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.

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 had similar results using the yeti rom. Display was always in the fifties or higher.

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.

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?
Sent from my ADR6300 using XDA App
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.

The lighter the Theme is in overall the higher will be the consumed amount of battery.

Themes don't have much of an impact on battery life like they used to in my experience,the way way you set your phone up does.
#Display setting
#Brightness
#Animations
#Background data
#Auto sync
#Screen time out
#Apps with permissions to prevent phone from sleeping
These are things that give your battery a workout.
In the old days ( last year) my HTC Hero would "struggle" to display graphically heavy themes due to the specs, which would decrease battery performance.
These days that's no longer an issue, it's more the wear out of your screen.
Blue burns out the pixels quicker than other colours, but it will take years of continued heavy use of blue before you could notice anything with the naked eye, by then you'll have 10GB octi core processor with a flexible transparent screen that also does the dishes.
If you are of the opinion themes do affect the battery life.....that's what chargers are for.
With all settings same from stock ROM theme in miui to RDs dark orange v2.1, the battery is alot worse off and similarly if i use any of the windows lookalike themes the battery drain is terrible! I can only blame theme as everything else is same...unless someone has a better explanation..

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.

I am sorry to say, but the power saving only works for AMOLED screens. Quote from the play store info: "It even saves battery life for AMOLED displays!"

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.

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.
