Secondly, thermal management. The 13 mini heats up pretty quickly using it for mundane tasks, like texting. Normally, I wouldn't mind this, but with summer coming up, I’m a bit worried about the hot weather with it. In my car, this is very noticeable with wireless charging and wireless CarPlay. When Carplay starts to stutter a lot, I know my phone is getting hot.
Third, I've had two instances since I bought it where phone calls just didn’t go through. The first time, the person calling me received some kind of error (I got the same error with an outbound call), and the next time, the phone was ringing on their end, but nothing appeared on my screen. Both times were fixed with a phone reboot. I’m not sure if this was the phone itself, or my cheap carrier (Visible), I’ve never had this problem with the 14 Pro. Data and SMS both worked during these times.
Fourth, the battery life. I incorrectly stated in a thread about a month ago that my 13 mini with 100% capacity lasts longer than my 14 Pro at 82% capacity. Without looking at any numbers, just using it day to day, the 14 Pro definitely still gets through the day just fine, while the 13 mini needs at least a small charge during the day at some point. I use always-on-display and the 120hz frame rate on the 14 Pro.
