What methods are people using to keep screen alive without killing battery

I thought about displaying a gif of sparse star field and then using a ui interaction to touch the screen every 30 seconds.

Any other ideas?

If you have the OLED display ok, but if it's LCD the battery consumption doesn't decrease even if the image is black.
If you want to keep your phone unlocked, you can use the Secure Settings action but it requires an external app and the device rooted

What an insightful response!
Thanks so much for this!
I had no idea!

I want to keep my approaches widely adoptable so one of the tech requirements of my solutions is to do it without root. So I guess I'll see if my phone screen is OLED and start testing out how long is my battery life with the screen on perpetually. I wonder how it will degrade my phone life or if those screens last a long time.

Second comment here...

I looked up my phone:
The Galaxy S20 FE is the perfect device for fluid scrolling or watching a video, thanks to its 6.5-inch[6] Infinity-O Super AMOLED screen with a super smooth 120Hz refresh rate.

Sounds like I've got OLED so maybe dark screen can save some power?

Yes, because in OLED screens each pixel is like a light bulb, when it shows black the light bulb is off. While in LCD screens the pixels are like holes with variable aperture that let more or less light through, which is produced by LEDs that are always on when the screen is active (very trivial explanation...)
