I'm no developer so i have really no idea if this would work.
But, as this mobile is a AMOLED screen, each pixels are lighted up and so not much battery is drained on a black screen.
What if we could somehow make something when a new sms has not been read and screen turns of, a black screen like this appears
Is something like this possible?
pic example, could even be smaller or just 1 blinking pixel.

I think to display a message on screen the machine would need to be awake, so it would be using more power than with an led notification (afaik the device can normally go to sleep then).
Your idea would still save power over just showing the lock screen though because you are right that using fewer pixels would proportionally reduce power usage of the screen.
I guess the hardest part would be making the device appear off - It would need to ignore screen and button touches (except power).
Since we need to have the screen turned on to keep wifi/gps etc. running, and there are a few apps that would ideally run in the background with the screen off; to save battery power (and burn in?) it would be nice to have the AMOLED screen display just a black image.
Is there any app out there that just displays a black screen and maybe ignores all but a specific input?
At the moment I just zoom into a black image in the browser, but I can't put the phone in my pocket like that.
(I tried searching for this, but it was beyond my google-fu.)
You dont have to keep the screen on to run either my gps is always on and it neva disconnects also ive spent many nights going to sleep leaving my wifi connected and its neva disconnected either
Yup. If you haven't set WiFi to switch off after 15mins, it should carry on running.
By doing what you proposed, you'll decrease battery life drastically as you'd effectively be disabling the chips sleep mode by keeping it running 100%. With that, only the screen switches off and everything else including Android keeps running. Any application holding a partial awake lock can achieve this.
Lock delay; an app to control the default screen-lock options allows this.
For instance, if you set the initial screen timeout to 2 minutes but standby/lock to 10 minutes in the settings, the screen will switch off after 2mins idling, but the rest of the phone will still be running incl. WiFi/GPS. You can enable a lock/pattern or no lock at all where you press any key including menu/trackpad and it'll come back on in the same place you left it, without any lock. If the phone idles for 10mins, it'll activate the screen lock and place the phone in the standard sleep mode. The max delay you can set the latter to is 24 hours.
I wouldn't advise avoiding the sleep mode unless required in specific circumstances. Battery loss will be drastic; I found out unintentionally when activating this option at the beginning.

Thanks th3, that should do what I want. I don't intend to leave it unattended, it's just for when don't need the screen on while an app is doing something.

Hi guys. I received my Asus ZenWatch today from Best Buy. I attached a link to the video I made above that shows exactly what is happening. Once the screen enters battery saver mode (when screen always on is selected) and the minute hand advances, the clock shifts slightly. Does this happen with all ZenWatches, or is my watch slightly defective?

This is normal. It is to prevent image burn due to it being an amoled screen.
Notice there're like two types on how people use their Moto 360.
1) Ambient Mode: on - Tilt to wake screen: off
Can always see the watchface, backlight light up by touching/interaction.
2) Ambient Mode: off - Tilt to wake screen: on
Tilt will turn on the screen with backlight. Nothing if it doesn't.
Which are you? and why?

Unless my watch is defective and everything I've read is wrong, the face on a Moto360 will never always stay on, even when tilt to wake screen is off (I just tried it to confirm). Turning ambient mode on and tilt to wake screen off only makes it so you have to tilt to get the ambient mode screen.
But to answer the question, I'm neither. I have ambient mode on and tilt to wake screen on. I use this configuration because I want my watch to behave like a normal watch, and I don't want to have to touch it to see the time. I also want the screen to be on as much as possible because sometimes I hold my arm at an angle that isn't detected as a true "tilt" by the watch, and I want to be able to check the time despite this.
I have tilt to wake on and ambient off because I dont want touse more battery by keeping ambient on but I also want to be able to view the time without having to touch the screen or button.
TheSt33v: u had both of them on? How is the battery life?
I have them both OFF. I found out tilt to wake off extends my battery live tremendously. But I miht be a special case since I drive for living and the watch wakes up way too often.
I'd welcome some kind of "custom calibration" for cases like this and also it would be nice, if the screen would turn off IMMEDIATELY after you move the watch away from face.
I miss voted - I have both OFF (not on).
I like to tap or hit the button to see it. Otherwise it is on virtually all the time with my hands moving so much for work.
The the new app wod i kight turn mine into a boost gauge ....lol

I's fine. I charge it overnight, and it's usually 20-30% by the time I go to bed.
until today I used all OFF, but after seeing this post I decided to try with Ambient Mode ON and Tilt to wake OFF.. I'll post later on the battery life comparaison in my case. I'm surprised to see the screen go black when not moving the watch at all even with ambient mode ON.
It's clear, I don't like to use tilt to wake, because of the 1sec lag when I move my wrist to see the time, hate it to feel like I didn't move it correctly even if I did.
I just found out from this thread that it is possible to disable the tilt to wake up gesture. Thanks OP !
Stupidly, you can't find this in watch settings, only in Android Wear app's settings.
For me, tilt to wake up disabled and ambient mode enabled looks like the best combination and battery life seems to be the same or better than with the defaults (Ambient off and tilt to wake up on), especially when driving.

This is how I use mine. Ambient ON, Tilt OFF.
Tilt to wake lag's really bad.
Ambient ON means I can always see the time, like a real watch.
Talking to my watch is the daggiest thing in the world, so I would always touch it anyway to activate a task.
Battery:
40-30% left when I got to bed. Turn watch OFF.
Put on charge while I get ready for work in the morning. 95-85% 20 mins later when I leave.
Happy days....

I take it you still have to lift the watch to see the ambient mode (watchface) since the Moto 360 screen always goes off when you move your arm down?

Yep, but, when my arm is down, I cant see my watch anyway!
Even with an analogue watch I would need to point it toward my face to read it.
I find the moto360 is pretty good at guessing whether I'm looking or not. With my arm resting on the desk/keyboard as I type this, my ambient watchface is on and I can read it by glancing down, no watch movement required.
I'm pretty happy with the battery life I'm getting in this mode.

Agreed, I am liking the same settings on mine. Only 2 weeks with the watch so I still have to play some more but 11 hours into my watch use for the day and I am still at 59%!
I use tilt on and ambient off because i don't want use more battery when it not use.
Thanks for all the tips! I just ordered a Moto 360 myself and I plan on enabling Ambient Mode and disabling the tilt to display mode. If I plan on actually using my watch for a task I'm most likely going to tap on the screen anyway rather than tilting my wrist, and battery life will most likely be the same.
Soooo.
My watch just updated to the newest Android Wear version.
Now it seems my Ambient Mode leaves the screen on, regardless of angle!
It will be interesting to see how this effects my battery life!...!...!
I keep it all on.
I find both too useful to keep off.

I thought I was crazy but I just noticed this today. It turns out that ambient on and tilt to wake off leaves ambient always on. If you activate tilt to wake, the ambient screen turns off when facing out away from you or down. So tilt off, ambient on is what I'm going to try tomorrow to see how battery life is. The only thing I miss is the OK Google command just by raising my wrist.

I installed LineageOS 17.1 on my Moto G6 "ali". Its working fantastically except there seems to be no way to turn off the 'idle' screen that shows the Time/Date, and the battery percentage at the bottom.
Lock Screen is set to none, Screen Saver is set to none, Moto -> Ambient Display is set to off. I've turn off everything I can find, but the screen is still there. I believe it is killing my battery because an LCD screen cannot turn on just a few pixels the way an OLED screen can and I think thats what this page was made for. Anyone know whats going on and how to turn it off?
Strange. What GApps have you installed? Can you try without for evaluation?
After a lot of trial and error and asking around, the problem has been found. Display -> Lock Screen -> Always show Time is the setting, but Display -> Lock Screen is not available when the Lock Screen is set to None in Security. I added a PIN lock, got to the menu to turn off Always show Time, then removed the PIN lock, and its fixed now!
