Place your vote's of which ROM has the best battery life for your phone.
Good thread! I'm very intrested to see wich ROM has the better battery life!
Isn't this a bit pointless as they are basically very similar roms.

As far as I know - DeFroST is based on OD. So nothing to compare or vote here.

Not entirely the same. And both on different kernels also.

I had very bad surprises with both roms.
But I think the real problem are some apps.
Camera360 for example kills your battery in 2 hours.
So I don't vote

Defrost is completely build from source with cyanogenmod packages and framework. Kernel is different also (no overvolt [email protected]). Look at my github: http://github.com/richardtrip/

Thank you Richard. So there will be different battery life between the 2 ROM's. People need to stop saying that DeFroST is a total rip from OpenDesire.

I agree.
There WAS a time when OD and DF is almost similar inside out but as of lately both ROMs are very much different.
But on the question of which had better battery life my vote goes to DF. OD seems to be unstable lately and has turned out to be more experimental then stable (e.g implementation of multitouch droid keyboard, switching to HTC keyboard and now infusing elements from Galaxy S). I had more better power drain on DF and CM6.
Cor, this all seems familiar.
Anyway, instead of polls which to be frank are worthless in this regard, has anyone actually done any measured testing between battery lives of different versions of different ROMs? That might actually be useful and interesting.

how can an app which only runs when you open it explicitly drain the battery in 2 hours (unless you sit there with the camera on for 2 hours)
I've very bad experience with OpenDesire battery... I can't say the same about DeFrost, wich has a good battery life

I was once with OpenDesire a few days ago and don't consider going back because one night i had 59% battery charge and woke up the next morning finding that it's dead.
Going back to DefroST and running my same old apps that i previously had on OD works just fine. With my phone with plenty of charge the next morning
i think this thread would be more useful if people would give their specific experiences with the roms they use the most, as i'm sure there are quite a number of people that haven't tried one or the other long enough to give substantial feedback. i think people should include:
which version of the rom(s) they tested/used
what kind of battery life they experienced and with what type of usage (i know it's subjective and everyone gets different results, but it's better than just voting for the rom you used and saying it's the best)
length of time that was allowed to test (there have been occasions where rebooting or going through a complete charging cycle have yielded better battery life. so it should be noted if people only allowed the rom they tested to be on their phone for maybe 20% or whatever, or a couple of hours)
and any other information people think might help/be useful to others
also what radio people are running would be very useful as well
This is a development forum.
I think that this type of thread are useless, since battery life is too "personal" to sort with a silly poll.
Battery life is meant to be professionally tested with some program, with the same device. One can have faulty battery, another one can have a non calibrated battery, another one a new battery.
My two cents.

I tried DeFrost just for a while to see Quadrant score. So I can't say something certain about it's battery life. But OpenDesire I'm using rigt now has great battery life. I mentioned that today in OD thread also. With normal use(Web, lots of messaging, GPS etc. 768 mhz cpu speed (it does 1300 Quadrant score with that speed) and 2G mobile network) I've used it for 70 hours. Really impressive I think.

If you don't leave the app with the back button, it runs further in the background-

For what reason?
soooo many different aspects to battery life that just asking randomly to 'vote' is indeed not helping too much.
I won't say it as blunt as 'please close this thread' but really helpful it's not.
For example, what if - eehhhhm, let's pick Defrost - DeFrost comes out as 75% voting to have better battery life. A new user comes in, sees DeFrost as better, and picks that one. His battery drains within an hour, and he is thinking "WTF?!? insert random roob rage stuff here WTF!?!?!"
This happens all the time. Battery usage users are _so_ different based on usage, network provider, location and apps used / installed that the ROM really doesn't have much influence.
Only if there is a real 'bug' it's noticeable, and the dev's are quickly on it then.
Can anyone tell me which ROM (STABLE) provides the best battery life on HTC EVO???
Thanks!
I have been through just about all on this site and Fresh's newest seems to work best for me. With moderate daily usage I can go without charging for about 22-24 hours. Of course all I need to go is 12-14 b/c I charge every night anyway, but I did leave off charger one day just to see how far I could go. I'm giving Calk's latest a try right now to see how it goes. Just be sure to give whatever ROM you try a couple charges before making a final decision, as it usually takes this amount to get an accurate read on true battery life.
how many of these post are we going to need lol

I know that the latest kernels off the latest build have been killing my battery, it's horrible for my EVO.
But you really have to try different rom/kernel/PRI/radio combinations to find the best battery life for your Evo. I wish there was a preset rating system for each rom though, just to see how things work for everyone else(i.e. battery life, quadrant scores, force close problems, etc.)...but there really are a lot of variables, so I don't think that may ever happen.
Yeah I agree there isn't a clear cut winner. Everyone uses their phone different so it will differ for everyone.
Totally agree to give it a few full charges... I suggest when you get a new rom and/or kernel installed to reset the battery stats (can be done in recovery) then use it till it dies then charge to full before turning it back on.
Personally, I've been using Fresh 3.3 w/ the Kings #6 kernel and not only has the phone been screamin' fast the battery has been good. I'm only on my 2nd charge up though so I still have one or two to go before everything smooths out.

As posted here, the tests showed that CM w/ Snap 7.5 probably has the best battery life - and it seems by a lot.

[ROM]CM-B2_Supersonic-XV a.k.a [email protected]$T(SuperMOD) UPDATE#5 w snap 7.5
I'm using the latest Fresh and I just plugged my phone in at 15% battery after 37 hours. I'm pretty happy with that.
Fresh Rom always gave me good battery.. I'm just using the rooted stock OTA and am getting great battery life.

Until someone takes the time to make a section that covers the different problems. Battery problems, Battery Problems w/ ROMS, Apps not loading, etc. etc.

I think it would be a great idea for this kind of stuff to happen. Some aggregated source where everyone can submit their information using various roms, kernels, etc. Whether it be information regarding Quadrant scores, linpacks or battery life. On computer hardware forums they generally have a section dedicated to OCing records with charts listing someones entire setup while attaining the clock speeds. I don't see why a similar implementation can not be done here.

i use Fresh's Rom made my battery life live avg abt 15 hours
Over 40 kernels were tested and benchmarked in 7 different ways, and the results are posted here.
Should tell you everything you want to know, without bringing roms into the picture (since battery life is most affected by the kernel used, not the rom)
edit - looks like I'm a bit late withthat link - I see the thread for that site was already posted above. It's a great resource.
Fresh 3.2, hands down best battery life for me. 3.3 was pretty bad, as was myn's release....which sucks, because myn's rom is otherwise awesome.
I am using Fresh 3.3.0.1 with a baked kernel that is able to over clock. I then have SetCPU installed with profiles for different states of the phone. If my screen is off I have the cpu set to a max of 500MHz to save battery if there are any processes running in the background. I then have my cpu set to 1119MHz when the phone is plugged in or at 100% with the screen on just because I like a snappy phone. Then when the battery drops below 50% I have it return to stock speeds.
I use my phone heavily for things like subsonic, QIK, FB, Calendar, wireless tether, and of course since unlimited data, calling to any cell, and texting I am on it a lot keeping in touch with friends. I also use the sprint nav at least twice a week.
Results will vary from user to user but so far the phone has been on 7 hours and after some moderate use it's only down to around 75% on the battery.
Again this is how I MYSELF use my phone with this rom and kernel this may not be how you use your phone and you may see different results.
What I have done is searched roms and installed them in total I have used 4 different roms. Baked, Cyanogen, Fresh, and Virus. After installing each rom and setting up my phone I made a nand backup of each so I can flash between them as needed to test. I have found out of all of these roms Fresh 3.3.0.1 with a kernel from the baked roms has worked the best for MY daily use.
I had an idea as I was finishing wrapping the last of my Christmas gifts .
I went straight scientific method with this one too
An app needs to be created that will put a constant, equal load on our phones CPU's and with this will be able to accurately determine which kernels are going to give us the best battery life.
Here's where I'm going with this:
You change the setting on your phone so that the screen stays on and put your phone into airplane mode after a fresh flash of a ROM and the desired testing kernel. You make sure that nothing else is running on the phone asides from this app. Run the app until your phone dies and compare with other kernels. Granted, this wont be the same for every kernel-rom combination but I think that it is a good starting point as for some kind of "battery benchmarking app" that we could use to try to determine what is going to work best for the ROM of our choosing.

i think its a beast idea.
Battery/Kernel stress testing...hmm.... love concept but too many other variables to base results solely on kernel. Maybe possible if those many variables can be taken into effect or results from many different phones, batteries from different manufacturers, different size batteries, etc are averaged. Another issue is that not all kernels are built for battery life..ie..concept of BFS and CFS based kernels.
Great idea and I think this is possible but again variables need to be taken into mind.

Maybe a stripped down battery testing rom. No radios so that signal strength won't affect the results. Maybe you just run it and see what's best for your specific setup and forget about averaging.
Something very similar has already been done. If I can find the http I will post it. To do what your saying sounds like it would be extremely time consuming and possibly harmful to the phone, depending on the amount of stress you put it under for the time it takes to drain the battery.

We just need a Prime 95 for android now!
I think you'll run into a problem since different phones handle kernels differently
Just install System Monitor and Battery Info Widget. You can see from System Monitor accurate CPU usage (a little over ~1% idle should be typical) and from Battery Info Widget how much mA's that usage is taking (between -40mA and -120mA is typical for 1%).
definitley seems like a great idea
So I recently installed Aliendroid, a rom that uses a modified cm10 kernel as well as running moddified aosp and cm10 hybrid. The battery life on my friends galaxy nexus, both of us have verizon, has been consistently 30% higher and I am curious as to why or how this can happen. Thanks ahead of time.

Is your friends stock? There are a million things you two could be doing differently. Your post needs more information
No he is running the exact same version of Aliendroid as well. As far as I can tell, I have more widgets on my home screens and we even have the same radio version...Hope this helps.
Your friend's battery is better than yours! PROBLEM SOLVED!!!!! lol
It could be different things. Check the battery usage to c where is the difference between ur phone and his/her phone.

However, he could simply have a better battery than you. Download betterbatterystats and check out what's taking your battery life on stroll.
Thanks for the input. As far as we can tell it doesn't seem to much of a difference with programs running. Is it possible that his battery just discharges better than mine?
You cant compare the battery life between two phones with so many variables. The only possible way you could even try would be:
having the exact same ROM/kernel
exact same settings
same carrier
exact same location at all times
exact same apps installed with exact same settings
EXACT same usage <---impossible
I just installed this http://www.intersectraven.net/huawei-watch/ kernel so i have no stats to share. I was hoping someone else had some statistics on its performance and battery life. If not I will report back my experience.
Edit 1 - after 1 day no crashes and performance seems smooth. I didnt notice any better or worse battery but there seems to be less options for the CPU governor. When using powersave governor the battery life is pretty great but of course the UI struggles. The only governors available are userspace, performance, ondemand and powersave

i got reboots from Skin's even after setting things as suggested throughout the thread. I do not see init'd mentioned in the change log for Intersect's but i'm not technical enough to say that it isn't there simply because of the change log. I'm also using his February 2nd version which isn't even listed on the link i placed above (you can find many versions by clicking the parent directory link).
not really a point in installing any custom kernel now since 6.0 is about to drop any day now.

all about one's perspective. I can repsect that but i want better batter and performance every scond i have my watch and it literally take me less than minute to intall it so ill keep tinkering until it drops (could be weeks). Either way, id also like to know which dev to focus on when it does drop and this one seems to update pretty frequently so it may be likely that this one's is ready before Skin's. Ill try both though, you can count on that!!

No. My point was that the custom kernel won't work after the update. I used invisible kernel the whole time but now I hate wait for 6.0 and hopefully the kernel will be updated.
