Part 2. Why is iOS 14/15/16/17/18 Downloading So Slow?

When preparing your iPhone for a software update, ensure that you have a stable WiFi connection, and that cellular data is not enabled for an iOS software update. Simultaneously, you must keep the battery charged or the USB cord connected. So, if your iPhone is taking too long to update, consider the following possibilities:

1. Internet Connectivity

The Internet speed of the iPhone is perhaps the most critical aspect in deciding the length of an iOS 14/15/16/17/18 update. We recommend that you upgrade to iOS 14/15/16/17/18 via a WiFi network. The iOS 14/15/16/17/18 software upgrade will take longer to download if your Internet connection is sluggish or sporadic.

2. Region (Update Size)

The user's location is another crucial factor that determines how long does it take to ios 14 download. Not all Apple services are accessible in every country. While the majority of iPhone customers will see an iOS 14/15/16 software update file size of 4,79 GB, others will just need to download 2,83 GB to get iOS 14/15/16/17/18. That's because they're getting a trimmed-down version that excludes services that aren't available in their area.

3. iPhone Model

The iPhone model might also influence the size of the iOS 14/15/16/17/18 download file. Older compatible iPhone models can get a more pared-down version of the new iOS that works best with the resources available on their iPhones.

4. Available Storage Space

If your iPhone's available storage is at capacity for the iOS 14/15/16/17/18 update, it will attempt to offload apps to free up storage space. As a result, the iOS 14/15/16/17/18 software update will take longer to complete.

5. Moment Of Update

As iOS 14/15/16/17/18 is still in its early stages, the time you attempt to update is also critical. Many people are currently upgrading to the new version, which can quickly overload Apple's servers during peak hours. According to our experience, the optimal time to upload is in the early morning, when most people are still asleep, and the automatic updates have enough time to complete.

Part 3. How Do I Speed Up iOS 14/15/16 Download?

It would be unfortunate if the iOS 14/15/16/17/18 update takes forever. And if your device update has been stuck for an extended period, the update procedure is quite likely to have gone wrong. For the time being, you can attempt the following tips to fix the device.
