That's hilarious because I just switched back to iOS for the first time since the 12 Pro Max.
Things I've noticed:
1) Standby drain is so much better. My OnePlus 13 can't match my 16e unless I have basically nothing installed.
2) Notifications are no longer delayed or entirely missing, another improvement over recent Android devices where notifications can be delayed by hours or just be missed entirely.
3) App quality is so much better on iOS. I'm honestly shocked at how much better common apps like X and Reddit are on iOS. There's no comparison. This extends to games too. They just run much smoother on iOS than they do on Android because devs optimize for iOS.
4) Universal Spotlight search is SO much more convenient for how I use my phone. I use search rather than clutter up my home screen on my devices and I get so irritated with the fact that Google's search built in to the launcher pulls up the Google app, which means if I want to grab a 2FA code from Authy, I have to swipe twice to get back to the last app I was using. Since gestures on Android are less precise than they are on iOS, this often means I have to swipe three times to actually get back to the app that needed the code and then Android even closes the keyboard so I have to tap and bring that back up too, which always has about a half second lag no matter the device as well. I bring this up because it's a constant issue. Spotlight doesn't count as an app so I can use it, search for and open Authy, and when I swipe I go right back to the app that needed the code. None of this even touches on just how much more Spotlight can search. How Google hasn't implemented their own universal search is beyond me (and implementations by the OEMs are always lacking and clunky).
5) Google has started to make some annoying decisions that make the iPhone better for power users. For example, I use Microsoft Phone Link to get my notifications on my PC. With Android 15, Google now decides some things are too sensitive to show, and there is no option to get around that. Guess what? The iPhone pairs with Phone Link and shows me every single notification that comes in just as I want -- bonus points, I have yet to have it disconnect from my PC unlike every time I use an Android phone with the app nor have I had it fail to connect automatically when I bring the computer back from sleep, another constant fight with the Android phones. Google is also making it harder to sideload apps, not allowing them to have all the same permissions as apps installed from the Play Store without workarounds in settings (and OnePlus goes further here, not allowing you to override this limitation at all), while Apple is becoming less restrictive about allowed apps, which means I don't even need to sideload on iOS anymore.
6) On with the annoying decisions that Google is making, they're also going to make it harder to hide the fact you're rooted from apps. I have to root to be able to tolerate Android, as it allows me to undo Google's interference in how i use my device, but then I'm forced to give up tap to pay, banking, games, because of root detection. It's my phone, let me use it how I want!
Yes, the keyboard isn't the best. That's definitely something Apple should address. iOS 19 is said to be an entire design overhaul so it seems I moved at the right time but now that I can put icons anywhere I want on the screen, I'm not really that annoyed by the iOS interface anymore. I do hope Apple implements the ability to swipe to go back to the previous app at some point though. That particular gesture is very inconsistent and it's taking some getting used to. Like if I open a link from my email on my Android phone, I can swipe to go leave the browser and go back to my email, but on iOS, I have to tap the arrow in the top left corner. That's minor though and I'm getting used to it.
I don't care about the AI stuff one bit but yeah, if you want more of that nonsense, Android will give you that.
Anyway, I can't see myself going back to Android any time soon. Google has stepped up the nannying to a level I just can't tolerate anymore while Apple has relented in many ways and I am just so tired of fighting with my phone. Everything with Apple just works.
