What is a nifty little feature modern gadgets have lost? (lemmy.world)

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

If you turn off other aid features

What?

it won’t use more battery than a notification led.

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.

    aid what?

    Typo: aod feature. Always on display.

    If the screen has 60hz or higher refresh, I’m pretty sure it will.

    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.
