Iv always considered battery life a very important factor in my purchasing of a phone and was one of the big reasons i moved from my Desire HD to the Nexus S (amongst many others). However having been on the android scene for a while im used to tinkering with kernels and roms etc and due to the new battery graph in gingerbread im now able to make direct comparisons rom by rom and kernel by kernel to see how they all differ. This is all shown + explained below.
First id like to explain my method;
I install the rom and kernel with the same apps I always use and charge the phone fully until i am about to go to sleep. I then unplug the phone and leave it in the exactly the same place on my desk with exactly the same settings (sync intervals etc) and i kill all apps before i leave it just to make sure the test is fair.
In the morning i then take a screen shot of the battery life over the period of usually 8 hours and will upload this for you to see. I then look at the over-night battery drain as a comparison on how good battery life is on specific roms and kernels.
Justification - Many of you may be thinking who cares about standby battery life? I care about the battery when im using it!?
Well although that's valid there are many reasons i have taken this approach;
1. It is completely fair i.e. no individual differences such as 'im a heavy user' but we all have different definitions of a 'heavy user'. This is eliminated by the fact the phone is not used and thus the same every time (no individual differences)
2. If a phone has severe battery drain during sleep general knowledge should dictate that battery drain should increase when the screen is on, cpu is working and your syncing your facebook wall, thus a direct correlation with sleep battery drain and usage drain should be apparent.
Therefore i have decided over the next few days/weeks etc i will upload on a regular basis a screenshot of the battery drain over night, along with the battery use details and screen on time etc etc. In addition to the rom and kernel info and i hope that over time this proves to be a very useful thread.
I have been doing this over the last few days on a less strict system and there have been some VERY interesting results which i will upload over the next few days.
(Just a final note iv never really done anything like this on xda before so if its a stupid idea then please tell me now so i dont waste my time doing it, however if people are really interested please let me know and il make sure i do my best!!)
Thanks for reading my extremely long post!

SCREENSHOT 1: This was using modacos custom rom r10 and the kernel that comes with it, i had quite a short sleep (about 6 hours) but the curve pretty much shows what the point im trying to make is. The battery life is great!!
SCREENSHOT 2: This is CM7 Nightly build 27# with Netarchy's latest 1.2.1 kernel and although i didnt use the screen once of charge for a few minutes as you can see once the screen was off battery life barely decreased and was over a long period of time.
If anyone wants me to test specific combos please let me know.
I'm actually looking forward to reading your results.

I'd be interested in seeing CM7, just whatever nightly build you manage to catch.
I don't think that result will give you precise result.
I found that statistic is wrong sometimes.
It is better to measure using "play video loop".
So, find a movie, set to the same brightness and play in loop?

Unfortunately that will not give you how well the rom does while it is idle.
I'm really looking forward to your results. My only issue with this phone is the battery life is terrible. I ordered an extended battery off Ebay 3 weeks ago and have yet to receive it. Never ordering anything from Hong Kong again!

What were you using before that you consider this phone to have bad battery life? By far this phone has the best battery life of any Android device I've owned. If you want bad battery life, get an Evo. That is horrific battery life.

I am looking forward to the rest of these, however just a quick question. What was your battery use like in that situation with the stock ROM? Just for reference, because I'm thinking I might switch to modaco soon. Thanks!
More soon
Iv got a few more screenies but it seems i may have to end this thread prematurely. Its the SNS or 2.3 but idle battery usage for me is pretty much identical no matter what the kernel or rom (il upload a CM7 + Netarchy 1.2.1 shot top op). This was unexpected on my behalf because with my DHD kernels and roms had a big impact on idle battery consumption. I have noticed however that without a full wipe when changing some kernels such as with M r10 idle battery life can increase drastically. I will continue for the next few days and if i dont see any big changes i may move method to a video loop or something of the sort.
Interesting find
I found out something today that may interest may of you. I was messing around with the sleep profiles on SetCpu with netarchys kernel and i found that its better to leave the range from 100-800 than 100-400 or less. This i believe is because when the phone is asleep and carries out a process it will be forced to clock to the maximum of 400mhz and then stay at that speed for 10 seconds, instead of say going up to 800mhz for 1-2 seconds to complete the same process. So a tip to you would be set your profile to 100-800mhz conservative and see what you get!

This kinda enforces the point that SetCPU is useless for the NS unless you really want to overclock...
Any battery saving tactics used buy lowering screen off profiles are counteracted by the system process;( So i think in the context of battery life you are probably better to not use SetCPU

I would definitely move to a video loop or some other 'heavy use' task because when you think about it, not too much can really be changed when almost no power is being used in the first place.
You could also just mention your general feeling for the battery life of each rom, because quite often that is what I go by as my usage varies depending on a range of things (school day or weekend etc) .

Could you please test modaco r10 with Netarchy's latest 1.2.1 kernel ?
I would love to see the difference between modaco's default kernel vs netarchy's kernel.
On CM nightly 13, I just went 11 hours and I'm at 90%. That's 1/2% an hour. Not bad. That is with stock kernel.

Hey folks,
I am giving two kernels out to test. Don't worry, both are quite stable. However, I am looking at some different settings to see which gives better battery life. So, in an effort to avoid any "placebo effect" results, I am not saying which settings these are just yet.
What I am looking for, if you folks could be so kind as to check:
Battery life between the two.
Performance between the two.
Neither of these kernels are overclocked.
Please test using the same governor between both, preferably Ondemand.
Thanks!!!

I would love to help test, but I'd like to know if you have any good criteria for the testing. It's really hard to test something without any guidelines as maybe you end up using the phone more on one, or downloading or whatever, and both seem like 'moderate usage', but in reality they are quite different.
As a matter of fact, I'm having a hard time verifying the current draw on my phone, and knowing what is good or not good, in general.
Just use your phone as you normally would, for both.

How can you really tell how much better the battery life is in such a short amount of time to test?
This reminds me of a test that kmobs did back in the day for kernels on the nexus. Turned out that heavily undervolting the kernel has a negative impact on battery life. Where's jlevy at. I know he remembers.

Lol, that was quick. I'm thinking he wants testing to go a little more than 30 minutes with each.
I'll test out A for 12 hours and B for 12 hours, if you think that's suffiecent. That should get me through a full charge on each.
Should be sufficient.

That's correct. Stock voltage for the Nexus One was 975mV. Kmobs found that undervolting below 950mV had negative impacts on battery life.

i don't care about gpu or overclocking my device.. all i want is to unplugged the n4 form charger and go working in the morning and at night before bad to put it back in the charger - without it dieing on my before..
i had htc sensation and it last all day for me, i'm now 2 days with the nexus 4 , and after 12 hours the battery is dead.
i'm currently using Cyanogenmod 10.1 18/2/13 nightly . turn off locations, and Facebook sync. using only automatic brightness (witch my the way is very low), WiFi and gps and Bluetooth always off . 3g on.
thank you!
Usage varies across any ROM/kernel combo. No one can really say what's best, because everyone's usage varies. But, I can and will say, I'm having best battery life so far using asylum nightlies with matr1x 7.0 kernel. I have a very strict setup which I'm not getting into, but I am in no way limiting the function of this powerhouse. If that makes any sense. Currently sitting at 63% with almost 3 hours screen time. 50/50 3g/wifi and heavy use. think streaming, gaming, downloads. It would take me a very long time to describe what I do to get this battery life, but I would be willing to explain if needed.

I'm using paranoidandriod with Franco kernel. I get great battery life all the time every time. Download the kernel and leave the settings as is and let it do it's thing.
Note: This has been asked too many times. You can search up the old ones and you'll pretty much get the same answers that it all depends on what you do. Battery life is subjective. It depends on the user. If someone only uses their phone for calls and text they will get awesome battery life. If another person has the same setup as the first they did play lots of game and play videos and such, battery life would not be so great. Thus, both users will tell you different answers.
Just try them out and see for yourself.

I didn't believed that sense based roms were superior than each other on battery or performance basis since htc one x days. But sentinel rom actually gave me a significant boost on battery life on all of my devices. (Nexus 7, HTC One, Nexus 4)
So I'm going to agree with you on this.

Ya. Not sure how exactly they tweak it to get better battery life but I'm happy... The cool thing too is the maker of the Rom takes suggestions from people and implaments them into the roms if he can.

I believe that it's not really dependent solely on the ROM but there are a lot of factors like usage, brightness and other things that either give you a good or a bad battery life. I have used the stock ROM, Android Revolution HD, and Trickdroid, and I got about the same battery life from both ARHD and Trickdroid (I didn't really keep the stock ROM except for a day or two so I wouldn't know). It's sort of hard to track the usage exactly in order to compare between two ROMs, because I for one use my phone differently every day, depending on how much browsing I do, how many phone calls I get or make, how many dropped signals, the brightness level depending on the lighting condition, and such. I must say, though, that I am extremely happy with the battery life I get from Trickdroid but I cannot say that it gives me a better battery life than ARHD, for instance, because that would merely an unimportant opinion that is not based on facts.

I tried to run a full day similar to that of those with trickdroid, ARHD and RGUI. And I just feel like the battery lasted a little longer on this Rom. I'm not sure if these developers can tweak software to change how long the battery last or not? But it does seem like there is a deference. I guess I should run it for a week or so on each Rom to get a true test. All I know is I love this phone and a longer lasting battery makes me happy as I can use the phone longer
On a side note. I am getting pretty slow speeds on speedtest with LTE. I'm getting 2 to 3 bars? Anyone know what that's about?? I'm only getting like 1.5mbps down and same up??

There is really nothing one size fits all kind of thing. Try these different ROMs for yourself to see what works best for you. It's hard to see which has better battery life since different users will have different usage stats.
I have to agree... One person might get great battery on RR and terrible on AICP, the next person the opposite. The only to really tell which one gets the best battery in your situation is to try them.
Data is too scattered to determine which ROM provides the best battery life. You see people getting all day battery life with different kernels, tweaks, usage, etc

I'm not trying to bash your post but TBH, any comparison you make from others is practically useless. As mentioned, people have different experiences on custom ROMs. One specific ROM might have excellent battery life on one phone and have horrible battery life on another of the same model. But there is an even more important factor that makes comparing across ROMs just as useless... Everyone uses their phone differently. Not just with apps they install, but with the features of a ROM they they decide to enable or not.
On that note, if you are considering a custom ROM, the best way to determine if it is right for you is simply to try them. Make backups that way you can revert back to the one you decide is best.
I know that every user use their phone differently. I don't know what made you guys think i don't know that. But what i am trying to compare is not overall battery life but battery life based on individual usage. Like when some one use that rom for only calls and get a lot of stand by time how much battery it drains. from that i can know how much battery it drains when kept idle. Same goes for using wifi or using mobile data , watching YouTube or reading PDF. I want to know how much battery that rom uses on what usage.

Referencing individual usage as you have, along with any specific ROM across devices, you are not going to get consistent results. I understand you are trying to consolidate this data on one post, but there are to many variables involved.
To highlight: I could run AICP on my XT1575 with a clean install and no extra apps installed and make only calls and I might get excellent battery life on standby. But another XT1575 owner can do the exact same setup, make the same number and times of calls and get horrible battery life. This pretty much goes for any custom ROM, especially those not based on stock. This does not even account for differences in MM vs N. This also does not account for an update to a ROM screwing up battery life and the next one may fix it (which is relatively common). I've even seen where someone gets great battery life up to a certain update and thereafter it sucks, but another can experience the opposite.
And once again, individual usage still matters as individuals will have different apps installed, which can take up varying amounts of battery depending on background processes and syncing. This affects standby time and SOT to some degree. Also do not forget that the chipset on this phone is prone to negative affects on battery depending on cell signal strength, so that is another kink in observing and comparing battery life across users.
Ultimately, the best way to determine what gives you the best battery life is too rest ROMs for yourself and your specific usages.

Yes ok. So we should be on the same page about different users using their devices differently. So if user A posts about say ROM B, and user B posts about ROM A, you know you can't compare. I would post my stats with RR but you couldn't compare to someone posting AICP stats as we are different users. The only way to be even somewhat accurate would be to get the same user to try different ROMs. Which you can do. Honestly just try the different ROMs! I will say with my experience though DU has not had the greatest battery life.

We understand what you are asking and we are telling you that there is only one way for you to get the information you are looking for. The only way for you to figure out what will have the best battery life in YOUR situation (how a ROM operates on YOUR specific device, YOUR selection of apps, and YOUR specific usage scenarios) is to test the ROMs for yourself.
Maybe there should be an app saving battery stats for the current ROM (internal storage or personal cloud), and comparing these personal stats with previous stats made when you had another ROM installed.
Of course there are other variables that affect the battery stats (like the apps installed, or the apps you actually open in a battery cycle) but at least the app would be able to list and compare battery stats on the same device and user.
Ie, I imagine a list like:
- ROM R1. Kernel K1. X1 apps installed. Battery rate: BR1
- ROM R1. Kernel K2. X1 apps installed. Battery rate: BR2
- ROM R2. Kernel K1. X1 apps installed. Battery rate: BR3
...
It could be able to group by Android version,...
I haven't found an app doing this. Do you know an app doing it? And, do you think this app would make any sense?
