# Why does Google Drive take up so much space on my iPhone? — Adinand Email Cleaner Last reviewed: September 24, 2026. HTML version: https://adinandemail.com/answers/google-drive-take-up-so-much-space-on-iphone **The number in iPhone Storage is what the Google Drive app keeps on the phone — files saved for offline use, previews and other app data — not the size of your Drive.** Your Drive lives in your Google account. The two are separate stores with separate limits, and the fix for one does nothing for the other. [Which one is full?](https://adinandemail.com/answers/phone-or-google-storage) is worth answering first. ## Read the number properly

Apple's steps: open Settings, tap General, tap iPhone Storage, and "Tap an app's name for more information about its storage." On that screen Apple offers two actions, offloading the app and deleting it. Apple also warns that "Cached data and temporary data might not count as usage", so the figure is not necessarily everything the app holds ([*How to check the storage on your iPhone and iPad*](https://support.apple.com/en-us/108429), read 24 September 2026).

If Google Drive sits near the top of that list at a few gigabytes, the steps below are for you.

## What the Drive app keeps on the phone

The one thing Google documents is offline copies. In the iPhone app you turn a file's offline copy on with More, then **Available offline**, and you find everything you have saved that way under Menu, **Offline** ([*Use Google Drive files offline — iPhone & iPad*](https://support.google.com/drive/answer/2375012?co=GENIE.Platform%3DiOS), read 24 September 2026). That Offline list is the first place to look: a few videos or long PDFs marked months ago for a flight can account for a lot of phone space.

What Google does not document is anything else. The iPhone help pages we read describe no "clear cache" control in the Drive app and say nothing about how much the app stores on its own for previews or recent files. We are not going to describe a menu Google has not described.

## Shrinking it, in the order we would try
  1. **Open Menu, Offline, and switch off Available offline** on anything you no longer need on the plane or the train. The file stays in Drive; only the phone copy goes.
  2. **Check iPhone Storage again.** Apple says that "When your device is low on storage, it frees up space by removing items that you can download again or aren't needed, like unused apps and temporary files", so some of this may clear on its own.
  3. **If the app is still large, delete it and install it again.** Apple: deleting "removes the app and its related data". Offloading will not help here, because offloading "keeps its documents and data". Before deleting, open the app and make sure nothing is still uploading — Google's page does not say what happens to an upload interrupted this way, and we would not find out with a file that matters.

Google counts "Files in Google Drive" against your Google account's storage ([*How your Google storage works*](https://support.google.com/drive/answer/9312312), read 24 September 2026), which is to say they live in the account, not in the app. Our expectation is that after a reinstall and sign-in they are listed as before, and you only mark offline again the few you really want without signal.

## The button that frees the wrong space

Deleting a file inside the Drive app — More, then Remove — does not free phone space in any useful sense. It moves the file to Drive's Trash in your Google account, where "Files in your Trash still count towards your storage until they are permanently deleted", and "Files you move to the Trash are deleted forever after 30 days" ([*Delete files in Google Drive — iPhone & iPad*](https://support.google.com/drive/answer/2375102?co=GENIE.Platform%3DiOS), read 24 September 2026). The same page notes that "Anyone you shared your file with can continue to access it until the file is permanently deleted".

So Remove is a way to delete the file from Drive everywhere, on a timer. It is the right step for a file you want gone and the wrong one for a phone that is short of space, which is exactly the situation in which people press it.
