iOS 17.0.3 just launched, and Apple promises it “addresses an issue that may cause iPhone to run warmer than expected.” This is a well-publicized problem with iPhone 15 models.
It also might increase the battery life of previous iOS handsets.
Fix for hot iPhone 15 problem released
Shortly after the new iPhone 15 models reached customers, user began complaining that the devices get hot. Apple acknowledged the problem and promised a fix.
That fix is called iOS 17.0.3. The release notes make that clear:
“This update provides important bug fixes, security updates, and addresses an issue that may cause iPhone to run warmer than expected.”
It’s not known what other bugs are taken care of by iOS 17.0.3, but a couple of security fixes are included too, according to Apple.
Might increase iOS 17 battery life
Tests show that iOS 17 decreases the battery life of a wide range of older iPhone models. It’s possible iOS 17.0.3 takes care of the problem.
A hot iPhone is a symptom of power being wasted. And wasted power reduces battery life. If the iOS 17 bug that Apple just took care of affects more than the iPhone 15 series, then previous devices could see longer times before needing to recharge.
We won’t know for sure until tests can be done on handsets running the new patch.
An iPadOS patch released, too
The iPhone and iPad operating systems are close enough together that an update to one brings an update to the other. So it’s no surprise that iPadOS 17.0.3 also debuted Wednesday.
The release notes for it mention nothing about heat, just saying, “This update provides important bug fixes and security updates and is recommended for all users.”
How to install iOS 17.0.3 and iPadOS 17.0.3
Hot iPhone users can install the new iOS version directly by opening the Settings app and going to General > Software Update. Alternatively, you can update your device by connecting it to a Mac (or to a PC running iTunes). The same goes for iPad users and the iPadOS patch.
