As a former owner of iPhone 14 Pro Max who now owns an iPhone 13 Pro, unless you use the photography and videography capabilities of the iPhone to the fullest, and want USB Type C, you should still be fine with your current phone... After weighing the pros and cons, I decided to switch since I am not maxing out the hardware capabilities of iPhone 14 Pro Max, and I prefer shooting in ProRAW, but shooting in 48MP takes a considerable amount of time... Also, low light photo and video may be improved by Photonic Engine, but a wider aperture and shorter focusing distance to me is better...
Yes, I traded the longer battery life for easier handling... After looking at many things, just like some reviewers said, iPhone 13 Pro is still one of the best, if not the current best, and can still go head to head with the upcoming iPhones...
I still believe the switch to USB Type C should have been done in 2020, the year of iPhone 12... Transferring big files quicker is a nice to have and a must have for some, as well as record directly to an external SSD storage, but AirDrop to me is still sufficient and I find it fast enough as well as convenient... Maybe, many years later, once there are more and more features that I can't live without, that may be the time I'll go for the latest and greatest...
Anyone who owns an iPhone 12 series should upgrade for the primary reason that they have lower battery capacity than the previous and the series after it...
