Two weeks after the deployment of iOS 15.4, Apple is launching a first patch intended to solve the autonomy problems encountered by certain users, as well as to put an end to a backdoor access allowing the takeover of an iPhone.

In mid-March, Apple posted a major update bringing many new features to the iPhone. The famous version iOS 15.4 included in particular a facial unlocking compatible with the wearing of the mask. But as often, this upgrade came with some difficulties that Apple intends to address through a patch.
Autonomy increased, iPhone better protected
The iOS 15.4.1 update, which is quite light at less than 400 MB, aims to fix two major problems that appeared with the deployment of iOS 15.4. The first is at the level of autonomy, strongly affected by the update dating from mid-March. Many users have complained of a too rapid drop in the battery level of their iPhone, a shame when the 13 series is one of the most enduring smartphones – Pro models in mind. An iPhone 13 Pro Max usually able to last a day and a half could end its day with less than 20% battery. A surge in consumption that Apple had tried to explain in a tweet.
Thanks for reaching out! We’ll be happy to help. It’s normal for your apps and features to need to adjust up to 48 hours after an update.
Let’s have you reach out to us in a DM if this is still an issue after that time so we can help you look into this further.

This new update is designed to correct this shortcoming, but it will be necessary to wait a few days before having the first feedback from users.
iOS 15.4.1 also allows Apple to patch a critical flaw providing access to iPhones. The American company explains that clever little guys have managed, via an application, to execute code with “kernel privileges”, ie to make their way to the core of the smartphone. According to the firm, this flaw has been widely exploitedApple did not provide more details.
Small additional fixes
A bug involving Braille was present when reading text or broadcasting alerts. The latter could block the iPhone, preventing its operation. Connection errors have been fixed for hearing aids certified as “Made for iPhone” and some apps taking advantage of them.
Finally, this small update brings support for Business Essential, a new service aimed at small businesses launched only in the United States for the moment. Apple has not yet announced anything about a deployment on our side of the Atlantic. The service page is however available here.
