Hello, how are you! I am Yuan Hehe, please follow me, more exciting content is waiting for you

In September, Apple will release the iPhone 17 Pro and iPhone 17 Pro Max, two new high-end flagship phones that will be released alongside the iPhone 17 and the ultra-thin iPhone 17 “Air” (which will replace the iPhone 17 Plus).

We still have a few months left until the new 2025 iPhones come out, but leakers, analysts and others with inside information on Apple’s plans have shared details about what we can expect from the new iPhones, so we have a pretty good idea of ​​what’s changing with the iPhone 17 series.

We have the iPhone 17 Pro and iPhone 17 Pro Max below, and for an overview of all the iPhone 17 models, we have a separate iPhone 17 roundup, and there are also details on the ultra-thin iPhone 17 Air in that leak.

design

Typically, there will be two separate iPhone models, the iPhone 17 Pro and iPhone 17 Pro Max. Apple increased the size of the Pro lineup last year, and we expect those same screen sizes. The iPhone 17 Pro measures 6.3 inches, while the iPhone 17 Pro Max measures 6.9 inches. The overall size won’t change, but rumors suggest we could see some “significant” design updates, especially on the rear of the phone.

Apple could eliminate the titanium frame it has used for the past few years and instead transition back to aluminum. The iPhone 17 Pro models could have an aluminum frame with a half-glass and half-aluminum back instead of all glass. The half-and-half design would improve durability on the aluminum top while still allowing for wireless charging on the glass bottom.

While some rumors say the iPhone 17 Pro will have a two-tone design with a camera bump that’s different from the rest of the device, one analyst says the camera area will be the same as the rest of the iPhone, the same as the iPhone 16 models. The iPhone 17 Pro will likely be thicker to accommodate a larger battery, coming in at 8.725mm thick, up from 8.25mm.

Rumors suggest that Apple may redesign the camera bump. Instead of a square bump, Apple is going with a larger “rectangular” camera bump made of aluminum instead of glass. A rectangular camera bump would be a major design change and suggests the camera’s lenses would be arranged horizontally.

The iPhone 17 Pro and Pro Max are expected to enable a new “horizontal camera layout” and may be equipped with a wider rectangular camera bump, which is very different from the existing square camera island design.

Some sources claim that the camera area is an “elongated oval” with three lenses, which may be arranged horizontally or in a triangular pattern, which looks more futuristic. However, another source said that the camera design will not change much and will continue the existing style. Apparently, Apple is still in the testing stage of multiple solutions.

This “horizontal camera module” has also raised questions in the industry about spatial video shooting. In current models, spatial video relies on two vertically aligned cameras (wide-angle and ultra-wide-angle) to shoot stereoscopic images to simulate the horizontal distance between human eyes. If the iPhone 17 Pro adopts a horizontal layout, it may affect the spatial video shooting effect in the horizontal screen state, unless Apple is also developing new spatial video technology to match this change.

Previously leaked CAD renderings and 3D printed models have hinted at this possibility, including the structure of the extra-large rectangular camera area on the back of the iPhone 17 Pro. The leaked iPhone 17 Pro case also confirms this detail, with a whole horizontal cutout on the back to accommodate a wider camera module.

It is said that the iPhone 17 Pro body will also adopt a “half glass + half aluminum alloy” structure. Apple may retain the glass panel in the logo area to maintain the MagSafe wireless charging function, while the rest of the device will be changed to a more impact-resistant metal material. Compared with the current large-area glass back panel, this structure is more practical in improving the durability of the entire machine.

In addition, some renderings show that the flash and LiDAR sensor have been moved to a more “abnormal” position, away from the main lens. The purpose of this atypical layout is currently unclear, and there is speculation that it may reserve space for subsequent functions or modules.

Judging from the information that has been exposed so far, the iPhone 17 Pro will bring a major change in camera module, material structure and overall industrial design. If it finally comes true, this will be the most recognizable back cover change since the iPhone X.

color

According to the latest news, the iPhone 17 Pro series may introduce a new color scheme inspired by the “Sky Blue” on the M4 version of the MacBook Air. It is said that this color has become a “hot candidate” among multiple design prototypes within Apple and is likely to become the main new color of the 17th generation Pro series.

This “Sky Blue” is slightly different from the previous blue tones. Compared with the “Sierra Blue” on the iPhone 13 Pro, the overall tone is softer and brighter. Its appearance under different light is also more varied-close to silver at certain angles, with a light metallic feel, but not too bright, which is in line with Apple’s pursuit of “low saturation, high texture” color matching in recent years.

Display

According to multiple sources, Apple is expected to introduce 120Hz refresh rate panels in all iPhone 17 products in 2025, which means that high refresh rate will no longer be the exclusive privilege of Pro models. However, this change still has differences in details.

A reliable whistleblower pointed out that although the iPhone 17 and iPhone 17 Air will also be upgraded to 120Hz displays, they will not be equipped with full ProMotion adaptive refresh technology, that is, the refresh rate cannot be dynamically reduced to 1Hz. This means that although the regular iPhone 17 has smoother scrolling animations and smoother UI operations, it still does not support the “always-on display” function.

As for the Pro series, it is expected that the LTPO adaptive panel will still be retained, and it will continue to support 1Hz~120Hz dynamic refresh rate, taking into account both smooth experience and low-power display.

Regarding other improvements in display technology, it is reported that Apple is testing a new scratch-resistant and anti-reflective coating process for the iPhone 17 Pro model, with the aim of improving outdoor visibility and reducing the problem of screen scratches. However, it is reported that Apple encountered a process bottleneck in the mass production stage, and the yield and coating efficiency are difficult to meet the needs of mass production, so the plan may be postponed.

As for the future of the “Smart Island”, there are also differences among different reports. Analysts said that Apple is trying to miniaturize the components required for Face ID and introduce Metalens (metal lens) technology for the first time, which is expected to reduce the opening of the front camera module, thereby reducing the area of ​​the Smart Island. However, another well-known analyst believes that the iPhone 17 series will not have significant changes in the Smart Island and will continue the current design size.

A series chip memory + heat dissipation improvement

According to multiple sources, the iPhone 17 Pro series will debut Apple’s next-generation flagship processor, the A19 Pro chip. The chip is built on TSMC’s optimized N3P 3nm process and is expected to bring a slight improvement in power consumption control and operating efficiency. Compared with the A18 Pro, it focuses more on sustained performance at the practical level.

In addition to chip upgrades, there are also significant changes in memory. The iPhone 17 Pro and iPhone 17 Air are expected to come standard with 12GB of RAM, a generational improvement over the 8GB of the iPhone 16 Pro series.

This change will help the stability of multi-tasking, background resident and heavy-load applications, and will improve the actual usage experience, especially for Pro-level users.

To cope with the higher heat generated by the A19 Pro chip, Apple is reportedly testing a cooling system to improve the thermal management capabilities of the entire device. This solution quickly spreads heat over a larger area to avoid performance reduction due to overheating. The copper heat plate assembly currently used in the test prototype has entered the small-scale verification stage in early June, and whether it will be finally mass-produced remains to be confirmed.

camera

All four 2025 iPhone models are rumored to have upgraded 24-megapixel front-facing cameras, which are an improvement over the 16-megapixel front-facing cameras on the iPhone 12 models. The cameras will significantly improve image quality and allow for more cropping without losing quality.

Apple is expected to upgrade the telephoto lens to 48 megapixels, which is a significant improvement over the current 12-megapixel telephoto lens. The iPhone 17 Pro models will be the first iPhones with three 48-megapixel lenses, as the wide and ultra-wide lenses have already been upgraded to 48 megapixels.

One leaker suggests the new 48-megapixel telephoto lens will offer 3.5x optical zoom (85mm equivalent) instead of the currently available 5x zoom (120mm equivalent). 3.5x optical zoom would be better suited for portraits, and the higher resolution would allow for more cropping, allowing Apple to simulate a 5x optical zoom as well. Apple already uses this approach for the fused camera in the iPhone 16 and 16 Plus, as the wide lens enables a 2x digital crop, which is the only “telephoto” option for Apple’s more affordable iPhones.

The iPhone 17 Pro could support shooting 8K video, instead of the current 4K recording maximum. The iPhone 17 Pro model may offer dual video recording, a feature that will allow users to record videos using the front and rear cameras at the same time. Some apps already support this feature, which is useful for content creators, but the built-in camera does not.

The iPhone 17 Pro’s wide camera may have a mechanical aperture, allowing users to adjust the size of the aperture to adjust the amount of light reaching the lens. Current iPhones have fixed apertures, but a variable aperture would allow more control over depth of field.

Battery and Charging

It has been revealed that the iPhone 17 Pro series may continue to use the new battery bonding structure that Apple first introduced on the iPhone 16 and 16 Plus. This technology allows the battery adhesive to be loosened through low-voltage current, greatly simplifying the battery replacement process and improving repairability. This also means that in the future, battery replacement may no longer require complex disassembly, which is a positive improvement to the repair experience.

At the same time, the thickness of the iPhone 17 Pro is said to be slightly increased, mainly to accommodate a larger battery, which may bring further improvement in overall battery life performance.

In terms of charging functions, Apple seems to be quietly upgrading. It is reported that the iPhone 17 Pro is internally testing a reverse wireless charging function that supports up to 7.5W output, allowing users to power accessories such as AirPods or Apple Watch through their phones. Although some iPhones have previously been able to power these devices at 4.5W through the USB-C interface, they do not support wireless reverse charging.

In addition, leaked MagSafe charger images from the accessories side show that Apple is introducing support for the Qi 2.2 wireless charging standard for the iPhone 17 series. Qi 2.2 can theoretically achieve a wireless charging rate of up to 50W, but whether the actual power will be fully open remains to be determined. Apple has always adopted a conservative strategy for charging speed, and it is expected that power will still be limited in the early stages to ensure device temperature control and battery life.

In terms of wired charging, the iPhone 17 series as a whole is expected to maintain a maximum charging power limit of 35W, which is consistent with the current iPhone 15 Pro series, and there is no sign of a significant increase.

Summarize

Based on the current revelations from all parties, the iPhone 17 Pro series is undoubtedly the biggest step forward in design and technology that Apple has taken in recent years. From the new material structure, rectangular horizontal camera module, to the higher-specification A19 chip, 12GB memory and vapor chamber cooling system, these latest 10 revelations are no longer “minor repairs”. The shooting capability has further leaped forward, and the 48MP lens, variable aperture and 8K video recording of the entire series also make it a step further for professional creators.

At the same time, the Pro series will also launch a new sky blue color scheme for the first time, using a more recognizable visual language; in terms of battery and charging, it has also achieved all-round enhancements from structure, battery life to reverse wireless functions.

Although some functions and designs have not yet been finalized, it is certain that the iPhone 17 Pro will become another key turning point for Apple in industrial design, imaging system, performance and user experience. Whether you are a heavy user pursuing the ultimate hardware or a person who is looking forward to a brand new appearance, this year’s iPhone is worth a closer look.
