Although we haven’t seen new iPhone 15 models until September 2023, rumors have been circulating for months. It appears that the iPhone 15 models may receive more significant updates than the iPhone 14 did, including features that many iPhone users have desired for years.
MacRumors readers now know what to expect from the iPhone 15, so we’ve compiled a list of some of the best rumored features.
USB-C
Apple is expected to switch to USB-C in 2023, which means you’ll be able to charge your iPhone, iPad, and modern Mac with the same connector. The Lightning port on the iPhone is expected to be discontinued.
Apple is not actually switching to USB-C to make your life easier; rather, the European Union has demanded that it do so. By 2024, iPhones sold in Europe must have USB-C ports, so Apple must either change the design of all iPhones or make iPhones just for Europe.
Rumors suggest that Apple will make the change in 2023, and the company has confirmed that it will abide by local regulations.
Touch Volume and Power Buttons
Touch Volume and Power Buttons According to Apple analyst Ming-Chi Kuo, the iPhone 15 might have solid state volume and power buttons instead of physical buttons. These buttons would be similar to the trackpad on Macs and the Home button on the iPhone 7. The mechanical button press would be replaced by haptic feedback, which would replicate the sensation of pressing a solid button.
Apple might be able to offer improved water resistance by using solid state buttons, which would likely prevent water from entering the device. Apple would need to develop new Taptic Engines in order to implement haptic feedback for buttons.
Dynamic Island for All Models
Dynamic Island for All Models Apple introduced the Dynamic Island on the iPhone 14 Pro and Pro Max, whereas the less expensive iPhone 14 models keep the notch. The Dynamic Island is expected to be included in the entire iPhone 15 lineup; therefore, if you want access to the Dynamic Island but don’t want to buy a Pro iPhone, wait for the iPhone 15. Same Sizes We haven’t heard any rumors about significant design changes for the iPhone 15 lineup as of yet, so it appears that we will receive the same sizes. The iPhone 15 and 15 Pro will have a screen size of 6.1 inches, while the iPhone 15 Plus and Pro Max will have a screen size of 6.7 inches.
Periscope Lens
Technology for Periscope Lenses We’ve been hearing about Apple’s work on periscope lens technology for a long time, and it’s possible that it will be released in 2023. Some Android smartphone manufacturers already use Periscope lenses because they have optical zoom capabilities that are greater than those of a standard telephoto lens.
Apple could offer optical zoom of 5x or even 10x with a periscope lens, up from 3x on the current iPhone 14 Pro models.
3-Nanometer A17 Chip
3-Nanometer A17 Chip Apple supplier TSMC’s iPhone 15 Pro models may be the first to feature a 3-nanometer chip. Processing performance is anticipated to rise by 10 to 15% using 3nm chip technology, while power consumption is anticipated to decrease by up to 30%.
In the event that Apple utilizes a 3nm A17 chip, it would be a prominent improvement over the A16. The A16, which is made using a 4nm process, was only available for the Pro models, and the A17 is also expected to only be available for the iPhone 15 Pro. The A16 from the previous generation may be upgraded for standard iPhone 15 models.
“Ultra” iPhone 15
Mark Gurman of Bloomberg says that Apple might make a new high-end “Ultra” iPhone 15 instead of the “Pro Max” version. That would be consistent with the Apple Watch Ultra, and it could provide Apple with an excuse to restrict certain features, such as periscope lens technology, to the most expensive iPhone.
Ming-Chi Kuo, an analyst at Apple, has previously stated that the periscope lens may only be available on the largest iPhone.

An increase in RAM capacity—from 6GB to 8GB—may be added to iPhone 15 Pro models in order to support new features like periscope lens technology.
