Zenless Zone Zero setup: parry frames, not frame rate graphs
Official ZZZ requirements for PC, iOS and Android, why the 61 GB decompression step catches people out, and the three purchases that fix real problems.

TL;DR
A 7th-gen i5, 8 GB of RAM and a GTX 970 clear HoYoverse’s PC minimum, which is a low bar for 2026 — the requirement that trips people up is 122 GB free before you install, because the client decompresses alongside itself. On mobile, nothing you can buy makes the chip faster; a cooler is the only thing that keeps it fast.

Two things to notice.
The storage requirement is a two-step trap. 61 GB is the finished install. The installer needs roughly the same again while it unpacks, which is why HoYoverse’s guidance lands at about 122 GB free before you begin. People with 70 GB free start the download, wait an hour, and fail at the last step. This is the most common installation complaint for this game and it is entirely avoidable.
The Android RAM floor is 8 GB. That is high for a mobile gacha and it is the row that excludes most older mid-range handsets. The chipset list — Snapdragon 855 era — sounds forgiving; the memory requirement is not.
What the minimum spec actually gives you: a stable game at low settings and a capped frame rate. In ZZZ specifically that is a bigger compromise than it sounds, because the combat system is built on perfect dodges and defensive assists with tight windows. A locked 30 is playable. An unstable 45 is worse than either 30 or 60.
Apple’s listing for ZZZ, published by Cognosphere Pte. Ltd., gives the installer at around 3.1 GB and iOS 14.0 or later — we have that figure in verify because we read it from a search index rather than loading the store page directly.
The real bottleneck
ZZZ is the one gacha in this group where frame-time consistency is a mechanic, and the thing that destroys frame-time consistency on a phone is heat.
Your defensive assist and perfect dodge windows are measured in frames. When the phone throttles — and it will, somewhere between minute eight and minute fifteen of sustained combat — the frame rate does not gently decline, it becomes uneven. You stop landing parries you used to land and you assume you got worse. You did not; the device did.
This leads to a conclusion most hardware articles will not write: a faster phone does not solve this. A newer SoC runs hotter in the same thin chassis and throttles from a higher starting point. The useful interventions are, in order of cost:
- Take the case off. Free. Do it before anything else.
- Cap the frame rate at a number you can hold for a whole session. Free.
- Stop charging while you play. Free, and it is the second-largest heat source in the device.
- Active cooling. About the price of a monthly battle pass, and the only purchase that addresses the mechanism rather than the symptom.
On PC the bottleneck is boring: it is the 122 GB of free space you need once, and after that the game is comfortably within a 2016-era GPU’s reach. ZZZ does not need a graphics card upgrade. It needs an afternoon of deleting things.
What’s worth buying
Three products, in descending order of how much they matter.
The cooler addresses thermal throttling on mobile, which is the actual mechanism behind “the game feels worse after ten minutes.” The 8BitDo Ultimate 2C is a thirty-dollar PC pad for a game designed around a controller layout. The Razer Kishi V3 is the mobile equivalent and costs three times as much — it is in this list for players who play ZZZ primarily on a phone and push Shiyu Defense, not for everyone.
ZZZ is unusual among HoYoverse games in supporting controllers on Android as well as iOS, with the DualShock 4, DualSense, Xbox One and Xbox Series pads as the officially named models. If you own any of those, plug it in and skip both controller recommendations. That is the correct advice and it costs nothing.
Read the cons on each card. The Kishi occupies your charging port, the 8BitDo uses ordinary sticks that will drift, and the cooler needs its own cable and makes noise. None of these is a free win.
Recommended settings
In order. Stop when the frame time is flat.
- Render / resolution scale. First lever, every time. 0.9 then 0.8 before you touch anything else.
- Frame rate cap. Choose the number you can hold for the whole session. In a parry game, 30 locked beats 60 that wobbles. This is the single most important setting in ZZZ and the one most people get wrong.
- Shadows. Expensive and invisible during a Chain Attack.
- Bloom and post-processing. ZZZ leans hard on post effects. Dropping them one step is a real frame-time saving and barely changes the look.
- Character detail / crowd density in Sixth Street. The hub areas, not the combat arenas, are where ZZZ stutters on weaker devices. Lower this and combat is unaffected.
- Anti-aliasing: low, not off. The cel-shaded outlines alias badly without it.
Leave texture quality alone unless you are at the 8 GB RAM floor.
What’s a waste of money
The purchases players make for this game and regret.
A graphics card upgrade. The recommended GPU is a GTX 1660. If your card is newer than that and ZZZ stutters, the problem is your CPU’s single-thread performance, a background app, or a drive that is nearly full. A new GPU will change nothing.
A Gen5 SSD. You need capacity, not sequential throughput. A mainstream PCIe 4.0 drive — or even a SATA SSD — clears the loading problem entirely.
A gaming phone bought for ZZZ. The vapour chamber is treating the right problem, but you are paying hundreds of dollars for cooling you can buy as an accessory, plus a 165 Hz screen the game will never use.
A high-polling-rate mouse. ZZZ is a controller-first action game. An 8 kHz mouse is pure waste here.
Shoulder-trigger clip-on buttons. Those plastic capacitive triggers sold for shooters do nothing in a game with no aim-and-fire input. They also block airflow at the exact corner of the phone that gets hottest.
A passive cooling case. Metal and graphene plates collect heat and then have nowhere to send it. Removing the case does more, for nothing.
Charging at 65 W while you play. This is the most common self-inflicted performance problem in mobile gacha. You are heating the device on purpose while asking it to sustain peak clocks.
FAQ
Why does my ZZZ install fail at 90 %? Almost always free space. The client needs roughly 61 GB for the finished install and about the same again temporarily while it decompresses, so plan for about 122 GB free. Clear the space before you start rather than during.
Is 8 GB of RAM enough on PC? It is both the minimum and, per the official table, the recommended figure — which is unusual and is one of the rows we have flagged for re-checking. In practice 8 GB works, and 16 GB is the cheap sensible upgrade if you keep a browser open.
Does ZZZ support controllers on Android? Yes, and that genuinely sets it apart from HoYoverse’s other titles. The named models come from the DualShock 4, DualSense, Xbox One and Xbox Series families. Support is not enabled automatically on mobile — you turn it on in the input settings.
Will a phone cooler give me more FPS? No. It stops you losing the FPS you already have. That distinction matters: your phone hits its peak frame rate in the first minute of a session regardless. A cooler is about minute fifteen. We are not publishing a temperature or frame-rate figure because we have not measured one, and inventing bench numbers is how hardware coverage stops being worth reading.
