Above you can see detectable (under close scrutiny, ideal conditions) burn-in of my Nexus 6 screen after the following usage:

Only 8 weeks since I bought the phone

I'm reasonably sure that this was not present when I got the device because:

1 - it was "new" from Amazon in factory sealed box (although at a bargain price $299 for 64gb which makes me wonder slightly);

2 - inspected it pretty careully when I was reading about burn in shortly after I got my device;​

My screen on time on a typical day is probably 2-5 hours per day over that 8 weeks. (although probably 5-6 hours per day during the very first week!)

Brightness is always in auto with the slider in the middle. And I don't spend a lot of time outside with my screen on.

You can see that's pretty mild usage for a relatively short time. And yet many others are reporting they absolutely can't detect anything whatsoever even after a year of use. . I'm led to believe I'm an outlier.

So what is it that might make me more susceptible than the next guy?

The "easy" answer is device quality. And it might be the right answer, but what if there's something else.

I thought about what it is in my usage (which seems relatively mild) that might possibly cause this.

Then I realized the one thing that struck me odd about this phone. I noticed the screen is warm to my fingers if I use it while charging. I didn't meausre that temperature, but I did download GSAM about a month in and and set a battery temperature alarm at 110F. If I do mild surfing while charging, battery temperature gets up to 110F within a few minutes. I don't let it go above that now, and the screen feels relatively cool compared to how hot I used to let it get. So I'm going to guess that my battery temperature used to routinely get to 115 or 120F while I was using my phone while charging. And although they're not equal, when battery gets hot screen gets hot (again I could feel the heat).

Would heat affect amoled deterioration? We wouldn't think that at first because we normally associate the deterioration with simply being energized brightly over time. But what about being energized causes that deterioration. What if it's the localized heat at the pixel from that brightly energized pixel that causes the damage. In that case, anything else which makes the phone/screen run hotter overall will tend to enhance that local damage mechanism also.

Does my phone run hotter than average? I'm not sure, but since day 1 I've been using this funky case Uniform Supcase Beetle Hybrid Pro.. It's built like an otterbox.... thick and rugged. Up to 1/4" inch thick and surrounds the phone on back, all sides, and even wraps around to cover the front bezel. Imagine that wrapping is an insulator (like a blanket), it helps to keep the heat inside so the phone underneath the blankets is hotter than it otherwise would be.

Is that case why I'm different? I dunno, all I've got is one phone as a data point and a scenario that seems plausible to me.

I'm interested to know if any others have associated elevated temperatures or a thick case with enhanced susceptibility to burn-in . Or if you believe it may be related.

By the way, I have to add my perspective this is a minor and managable thing. I still love this phone. I'm just curious about why...

There are of course many threads on subject of N6 burn-in. The biggest one here:
