Are there performance or battery differences with iOS 18 on an iPhone 13 Pro Max?

I have a iPhone 13, I recently updated and at first it seem like it used a lot more battery due to background stuff for still updating the iOS, bit as I’ve read on a couple of threads that it may take a couple days for your battery usage to somewhat go back to normal

Ive had my IPhone 13 for about a year now and it’s been about a week since I updated and my battery level is at 99% and has been at the for 6 months, and the updated seemed to make me have to plug it in at night due to it being close to 10% at night in the first couple of days after the update.

since then my phone battery has lasted a day, maybe two; depending on what you’re doing (Music, Videos, Streaming and what not)

Basically I do like the update and I’ve heard of people’s phone battery’s not lasting as long as they usually would, but in my case it’s been working properly and as I said the first couple days were draining faster then it used to be and then it went to my usual

No noticeable performance issues on iPhone 14 Pro Max and iPhone 15 Pro Max upon installation of iOS 18. Battery performance is similar to iOS 17.

Initial thoughts are.......some things are different.

Performance is no better or no worse than previous versions.

iPhone 13 Pro Max.

Ever since my first iPhone (6 max, large, pro - whatever) I’ve found that virtually every “update” to be one step forward, two steps back. More complexity, (slower because of that), features changed for no apparent reason, counterintuitive operation, and pretty much everything taking more taps, swipes and scrolls than before. An easy example of this is the new settings menu, which is one of the two steps back. Another example is the user guide to ios 18. Why must I be online to access it? I only have cell service at home. I live in a forest which burned down in 2020. After we rebuilt, the cell service was acceptable because there was less foliage on the trees. Now that the redwoods are growing back their foliage, our cell service has become intermittent again. A downloadable user guide would be nice. Another example is the fingertip contortions now necessary to move the cursor through written text, which makes it harder to correct a mistake. Too many options are offered in a misguided attempt to “help”!

Ios 18 to me is a continuation of what I see as Apple’s obsession with a “change just because we can” and “change because it makes us look progressive” attitude. Increasing complexity, unnecessary options, irrelevant cutesy new additions, and confusing logic about the very operation of my phone.

One step forward, two steps back.

I am a dissatisfied customer.

Once again!

So far, with one huge exception, I’m happy with the update on my iPhone 15. The changes to the photo app is atrocious! I hate what they’ve done. Yes, you can customize the app, but it’s still not, IMHO, as useable as the older version.

I am now using iPhone 13 Pro and update iOS 18 last week before that I bought AirPod 4 in advance. But now I am using AirPod with iPhone in couple of days, I discovered that I listen to music when I hold my phone bottom right, the song will be paused. When I hold phone to up, this will be recovered. I previously used AirPod 3, this situation doesn’t occur.

very disappointed in the apple music bugs. other then that i can’t complain
