7 most common issues users are facing with the iPhone 15 series: possible causes and fixes

Every time Apple launches its new iPhones, they become the talk of the town for quite some time. This time too, the online discourse is largely around the new features of the iPhone 15 series. That said, these phones are not without their share of challenges. They have been on sale for a week or so and users have been already reporting a spectrum of issues. Notably, the issues are largely with the iPhone 15 Pros rather than the vanilla iPhone 15 lineup.

A list of iPhone 15 issues 


One of the most common iPhone 15 issues making rounds online is overheating. Many users have shared their experiences online including Ian Zelbo of 9to5Mac. Android Authority‘s test also backs the heating problem. In intensive tasks, the temps were going up to 40 degrees Celsius, which is uncomfortably hot to hold. Apple says this is an iOS issue and will be fixed in an upcoming update.

Users are facing iPhone 15 heating issues during high-end gaming, Facetime calls, and 4K video recording.  

This seems to be happening mostly when the iPhone is being fast-charged. Either the user feels it or sees a warning, “Charging was on hold due to iPhone temperature”.

Now, this could be because a fresh iPhone undergoes lots of activities, both foreground and background in the initial few days or hours. If it happens during this period, we think you need not worry. You can do a quick Google or YouTube search for the iPhone settings to change and that will help you turn off unnecessary trackers and activities.

However, if it persists, it could be a deeper problem with the design choices made by Apple for the new iPhone 15 models. Reputed Apple analyst Ming-Chi Kuo reckons it is not a fault with TSMC’s 3nm manufacturing process. Rather, he thinks Apple has compromised heat dissipation design within the new iPhones.

Battery drain

Another battery issue with the iPhone 15 Pro is that it’s draining quickly for some users. But like we said already, the first time you start using an iPhone, it takes a lot of setting up and a lot of trackers and background activities must be running.

Moreover, lithium-ion batteries may take some charge cycles to adjust to your use case. So, give it some time before jumping to any conclusion.

Not everyone is experiencing the same. You would get to see some amazing runtimes from the new iPhones on various battery life tests on YouTube.

Battery swelling

The iPhone 15 Pro is not just heating up, it is also swelling up for some users, probably because of bottled-up heat inside. 


As a result of overheating, the iPhone 15 Pro Max is allegedly getting throttled. This was found by YouTuber Chris from TechTablets channel. He has shared this findings below:

It could be that the super powerful chips on these iPhones are generating a lot of heat and the system tries to control it through throttling.


Possibly related to the heating and throttling are the lags. These may not be deal breakers so to speak, but it would definitely be annoying to see the occasional or even one-off jitters on a new iPhone.  

Startup freeze at Apple logo

Can someone clarify what’s going on with the iPhone 15 setup bug?

Some users who were trying to transfer data at the time of the iPhone 15 setup process were faced with a boot loop at the Apple logo screen. Apple has rolled out the iOS 17.0.2 update to fix this bug. You must not skip this update. Just download it when prompted at the time of the new iPhone setup. 

In case you are still stuck in the boot loop, follow this guide from Apple to reset the device and set it up normally.

Breaks easy

iPhone 15 Pro Max’s back glass shattered in JerryRigEverything’s durability test with just his hands. As part of his test, he bent the iPhone and it broke in seconds. He wonders if it has to do with the tensile strength differences between the Titanium and Aluminum components used in the chassis. Meanwhile, the iPhone 15 Pro, iPhone 15, and iPhone 15 Plus survived the same tests with flying colours.

Other quality control issues

There are also several one-off reports of the new iPhone 15s having display misalignment, scratches on the screen, temporary discolouration of the chassis, and green tint on the display.

The issues may be few and far between but they are popping up nonetheless. Such posts get coverage and attract eyeballs but don’t let them cloud your judgement. We urge you to take stock of more than one or two incidents and see if Apple has fixed the previously reported issues by now.
