Is there a dark themed ROM that is battery oriented? I know you could use substratum, but most themes I want cost money, and for the battery, I'd like to stay away from root

I have read that a black or dark theme could save a bit of battery with oled or super amoled but not with non-oled screens. This is apparently due to the way the backlight works in lcd screens.

on G2x is it better to had dark or light theme to minimize power usage?
I think G2x has LED witch would mean darker would be better and on LCD white.
Does G2x has LED?
that rule only applies to phones with amoled screens. the g2x has a backlit lcd screen so dark vs light themes wont change power consumption. screen brightness is what you want to worry about.
Thanx

With pretty much all the current themes being black, dark or various shades of red, I was wondering if there are any good "light" themes out there for stock. I'm running Bones Stock and am using (and loving) the Note 2 keyboard, so it would be nice to have a light theme for that too
Hi everyone,
It's my first time using a Nexus device.
I just switched from Samsung Galaxy S2.
With the samsung screen, the black is a real black whereas in the Nexus the black shows the backlight of the LCD (or however it is called now) screen so there's this white glow coming out when it supposed to be pure black screen.
I'm not referring to when the phone is off, I'm referring to when it suppose to display pure black background like when using the Daydream clock feature.
I'm not complaining, I'm just trying to understand if this is how it supposed to be
Thanks

It's normal. Use this for awhile and then go back to the s2, I have one too. You'll see how much better this screen is.
I agree that sharpness and colours are amazing on the Nexus but it's not the black colour / contrast I got used to from the S2.
I came from an S3 and I love the screen quality. I can actually see my phone in daylight.

samsung uses samoled screens, the blacks are blacker and the colors are more vivid. but, samoled screens dont show the real colors, they are much more overly saturated. oh, and black.. samoled dont light up pixels for black, thats why it seems blacker.

I could see as well with the S2
Anyway, as I was saying, I'm not complaining or anything... I just didn't know if the black I was expecting to see on the Nexus is about the same as in the S2...
Unfortunately, I must admit that the S2 presented a much deeper black and the Nexus 5 displays white glow rather than black.
IPS != AMOLED
S2 -> AMOLED. That's almost pure blacks and too saturated colours.
N5 -> IPS. In the N5's case, pretty accurate colours, but with background light, cause the tecnology is like that. You're not gonna get black blacks with IPS. The panel is quite a lot better in every other aspect though.
thanks @Molitro
I agree that besides the blacks, this screen is amazing
As others have hinted, only Oled screens can turn their pixels off complely (0nits) and that's why they can do cool things such as active notifications on the Moto X. When looked on head on the black levels of the Nexus 5 IPS screen are quite good compared to other non Oleds. Infact it out right destroys my desktop and laptop Tn displays in that regards.

In the smartphone market the majority of displays are either AMOLED or LCD, but many people don't know that the wallpaper color you choose, yes, wallpaper, can actually make a difference to your smartphone battery life depending on the type of screen with which your device is equipped. Pure black wallpaper, or a dark-colored background in general, can actually save you a significant amount of battery life.
Display tech explained: LCD
LCD stands for Liquid Crystal Display and it's the same kind of technology you'll find in your televisions, monitors and so on. As the name suggests, Liquid Crystal Displays are actually crystals, and as such, they don't emit light of their own but rather transmit light from a light source behind them.
This means that even if you're looking at black on your smartphone or tablet screen, it is actually black lit up from behind. Therefore, LCDs don't really display "true" black
Display tech explained: AMOLED and OLED
Next, AMOLED. AMOLED stands for Active-Matrix Organic Light-Emitting Diode and it is also used for televisions screens but more notably, for smartphones. OLED displays are similar, but do not use an Active Matrix.
Samsung displays, for example, are usually AMOLED: the Galaxy S5, Galaxy Note 3 and Galaxy Note 4 all use an AMOLED display. The LG G Flex 2 uses a Plastic OLED display and the Google Nexus 6 also uses an AMOLED screen.
As the name implies, the screen is made up of organic material that actually produces light when a current is passed through it – electroluminescence. Because AMOLED displays can be lit up pixel by pixel like on the Moto X, black is "true" black because there is no back-lighting.
This also means AMOLED displays are easier on your battery because every pixel is not always lit up.
Battery life: AMOLED vs LCD
AMOLED
You can probably see where this is going: if you have an AMOLED display then you can actually save some battery life by using black wallpapers, or generally darker wallpapers and themes.
little experiment and figured out that you can save about 6% battery life/hour at 20% brightness by using a black wallpaper on an AMOLED display, and about 8%/hour at full brightness.
These results are based on an always-on screen, but the basic theory is sound even if the figures are not exactly set in stone. Another tester using a different method came up with a general 18% saving all day.
LCD
What about LCD battery saving wallpaper, I hear you ask? Sorry, LCDs rely on back-lighting, so there's nothing you can do to save battery there.
The only thing you can do is set your device settings to Battery Saver mode and try not to turn your screen on all the time. Keep your display brightness as low as possible and your screen timeout nice and short.
The good news is you can have the brightest colored wallpaper and themes imaginable and it won't make a difference to your battery. Just think about that when you look at the gloomy screens of AMOLED owners clinging to extended battery life (just don't stray too far from a charger while you gloat).
Other battery life tips for AMOLED screens
There are other things AMOLED owners can do to maximize their battery life too, like setting as many app themes to be as dark as possible.
If you can change the appearance of a bunch of apps you use frequently (or download a different app that does the same thing but that does allow appearance customization), you can save even more battery life.
After all, we don't spend all day on our home screens but more time in apps. You can also set your text and email preferences to be black background and white text, depending on your device and chosen apps.
The easiest way to figure it out for yourself is to fully charge your device as is and wait until it's almost totally dead and look at how much of your battery was used by the display. Just go into your Settings menu and look under Device Settings for Battery.
Make a note of the percentage your display has used up, then, while recharging your phone, switch to a black wallpaper and repeat the cycle to see the difference.
Great app :good:
Hi everyone , one of the first tips to extend your battery life and customize your device is downloading a theme (dark for more battery life ) I've downloaded a few ones with are supposed to be dark but they're only a dark grey theme, I haven't seen a true back theme that takes advantage of the amoled display , so if there's any theme developer seeing this the xda community would love to download a beautifull amoled theme for the amazing display of the s7 edge
Try this. It's awesome.

if you like material design, try to search Material Black. This is different from Material Dark.
You could try Blue and Black Amoled. Black backgrounds, white text and a few blue accents.
