[EVO 4G Android Development] ___DJK___:
been using 4.2/cfs/aggressive/havs/universal/smartass for about a day coming from 4.1.9.1 cfs/agressive/havs/universal.

Not using any setCPU profiles or overclocking, the phone is pretty responsive. I haven't used it long enough to say for certain, but for me, I think I was getting better battery life using 4.1.9.1 using SetCPU profiles. Time will tell.

One issue I had this morning that I have not had in the past is that the phone was very unresponsive and started stuttering while i was streaming pandora on my way to work this morning. I actually had to shut Pandora down. Does the default Smartass settings underclock to 128000 when the screen is off? That always seemed to low whenever I tried it using setcpu.

Anyone else experience this? I saw someone had an issue with Slacker, but Slacker has sucked lately after one of their recent updates.

May switch back to the old faithful or try one of the 4.2 bfs kernals
[EVO 4G Android Development] freeza:
Question: Is aggressive better for overclocking? :)
[EVO 4G Android Development] netarchy:
They should all overclock the same, the difference between more/less aggressive and nohavs is in how much they undervolt.
[EVO 4G Android Development] wfrandy:
I too have had problems with streaming music when using aggressively undervolted kernels. I apparently have a different opinion on what is going on to cause it though. My theory is when the screen goes off and the cpu frequency goes down the kernel starts undervolting aggressively, which in turn decreases the sensitivity of the radios. If you run something cpu intensive in the background, like wifi on with no wifi signal, it could cause the system to keep the cpu speed up trying to find a signal, thereby raising the voltage, which in turn increases the sensitivity of the radios, thereby alleviating the weak signal that caused the streaming music player to drop out. Of course, doing that defeats the purpose of running the aggressively undervolted kernel in the first place, as that would kill the battery life.

Regardless, whether my theory is correct or not, running netarchy-toastmod-4.2-cfs-bfq-havs-less-smartass-universal (Less Aggressive Undervolting), cures the problem for me. On my way to and from work, I travel through about a 5 mile stretch of very week 3g signal. With the aggressively undervolted kernels Pandora stutters, stops and cuts out so much that it is unusable, same results with Last.fm and Slacker radio. With the less aggressively undervolted kernels they run smooth as silk. And I have to say, I can't see any significant difference in battery life between the more and less aggressively undervolted kernels on my phone.
[EVO 4G Android Development] -viperboy-:
Switched from 4.2 BFS Aggressive to 4.2 CFS Aggressive and definitely better battery life already when using it heavily and when sleeping. I'm gonna run this for a few days and see how no HAVS works with the battery tweak and see if it makes battery life even better.
[EVO 4G Android Development] godfirst:
This is with 4.2 bfs more aggressive with moderate use.
[EVO 4G Android Development] achllles:
Did you try CFS?

If you did, how much of difference can I expect?

Thanks.
[EVO 4G Android Development] achllles:
Don't even bother with battery tweak on 4.2's. They don't work in my experience.
[EVO 4G Android Development] vincey2kr1:
Did some stress tests today along with current widget, looks like 4.1.9.1 and 4.2 smartass are running the same ma? Really only difference I see is smartass bounces a lot between 245 mhz and 998 occasionally 614. Were 4.1.9.1 seems to need more cpu load to ramp up the mhz saving me some battery life. But I get better consistent linpack scores with 4.1.9.1 around 38 to 40 were 4.2 theyre all over the place, range from 30 to 38. Both about the same quad scores, fps2d deviation is better(lower) on the 4.1.9.1 .
[EVO 4G Android Development] flooberz:
do you guys normally wipe battery stats when flashing a new kernel? i'm currently on 4.2 more aggresive cfs... coming from the stock kernel that came with fresh3.4.0.1

8 hrs 43 mins of awake time and i'm at 35% battery left.. bout 30 mins of web browsing, good cell signal, maybe bout 5-10 mins of gps usage..
[EVO 4G Android Development] ms79723:
Yea, i wiped my stats for this kernel. Battery life seems to be better so far.
[EVO 4G Android Development] godfirst:
Haven't tried cfs yet, but the way the bfs is looking I don't think I will be.
[EVO 4G Android Development] juancaperez2000:
dummy question that is BFS with havs more undervolted right, imean the once that you are ussing now
[EVO 4G Android Development] halorin:
Man, CM6 RC1+ 5.00 Preview 3 was the smoothest combination I've ever had on my phone. For reason though I couldn't connect my phone as a flash drive.
[EVO 4G Android Development] ms79723:
Hey people, this 4.2 smartass kernel + this has the potential of giving you the best battery life ever. Just a theory of mine, but so far its holding up and its quite shocking. If what i said were true in that post, i just wanna know "why?!"
[EVO 4G Android Development] beerad29:
Net - you are correct. I will try the 4.2 bfs no-havs version and let you know the results.
[EVO 4G Android Development] nuetron:
Successfully pushed the 3 files, bcm4329.ko, hid-dummy.ko, and sequans_sdio.ko to /system/lib/modules. Rebooted and wifi is still unable to start.

4G works and connects perfectly fine. Did speed test to confirm.
[EVO 4G Android Development] persibro:
Sorry for not making it clear. The files pushed, but the wifi is still unable to start.
[EVO 4G Android Development] netarchy:
ok, try this, push the bcm4329.ko file again, only this time DON'T reboot the phone, instead adb shell and from the shell, cd /system/lib/modules and then insmod bcm4329.ko

Let me know if you get an error.
[EVO 4G Android Development] spiicytuna:
good deal! I am not in a 4g area at the moment but was curious if it would work tomorrow when I was.
[EVO 4G Android Development] nuetron:
Pushed, adb shell, cd to dir, insmod bcm4329.ko. No error. Just went back to #.
[EVO 4G Android Development] persibro:
Done, and no errors on my part as well.
[EVO 4G Android Development] netarchy:
Try to enable wifi on the phone, does it turn on?
[EVO 4G Android Development] nuetron:
Unable to start
[EVO 4G Android Development] persibro:
That's a negative.
[EVO 4G Android Development] Auramaster:
I can confirm Version 3.6.2

DOES NOT

work on Froyo... lol tried it on Avalaunchmods EVOlution V9, and it flashed, booted up, but it killed the responsiveness on my touchscreen... So I'm nandroid-ing to Baked Snackv9 and testing it out.
[EVO 4G Android Development] spiicytuna:
Time to change the title to include "does not support dc"
[EVO 4G Android Development] persibro:
Strangely enough, after running insmod, I was able to create an access point using Android Wifi Tether 2.0.5. Then after turning that off, I can enable wifi and connect to my router.

Edit: Rebooting breaks it again, but it will work again after running insmod.
[EVO 4G Android Development] toneman1984:
Can someone post video footage of he/she navigating the homescreen with this kernel? Thanks!

Special thanks go to the developers who are unlocking the potential of a great phone.
[EVO 4G Android Development] spiicytuna:
If no one has by tomorrow I'll do this when I wake up.
[EVO 4G Android Development] nuetron:
I can also confirm that this trick works after doing insmod.
[EVO 4G Android Development] netarchy:
Ok, I made a revision to the Damage Control build, try 3.6.2a from the first page.
[EVO 4G Android Development] Samzebian:
Where can I get build 3.0 to test? All I see is builds 3.5 and up
[EVO 4G Android Development] netarchy:
I think not ;D
[EVO 4G Android Development] netarchy:
http://qap.la/~netarchy/netarchy-toastmod-3-testkernel-signed.zip

Your framerate wont be as high, but the focus is on whether or not the hdmi works with it (as that will give me a clue as to the cause of the issue).
[EVO 4G Android Development] Auramaster:
Flashed it on Baked Snack V9, Wi-Fi works (donno bout 4g, dont have coverage at my house)... Avg I'm getting in the low to mid 50s... stdev getting 9-10.6

Just ran a FPS2D test and got 54FPS & stdev 10.57... On the other kernel, I was getting around 45... So a good improvement...the extra frames are noticeable when flying through the homescreens of ADW and Sense.
[EVO 4G Android Development] Biofall:
That is a well known aspect of the Evo's battery. It does not trickle charge, so once it gets to 100%, it begins to run off of the battery until it falls to 90%, where it will start charging again. The display will show 100% during the entire process though, so if you remove it at the right time, you could actually take your phone off the charger at 90% when it says 100%. This accounts for the majority of the battery drainage initially
[EVO 4G Android Development] ms79723:
So then why are people bump charging? that doesnt make sense to me, if you can get a good charge at 97% or so, why go through all the hassle for 100% when you are still going to lose all of that battery relatively quickly when compared to the 97%? bump charging takes too long anyways >.<
[EVO 4G Android Development] scooter185:
4.2 smartass agressive gives me great life when off, but actually using it i can watch the battery drop kinda fast.
[EVO 4G Android Development] PlankLongBeard:
Just jumped on BFS 4.2... Anyone have reviews to share?

Thanks!

Sent From The Moon... :)
[EVO 4G Android Development] sling:
4.2-cfs-bfq-havs-more-smartass is providing me incredible battery life.

I took off charger at 94% 8 hours ago now sitting pretty at 74% moderate use
[EVO 4G Android Development] godfirst:
You are correct.
[EVO 4G Android Development] juancaperez2000:
thank ill try it
[EVO 4G Android Development] eniamg02:
Let us kno your opinion on both cfs 4.2 and bfs 4.2 please, I've been on cfs.thanks
[EVO 4G Android Development] achllles:
darn it. you twisted my arm. I was liking the cfs and gonna give bfs a try after reading what you said x).
[EVO 4G Android Development] ___DJK___:
Thanks for the comments, I think I tend to agree with you. I switched to 4.2-cfs-bfq-havs-less-smartass-universal and I'm no longer having any issues streaming pandora with the screen off.
[EVO 4G Android Development] ms79723:
After reading what someone said earlier, Im gonna try a day with the scaling on conservative instead of smartass on 4.2 just to see where i stand.
[EVO 4G Android Development] dthomas03:
Very interested in the results you get....Plz let us know. I just flashed over to 4.2 CFS/SmartASS/Aggressive UV - and its been great. I did use SetCPU for screen off profile - and my battery has not moved since last night (yaaay!!!) But I do see a pretty large amount of drain during use.
[EVO 4G Android Development] ms79723:
I'm at 40% with 3 hours of use and 4g on the whole time because school WiFi isn't working for me. This is good usage because that's 3 constant hours, no sleeping at all. Battery drain while the screen is on isn't that bad because of the scaling, its like the 4.1.9 kernel. You'll have to use screen off profile though so the battery doesn't drain while screen off, I did that last night and lost 2% over 8 hours. This is good stuff.
[EVO 4G Android Development] dthomas03:
Awesome....have you tried to use the Less Aggressive UV - if so how do the results compare with Aggressive ( on SmartASS governor)
[EVO 4G Android Development] beerad29:
Update for my phone with 4.2 BFS no havs universal

Net - I have now tried all three 4.2 BFS SA kernels. The no havs version has worked ok with my phone but BFS kernels don't do as well with my phone. I am going back to the 4.2 CFS no havs SA for now as I seemed to get really good battery life asleep and above average battery while the phone is in use.

Look forward to the 5.0 series stable versions.
[EVO 4G Android Development] R32_Rocky:
I am using 4.2 CFS SA no-havs, and have SetCPU installed, but not using any SetCPU profiles and its not checked off to run at startup, just using it to keep tabs on the CPU. So far seems pretty good on Calk's new 1.5 Rom based off 2.30 base.

But I wonder if this is to be expected - when I wake it from sleep, the screen stays blank for awhile, then the lock screen shows up. When I unlock, the system is quite jerky for a short time, then eventually becomes normally responsive. Is this the correct behavior, seeing as it was mentioned that SA drops down to 128 when the phone sleeps?

And if so, Net, did you make any new changes to the 4.2 kernels to only drop down to the normal 245 where I might need to re-download the files again?

Also, many thanks for your great work! Someday, when I get a job again (been out of work since last December, ugh!), will donate to make up for it :'(
[EVO 4G Android Development] Biofall:
So I've been testing what's in my signature, and I'm sad to say that this kernel keeps randomly hiking up my "device" usage according to system panel. When it sleeps correctly, it's a rock, but I had rapid battery loss today while it was in my pocket. Weird.

Probably back to stock for awhile to see if this problem persists, then back to net
[EVO 4G Android Development] cLOUDFAn:
using 4.2 cfs more smartass with fresh 3.4 and setcpu

battery life is great when sleep/screen off

less than 0.5% per hour

not so much when wake up/in use

overall a little better than stock fresh 3.4 kernel (since I am a light user)

big thx to netarchy for great work
[EVO 4G Android Development] THunDA:
For you people running a screen off profile, are you leaving the governor for the screen off on smartass?

edit..

Nevermind, I just read this in this thread.. so it doesnt seem like screen off profiles are needed..
[EVO 4G Android Development] PlankLongBeard:
Read The Sent From... :)

This thing is a baby evo.. with a bigger ego lol...

Awesome.
[EVO 4G Android Development] eniamg02:
Sweet! How you liking it compared to evo?
[EVO 4G Android Development] PlankLongBeard:
Honestly, its really cool! I have had my share of androids as many here can vouche but this is unique. I will be one to admit t-mobile watches these threads, many little things have been put in place. Like the reboot options. The skins look like something geniusdog / manup came up with ;)

Otherwise I have much more digging into the OS as there is many little things I didn't see in the great port from kerri :)
[EVO 4G Android Development] eniamg02:
Cool I like that phone I might have to convince someone close to get one..you'll be missing nets kernels soon :)

Haha baby evo with a bigger ego
[EVO 4G Android Development] PlankLongBeard:
Oh no my friend evo still here. You dont let go that easy. :)

That's why they have trial days...

Bigger ego cause this thing for being stock can really do some backflips! :)

BTW.... Netarchys 4.2 BFS more aggressive has given me the most battery life with all the radios on than any other kernel I've ever used. Cfs was good on live performance but BFS sleeps like a passed college student. ;)

@Netarchy If you can integrate the live governor and voltage usage for when the device is in use like you said a few pages back, I say dear dev, you will now have the Arc Of the Covenant of kernels. :)
[EVO 4G Android Development] ms79723:
Heck yeah, he's just so close to making the perfect kernel.
[EVO 4G Android Development] gotshores:
4.2 cfs was giving me great life when sleeping but wouldn't sip as well as 4.1.9.1 when being used. I'm back on 4.1.9.1 for now and its sipping again. thanks for great kernels net!
[EVO 4G Android Development] ms79723:
I'm on 4.1.9 too. Try this: turn off the feature that always leaves 3g on in your settings. And turn off roaming. I did that, and this battery is going even farther. I may get even more if I turn off GPS.
[EVO 4G Android Development] Biofall:
Ok I need some help, any suggestions welcome. My phone is showing in System Panel that "device" usage is really high when my phone is idling, and consequently it is dying all rapidly..

I just reflashed my ROM after wiping dalvik-cache and cache, and I really wanna avoid completely wiping. This problem surfaced earlier today while my phone was in my pocket.

Any suggestions would be appreciated.
[EVO 4G Android Development] wmdunn:
I would try flashing a kernel that we know is totally stable and see how it runs ... Net's 4.1.9.1. Good luck.
[EVO 4G Android Development] Biofall:
I flashed back to stock HTC (unreleased OTA from Flipz) and it persisted for awhile, but kind of went away.
[EVO 4G Android Development] ms79723:
Wel if you were on 4.1.9.1, i hope you know it kinda has a sleeping problem. But odd enough, the sleeping problem only existed when I was on Ava's rom. Im on the new OTA rooted and the sleeping problem has gone away, but I still had to use the setCPU profile and put it to sleep at 245. Did you use a profile? Because if you set it at 245, it doesnt matter if everything is running, battery consumption should still be low.
[EVO 4G Android Development] Biofall:
Yes I did know, lol I consider myself the authority on killing sleeping problems.

I do always have a screen off profile set, and it doesn't matter.
[EVO 4G Android Development] wmdunn:
I've never had a sleeping problem with 4.1.9 on any of the roms I use. It's a real favorite of mine ... great battery life. Also, I don't use SetCPU with it, just run it stock.
[EVO 4G Android Development] ms79723:
Well I know you know your stuff, you'll figure it out soon. Wish I could help, but if its an app problem, chances are that I'll be of little assistance. I dont use apps from the market, im all stock apps.

And to the post above this, yeah, i dont have any sleeping problems on this stock OTA rom. problem mustve been with Ava's rom.
[EVO 4G Android Development] Biofall:
It's not really that the phone's not sleeping, it's something like the screen eating power. The cpu is dying down like it's supposed to..

I did find that when I went in and checked some settings after reflashing, the screen settings were on a set brightness (not auto-dim) and it was set to never time out..
[EVO 4G Android Development] ms79723:
Wait, are we talking about the same thing?

Are we still talking about when the phone's screen is off? Or are you talking about when it's on?
[EVO 4G Android Development] xHausx:
I'm starting to see the tearing as well. It's not very noticable but once you know where it is you can definitely tell its there.

When the phone is in landscape and the sprint logo on top the tearing is about half an inch from the left side.

002 nova with stock rom and 4.2 bfs aggressive
[EVO 4G Android Development] ms79723:
I noticed some tearing as well...thought it was just my imagination.

I was on stock with 4.2 more aggressive cfs when it was happening.
[EVO 4G Android Development] eniamg02:
Where are you guys noticing this "tear".im on calkulin rom and haven't noticed anything.

Must be stock ota?
[EVO 4G Android Development] xHausx:
it's easier to see if you are scrolling through something like a bunch of videos in the youtube app or with the xda app. Scroll it fairly quickly but not very far and it will start to show more, it looks like the screen buffer is not being allowed to fully update.
[EVO 4G Android Development] vincey2kr1:
Think I'm going back 4.1.9.1 as well it seems to be a bit smoother and easier on the battery probably because of the conservative mode when the screen is on but 4.2 has excellent sleep battery drainage, less then 1% an hr on myns rsl3. Hum Net plz make us a 4.1.9.1 with the screen sleep state of 4.2! I think this would be the perfect kernel because 4.1.9.1 is already blazing fast, Especially in linpack (consistent 39 to 40's), I can't get any other kernel to match it.
[EVO 4G Android Development] -viperboy-:
Sent you a PM, netarchy :)
[EVO 4G Android Development] sling:
I had some major screen tear on sense widgets and App screen scrolling yesterday running 4.2 cfs-More aggressive.

When scrolling through apps on application screen it would freeze then go into psycho movement up & down 1/4 inch unresponsive to touch.

I had battery pull to get it to stop so no major harm done....Well of the exception of having to dump kernel 4.2 shortly after. I will miss that AMAZING!!!!! Battery life :(
[EVO 4G Android Development] DarkManX4lf:
Anyone have an issue with frame rates after installing 4.2? I am using fresh Rom 3.4 and by default it has fps unlocked, after I installed netarchy 4.2 kernel my fps went back to 30fps.... the only way I can fix it is by going back to fresh kernel or using novafreq anew change the frequency to 400....
[EVO 4G Android Development] sling:
I didn't have fps decrease running 4.2 on Fresh 3.3 all was swell on that front
[EVO 4G Android Development] dthomas03:
Ahhhh SenSeLess! ViRusRom
[EVO 4G Android Development] :
Im getting 52 fps, stdev: 2.71
[EVO 4G Android Development] freeza:
What makes for a low stdev? I'm always getting in the 10s.
[EVO 4G Android Development] DarkManX4lf:
Not sure what's wrong with my phone then.... I have a nova screen does that make a difference with this kernel?
[EVO 4G Android Development] dthomas03:
Might be a dumb ? But are you overclocking? Does your FPS matter depending on what the SetCPU is set too?
[EVO 4G Android Development] :
I am overclocking to 1036 Mhz, 245 for the low. I dont think fps matters with overclocking with Setcpu but i could be wrong.
[EVO 4G Android Development] :
Im not sure. Sorry.
[EVO 4G Android Development] sag7392:
@ Net

Great job on the 4.2 Beta CFS SA kernel. I used it for a few days and man, when my EVO sleeps...it sleeps! I mean it barely uses any battery...amazing. The only thing I noticed was that when in use, the battery seems to drain a bit faster than on 4.1.9.1

CFS universal aggressive...which I went back to for now. Like mentioned in a post, I believe you are very, very close to making the perfect kernel. Looking forward to that brotha!

Using EViO v1.5

OC'd @ 1113
[EVO 4G Android Development] ms79723:
You can get the same screen time usage with 4.2 by just changing the scaling to Conservative (and playing with the advanced settings) then add the screen off profile. By doing that, 4.2's screen on battery life becomes the same as 4.1.9 and it's screen off stays the same as the smartass governor.
[EVO 4G Android Development] sag7392:
Well back to 4.2 for another run. Thanks for the heads up!

Sent using the best of the best...the HTC EVO 4G!
[EVO 4G Android Development] ms79723:
Here is my advanced settings on conservative:

Sampling rate:50000

Up threshold: 95

Down threshold: 45

Ignore nice: 0

Freq Step:15

Thats's pretty much how it is on 4.1.9, but my settings for scaling the cpu down are a bit more aggressive.

20mins and I've only lost 0%...and I've been on my browser the whole time. Netarchy! How are you doing this?!?!?!

Oh, I'm also not charging my phone to 100% anymore. Every time I charge up to 100% I see that crazy battery drain when I barely do anything, when I do my small charges, I have to make my phone do real work just to lose 1%. I'm loving my Evo right now.
[EVO 4G Android Development] xNotta:
I just flashed "netarchy-toastmod-4.2-bfs-bfq-havs-more-smartass-universal".

As soon as It booted to my lock screen I got a bunch of vertical black lines.

Looked like the icons were causing them but they were even on blank home screens.

I was terrified that my display was going to blow up or something extreme so I nand restored back to my stock kernel.

Anyone else getting the black vertical lines?

If needed, I will reflash and get screen caps.

Phone info in signature.
[EVO 4G Android Development] ms79723:
Sounds like some texture tearing...try less aggressive smartass kernel. If that doesnt work, try the cfs less agressive. Like he stated in the first post, some cpu's just cant handle the aggressive undervolting.
[EVO 4G Android Development] wmdunn:
Those are the graphical glitches referred to earlier. When I had that happen, I flashed the "less" aggressive kernel and they went away.
[EVO 4G Android Development] xNotta:
Thanks that fixed it completely. :D
