Does turning on VoLTE drain the battery more on the iPhone 6?

I have a 6+ and I feel like my battery is dropping faster ever since I turned in VoLTE, is this happening for anyone else or am I just imagining this?

What else do you have running? Did you turn off bluetooth,location services and background app refresh

Does anyone actually know if leaving Bluetooth on drains the battery? I thought Bluetooth 4.0 LE was supposed to not draw any power unless it has a connection.

I thought that was the whole point of LE.

Haven't noticed any excessive drains. My new iPhone 6 (4.7") lasts more than a day on a charge.

Bee running VoLTE all week, over 18 hours of voice calls using it and haven't noticed any discernible drain on the battery.

I had read somewhere that VoLTE actually draws less radio power than standard CDMA calls. But then there's CPU drain as well so I'm not entirely sure.

Random related question not worth starting a new thread for...When you guys selected use "Voice & Data" for LTE, how long did it take to get the check mark in the box? I'm on 5 minutes now of just the spinning loading wheel thing. When I select "off" or "data only" I get a check mark next to it instantly.

Mine did the same thing and took forever to actually check both the audio and data box. I just turned it off to see if battery would be better as it really sucked last night bad and over all hasn't been the greatest...

on the subject what exactly is voLTE and what is it used for

I googled it but it gave very techy answers
Basically, it allows you to use LTE (faster) data while you are talking on the phone. It also allows phone calls to take advantage of the additional bandwidth of the LTE connection to provide higher call (voice) quality.

It just means voice calls are over the LTE network.

This will allow for things like simultaneous voice and LTE data (not just 4G HSPA+ like before) and HD voice.

VoLTE on Verizon definitely sounds better than via cdma. Have made several calls with VoLTE turned on and sounds clearer. And calls to people who have phones that are also using VoLTE, were excellent.
