Gone are the days when mobile gaming meant tapping at candy or flinging birds at pigs. Today, it’s a full-blown revolution. Picture this: You’re on a train, diving into Genshin Impact with graphics that rival your PlayStation, or battling strangers worldwide in Call of Duty: Mobile tournaments. Smartphones are now powerhouses, and cloud services like Xbox Game Pass stream console hits like Halo Infinite straight to your pocket. But let’s be honest—touchscreen controls just don’t cut it for this level of gaming. That’s where the Razer Kishi Ultra Mobile Gaming Controller steps in. After weeks of testing, I’m breaking down why this gadget might be the best thing to happen to your phone since 5G.
Design: Built Like a Tank, Feels Like a Glove
Razer’s always had a knack for making gear that looks like it belongs in a sci-fi flick, and the Kishi Ultra is no exception. But this isn’t just eye candy—it’s built to survive rage-quits and cross-country trips.
- Stretch to Fit: The telescoping bridge is pure genius. Slide it open, plop in your iPhone 15 Pro Max (case still on, thank you), and it locks in snugly. No wobble, no fuss. Smaller phones? The rubberized grips hug them tight, so you won’t fumble during a Fortnite build battle.
- No More Stick Drift: I’ve murdered three budget controllers thanks to joystick drift. Razer’s anti-drift analog sticks? Smooth as butter after 50 hours of Diablo Immortal. The buttons have a satisfying “click” that cheap knockoffs just can’t mimic.
- RGB for the Win: Yeah, RGB lighting is extra… but when your controller pulses red during a Resident Evil boss fight, you’ll feel like a hero in a movie. Customize it all through Razer’s app—because why shouldn’t your gear match your vibe?
The Real Win: Most mobile controllers make you peel off your $50 phone case. Not this one. Razer gets it—you’re not risking your Galaxy S24 Ultra’s finish for a gaming sesh.
Compatibility: Plays Nice With Everyone
Let’s cut to the chase: If it’s got a screen, the Kishi Ultra probably works with it.
- iOS or Android? Pick Your Poison: Lightning for iPhone, USB-C for Android. I tested both, and setup was laughably easy—plug in, and your phone instantly treats it like a console controller. No Bluetooth pairing nightmares.
- PC Gamers, Rejoice: Hook it to your laptop via USB-C, and suddenly you’re playing Elden Ring on Steam without lugging around a bulky Xbox pad.
- Cloud Gaming’s Best Friend: Xbox Cloud Gaming and NVIDIA GeForce Now felt like I was playing on an actual console. Forza Horizon 5 on my Pixel 7 Pro? Butter.
Pro Tip: Tired of games ignoring your controller? Minecraft and Roblox recognized the Kishi Ultra instantly. Even niche titles like Dead Cells worked flawlessly.
Performance: Zero Compromises
This is where Razer flexes. The Kishi Ultra isn’t just good—it’s console-good.
- Latency? What Latency?: Wired means no lag. At all. In PUBG Mobile, I outgunned snipers because my shots registered faster than theirs. Bluetooth controllers can’t touch this.
- Triggers That Trick Your Brain: The L2/R2 buttons have real resistance, like a DualSense controller. Playing Asphalt 9, I could feather the throttle around corners instead of just mashing buttons.
- Secret Weapon: Rear Paddles: Assign complex moves to the M1/M2 buttons. In Diablo Immortal, I mapped potions and ultimates here—no more fat-fingering spells mid-battle.
Real Talk: The D-pad is crisp, but fighting game purists might miss the “clickiness” of a PlayStation pad. Still, it’s miles better than touchscreen swipes.
Comfort: Marathon-Approved
I’m guilty of eight-hour Genshin Impact grinds. Here’s why my hands didn’t revolt:
- Grips That Don’t Quit: The textured rubber palms are like memory foam for your hands. Even when I got sweaty during a COD: Mobile ranked match, the controller stayed put.
- Lightweight, Not Cheap: At 150g, it’s lighter than your AirPods case. But the matte plastic feels premium—no creaks or flex.
- Cooling? Seriously?: Those tiny vents on the back seemed gimmicky… until I realized my phone wasn’t overheating during a Honkai: Star Rail binge. Genius.
Long-Haul Verdict: After a weekend of Elden Ring Mobile (yes, it’s a thing), my hands felt fresh. Take that, Joy-Cons.
Customization: Make It Uniquely Yours
Razer’s app isn’t just for RGB—it’s a power user’s playground.
- Remap Everything: Swapped jump and shoot buttons for Apex Legends Mobile? Done. Adjusted stick sensitivity for Sky: Children of the Light? Easy.
- Lighting That Talks to Games: Set the LEDs to flash when your Minecraft health drops. It’s silly but weirdly immersive.
- Updates That Matter: Razer pushed a firmware patch during my testing that fixed Hades Mobile compatibility. No more praying to the update gods.
Hot Take: The app’s a bit overkill for casuals, but tinkerers will love it.

Who’s It For? (And Who Should Skip It)
Buy It If:
- You’re tired of losing PUBG matches to laggy Bluetooth junk.
- Your phone never leaves its OtterBox case.
- You want one controller for mobile, PC, and cloud gaming.
Skip It If:
- You only play Candy Crush on the toilet.

Final Word
The Razer Kishi Ultra isn’t cheap, but it’s the first mobile controller that made me forget I wasn’t holding an Xbox pad. From the rock-solid build to the stupidly responsive buttons, it’s clear Razer built this for gamers who refuse to settle. If you’re serious about mobile play—whether it’s climbing Genshin Impact leaderboards or grinding XDefiant on GeForce Now—this thing’s worth every penny. Just don’t blame me when your phone battery dies mid-boss fight.
