How to Upgrade iPhone 13 Max Pro to iOS 15.1

The Apple iPhone 13 max pro does not have an edge over the iPhone 13 Pro in terms of features. Though iPhone 13 max pro is heavy and unwieldy, the big display is great for games and the increased battery capacity allows for nearly two full days of regular use.

The display of the Apple iPhone gets a 120Hz refresh rate, but there is still an unsightly notch that interferes with movies. The iPhone performance is great thanks to the A15 Bionic SoC. Users can choose between 128GB, 256GB, 512GB and 1TB storage options.

Upgrade iPhone 13 Max Pro to iOS 15 1 Pro

Recently, Apple announced that iOS 15.1 has been pushed out for iPhones users across the globe. The iOS update comes packed with many treats including the long-awaited SharePlay option. The SharePlay features were first announced by Apple earlier this year in June during WWDC Developers Conference which allows anyone to share their music, film, or TV show with friends and family on a FaceTime call.

The playback of the music and video feed is synced across everyone’s devices, so friends can add new songs to a queue or pause a film to talk about a specific sequence on everyone’s iPhone or iPad. Disney+, TikTok, and several other streaming apps have already committed to implementing the feature.

Users will be able to share what is happening on their screens. Both of these features were originally planned for iOS 15 but missed the deadline. However, it’s great to see these exciting new features – perfect for anyone who can’t travel to see friends and family right now.

As well as SharePlay, iOS 15.1 also includes some upgrades to the camera on the iPhone 13 Pro and Pro Max. Both devices now can shoot videos in the ProRes format.

How to get the Upgrade

Go to setting on your iPhone 13 max pro and choose General, then Software Update. Once you have clicked on Download and Install, it will work like a magic. This is a medium-sized update—1.44GB on iPhone 13 Pro Max, give it a little while to download and install.
