I have a Nexus 6p and so far battery life has been excellent in my usage. The phone lasts all day with ease but when I read Russel Holly's article on how you can get some more juice out of your battery I decided to remove the app and go with his approach (I still kept messenger)
While I cant claim to have notified any speed differences in the phone the battery usage is a lot better. I'm setting the phone to charge at least an hour or two later I'm the day than I used to which is quite impressive. I wonder what happened to Facebook's internal quest to have an amazing Android app where employees were using the app on Android devices and making improvements.
Anyone else seeing any difference ?
