The iPhone SE iOS 11.3 update is a milestone upgrade with a long list of changes. It’s an important update for your iPhone SE, but it could cause major problems if you aren’t careful.
Apple’s pushed thirteenth iOS 11 update to the iPhone SE. Unlike its predecessor (iOS 11.2.6), the iOS 11.3 update comes with a mix of new features, security patches, bug fixes, tweaks, and enhancements. iOS 11.2.6 was a much smaller maintenance release.
If your iPhone SE is currently running iOS 11.2.6, you get the shortest list of changes. If you’re currently running iOS 10 or an older version of iOS 11, your iOS 11.3 update will be much larger due to the features and fixes from the iOS updates you skipped. They’re baked into your upgrade.
We’re having a pretty good experience on the newest version of iOS 11, but some iPhone SE users are reporting issues with battery life, connectivity, performance, first and third-party apps.
You can’t predict exactly how the iOS 11.3 update will treat your device so you’ll want to be careful, especially if you’re moving your device to iOS 11 for the first time.
Our iPhone SE iOS 11.3 update walkthrough goes over some of these problems and provides some fixes to those that can’t wait for Apple’s next update.
Our walkthrough also goes over the key features that you’ll get when you upgrade to iOS 11 and it also provides you with some information about Apple’s plans for the future.
We’ve been using the iOS 11.3 update on the iPhone SE for an extended period time and we want to start off with a quick look at its performance.
