When you go into battery info there is info about your signal strength. What do the different colours mean? I presume green is the best and good, what do all the other colours mean? My battery is best when green. when in low 2g signal area, dark yellow(?) It seems to use more battery as its struggling to hold onto signal?

Green basically means you have a good signal. There are some shades of green, shades of yellow, and then gray, then red. Red means your not connected to your carrier, and you probably are limited to emergency calls (911).
The better your reception, the less power your phone uses. If it can't get a good signal, it increases power and searches for better connections.
Thought that was the case, thanks!

use it for yourself and find out. radio results won't be the same for everybody.
To my understanding the radio stays the same? the only change is to the listing of towers? and the change of the way it toggles from 3-4g service.
I could be completely wrong though...
4.0.4 seem to use more power when in low signal areas than 4.0.2 and 4.0.3, at least during active use. FA2 will cut battery life in half (1.5 hours of on-screen time vs ~3 hours in good signal areas). Older radios/OS combos generally gave me ~2 hours on screen time in signal poor areas.
4.0.4 seems to have slightly better signal than 4.0.2 and roughly equal to 4.0.3 in my area. I don't think it's commensurate/ proportionate with the slight increase in signal. For a 25% decrease in life, I'd expect a more solid signal and less jumping around between towers.
I get AMAZING battery life when I'm on wifi but terrible battery when I'm not. I send/receive about 300 texts a day easily and so I have the screen on frequently. I also use web a lot. On wifi my battery will last about 20-24 hours probably. Currently I'm at 67% on 6 hours. Without wifi, I will get about 8-10 hours with the same kind of usage.
I just want to know why there is such a large discrepancy. Im in NYC so my signal is pretty strong.
I used to think it was the screen that used up so much of my battery life but now I'm thinking it's the radio.
I'm on Juggernaut. If anyone has a suggestion I'm all for it. Should I try a different kernel? If so, which one?

Jugs with dark x kernel works very well with me i use faux clock to clock it at 1.7 and 384 gettin 16-17 hours of battery life with lots if texting and browsing hope it works

So when you use your phone, do you not expect the battery life to go down? It can't stay at 100% after everything your doing..
I recommend Juice Defender. It turns off data when your screen is off. Sounds like you're getting a lot of screen off drain.

I do expect it to go down. Hence I thought it was normal until I noticed a huge difference in battery between being on 4g v. wifi and getting double the battery life while doing the same things.
I'm just wondering why the 4g takes that much more than my wifi and if a kernel would be an issue

The simplest explanation that I can come up with is twofold.
First 4G requires a MIMO type of connection, even on T-Mobile. So for the really high speed connection it actually uses more than 1 antenna and powering more than one antenna takes up more power.
The second part is that 4G connections are not as prevalent as 3G connections so your phone has to search for the closest 4G network more often to maintain the fastest connection and the network searching takes up even more data then than the MIMO style connection the phone uses for 4G.
The combination of these two will drain your battery much faster than a single antenna connection to your home wi-fi that does not have to pass as many syn/ack packets to maintain the connection as the 4G network and thus uses less energy.
(MIMO stands for multiple in, multiple out which means it uses more than one antenna for incoming and outgoing transmissions)
(Wirless-N is MIMO based as well but does need to use as many "discovery or syn/ack packets" to maintain the connection)
I second juice defender. You can configure it to turn off data while the screen is off which will not effect your ability to receive phone calls or text messages.

looking at my screen....the first 50% of the battery drained "fine", i guess but look at the next 50% or so....especially that weird red bar in the battery graph......
what's going on? i eliminated the crappy wakelocks and still this crap happens.
im on CM10 btw
I don't see what the problem is. You have over a day of battery on one charge (I never get that). If you're referring to the red bar in the mobile networks part that means you had no reception. When you have no reception the phone is constantly searching for a signal and will drain your battery quickly

Well the over a day thing is pretty normal for me. I use juice defender and setcpu so it works everything out.
I have some questions regarding the battery graph
When i touch on the battery graph it wil show history details with mobile network signal,gps on,wi-fi and so on.
Mobile network signal shows mostly in green with some red in between where as the rest are all blue.What does these colours indicate?
I flashed XXLH1 radio and only then ive seen this green.Before it used to be blue.
The mobile bar indicates the signal strength, and the other shows how much those features have been used.

so is the green colour good?
Green = full bars, 3 bars = blue, red = 2 bars i guess.
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.
