Apple recently released its iOS 15.4 update, which included much-needed support for unlocking an iPhone while wearing a mask. However, many users found that their phones’ batteries were draining more quickly than usual after the update was installed. One user claimed that his iPhone battery was 5% depleted in less than 10 minutes, which prompted many to vent their frustrations on social media. Another user with an iPhone 11 reported that after the update, the battery drains to zero by noon from an all-day battery life of all-day battery life.
Users of both the iPhone 12 and the iPhone 13 reported similar battery issues, including some who were using the iPhone 13 Pro and the iPhone 13 Pro Max, both of which are supposed to have excellent battery life.
In the past, Apple has been reluctant to confirm such issues, but Apple Support responded to a tweet about battery drain problems. The official Apple Support handle, for all purposes, acknowledged the problem and then provided an explanation/solution for it in their response.
“Thank you for getting in touch! We’d be happy to assist you in any way we can. It’s normal for your apps and features to take a few days to adjust to an update. To assist you further, we’ll need you to reach out to us via direct message (DM) if the problem persists after that time.
To be clear, this isn’t much better than the IT department telling you to restart your device to fix whatever problems you’re having. Apple has basically told all iPhone users who are experiencing battery issues that such drops in battery life are normal and that battery life might take a day or two to return to its previous levels.
“Maximizing Battery Life and Lifespan” is the title of a support page that Apple also posted a link to.
A list of ways that iPhone users can extend the life of their devices’ batteries can be found on this page, with one of the first recommendations being ironically “Update to the latest software.”
Improved battery life can be achieved by using features such as Auto-Brightness, Low Power Mode, and others.
