Apple releases iOS 15.4.1: solved excessive battery consumption

A couple of weeks after the release of iOS and iPadOS 15.4 , Apple has made publicly available iOS and iPadOS 15.4.1 (build 19E258), minor updates that mostly fix bugs and improve system security. Apple also released new tvOS and HomePod 15.4.1 (build 19L452) and macOS 12.3.1.

Regarding iOS 15.4.1, in particular, a bug that caused excessive battery consumption has been fixed. I also corrected a problem with Braille devices and “Made for iPhone” hearing aids.

The update includes the following iPhone bug fixes:

  • The battery could run out faster than expected following the update to iOS 15.4.
  • Braille devices might not respond correctly when browsing text or when displaying an alert.
  • Made for iPhone hearing aids could log out within some third party apps.

macOS 12.3.1 addresses an issue that could prevent an external USB-C or Thunderbolt monitor from turning on when connected to Mac mini (2018) as a secondary monitor, and an issue with Bluetooth devices, such as game controllers, that could disconnect from the Mac after playing audio through some Beats headphones.

As usual, the updates can be downloaded for free in over-the-air mode via the appropriate menu in the settings. It is also possible to update under the 5G network if the “allow more data” function has been activated in the cellular network settings.

For the update it is necessary to have at least 20% of residual charge or, better still, to keep the device connected to the mains during the update. Before proceeding with the update it is always advisable to have a backup made on iCloud or on a computer.

With iOS 15.4 and iPadOS 15.4, remember, several features have arrived. Among these, the Universal Control , which allows you to use a single keyboard and a single mouse to control multiple devices at a time on which you are logged in to your iCloud account, the ability to use Face ID with a protective mask on the iPhone 12 and above, even without having an Apple Watch for authentication, the possibility of inserting the Green Pass in the Wallet and support for Emoji 14 .

Apple Touch ID not coming back? iOS 15.4 reveals Apple is focusing on Face ID

Apple’s Touch ID, a security feature for the company’s iPhone models, may not return as the company focuses on improving its current Face ID feature. Since the release of the advanced Touch ID feature, the tech giant has started integrating it into its smartphones.

The first model to have this feature was the iPhone 5 in 2013. Then the iPhone 6 and other models followed. However, Touch ID integration was discontinued by Apple after the announcement of the iPhone X. Some consumers criticized the move since the company recently announced an under-display sensor, as reported by MacRumors.

At the time, the company said it was two years ahead of the competition, but five years after the launch of the iPhone X, it still looks like Apple was, at least, half a decade ahead of the competition. its competitors in facial recognition.

According to the latest report from 9To5Mac, the release of iOS 15.4, which is expected to roll out in the coming weeks, means the popular Touch ID will no longer be available .

Rumors about the removal of Touch ID began after the global COVID-19 pandemic began. Some consumers find this fingerprint recognition feature quite effective, as it works very easily and quickly. However, the bitten-apple giant is now considering using Face ID technology, as it is more secure than Touch ID technology. With Face ID, all you have to do is look at your iPhone screen. After that, it will open automatically.

Face ID is now more efficient
Apple’s Face ID still has some issues. One of them is its inaccuracy when the user wears masks. Remember that people around the world might still need to wear face coverings since the global pandemic can last for years until it is completely neutralized.

For this reason, Apple has come up with a simple solution to solve the problem of masks, which is to integrate the eye recognition function into Face ID . This new feature should be available as soon as iOS 15.4 is released. Thanks to this innovation, Apple consumers will soon be able to unlock their iPhones even when wearing a mask in public

That’s why you should urgently update your iPhone or Mac now

There are security gaps in many iPhones, iPads and Mac computers that are already being exploited by attackers. Users should update.

Apple has released updates for many iPhones and iPads, as well as Mac computers. Apple warns that this patches vulnerabilities that would otherwise make the devices vulnerable when visiting manipulated websites. According to a report, the vulnerabilities are already being exploited by attackers.

According to the information, iPhones from the 6s model, all iPad Pros, iPad Airs from the second generation, iPads from the fifth generation onwards, iPad Minis from the fourth generation and iPod Touch devices from the seventh generation are affected. You will receive an update to iOS 15.3.1, Mac computers one to macOS 12.2.1.

Apple has also announced that it wants to improve protection against unwanted surveillance by air tags. Together with Apple devices, these small tags form a Find My network. Items equipped with it can be searched and found over the network. However, air tags can also be misused for surveillance if they are secretly planted on people.

A look into the settings

If you have not yet been offered the iOS update, you should proceed as follows: Connect the iPhone or iPad to the charger, activate WLAN, go to “Settings/General/Software update” and then tap on “Download and install”. On Macs, you initiate the update in the Apple menu under “System Preferences/Software Update” by clicking on “Update Now”.

Apple has also announced that it wants to improve protection against unwanted surveillance by air tags. These small tags work with Apple devices to form a Find My network. Items equipped with it, from your pocket to a bunch of keys, can be searched for and found over the network.


However, air tags can also be misused for surveillance if they are secretly planted on people. To protect against possible tracking, iPhone users will receive a warning on the display if they are constantly carrying someone else’s Airtag around with them. In addition, air tags emit an alarm after 24 hours at the latest if they are permanently in the vicinity of a person who is not carrying an iPhone.

In addition, the future Airtag setup will also include a notice that tracking people without their consent is a criminal offense in many regions of the world.

Better warnings, louder alarms

In addition, the warnings should be improved: There are reports from users that security messages were issued because of Airpods in the vicinity, but not when there were Airtags in the area.

In addition, Apple says it is looking into further refining the localization of air tags, further improving the logic of the iPhone warnings because of air tags, connecting the iPhone warnings to the playing of an alarm tone on the air tag and its more precise localization, and changing the alarm tone and make it louder.

iOS 15.3.1 available for download. Don’t wait and update

IPhone users can now install the stable iOS 15.3.1 release. This is an urgent update that fixes the 0-day vulnerability giving unauthorized access to the phone. Installation requires less than 900 MB of data to be downloaded.

Apple has released an iOS and iPadOS update, which is crucial for security. Version 15.3.1 may come as a surprise (release 15.4 is already available in a trial version), but don’t hesitate to install it. The update includes a patch for the 0-day vulnerability marked as CVE-2022-22620 , which allows you to get to the data on the device.

According to Kaspersky , it is about incorrect management of dynamic memory in applications, which in practice leads to unauthorized access to data. The attack can be carried out from the level of a crafted website and ultimately lead to the execution of arbitrary code on an unpatched version of iOS. That is why the installation of the revised version of the system is so important.

The vulnerability was classified as Use-After-Free , which means unauthorized access to the theoretically freed memory by other applications. The idea is to use unremoved pointers that allow hackers to access data in memory that should not, by definition, be reachable, especially from other programs.
