Apple iOS 15.4.1 Release: Should You Upgrade? – Forbes

Apple iOS 15.4.1 has landed and it is a surprise on almost every level: timing, fixes and a critical security patch. So should you upgrade? Here’s everything you need to know.
Tip: bookmark this page because I will keep it up to date if/when new problems are found. I will deliver my final verdict in a week.
04/08 Update: Final Verdict Below
Apple iOS 15
Apple iOS 15.4.1 and iPadOS 15.4.1 have been released for all iOS 15-compatible devices, this means the iPhone 6S (2015) and newer and iPad Mini 4 (2015) and newer. There are now serious concerns around the auto-update process, so the best method is to trigger it manually by navigating to Settings > General > Software Update. If you are running newer beta software (see ‘The Road Ahead’ section at the end), you must unenroll your device before the update will appear.
Note: this guide is not focused on older iOS updates or iPadOS, but I will touch upon pertinent issues in these guides.
Jailbreakers, there is no news here. Unc0ver and checkra1n have been stumped by iOS 15 and, with a critical security patch this update (details below), it is time to change your priorities.
For everyone else, the first two days suggest Apple has another solid release on their hands. Complaints to @AppleSupport on Twitter are minimal, while Apple Support Communities and Reddit are quiet. I have seen isolated reports of battery drain in iOS 15.4.1, but most users suggest there have been tangible improvements here (see next section). Long term complaints (Bluetooth stability, storage consumption) also appear to be significantly reduced following this release.
All-in-all, the signs are promising, though I will continue to monitor this as more users upgrade.
Apple’s official iOS 15.4.1 release notes read as follows:
“This update includes the following bug fixes for your iPhone: Battery may drain more quickly than expected after updating to iOS 15.4 Braille devices may become unresponsive while navigating text or displaying an alert Made for iPhone hearing devices may lose connection within some third-party apps”
Apple’s confirmation of a battery drain issue in iOS 15.4.1 is a surprise. Every iOS update brings complaints of battery drain (typically down to reindexing, which lasts 24-48h after updating) and Apple rarely acknowledges any issues. Moreover, complaints following the release of iOS 15.4.1 didn’t seem any higher than usual. Either way, Apple has seen and tweaked something and all attempts to improve battery consumption are welcome.
But the biggest news in this release is security. The iOS 15.4.1 security page reveals the update contains a patch for a new ‘Zero-Day’ vulnerability and Apple confirms it “is aware of a report that this issue may have been actively exploited”. This is the most dangerous type of security vulnerability.
Out of the gate, iOS 15.4.1 looks like a very solid update and it is a very important one too due to the zero-day vulnerability in iOS 15.4. Combine this with battery improvements and the vast majority of users should navigate to Settings > General > Software Update to make sure they get the update ASAP.
For the most hesitant, bookmark this guide. I will continue to update it with any relevant flaws or features I find and you will receive my final verdict here in one week.
04/08 Final Verdict – one week on from release, I have seen some isolated complaints about touch screen lag, auto-brightness going too dim in low light and the battery drain fix has not worked for everyone. That said, these complaints are few and far between. So, given the severity of the security flaw which iOS 15.4.1 patches, my advice is to upgrade.
Note: iOS 15.5 beta 1 has also started beta testing. It will bring several new features, with the primary changes currently coming to Apple Wallet. These include new Request and Send buttons for payment, UI changes and an ‘Apple Cash’ rebrand. I expect more features to arrive before it is released.
At the time of publication, Apple has not released a new iOS 15 beta though I would expect the first beta of iOS 15.5 to appear next week. Another ‘minor point’ update (iOS 15.4.2) is likely before that arrives as Apple looks to squash any remaining bugs. That said, iOS 15 is now a mature release which is some accomplishment after its dumpster fire launch.
