Reading through the responses, I have the following observations, Both Fingerprint and Face ID require a physical action and to use the phone one must always touch it in some way to achieve this.
As for battery life suddenly dying or not being so good, I have had this on most phones from both platforms that I have owned (Many iPhones and many Pixel and Samsung phones) but not on this S23 Ultra but will do so at some stage.
I think that autofill is slightly better with iOS but, I have 1 Password and tbh, it's not a dealbreaker.
I can't tell any difference on the fluidity between the two. Both are very smooth.
If I had only one app, using an iPhone Max, it would be placed in the top left corner of the screen and there is nothing I could do about it, using my S23 Ultra, I can and do, put the apps exactly where they fall under my thumb.
As for "The ecosystem," look at my sig and see the different tech equipment I have, add in Sonos, Philips Hue, Ultimate ears etc, it all works together and I'm a grumpy old man of 65 with no patience whatsoever and little to no technical knowledge, if you are so worried about this "eco system" you are either just making excuses, (which is okay, I did the same thing when I had all Apple) or are less technical gifted than me, which is a sad state of affairs on such an esteemed technical forum.
I can't comment on shutter lag because I have not experienced it.
Changing the charging system doesn't bother me in the slightest, I have never had a problem with either, so long as the wire is included when the phone is first purchased, I have a charger that will fit it, it's a minor gripe, having said that, the iPhone and my iPod Pro are the only items that I have recently owned that use Lightening adapter. Truthfully, I just plug my phone in to charge and don't give it a second thought.
I find the Google assistant the best and use it on my phone, I use Alexa in the house.
I find that Apps on both platforms are just as slick as each other and those that say otherwise are very finicky or have never used a flagship Android device and fall into the same category as those that say "Android phones lag," that may have been true 6 or 7 years ago but is none existent on flagship phones these days, I will have to ask my butler if the same is true for cheaper Android phones.
The stock music identifying thingy on an iPhone is no where near as good as the same thing that Google use. When I had a iPhone 14 pro, I gave up using it, it's that bad.
I find that the speakers produce a better sound on the S23 than the iPhone, but, I'm partially deaf so one should make up their own mind.
I find that the reason people often "go back" (either way) is just because the systems and way of doing things are so different and it becomes frustrating. Opinions are made too quickly and within the first 2 or 3 days, honestly, stick with it for a week or two and that epiphany moment will come, you will wonder why you never used an Android or iPhone before, because they are both superb, you are just used to doing it a different way, and therein, lies your bias.
