Do this one thing to your OLED Android Phones and iPhone to make battery life last even much longer and Earth greener!

First of all, let’s start why smartphone manufacturers (Samsung, Apple and many more) these days choose to use OLED instead of LCD. And these are their reasons.

Starting with iPhone X, Apple has started using OLED screen on its iPhone. Apple move to OLED was deemed necessary because of mainly these 2 reasons:

1) battery technology doesn’t improve that much since the past decade and

2) the new iPhone and future coming iPhone come with everything screen, which literally translate to more battery power needed to light up the whole entire screen.

And because of OLED, not only newer and much better in technology when compared to LCD, but also it can show better sharper colors and when right color is chosen, it does save more battery life, so OLED was finally chosen by Apple as the current standard.

That’s also the reason, Samsung have been using its version of OLED screen called AMOLED since long time ago on all of its flagships, to compensate on the Android optimization that it can’t do very well – unlike Apple which does have full control on both hardware and software within one company so they know exactly where to optimize, Samsung is using Google Android which is not within their own control, they take whatever released by Google then merge with their enhancements, skinning, app store and their own apps.

The answer lies within the technology behind OLED screen. Unlike LCD screen which does requires backlight, OLED screen illuminates themselves without the need for additional extra backlight. What happen with black color and why it’s so special – it can save phone battery life – is because when OLED screen is showing black, the OLED is basically doesn’t show anything at all – it doesn’t light up anything, it’s just turned off the diodes and become deep black. And since it doesn’t light up anything thus resulting in better battery life since nothing gets consumed.
