Apple recently made iOS 14.3 available to the public and as ever, the same old questions are being asked – how does this impact battery life?

iAppleBytes has taken that question to heart, running benchmarks across a series of devices to see how things went down.

This video takes a number of iPhones so we can get a feel for new and older devices. The iPhone SE, iPhone 6S, iPhone 7, iPhone 8, iPhone XR, iPhone 11, and 2020 iPhone SE are all models that are in heavy use and this video gives us a good idea of how we can expect this update to impact battery life.

This video was shot 4 days after iOS 14.3 was installed, so it had time to settle in. I have seen many comments that it takes about a week for battery performance to optimize itself after an iOS update. I have always been skeptical of this statement as I have never personally had bad battery life right after I update. If I restore and download backup from iCloud well then that is another story. So I decided to run the battery test 5 days after I updated them. In those 5 days they were just idling with power connected. So let’s run the battery test again, and see if we will get some different results this time around.

We won’t spoil the video for you because it’s well worth taking in, but we’d always suggest installing iOS 14.3 regardless of the results of this test. It’s with it just for Apple Fitness+ alone.
