Apple Released, iOS 13.3 about 2 days ago, as a part of their continuous update cycle. IO had been BETA Testing 13.3, and during the BETA, one thing I noticed on my iPhone X (The device I use for iOS BETA Tests) was that RAM Management was quite a lot better, with not as many or any apps closing or reloading, when they had been put aside in the background.
Now after 48hrs of Official Release of 13.3, on my 11 Pro Max, I have noticed that things are much smoother, with no background apps needing to reload when. Multi-tasking became a ease for me, someone who constantly moves between multiple tabs.
And as for IF, on my iPad Pro, I noticed that I’m with 13.3, and in combination with turning Anti-Aliasing Off, was able to fly for more than 15hrs. I’m currently doing another 11-12hr flight, and if this one too, goes as planned, then, I can be a bit more sure that 13.3 did indeed fix RAM Management issues to a further extend than what the previous Update 13.2.3 did, but there are still times App Crashes or needs to reload, and this and that, so there are many major flaws left that should hopefully be addressed in future updates.
