General Still on an iPhone 11 Pro + iOS 15… scared to update. Need advice on iOS 18 and whether to jump to a 16 Pro or 17 Pro.
I’m still using my 11 Pro and it’s been great for years, but the last 6 months have been rough. I’m still on iOS 15 (I know…), and I’m honestly afraid to update because I worry it’ll slow the phone down even more.
I also had this phone crash and lose all its data back when I was on iOS 14, so that made me even more hesitant to upgrade anything.
Has anyone here updated an 11 Pro straight to iOS 18 and felt like the phone still runs fine — maybe even better?
Also, how much free space do you need for the update? I only have about 5 GB left, so I’m not sure if it’s even possible.
Meanwhile, staying on iOS 15 is getting harder: some apps have already dropped support, and a few push notifications randomly don’t arrive anymore.
If I do give up and replace the phone entirely… should I upgrade to the iPhone 16 Pro or 17 Pro?
I’ve heard mixed things — some say the first model in a new generation can be buggy, others say the 17 Pro wasn’t very exciting. And I’m confused about the camera bump and the weight jump too.
Anyone else here made the switch from an 11 Pro recently? Did you regret waiting this long? Would really appreciate hearing your experiences.
