It is about "AMOLED: Black wallpaper = Battery saved?"
As I promised, I have done a simple non-scientific experiment:
(1) At maximum brightness, screen on for 15 minutes
- Default wallpaper will consume about 5% (from 36% down to 31%)
- Pure black wallpaper will consume about 3% (from 30% down to 27%)
(2) At brightness = 20+%, screen on for 15 minutes
- HTC Black wallpaper will consume about 2% (from 26% down to 24%)
- Default wallpaper will consume about 3% (from 23% down to 20%)

All the above experiments was done in this condition:
- Wifi OFF
- Mobile network OFF
- GPS OFF
- Bluetooth OFF
- Screen at home screen with default HTC clock (white background with weather)
* The HTC Black wallpaper is available by default when you choose HTC wallpaper. It is not pure black, but it is still black
So, conclusion, using black background will save you battery life. The above experiments were conducted at 15 minutes each and you immediately see the difference.
I would say at low brightness, 20% - 25%, you will get 1% up to 2% battery saving per 15 minutes, let say 1.5% per 15 minutes. For 1 hour you will get about 6% battery saving.
Of course, of course, I know, who will stare at the home screen for 1 hour? But who knows? In the course of the whole daily use with the phone, how long do you think you scroll left and right in the home screen?
Or imagine you are browsing XDA forums a lot, every day. It would be better using the Android XDA app by Tapatalk because it uses black background instead of browsing via web which uses bright yellow background!
Also see how the brightness affect the battery life. My eyes is happy with about 20+% brightness
Again, this is non-scientific experiment, but it should give you rough idea how much your amoled screen uses battery power
PS: Yes, I have nothing to do this afternoon Too much time, He he he ...
i said so
thanx for conducting the experiment, this proves to people that say "black bg doesnt effect and is not worth it"
I just changed my default web browser home page, from:
http://www.google.com
To
http://www.blackle.com/
They will give you the same search result but really different background color.

Thanks for sharing but I don't have an Amoled screen to go and sit in the dark
I will charge earlier with bright vivid colors after 48 hours

thats just madness mate
Very very nice!! I am just using night mode on amoled screen using ebook reader with brightness off, i just say that energy save is uncredible.. Thank you!!
Red is better on the battery.
The Black Color Keeps And Saves the battery longer cause they turn the display and the LEDs completely OFF , that's a LED Display characteristic to turn off the leds of the area it want to show BLACK color & the main advantage ( ithink ) over an lcd , since u''ll have a "pure black" and saving power , but on a lcd even how much the LCD is of a high quality it's always ... grey ( since there is always a BACKLIGHT )
what a pointless experement get a job lol
at night what's the best option to turn airplane mode?

hold the top power button for a few secs.you will have the option to turn on of flight mode , data mode , power off etc..
i know but for alarm to be active and same time conserve battery flight mode?

Yes, that would be okay! Because even in Flight Mode, your alarm should go off!
You have an enery saver, although, when you wake up and you forget to turn your Plane mode off, than you can't receive or make phone calls, so thats why I dont use it!

or use an app called sweet dreams
Timeriffic is better IMO.
so sweet dreams or timeriffic for alarm and battery savings?
For the ultimate battery savings, turn your phone off.... If you have it on airplane mode it is nothing but a glorified mp3/alarm clock. Turn it off and the alarm will still activate in the morning (or whenever you set it to go off).

Really?? Are you sure?
I was under the impression that when this phone is off, your alarm will NOT re-awaken the phone.

More contrast status bar. Useful for bright sun conditions, especially when using device as navigator.
Fixed some battery percentage issues in no charge (overheat etc.) modes.
Optimized battery charge animation (34 pictures, instead of 100)
Suppressed subsequent NoCharge dialog windows. Only first one will be displayed. No Charge condition displayed in battery icon in status bar.

Main difference:
In stock ROM this message displayed every minute after temperature achieve 60C until it dropped below 40C or charger disconnected.
In this MOD it displayed only once for each event.
True "always-on" ambient mode available on Moto 360 with the new LCA44B update
Try this:
- Enable Ambient Mode on the watch
- Disable "Tilt to wake screen" setting in the Android Wear app
The screen will now stay on indefinitely, just like a regular watch. Until now, the Ambient Mode would always turn the screen off after a few seconds and there was no true "always-on" mode available.
PS: Battery drain seems to be the same as before.
Interesting battery life claim. did you get to verify it for more then 1 day?

Almost just like a regular watch.. Screen stays on but gets dimmed after a few seconds. At least: mine does.
So it stays on even with the watch down by your side? Pretty sure ambient mode kept the screen on before any time the watch was nearly level (like when looking at it).

I don't understand this. Of course the screen will be dimmed when always on, this is what happens for all smartwatches and even all the laptops by default when not actively in use. This is a sane thing to do. I wouldn't want my watch to glow in the dark when I'm walking.
Plus, are you able to tell the time when looking at your regular watch in the dark ? No. You have to press a light button (if present; if not, you are out of luck). With the Moto 360 you are able to see the information without pressing any button, even in the dark.
The purpose of the always-on mode is to have access to information with no delay at all times, and that's what it does.

I was referring to your comment "like a regular watch". A regular watch always has a clear display, has it?.
I monitored my battery usage. From 6Am till 2pm my usase was 33%, so about 4% per hour. After switching to ambient mode from 2pm till 7pm my usage was 54% so about 11% per hour. Now 9pm my watch is empty. Normally by this time my battery still is at 40%.
Could be coincidence (?)
But still thanks for your tip.

Of course it's not coincidence. Ambient mode drains battery faster, everyone knows this, the watch also tells you this when turning on the ambient mode. When I said the battery drain seems to be the same, I referred to the drain with the new "always-on" ambient mode versus the drain with the "old" ambient mode from before the update, when the screen still turned off after a few seconds but was more sensitive to movements than the regular mode.
i don't think i'll be using ambient mode with the moto360... so this new "feature" is useless to me (or those who need their watch to last a FULL DAY)

If you consider a full day a working day, it lasts a full day without any problem. Mine lasts 16 hours with Ambient Mode on and I get many email and chat notifications. It doesn't last 24 hours but anything between 16 and 36 is useless because the watch would die on you the next day in case you miss a night's charge.
With WatchMaker, you can control how the screen looks while dimmed, including keeping it on full brightness (maybe just removing the second hand so it doesn't have to refresh so much), but I agree this would not be a great option for the 360...
All Android Wear devices have always done with it seems this update does for the 360.

I'm considering using ambient mode but I'm not so sure. I'm using tilt to wake the device up. I heard battery life is similar to tilt to wake anyway when comparing tilt to wake and ambient mode together.

Has anyone confirmed ambient mode does noticeably have more of a battery impact?

After testing the Ambient ON + Tilt OFF (true always-on) mode for about 3-4 days with varius settings, I came to the conclusion that this mode drains battery significantly more than Ambient ON + Tilt ON,
Ambient ON + Tilt OFF lasts around 12 hours.
Ambient ON + Tilt ON lasts around 16 hours.
Ambient OFF + Tilt ON can last around 22-24 hours.
However, the always-on mode improves the functionality and experience so much that I wouldn't consider switching back, I prefer to just live with the shorter battery life.
I feel that there can be so many improvements that could be made regarding the screen, for energy saving purposes, but Google and Motorola just don't think of them. For example, notifications wake up the screen but there could be an option to disable this and only wake up the screen when tapping or pressing the button.

That's strange why do you think Ambient ON + Tilt ON gives out more battery life than with Tilt OFF?

It's normal, the Ambient ON + Tilt OFF keeps the screen on all the time, while Ambient ON + Tilt ON behaves like the old ambient mode, switching off the screen most of the time, just being more sensitive when you move your hand.
just so im using this right..
if i have ambient on and tilt OFF then the only way to WAKE the watch is to tap the screen?
the watch is dim and its great but to wake it, i have to tap the screen..
so is that how this setup works (ambient on tilt OFF)?

Hi!
About month ago I have bought an Asus Zenwatch and updated it to latest firmware. Last update that adds interactive watch faces also was installed several days ago.
Yesterday evening I have discovered weird issue that after some time in ambient mode the screen turns off. On tap it goes to normal mode and displays all colors and watch face correctly.
I have tried Reset settings option in Settings menu, enabling and disabling ambient mode from watch and Wear app, reinstalling Wear app and cleaning Play Services data, but it didn't help.
Could you, please, help me with this issue? Maybe this issue can be tracked using ADB?
Also in the Saturday morning I have a trip at town for a long time and the weather was hot. Temperature was about 30 Celsius degrees. Maybe this information can help.
Best regards, Mikle.
It is normal for the screen to go blank after a period of inactivity (about 30 mins), at least it is with mine.
I have the same issue
1) Can i disable the functions of "cardiac activity" "pedometer" ?!
2) Battery life is very bad, what can I do to optimize it?
3) On reminders and alarm clocks, it doesn't vibrate, why?
nothing?
up
I just got mine and the performance was horrible. I had to let the software update to 5.x from 4.x and after that was done I deleted it from my phone and then did a factory reset on the watch. After I did all that I used a moto watchface and had 36 hours.
On optimising battery life:
Turn off gestures (tilt to wake, etc), ambient mode (the display doesn't need to be on all the time, press the side button or tap the screen), and wifi. I also turn mine off every night when I go to sleep (I never wear a watch to bed, anyway) and I can usually get 3-4 days out of mine, with decent use of the actual smartwatch features (voice texting, media control, responding to notifications).

Although it rear tilt to wake option is disabled, the watch lights up when it turned up in the display.
Probably something else causing it to light up, but I'm not sure now what.
If there is a clock faces that have settings for this, those in the WatchMaker Premium application do not have this option to turn off tilt to wake up for reduce the battery consumation.

The Android Wear app is the only place that I know of where the tilt to wake option is located.
I don't use either Facer or Watchmaker Premium, so I'm not sure about that option under either app.
Using either app can cause extra battery drain, since the watch communicates with the phone constantly (or at least frequently) to update the watch face.

You're right. I probably had in mind the possibility of stopping this option from the watch itself, which does not happen until you stop the application Android Wear, as you mentioned.
Alternatively, it is talking about is removing dim off the clock.
Thanks for your guidance.
