iOS 10.3 probably made your iGadget faster; or not?

Just over 24 hours ago, after numerous test versions, Apple released the iOS 10.3 for all compatible iPad and iPhones / iPod touch users. Fortunately, overall, user feedback on updates this time around is very positive.

Something that several have observed and commented on why the operating system would now be more ?responsive?, that is, that Apple would have made remarkable optimizations in terms of performance. And yes, there are some explanations for that.

Apple File System (APFS)

Apple presented, at the Worldwide Developers Conference (WWDC) 2016, a new file system that took its own name: Apple File System or simply APFS, for the latter. For those who want to understand it in detail, we have a complete post here.

If I were to guess, I would have bet that Apple would first implement APFS on one of its ?less important? operating systems if we can say so. Maybe not watchOS or tvOS, which are specific to owners of Apple Watches or Apple TVs. But no: she just chose her flagship, iOS, to start mass migration.

And so it was, officially as of yesterday: (almost) all iGadgets already updated to iOS 10.3 were also automatically migrated to APFS. This explains why this update takes a little longer than the others to complete, although fortunately without any problems.

The ?almost? in the paragraph above has a reason for being there: although iOS 10.3 has been released for all devices compatible with iOS 10, the migration to APFS only occurs on 64-bit devices, that is, iPhones were left out 5 and 5c, as well as the fourth generation iPad.

The migration to APFS by itself should already bring some performance gains in some devices, but apart from that there is another very positive side effect that many have commented for: there are people ?gaining? back some good gigabytes of space in their iGadgets after upgrading to iOS 10.3. Not bad!

32-bit apps

APFS may not have reached 32-bit devices, but iOS 10.3 itself has still been released for them and works without problems. What Apple is already doing, as we know, is preparing users for a 64-bit future.

Those already running iOS 10.3 can now go to General Settings About Applications to check the list of applications / games that you have installed and that will need to be updated by their respective developers if they want to continue running in future versions of the system.

iOS 10.3.2 beta vs. 32 bits

Since we are talking about 32-bit, an important note about the recently released first beta version of iOS 10.3.2: Apple * no * made available the compilation of tests for 32-bit devices, that is, developers with iPhones 5 / 5c and fourth-generation iPads are out.

The discovery was made by the YouTube channel EverythingApplePro, and we confirm it by visiting the Apple Developer portal. However, contrary to what they already say there, I do not give absolute certainty in the abandonment of these devices already in update 10.3.2.

Apple is starting to test iOS 10.3.2 now, along with its other operating systems, and there may have been some special reason why this first beta was not released for 32-bit devices. Of course, if it stays that way in future builds, it may have chosen this minor update to make the transition. But, if it were to kick, I would say she would only do that on iOS 11.

(Does this have anything to do with her skipping verse 10.3.1?)


Here comes a little bit of ?placebo effect?: Apple actually moved some animations throughout iOS in this update, making them faster / shorter. This, in itself, already gives a feeling of greater speed to many people.

Even though it is not actually a technical optimization in the operating system, the change is really welcome and most users have approved. The animation of returning to the home screen, for example, for me was much better.
