've used.

Other notable features include Chroma customization via the app, haptics (for 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.

Additionally, the Razer Kishi Ultra includes a 3.5mm headphone jack, passthrough charging (15W), 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) 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 a welcome addition.

Razer Kishi Ultra Price Point – Is It Worth It?

For most users, a 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 $99.99 price point of popular alternatives. Is the extra cost justified? If you're satisfied with the Razer Kishi or Backbone One, the upgrade is worthwhile for the enhanced comfort. However, the lack of haptics on iOS diminishes the overall experience compared to Android.

Long-term joystick drift remains a concern, although it hasn't been observed yet on this or the original Razer Kishi.

Razer Kishi Ultra – The Best Mobile Controller in 2024?

The transition from the compact form factor of previous Razer and Backbone controllers 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 undoubtedly the most comfortable mobile controller I've used, but its larger size makes it less travel-friendly. I'm concerned about its portability unless carried in its original box. It's unlikely to replace my Kishi or Backbone One for travel, but it's my go-to controller for home use.

At this price point, hall-effect analog sticks would have been a welcome addition. I've experienced drift issues with other controllers, and while it hasn't occurred yet with the Razer Kishi Ultra, it's a potential long-term concern.

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 of the Razer Kishi Ultra, I'd suggest 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 these as options, potentially with L5 and R5 paddles and remapping capabilities within the Razer Nexus app, would enhance the premium feel. Finally, including a carrying case would significantly improve the overall package.

Razer Kishi Ultra Review

If you prefer the feel of full-sized controllers like those found on PS5 or Xbox Series consoles and find the compact controls of typical mobile controllers less satisfying, the Razer Kishi Ultra is ideal. Its comfortable grip, excellent d-pad, and face buttons make it a standout. The lack of full feature parity on iOS is disappointing, but it's a significant addition to the mobile controller market. I hope Razer continues to improve upon this design and includes a carrying case in future versions.
