Some will wonder if it's worth upgrading from the iPhone 14 Pro Max to the iPhone 15 Plus. The iPhone 14 Pro Max is still a high-capacity phone; even an iPhone 15 Pro Max would hardly be considered an improvement. While the iPhone 14 cameras are adequate enough for general photography tasks, they have hardly changed from those of the iPhone 13 (except for the improvement in the range of images they use). Functionally speaking, however, these ports are identical, and the switch to USB-C offers improved data transfer speeds exclusively for the iPhone 15 Pro and iPhone 15 Pro Max.
Curiously, the iPhone 15 is also compatible with the new Qi2 wireless charging standard, which could mean that, in the near future, you'll be able to charge it to 15W with cheaper non-Apple charging accessories. That's right, you can say goodbye to Lightning cables when you switch to an iPhone 15. The new USB-C port on iPhone 15 that the EU forced Apple to add will allow you to upload and share files via USB-C, which means increasing file transfer speeds. The EU told Apple that it must add USB-C charging ports to all iPhones sold in Europe starting in 2024, but the company chose to follow that regulation a year earlier with the iPhone 15 line. With that said, if any of those scenarios are true, you're much better off going for the iPhone 15 Pro or the iPhone 15 Pro Max.
The aluminum side rails and the IP68 water and dust resistance ratings of the iPhone 14 have also been incorporated into suitable iPhone 15 models. In addition, Apple has abandoned the old mute switch on the side of the iPhone for a new action button on the iPhone 15 Pro and Pro Max. The dimensions and weight of both phones are almost identical (147.6 x 71.6 x 7.8 mm and 171 g for the iPhone 15, and 146.7 x 71.5 x 7.8 mm and 172 g for the iPhone 14), but they are two very different looking devices. The iPhone 14 is still a capable and durable phone for those who aren't interested in the details of the newer iPhones.
The question of whether you should upgrade to the standard iPhone 15 will, of course, depend on both the iPhone you're currently using and what you're looking for in a smartphone. The storage options are the same for both the iPhone 15 and the iPhone 14, with a basic 128 GB option, a 256 GB option and a 512 GB option at the top of the range. Apple says that this camera is so big that it requires more space than the iPhone 15 Pro can have, so you'll only find it on the most expensive iPhone 15 Pro Max.
