If your smartphone space is cluttered, you might face unexpected issues during the software update. While it’s not a solution per se, make sure to declutter your iPhone before downloading the latest iOS beta. That will only take up bandwidth and slow down the install process. Also, avoid watching movies on Netflix or streaming music while the beta is downloading. Thus, it’s better to keep the iPhone connected to a power source during the software update process. Keep Your iPhone Connected to a Power Source During Software Updateĭue to the large file size, iOS 15 may take longer than usual to download. Thus, it’s always better to download the software after a few days of the official rollout. Since a large number of iPhone users rush to download the latest iOS beta as soon as it’s rolled out, Apple’s server might find it hard to cater to the high demand. If the iOS 15 update gets stuck or takes too long to download, even if you have a stable internet connection, then Apple’s servers could be at fault. Since the download size of iOS 15 is huge (around 5GB to 6GB, depending on your iOS 15 compatible iPhone model), a stable internet connection helps ease the download and installation process.

If you have a stable internet connection with fast download speeds, it should only take around 5 to 15 minutes to download the latest version of iOS. As to how much time iOS 15 takes to download and install, it entirely depends on the internet connection speed.
