The media visited the Brazilian Apple Mall. On the iPhone 15 checkout page, the part number ended with “BR/A”. According to local regulations in Brazil, this number means that it was assembled and produced in Brazil. Note: If the product is imported for sale in Brazil, the product label will be “BE/A” or “BZ/A”.

According to information displayed on Apple’s Brazil page, the models assembled in Brazil are limited to the 6.1-inch iPhone 15 standard version, while the iPhone 15 Plus and two iPhone 15 Pro models are still imported.

Brazil imposes high taxes on imported products, so some companies invest in assembling products in Brazil to reduce tax payments.

One user on the General Motors Truck Forum said their iPhone 15 Pro Max worked “flawlessly” on a 2022 Chevrolet Silverado 2500 High Country until they updated the device to iOS 17.1. After the update, their phone only charges for about “5 to 10 seconds” and then stops charging.

Other iPhone 15 users have had the same complaint on several vehicles made by General Motors, including the 2023 Chevrolet Bolt EUV, 2023 Chevrolet Traverse, 2024 Buick Encore GX Avenir, and Cadillac XT6, among others. Most users are finding difficulty charging their iPhone 15 after updating it to iOS 17.1. At the same time, users said that models such as iPhone 14 Pro Max and iPhone 15 that have not been updated to iOS 17.1 can still charge normally in the car.

“My iPhone 12 Pro Max works perfectly (every time) in my 23 Chevy Traverse,” one user said on Reddit. “About 6 weeks ago I switched to an iPhone 15 Pro Max and it just worked like other reviews described: it stopped charging after a few seconds and opening or closing the case had the same result.”

“We are aware of this issue and are investigating,” GM spokesman Stu Fowle said in a statement. “We have nothing to confirm at this time.”

This issue is somewhat different from the one affecting BMW’s iPhone 15. In this case, users discovered that wirelessly charging their iPhone 15 in a BMW disabled the NFC chip inside the phone, preventing them from using Apple Pay and BMW’s Digital Key feature. Apple fixed this issue in an update in iOS 17.1.1, but unfortunately, it appears there’s another charging issue Apple needs to address.

iPhone 15/Plus screen:

 Advantages: DXOMARK evaluates the screen brightness of this phone as good, with good legibility under most tested light conditions, and compared with the previous iPhone digital series, the colors of photos are more vivid; there is almost no frame loss in video playback appears, and motion blur is well optimized.

 Disadvantages: The 60Hz screen refresh rate is slightly less smooth when sliding and playing games, and the mid-tone contrast in HDR10 videos is low, and the overall tone in photos and videos is orange, which affects color rendering and skin tone presentation to a certain extent.

iPhone 15 has an audio score of 141 points, ranking 5th in DXOMARK’s global high-end smartphone screen rankings and 15th overall. The iPhone 15 Plus audio score is the same as the iPhone 15.

iPhone 15/Plus audio:

 Pros: In terms of playback, the device excels in multiple attributes, with good overall playback quality, deep extension of the low frequencies, and good dynamics and spatial performance. In terms of recording, the sound quality is good, especially when recording louder scenes such as concerts; sound artifacts are handled well, although wind noise control still needs some fine-tuning, but its performance is pretty good.

 Disadvantages: When playing audio at maximum volume, the device has certain distortion and compression, and the stereo sound in the music application is inverted like all iPhone devices; when recording, the mid-frequency performance is greatly affected by the usage scenario, and may occur Canned or nasal sounds; the main vocal content is easily obscured by background noise, and audio focus performance is poor.

In addition, DXOMARK also announced that the iPhone 15 Plus has an imaging score of 145 points, ranking tied for 12th place with Apple iPhone 15 in the global imaging rankings, and ranking first in the high-end model category.

DXOMARK reviews iPhone 15 Plus When using the HDR screen to browse content shot by the device, the image contrast is vivid and the brightness performance is good; whether it is photo shooting or video recording, its exposure and color performance are particularly good. In portrait mode, the device can accurately estimate depth of field and retain details, and in bright environments, the color rendering and skin tone restoration of photos and videos also appear natural and comfortable.

The disadvantage is that the zoom capabilities of the iPhone 15 Plus still lag behind the Pro series models; in low-light environments, some details are missing and there is more noise in photos and videos.

According to foreign technology media 9to5Mac, in the Xcode 15.1 Beta released by Apple today, three internal frameworks, FactoryOTALogger, FactoryOTANetworkUtils and FactoryOTAWifiUtils, were discovered in the iOS 17.2 Beta 1 SDK, which can implement wireless OTA firmware updates through special external devices.

In a previous report, the relevant scenarios were shared as follows:

The first batch of iPhone 15 models shipped out of the factory came with iOS 17 built-in, but when users purchased it, iOS 17.0.1 and even later new versions of the system had already been released. This means that users may have to spend time updating the software after opening the box of their new iPhone.

Regarding this move, Mark Gurman revealed that Apple has developed a special cushion-shaped device on which retail stores can place unopened iPhones. Then the system can wirelessly connect to and wake up the iPhone, and then Automatically download and install the latest version of iOS to complete the software update and finally shut down.

The report states that this feature is now clearly marked as an internal feature, which can install the latest iOS updates on sealed iPhone devices to avoid first-time issues similar to the iPhone 15 migration failure.

Since the launch of the iPhone 15, Apple has been getting feedback from users that the new model is experiencing serious screen burn-in issues. Some have speculated that this could be a hardware issue with the OLED display, and now Apple has fixed the burn-in issue through software.

While most of the reports of the problem are coming from “iPhone 15” users, some users of the iPhone 13 Pro and iPhone 12 Pro devices are also seeing similar issues, which is probably why Apple’s release notes don’t specifically mention the “iPhone 15”. iPhone 15″ specifically in Apple’s release notes.

Using a microscope, iFixit was able to get a closer look at the iPhone’s casing, adhesives and display, down to individual pixels. There are enlarged views of everything from the battery connectors to the magnets inside the Taptic Engine.

The iPhone 15 is very similar to the iPhone 14 as the design has not changed. However, it is noticed that the new phone has a larger 48-megapixel camera. iFixit confirmed that the camera is actually different from the 48-megapixel camera in the iPhone 15 Pro Max. The iPhone 15’s camera is about 22% smaller, which means that The camera doesn’t perform as well as the iPhone 15 Pro Max’s camera in low-light conditions.

In the Reddit community, many iPhone 15 model users commented that after turning up the volume, the audio will suffer from distortion and sound breakage, and the sound breakage of the earpiece speaker is the most obvious.

One user reported: “I discovered this problem after unboxing the iPhone 15 Pro Max. After raising the sound to the highest level, the speaker would make a rattling sound and it sounded like liquid inside. In addition, when playing music, the volume exceeded This happens in 80% of cases too”.

“Based on my experience, the audio seems to rattle or crackle in certain videos or within certain frequency ranges,” another user reported.

TikTok anchor Milesabovetech reported that he encountered this problem. Apple replaced it with new phones for free twice, but the problem still exists. Other iPhone 15 users on Reddit have also reported asking Apple for a replacement – and the issue persists on the new device.

The latest iPhone 15 / Plus series of phones may also have the same problem, according to the media, which said that the iPhone 15 / Plus phones use cheaper batteries that have only about 600 charge cycles.

Apple’s reason for adopting a cheaper battery for the series of phones may be that the relevant models of phones do not support fast charging, the phone’s battery loss in a single charge is less, Apple cut costs in this regard, and ultimately used a battery with only 600 cycles.

Apple is cutting costs on batteries because the company has established an extensive and reliable supply chain and retail network that allows it to quickly replace batteries for users, the media said.

The foreign media also quoted a blogger on the X platform, RGcloudS, a long post, to explain

The relevant content is as follows:

Do you know why the battery life of iPhone 14 and 15 series drops faster?


It's because it uses cheaper battery cells, similar to third-party parts that average only 600± charge cycles.


Yes, it's a high-density battery. The original iPhone 12 Pro Max battery has a capacity of 3687 milliamp hours (mAh), while the third-party iPhone 12 Pro Max battery has a capacity of 4350 milliamp hours (mAh).


The battery capacity is the same or similar on the iPhone 13, 14, and 15, but the battery in the iPhone 13 is a high-density and high-quality cell.


When it comes to Li-ion batteries, most phones, especially flagship models, use batteries with 800 charge cycles. some of BBK Group's phones, such as the Find X, vivo X, realme GT 240W and OPPO, use more advanced self-healing battery cells with 1,600 charge cycles.


Batteries with 500-600 charge cycles are typically used in high-performance products such as mobile power supplies that support up to 300 watts of power transfer, vacuum cleaners, blenders or handheld/portable devices that support a minimum of 100 W. 18650 and 21700 cells are commonly used.


What about larger devices / electric vehicles? They use batteries with 800 charge cycles.


The best high performance battery exists in the Vespa Elettrica electric motorcycle made by LG Chem, which has 1000 charge cycles.


The problem is that the iPhone is not a high performance (100+ watts) product, so 600 charge cycles is unacceptable. In order to make significant upgrades without raising the price, Apple had to cut costs, which is another factor besides the drop in NAND prices that explains why Apple has been able to keep prices stable.


Interestingly, recent iPhone batteries use recycled cobalt as the cathode material, and repurposing recycled cobalt to battery grade actually costs the same or more, and is more expensive than buying a high-quality battery with 800+ charge cycles.


And most of Apple's revenue comes from services. So if certain parts of a product are easily replaceable, it will lead to more problems.


As long as it doesn't involve the display and other important parts that affect daily use, it's not a big problem.


I don't understand environmental protection,

As part of his iPhone 15 Pro review, Marques Brownless (aka MKBHD) took the time to discuss battery usage and overheating, confirming that he did experience the latter, “but not in the way I expected.”

Recalling using his iPhone to record a golf tournament in hot weather, MKBHD says the iPhone worked fine. However, on the flight back, the YouTube sensation was running Spotify and browsing Instagram at the same time, only to find that the iPhone heated up and rapidly drained about 5% of its power in a five-minute span.

Brownless provided a screenshot of the battery section of the settings. The image shows that Instagram is the app with the highest battery usage, with Spotify coming in second. Bug fixes and app updates could solve these issues in the short term.

Farouk, a tech reviewer at iPhonedo, found a similar situation with Instagram on the iPhone 15 Pro Max. He confirmed this claim by monitoring iPhone 14 Pro, iPhone 14 Pro Max, and iPad Pro comparison tests on devices updated to iOS 17 and iPadOS 17 and running Instagram.

In the tests, Instagram on the iPhone 15 Pro Max did “almost nothing” while running, and consumed about 10% of the battery in a ten-minute period.

While iPhoneDo’s tests seem to have found the problem, namely Instagram on iOS 17, it’s not an issue that affects all users. The YouTuber admitted that the issue only affects “a small number of people” and is not a more widespread problem.

Instagram and parent company Meta have yet to respond to the new claims.
