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?

• 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.

However, please note that due to iOS's robust security measures, access to and functionality of third-party antivirus applications may be restricted.
