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 and more. Since its release, the Kishi Ultra has proven its compatibility extends beyond just phones, making it, to my knowledge, the priciest mobile controller available. However, it offers unexpected features for various 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 changed my perspective, much like the Hori Split Pad Pro did for the Nintendo Switch years ago.

Razer Kishi Ultra – Package Contents

The Razer Kishi Ultra package includes the controller, several sets of rubber cushions (for different devices), stickers, and an instruction manual. Given its $149.99 price tag, I anticipated a carrying case or at least a protective pouch. However, the box and controller packaging are, as expected from Razer, high-quality.

The 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 only 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 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 to 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, but functioned flawlessly while playing NBA 2K25 on the Steam Deck. It also supports decent rumble, as demonstrated 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 reservations about the d-pad, but it performed admirably in games like Garou: Mark of the Wolves ACA NeoGeo, and newer titles such as Hades and Hitman Blood Money Reprisal. Beyond the d-pad, the shoulder buttons and triggers function as well as those on Razer's older controllers. The analog sticks are comfortable and smooth, while the face buttons offer a satisfying click, although with more travel than expected 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 use. I'm not a fan of Chroma lighting on controllers, and similar to the Razer Kitsune, I would have preferred if the lights could dynamically reflect on-screen gameplay.

Razer Kishi Ultra – New Features

The Razer Kishi Ultra's main appeal is its full-size form factor. Unlike Razer's previous offerings or the Backbone One, which feel compact, the Kishi Ultra is full-sized, feeling 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, as some notable titles (like Genshin Impact) lack controller support on mobile outside of iOS.

Additionally, the Razer Kishi Ultra features 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 exclusive to Android (and Windows for haptics) and unavailable on iOS. While I'm not overly concerned about virtual controller mode, I hope Razer will find a way to enable haptics on iOS. I appreciate haptic feedback on the PS5 and HD Rumble on the Switch, and a similar feature on iOS would be a welcome addition.

Razer Kishi Ultra Price Point – Is It Worth It?

I believe most users would be better off using a PS5 or Xbox controller wirelessly on iOS – a superior and more affordable option. If you prefer a telescopic controller that attaches to your phone, popular alternatives are priced around $99.99, making the $150 Razer Kishi Ultra a premium option. Is it worth the extra cost? If you're satisfied with the current pricing of the Razer Kishi and Backbone One, the added comfort justifies the higher price. However, the lack of haptics on iOS diminishes the overall experience compared to Android, where you get the full feature set.

The long-term durability of the joysticks remains to be seen; joystick drift is a concern with many controllers.

Razer Kishi Ultra – The Best Mobile Controller in 2024?

If you haven't read my review of Razer's older controller, you can find it [link to previous review]. Transitioning from the compact form factor I've grown accustomed to with Razer and Backbone products to this larger controller has been interesting. Similar to the Hori Split Pad Pro for the Nintendo 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 ever used, but its portability is a concern. I worry about its safety in my bag unless I transport it in its original box. It's unlikely to replace my regular Kishi or Backbone One for travel; I'll primarily use it at home.

At this price point, I had hoped for hall-effect analog sticks. I've experienced joystick drift with multiple controllers, and while it hasn't occurred with the Razer Kishi Ultra (or the original Kishi) yet, it's a potential long-term concern.

Having reviewed Backbone One and Razer Kishi models, I'm keen to try the GameSir lineup, which seems promising.

Razer Kishi Ultra 2 Wishlist

Regarding potential improvements for a future Razer Kishi Ultra, besides hall-effect sticks, I'd like some of the sharper edges (like the passthrough charging port) to be smoother. While I appreciate the L4 and R4 buttons, I prefer bottom-mounted paddles for a more natural feel. Offering these as options, given the premium price, would be beneficial. Perhaps even L5 and R5 paddles with remapping in the Razer Nexus app. Finally, a carrying case would be a welcome addition, mirroring the inclusion of hard cases with high-end console controllers. While not as expensive as a DualSense Edge or Victrix Pro BFG, a case would enhance the package without significantly increasing the cost.

Razer Kishi Ultra Review

If you're accustomed to traditional PS5 or Xbox Series controllers (or any full-sized controller) and find the compact buttons and sticks of typical mobile controllers unsatisfactory, the Razer Kishi Ultra is ideal. Its comfortable grip, excellent d-pad, and face buttons make it stand out. The lack of full feature support on iOS is disappointing, but it's a significant addition to the mobile controller market. I hope Razer continues to improve it and includes a carrying case for better portability.

Razer Kishi Ultra review score: 4.5/5
