Hi, what phone do you have?
It sounds like you are describing Glance Screen, which can be turned off in the settings.

Here's the thing about Glance. It's not really battery intensive. If you are worried about battery there are much more productive avenues to explore.

However, Glance by default is "Always On" and you can mitigate that by use of the proximity sensor. When it is in your pocket, Glance gets shut off by the proximity sensor. Also if you get in the habit of laying your device face down when you set it on a surface, the proximity sensor will shut Glance off. This way it is there when you need to "Glance" at the details it provides and absent when you don't.

Also there are other options for how it will persist. Maybe explore those as well in the Glance settings.

Good Luck.

Although I marked another best answer, I'm with Robert (RumoredNow) on this one! It's quite light on battery, and there's other ways, as he suggests to handle it. Your drain is probably coming from elsewhere. Facebook or twitter maybe? Or a carrier app?

Not a proximity sensor but the camera's light sensor. I have Glance set to only display when I wave my hand over the phone (Peek mode) except when charging during the day (Night mode settings).

Question just struck me: If it is set to display when charging is it displaying when it is in your pocket or laid face down? (can't try this myself as my USB socket is broken and I only use a wireless charging stand)

If it is in your pocket it isn't charging, so no Glance will be off.
If you lay the phone face down (off charge) Glance will be off and if you turn it over it is still off for a moment before turning on.

You can have the phone plugged in and charging then put it in your pocked or face down. That is the scenario that I was hoping to be answered.

Plug in, lay it face up and place a glove or cloth over the top 1/3 of the screen. I'd test it myself, but the only W10M I have with Glance is boxed and ready to ship when it sells...

Just checked with my phone on WP 8.1 and it still displays Glance screen when I cover the proximity sensor. I don't know the behaviour on Windows 10.

I would try it myself, but as I said, my USB socket is broken.

Tested it on my Lumia 650. After covering the top 1/3 of the screen the time and date goes off.
Uncover the screen again and the time + date comes back.

It goes off of the proximity sensor, not the light sensor. When covered up it'll turn off, but it'll continue to function in a dark room.
