    Just purchased an iPhone 7. Jet black 128gb. I'm wondering if leaving hey Siri on is a battery hog. It's the only extra feature I have going 24/7 and I noticed right off the bat that my battery life isn't all that great. Is she sucking my battery dry?

    That's easy to determine. Disable Hey Siri for a day and see for yourself.

    The advantages of Hey Siri are much more convenient for me than those 15 extra minutes of usage I'd get without it, so I leave mine on.

    I've never thought that to be an issue with my battery at all. But as suggested try it both ways and see if you notice any difference. As it is my 7 has the best battery life of just about any phone I've used.

    Technically your microphone is constantly on and listening for specific words like 'hey Siri' so it can start actually recording and responding to your questions. I don't think this would cause big battery drain though.

    I would agree with Tartarus and say try disabling Siri and see if battery life improves. Just remember, battery life will improve over the next couple days.

    The first few days are always a little worse than normal since the phone is doing a lot of syncing and learning what you like doing most. 😃

    I'm thinking the Lift to wake is a battery hog, it's like the screen is always on. I still like it though, if anything just to check the time BUT I have read that turning ON "reduce motion" saves some battery life because it stops the screen animations when closing apps or double clicking the home button......instead of animation it just snaps directly to the screen instead. I have been testing it for a while and I think it helps a little.

    I would say that both are extra drain, but how much I wouldn't know. I have both disabled.

    This. To me, lift to wake can be useful but it's not a big deal to tap the home button so it's off.

    Agreed. I don't mind hitting a button to wake the device. In fact, I think I may prefer to have that control.
