I know that one doesn't currently exist, but does anybody know if anyone's actually working on one? Given the age of the EVO 4G, I worry that developers no longer care enough to actually work on this, but it's something I desperately want. I haven't seen anybody talking about it in a while.
If nobody's working on one, I may start looking into how hard it'd be to develop my own (I have some comp-sci background, but being that it's limited, I know it'd be easier for someone else), or offer an incentive to some developers...
And before you say "AOSP!" I say "I love MikG!" I get fantastic battery life as it is, but it would be better if the battery was completely charged when I pull it off the charger. I'll switch to AOSP when ICS is stable on the EVO 4G (because we all know HTC is never going to push an ICS update for the EVO 4G, as sad as it is to say that).

Wouldn't get your hopes up man. SBC is really the main thing I wanted out of the GB sense kernel (along with HAVS and such) but none of the developers are really updating the kernels anymore. Lithid has done an amazing job with his Freedom kernel but he went to the iPhone I think and dropped development before implementing SBC.
I already get terrible battery life on Sense roms (due to a random bug causing extremely high display usage all the time that kills the battery, very frustrating) but maybe SBC will give me a few more hours enough to use it as a daily. Until them, I'm stuck using CM7 which I wasn't a big fan of before but after having to use it so long I have found ways to make it exactly how I want, along with giving me great battery life.
With ICS coming out, I doubt there'll be much more dev work on GB kernels

HTC made the kernel not play nice with SBC the one SBC kernel that was out had lots of issues and was pulled. There was a code conflict in the core of the kernel source causing all kinds of failures with hardware, they went away after flashing a new kernel, but touch screen was whacked out audio bugged and there were lots of FC as the SBC code basically broke the kernel's functionality, so blame HTC not the devs it was like HTC intentionally built the kernel to block SBC. There are kernels out with AVS and I think one with HAVS but I'm not 100% sure on the HAVS since I've been working on AOSP the last few weeks and have taken a break from sense.

Many valid points... thanks everyone for responding. I didn't realize that there were issues with HTC's kernel as it was (last I had heard, the newest GB kernel from HTC had a form of SBC built in, and after HTC released the code, it seemed as though nobody was working on the kernels anymore). I'll have to contemplate thoroughly on what to do... if the developers have looked into it, I doubt I'd be able to make progress where they were unable to do so.
ncfastls1, have you tried MikG at all? I know hardware varies, but it is without question the best performing Sense ROM I've had, in smoothness, functionality (Sense 2.1 + 3.0), and battery life. Using Freedom's more aggressively undervolting kernel gave me camera issues (phone would freeze and reboot), but as you can see from the pic in my first post, I've gotten some incredible battery life from MikG with the less aggressive kernel. I can also provide spreadsheets with my battery life every day that I've had it (I'm a statistician by profession, so I test everything I can collect data on just to make sure I'm getting the best performance from my phone). [Note: When I updated to 2.61, I simultaneously updated a bunch of apps, and my battery life fell off the Grand Canyon, so I restored to 2.60 and am trying to isolate the source of the drain by progressively updating apps before updating to 2.61.] CM7 is great - I have it on my Nook and am anxious to see CM9 - but I do have an affinity for Sense.
Thanks again, everyone!
P.S. I was also heartbroken to see that lithid went over to crApple. He had tried throwing together an SBC kernel (it's buried deep in his kernel thread), but since I didn't see a single person report about its functionality, I was reluctant to try it...
Lithid was working on it for a very long time. He has since gone to the iOS. Wish he wouldnt released his v 0.95 kernel though before he did.
I get 2+ days (max so far 3.5 days) with normal use and Tommy's classic paired with aggressive freedom.

Hello everyone,
Complete noob here tried doing some searching and lots of reading but I could not quite answer my questions. I have an Evo running the just released root (plain default ROM?). I am looking to install a new ROM/Kernel and my primary focus are:
1. Stability
2. Battery Life
3. Performance
4. Features
There are a TON of ROM and Kernel releases and its more then a bit confusing. I've been concentrating on the CM6, Fresh, Evio and Backed Snack. I was planning on using CM6 (it seems highly respected and optimized for stability and speed) but I use 4G all the time and HDMI now and then.
At least at this stage in my research I had Fresh 3.2 as my second choice with Evio/Bakedsnack tied for third (again this is not a review and strictly based on just what I've been reading about these and my take away impression at this time). I don't mind playing around with these to find one that I like but I wasn't sure which Kernel I should use. Are there particular ROM + Kernel versions that are highly respected (keep in mind my priorities above)?
Anyway thank you all for your time and assistance
With your requirements I would recommend the stock 2.2 ROM with the netarchy toastmod kernal. You can get Titanium Backup and go to settings and enable "Chuck Norris" mode to delete some of the Sprint Bloatware you don't want. Just be careful not to delete anything that you don't know what it is (Google Talk is a good example since it controls your market downloads). If you insist on a custom ROM go for Baked Snack with the matching netarchy kernal. It's a nice Rom.
Haven't used too many stock ROMS lately, but you're looking for a good custom ROM Baked Snack is a great choice. I use Baked Kernel #5 and get great battery life and also no noticeable loss in speed.
I used CM6 for a while, but wasn't to happy with it. The EVO seems like it is just to complicated for them. No disrespect intended Team Cyanogen is amazing, but there are still a lot of kinks to work out in AOSP.
Hope I helped.

Either fresh 3.2 or evio. I have used every Rom in here. Evio was my daily til Sprint apps were not updating. He is fixing that. But 3.2 fresh is the best Rom I have used to date hands down. I used kings #8 the with it. As for baked snack. He rocked eclair but not so on froyo. Just ran 1.7 pfft waste of 2 hours. Kernel is messed up and so is Sprint tv. He smokes too much medical marijuana when programming lol. Not against a little thc but it shows in his latest roms in my opinion. I have a hard enough time typing when I am that high lol

I have tried CM6, nectarchy's Burnt Dorid, and Virus new Carbon rom, but none have pleased me as much as netarchy's HTC OTA Froyo 2.2 final build.
This is by far my favorite rom, i have been testing a bunch to see what give's me the best result, so far with this rom and with netarchy's 4.1.9 cfs kernel my genius phone flies while being clocked at 1.19, i would not suggest higher then that as my phone freeze's after 1.19, i haven't found a kernel yet that is as perfectly matched to this rom as is 4.1.9. cfs
thanks netarchy, best setup IMO.

Ok so I ran Fresh 3.2 with stock kernel and was impressed how stable (short term heavy use) and easy to flash. I was finally able to flash CM6 but only after running the NAND unlock flash I found on one of these forums. Only thing was that my bench was lowest on fresh followed by the stock and then CM6 was highest. CM 6 is fast and has some cool features but overall it just didnt fit me. I'm going to try fresh and kings #8 next followed by the netarchy suggestion.
Thank you all for your help! I have to say the friendlyness of this community to a new noob is refreshing!
I've tried out many, many ROMs since I got mine and I like EViO the best. Using EViO 2 1.2 Beta 2 with King's #8 BFS kernel.
Going to give EVIO a try next.
This was mostly on 3g with myns warm 2.2 RLS 5.

Yeah but from looking at the graph Jacoballen, you also used your phone, hence the android percentage, a lot more. So that is pretty good with the time considering how much you used the android system.
Yeah, I was amazed. I don't use sbc kernels simply because I don't charge my phone at all. I don't know why my phone doesn't tolerate HAVS though..

I have read and researched hundreds of pages on this site and have flashed a dozen roms and have a few that I keep in backups, but the crazy thing is is that most of the time I leave the stock kernel in place with what was built into the Rom. But if you haven't seen this page before, http://forum.xda-developers.com/showthread.php?t=719763, this is pretty awesome to have for options.
There is a link in there that brings you to netarchy's kernals and there are loads of them in there. I hear a few of them in there are awesome but the crazy thing is is that for some reason a kernal that is awesome on my evo might not be that great on yours even if we'd be on the same hardware version.

i rooted my phone instead of returning it because i would get about 5-6 hours out of a charge. if that didnt work, i was gonna drop in the toilet and blame my kid. turns out my 003 hardware or something internal actually hates htc kernals, but loves NA anything. before the sbc, i would run myn rls4 with more agg cfs and get 2.5 days out of it. since all roms seem to be coming with htc#15 now, i basically yank it right away.
i also use setcpu a lot for profiles, if not, i run calk 1.8 with battery scripts which seems to work. speaking of which, if anyone can assist in finding and editing them, it would be much appreciated
Hmm interesting, I might try that. I'm on 003 hardware also. Your aren't using an extended battery?

Well I have been using sbc for a while now... And my battery gets just as hot as it used to before.
Gangsters arent afraid of hot batteries
Here's my 2 cents about SBC kernals if anyone cares...hahaha
I've been using SBC kernals for a while now and the trick is to be smart about it! If you use one, don't set your CPU governor on performance and set your MIN/MAX to the very MAX because you'll be one of those people we all read about...hahaha....I set my governor on smartass and set my min at 128 and my max at 921, everything run smooth and I could use any app without any problems! Over clocking just to do it is like bragging about benchmarks....is just stupid!
...or better yet, just don't use SetCPU......

There's probably about 2 people who reported sbc messing up their batteries :rolls eyes: . I've been running sbc for months with no issues whatsoever.

I used to be scared of it, but decided to give Tiamat SBC a try about a month ago. Everything has been great. I'm now a believer!
I've been using SBC kernels since the release and havent had any problems what so ever!
I've been using it for months and it works great. I use the battery monitor widget to confirm that is working great. If you actually read the threads about it, you will find there there isn't actually any danger to using it and it was all a bunch of hype about nothing.
I'm indifferent about it, I hear the pros/cons from both sides and really don't care either way. While I have used both SBC and non-SBC kernels, my personal preference is non-SBC. That said, I also only run on the stock battery and have plenty of places to charge my phone both at home, work, and on the road.
If a kernel only has SBC and I like that kernel, I'll use it. If a kernel doesn't offer it and I still like that kernel, then I'll use that kernel. SBC isn't a make or break feature for me.
The choice is yours, use whatever you like. Try them both, it's easy to do.
I used it before it was cool and safe, y'all be posers
Been running SBC kernels since the moment they popped up . Seidio 3500 battery has kept up and hasnt lost charge capacity at all since then either . I swear by them and refuse to go back to a regular charging kernel

Some thoughts:
Given that the "Android OS" report in battery usage was apparently subject to a major, but simple, calculation bug until 4.0.4, I have doubts about its validity as a measure in this kind of test. Are all of these ROMs using the 4.0.3 code as base, or are some backporting pieces of 4.0.4? Furthermore, how would you know if any devs sticking to the 4.0.3 source haven't gone in and fixed the bug themselves once it became known? If I had to guess just by looking at this, Gummynex, Liquid, and Revolution have this bug patched, the others do not. The similarity within and between these two groups is just too striking.
Even putting that aside, I'm not sure I see the sense in measuring anything but total drain, assuming your methodology filters out any variance due to usage habits (screen on, apps running, signal strength). If the phone is left to sleep and nothing else is running, shouldn't all the drain show the nature of that ROM?
Also, perhaps you can elaborate more on why not keeping the time constant seemed like an okay concession, because when the total drain only varies by 1 or 2% over 6-7 hours, I'm not sure how almost a full hour's difference across tests can be considered insignificant.
For example, compare AOKP vs Redemption in your results, redemption ends up looking marginally better. AOKP reads 4% over 7 hours, or ~.57% per hour. Without actually crunching all the numbers, 20 minutes of variance looks like enough to be significantly signficant if all we get for sigfigs is 1% increments.
With all that in mind, my general impression is that most of these roms are roughly the same for battery. I don't know if there is a feasible option to either get a full mAh reading, or to have program log the exact time a certain % level is reached, but both would give much more valuable data, I think.
Also, one of my first thoughts after looking at this was what kernels are these roms all using? It would be nice to see it included; are the devs using the stock AOSP kernels, stock with a few of their own patches, bundling their favorite custom kernel, or even developing their ROM with a specific kernel in mind? I know that liquid is bundled with leankernel, for example. It begs questions: Is there a good kernel complimenting a well designed ROM? A great kernel making up for a crappy ROM? An extraordinary ROM that shines despite a buggy kernel? (All example for conjecture). Hard to say without kernel as a constant across tests.
To summarize, my main critiques of your methodology are:
-Don't see the merits of using Android OS drain vs the total drain.
-Would like to see a standard time used in tests, or if possible, measure the exact time required for x% of drain, or mAh remaining after x hours.
-Would like to see a larger test range to establish statistical significance.
-Would like to see kernel as a constant, since anyone can flash their own custom kernel, and packaging one in a ROM may be a good move, but doesn't say much about the rom itself.
Those are my thoughts on the methodology and the results presented, but I would also like to express that it's very refreshing to see someone actually going to lengths to compile thought-out data on battery life, instead of the dreaded "wow great battery life awesome ROM" posts that litter the ROM threads.
Edit: As far as a more precise reading goes, if you run better battery stats, Menu->More->History->Menu->View Serie gives quick access to a log that I think would be helpful here. I'm not sure what triggers the program to write to this log, but it's pretty well populated regardless. So you could decide you want to drain the battery to x%, and just read off the first time the log shows that level.
been out of the xda scene for a bit and definitely need a new rom
i'm currently on CM9 alpha-6 and get just awful battery life, less than 4 hours.
What rom should i look at for good battery life and a less buggy experience?
also, i'm not very familiar with a lot of the stuff here, but are there any things i can do to increase signal strength, my brother on the 4s on the same network will have service in places where i get no service etc.

on cm9 alpha 6 you really shouldn't be getting battery that low... I could get two days with about 2 hours screen time back when I was running it. Turn off haptic feedback and LED notification and it will help. If I recall correctly the led light prevents the phone from going into deep sleep. Also, keep auto sync off and battery will improve dramatically... Furthermore, most of the newer builds (including the cm9 nightlies) have governors by which you'll be able to optimize your battery life. Anything with one of agat's source built kernels, one of chris41g's kernels or the kuban kernel will do... Just make sure you use a kernel that is compatible with the Rom you choose. however, ics is a "heavier" os than gingerbread, so getting gingerbread battery life isn't likely.
I've used most of the ROMs and I can't say that I notice too much of a difference in battery life on them (apart from builds before source dropped). Maybe an hour or so, but without consistent usage it's really hard to tell... I suppose I would suggest Black, Calk& Venum tweaked or the blu kuban. I'm getting good battery like on black, and the dark theme obviously helps battery... Kuban is also pretty dark too, and Ruj is really involved in his thread. I put my brother on kuban and he's not complaining about his battery anymore so I guess it's better than what he was on before (one of the early ics leaks). Calk and Venum tweaked has calk's legendary battery tweaks so you won't hurt there.
As to your signal strength, make sure you update prl and profile... If you stay on cm9 youll need to use el29 temp boot in order to do so. I know sprint updated their prl so you are definitely on an outdated one if you've been on alpha 6 since june when it dropped... Also mess around with modems till you find one that responds well.
