Apple recently released iOS 15.4, which features Face ID unlock while wearing a mask. In addition, this firmware fixed some vulnerabilities from the previous version.
However, now it turned out that after updating the smartphone, the autonomy of the device suffers greatly. More and more users are reporting this. For example, the charge of the iPhone 13 Pro Max lasts only half a day after the update, and the iPhone 11 versions are discharged from 80% in two hours of active use.
Those who have already moved to iOS 15.4 should wait for the reaction and another Apple update. This is not a new situation, the company happens from time to time. Those who have not yet updated and value the charge of their smartphone should not rush to update their gadget.
