Not really, aside from sometimes taking short breaks when the notification for maintenance comes up. I ignore it most of the time and do it a bit later.

Don’t mind at all! I’ve had my OLED for about 5 months now, and I use it a ton - about 60 hours a week combined across work and personal use.

Most decent OLEDs come with built-in protective features.

Mine notifies me that it’s due for “pixel refresh” (a 5 minute sequence where it looks like it’s off) every 4 hours of continuous use. I either let it do it and take a break, or it’ll just do it the next time I turn off my display.

There are other mechanics it uses to prolong its lifetime and prevent burn-in, e.g. my display is actually slightly larger physically than it’s reported resolution, and if you look at it very closely, it actually slowly moves the output from my PC around the extra space 1 pixel row/col at a time. So no UI elements will ever stay on the exact same pixel all the time.

I’ve never had to worry about burn in myself; I think the norm is that OLEDs largely take care of themselves now.
