i agree with impaler. i have had a rom that didnt have Gtalk and i had to find the apk from another rom to run it. its not available for DL in market. ive not tried this, but i dont see why you couldnt go to system/app then cut/paste talk.apk

ive done that with other .apk files why not this one. :)

the point to your question though is, will that fix battery drain. i would imagine thats not your issue. you can set your ATKiller to kill that often to see if it does anything or you could adjust your GT settings to not "automatically sign in". just a thought.
[Epic 4G Android Development] yogi2010:
I got hit hard by the '0' bug last night, and lost around 15% of my extended battery, even tho the phone was in deep sleep for at least 8 hours(like me, hehe). this is a huge difference, as I've actually gone overnight without losing even 1% on this kernel.... what the heck is '0' anyway?

this may be unrelated, but I also had 80% time without a signal, but my cell standby only took up 4% battery usage.
[Epic 4G Android Development] musclehead84:
Awesome kernel Rod. Phone is so fast.
[Epic 4G Android Development] jbadboy2007:
I uninstalled it. Phone is working fine

Spare Parts indicates heavy network usage from "0" and "1010". Clicking on them FC's Spare Parts for me. I see a lot of folks with "0", anyone see the "1010"? Know what it is?
[Epic 4G Android Development] theimpaler747:
There shouldn't be.....
[Epic 4G Android Development] vocaltreat:
Gtalk is just an app like any other... it will not force close anything and really isnt connected to any system functions on your phone.....its just an instant messenger....why its not in the market is beyond me but i have also had roms without it. I use gtalk a lot and i get normal batt life.....remove it if you like wont do a thing to your phone :D
[Epic 4G Android Development] musclehead84:
Just make sure you go into gtalk and under settings unchecked to automatically sign you in and then before you exit the app hit sign out. It shouldn't use any battery after that
[Epic 4G Android Development] Pwn3d:
I'm using

1000: 75

800: 100

400: 125

200: 125

100: 125

Almost instantly after I unlock it it will freeze up when I'm trying to text. Why is this...

I want the best battery saving UV numbers that won't freeze!

Edit: When it freezes I just hit the sleep/wake button and unlock it again.
[Epic 4G Android Development] theimpaler747:
You just answered why; the UV is way to high. Lower them all by 50.
[Epic 4G Android Development] Rivas123:
thanks everyone on the gtalk thing.
[Epic 4G Android Development] Pwn3d:
Alrighty ill see how it lasts
[Epic 4G Android Development] theimpaler747:
No problem :) Let us know if you need anything else!
[Epic 4G Android Development] Rivas123:
Always do ;)
[Epic 4G Android Development] yogi2010:
if you still want to keep some heavy UV, try lowering 1000, 800, and 400 mhz by 25 each. if you did that, you would pretty much have the setup that I've been using for a couple days, with no freezes at all. could be worth a try to see if it works for you too.
[Epic 4G Android Development] Custodian:
Well uh, enable the 600 freq. for better transitions, app speeds and stability. The highiest you can go on this step is 75 at the moment.
[Epic 4G Android Development] Kitteh298:
Looking forward to trying eco5 and this kernel again... but not now... I don't need an unusable phone.... what would I really gain from this anyhow? I'm running .4 with voodoo sound, and eb13.

There's undervolting... but what are some safe stable undervolts that I don't need a reboot every day or a phone that becomes unresponsive when I turn off the screen [could this problem be caused by interference by setcpu? I have it set to lower the cpu to 100-400 when the screen is off and 100-1000 when its on.

From My Samsung Epic Using TapaTalk.
[Epic 4G Android Development] jbadboy2007:
If you read the op you can not use setcpu with this kernel your phone will not wake. So don't blame the kernel for your neglecting to read the instructions that so clearly state what not to do.
[Epic 4G Android Development] anavias:
Best way to avoid problems is to follow the instructions in the opening post.
[Epic 4G Android Development] NeeceeBabe:
Hmmmm I dont know what is was... Only reason I'm posting because it never happen before.. But my phone died and when I tried to turn in on in went into a bootloop. I think it has to do with the new kernal and setcpu :(.... My phone never likes stuff sighs lol
[Epic 4G Android Development] Rodderik:
actually i think that is rom related not kernel related...some1 else in the viperrom thread reported that happening when we first released 4.0.4 but Team Viper will look into it.
[Epic 4G Android Development] Nunchucker:
This kernel dominates, Rodderik. I've tried it with both TrulyEpic-Rebirth and Nebula ROM, and it works very well. Haven't had it long enough to comment on battery life, but I'm hopeful for tomorrow. :)
[Epic 4G Android Development] professoroak:
Dang this is awesome! Running Nebula 1.0.7 with this kernel and the benchmark results are great!

After overclocking, Linpack averages increased from 14 to nearly 17. Quadrant averages went up from around 1810 to 2050(ish). Smartbench averages rose from 1180/2806 to 1300/3000.
[Epic 4G Android Development] HeisRisen:
Saw a considerable decrease in battery life than just stock nebula rom ... going to check it out tomorrow with just 1ghz and no setcpu.
[Epic 4G Android Development] konaman:
Oh ma gawd! Flashing this was like soldering and i7 processor in my phone. I cannot believe my eyes. This thing is crazy fast now. Thanks a lot Rodderik and the viper team once again u guys r the ish.
[Epic 4G Android Development] Cam3ron1:
Can u plz add a 1.4ghz step rod thx
[Epic 4G Android Development] AproSamurai:
Our phone caps out at 1.2 but can work at 1.3, it becomes unstable or spoofs out above 1.3. It's fast as is on 1 ghz and even better at 1.2. There is a kernel which allows 1.6 on Eclair but I believe that it is spoofed readings.
[Epic 4G Android Development] Toast95135:
Wow, great kernel :D I went from DK28 back to 2.1 for a while because I got sick of the slow and laggy 3D processing on DK28 (like in the gallery and 3D games). I ODINd back to stock to get the OTA but wanted to try this kernel and I have to say the phone feels fantastic. Everything is sooo smooth, Im running stock dk28 with the gingerbread launcher (it used to be chuggy b4 this kernel) now everything feels slick and smooth, even better then when I had BonsaiEXT4... 3D games (Dungeon Defenders) actually play smoother on Genocide then the OC'd 2.1 kernel I was running before!

If it's this good on a 2.2 leak, I can't wait to see what it's like on legit Froyo
[Epic 4G Android Development] brickwall99:
I imagine that depends on each phone's processor. Just as with overclocking desktop processors, some of them OC better than others, I'm sure these processors are the same. Probably explains why some people have problems when OCing to 1.3 or even 1.2 for that matter. I'd be willing to try a 1.4GHz overclock to see if mine would be able to handle it. Although with the luck I have with my desktop processors I doubt I got a high OCing CPU in this phone. lol
[Epic 4G Android Development] roghaj:
Dock support

FYI: This will not enable the dock audio out port.

I sure hope the OTA will.

That's strange I'm running the smoothest I ever been.

[Epic 4G Android Development] Rodderik:
i'm not going to bump it above 1.2ghz just yet...first i want to do some other optimizations like the framerate cap and possible slight video overclock plus a boat load of other stuff i want to get worked out...then i'll revisit trying to get the clock a little higher
[Epic 4G Android Development] lazyart:
Smooth at 1.2, but sucking at 1.0.
[Epic 4G Android Development] brickwall99:
Heck yeah video OC would be nice. Myself (and I'm sure some others) would be willing to try up to a 1.4GHz overclock when you get around to it.

Thanks for the great work!
[Epic 4G Android Development] snowmanwithahat:
I've had one issue so far after installing this last night. The stock music app with midNIGHT2.9.3 just dies and says "not enough memory".

This hasn't ever happened before with the stock dk28 kernel. I'm just using pandora and winamp as an alternative until I get off dk28... Should be soon
[Epic 4G Android Development] huytrang90:
After fully charge my phone does not wake up the next morning.

I'm running bonsai.
[Epic 4G Android Development] snowmanwithahat:
By memory it meant sdcard storage... I only had 1.5mb left. It's all good now though.

So confusing when things get dumbed down to the point of losing meaning...
[Epic 4G Android Development] BopChie:
Try 200Mhz for minimum tonight and see if it wakes
[Epic 4G Android Development] gTen:
I have been using:

1000: 75

800: 75

400: 100

200: 125

100: 125

and its fairly stable for me..whats prob going on is either your 400 or 800 is too low and when it awakens from sleep it goes up from sleep->1000mhz and freezes due to one of those not being enough..
[Epic 4G Android Development] Kitteh298:
yeah i think that could have helped, I thought i read through it... but not good enough... thanks.
[Epic 4G Android Development] shawn67:
Fabulous stuff. Keep it up!
[Epic 4G Android Development] konaman:
I use setcpu with this kernal and it works better for me than undervolt app
[Epic 4G Android Development] vocaltreat:
remember

Every phone is different......if your phone is not waking from sleep then i would not under-volt 100.....actually on another kernel i didn't use 100 because it was just too low for my phone and it wouldn't wake so i stuck to 200 being my lowest.

Trial and error gentleman...that's the fun with this kernel, we get to optimize it to fit our needs and the fickle needs of our phones. Rodd is working on the "0" thing so rest assured that will be taken care of soon :) Ive flashed my phone more then a slut in madi gras so i haven't really been able to sit and nail down my best settings. But when i do ill post.:p
[Epic 4G Android Development] Pwn3d:
Still getting freezes

I have:

1000: 75

800: 75

[Epic 4G Android Development] bryanfritz1:
Does anyone know if flashing the kernel over again will temporary fix the "0" problem?

sent from "The Other Woman"
[Epic 4G Android Development] Rodderik:
rebooting 'should' fix it temporarily
[Epic 4G Android Development] Rodderik:
does it freeze at stock voltages?

btw you're avatar cracks me the hell up every time you post
[Epic 4G Android Development] yogi2010:
I dunno if this applies to everyone's phone, but the most I can undervolt 1000 is -50..... any more than that and I get freezes when web browsing.
[Epic 4G Android Development] Pwn3d:
Idk what's stock? -25? Ill try and repost.

And lol :P
[Epic 4G Android Development] Rodderik:
stock is no undervolts on all freqs
[Epic 4G Android Development] Pwn3d:
K I don't get any freezes on stock or -25 but I do with all (100-1000) on -50.. I got one freeze while typing this, I hit the backspace and it deleted everything .. lol

Edit: I just watched my battery drain 5% in 3 minutes with little use >.>
[Epic 4G Android Development] squshy 7:
I guess thats my cue for my creepy comment of the day:

I love it when you talk dirty vocal.

Lol jk

PS. Shes right about the trial and error...thats the real fun of this kernel, because it becomes yours. Don't expect to just use someone else's settings. You HAVE to do it on your own. And FYI, the app stabilitytest makes life a lot easier when trying to find your undervolts
[Epic 4G Android Development] mis3:
This has been noted several times in this thread, but many of us have MUCH better results leaving out 600. My suggestion is to use 100, 200, 400, 800, and 1000. Put each -50 and 1000 at -25 and see if you get any freezes. If not, you should slowly bump 100 step by another 25, use for a few hours, see if it freezes. If not, raise another 25. Wash, rinse, repeat.... until you get a freeze, then stop and move to 200....and so on.
[Epic 4G Android Development] Rodderik:
since all phones are different....now you guys see why i havent posted a 'recommended' undervolt template to work from...it would just cause too much headache and still wouldn't work for every one

you gotta remember samsung chose the stock voltages to make sure a certain percentage of their hardware could keep up while still trying to reduce voltage for battery life...so it is entirely possible that some phones will not do more than -25 or -50 at any given frequency and unfortunately there isn't much we can do about it
[Epic 4G Android Development] tpike:
Rodd is right. I will get freezing if I uv more than 1ghz. I thought I had mine figured out, set to boot, would lock on shutdown. Best results for me are no uv and allow up to 1.3

I'm happy :-)
[Epic 4G Android Development] gTen:
As stated by others it differs by phone..as 2 things are never 100% the same..so lets say we were to give CPUs scores...

12,244 lets say is whats needed to pass Q/A at regular voltage...so its possible to get a 15,000 or a 12,245 (these scores dont actually exist, just trying to give an example)

That said try removing 600mhz step with the same -75 on all and see if that helps..also you set to cfq right?
[Epic 4G Android Development] vocaltreat:
word

i did post a while back that even my phone acts funny if i undervolt even more then 25 on some so its not unheard of lol.
[Epic 4G Android Development] vocaltreat:
hahahahahha stfu.....hahahah i actually look forward to your creepy comment of the day hahahahaha!

:p
[Epic 4G Android Development] vocaltreat:
By the way

Guys..PLEASE remember to thank those who helped you....it is really appreciated....almost all of us are full time parents and have full time jobs and if we dont have jobs we take up precious fam time to come here and try and help you guys. Rodd for one almost never sleeps and is trying constantly to figure out better ways to make things easier and more efficient for you. TPhillips and everyone else also take time out of our busy days to help you here and on chat sometimes spending hours to make sure your devices are running smooth. And this goes for every other developer on here. I know they gladly accept donations but a simple thanks really makes the difference :):)
[Epic 4G Android Development] churro7:
so without any mods theres no uv ?

since im not using vc theres no stock uv?
[Epic 4G Android Development] vocaltreat:
correct...if you want to uv you have to dl voltage control or another app that allows you to uv each step. It is better this way because...like said soooo many times before....every phone is different. We don't want to chance making a stock uv and have half of everyone's phones freeze up on them because there device couldn't handle it :):).....dl it and try it out...it wont hurt :D
[Epic 4G Android Development] vocaltreat:
Tpike.....lol....i smell grass...haha you know i love ya!!!!!:p:D

any who good example of a fickle phone that just doesn't like 1.4
[Epic 4G Android Development] Custodian:
Strange, but im getting better battery life without uv....
[Epic 4G Android Development] tpike:
yep me too. and when did UV i couldnt ever get it over -25 so i never noticed any difference. im able to get a full day from my epic. that makes me so happy compared to 4-5 hours on my moment.

why tho? are you getting better talk time vs battery use?
[Epic 4G Android Development] tpike:
I'm getting about the same no uv on synergy
[Epic 4G Android Development] feefeeboomboom:
whats the stablest uv any of u guys have gotten?

i rock -50 on 1120-200

i still find that some of the time under high load the phone will freeze.
[Epic 4G Android Development] vocaltreat:
ya i hardly ever talk on the phone lol mostly text but i use this beast heavily to tether and using apps and all sorts of isht. you dont have the 600 step enabled?....That usually makes it run a bit more stable but i would not undervolt that as it tends to have issues with it. you can also play around with other roms and see which is the best combo for you....our phones are very fickle with what they like and what they dont like
[Epic 4G Android Development] vocaltreat:
feefers i can t go over 25 on certain steps...and on others i can go as high as 75...
[Epic 4G Android Development] Kitteh298:
alrighty im happy now (i think...)

[Epic 4G Android Development] squshy 7:
you can't get any undervolting working now?
[Epic 4G Android Development] mrhocuspocus:
thanks for the reply, but im just curious.. why did you ask, if you dont even talk on your phone to compare it?

If you are interested, undervolting stability has nothing specific to do with our phones. all cpu's are made with the same old mask technology and its not perfect. Its near impossible to make Si chips with the exact same doping/connections as the one right next to it on the same Si waffer. When you buy an overclocked product like a video card theres a really good chance that chip in there came off the same waffer as a non OC'd chip. The OC'd one just happened by chance to be made better.
[Epic 4G Android Development] vocaltreat:
Well because I was curious and it is not hard to try and replicate it....I went ahead and made some calls....to my mom because she talks for ever and still didn't have a battery drain like u metioned.....also I'm just metioning what others have gone through as far as the 600 step . I try and read every post as tedious as it might seem. I'm learning new things every day. Thank u by the way for that little lesson...to me a reply is better then no reply at all.
[Epic 4G Android Development] JohnCorleone:
I was telling people since day one that I was getting better battery with SetCPU "on demand" than with Voltage Control but my phone can barely UV at all. Also, SetCPU seems more stable than the new No Frills CPU which is SetCPU and CPU Spy in one app with same governors.
[Epic 4G Android Development] Kitteh298:
Hey how are your batteries? I saw a guy with like 24 hours unplugged and only 25 percent gone... how do you even do that :o I have my undervolts set but my battery is pretty crappy. Its been unplugged 4 hours and 20 minutes and the battery is 57..

I should note though that I have 1 hour of screen on time and that 4g was on most of the time.

[Epic 4G Android Development] vocaltreat:
i dont know..lol that guy must have some kind of unicorn phone lol.....but i know that 4g drain the batt pretty fast as well as having your screen on....my screen on counts for a lot of my batt drainage. Try turning off 4g when your not using it.
[Epic 4G Android Development] Kitteh298:
Its kind of a hassle to do one thing and turn it on off on off. I usually turn it off if I have the screen off though. But our home. Internet is garbage right now... effing comcast.

Also since I got on ec05 I have the old market.. its quite annoying.. how do I make it check for updates?

[Epic 4G Android Development] Pwn3d:
Ok so I don't really get any freezes and ill mess with the freqs later.

But when I unlock my device this is what happens on a test:

Unlock

Swiping between pages

Freeze

Power/lock button

Unlock

Swiping between pages

No freeze

Whats up with this?
[Epic 4G Android Development] tpike:
When you say freeze you mean you are having to pull battery right?
[Epic 4G Android Development] Pwn3d:
Nope my screen has little or no response. So I have to hit sleep/wake and re-unlock it and it's fine.. but this gets annoying, especially when trying to text
[Epic 4G Android Development] tpike:
Id call that a lag, but that might not be right. My mess will lock up and require a battery pull. Can you post your voltage control settings? With out seeing id guess you are uv too low or having trouble with 100mhz.
[Epic 4G Android Development] Custodian:
I can uv. But not as hardcore as before. I didnt see any real gain from it either so the hell with it, may just purchase an extended battery.
[Epic 4G Android Development] Pwn3d:
My setting are:

1000: 50

800: 75

600: 75

400: 100

200: 100

100: 50

On CFQ

How can I get rid of this "lag" if that's what it is because that's what I think it is too..
[Epic 4G Android Development] vocaltreat:
Try diasableing the 100 step...don't use that at all and see if helps. Some phones trip when it dips below 200....you can also try not undervolting the 100 step too
[Epic 4G Android Development] Pwn3d:
How long do you think the battery will last without 100MHz and no UV on it?

By the way I'm using Go Launcher EX if that matters at all?
[Epic 4G Android Development] vocaltreat:
honestly i don't see any difference as far as the 100 and 200 step is concerned. It just bumps it up enough to keep the phone from going into that sleep o death some experience. I still get good batt without 100....you can keep the uv on everything else..

ya know......im not sure lol
[Epic 4G Android Development] yogi2010:
lol, that's cool. I got the app... the only thing I can't figure out is how to disable certain frequencies(or states, like in VC), but maybe this app doesn't allow that?

edit: according to the thread, it seems that a freuency can be disabled(it will turn grey), I just haven't figured out how....
