Whenever Apple release a new version of its mobile OS one of the most scrutinized features has to be battery life. Apple tend to tell us that they have made a few tweaks in order for users to get a bit more battery life, but more often than not, this is not the case. It hasn’t taken long for people to start breaking the figures down in an iOS 8 vs. iOS 7.1.2 battery life comparison, one of which includes the iPad mini.
Looking at the chart in our second image you can see that the battery life on devices like the iPad mini running iOS 8 looks to be pretty much the same as iOS 7.1.2, although we can see that Apple’s smaller tablet (Retina mini) did not get as much from its battery running the new version of iOS.
However, we can also see in the chart that it was the original iPad mini that saw the most significant improvement. When running at a brightness of 200 NITS, the original iPad mini battery life running iOS 8 was 512 minutes of web browsing, compared to 474 minutes with iOS 7.1.2 installed.
It would seem that the new iPad mini Retina seems to struggle with getting the most out of iOS 8 in terms of battery life. However, Apple has given users the option to see what it is that drains the battery the most, and then take action if they wish to do so.
