Yes, I have been using the SBC kernels for about a week now, and only charge at night, usually for about 8-10 hours. My house is still standing.

I think the 131 kernel on the OP's 1st post is the best one. With what I consider normal usage, after 13 hours of unplug, I am at like 45-50% battery power, which is just sweet.

If you are that worried sleep with a glass of water next to your nightstand, so if it does "catch on fire" you can douse it :p. But most people's battery monitor shows that it never goes above 73ºC nor above 4200Mv.
[EVO 4G Android Development] fenixjn:
Been using SBC for about a month now: no issues whatsoever. I am actually charging overnight and have not noticed any bad side effects. Now on the good side, so far, 2 hrs @ 100% seems good for me :)
[EVO 4G Android Development] SouthernEvo:
I have to agree with the above posters . I to have been using these kernels since they were first made and had no problems . I had concerns at first but after watching battery logs and temp logs religiously , I to feel they are safe and not the cause of the battery failures .

*Lights up a cig* "OMG MY EVO IS SMOKING ! ! ! ! !! ! ohh wait its me nevermind :-)
[EVO 4G Android Development] buck1623:
sbc no charge last night, what yall think?
[EVO 4G Android Development] drrtydisko:
Been using your kernels since day 1 never had over heating issues and I always leave it on to charge over night. Don't use anything like setcpu and my battery is stock. Only issue I ever had was once when the battery was at 0 percent after charging it 15 minutes then it turned off and when I turned it back on it was not at 0 but if I remember well was actually at somewhere around 25-55 percent don't remember but never happened again. Wonderful work.
[EVO 4G Android Development] fixxxer2008:
i get no where near two hours at 100% anymore. i really think launcher pro may be the culprit as i just started using it. do you guys recommend the no havs, more havs or less havs version?
[EVO 4G Android Development] cheebahawk:
People on these forums crack me up, about 90% of us are leechers (i.e. we use other people's work, but dont have ability to create) but so quick to jump on people based on pure speculation.

I kind of went off on this thread here: http://xdaforums.com/showthread.php?p=10456861#post10456861 because people are dumb, MS is having to defend/argue with them, and some idiots are calling for banning MS or the mod, which is stupid!

MS I would just say ignore those idiots and keep up the good work!
[EVO 4G Android Development] cheebahawk:
It really depends on the ROM and your phone. But I have the best success running the More Havs version. You should really try the 131.zip that MS has on the first post. The battery life on that one is AMAZING! With normal use, after 13 hours I have 45-50% of the battery left.

I am running Fresh 3.5.0.1 and on hardware 002, and always seem to get the best results with More Havs CFS than anything else.
[EVO 4G Android Development] fixxxer2008:
i cannot use 131 as i have a 004 evo and i get screen tearing. i have to use 4.2.2. i always though less havs or no havs was better?
[EVO 4G Android Development] cheebahawk:
That sucks, cuz 131 is the best LOL. I'll be honest and say I have no idea what the less, no, more havs really means, but based on personal experience MORE seems to always do the trick for me. It could also be that I dont use Set CPU or anything like that.
[EVO 4G Android Development] fixxxer2008:
has anybody had good results using the sbc #15 kernel?
[EVO 4G Android Development] buck1623:
it was aight, except i had issues with wifi.... which is why i changed over to netarchys 4.3 havs bfs more aggressive sbc kernel... thats a mouthful!
[EVO 4G Android Development] fixxxer2008:
right now im running netarchy's 4.3 no havs, sbc, cfs build. it's ok soo far. im just trying to get the best battery life here.
[EVO 4G Android Development] Cole28:
So I asked this in the SBC flame war in the general forum but didn't get an answer. How safe is this to use with the chinese 3500 knock offs? It's all I can afford atm, and really need an extended battery for wireless tether while at work, and not near a charger.
[EVO 4G Android Development] fixxxer2008:
personally im thinking the cheap knockoffs are what is not playing nice with the sbc mod. oem is the way to go my man.
[EVO 4G Android Development] Cole28:
So would my best bet be to buy an external charger until I can buy a higher quality one? Or could you recommend a kernal that will charge one fully?
[EVO 4G Android Development] EndlessDissent:
I think the problem is USB. No one is saying anything about the charging method they're using, but some people are adamant that they are using the OEM battery. And Vaelek just posted about his own battery dying, and he said he was using USB to charge. I use AC almost exclusively and only had a minor hiccup once, and that was weeks ago.

Edit: I just remembered that the time my battery completely discharged, it was on USB. I think it was the first Zendroid kernel using the SBC mod that was supposed to be made specifically for USB charging.
[EVO 4G Android Development] kf2m:
I am running a Seido 3600, and have seen my available runtime go from 14 to 26 hours according to Juice Plotter. Not bad. The big test is when I go back to work on Tuesday, and use my phone during my train commute (45min), and walk to my office (almost 20 blocks). WinAMP running from the time I leave the house, to the office. Surfing the web/ reading XDA in the train, and maybe a phone call or two. I usually windup with the battery down to 87%. Hope to see a marked improvement.

What sort of Wifi issues are you having?? I'm using the #15v7 kernel.
[EVO 4G Android Development] Agfadoc:
What about the variables in chargers.. some a noisey DC, some are $6 chinese crappoa.

I use a car charger from ProClip, an AC charger from Seidio, an HTC charger, a different USB cable from my Garmin 3790...

Too many variables..

Add to this Manufacturers average defect rate of released products...

131.zip well it work on sense? And on newer model of evo and does wifi and 4g work?
[EVO 4G Android Development] buck1623:
This exactly what i was thinking as well... ive noticed that while trying to usb charge exclusively in my car, if the battery is below 60percent, it WILL NOT CHARGE... instead, the phone becomes hot trying to charge eventually shutting down... then the only thing that would allow the phone to recharge is AC....
[EVO 4G Android Development] NewZJ:
the only problem I ever had with a SBC kernel was due to usb charging, I was testing a kernel he incorporated usb charging mod (before then it would only work with AC charging) and the problem was that if you rebooted the phone while plugged in it would show a charging and the voltage would stay high but in reality the battery wasn't charging at all and because of the false indication it would override the phones ability to turn itself off (it thought it was charging, ya hear?) I reduced the battery to below minimum overnight because I was also testing draining while charging by running wireless tether,i awoke to my phone off and nothing I did made it turn on or show a charging light

later it started working and am using the same battery even now, what I learned is if your usb charging and you reboot your phone, unplug it for a few second after it turns on.

I haven't been able to reproduce the scenario since the upgrade the next day (this was back in the test kernel 70 series)
[EVO 4G Android Development] cheebahawk:
Yeah it works with SENSE roms, since its not under the ASOP builds. Also the kernel has nothing to do with your wifi or 4G radios, so it shouldnt have any effect on them just because you installed a new kernel.
[EVO 4G Android Development] jelive:
Works on sense but for older hardware versions. Need to use one of the newer Net-SBC 4.3 or 4.31 Net included updated camera drivers in these...see here http://www.qap.la/~netarchy/

Jim
[EVO 4G Android Development] dthomas03:
What are normal battery temps?

During charge? Or during idle? When is it not safe? Just wanna monitor the battery a little more effectively.

To OP, I agree with everyone else on here, 131zip (more) is running flawless for me and battery life is great. Finally I can work my 12 hour shift w/o charging! Thanks.

Works on HW 004 but not on 003

This is driving me crazy!

I have two EVO 4Gs. The only difference between them is the HW version. One is 003 and the other is 004.

I rooted both phones and burned on both of them, in this order:

HTC KERNEL #15 v7

SBC-net-4.2.2-more-havs-cfs-v7.zip

On the 004 unit I have no issues. On the 003 unit, as soon as I boot into the ROM the first thing that I noticed is sove very thin vertical lines running up and down the wallpaper. The second, and most annoying thing is that the unit reboots itself constantly. If I go into recovery and flash HTC KERNEL #15 v7 then everything stabilizes.

I just tried flashing SBC-net-4.2.2-less-havs-cfs-v7.zip and so far (about two minutes) ro reboots.
[EVO 4G Android Development] jhuff83:
Badass, thanks Endless. Guess that's a security feature w/in amon. Kind of like with the evo not wanting you to install non market items.
[EVO 4G Android Development] mwielgosz:
Some phones, for whatever reason, do not respond well to undervolting. This causes screen tearing and random reboots. If this is the case, you will not be able to use aggressive (or possibly any) undervolting kernels on that phone. Each phone responds differently...

[EVO 4G Android Development] mwielgosz:
Some people have issues with the v15 kernel and wifi. My girlfriends evo has the same issue. It connects fine, but wont transmit data. I've read that it could be due to a kernel that was packaged incomplete. I've also heard people say there is no known fix. Its possible that someone may have come up with a fix...if they did, hopefully they will chime in :)

I ended up having to ditch the stock kernel and go for a netarchy kernel on her phone as well. Less issues. I find it funny that our xda developers make better and more reliable software than the manufacture of our phones. Thankfully, they exist :)

edit: its the HTC KERNEL #15 v7 btw
[EVO 4G Android Development] trixr750:
this is serious? I noticed that you have 1.77 pri. were you at 1.90 then went back down to 1.77?

reason I asked was to see if the 1.90 does drain the battery faster...
[EVO 4G Android Development] Likeachampion3:
As one of the people who reported major issues/battery failure with the kernel, I wanted to throw a few things out there for the dev just in case it would be helpful.

- I was on USB charging when the failure occurred (seems to be a theme), but the charge/discharge was acting funny all day despite what it was plugged into

- I was using the battery that came stock with the phone, launch day Evo 002

- Per a follow up post, after plugging it into a cheap external charger, the battery is working again though with much reduced performance than ever before. My wife's stock Evo kills mine on battery life now as a comparison, but it is still usable as long as I ensure that a charger is nearby at all times.

I am still confident that the kernel had a lot to do with the failure, though I am sure the USB charging contributed. Either way, the kernel worked great and did what it said it would do up until it failed, so there is certainly something to it and I look forward to the kinks being worked out and perhaps using it again at some point!

Using 131 or v7, my phone got to over 110 degrees while using google navigation with the phone plugged into the car cradle and power. Just tested an hour ride with auto bump kernel and google navigation and the battery mostly stayed between 85 to 94 degrees the entire way. and... When I took phone off cradle, it didn't feel hot like it did with other kernels. I'm sticking with auto bump as I get pretty good battery life.
[EVO 4G Android Development] :
i bumped mine back down to 1.77 - running azrael 3.1 and sbc 15 for 4 days now and battery has improved. #15 on my nova 002 has been the best and i tried them all.

im sure if i used wifi- i would only be at about 90% battery right now since wifi will basiclly get you 4 hours for every 1 hour of heavy use on 3g.

right now im at 13 hours - slept for about 7-8 of those . and at 56% i did use my phone for 2 hours non stop with 4g on right off the AC charger.

MY BATTERY SIPPED ON 1% ALMOST ALL NIGHT. ILL POST UP SOME BATTERY LOG

Yes it's normal, as long as they are not over 100 you are good. It just means the charge is so little that you are using more than you are charging

Whether or not you are skeptical of the damage caused to peoples' batteries by these kernels, there is no denying that they degrade battery life. And I don't just mean day-to-day battery life. I mean overall lifespan of the battery.

I'm using the sense kernel 15 v7

I was using it. Email and music. Nothing took heavy.
[EVO 4G Android Development] :
from what i can see thats pretty good - the thing is you pulled it off and it had a charge of 4109mV when you can have about 50-90 more - plus your cpu sucked up -300mA average for about 40minutes. looks like you stopped using it around 830 - then started again 5minutes later

-558mA is alot IMO. are you overclocked?
[EVO 4G Android Development] webguru4life:
I'm using mikfroyo new rom. Not using set cpu though. Any way I can cut down the mA my cpu is using?
[EVO 4G Android Development] xlGmanlx:

Hey guys,

Just an FYI. I have installed and tried 9 kernels over the weekend and this one I found to be the best.

I am currently using Azrael 3.1, Setcpu @ 1152, JD, and the circle battery mod on hardware version 0004 (just got the phone about a month ago).

I tried

-netarch toastmod 4.1.9.1 cfs havs universal signed

-netarchy toastmod 4.3 cfs havs more sbc universal signed

-netarchy toastmod 4.2.1 bfs bfq havs more smartass universal signed

-netarchy toastmod 4.2.1 cfs bfq havs less smartass universal signed

-netarchy toastmod 4.2.1 cfs bfq havs more smartass universal signed

-netarchy toastmod 4.3 cfs havs less sbc universal signed

-kingxkernel evo 11-2.6.32.24 flashable

-netarchy toastmod 4.1.9.1 cfs- havs universal signed

An the winner is :

-netarchy toastmod 4.2.1 cfs bfq havs less smartass universal signed

All the roms averages about 400mA when the screen was on and idling and when running programs.

When I used "netarchy toastmod 4.2.1 cfs bfq havs less smartass universal signed" the rom was chilling. I average about 100-200mA. My phone was not draining battery life.

This is just a FYI but if anyone tries the kernel, please let me know if you experience the same thing.
[EVO 4G Android Development] webguru4life:
Sounds like a winner. Mine is averaging about 500-400 mA. Can you post a link to the kernel please. Thx
[EVO 4G Android Development] ShawnGotBANDZ:
I figured it out! works for me, stayed at 100% for like a half hour... that's crazy!!! will take it off out with me today to test out the battery life in general... see how many hours I can pull out of it! but I do have one question... Does this work on phones that aren't rooted?? cause my mom has a MyTouch Slide that's not rooted and her battery life isn't as good

Kernel

Hello Everyone,

I am fairly new to this so bear with me. I recently rooted my phone with the latest Unrevoked. I have since put Myn's Warm TwoPointTwo RLS5 and I was looking through Warm Updater when I saw I could put different Kernels on my phone. I thought I would try this kernel, SBC #15 v7 due to its battery savings. My phone rebooted but now it is stuck with the little android and a triangle and exclamation point at a 45 degree angle.

Any ideas?

Thanks.

Jimmy
[EVO 4G Android Development] Smidgers:
Out of curiosity I had a friend of mine track his battery on his iphone. It uses the same charging method as sbc. Iphone should have a long enough track record to prove this method does not severely shorten the length of life for your battery.
[EVO 4G Android Development] DCoop:
Pull your battery and reboot. Try using one of the Recovery programs to install the kernel.
[EVO 4G Android Development] webguru4life:
Kind on topic.

Has anyone tried the battery on the evo shift? If so, how is it compared to the evo?
[EVO 4G Android Development] jimcgov3:
When you say install using a Recovery program, are you referring to ClockworkMod?
[EVO 4G Android Development] webguru4life:
Or RA recovery
[EVO 4G Android Development] jimcgov3:
No matter which kernel I use with Warm Updater I get the exclamation point triangle and Android. So the trick to bypass this would be to download the kernel, transfer to the root of the SD card and then boot into recovery and install zip from SD card?

Thanks

[EVO 4G Android Development] DCoop:
That's right. You also can use your phone browser to go to xda and download it onto your phone. It will go to the /sd/download folder so you go to that folder and move it to the sd card root, which really only means you don't place it in a folder.

Then use a recovery to install from the SD card as you said. Good luck and ask more questions if you have a problem.

[EVO 4G Android Development] jimcgov3:
Can I install a new kernel right over the the new kernel or do I have to go back to the original kernel before installing a new kernel?
