The iPhone 15 Pro: A Comprehensive Guide to the Latest Technology

September 12, 2023

This roundup summarises all the information we currently know about the iPhone 15 Pro, with information on rumours about the normal iPhone 15 model accessible in the iPhone 15 roundup. The iPhone 15 Pro is anticipated to be the same size as the iPhone 14 Pro versions, at 6.1 inches.

As of right now, it appears that the iPhone 15 Pro versions will have a few small design changes. Apple will likely introduce slimmer, curved bezels and a new titanium material for the chassis in favour of the current stainless steel. Additionally, a new “mute” button that could potentially function as an action button, like the action button on the Apple Watch Ultra, is anticipated from Apple. The existing mute switch will be replaced with the so-called action button, which will be able to do more than simply silence the iPhone. According to rumours, users will be able to programme a number of features, including shortcuts and turning on the torch.

The iPhone 15 Pro and iPhone 15 Pro Max will be the only models to use the newer 3-nanometer A17 processor; the other iPhone 15 models will continue to use the iPhone 14 Pro and Pro Max’s A16 processor. The A17 chip’s greater speed and efficiency might lead to an improvement in both performance and battery life. Dynamic Island and the switch from Lightning to USB-C will be included in all iPhone 15 models this year, but the iPhone 15 Pro series will also have an improved USB-C connection with higher USB 3.2 or Thunderbolt 3 transfer rates.

The A17 processor is anticipated to come with more RAM, although all iPhone 15 models will use the same 5G Qualcomm modem chip for connection. In early 2024, Apple is anticipated to release the Vision Pro headset, which will integrate with a new Ultrawide Band processor, enabling close-by interactions. The main distinction between the iPhone 15 Pro and Pro Max’s features is the telephoto camera lens, which will be included on both models.

Both iPhone 15 Pro models will include telephoto lens technology as part of their typical three-camera array, but only the iPhone 15 Pro Max will have a new periscope lens that will enable 5x to 6x optical zoom, a significant advance above the 3x magnification on the existing iPhone 14 Pro models. According to rumours, the iPhone 15 Pro will be offered in four colours: titanium grey, silver, blue, and space grey. According to reports, the “star of the show” at the iPhone 15 announcement will be the camera upgrades.

What’s new in the iPhone 15 Pro?

What's new in the iPhone 15 Pro?

At its presentation on September 12, Apple is anticipated to reveal four new iPhone 15 variants. Pre-orders for the phones are expected to open on September 15. A USB-C connector and the Dynamic Island are rumoured to be features shared by all four versions, but the Pro models are likely to include many more features, including a titanium frame, a programmable Action button, an A17 Bionic processor, Wi-Fi 6E compatibility, and more.

Twelve alleged new features for the iPhone 15 Pro versions are summarised below:

  • It is lighter than the stainless steel frame on earlier Pro versions, thanks to the titanium frame.
  • Faster, more energy-efficient, and produced using 3nm technology is the A17 Bionic Chip.
  • Action button: Several tasks can be performed by swapping out the ring or silent switch.
  • A USB-C connector offers higher data transfer rates and is increasingly often used as a charging port.
  • There are new colour choices, including Titan Grey, Blue, Silver, and Space Black.
  • The bezels surrounding the screen are very thin and curved.
  • Wi-Fi 6E: Wi-Fi boosted to 6GHz band, higher wireless rates with compatible router
  • 8GB of RAM and 2GB more for multitasking
  • Periscope telephoto lens: The iPhone 15 Pro Max is the only device with this up to 5x-6x optical zoom.
  • Following in the steps of the iPhone 14 and iPhone 14 Plus, a more repairable design
  • Ultra Wideband Enhancements: U1 Chip Upgrade in Advance of the Vision Pro
  • There were additional nations where SIM card slots were eliminated, including maybe France.

Design and display

Design and display

Two of the 15 line’s greatest updates this year will bring Apple one step closer to the ideal iPhone. The Dynamic Island will replace the notch on the normal iPhone 15 models, while the Pro and Pro Max displays will use a brand-new manufacturing technique called low-injection pressure LIPO, as it is referred to internally at Apple, is over-moulding.

The new procedure would reduce the border surrounding the display from around 2.2 millimetres on existing iPhones to 1.5 millimetres.LIPO was first used to increase the display and thin out the borders of the Apple Watch Series 7 gadget. According to what I’ve been informed, Apple also intends to ultimately add this capability to the iPad.

The iPhone 15 and 15 Pro lines will receive a number of new capabilities in addition to the bigger displays, making this the largest update since the smartphone introduced 5G connectivity three years ago.


There have been rumours of further enhancements in addition to the 48MP primary camera and periscope telephoto camera, which are the two major upgrades to watch out for.

For starters, the iPhone 15 Pro versions could come with an improved LiDAR sensor. These phones employ LiDAR to support portrait-mode photos and AR apps, but this new sensor’s enhanced power suggests that it may be able to do more. However, given that feature is anticipated for the iPhone 16, we don’t believe it will deliver fully Vision Pro-level spatial image and spatial video recording.

The iPhone 15 series is also rumoured to employ a new Sony sensor with a bigger footprint and a “triple-stacked” construction for enhanced light intake. This rumour may or may not be genuine. The cameras in the iPhone 15 and iPhone 15 Plus may be dual-stacked, but there has been no mention of the camera sensor’s size growing. We are persuaded by another source’s assertion that this might really be a camera for the iPhone 16 Pro that will be released in the following year.

Additionally, we’ve heard that the ultrawide and telephoto cameras may exchange positions to suit shifting camera sizes, though this is unlikely to have an impact on the quality of the iPhone 15’s photographs. When covering the cameras up purposefully or accidentally, or if you’re unfortunate enough to fracture a lens, it’s something to be aware of.

The iPhone 15 will probably have at least one new camera mode, even if there haven’t been any explicit rumours about new camera modes or other software upgrades. A new camera function or processing system should be available on all four iPhone 15 models this time around, continuing a trend that Apple has established with its recent iPhone releases, which have included features like Cinematic Mode, ProRAW and ProRes capture, Photonic Engine, and Action Mode video.

Performance and Battery Life

Since other power-hungry components like the display and 5G modem will still be present, the A17’s up to 35 percent reduced power usage is unlikely to be sufficient to improve the iPhone’s battery life alone. The iPhone 15 Pro models might boast a significant gain in battery life over the previous model if Apple makes efficiency improvements to these other crucial components.

The A17 Bionic processor is expected to be a considerable advance when combined with the performance improvements that the 3nm technology delivers. Apple’s high-end iPhone 14 Pro and iPhone 14 Pro Max models were the only ones to receive the A16 Bionic chip last year; the iPhone 14 and iPhone 14 Plus continued to use the A15 Bionic chip from the prior year. Only the two most expensive versions are anticipated to receive the A17 Bionic in the iPhone 15 range, while the iPhone 15 and iPhone 15 Plus are anticipated to receive an update to the A16 Bionic.

Though TSMC’s 3nm manufacturing lines are thought to have Apple as their largest customer, there have lately been questions about the supplier’s capacity to handle Apple’s significant order volumes. In the autumn, the iPhone 15 and iPhone 15 Pro versions are anticipated to be on sale.

Apple’s next-generation A17 processor, which is anticipated to be the first A-series semiconductor produced using 3-nanometer technology, will power the iPhone 15 Pro and Pro Max.

Because of an increase in transistor density brought on by the switch to a newer technology, chip sizes will be smaller. The A15 and A16 CPUs, which are both utilised in the iPhone 14 versions, were created using processes using 5 and 4 nanometers, respectively. With one extra GPU core than the A16, the A17 processor will have a 6-core CPU and 6-core GPU.

The 3nm technique, which TSMC has been trying to perfect for some time, is anticipated to boost processing performance by 10 to 15% while lowering power consumption by as much as 30%. The A17 processor will only be accessible in Apple’s iPhone 15 Pro versions in 2023 due to 3nm chips’ higher manufacturing costs. We could see a longer battery life as a result of the increased efficiency.

The A16 processor will be utilised for the basic iPhone 15 models, according to code discovered in the tvOS 17 beta. The A17 chip will only be available in two of the future iPhone 15 versions (the Pro models).


The current iPhone 14 Pro versions have 6GB of RAM, but the iPhone 15 Pro and Pro Max might have 8GB of RAM instead. However, one source suggests that smartphones will still have 6GB of RAM.


It is possible for the iPhone 15 Pro models to support up to 2TB of storage, which would be twice as much as the maximum storage capacity of the iPhone 14 Pro models, which is 1 TB. The iPhone 15 Pro versions may also start with 256GB of storage rather than 128GB; however, rumours have conflicted on this.


The iPhone 15 Pro will be introduced on September 12 during an event hosted by Apple, and four variants are anticipated to go on sale for pre-order on September 15. The iPhone 15 Pro versions will include an improved 3-nanometer A17 processor, a Dynamic Island, a slimmer, curved bezel, a new titanium material for the chassis, a revised “mute” button, and an Apple-enhanced USB-C connector. An Ultrawide Band processor will also be part of the iPhone 15 Pro range, and it will work with the Vision Pro headset to facilitate interactions with people around you.

There will be a significant difference in the telephoto camera lens because the iPhone 15 Pro Max has a new periscope lens that offers 5x–6x optical zoom. The colours blue, silver, space grey/black, and titanium grey will be available for the iPhone 15 Pro versions. The “star of the show” at the iPhone 15 announcement is likely to be the camera improvements. Additionally, the iPhone 15 Pro variants will have a USB-C connector, the Dynamic Island, a titanium frame, a programmable Action button, an A17 Bionic CPU, compatibility for Wi-Fi 6E, and a periscope telephoto lens.

The iPhone 15 series, which will have two significant design modifications, will be introduced by Apple in September. While the Pro and Pro Max displays employ low-injection pressure over-moulding (LIPO), which reduces the display border size to 1.5 millimetres, the regular versions will transition to Dynamic Island. LIPO was originally applied to the Apple Watch Series 7 in order to reduce the device’s bezels and enlarge the display. 

In addition, the iPhone 15 and 15 Pro lines will include improved LiDAR sensors for portrait-mode photos and augmented reality applications, as well as Sony-built sensors with a bigger footprint and a “triple-stacked” construction for more light intake. In order to accommodate shifting camera sizes, telephoto and ultrawide cameras may alternate positions. There haven’t been any particular rumours concerning additional software or camera settings, although all four iPhone 15 models are expected to contain them. With a potential reduction in power usage of up to 35%, the A17 Bionic chip is anticipated to represent a substantial boost.


What is the new technology of the iPhone 15?

All four of the iPhone 15 models are anticipated to convert from Lightning to USB-C connections, with the Pro variants anticipating up to 35W charging rates. An A16 Bionic processor is anticipated to power the iPhone 15 and iPhone 15 Plus, while the iPhone 15 Pro versions will be powered by the upcoming A17 Bionic.

What makes the iPhone 15 better?

Apple’s iPhone 15 Pro series is anticipated to have more curved front glass that blends better into the frame and a titanium chassis rather than a stainless steel one. The iPhone 15 Pro versions will be lighter and more robust, and the titanium material will have a more matte, brushed appearance.

What are the expectations for the iPhone 15?

The notch, which has been present on iPhones since the iPhone X series, is anticipated to disappear with the next iPhone 15. The Dynamic Island, which made its debut in last year’s model, will take its place. The amount of screen space available to consumers will grow as a result. Also anticipated is a reduction in bezel size.

What is the iPhone 15 release date?

New Apple hardware, including watches, AirPods, and other accessories, will also be unveiled at the event. For fans of Apple, the newest iPhone would be the major attraction at the unveiling. At 10:30 p.m. IST on Tuesday, September 12, Apple will release the iPhone 15 publicly.
