You will notice and enjoy the upgrade after 4 gens. Example: 11 to 15

For me it’s optimally 4 years Maybe 5 if the battery is fine (with 1 battery replacement around the 2.5 year mark).

But I’m also not a “power user” I just get the base one and I’m good for a few years. Even now I have the 13 base 128 GB and I’ve only used up around 50 GB (this includes 10GB iOS, 10 GB System data and 11 GB photos and that’s a full 2 year’s worth without enabling optimise photos). I’m guessing this is also why I don’t generally notice a lot of bugs.

3-4

When Apple stops providing updates or in the case of my watch after the battery health went down below 80% as we don’t have watch battery replacement here. My watch is S4 and it just reached 5 years now.

Well before this one, I wanted a new phone everytime a new one came out, but always got a phone 2 years later. But now I’m starting to not be so materialistic about it, especially with how 1. Phones are super expensive, 2. If the device is working fine no need to get a new one. So I’m happy with the new mind set I have. I will be happily keeping this phone until it’s no longer support, or it breaks (but I have AC+)

I’d say 3 years at the very least. However, I had the iPhone XR since it came out in 2018 until I replaced it with the new iPhone 15 pro last month. So I had an iPhone XR for 5 years, and I was even planning to push it for one more year, and if I did, it’ll work fine, but I decided to get a new one in the end.

5years at least

I’d say after one official battery change at Apple - original batt and reasealing the phone. Each battery should last you 2+ years, so you’d get 5+ years out of the phone.

I’d say that’s a good balance of device price + battery replacement price for a lifespan usage of 5 years, instead of 2x device price for example.

Hi guys, thank you for all the comments i will say that we should upgrade our new iPhones every 4 to 5 years. Why? Because every new iPhones these days have little diference that the previous models. Take the example of iPhone Xs first apple bionic chip it runs faster then the android phones that year. 🩷

Still on the 11 pro and not buying another apple product until they get rid of the notch it’s so ugly

6 or when it breaks

4 years. I had a 12 pro max that I loved. I waited and would’ve continued to wait but the usb c switch was a bit important to me… otherwise everything is solid and the the updates kept rolling
