iOS 11.3 brings new user-facing features for assessing your iPhone battery’s health and chemical age, including manually disabling Apple’s controversial CPU throttling that kicks in as soon as you experience your first unexpected shutdown over a worn-out battery.
In addition to headline-grabbing features like performance throttling, iOS 11.3 packs in a bunch of little things, under-the-hood tweaks and fixes that make this another recommended software update for your iPhone, iPad and iPod touch.
Perhaps the two most eagerly anticipated iPhone and iPad features—Messages in iCloud and AirPlay 2—are apparently not ready for prime time yet because they’re nowhere to be seen in the official iOS 11.3 changelog.
Apple on Friday made the sixth beta of the upcoming iOS 11.3 update available to developers. Registered developers can install the new beta from Apple’s developer center, or by using the OTA updating mechanism in iOS.
Apple on Monday made the fifth betas of iOS 11.3, tvOS 11.3 and macOS High Sierra 10.13.4 available to developers. Registered developers can install the new betas from Apple’s developer center, or by using each platform’s OTA updating mechanism.
