Reports of severe instability began to emerge in several regions following the release of Apple’s latest software package for its mobile devices. The update identified as iOS 26.2.1, originally designed to integrate support for the new AirTags 2 and fix security vulnerabilities, ended up having the opposite effect. Proprietários of the brand’s smartphones are now facing a series of critical technical failures that compromise the daily use of the devices, transforming the update experience into a significant inconvenience.
Several technical support platforms and specialized forums have been flooded with complaints in the last few hours, describing a scenario where devices have become practically unusable. The expectation of improvements in interaction with trackers and system optimization was frustrated by errors that affect everything from energy management to biometric security protocols. The situation is made worse by the fact that the update was rolled out globally before the issues were contained, affecting millions of units.
Critical battery failures and overheating
Accelerated battery drainage appears as one of the main complaints among users affected by the new system. Dispositivos that previously held a charge for an entire day now require reconnection to the power source at intervals of less than six hours, even with moderate use. The problem appears to be linked to background processes that go into a loop, requiring constant CPU processing.
High temperatures were recorded on the back of the devices, specifically in the region close to the camera module and the central processor. Overheating occurs not only when performing heavy tasks such as gaming or video editing, but also when the cell phone is at rest or connected to Wi-Fi networks. Esse abnormal behavior suggests that the software is unable to manage the hardware efficiently, creating a cycle of energy consumption that can degrade the physical health of the components in the long term.
Face ID blocking and security risks
Another alarming problem involves the inoperability of the facial recognition system, the Face ID. Após the completion of the installation of iOS 26.2.1, the mechanism stops recognizing the owner’s face, forcing the manual entry of access codes to unlock the screen or authorize transactions. The failure is not corrected by restarting the device, indicating a profound error in the communication between the software and the TrueDepth camera.
Banking applications and digital wallets, which rely on biometric authentication to ensure fast and secure access, were directly impacted. The need to enter passwords in public places increases users’ vulnerability to malicious observers, reducing the layer of protection that the system should offer. Especialistas in digital security warn that, although it seems just an inconvenience, the flaw disables one of the device’s main defense barriers against unauthorized access.
The phantom storage bug
Users also noticed a drastic reduction in the space available on their iPhones’ internal memory after the update. The operating system began to miscategorize files, allocating up to 30 GB of data in the “Sistema Data” section, a space that cannot be managed or cleaned manually by the owner. Esse improper consumption prevents you from downloading new applications, capturing photos and videos, and even installing future patches.
Connectivity errors add to the list of problems, with constant drops in Wi-Fi signals and instability in 5G and 6G mobile networks. Pairing with accessories via Bluetooth, such as headphones and smart watches, experiences intermittent failures, randomly disconnecting devices during use. The sum of these factors has digitally isolated many devices, which, although connected, are unable to transmit data consistently.
Impact on iPhone 17 Pro Max and impossibility of downgrading
More advanced models in the line, specifically the iPhone 17 Pro Max, seem to suffer more intensely from the effects of the faulty update. Because they have high-performance processors, overheating in these devices is more pronounced, leading to automatic safety shutdowns more frequently. The irony lies in the fact that users who invested in the most expensive models to get the best experience are, at this moment, the most harmed by software instability.
Apple has stopped digitally signing previous versions of iOS, which means it is not possible to “downgrade” or return to the stable version of the system. Users find themselves stuck on version 26.2.1, without a technical escape route, awaiting an official fix. The company has not yet issued a detailed statement explaining the root cause of the failures, but the technical community expects the emergency release of iOS 26.2.2 to stem the crisis and restore device functionality.
