I know there was a lot of talk about the Environmental Sound Measurement impacting the battery life in the beginning but has anyone tested it lately and have any idea how much, if at all it impacts the battery life?

I’m after views from anyone who has actually tested rather than the assumption that anything turned on will use battery.
