Title says all. Among conventional calls, FaceTime audio calls and iMessage texting, which one would drain an iPhone's battery fastest?

EDIT - This is assuming a conversation is taking place with very few pauses in the middle.

I'd rank them like this, from highest consumption to least.

Conventional call
FaceTime audio

and waaaaay further down

iMessaging

But wouldn't iMessage be the fastest because the screen is always on?

Maybe if you were having a 2 hour long continous conversation..I was going by normal use of sending a message, then hitting the sleep button to turn off the screen in between messages.

If you're talking about the first situation, then they'd probably be about the same.

Sorry, I should've mentioned that this is assuming it's a conversation with very few pauses or breaks.

If that is the case, taking iMessage aside, how big of a difference would there be in battery drain in the other two calling?

As long as you didn't have screen brightness on 100% then I'd still probably say iMessage would take the least battery. Best way to test though would be to just give them a try.

Charge battery to 100% and make sure all other apps are closed. Have a 30 minute conventional phone call. See how much battery has drained.

Charge to 100%, close all apps, have 30 minute FaceTime Audio call, repeat.

And then repeat for iMessage.

There's a lot of variables that could go into it, screen brightness being the biggest for iMessage.

Just use whichever best fits your situation.
