We have already seen a speed test video of iOS 10.3.3 vs iOS 10.3.2 and now we have another video, this one test the battery life between the two operating systems.
In the video below we get to see the iPhone 5, iPhone 5S, iPhone 6 and iPhone 6S. The test is run first on all four devices with iOS 10.3.2.
The four handsets are then all upgraded to iOS 10.3.3 and the battery tests are run again. The tests are run using Geekbench.
As we can see from iOS 10.3.3 gets less battery life on the iPhone 5, iPhone 5S and the iPhone 6 and more battery life on the iPhone 6S.
