That's a very good point I was using v8 with interactive gov phone would stay to A 100% then drop 99 like in 10mins but at certain times battery could be like 45 while playing music n browsing and it would just stay there for a while but I'm not understanding how ppl get like a hr before dropping to 99

I am running SBC-net-4.2.2-less-havs-v7 right now. I tried SBC-net-more-havs-v7 and I looking at the battery monitor i was getting a lot of negative numbers so I switched thinking that this would work better but I am still getting negative numbers while at idle. I thought if you have negative numbers the phone is draining too fast right? Also, my kernel info shows 2.6.32.27-SBC-net-4,2,2-more-havs root@paris-laptop #19. Is that right? I thought it would say less-havs..I wiped cache and delvik then flashed zip. I did flash the new #15 to see if the kernels were being flashed and it did change so I reflashed the less-havs. Any Ideas? my history says I am at -108mA to -242mA.

[EVO 4G Android Development] matt2053:
Your observation is keen. "I'm at 90 percent after 2 hours!" or "I get 14 hours on Kernel X!" are completely meaningless statements. Everyone runs different apps and gets different radio signals and their batteries are all different ages and we have different hardware and the list of variables is endless. "Heavy use" to one might be light use to another.

For example, I've tried every setup under the sun, and 9 hours is the absolute max I get. So I know when I see someone posting that they get 14+ hours with heavy use, their heavy is not my heavy. I apparently use the holy hell out of my phone.

I would recommend you search for the best setup for you, and keep in mind that when others report numbers, they are rather meaningless from a technical, analytical standpoint, and that can lead to unrealistic expectations. No setup is going to increase battery life very drastically. If it sounds too good to be true, then it probably is.

That said, many tweaks, this battery charging tweak included, can make a noticeable difference.

Give this a read..

I was going to add it to the wiki just after the first post, but then realized this forum software doesn't support that function.

It's always a power struggle on battery operated devices to get the most performance at the least battery cost. Having greater scaling may reduce the battery cost, but may increase instability since the processor may crash at lower settings (or run too hot and be wasteful at higher ones).

Netarchy, is your code for the havs tables available... Not so much the code, but the values of scaling used for more/less havs vs cpu freq?
[EVO 4G Android Development] Paper Tiger:
I noticed this as well. I flashed SBC-net-4.2.2-less-havs-v7 but the system information is reporting SBC-net-4.2.2-more-havs-v7 as the current kernel. Perhaps there was a naming error?

I m running fresh as well, exactly which kernal should I use? I know I need to use a sense kernal, but which one?
[EVO 4G Android Development] flipper12:
Just so I'm understanding this correctly....

... does the latest kernel #15 that MS just posted on here simply the HTC Stock kernel with the SBC battery mods but DOES NOT contain any of Netarchy's tweaks (HAVS modifications, etc.).

I'm just a little confused what the latest kernels contain and don't contain, the various naming mechanisms that show up on after installing under 'Software Information' (mine shows #2 too), and more importantly, which one would be appropriate for our phones.

Thanks for your time....
[EVO 4G Android Development] Abracastabya:
Same with baked kernel #6. It reads #2 but has been confirmed as 6...old news but just an example...probably the same thing going on here....I flashed 15 but its reading 2

Thank you..
[EVO 4G Android Development] mr.BeBoT:
Just wanted to post this again as it seems like more people are reporting the issue.

I believe there's something in the SBC mod that is causing reboots to hangup (whether you do it from quickboot or shutdown and power in to recovery) After a battery pull it does clear up. I've been on Calk's evio roms and changed nothing but kernels this last 2 weeks and I have been able to replicate it with V7, 131,#15 and netarchys 4.3. I didn't have the issue with V4 (but also didn't get as good a result)

I'm currently trying #15 and it's the FIRST time i've seen -mAs in any SBC kernel. I've rebooted and will give it another charge cycle to see if it was a one time deal or not.

Overall the battery pull isn't too big a deal considering the advantages of SBC. But for us flashaholics it does get bothersome!

So with this new kernel I took it off charger at 11:30 am at 0 ma. 3 1/2 hours later I was at 99% with checking email and facebook. Now its after 5 pm and I'm only on 91% with taking a call, checking email, facebook and tapatalk. This is also using set cpu with smartass and a screen off of powersave.

The only issue I have is when I turn on phone from standby, its sluggish for a minute or two. any way to fix this?
[EVO 4G Android Development] jelive:
Probably have your profile set for screen off to something like 128xxx/256xxx It's the 128 that's probably causing short term sluggishness. Some phones don't handle that low well.

[EVO 4G Android Development] gmramirez1973:
Cannot connect to wifi

I am also using the latest Azrael X and after I flash the new kernel #15 from second post my wifi tries to connect but it does not connect to my router. I was using SBC for Netarchy's 4.2.2 More Aggressive CFS from second post. I saw a suggestion to restore, redownload and install again. So I did that but still my phone keeps trying to connect to my wifi router but does not connect.

p.s.: Both times I wipe dalvik and cache before flashing the new kernel #15. Any ideas. Thanks.
[EVO 4G Android Development] dahauss:
yes its at 128.. 128 works OK if I set the governor for screen off to ON DEMAND or SMARTASS but with POWER SAVE, which is what I am using, its sluggish for about a minute. Is there something I should it bump it up to to keep this great battery life? Maybe change the screen off from power save to something else? I also have a profile for charging that uses ON DEMAND.

Any suggestions would be appreciated.

Hey, thanks NewZJ, that took care of my WiFi issues with CM.

Speaking of CM, am I dumb in thinking there was once a link for the CM version of this kernel on the front page, and now there isn't?
[EVO 4G Android Development] NewZJ:
post 2, v8 it's based on bcnice aosp kernel, there isn't one for the new cm kernel
[EVO 4G Android Development] jelive:
Not that familiar with power save but bet it cuts things even more and combined with 128 is just too much...takes longer to "recover". If it works well with on demand and 128 I'd use that and doubt you'd really suffer any.

Yeah. I know this is a heresy on this thread, but the script in Calk's EViO ROM coupled with Ziggy's latest CFS evo beta kernel, the Dec 19 version, I get GREAT battery life. Of course, there is the initial quick drop right off the charger, but then everything settles down.

Calk has it written where the CPU is clocked at 460 min and 103 max. The way he explains it, the 460 min uses the same voltage as 135 & 280 and the 103 max uses the same voltage as 998.

OK so this morning I flashed the Netarchy Toastmost 4.2.1 CFS BFQ HAVS More Smartass. 11:30 AM the battery was at 0MA .. I took it off the charger.. about 3 1/2 hours later it was at 99%. NOW it is 11:44PM and I am at 52% battery.. I have setcpu set to SMARTASS as the default and POWER SAVE for the screen off. I also underclock to 128. I did mention in another message that the only issue I have is on wakeup, it is slugish for 30-60 seconds but then runs fine. I did use the phone today.. EVERYONE seems to post their battery life was while in standby... BUT lets see some actually usage stats!

I used FACEBOOK, took some photos with the camera, uploaded some to facebook, text messages, email (including sending some photo attachments), tapatalk and a few phone calls. And this is where I am now with the battery (its one of thise EBAY 1800MAH red batteries).

This has to be the best battery life I have seen with this phone.. better the the 4.1 kernel I was using which didnt have smartass or powersave.... This is on SPRINT LOVERS SENSE ROM!

[EVO 4G Android Development] casper97ta:
As far as i know you wont be able to tell until you flash one and then check to see if the camera still works. Make sure you nand backup and try flashing one. If the camera doesnt work then just restore back.

and it works on sense and 004 hardware?? I assume that 15 is based off stock?

Also want to make sure that doing a nandroid backup will backup everything INCLUDING the current kernel? is there a way just to restore the current kernel from the backup should there be any issue with his phone??
[EVO 4G Android Development] casper97ta:
Yes kernel 15 is the stock htc kernel with the trickle charging added. nandroid will restore everything including the kernel. Just make sure you do the backup and you will be fine, if you dont like the #15 kernel just restore your backup and you will be right back to where you were before.

Hello,

I've seen a few other users having the same (or similar) problem that im having on my girlfriends evo. With the #15 kernel, she cannot connect to wifi or 4g and wireless tether does not function. The reason im posting here is because the netarchy kernels work fine and I've seen others who have this issue.

When I installed the updated 3.70 rom (Azreal 3.0), I did the following. Flashed radio, wimax, and nv seperately. Wiped everything. Installed rom. Wiped cache and dalvik. Installed netarchy 4.2.2 more havs sbc. Updated profile and pri

Now if I flash to #15 stock or #15 sbc, she cannot connect to wifi or 4g. Gives an error in the settings menu. If I flash back to netarchy 4.2.2 everything works again. The reason Im trying to put her on a #15 kernel is that her battery usage on netarchy base is terrible. On my phone (purchased at the same time) its incredible. Strange how different phones react so differently.

Hopefully someone on here with similar issues can toss a few clues my way.

Thanks again

I'd like to thank the OP and leave my impressions after running these for 3 days.

So THANKS !

I'm on fresh 3.5.01. Ran netarchies 4.2.2 less havs for a day, the battery life was incredible ( 3.25 hours of light use and I was still at 100%) - nuts. My battery charging voltage was 4.200v - 4.194v, unless I ran scanner radio which kicked it up to 4.207v. I had been at 4.217v with the stock kernel. I would charge with scanner radio on over nite, and that's how I got the 3.25 hours pf battery life at 100%.

I switched to the #15 stock-sbc kernel to see if it would bring my voltages back to what they had been. It did charge it to 4.215v while on scanner radio and 4.202v while not. I now got 3.75 hours at 100% battery with heavier usage. Really nuts.

I had previously tested this battery and it's internal regulator would cut off its charge automatically at 4.38 v . I would like it if there were a method where a parameter could be passed to the kernel telling it what cut off voltage to use.

Thanks again. I just wish I did have to keep the radio on. LOL

Folks...

The only kernel in post #2 (so far) that is based off the 3.70 OTA and has the new drivers for the newer camera chip is HTC#15 one. It also has the added SBC battery mod by the OP.

If you want to try other options try any of the Net 4.3 kernels, which also have the updated drivers for the new camera. He has several options.

Since under clocking the evo to 128 on screen off gives it a lag on wake up and moVing it to 245 for min (384 still max on screen off), do you think this will hurt battery life much? 245 doesn't give any lag on screen off and I still use 128 for min with smart ass on main profile.

"If you start seeing -mA's on the charger at any point while charging past 100%, the charger has turned off and this isn't working for you."

Well, in Battery Widget Monitor, it's fluctuated from -46mA's to 30 mA's while in the charger at 100%. Does this mean it's not working for me?

Also, the phone doesn't seem to know for sure whether it's at 95% or 100%, as it'll jump back and forth between the two if I unplug it from the AC and plug it back in. Is this usual?

[EVO 4G Android Development] NewZJ:
if your unsure if the sbc is working because you see -mA or are paranoid/ocd then unplug the phone for a few seconds and then plug back in, occasionally when rebooting the phone while it's plugged in can cause it not to work but unplug/replug fixes it

v7 is designed as a bump charge so it will show some -mA then +mA to bump it back up

edit: v7 is trickle, not bump it will show the charge as slowing down after reaching 100% dropping to 0mA eventually
