I am not sure we have the same concept of "easier on the eyes". Whether a photon comes from a backlight or from a pixel, it is a photon. Likewise, pentile pixel arrangement does make edges of fonts and things a bit "fuzzy" so points lost on that.
You have had several OLED phones and base your power consumption estimate how? Different phones are different. I know OLED displaying white screen uses more power than an LCD. Fact.
Look, it is fine, you like OLED. OLED is a newer technology and is absolutely great... but not for everything. OLED is fantastic for television. It isn't strictly best for mobile.
Based on several other phones that were LCD including several iPhones that never lasted as long as any of my OLEDs. I will tell you there is a difference between real life experience than a spec sheet. I really think you just need to give OLED a chance before knocking it out especially since more companies are going that route. Funny, how OLED is touted for its power savings over LCD by every company that implements it. FACT!
