With the release of IOS12 a few days ago I decided to jump right on in and upgrade my iPhone 5SE and iPhone 6 before getting the general upgrade invite. I usually hold back on upgrade preferring to wait until the dust settles and the issues if any are highlighted and sorted by Apple. However this time I was interested to see if the two key headline promises would deliver:
1. Major performance and speed improvements for older devices
2. Faster app launch on the iPhone 6
Over the last 4 days I've been using the iPhone 5 as normal and the phone does appear to be more responsive and "smoother" in its operation especially app opening. Battery life appears to be better. For general use (calls, texts, messaging and the usual browser usage I have experienced a slight improvement in battery performance however running power hungry apps especially maps will always eat power so I'm not expecting any major gains overall.
Much the same for the iPhone 6. Apps do appear to launch a little faster which maybe due to IOS12 alone or a combination of IOS and app updates that are now coming through as a result of the IOS release.
Not a subjective analysis I know however no negatives experienced so far.
