Some Users Plagued by Incorrect 'iPhone Storage Almost Full' Alert After Updating to iOS 15

Just two days after Apple released iOS 15 and iPadOS 15 to the public, a new wave of user reports from social media are already pointing to some widespread bugs, this time pertaining to reported storage on a device.

iphone storage almost full
A flood of users has taken to Twitter over the last 24-48 hours to share their experience that after updating to iOS 15, they see an "iPhone Storage Almost Full" warning inside of Settings, despite their ‌iPhone‌ having a sufficient amount of storage left. Apple Support's Twitter account is riddled with users reporting the bug.

Annoyingly, the warning inside of Settings can't be dismissed, and tapping on it only takes users to the ‌iPhone‌ Storage page within Settings, where they're reminded that their device, in the majority of cases, still has an adequate amount of storage left. A post on Apple Support's Community Forums, which has racked up over 900 views at the time of writing in just over 13 hours, also includes users reporting the bug.

The warning, however, is not the only storage-related bug that's irking some users. Other reports on Twitter indicate that iOS 15 has resulted in a bug in which the amount of available storage on a device is sometimes shown to be more than the device's capacity. In other cases, an iOS 15 bug results in the wrong tabulation for how much storage a user's content is taking up.

In all cases, Apple Support is advising users to restart their devices, but that does little to address the problem. Some of the bugs experienced by users appeared during the beta testing period for iOS 15 over the summer, which is meant to fix as many bugs and issues as possible before the update becomes widely available.

This week, Apple began testing iOS and iPadOS 15.1; however, given the widespread nature of these bugs, Apple may decide to release iOS 15.0.1 to address the storage bug and other improvements and security enchantments. We've reached out to Apple for comment.

I guess they gave me some of their storage. I’m still trying to figure out my available storage compared to the actual storage size…

This is the first time I didn't bother upgrading to a new version of iOS as soon as it was available. I turned off auto update when Apple announced CSAM and didn't bother turning it back on.

I’m still annoyed by the Other data use. Depending on device, sometimes it occupies a crazy amount.
