Last week released iOS 15.4.1 in public version. It was then specified by the developer that this new edition came to solve a problem apparently caused by the previous one and causing a energy consumption too high. Even though several betas had been tested upstream, precisely to avoid this kind of inconvenience.
However, in the latest video from the YouTube channel iAppleBytes these are very different figures that are noted by benchmark. Many iPhones are thus lagging behind, such as the iPhone XR which goes from a score of 3,362 to 3,188 points when going from iOS 15.4 to iOS 15.4.1 or the iPhone 13 (5,070 vs 4,790 points) . Others, such as the iPhone 12 or the iPhone 7, however, seem to have gained in autonomy but they only represent less than half of the mobiles tested. More precisely, five are in the red while four are doing better than before.
Which devices are affected?
These measurements having been carried out within a certain framework, it cannot be certain that they accurately represent the current situation. The numbers are still pretty worrying though, and owners of devices whose endurance might be at half-mast would do better to think twice before buying them. update.
It is therefore a question of the iPhone XR, the iPhone 13 but also the second generation iPhone SE, the iPhone 11 and the first iPhone SE. The most recent has not been tested, just like the iPhone 13 Pro and iPhone 13 Pro Max.
No effective solution yet
Fortunately for those who are still on iOS 15.4, it is apparently still possible to revert to iOS 13.3.1 but that’s only for a while. Indeed, Apple has a habit of blocking this manipulation after a few days, as was also the case when this version had definitively replaced iOS 15.3 a little earlier.
Otherwise, the publisher is probably already thinking about a fix. Usually these are deployed fairly quickly, but you can always try to speed things up. in reporting the bug directly to Apple via the dedicated form. You will be asked to enter your email address to send it.
