iOS beta 11 2 was launched the other day by Apple and if you still had doubts about its installation because you didn't know what kind of autonomy the battery will have, well, maybe you can clarify now. In the video clip below you can see a comparison between the battery autonomy on iOS 11 beta 2 and beta 1, the first offering up to 35 minutes more for use.
The test is quite simple, with the same applications and functions running on two iPhone terminals that have iOS 11 beta 2 and iOS 11 beta 1 installed. The one with iOS 11 beta 1 stays faster without battery, while the iPhone terminal with iOS 11 beta 2 manages to work 35 minutes longer, so if you decide to install it, you will know what you will get.
In my experience, iOS 11 beta 2 consumes more battery than iOS 11 beta 1, but of course things can be different depending on what you do in terminals.
