It has been almost a week since the iPhone 15 and iPhone 15 Pro arrived in the hands of early adopters. While most buyers have had no problems, many users have reported several issues with their new phones.

Some of these are undoubtedly more serious than others, but when you're paying $799 to $1,599 for a phone, it's not unreasonable to expect everything to be smooth sailing. Below are the current issues with the iPhone 15 and the likelihood that they will be corrected.

As we reported shortly after the iPhone 15 began shipping in September, some users experienced overheating of the iPhone 15 Pro and Pro Max, with one blogger recording a maximum temperature of 118°F. One blogger recorded a maximum temperature of 118°F. For some users, this happens during simple tasks such as scrolling through social media feeds or watching videos, but for others it seems to be related to charging.

We tested this phenomenon using infrared thermography. The worst temperature we recorded was 104.1°F, which was when charging and playing video simultaneously on the iPhone 15 Pro Max.

Initially, there seemed to be several factors at play here. First, the fact that the majority of those who filed complaints were using the iPhone 15 Pro, which seems to be related to the brand new A17 Pro chipset, but the fact that some iPhone 15 models also experienced overheating issues seems to rule out that possibility. And also, Apple reportedly decided to cut back on last year's A16 chipset due to fears of overheating.

Some have also speculated that the titanium alloy chassis may have something to do with it, but this would only explain the overheating of the iPhone 15 Pro models. Analyst Ming-Chi Kuo believes that this and subsequent thermal design compromises are related.

Apple, for its part, blamed the problem on software rather than hardware and released iOS 17.0.3 to fix the issue. Now that a software fix is available, the company plans to keep a close eye on whether reports of overheating continue.

Another issue specific to the iPhone 15 Pro and Pro Max titanium shell is how easily it collects fingerprints, as the following tweet neatly illustrates.

To make matters worse, some users say that fingerprints have discolored the titanium frame, which is a bit worrisome if you've spent hours agonizing over which iPhone 15 Pro color to get.

Apple states in its support documentation that the discoloration is temporary. "The oils in your skin may temporarily change the color of the outer band," the company writes.

"Wipe the iPhone with a soft, slightly damp, lint-free cloth and it will return to its original appearance."

There are also many question marks about the iPhone 15's durability, especially when compared to the previous generation. Not only are there reports of questionable build quality of the device in hand on the first day, but there are also questions about how well it will stand up to rough handling.

First, in a video by Sam Kohl of AppleTrack, the iPhone 15 Pro fails a series of uncomfortable drop tests. Except that the iPhone 14 Pro, tested at the same time, was relatively unscathed, which is nothing to be ashamed of given the heights involved.

Another set of data comes from smartphone torture specialist JerryRigEverything. He put an iPhone 15 Pro Max to the test and was not able to handle it well, cracking the back glass with just a little force from his thumb (7:20 in the video).

Curiously, the same did not apply to the regular 15 Pro (10:40 in the video), but you might still want to consider taking AppleCare Plus - or at least investing in one of the best iPhone 15 Pro cases.

One way to get around this altogether, of course, is to get a case. However, Apple's new-look FineWoven case has attracted a lot of criticism because of its premium $59 price. In short, it appears to be very vulnerable to scratches and stains.

Repair experts iFixIt literally put the case under the microscope to figure out what was going on. The good news is that small scratches don't damage the fibers, but they will never be restored.

"Scratching the surface doesn't actually break the yarn or damage the dye. Rather, the scratched fibers reflect light more erratically than a bundle of unscratched fibers, leaving visual marks." Since the thread itself is relatively soft, most pocket items can leave an impression."

And, "The threads themselves are not as soft as those of the fabrics themselves.

So, while it's good to be protected, don't expect it to stay in pristine shape for long. In fact, Parker Ortolani of Vox Media found that one Apple Store display model was distorted less than a day after being displayed.

Many of the buyers were switching from older iPhones, which suffered from a particularly nasty bug on the first day.

As we described at the time, some users (including Bloomberg's Mark Garman) got stuck in a boot loop when trying to transfer data from their existing iPhones.

Apple quickly issued a software update (iOS 17.0.2) to address this, but some users were not prompted to download it before running into problems. In their case, they solved the problem by connecting their new iPhone 15 to a PC or Mac with a cable and following a few simple steps.

"For me," Garman wrote, "this was not a hassle."

"But this is obviously not a very hot experience for consumers who have just gotten a new phone - and a particularly tricky undertaking for the uninitiated."

.

It is unclear how widespread this complaint is, but some users also complain about the performance of the new iPhone 15. At times, the following lagging or choppy animations occur.

The good news is that this is probably not related to the hardware itself, but to the software. Since all iPhone 15s come with iOS 17 preinstalled, it appears that Apple still needs to optimize it a bit.
