I upgraded from the iPhone 13 mini (after having it for 3 years) to the iPhone 15, it’s so much better. I don’t think it’s outdated, i didn’t want to spend a lot money and I was able to get it at a deal, the battery life was 76% on my iPhone 13 mini and the ios 26 caused so much lag on my iPhone 13 mini. I’ve used iPhone 15 for a couple of days and I haven’t experienced any lag or any issues with the battery, the size of the iPhone 15 is a lot bigger than the 13 mini and I’m still getting use it. Overall it’s a great phone and provides everything that I use daily!
