iOS 17.0.3 Addresses iPhone 15 Overheating Issue and Security Vulnerabilities

Since its release several weeks ago, reports about the iPhone 15 overheating have accumulated. Speculation first pointed the finger of blame at the iPhone 15’s new titanium case, but Apple categorically denied that, issuing a statement saying:

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. 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.

My iPhone 15 Pro became too hot to keep in a pocket comfortably for a few hours after initial setup as it downloaded apps and photos, but once it was done, it ran at normal temperatures. I’ve seen that with previous iPhones as well.

Apple has now released iOS 17.0.3 to address its mistake, and John Gruber reports that an update to Instagram resolves an egregious bug that caused it to consume 1% of battery life per minute while idle. Such poor programming is yet another reason to avoid Instagram.

iOS 17.0.3 and its companion iPadOS 17.0.3 also fix a pair of security vulnerabilities, one of which has been exploited in the wild. Given the zero-day vulnerability and the potential for iPhone overheating, I recommend updating soon.

Comments About iOS 17.0.3 Addresses iPhone 15 Overheating Issue and Security Vulnerabilities

Notable Replies

  1. My iPad updated to 17.0.3 overnight. No issues so far but it gave the message that Siri now responds to “Siri” and “Hey Siri”. I had to go to Settings to change it back to just “Hey Siri”. irritating that Apple makes these type of changes as defaults.

  2. iOS 17.0.3 loaded fine on my iPhone 13 mini. No problems as far as I can tell at this time. Also, I’ve seen comments online that my problem with missing custom text tones will likely be fixed in iOS 17.1, but it’s still buggy in its current beta form.

  3. Was this an upgrade from 17.0.2 or from something older?

    I saw this change when upgrading from 16.x to 17.0.1. Which I expected, because this was a publicized new feature. It didn’t reset my “Hey Siri” configuration after the subsequent upgrades (17.0.2 and 17.0.3).

  4. Yes - probably occurred going from 16.x to 17.x but I didn’t notice in the few days before I installed 17.0.3. I am currently updating another iPad to 17.0.3 so will check the Siri setting when it is finished.

  5. I didn’t know the heating problem with iOS 17 affected iPads or any iPhones EXCEPT the iPhone 15s. When I updated my iDevices the other day I was only given the option of going to 16.7.

  6. My wife had the same thing…she said she didn’t have 17 available but the update to 16.7 was there and then the 17 one was there after it was done. Since the 17 one was down at the bottom in Software Update…she said she might have missed it but doesn’t think so.

  7. iOS 17.03 also corrected a CarPlay connection issue with my 2018&19 Honda Accords and my iPhones 12 & 13Pro. iOS 16.6 or 16.7 caused my CarPlay to stop working. 17.03 restored the connection!
