It's not any one of them. It's any of them, potentially. Theoretically, the render setting you choose only works in shades of the chosen color, therefor doesn't have to process different colors/brightnesses as in normal mode. That's your "potential" power savings. It can also just look cool.

Really? That is very interesting. So even the last three options called calibrated which barely look different to me have "potential" battery savings?

If you have an amoled screen, then using night mode should help your battery life (in theory at least).
The calibrated ones look pretty different than how it does stock on my AMOLED Inc. Top one gives things a bit of a salmon tinge, the next one down makes things look slightly more blue, but barely. The bottom one makes things have a slight pink look to them. Normal just looks... Normal lol.

On my slcd they change drasticly. I use n1 low red to fool people into thinking its AMOLED.
Youre looking at a crackflashing troll with ORD

Can a dev please make a patch implementing this app/script/hack. The Inc has a red theme so I may be willing to go with a red display if it truly doubles battery time. I read something about adding an option to the developer app. Being able to turn it on and off would be ideal.
Thank you all in advance,

I would also be interested in something like this, if it can give me longer battery life.
Ehh if youre really desperate for battery life why not just do the recalibration trick? I'd rather have the battery run out quicker then have the phone look like that anyway.
The thing i don't get about this is they claim it can give your phone double your battery. Wouldn't the only thing this effect is the draw from the screen? I mean we already went from the lcd screens to the amoled screens and they are supposed to use alot less power and i haven't noticed any difference. My screen is only like 5% of my battery draw also....

this is correct. it won't make our batteries last twice as long, but it may reduce the power used by the display by about half. our display is not a battery hog to begin with. AMOLED is more power efficient than lcd 3/4's of the time. the only time AMOLED draws more power is on an all white or mostly white screen. this is why the web browser appears to kill the battery so fast.

I think that's a reporting bug with the stock Incredible ROM, because screen shots from a Nexus One show the screen being far and away the largest power draw. Flashing my Incredible to CyanogenMod also showed the screen as a large power draw (75% or higher). I didn't notice any appreciable difference in battery life either.

I'd rather not use my phone at all if I had to use it with that red tint. I understand someone using this to test but why would you want to use this all the time? If you need more battery, go buy a new one. Turning this on defeats the whole purpose of having such a nice phone and screen. It's like buying a V8 and disabling 4 cylinders to save gas.

I can see how it would be useful to toggle on in certain situations (emergencies, etc). The amber tint didn't seem quite as hard to look at as the red did.

Yeah, I'm quite sure that number/percentage is a weighted average. That's why "cell standby" appears so high, I think each one of those categories could be duty cycle or total percentage of potential power drain, such as 65ma/120ma= 55%, although it's obvious that the display will be one of the major drains -- it's always "on" unless the screen is fully asleep or the phone is off--let's not forget the backlight, which is totally independent of pixel intensity/color's specific power draw.
I'd like this as well, if only because the lowest brightness is pretty bright to my eyes in complete darkness!
I am really interested in seeing this on the incredible.
I am an amateur astronomer, and the night vision mode would be really nice to have.
We may have AMOLED screens but soon there will be a ton a people with LCD screens... remember the switch because of the screen shortage?
Granted I probably wouldn't use it much... it'd be more of a novelty for me.

There are official Samsung ones for both CDMA and GSM variants. Both are 200mAh (~14%) larger than their respective stock batteries.
I ordered a 2000mAh battery from MugenPower or something similar (Hongkong based I think). It´s the same physical size as the stock one. So it doens´t add any size at all.
I was having trouble getting used to the ****ty battery as well (coming from the old "brick-style phones"). But having rooted, tweaked, switched around and most of all learned how things work. I´ve more then doubled my battery time. So yeah, I´d recommend getting into it.
Does take some time reading up on things, but when you start getting the hang of things you can reap the rewards.
Beware though, you can easily turn into a flash-crack-head

You might want to check that it's actually 2000mah. One would think if Samsung could fit 2000mah into the same size battery they would.

root your phone and flash a custom rom if you dont like stock and I like franco's kernel for awesome performance and battery
Franco was nice but I still got better battery life from Lean kernel.

Oh and so you know what really kills the battery on the Nexus is browsing. Supposedly the white background on the majority of websites takes more power to render than a dark screen.

It's not that white takes more power to "render", its that AMOLED screens use the most power to produce the color white. When AMOLED screens create dark (or black) colors, they can actually turn the invidual LED's off, using less power. There's no backlight on an AMOLED screen that needs to be lit 100% of the time.
But really, a 720P AMOLED screen will take a lot of power up whenever it's on, whether you're gaming, browsing, or doing email. The screen is just a big power draw.
That is all, i am using it from market and works great by decreasing ThE brighht level as much as you want.

It doesn't actually decrease the brightness. It only applies a great filter over it so things appear less bright. It doesn't actually save battery on LCD IPS displays. Only on amoled displays.

Stop... MUFFIN TIME!!!
Yeah it just puts a filter over and makes everything darker. Brightness level is the same
Yeah the only way to save energy is to dim the backlight which isn't what this app does.

I always set my apps to black/dark theme if available.
But maybe this doesnt have any impact on battery life at all and black LEDs still need power?

You do it right, go on setting dark theme because it really helps (i don't know how much but helps) saving battery since in oled screen the led are completely off top get the black colour AFAIK.
Nexus s user/dev bedalus had An epic battery life thread that I'm sure you could find if you googled it (on my phone otherwise I'd post the link). White uses the most battery. Black the least. The most interesting results showed that red used less power than the other colors, so a black/red theme would be best for battery.

Hello,
I've been using this device for about 5 months now and the battery life for me has been great so far, but there's so much you can do when you need the juice in your battery last longer. In order to help those who want to get the best battery life out of their phone, I've compiled a list of things I do to make my phone last longer.
We'll go from the things most effective to the least and mind you, all of these can be done without rooting of using ADB etc. So let's start
'''Turn on Gray Scale'''
As we have an AMOLED screen, turning on grey scale will give you an improvement in battery life of around 25-35 %, and it's especially noticable if you use your phone in high brightness mode.
'''Dark theme'''
Dark theme obviously saves battery on our phone, there's and awesome guide on XDA guiding you to do it without rooting or using any theme engine.
'''Set brightness to 50%'''
Our eyes don't perceive brightness linearly, so 100% brightness will take around 50-70% percent more battery than 50%, but going much lower won't help either cause increasing brightness from 0-50% results in around 20-30% extra power draw.
'''Restrict background running of less used apps'''
You can restrict an app from running in the background and this setting is baked right into the App Info settings,
Go to app info and tap on battery usage, from there, restrict the app.
'''Enable data saver'''
This can be enabled via Quick Settings menu and this can drastically save battery if you're mostly on Mobile data.
'''Turn off Auto Sync'''
It is long known that doing this can save a bit of battery.
'''Enable Battery Saver'''
Pretty self explanatory.
'''Change minimum width'''
Set minimum width to anything less than 400, this leads to less information being displayed on screen which results in lower usage of GPU, and thus better battery (somewhat)
'''Reduce animation duration scale'''
This will speed up everything and improve battery life just a bit.
And that's it from me, if I remember anything else, I'll make sure to add it, and please make sure to tell me anything that works for you, I'll happily add it.
If you want to get absolutely the best battery life out of your device, you must install a custom kernel. I'm using Fenix currently.
Also, turn off printing service. This idiotic thing is turned on by default. It keeps sucking battery for no reason at all. I'm not using stock ROM now but you can find it by going to: Settings>Bluetooth & Devices (or something similar)
Can you post the link of the thread for enabling dark mode I would like to try that.
Another tip - switch to airplane mode, mobile network is one of the biggest battery consumer..
But seriously, how does greyscale mode save the battery? Instead of glowing one of the subpixels for displaying a color, all of them must be shining to provide different shades of white color. It might even use more power.
Width change and animation duration scale have some very interesting thinking behind them, it will have absolutely no impact on the battery.
Dudes, just enjoy and use the phone. Why do you want to cripple your experience just to gain extra few percents of battery per day? If you're living of the grid, there are much better phones for such a lifestyle.

There's an XDA article comparing battery saving with AMOLED on black and grey theme, you might want to check it out, or you can also watch a video by Mrwhosetheboss to see how it went for him. As for animation speed and DPI, they have the least effect on battery life as I've stated above. Kindly do some research before you start making claims.

Where exactly in the article does it say that monochrome display saves power over colored one? Actually it's you who started with unique claims, so please provide some proof.
