So, I am one of those unfortunate people who, whenever they flash any new kernel...ever.. at ALL. they get stuck suspend process that kills the battery. it never failed.

I recently installed (as of 2 weeks ago probably) MikFroyo 4.1 and left the default kernel on there that came with it. used it without issue!. first time in forever, I had unlocked framerate, good battery, and NO SUSPEND issues!.

Then you go and release the HTC #15 with SBC.... and I flashed, and it was good says the holy doctrine. Thank you so much for this.

one thing though, while I am getting a better charge hold then before, (10mins off phone=first percentage drop as opposed to 45secs off charger.) I'm wishing I got better. should I just give it some more time?.. right now it's good, any chance of adding some undervoltage awesomeness?..
[EVO 4G Android Development] mshnayde:
I have tried to understand all of this over the last pages , but seems like there is no consensus. I usually keep my phone plugged in in the car to stream music and Navigation. Which kernel is the one to go with. I have a 003 EVO with seidio 3500 mah battery. Don't know which kernel to go with.

Right now running the 4.2.2 more havs v7. is SBC 15 better? or 131? I am confused with this BUMP vs. trickle talk and it's effect on charge and simultaneous usage.

Thanks.
[EVO 4G Android Development] dahauss:
Something like that BUT I think the version of BUMP in the new kernel works different as I woke up with more voltage the what you get on default charging method. Looking at the graph for the stock charging method, VS bump in this kernel, I think it is not letting it EVER drop to 90% before recharging...

This is where I am confused.. I am also told from someone in this thread that if you plan to use the phone while on the charger, BUMP is the way to go.. NOT to mention that ZIGGY's post says it is BAD to leave constant voltage on the battery and that it could have BAD results (burn, explode, etc)..

I just dont know what any effects of either of the charging methods are. I will say I am now testing BUMP.. I left the phone on the charger all night SUNDAY.. took the phone off the charger at 9:30AM yesterday (Monday). Its now 1:26AM TUESDAY and the battery was only at 65%.. HOWEVER this was only with 2-3 phone calls, email checking and tapatalk and a few other small programs ran. I think that is pretty good.. Now Tuesday (today) I will see how it works on real use (since its a work day for me). I want to see how it performs using it the way I normally use it.. Will keep everyone informed...
[EVO 4G Android Development] dahauss:
You should be getting more then 10 mins off the charge before the drop. HOW long are you letting in charger after the light turns green? if using trickle you want to wait until it is at 0MA before you take it off...
[EVO 4G Android Development] dahauss:
what about ZIGGY's post about keeping constant voltage on the battery?? so far (only 1 day of testing), BUMP seems good.. I did have 131 as well with awesome results BUT I use the phone when on the charger and I am told 131 doesnt compensate for that...
[EVO 4G Android Development] soundwavedj:
Is the new v7 HTC 15 a BUMP or TRICKLE kernel? I did not see a description in the op
[EVO 4G Android Development] casper97ta:
honestly it doesnt bother me if it drops a little if im using it while plugged in. The only time I use it on the charger is for some phone calls at night while its charging. I dont use it in the car for anything. And ive noticed that if i am on the phone while its charging i still get positive ma's so I really dont see the down side too keeping 131 with trickle.

It seems that every ones phone/setup responds different to each one of the different kernels so im gonna stick with what works for me but I think for new people coming into this thread they should really try all the different versions to find that sweet spot.
[EVO 4G Android Development] smittycg:
Use #15 v7 on EVIO Rom I am seeing the best battery of any kernel
[EVO 4G Android Development] ejc1214:
I downgraded to #131 and my battery seems to be doing real good now. I got about 16 hours of light to medium use and still 52% left.

I think the charging is working fine now as I am fully charged and the battery monitor shows 49 mA to 0mA after reaching 100% and stayed at 0mA for about two hours before I took if off the charger. That is what is supposed to do right?

From what I understand #131 is trickle charge right? Which kernel is actuallya bump charging kernel?
[EVO 4G Android Development] rushco:
I know that if you read the first 2 posts all your questions will be answered.

Edit. 1st post says as long as you get no negative ma you are good. 2nd post says v8 beta is for bump charging. It is even in bold.
[EVO 4G Android Development] drig:
Smartass Governor

This is also what is in #131

It could be the difference that people are getting really good results with it!

Smartass Governor

This is an integrated process that basically does something like SetCPU does but smarter. What Smartass does is it learns from how you use the system ( the system being your phone ). So SetCPU has its "profiles" to determine how it will set the CPU ( for lack of better terms ), smartass will automatically distribute power as needed. And again this is determined by how you use the phone. Its more of an Intelligent SetCPU. This process is not in every kernel, so if you are interested look for it in the features.
[EVO 4G Android Development] dahauss:
BUT what if I am running setCPU with SMARTASS set in the settings?? isnt that the same??
[EVO 4G Android Development] dahauss:
I use my phone in the car all the time.. I have it connected to bluetooth speakerphone and I also use GOOGLE Navigation as well. Sometimes I stream online music as well (slacker, pandora, or online radio). That being said, I want the phone to have a nice charger when I take it out of the car.

I am on the second day of the BUMP Charger v8 kernel USING SET CPU with smartass set in main profile and powersave set in screen off (245/245). Its been off the charger since 8Am and 1 call and some email. and I still have 100%
[EVO 4G Android Development] drig:
I feel setcpu can add some advantages.

Test it with setcpu uninstalled for a day and lets see if it changes your results

this could be very helpful to all of us.
[EVO 4G Android Development] 94tbird:
i am running the Kernel#15 with SBC from here and Set CPU with the Screen set to 245 when its of with on demand setting. Its been 4 hours since i unplugged the phone, with a few texts, emails, and light web browsing. I am STILL at 100% battery. I would normally be around 90% by now
[EVO 4G Android Development] dahauss:
131 gave me the BEST battery life ever.. I am just concerned about TRICKLE CHARGE and what I read in ZIGGYS post.. Also wasnt there something about using the phone while on the charger with all the kernels UNTIL V7? I think you had to unplug and replug the charger in to get it back trickle charging. I dont need that.

Now on V8 BUMP with SETCPU .. Off charger 8AM .. 11:50AM and it is on 96% with one phone call and checking mail a few times.

we'll see how it progresses during the day...
[EVO 4G Android Development] 94tbird:
well it took 5 hours and 8 minutes and it FINALLY went from 100% to 99%. God i lo0ve this kernel lol
[EVO 4G Android Development] NewZJ:
/cough

sleeps very well
[EVO 4G Android Development] xlGmanlx:
What kernel?
[EVO 4G Android Development] dahauss:
OK so I am testing v8 bump here at work.. OFF CHARGER at 8AM and left for work.. now it is 12:45 and the battery is at 95% .. Two phone calls and checking some email. Guess that is good since I usually start less then 95%. For those of you with the LONG time between 100% and 99%, what are you doing with the phone?
[EVO 4G Android Development] Brian Rubin:
Might I ask what you might've done to achieve these results? Such as which ROM you're using, settings and the like?
[EVO 4G Android Development] dahauss:
WHY do most battery use photos NOT SHOW ANDROID SYSTEM as using any battery? mine always does? do people NOT have widgets etc or anything on their lock screen?
[EVO 4G Android Development] HondaCop:
Did you use your phone at all during this time?

Sent via my EVO from the backseat of your Momma's SUV.
[EVO 4G Android Development] dahauss:
thats what I ask all the time in this thread and never get a straight answer.. MOST people are ONLY looking at the battery life while the phone is sitting idle. I would like to see people compare kernels and charging methods while actively using the phone with normal use, bluetooth, etc etc. Also, from the looks of some peoples battery stats, it looks as they dont even have widgets installed (except the battery one) or have things installed onto the lock screen or any background tasks running or even internet turned on full time etc... I saw one with juice defender installed..

I really, and I think everyone else would to, love to see REAL USAGE STATS.. Just sitting idle is great but using it is another thing...
[EVO 4G Android Development] smittycg:
I am a heavy user 5 screens of widgets, constantly online, play a couple of hours of games a day, Pandora at work.

I see about a 3 to 4 hour increase which is finally enough batt to make it till bed time.

3500 batt

Got 7 hours of awake time 15 hours standby with 10% left this weekend using EVIO ROM with SBC 15 v7

Really odd little quirk...

After updating to Myn's N9 (1/4 Nightly) and SBC-HTC-15 kernel, my PRI will no longer update...let it go 10 minutes and still shows updating....rebooted, tried again, nadazipzerobupkis....

Anyone else have this issue?

:confused:

[EDIT - 8 reboots/tries did the trick...updated Profile...]
[EVO 4G Android Development] HondaCop:
+1... I want to know real world usage, not idling usage. If I leave my phone unplugged overnight, it will use about 5% in 8 hours of idling. This doesn't say much.

I'm not sure if this happened before or after I flashed #15 but I'm guessing after...anyways all the reviews are gone from the market...anyone else had this problem? All of them look like this.
[EVO 4G Android Development] Genuwine1976:
I have download both the more and less havs 12/25/10 kernels and they both say that they are more havs so the less havs is is not the right one... I would like to know if the htc #15 v7 is better than these two......
[EVO 4G Android Development] casper97ta:
I might have to try the bump charge just for the hell of it and see how it goes. I run setcpu conservative and a screen off profile. Im not even sure if setcpu is really making a difference or not but i like having the screen off profile set up. I do plan on using the phone in the car a lot more in the near future so the bump charge might have to be the one i go with when that happens.
[EVO 4G Android Development] casper97ta:
Im pretty sure the results he posted are with the phone in airplane mode

What kernal you using
[EVO 4G Android Development] 94tbird:
Azrael X 3.0 Rom

I said in an earlier post Kernel #15 SBC from this thread.

Yes I am using the phone. Text messaging, a few emails, I played 1 race on need for speed shift and took 2 calls, about 5 min each.

Other than the kernel, I have Setcpu with 1 profile, on demand, to scale the cpu back to 245mhz when the screen is off. nothing else.
[EVO 4G Android Development] mshnayde:
So what do you guys think.

131 or the new SBC ?

Maybe get a poll going?
[EVO 4G Android Development] EvoN00b:
So I've been trying ti install this kernel. I boot into Recovery, wipe cache & Dalvik then go to install the kernel from the SD card and keep getting this error....

I'm currently running the EViO ROM with the kernel that came with it. Any help would be appreciated!

The zip is not signed, turn off signature verification in your Recovery
[EVO 4G Android Development] jefbal99:
So I got an interesting effect from switching to this kernel, I got an extra 10% battery life. When I booted into recovery, I was at 33% on the Widget. After the wipes, flash, and reboot, I'm now at 43%

131 - no wifi while on phone

I've been using 131 v7 for a while, but I just noticed that my wifi drops off while I'm on a phone call. Once I hang up the wifi connects back up again.

Anyone else noticed this?

You are the man! Thanks! :)

Crud, I didnt notice there was Sense version and ASOP version. I loaded the v8 with Sense. Is this going to be a problem?
[EVO 4G Android Development] dahauss:
I think there is only one V8 which works with and without SENSE. Im running it.. its also BUMP..
[EVO 4G Android Development] djnarcotics:
cant the zips be signed with signaptic off the app market ? or will the same error still occur
[EVO 4G Android Development] shaun0207:
wHAT DO YOU GUYS THINK ????

My battery life doesn't seem to have improved at all on HTC #15 SBC v.7 either. Take a look. I am noticing that at as soon as I connect my charger, I drop to 0mA.

BTW: I've made no phone calls today at all! I texted about 7 messages and read 4emails.
[EVO 4G Android Development] 94tbird:
try a new battery ill bet yours is toast. You guys cant let them discharge fully you will KILL them
[EVO 4G Android Development] shaun0207:
I was thinking the samething about my battery. I have a extra one. I use a Seidio charger to charge that one.
[EVO 4G Android Development] kidrobot978:
Is the htc #15 v good? And does wifi

And 4g work also this works with sense noob with the evo

Hows the battery
[EVO 4G Android Development] Product F(RED):
Can you make an SBC HTC #17? It works with Myn's RLS5 Nightlies, which is based on 3.70 OTA. The trick is to flash the 1.77_003 PRI if you don't have it and then the 09.11 radio and then the HTC #17 kernel.

Results for v8 bump charge with CM 6.1.2

Ok....I wanted to take some shoot me pictures...but my phone died way too fast for me to take them. I took it off the charger at 6 AM and it completely died at 3:13 pm today. Since I don't have pictures to show. I will try to "guess"timate the usage amount.

Texts: ~ 40

Surf the Web ~ an hour in total

Emails ~ read 18 and returned about 20

Phone talk time ~ 2 hours total

Angry Birds (lunch) ~ 20 minutes

Bluetooth (connected to car) ~ two hours total

3G has been on the whole time - from 6 AM until 3 PM

I guess I am a moderate to heavy user. And here are my results. I apologize about not providing with any snap shots. But over all I am a fan of the v8 bump. I just wish the phone slept a little better during screen off. I was using SetCPU - interactive 998-384 (main) & powersave 422 - 384 (screen off).

I still hoping for a better battery life. But the performance is great. No lag, with quad scores ~ 1580.

P.S. I am using the stock battery (non-extended)

Anyone have an issue where u charge fully and then after u charge and use this kernel ur system sounds get really low like to the point where you can't hear then
[EVO 4G Android Development] Abracastabya:
WEAK! #15 blocks/hides user comments in the market for me...sucks because everything else about it rules.
[EVO 4G Android Development] Product F(RED):
Uhh...the kernel has nothing to do with the market...It just controls the hardware of the phone.
[EVO 4G Android Development] strauss0829:
will it affect system sounds gettin lowered in volume like keyboard clicking aound and lock sound ???
[EVO 4G Android Development] Abracastabya:
Uhh no...everything was fine flashed #15 then market was effed...this happened 3 times after full wipe.
[EVO 4G Android Development] Product F(RED):
Believe what you want to believe. I have experience with this stuff. Kernels don't mess with applications. I flashed HTC #15 many times (I'm on 17 now) and it does nothing.
[EVO 4G Android Development] Abracastabya:
Well then you should know that not all phones are created equal so what works on yours might not work on mine.
[EVO 4G Android Development] Product F(RED):
It would work because it's made for all EVOs. Stock HTC kernels always work. Do you understand how a kernel works? I'm not calling you an idiot. Not even the kernel. Do you know how the phone actually flashes the zip? Inside the zip there's a text file called update-script. It tells the phone what to do with the files. Nowhere in that script does it say to hide the comments. I don't that's even possible unless you edited the market APK. What ROM are you on?
[EVO 4G Android Development] Abracastabya:
Yeah i have basic knowledge of how all that **** works and what goes on behind the scenes...but despite the way things are supposed to work im going the route of process of elimination...everything is fine and untouched...i flash sbc #15 and comments disapears...this happens 3 times so common sense tells me its the kernel...i dunno makes sense to me...im using mikfroyo 4.2 by the way.
[EVO 4G Android Development] gpz1100:
Can't you just delete the market and reinstall the apk from the ROM?
[EVO 4G Android Development] NewZJ:
I think it was with v8 I wanted to check it's standby times because I thought they weren't as good, in pure standby with juicedefender clicking the data on and off with default settings and keeping cell signal on it did just under 8hrs to 99%

not real world numbers at all
[EVO 4G Android Development] Abracastabya:
Worth a shot.

Any truth behind this Kernal making your Camera Mega Pixels only 3? That's what someone on Android Central was talking about. I hope it's not true, I love this Kernal (I'm running the very aggressive one) and the battery life has been amazing.

But please, any info on the camera would be greatly appreciated.

I am almost positive that this question has been asked, but I truly don't want to wade through over 3500 posts...

Which of these kernels would you recommend for MikFroyo 4.2? I currently have 4.2.2 non-havs and I have not seen a difference...
[EVO 4G Android Development] dahauss:
Ok so using the BUMP CHARGE version.. I took phone off charger 8AM and went to work.. now its 1:04AM ... a long time off the charger and I am at 36%. Here is what I did with the phone:

* Market - update about 5 apps

* check email during the day and evening

* check facebook

* take about 3-4 calls - about 20 minutes total talk time

* 2 text messages received

* run a few apps (groupon, best buy, etc)

* run 2 apps to clear cache and run system panel

I think that is good battery life.. Normally I would put it back on the charger when I am at work and also when I get in the car. I didnt today..

One question.. Is there any plans for any additional updates?
[EVO 4G Android Development] joeyldev:
Just wanted to drop a quick thanks for SBC HTC 15 v7. It's giving me the best battery life in a long time. The only one that came close for me before is HTC 17 stock.

I'm on Myn's Warm RLS 5 Beta 1/4/11. It's a great rom for battery life and the combo with SBC is awesome. Linky for those flashaholics that haven't tried it :) http://xdaforums.com/showthread.php?t=793471

I just want to say thanks for the mod and most of us Evo owners really appreciate the mod. Don't let the Incredible users get to you. I just read a lot of their posts on your mod and I think their crazy. This modded kernel is awesome and haven't battery life like this in a long time. Keep up the good work. Thanks
[EVO 4G Android Development] Brian Rubin:
So I've been using SBC for a few days, liking it so far though I still think I need to tweak my EVO to get beter battery life, when I see all these folks talkin' about ZenDroid and how awesome it is. Being the curious sort, I flashed it to see if it was better, thinking I'd also give it a few days to try it out.

Welp, one hour after flashing it, I got a random reboot, which hadn't happened within days of using SBC, so I wiped the caches and went back to SBC, thinking I should'a stayed there in the first place. Lesson learned. :)
[EVO 4G Android Development] uget2seconds:
i dont know... i know for a fact that i have flashed the right zip however when i go to about phone >> software info

it states that its a more havs kernel... which is the first one i ever flashed from MS
[EVO 4G Android Development] EndlessDissent:
Not that it will probably matter to you since you got a random reboot and probably wouldn't try Zendroid again regardless, but the Zendroid kernels have the SBC mod included in them, so you never really left SBC.
[EVO 4G Android Development] thenewguy821:
MS,

In the 2nd post (the dl list of the kernels), for v8, you say, "This is what I've been testing for a while. This build contains auto bump charging based on the voltage as opposed to the full charge method.". I have tried looking through the posts, but can't find any information explaining the "Auto Bump Charging". Is there any way you could add to the FAQ a description of what the Bump charging is, and how it differs from the standard bump charging that the phones already do? Also, do you plan on adding the Bump Charging to any other Builds (Netarchy 4.3 for example)?
[EVO 4G Android Development] dahauss:
That is the same question I asked and it appears NO one besides me and maybe one other person is using th V8 BUMP. I was using 131 and then V7 but after reading ZIGGYS article on what can happen if you leaver constant voltage of any amount on the battery, I switched to the V8 BUMP.

I hope someone else who uses bump can share their thoughts...
[EVO 4G Android Development] mgianni19:
Yeah, I'm lazy and didn't even think of that :)

I just checked the settings, still at 8MP, and I'm happy.
[EVO 4G Android Development] 94tbird:
far fro ma god i can assure you. eery phone reacts differently to kernels because there are so many hardware versions too

I am on one of the rare 003 hardwares with the new camera chip

I havent been able to use anyones kustom kernel like netarchy or ziggys due to it breaking the camera or the wifi, or both.

This left me with the HTC kernels. In order of best battery life

1. #15 with SBC

2. #15

3. #17

4. #10
[EVO 4G Android Development] dahauss:
** I'm not picking on this guy or anyone in particular BUT this is one example of why I keep asking for REAL WORLD TESTING and NUMBERS. It appears to me that everyone picks a kernel, then gives us the time from 100% to 99% while the phone was idle and then tell us later how much battery life is left with photos and its of either IDLE or AIRPLANE MODE or nothing but what the phone comes with (and maybe not even that) is installed.

This kernel thing is great but MY GOAL is to get the best USAGE BATTERY LIFE out of the phone without it being laggy... so far so good with V8. I have a LOT of stuff installed and I use my phone a lot so my tests show battery life from daily usage....
