iPhone 15 vs. iPhone 16: 15+ Rumored Upgrades Compared

After over a year of reports, there are now over a dozen specific rumors about the features and improvements set to be offered by the two non-Pro iPhone 16 models later in 2024.

iPhone 15 vs 16 Feature Yellow Pink

All of the changes the ‌iPhone 16‌ models are expected to feature compared to their direct forerunners are listed below, using information from a range of reliable sources that we have previously covered. We will update this article as more rumors emerge in the coming months.

This guide focuses on the iPhone 15 and ‌iPhone 16‌, but to learn about how we are expecting the iPhone 16 Pro to improve on the iPhone 15 Pro, see our other comparison article.


The ‌iPhone 16‌ and ‌iPhone 16‌ Plus are expected to largely carry over the design of their predecessors, meaning that they will have the same dimensions. The most noticeable alteration that will denote the new models is said to be a vertical rear camera arrangement to facilitate spatial video capture, but the removal of the mute switch in favor of the Action button introduced on last year's Pro models and the introduction of an all-new "Capture" button will also be important changes.

‌iPhone 15‌ ‌iPhone 16‌
Diagonally arranged rear camera array Vertically arranged rear camera array to support spatial video capture
Ring/Silent switch Action Button
"Capture Button" to trigger photography and videography features
iPhone 15: 171g weight
iPhone 15 Plus: 201g weight
iPhone 16: 173g weight (+1%)
iPhone 16 Plus: 203g weight (+1%)

Chip, Memory, and Connectivity

The ‌iPhone 16‌ models are rumored to benefit from a moderate improvement in processing power thanks to an all-new A18 chip with a more power Neural Engine to support exclusive generative AI capabilities. We are also expecting 33% more memory and Wi-Fi 6E support.

‌iPhone 15‌ ‌iPhone 16‌
A16 Bionic chip (TSMC's "N4P" enhanced 5nm process) A18 chip (TSMC's "N3E" enhanced 3nm process)
16-core Neural Engine Enhanced neural Engine with "significantly" more cores to support new AI features
6GB memory 8GB memory (+33%)
Wi-Fi 6 connectivity Wi-Fi 6E connectivity

Batteries and Charging

The ‌iPhone 16‌ models could receive some major improvements in battery technology and charging, sporting denser batteries and faster charging capabilities. It is worth noting that the ‌iPhone 16‌ Plus is rumored to feature a smaller battery than its predecessor, but it is not clear how this will affect actual battery life.

‌iPhone 15‌ ‌iPhone 16‌
Single-layer battery technology Stacked battery technology for increased energy density and prolonged lifespan
iPhone 15: 3,349 mAh battery
iPhone 15 Plus: 4,383 mAh battery
iPhone 16: 3,561 mAh battery (+6%)
iPhone 16 Plus: 4,006 mAh battery (-9%)
Up to 27W wired charging Up to 40W wired charging (48% faster)
15W charging via MagSafe 20W charging via ‌MagSafe‌ (33% faster)

Other Features and Changes

The ‌iPhone 16‌ models are likely to receive several camera enhancements, such as spatial video capture for the Apple Vision Pro. While many of Apple's devices are rumored to receive a series of new AI-based features via software updates later this year, the ‌iPhone 16‌ models are expected to take these further with exclusive capabilities facilitated by a more powerful Neural Engine in the A18 chip and an upgraded microphone.

‌iPhone 15‌ ‌iPhone 16‌
More efficient OLED display with brighter micro-lens technology
Spatial video capture
Upcoming support for new AI features in iOS 18 Upcoming support for new AI features in ‌iOS 18‌, plus a suite of device-exclusive AI features

C'mon, Macrumors, have another glance at those numbers and then tell me with a straight eye that 173 is 0,01% more than 171. :-)

These upgrades are so subtle. It does seem to add up over 3 or so years.

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.

The action button for me is just one of those innovative things, that don’t seem like much at first glance…but the flexibility is amazing.
While I'm pro-Action Button, it does feel like a toe-dip into something more robust. Interested to see how it evolves.
Hopefully, that vocal anti-Touch Bar posse doesn't also come for the Action Button. ?

Those are some decent upgrades to the "base model" phones, but I guess we'll have to wait until the iPhone 17 before we see 120Hz...
