Critical Face ID and battery flaws affect iPhone users after recent system update

Owners of the technology giant’s mobile devices face a complex scenario after installing the latest software package made available by the company. What was supposed to be a technical improvement aimed at compatibility with new accessories turned into a series of operational disruptions, with massive reports indicating the blocking of biometric security systems and excessive energy consumption, leaving thousands of consumers without immediate options for reverting to previous stable versions.

Severe impacts on biometric authentication and impossibility of downgrading

The update, technically identified as version 26.2.1, had the main objective of preparing the ecosystem for integration with the new AirTag 2. However, shortly after applying the firmware, users noticed anomalous behavior on their smartphones. The company has ceased digital signatures for the previous version of the system, which means that it is no longer possible to perform a technical downgrade, forcing those affected to remain with the unstable software until an official fix is ​​released.

The most alarming issue reported involves the complete failure of the Face ID. The facial recognition system, essential not only for unlocking the device, but also for validating banking transactions and accessing protected applications, stopped responding for a significant portion of the user base. The error does not appear to be related to the hardware, but rather to a software flaw that prevents correct communication with the depth sensors, forcing the manual entry of passwords for all operations, which represents a setback in convenience and security.

Accelerated battery drain and overheating

In addition to security issues, the energy performance of devices has suffered a considerable negative impact. Top-of-the-line Modelos, like the iPhone 17 Pro Max, which previously sustained charges for long periods, now present a drastic reduction in autonomy. Relatos indicate that devices need to be recharged multiple times a day, even with moderate use, suggesting that background processes are operating out of control.

Preliminary technical analysis indicates that the processor is continually being demanded by poorly executed optimization tasks after the update. Isso generates a vicious cycle of excessive heating and energy consumption, which not only frustrates the immediate usage experience, but can also accelerate the chemical degradation of the battery’s internal components in the long term, harming the resale value and useful life of the equipment.

Storage errors and unstable connections

Another critical point identified by the technical community involves internal space management. Usuários reported the disappearance of around 30 GB of storage, which was now occupied by unexplained “system data”. Mesmo After deleting heavy applications and personal media files, the space is not reclaimed, indicating an error in clearing cache files and installation logs that remain on the device as “ghost space”.

Connectivity was also compromised, affecting the stability of wireless networks. Complaints include:

– Frequent Quedas on Wi-Fi signal during video calls and streaming.

– Interrupções when downloading large files due to loss of data packets.

– Dificuldade in maintaining connection with smart accessories and other brand peripherals.

Expert recommendations and market positioning

Given the severity and variety of bugs found, technology experts and support forums recommend extreme caution. Para For those who have not yet updated to version 26.2.1, the unanimous advice is to wait. Installation must be postponed until the manufacturer publicly acknowledges the flaws and makes a corrected version available that guarantees data stability and security.

The situation generated a high volume of discussions on platforms such as Reddit and specialized portals, where dissatisfaction with software quality control is evident. Enquanto a definitive solution is not presented, the community is looking for palliative solutions, but the real fix depends exclusively on a new system patch that normalizes the functioning of the sensors, battery and storage management.
