One of the most persistent complaints against the iPhone is its battery life. It is a common complaint seen on any help sites or in support blogs. Many reasons are given for this—from apps to overheated batteries—and many solutions are given through blogs and websites.
But this time, Apple itself has decided to release the fix for this problem since many people started to complain about the battery drain after updating to iOS and iPadOS 15.4. Apple responded by releasing another update of 15.4.1. It not only fixes battery drain bugs but also fixes some accessibility bugs and improves security.
The problem seems widespread enough to make Apple respond through their Apple Support Twitter account that it was “normal for your apps and features to need to adjust up to 48 hours after an update” to anyone who complained about the battery drain. The Twitter response was released earlier last month. But since the issue persisted for weeks since the release of iOS 15.4, they released the new update.
The iOS15.4 update introduced many features such as the ability to unlock iPhone with the mask on, Live text (where a text in the photo will be digitized and can access it while drafting an email or writing a note or reminders). It also added a new voice for Siri, increased security for Apple Pay, 100 new emojis, and improvements to Safari.
They upgraded Apple’s AirTag and Find My app features and added new security features. Another problem the new update brought in was that the braille devices became unresponsive while navigating text or when an alert was displayed.
Another problem the new update brought in was iPhone hearing devices losing connection to third-party apps. The new update will also fix these problems. Another issue it will improve is the AppleAVD which could allow an app to arbitrary executive codes with kernel privileges. This security defect affected iOS and macOS devices and was addressed with improved input validation with the new update.
The second flaw is in the Intel Graphics Driver, where an expert hacker can read kernel memory. Apple released another security update macOS Monterey 12.3.1, separately to solve this issue. The company did not give out any details or indicators of compromise to help its users detect signs of malicious activity.
The update is released by the Cupertino-based company and has a size of 313.2 MB. The update is available on all devices, but certain features will only be activated on iPhones that are neither 12 nor above devices. Even though it is updated to solve these issues, certain security features and bug fixtures will increase the security and efficiency of the device.
Even Apple has asked the users to update as soon as possible to avoid exploitation of it and an indefinite period of no updating is not good for the device.
To update the iPhone, go to Settings > General > Software Update. To update the Mac, go to System Preferences > Software Update.
