YouTuber and tech reviewer Marques Brownlee thinks he's worked out why people's iPhone 15s are overheating.
The brand spanking new iPhone 15 hit shelves last month, with Apple seeing an impressive 10 percent increase in sales compared to 2022's iPhone 14.
While's its Apple's best iPhone to date, some customers have experienced issues with the devices - overheating in particular.

One expert believes the issue could be down to the phone's lightweight structure, linking to 'the compromises made in the thermal system design to achieve a lighter weight'.
Elsewhere, customers have been urged not to use their Android USB-C chargers with the iPhone 15, which has seen Apple ditch its infamous lightening cable.
But Brownlee thinks otherwise and has speculated that some apps could be to blame.
“Two days ago, literally, I was just at a golf tournament in Florida it was like 100 degrees (about 38 degrees C) or something crazy like that," he shared in his video reviewing the new phone.
"And I'm outside with my phone at max brightness, with GPS going all day out in the sun, and it was fine, no problem, no overheating issues."
Despite the warmer Florida climate, it wasn't until Brownlee was on the plane home playing on his phone that his phone began to run hot.
He explained: "I’m on the airplane with my phone in Airplane mode, and I’ve got just like music playing with like music playing on Bluetooth with Spotify and like scrolling through Instagram, and for like five minutes, the phone just gets really hot and just blasts through like five percent battery."
Brownlee then went to investigate the battery section of his phone to find that Instagram was the top battery user, with Spotify coming in second and taking up 15 percent.
Other reviewers have found the same problem.
YouTuber iPhonedo said that 'once you start Instagram, it overheats the logic board very fast'.
In a bid to tackle this, he urged iPhone 15-users to enable low power mode to stop background apps constantly refreshing.
Elsewhere, Brownlee said that bug fixes and app updates could fix the issues in the short term.
Apple has since addressed the overheating issue and, as iPhonedo suggested, it may be down to background apps running.
The tech powerhouse said in a statement: "We have identified a few conditions which can cause iPhone to run warmer than expected.
“The device may feel warmer during the first few days after setting up or restoring the device because of increased background activity.”
The company went on: "We have also found a bug in iOS 17 that is impacting some users and will be addressed in a software update.
“Another issue involves some recent updates to third-party apps that are causing them to overload the system. We’re working with these app developers on fixes that are in the process of rolling out.”
It's thought that Apple plans on fixing the issue in a new iOS update.
