10 Things to Know About the iPhone 6 Plus iOS 8.4 Update

Why You Should Upgrade to iOS 8.4

The biggest reason to install iOS 8.4 on the iPhone 6 Plus today is that you want to use the new Apple Music service. There is no official time limit on the free three-month Apple Music trial, but many users simply want to test out all of the new features without waiting.

Another important reasons is if you are experiencing iOS 8.3 problems on your iPhone 6 Plus. I did not run into a lot of issues on iOS 8.3, but if you are having any issues the iOS 8.4 update may fix them.

If you own an Apple Watch you may want to install iOS 8.4 right now. While it does not bring a new version of WatchOS, it does fix a problem with Apple Watch apps reinstalling themselves after you delete them.
