iOS 11.4 Developer Beta 4 released yesterday to developer testers only. The public beta version of iOS 11.4 will probably be available for public beta testers either today or tomorrow. We are now into the fourth iteration of iOS 11.4 betas. Therefore, we can expect to see the final beta before WWDC 2018 or at WWDC 2018.
So far, the update has been good. The update was about 413mb for me. I have a 64gb iPhone 6. The update was quite big meaning there are probably a lot of changes I have not discovered yet. This is because I only just updated today and have not used the new beta much. However, in the few hours I have used 11.4 Developer Beta 4, my iPhone has been fast. Animations are smooth like usual. Phone was a bit heated due to updating but other than that, it is normal. I am not sure how much storage I got back after updating as I tend to not worry about storage. However, for people that have 16 or 32gb iPhones, storage is important. Therefore, in my in-depth review of iOS 11.4 Developer Beta 4, I will research how much storage comes back when updating. How much storage comes back after updating also depends on many factors. For example, what storage capacity your iPhone has and the amount of storage you had before updating.
So far, the new update has been good. My iPhone has been fast and has been running like usual. However, as I use it for a few days, I will be able to write my in-depth review. In my in-depth review, I will discuss many things. For example, Speed and Performance, Battery Life, Performance while playing games, etc.
