Since jumping on the public beta about a month ago I have felt that despite a few hiccups the battery life has been about as expected for a beta. In terms of % of battery load I have noticed that iMessage is always at or near the top. It currently stands at 31% with no other apps over 10%. Is this the product of the upgraded features in iOS 10? Has anyone else noticed this? I am also running iOS 9 on my iPad Pro and it has a cellular connection. I wonder on the times that I don't switch that to airplane mode if the constant syncing has any connection to battery life.
