iOS 9 feature? Screen shouldnt light up in pocket or face down?

[Ggvfvgbffbf]

So one of the power saving features of iOS 9 is meant to be that your phone won't fire up the screen when you get a notification -if the phone is face down or in your pocket.

So just checked this out by checking my phone when notifications came thru to my iPad. Whether it's in my pocket or in a completely immersive folio style case the screen is still lighting...

Anyone else?

Which iPhone is it?

My iPhone 5 still lights up when facedown. Disappointment.

If it's face down or in your pocket how do you know that it's lighting up or not?

Cover the proximity sensor with your hand, hold the phone upside down and have someone send you a text.

AFAIK this is for phones with motion coprocessor only, so 5S and up.

Which iPhone is it?

I'm using a 6.

To answer the question about how I know. I've got my iPhone face down on a table. When a mundane notification comes thru on my iPad I'll very quickly flip my phone up.

Trust me, the display was lit up before I flipped the phone over.

I don't recall that this is meant to work when in pocket but glad to be proven wrong.

Continuing with the assumption that it only works when facedown, it might not be the simple case that it will work when it's roughly upside down, dark and something is close but also more precisely:
a) within a degree or two of flat, and/or
b) not moving at all

These extra measures would help rule out some other cases where the screen is not actually obscured and therefore might still be useful to light up the screen. These measures would perhaps explain why you are still seeing the screen light up.

I think the best way to test would be on a glass table with some card under the ambient light sensor.

That's because it's for iPhone 5s or later. It uses the M7/M8/M9 coprosessor.

I'm not sure you have to turn it over, as soon as it senses movement I'm guessing it would probably light up.

(just wanted to add, another good way to test is with the bottom half of your iPhone hanging off the edge of a table- be careful it doesn't drop of course.

Can confirm this works on my 6- screen did not light up. However covering the top bezel with my palm and holding with screen facing down still resulted in the screen turning on- so I think small movement or an imperfect flat angle will cause you to fail to trick it into thinking it's facedown on a table.)

It would make sense that the coprocessor is required, I guess. I'll refrain from a planned-obselescence comment.

how much battery do you think this saves?

Huh. You have a point there.
