"Last night I deleted over 1,000 pictures and a few apps from my phone because the storage was getting full. The amount used was around 12GB before I began deleting things. Afterward, it was down to around 11GB and seemed to acknowledge the fact that I deleted things. When I woke up this morning, I had an alert that 0 bytes available on iPhone. My used storage is back up to 12.1GB and I have 0 bytes of available storage. I tried to delete a few apps to see if the storage amount would change, and it did not."



Dealing with "0 bytes available on iPhone" alerts is really annoying because this issue leaves users confused about the capacity of their device, even though there is nothing on the device but the available storage capacity is 0. This problem has severely affected the performance of your iPhone, and now you are unable to download apps and other new content. To restore the best functionality of your iPhone, we now take you through the root causes of this issue and explore possible solutions.

Part 1: iPhone Says 0 Bytes Available

What Does 0 Bytes Mean on iPhone

When you see "0 bytes" on your iPhone, it means there is no free storage space left on your device. At this point, you can no longer use the features of your iPhone. For example, you can't download new apps, take photos, or even receive messages. You can free up space by deleting unnecessary files or applications.

However, the strange thing is, iPhone says not enough storage but there is! Even though the iPhone displays 0 bytes available, it's not always the case. Some users report that after deleting files from their device, they don't see any change in storage space. If this happens, we need to understand the reason first.

Why Does My iPhone Say 0 Bytes?

In some cases, it does mean that your iPhone is full of data and there is not a bit of free space left. In this case, cleaning your iPhone can free up space. However, in most cases, this is probably just a bug happening on your iPhone, and this error could stem from:

  • A bug called phantom usage
  • Virus attack
  • system breakdown
  • ...

When your iPhone is showing 0 free bytes due to the reasons mentioned above or similar reasons, trying to free up space on your iPhone is in vain. For this situation, next, we provide three effective solutions to resolve 0 bytes available error on iPhone without data loss.

Part 2: How to Fix 0 Bytes Available on iPhone?

When iPhone says 0 bytes available, you can try the following fixes to regain access to iPhone storage space. In order to avoid the risk of data loss during the repair process, we recommend that you use iTunes, iCloud or third-party backup software MobiKin Assistant for iOS to back up your iPhone in advance.

Fix 1: Force Restart iPhone

A force restart can clear your iPhone's RAM without deleting any data, which can often resolve minor software glitches such as incorrect data storage.

To perform a force restart:

  • For iPhone 8 and later models: Press and quickly release the Volume Up button, then press and quickly release the Volume Down button. Finally, press and hold the Side button until the Apple logo appears.
  • For iPhone 7 and 7 Plus: Press and hold both the Volume Down and Sleep/Wake (Side) buttons simultaneously until the Apple logo appears.
  • For iPhone 6s and earlier models: Press and hold both the Home and Sleep/Wake (Top) buttons simultaneously until the Apple logo appears.

Fix 2: Run Antivirus Software

As mentioned above, malicious software could be a cause of storage issues. If the 0-byte error is caused by a virus attack, running antivirus software on your iPhone can scan for any malicious software and remove it. However, please note that due to iOS's robust security measures, access to and functionality of third-party antivirus applications may be restricted.

Fix 3: Factory Reset iPhone

Performing a factory reset may resolve storage errors caused by complex software issues, but doing so will delete all content and settings from your iPhone, so you must back up the data on your iPhone before proceeding with this step.

Here's how to do it:

  • Make sure your data has been backed up to iTunes, iCloud or your computer to prevent data loss.
  • Open the Settings app on your iPhone and navigate to "General" > "Transfer or Reset iPhone" > "Erase All Content and Settings."
  • Enter your password when prompted and confirm the reset.
  • This process may take several minutes to complete. Once complete, your iPhone will reboot and look like brand new.
