Re: OLED power usage?
Yes, if it's AMOLED. No, if it's just plain OLED (OLED still uses a backlight which remains on no matter whether the screen is showing black or not). In real-world usage studies I've seen, if you are using AMOLED and keeping everything as close to true black as possible while still being able to read it, the power savings is around 15-20%.
