Apple recently released iOS 12.3.1 to the public as a slight bug fix release. Apple doesn’t always give us a full rundown of what goes into these updates though, and some do have a history of reducing an iPhone’s battery performance.

To that end the folks at iAppleBytes have made a point of testing new releases against previous ones, just to see how things pan out. They’ve been at it again, too.

The new video uses an iPhone 5s, iPhone 6, iPhone 6s, iPhone 7, and an iPhone 8 for testing purposes. Geekbench’s better test was initially run with iOS 12.3 installed with the same test then repeated once the phones had bene updated to iOS 12.3.1.

You can check the full 14-minute video out if you want to get the full outcome, but the upshot is that the update doesn’t make a great deal of difference on devices as a whole, although some did see an improvement. Importantly, none saw a reduction in maximum battery time once they were updated to iOS 12.3.1, which is arguably the biggest concern for those using older devices.

Apple’s attention will now turn to iOS 13 which will be shown off at WWDC on June 3rd. The initial beta release will also be made available to developers if previous years are any indication, and we’ll be installing it to see how it works. We’ll also be covering WWDC and all that comes out of it as well.

It’s sure to be quite the event for the Apple phone, tablet, watch, and computer user.
