monochrome display

[Sonic Design]

Want a monochrome display on your phone? Think kindle paper back display, its kind of cool and saves some battery life, and here's how to do it.....

Step 1: go to "settings"
Step 2: go to "about phone"
Step 3: go to your "build number" and tap it about 7 time it will say "you are now a developer"
Step 4: go to "developer options"
Step 5: go to "simulate color space"
Step 6: select "monochromacy"

And bam you're done, your phone will now display in black and white only, to undo this just go back and follow step 4&5 and then select "disabled" have fun

Glad to see I'm not the only one who loves greyscale. It's odd in a lot of areas but fun none the less.

Yea I think its really cool, and a good thing to set it on while at work or out for the day and not really on the phone so much, but have a phone that gets poor battery life, it helps.

awesome! there are also other color modes

 

[Sonic Design]

Yea there are 4 options for other color modes

I wonder how much battery it actually saves

I would rather enjoy the full potential of this great phone. pedal to the metal and no slowing down is how I like it ?

well i dont know if its possible but if you can combine it with buildin battery saver option via a tasker or iftt shortcut maybe you can simulate touhwiz battery saver feature,which mean if you have amoled display in your phone this could really help

i have been trying to do this.but i need to know how to get simulate screen colour>monochrome activity name and make a shortcut for it

does this make nexus 6 a little laggy for any one else? and i read somewhere that it stresses out cpu as it is doing extra work to simulate monochrome.

also can anyone confirm if it makes battery last longer. because when i last used it it was all laggy and i was getting battery drained faster than the usual 5-6 hours SOT i get without any issues.

why would monochrome save battery? all pixals are still being used, and differing shades of gray do nothing. sure, pure black helps, but grays do not(grays are most common in monochrome).

Next step - buy a Ferrari and drive it around in first gear only...
Duh...

Troll? Why do you say that? It's a perfectly reasonable comment in reply to someone who buys a very expensive device with a superlative display and then neuters it for the sake of a few minutes extra battery time, and even that proposition is questionable.
Try again. Why am I a troll?

i agree with you, BUT the wording choice could come off as being rude. could as in many wont find it rude but some will.

 

[dahawthorne]

Point taken. Apologies...

First off, everybody already knows about this.

Second, hate to break it to you, but doing this will actually REDUCE your battery life.
Why? Well first off, there is processing overhead to convert the colors.
Second, WHITE is the color of maximum power consumption. It corresponds to ALL subpixels being turned ON.
Red+Blue+Green = WHITE. ALL subpixels are turned on and eating power.
NOred+NOBlue+NOGreen = BLACK.
Red + NOBLUE + NOGreen = RED. Only the RED subpixels are turned on, power consumption roughly 1/3 of white.
Understand?

Don't be so rude mate, not everyone has the same level of knowledge regarding Android, CM, Nexus 6 display panel ... you could have given the very same technical arguments but with no offense.
The spirit of the XDA community is hacking, trying new things, investigate in an open-minded way, explore our devices beyond OEM's trails... and newcomers don't always have the same technical background, so let's all chill out and remain open :good:

Being factual, accurate, and correct, is not rude.

If you disagree, then you obviously have some kind of problem where you need somebody to hold your hand and stroke your ego continuously to keep yourself out of the crazy corners of your own delusional mind, and if THAT is the case, then the only thing I can suggest to you, is that you stop being such a

There, see the difference? THAT was rude.
