Apple rolled out the iOS 17.2.1 software update last month to deliver “important bug fixes.” While rolling out the update, this is what Apple said in most countries. However, soon after the update was released, the Cupertino-based tech giant said that the update “addresses an issue that can cause the battery to drain faster under certain conditions,” in both China and Japan.Now, a new report claims that iOS 17.2.1 did more than fix a battery-draining bug.
How the latest update is affecting users
According to a report by BGR, the latest update has also broken iPhone connectivity. The report claims that some users took to Apple’s Support Community Discussions platform to complain that their iPhones were no longer able to connect with their cellular provider after their devices were updated to iOS 17.2.1.
One iPhone user the update released to fix the battery from draining was causing their battery to drain. He wrote: “After updating my iPhone last night to 17.2.1 I can no longer connect to my network provider. Tried the resets and still it does not work! Very frustrating. Trusted Apple and iPhone for years, now not so sure.”
Another user on the same site said: “After installing this update I’m facing heating and battery draining issues on my iPhone 15. Do we have any solution to this ?”
This suggests that some iPhone 15 series handsets are also suffering from the “thermal issues” and are overheating once again.
Temporary workarounds to fix the issues
The report also suggest some workaround which have been mentioned by iPhone users on the Apple Support Community Discussions website:

Users can also try installing the iOS 17.3 beta version which has also been rolled out. Since the iOS 17.3 public beta release was released before iOS 17.2.1, installing this version may rid users of the connectivity bug.
How to download the latest iOS 17.3 public beta version
Firstly, go to beta.apple.com. Tap the beta sign-up button and sign in using your Apple ID and password. Then go to Settings > General > Software Update and tap on the Beta Updates box near the top of the display. Select iOS 17 Public Beta and you will receive the latest iOS 17.3 public beta version to install.
However, before installing the iOS 17.3 public beta, users should remember that beta releases are unstable and they need to stay in the beta program until the final version of iOS 17.3 is released.
