iOS 9.0.2 battery life is one of the main concerns of those who have done or want to update to the new version of the operating system in the following days, iOS 9.0.2 being launched on Wednesday by Apple.
In the past days since then I have tested iOS 9.0.2 battery life on the terminals I have at home and I can tell you that the face of iOS 9.0.1 there is no significant improvement though the company Apple Lossless Audio CODEC (ALAC), solved a multitude of user problems.
I already told you that iOS 9.0.2 has better performance than iOS 9.0.1, although the difference is minor, but this improvement is not "visible" in iOS 9.0.2 battery life so you don't have to expect an improvement for her because you won't see anything like that.
To be completely honest with you, I didn't even expect the battery life of iOS 9.0.2 to be better than iOS 9.0.1 battery life because only a week passed between the release of iOS 9.0.2 and iOS 9.0.1, so Apple did not have much time to make major improvements.
Having said that, the battery life of iOS 9.0.2 will be the same as in iOS 9.0.2, but slightly better than in iOS 9 and weaker than in iOS 8.4.1, so you have to choose carefully which versions of the system operating system run in your terminals.
