Why is iOS 18 Draining Battery So Fast?

Well, this is quite normal with the newly released iOS version no matter whether you’ve installed the beta build or a stable build. Once you shift from the previous software version to the new version, there are plenty of new improvements & features added that you can expect.

However, if you’re still encountering the same issue for a few days or weeks, don’t worry. Mostly, you may face battery-draining issues on your iPhone due to a lack of optimizations or some user settings that can be adjusted. But if your iPhone becomes older or the battery is almost dead, you’ll require a battery replacement for sure.
