Is It Worth Upgrading?

The ‌iPhone 16‌ and ‌iPhone 16‌ Plus, while bringing some notable improvements, offer what might feel like an incremental upgrade over the ‌iPhone‌ 15 and ‌iPhone‌ 15 Plus for most users. The most significant advancements come from ‌Apple Intelligence‌ and the introduction of the Action Button and Camera Control, both of which provide new ways to interact with the device.

‌Apple Intelligence‌ is arguably the most important new feature, as it enhances the ‌iPhone‌'s ability to understand user context and assist in everyday tasks like prioritizing notifications, summarizing texts, and pulling real-time information through ‌Visual Intelligence‌. For users who rely heavily on their phone for productivity and communication, this AI-driven functionality is a meaningful addition. The Action Button and Camera Control button are welcome hardware changes, offering customizable, quick access to key functions and improved control over photography and videography.

Outside of these features, however, the upgrades feel more conservative. The performance gains with the A18 chip, new Neural Engine, and GPU architecture offer incremental improvements in speed and efficiency, which will benefit high-performance tasks like gaming, but may not be immediately noticeable for everyday users. The camera updates, including better ultra wide low-light performance and Macro photography, are valuable for photography enthusiasts, but they don't dramatically alter the overall camera experience for casual users. Similarly, the improvements in battery life and charging speeds are useful but relatively minor, providing a modest boost over the ‌iPhone‌ 15 lineup.

For users with an ‌iPhone‌ 15, the upgrade might not feel substantial unless you're looking to take full advantage of ‌Apple Intelligence‌ or the new buttons. If your phone usage revolves around basic tasks, the ‌iPhone‌ 15 remains an excellent device, and upgrading may not be necessary. However, if you're someone who is interested in AI or more intuitive camera controls, the ‌iPhone 16‌ offers enough to justify the switch. Overall, the ‌iPhone 16‌ is a step forward, but the upgrades are relatively modest.

These upgrades are so subtle. It does seem to add up over 3 or so years.
They seem to purposely hold things back from what they "could" do each year, in order to give themselves "new features" each year.

It's a pretty sad state of things ... to know we could be getting better devices sooner, but instead they stretch it out for maximum milkage of their customer base.

I wonder when, if ever, the base iphone will get >60Hz screen.

In any case, if this is true, 16 will be yet another gen I skip unless my 13 Pro breaks or gets stolen.
Yep its becoming a bit of a joke now from Apple. All the Galaxy S24 range of phones now have 120 hz Adaptive refresh screens (exactly the same as Pro-motion), and here we are in 2024 and the regular iphones still have 60hz displays, which is likely to follow suit with the Iphone 16 and 16 plus.

It is ridiculous that in 2024 Apple are still releasing standard iPhone for £800-£1100 with 60hz displays dual camera systems.
It is ridiculous but that pricing structure makes ignorant consumers justify spending insane amounts of money on their "Pro" phones when those features should be a bare minimum in this day and age. It's all about creating (or manipulating) a contrast.

I like my 15 tho. The battery life is great, somehow the camera seems better than I thought it would be. And the Dynamic Island is a nice touch. But they’re all really small things. Take it or leave it.
