Soon, you’ll be able to check the health of your iPhone’s battery life, thanks to an upcoming iOS update. You might recall that in December, some users complained that Apple was intentionally slowing down phones and shortening battery life through its iOS updates. This caused Apple to issue a statement saying that it wasn’t intentional, and explained that the slowness might be due to the “chemical age” of a battery. The tech company also said that the iOS 10.2.1 update launched a year ago was geared towards improving “power management during peak workloads to avoid unexpected shutdowns on iPhone 6, iPhone 6 Plus, iPhone 6s, iPhone 6s Plus, and iPhone SE,” but that these changes might have slowed down users’ phones (especially those with older batteries).

To remedy the situation, Apple had reduced the price of a battery replacement from $79 to $29 for anyone with an iPhone 6 or later. It also announced a new update that will enable users to look into the health of their iPhone’s battery—Apple’s CEO Tim Cook recently revealed more details on the update, which is expected to roll out in a few months.

In an interview with ABC News, Cook said that the new iOS update will not only give users more insight into the performance of their batteries (in turn helping them consider whether to purchase a replacement battery), but also enable them to disable the feature that slows down phones to preserve battery life. “We will tell somebody we’re slightly reducing, or we’re reducing your performance by some amount in order to not have an unexpected restart, and if you don’t want it, you can turn it off,” Cook said. Though Cook doesn’t recommend turning this feature off, as it could cause some unexpected shutdowns in phone with older batteries.
