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.
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.
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.
