Apple released iOS 18 a few weeks back, and the update brings a plethora of front-facing additions to the table, including new customization tools for the Home Screen. However, not every major update is pleasant, as it can hide bugs under the hood, which might have an impact on the battery life of your iPhone. If you are experiencing faster-than-usual battery drain issues on your iPhone after updating to iOS 18, then you are not alone.
If your iPhone is draining more battery life than usual after the iOS 18 update, you should give it a few more days
Each major upgrade from Apple has its pros and cons, and while the pros outweigh the cons, some can hinder your daily usage. You might have observed that your iPhone is draining more battery life after updating to iOS 18, and it is not an issue, per se, but a mild inconvenience at best, considering the update has an underlying bug.
There are various reasons why the battery life of your iPhone is draining faster than usual after the iOS 18 update. For one, some apps have not yet been updated with feature support for iOS 18 and all of its new features. This could cause optimization issues under the hood, and the result is that your battery life will take a hit. Other than this, if you are running a beta version of iOS 18, possibly iOS 18.1, with Apple Intelligence support, you might be encountering various bugs as the build is not in its final stage, and the company is working with developers to fix the issues.
Lastly, even if it has been a few days since the release of iOS 18, Apple says that you should wait some more for the update to completely sit. Apple's support page states:
"If you notice that your battery life has decreased after updating your iPhone, wait a few days and then check again. Even though you can use your iPhone immediately after an update, certain tasks related to the update continue in the background and might affect battery life and thermal performance."
This is one of the reasons why many users are experiencing battery drain issues on the iPhone. The company is working on a subsequent update for the iPhone, iOS 18.0.1, which will fix most of the underlying bugs that could be consuming more battery than usual. We would advise you to wait a few more days before filing a complaint to Apple. We will keep you updated on the latest so be sure to keep an eye out.
