Why is wifi using almost 50% of my battery?

[acles003]

So this is pretty much a daily occurrence. I've tried wifi calling enabled and disabled. I can't figure out what is causing my wifi to eat up so much of my battery.

I've had an Android phone since 2009 so I'm not a noob to this, but I honestly cannot figure it out. I'm on T-Mobile if carrier matters for some reason.

A couple of things to try:

1. Turn off Smart Network Switch in the Wi-fi Advanced Settings.
2. Go to Settings>Privacy>Location>Improve Accuracy, and make sure Wi-fi Scanning is turned off.

Yep verified both are turned off.

Yep verified both are turned off.

Do you have wifi set to remain on when the phone is sleeping? That can kill battery as well.
