For me it’s the notification light you used to find on older phones, was particularly good to know if your phone was charged without picking it up

Nowadays most phones have OLED screens, which can easily replicate the function of the notification LED with the “always on” feature.
Yet there are often warnings that even with OLED AOD eats a lot of battery, not so with a notification LED.
The absolute newest OLED that can do 1Hz refresh are better. But that doesn't change that the removal of the notification LED was detrimental to the functionality of the smartphone.
OLED AoD eats a lot of battery because there's still quite a lot of information(and thus, pixels turned on) shown on the AoD. A single pixel blinking on and off would at most use the same power as a dedicated notification led.
Someone else posted an app that gives the feature back. If you turn off other aid features and just use the app it won't use more battery than a notification led.
What?
If the screen has 60hz or higher refresh, I'm pretty sure it will. The screen itself may not use much, but the DAC will still use power.
I haven't seen this actually tested, but many claim the difference in battery life is noticeable. I don't think it matters much what app you use, many phones come with an AOD app, and I seriously doubt a third party app is better.
Typo: aod feature. Always on display.
It's supposed to drop down to 1hz. The CPU refreshing a pixel of an OLED screen or a notification led is the same power usage. That is even if you have a notification led, the CPU could still be stuck refreshing it at 60 hz.
AH ok that makes a lot more sense. ;) As I understand it, it's only the newest top displays that can go down to 1 Hz. Or maybe it's just when in use they can't for some reason. I find the 1Hz capability to be extremely cool, so it would be great if it's a more general feature of AOD.
I really can't. I did it all. It just doesn't come near the tiny lil LED shining bright.
And yet they don't
