As someone who started with Android, went to iOS, back to Android, and stayed with iOS I feel like you're not trying to understand why some people choose an iPhone. I personally chose it because of the incredible battery life.
Skip the rest of this if you don't want to hear a rambling mess of my phone history. There is a bit at the end regarding prices and why I own what I own now.
I had an HTC Desire, Samsung Galaxy S2, HTC One M7, Sony Xperia Z1, iPhone 7, Nexus 6P, iPhone X, iPhone 12 Pro, iPhone 15.
I've rooted a bunch of the early Android phones, loved having removable batteries and having expandable storage. As the platform evolved and started following Apple's lead on design decisions (no removable batteries, no expandable storage, etc.) I was wondering why I was still with Android. After having a the Xperia I noticed that the battery didn't last as long as it used to and if I remember right (possibly not, a bit tipsy) the Xperia was advertised as having a very long battery but it didn't last very long past a year or so (was getting less than a full day and having to charge when I was driving home). I also had how slow Sony was to get OS upgrades it I decided to try a new phone. At the time I cared more about the battery and the iPhone 7 was my next try. It was amazing, I didn't actually enable iMessage because I hated the bubble bs that I heard about. Eventually the 6p was announced and I missed the freedom of android and decided to give it a try. This was the generation where Android started cracking down on rooting and the battery life was awful. I eventually went full in on iOS after that and here we are. I miss what Android was, I do sometimes miss the tinkering but I also don't hate how things normally just work.
Now in regards to cost, the name brands for Android phones are around the same price. They usually promise 2-3 years of updates while currently Apple had a history of supporting phones for 4-5 years.
I understand you can get lower range phones for cheaper but I guess I'm not into the phone scene like I used to because I guess I assume the lower range phones aren't getting the updates that the flagships are and I don't want to have to either compromise security or shell out more money to get another phone. So for me, I'm typically buying around a $1000 phone but after 3 years I can trade in my phone for a decent amount of money off the new one, or sell it for even more and pay a mid range Android prices for a new iPhone. Or if I'm not feeling the upgrades are worth it I'll just stick with my phone for the 5 years+ (only went to iPhone 15 to get USB-C and remove lightning from my place).
