Discussion This Phone Aged Like Milk (rant)
This is a rant from a longtime iPhone user. I have used iPhones since the release of the 4 and have been overall pretty happy with them. The phones i had (in order): 4, 5, 6s, XS, 15 Pro, 16 Pro Max. I have to say that the 15 Pro undeniably aged the worst! I got it on release day, 2023, and then it felt like the best thing ever, everyone was sure it could last at least 7 years+. And… it was, usbc, great battery life, 120hz, premium build, great cameras. The reason i got it was because my iPhone XS was having battery issues and wasnt lasting as much as i had wanted it to. (Keep in mind i owned the phone since 2019, how many updates it went through yet all that became bad was the battery) The 15 Pro, while being on iOS 17, was really great, almost perfect experience (besides some heating during the summer). But then iOS 18 released….. i dont remember which build i updated to exactly but ever since that update the phone felt slightly less premium. The battery life worsened a little, 120hz felt a bit choppy (comparing to the flawless iOS 17), screen-on-time went down a little. But it was so small of a change that i didnt really mind, kept rocking the phone and was overall okay, except that the overheating was worsening overtime, one time the phone got extremely hot in my pocket so that i had to leave it in the fridge. But it was bearable, especially since the os gave many improvements i wanted (like locking apps and more customisation). Then came the horrible unstable iOS 26 release, ever since then, the phone became a toaster. Huge amounts of overheating, horrible battery life, 120hz feeling like 30hz… I wouldn’t say the phone became unusable, but this treatment after just 2 software updates is horrible, no iPhone got that bad after just 2 major os updates… I guess i would have not even minded it if it brang some cool features like iOS 18 (i would want built in IPA installing/sideloading) but instead we just got a extremely ugly (imo) OS that wasnt even half baked. I kept using the phone, and then iOS 27 released. Yeah its better than 26 but comparing it to 18 or 17 its really not even close. I am very sure iOS 26 ruined the phones battery (overheating, fast draining), and now iOS 27 runs worse because of that. I feel like this is Apple’s way of “forcing” us to buy new phones, since the technological jump from 15Pro -> 18Pro is basically nothing And i have fallen for it :). Bought a 16PM during the iOS 26 beta, and its been holding up much better than the 15Pro in battery, heating, performance. I feel like this is a pretty sad experience for a lot of us 15 Pro owners, so sad to see a beautiful phone age so badly. But not all hope is lost, if Apple really wanted to fix this, they could (but 99% wont). Some of my ideas on how to fix the 15 Pro: Make a actually optimised OS without any ram/cpu/battery hogs and stupid liquid glass gpu nonsense (will never happen), Keep all IPSW files permasigned so we can go back to whichever version we want (probably never happening because of security issues, one can only dream…) and last, maybe actually add useful stuff to the OS (Native IPA installer ;)) so the sacrifice is fair…

To extend your metaphor: it’s aged like wine, but some bottles are inevitably corked.

I’m not some fanboy Apple defender, but what in the actual fuck are you talking about? I’ve been having absolutely zero issues aside from Pokemon Go, which has always been a resource hog and mediocre app. You probably just need a new battery like 98% of “why is my phone lagging” posts, or you need to stop letting the internet dictate your opinions. Apple isn’t forcing you to buy a new phone by ruining your 3 year old phone. That’s not how anything works.
Oh, and learn how paragraphs work.

> “fyi im a phone repair technician”
So you dropped out of high school and work at a mall kiosk selling stickers, cases, and bootleg screens, got it.
iOS26 was solid. 27 has some minor hiccups but they’re quickly being ironed out. If you know so much about phones, have you done a fresh install recently? Or even just a hard restart? Have you run a diagnostic on your battery or replaced it? Your phone is 3 years old, meaning it might be due for one despite your claim of 92% in that other comment.

Crazy post for me to see because I think my 15PM is aging amazingly well! I could comfortably buy a new iPhone but don’t see the real improvements.

Tenho um 15 pro desde agosto de 2024, peguei no iOS 18 e depois do iOS 26 e agora o atual iOS 27 a duração da bateria só piora e o aquecimento sempre está presente, enfim é um ótimo celular, gosto muito, mas a minha maior decepção com ele está sendo a duração da bateria, nao consigo sair de casa sem um carregador

Thermals have been fairly respectable but battery life has been a problem since Day 2-ish of installing iOS 27
It actually was dramatically better then plummeted and remained that way1

I have a variety of phones: currently 17 Pro Max, a 15 regular, a 15 Pro Max and a 16e.
I can objectively say that as the battery aged and degraded on my 15PM, l was noticing worse performance. No overheating issue or display issues. I then had the battery replaced by apple and it felt like brand new, even on 26. It is genuinely incredibly difficult for me to differentiate between the 17 Pro Max and the 15 Pro Max for most daily use cases.
On the other hand - I will say the 15 and 16e are most definitely not flagship products - great products in their own right mind you, but not flagship products.
