[Q] Opinions: best sense rom/kernels for battery?

hey guys im sure you get these a lot.
anyway, Ive been running CM6 for awhile now but found out my hometown has 4G coverage now and where i go to school will get 4G in about a month, so I have to make the switch to sense for obvious reasons. Im not huge on performance because frankly i'm not looking to blow minds with benchmarks on quadrant, the phone is fast as **** no matter what so im looking for the best battery life. a must for me is that they keep the theme relatively stock as well, some people arent graphically inclined no offense...
also looking for a good stable kernel with good battery life.
currently running burnt droid with baked kernel #6. heard fresh was good on battery but i think his site, geekfor.me, is down, can someone confirm this?
thanks a lot for your opinions

I don't have 4G here, so I can't say for sure how much 4G affects the battery on this rom, however I've been using Ava-FroyoV10. I do know that the 4G works. I have used it once while I was traveling through a few towns that did have it.
Besides 4G, I do use my phone pretty averagely. In my opinion anyway. I'm usually constantly texting, checking up on eBay using their app, having it plugged into the radio in my car for music, or reading up on engadget. Using Wifi or 3G were applicable. My phone lasts from, about... 8:30AM to around 9 or 10PM. I get a good day's use out of it with Ava-FroyoV10.
I don't use any kernel. I did used to have Netarchy's, however the Ava's stock kernel feels better with the phone. You do not get to adjust your CPU Voltage with the stock kernel.
Your best bet is to surf the Roms and Kernels. Find which one you like best, and stick with it.

Myns warm works pretty well for me with the stock kernel.
plus its a damn good looking rom

CM7 Battery Life?

I just root my phone last night and my phone is running at 33° and my battery is geting handed a new one.
Does anyone know if flashing a new.kernel or any tips to conserve my battery?
Any help would be awesome.

Well a new kernel COULD help your battery life, but you'd have to check the specs of the kernel, as some are for performance, others battery life, and ect. But be sure to see if its compatible, and if you find no data on it always make a backup before testing it!
Edit: In addition to a new kernel, turning off your mobile data [3G] when you're not using is always a big battery saver.

From my personal experience, flashing a different kernel like crack. Lol! but most do indeed improve battery life. I have 2-3 kernels in mind that you could use, how ever i use my wifi tether. So i had to go with a kernel that gives my battery life and doesn't affect my wifi, which the other kernels did effect my wifi.
So if you use your wifi tether, and still want to save on some battery life. Try this kernel.
[Netarchy-toastmod-4.3.2-cfs-sbc-nohavs-suv-universal-singed]
If you don't use wifi tether, then go with these.
[sbc-bcnice-stable-v7]
[sbc-bcnice-stable-v8]
[Reminder Note]
It's really up to you if you want to use these, I'm not telling you to do it. Just offering some ideas to help you brain storm on things.. And yes I have flashed the bottom two kernels on cm7 rom, but my cm7 3g was pretty weak, and i do enjoy 4g at work, so i jumped to a different rom.
Got the links, but haven't posted enough to add links in my post yet.

Just saying, I would recommend staying with the CM7 kernel till a stable release since it's still a beta you never know what will happen!

Ummm....yeah. I flashed kernals to cm7 and lost my camera. Can't get it back either. Been trying everything.

Check spare parts and see if you have any partial wake issues

Awesome guys I will most definitely look into it. Because I love cm7 and do not want to get rid of it.
I should probably get back to work, I'll repost back in a few hours. Thanks again!!

Oh and I do have all of the little things down. I have taskpanel, oc widget at 245-576, disabling data, all of it. It just runs really hot and my phones almost dead lol. So hopefully a kernel fixes it.

CM7 is great for battery overall, and Savaged-Zen kernel makes it even better.
I'm averaging double the battery life from stock Sense.
See my sig for links.

Good job replying to a months-old dead thread.

[Q] SBC kernel shenanigans, easy question.

I see devs promoting SBC kernels and quite a few users raving about their SBC kernels, but aren't they supposed to hurt your phone's battery big time? Are they just ignorant or how is that people are still using SBC kernels despite the known, proven facts of how harmful they are? Am I missing something?

Most people have no issues with SBC kernels. Most of the controversy that was brewed up by some people has passed, and they're pretty well accepted now. The main concern with SBC is that it can lessen the number of charges you get out of your battery. Given the price of new batteries, most users - myself included - choose the extra hours now over the possibility the battery will poop out later.
I get much better battery life on SBC, and it's worth it to me. If you're nervous about it, choose not to use them. Only a couple of phones were actually damaged, and that was when they first came out.

What do you suggest I use, as far as a good ROM/kernel setup? Or even just kernel?

I've been using an SBC kernel for about 4 months now with no ill side effects. I test my battery regularly on our machine at work just to make sure, still good.

I didn't notice lag on the Sense rom/SBC kernel combo I played with recently, but it would stall more often than I remember with any other kernel I've used and the phone would automatically do a hot restart to get itself going again. I also noticed my phone would run much hotter than usual. It would often go over 100 F just sitting on the table while doing nothing.
Some people swear by SBC, though. I'll pass on it.

What rom and kernel for best battery

Right now using caulkin 1.5a and stock kernel 1.1. No Los but battery drops so quickly it seems.

Caulkin 1.5a Bare Rom and Rogue Renegade kernel is giving me awesome battery life.

Stock kernel no Los and best bar life but rogue outlaw comes close.

This for me. Just make sure to calibrate.

Calkulin's and StarBurst are both nice ROMs, but StarBurst has been the most stable with best battery life for me.

Funny, this combination drained my battery quickly until I replaced Rogue with stock--now battery life is great. Rogue had worked fine before the most recent Calkulin update. If you have problems I think you need to try the available options or reflash.

Before switching to a different ROM or Kernel, I always go back to stock to make sure I have a clean starting point. This is so easy now this is available > http://forum.xda-developers.com/showthread.php?t=1351761
I am not saying this will solve every issue but its worked well for me. There really is no reason why a certain config should work fine on one device but not another.

I love starburst but battery life winner goes to Calks rom. V1.5a can last me all day with 50% left.

that is now incorporated into my flashing routine as well. Takes about an additional 15 minutes but well worth it in my eyes.

Yeah caulk use to be awesome. Now I'm getting bad battery drain. About 3% since turning my screen on navigating to this Page and replying back.
Going to flash stock tonight and reflash.

I can easily get a full day of heavy use when off charger with calk's rom. Which is nice to know. I might just pick up another battery to have just in case but coming from the Evo this phone is light years ahead with battery. I suggest flashing stock tar and pit file as part of your "wiping" routine.

Yeah I use to also but last two days its been relatively bad. Definitely flashing stock.

What about this one on battery life as well as signal extra...

I UV the cpu and GPU on stock EG31 kernel

after flashing starburst 1.9.5 battery life was great but then getting worse
I had great battery life after flashing starburst ROM 1.9.5 and calibrating, but after a couple of weeks battery life has become 50% worse. What could be the cause of something like this when my settings haven't been changed?
running lostKernelExp+
i installed badass battery monitor and it appears that the application "kernel" is responsible for 30% of my battery life. when battery monitor shows "kernel" is it referring to lostKernelExp+?

Added Poll! Central discussion of ek02. Let's see if it solves LOS

Hello everybody. I updated from eg30 (I only had the phone for a day and had one LOS on eg30) and went to ek02. I wanted to create this thread for all the brave souls who updated to let everyone know if it's worth losing the eg30. I haven't been running it too long... only ~ten hours or so. I haven't had LOS yet. As far as reception, speeds, quality, etc. I have no idea; I just got the phone yesterday night.
Let's try and keep this organized. If you want to report your findings on ek02 please do so in this format:
Previous LOS ~frequency (and Modem version):
With ek02, LOS frequency(if any... hopefully, none):
data speeds/ reception on old modem:
data speeds/ reception on ek02:
Just a courtesy thread for those who are laying back and waiting.
Edit: a few people brought up a good point. Kernel matters! Include kernel observations too.

Would love to see some reports. For those on eg30 that are going to update to ek02 run some speed tests first then update and run more and compare them. Thanks.

Pretty much my thoughts. Hopefully people will actually post their results in this thread to help others who haven't updated

With the EG31 modem and EG31 [or EK02] stock kernel, I have not have one LOS or ghost LOS.
Been 12 days.

I never got them while I was on the EG30 or 31 stock kernel. I would get los at least once a day on every custom kernel.
Today I got los (on the EK02 modem and Lostkernel) but it seemed to happen when the signal was handed off from my airave to the normal mobile signal. Once I left airave coverage I was looking at my phone. I saw it disconnect from it, my bars came back (full) but no 3g icon or data until I rebooted. I just flashed the stock Ek02 kernel so hopefully I wont get it again like I didnt on the other two stock pulled kernels

I'm referring to just the modem:, not the kernel.

Considering that they are both contributing factors (although the modem is more so) they are both relevant

Same here and I went to some known bad spots too and the EK02 kernel with EG31 modem seems to be working really well so far. The kernel does play a role so hopefully we will see some comparisons using same kernel

Yeah Kernel plays a big part f,sure.
LOST kernel los has been out of control , many of its users went back stock kernel finding los to be little to none.
Why thats ignored placing majority of blame on modem is beyond me.

I knew that...(not really ) I'll add kernel to the op. Thanks

I'm running both the EK02 kernel with the EK02 modem. Not one LoS to speak of yet (running since about 1pm yesterday). The bars don't jump around as much, I seem to be getting a better signal. Before this I was running the Rogue stock kernel and had the EG30 modem (of course).
As far as speeds, that's difficult to say given all the variables on a mobile connection. So far though the 3G download speeds seem to be higher, double what they were almost. That doesn't say much when they were 7 - 24kBps before. Now I'm looking at 30 - 50+kBps. Like I said, that could just be a fluke so more testing will need to be done. WiMax has about the same speeds too, was 380kBps average, now it's around 440kBps. - Those are kiloBYTES not kiloBITS for those that get confused.
The kernel seems to be a significant improvement though. Benchmarking scores went up on Antutu, Quadrant, and Linpak. The system had no lag before so without benchmarking you really can't tell.
Lastly, the ROM updates are nice I guess. A few icon changes and the overscroll glow has now been changed to blue, as opposed to the yellow it was before. Other than that nothing fancy or notable has changed from what I can tell.
One addition here, the battery life is very noticeable with the update. For me at least - it drains significantly slower than the previous stock kernel.

I havent had LoS or ghost LoS ever since I installed the modem and the kernel, I usually get 3 a day but 18 hours in, nothing, nada.
I have noticed the phone "snappier" than normal though

Was anybody getting random hot reboots with any eg31 kernels? If you have, did the ek02 kernel remedy that? Others and myself have been trying to solve our hot reboot issue (in Calkulin's thread). We don't know what is causing them for a select few of us.

I flashed the ek02 kernel on blazer rom and still get hot reboots. I've tried almost every rom with different kernel combos and still get them. Got them on stock eg30 and eg31 kernels and modems.

Can you either post here or pm me a list of apps you have? I had these reboots on my Evo 3d and I'm using the same apps. Let's compare the apps that we have... because as of right now, the only variable I haven't tried is a rogue app. :/

I don't think it's an app but maybe a custom script used by the rom developers. The only time I didn't get the reboot is by going back to the stock rom.

If it was a script.... wouldn't everyone be getting these issues? Some are getting it on every single rom too.
If you're on Calk's do you think it's the undervolt?

just updated mine a couple of hours ago, so this may be a bit premature, but I dont really see any increases in network speed. When using the speedtest app the before and after results were about the same. That being said I am at work, where I get a halfway decent signal if I m outside the building. The true test will be when I get home tonight. Aside from network speed being the same everything else seems pretty much unchanged, with the exception of the phone seeming to be a bit more snappy, although it could just be in my head. Lin pack scores did seem a bit higher, but nothing to go crazy over. I have only had one LOS since launch day, so that isnt really an issue.

I just wanted to chime in with my experience after flashing the EK02 modem. I flashed it about 3 hours ago, after I had received 2 LOS at work this morning.. and typically been getting at least 3-4 a day (stock pulled kernel with CMW - Lost kernel was no better)
So far I haven't received any LOS but I've been getting the best 3G speeds I've seen yet. I was getting around 15KBps average in my office (and that is after months of running speed tests!) and I just ran a few tests now and I'm getting ~70KBps after 3 runs. Very noticeable improvement although it isn't spectacular, much more acceptable. I just compared it to my previous speedtest.net result history and it's by far the best speeds I've gotten since I've owned the phone in this same exact location (my desk at work)
Thanks again to everyone involved getting us this leaked firmware!

I don't think so. I was on calks, flashed a stock kernel, took out the undervolt script and still got the reboots.
Again, I never got them on a stock rom, only custom ones.
