I ask this question 1. because I'd really like to know whether or not there's a big difference between LCD and OLED panels; 2. there are a lot of other people out there who would like to know; 3. LTT could do a really great video that definitively answers the question on whether or not knock off iPhone OLED panels are close to as good as the iPhone's panel.

Hi all, first post here! I read an iFixit article which mentioned that iPhone X-series phones are compatible with both the original flexible OLED panels and aftermarket LCD screens. I don't understand how this is possible given that the two technologies use different waveforms, but anyway, this seems like an excellent opportunity to test out claims that OLED is better or worse for battery life compared to LCD. I keep hearing that OLED + dark themes use very little power. Yet every OLED device I've owned has had poorer battery life compared to LCD. A display panel engineer at Tianma told me that this is because of unoptimized software and not because of hardware. This Vice article mentioned that the knock-off LCD panels for the iPhone run hotter and use more power than OLED. Yet the same article mentioned that there was no performance difference between LCD and OLED. However, Anandtech's analysis of the iPhone XR's battery life put it significantly above its OLED stablemates in screen-on time. Ultimately, it's not clear to me which panel gets better battery life. Could this be an opportunity to put claims about OLED vs LCD battery life on iPhone replacement screens to the test? Can someone just drop in an LCD panel into an iPhone XS and measure screen on time in order to test the battery life of OLED vs LCD panels?
