iPadOS 15.4 Review

If your tablet is currently running iPadOS 15.3.1, then iPadOS 15.4 requires a fairly large download.

If your iPad is running an older version of iPadOS, your download may be larger. That’s because the features and fixes from iPadOS update(s) that you skipped are baked into your version of iPadOS 15.4.

Installing iPadOS 15.4 takes about 10 minutes. It took about seven minutes to install on one of our older iPad Pro models.

Check out our guide on how to download and install iPadOS 15.4.

  • Battery life is stable.
  • Wi-Fi connectivity is fast and reliable.

App performance

  • Third-party apps like Netflix, Dark Sky, Twitter, Slack, Asana, Gmail, Chrome, and Spotify work fine.

If you can’t handle the performance of iPadOS 15.4 on your iPad, keep in mind that you can’t downgrade to older iPadOS software.

Apple has stopped signing on iPadOS 15.3.1, which means you can’t revert your iPad to the previous version of iPadOS to improve performance. Unfortunately, you also can’t revert your iPad’s software to anything older than iPadOS 15.3.1.
