Persona 5 The Phantom X File Size: Device Storage Needed

Persona 5 The Phantom X is a large game, especially on PC. Expect roughly 30–75 GB needed on computers and around 18–30 GB on mobile once all data and updates are installed.​

Approximate File Size by Platform

• PC (Steam / official client):
  • Actual install size after download: around 32–40 GB for the base game at launch.​
  • Recommended free space: 70–75 GB to handle downloads, patches, and high-res assets (Steam and official PC guides both suggest ~70 GB or more).​
• Android:
  • Core game data: about 17–18 GB installed.​
  • Official requirement: 30 GB free space recommended to account for patches, language packs, and event assets.​
• iOS:
  • Initial App Store download is a few GB (around 3–4 GB), but in-app data pushes total usage toward 15–20+ GB after resource downloads.​
  • Official requirement: 30 GB free space available, same as Android.​

Because the game streams in additional content and offers multiple language packs, the exact number on your device can vary, but planning for ~30 GB on mobile and ~70 GB free on PC keeps you safe for future updates.​
