Looking at all the features that older phones uses to have compared to newer ones, I never hear anyone talk about the removal of the notification LED. I personally really liked that feature, being able to see if I got an email, a text or missed a call without turning on my phone was awesome. My Samsung note 8 had this feature, but to my knowledge, newer phones (in the major companies anyway) have abandoned this feature. Did everyone else unanimously agree they don’t care for this feature?
Maybe older models were a lot less efficient with always on display, but I just checked for my Pixel 8 Pro and the ambient display was <1% battery usage.
Don’t think an S20+ is that old. I turned it on full time just after I posted that last comment, just on the edge of the screen. Low brightness. 3.5% of the battery use in 5 hours.
