Well we all know that some ROM/Kernel/Radio( R.K.R. for the rest of this post )setups have benefits and draw backs, usually pertaining to battery life versus function. I've yet to find one that is the best on both. I know of some arrangements that are balanced, but never full blast on both. What I would like to start discussing here are different RKR arrangements that have created either a high speed environment and those RKR setups that extend the battery life significantly. Being both a traveling person and a nerdy techi enthusiast , it'd be nice to know what I should use in my phone to allow me to listen to music / movies/ simple games the longest for 8 hour flights and what I can do to really enjoy my 3D gaming without any lag for when I don't care about my battery life.
Your thoughts?

I have good luck with the following:
ROM: CM7.0.0
Kernel: SavagedZen 0.0.1 BFS
Radio: 11.19
Also, I'm OC'd to 1.152 GHz and am using viperboy's undervolt mod at -100mV.
For me, this results in great performance and very good battery life (at least for the last day or two, during which I've made it a point to stress it and see how it runs).

2) The radio: If you've never flashed a radio, be careful and read the instructions in the thread closely.
3) As far as OC'ing, CM7 has that built in under the CyanogenMod Settings menu, no need for SetCPU.

On a side note of this make sure whatever kernel you choose uses havs. A large group of people seem to be doing just fine with -50 voltage script. Radio can make a difference also. I'm currently using and have had the best luck with the 4.08 radio.
These are just my opinions, there what works for me. However not two phones are alike. In the end I'm sure you'll find your perfect setup.

So what does undervolting do? I am assuming it reduces power consumption yet at the same time you are over clocking. It seems like two factors that'd defeat eachother. However, again, it's why I started this thread is to learn more techniques than I already know.

I am fairly sure the downloads are gone saddly. Any chance you still have the downloads for the SV? And from your experience what's the difference between Tiamat and SV?

Yes, it does reduce power consumption. I'm pretty sure the reason that it works to OC is that all the undervolt script does is change the max draw of the CPU at any given frequency. So even though I'm running at a faster clock speed, the new max voltage draw at that speed may be lower than my previous max for stock clock speed.

Yeah, I kinda figured that might be the case, but I wasn't going to rule out the POS computer I use for work. As far as why I run SZ instead of Tiamat is that the one time I tried Tiamat, I could not get my SD card to mount to my computer, despite the fact that it had been mounted just five minutes prior in order to put the Tiamat zip on for installation... After that, I gave up on Tiamat and don't bother trying it anymore.
Also, I have attached the zip of SZ for your flashing pleasure.

Which undervolt level(s) did you try? Please keep in mind that like I said, most people haven't been able to get very far with -100 or -75mv, so I am a bit of a rarity in that regard.
If none of the undervolt mods work for you, I'd advise posting in the thread and seeing if viperboy has any ideas; he's been very supportive if people have issues.
Well none of the other downloads work *cries*
Are there any other "Undervolting" kernels or mods that you know of? I know Hydra is supposed to but their site doesn't work, it seems to have fallen off the map. Ideas?
Some kernels are undervolted as part of their design. invisiblek is one of them, and I know a lot of people run it. You might give that a shot.
Also, if you mean that viperboy's links are down, it might be nice to message him or post and let him know that if he does not already.

You'll most likely freeze up and crash at the highest clock speed, that's what happens to most of us. But that really depends on your hardware... You MAY be able to sustain that, but there's really no guarantees.
What I do (and I have pretty good battery life, it's 9:36 pm here and I just now dipped under 20%) is let the kernel do it's own thing and only set up a screen off profile that maxes out at 460.
But yeah, higher clock = more battery drain.
I cannot get over 1.113, reboots constantly over that. I get amazing battery life and performance with what I am running below.
Sent from HTC Incredible, Redemption 2.0.4, King's BFS #5 kernel OC to 1.113, s-off, Launcher Pro Plus
Oh I can run it sustained i have my charging profile of 1.119 and interactive. Its 11:15 and my battery just dropped under 50% (i like bragging) But i figure it i put it to conservative it probably wont ever need to really run at max will it? Im not 100% sure on how everything works just yet
The word of the King
When King released #5, he was specific in saying that if using SetCPU w/ #5, only use it to overclock, as the composition of the kernel handles battery life.
That doesn't mean you can't, obviously, but I'm just conveying what I read when it was released.

King's notes and his d/l site go into uber-geek detail on the differences - take a look. Short version (to my understanding and probably way oversimplified) is they do different things - battery preservation or speed or a blend of the two.
That said, the kernel you should use depends on the ROM and what's important to you [speed/battery/both] - certain kernels won't/don't/shouldn't work w/ certain ROMs.Take a read thru the development section, and read thru the 2 threads for King's kernels. He's got 5? (or more) kernels out in the wild. Between those two threads, you'll see where one set is for AOSP ROMs only, the other for Sense and/or vanilla, whatever.
I've made the error of bootlooping myself by putting the inappropriate kernel into a Sense ROM - fortunately I did no permanent harm - actually it was good learning. Why? Now I look for, and use, kernels specific to the type of ROM I'm using.
They aren't one-size fits all - don't make the mistake I did - read up on what's there and you'll see what I mean.
Kind regards.

Lee - best suggestion I can offer is for you to read up on the kernels available and choose the one that works with the ROM you are running, that gives you what you want.
The reading/learning will do as much for you as a super-speedy or battery-sipping kernel.
Good luck.
I've been reading but just can't find any real information
Sent from my Incredible using XDA App
The Kernels King post are defined by whether they can be used in Sense or Vanilla. His AOSP/CM are for Vanilla Roms only, and will more than likely cause bootloops if applied to a Sense Rom. The HAVS kernels are for Sense only. I change out between 2 and 5 and can't decide which is better. I also never run above 1.15 or I get constant reboots. 1.15 still reboots, but not as often.

I ran that same combo for a while and IMO the battery did what it does best: SUUUUUUUUCK%$#^& ! .......that been said it's been like that pretty much all the time, if you really use the phone that is, not complaining at all, just saying. That's why I always carry a spare one. There are way too many variables and setup preferences that might differ from one user to the next and if you overclock the thing uses even more juice. Really love the 3.3 Rom but the lack of 3G deal in my case forced me to reflash in a different direction........Good Luck !

Exactly that......no 3G, very very poor signal if any, I thought it was just me but after reviewing the ongoing 3.3 thread I found out that some people are experiencing this issue too, very small % though. In my case I was with T-Mobile for quite a while, fantastic service but poor signal-coverage at my business location so I switched to Verizon which really rocks signal-coverage-wise until now......sooooo......I really love the ROM and really hope for a feasible fix to get back to it.
it has to be a downed tower or old prl the rom/kernel dont control the phone calls so id say to check with vzw and run the appropriate updates, hope it gets fixed for ya
I'm using KK BFS #5 and the latest SkyRaider and I've got no such issues. No 3G troubles, no battery suckage, no weird stability issues...
Seems all ok for me. I'm happy with the combination. Sedio 1750 battery, BTW.
I do have SetCPU installed, interactive governor, and a profile to lower the clock speed to 612MHz when the screen is off. When awake, the phone is overclocked one notch to 1036MHz.

I've been running KK#5-BFS on SR 3.3, and my battery life (stock battery) has been pretty fantastic. Of course, that's completely relative, and I'm not a super heavy user, but with all other variables being constant, my battery life has definitely improved since going with this combo. You just have to be intelligent with your SetCPU settings, profiles, and phone settings.

Just wondering if anybody has tried this kernel yet? Found it over on AndroidMobileJunkie.com (Followed a link in somebody's sig here n XDA that said 1.28Ghz so naturally I was curious lol) Anyways, here's the link for the post over on AMJ. http://forum.androidmobilejunkie.com/threads/kernel-ziggy471-droid-incredible-22-oct.11/
yea ziggy's kernel. It's been in discussion in both of the Desire rom port threads. 1.28 is very rough on the processor though, and mostly unstable for a lot of people's phones (mine included), even ziggy admits it's a risky business, but he has proven it is possible.
I am so tempted to try this, but I'm afraid to fry my phone. My go big or go home mentality may make me give in. Wish there was someone who posted on the thread link
I ran it. No problems a 1.28 but really didn't use it long. Here's my Quadrant post in the Desire Z port thread:
http://forum.xda-developers.com/showpost.php?p=8775977&postcount=168
X
I'd imagine that clocking the processor that high wouldn't make much difference than say, 1.19GHz.
In fact, in plenty of ROMs I've tried, anything clocking over 1152mhz actually gives me a decrease in my quadrant scores. Not to say its not a stability issue - I'd assume that most Snapdragons actually clock higher than 998mhz, but then are reduced because that's baseline performance, anything less than 998mhz would get kicked.
I've never had a ROM crash, even running at 1.19GHz, but didn't notice any performance gains, plus, unless you just happen to get a chip that is capable of 1.28GHz no problem, it's probably near bottle-neck anyway.
And Quadrant has several variables way outside of clock speed that can pull 1800's, including just your flavor ROM.
Bottom Line: It's not worth frying your phone just for a barely-existent performance gain. If you happen to have a processor that is incapable of stability at 1.28GHz, you might fry out some transistors, then get stuck with something that freezes if you clock it over 700, let alone the 998 stock.
For me personally 1.28 is no improvement over 1.152. In fact, it gives me worse benchmarks.
sorry for repost
I gave this kernel a try and I actually prefer the newest HTC 2.6.32.17 charging time has significantly decreased battery life has increased and the performance is really responsive and smooth. My quadrant scores are nothing impressive pretty average but I would rather all of the above than a high quadrant.

There's always faster, the question is will they work. lol
When I'm running the newer Sense ports, HD or Z, I can only run 1.113, no matter how much or little voltage I give it. When I'm running an older one, I can go all the way up.
As for stability at 1.28G, I need to work on the voltage more, to find the sweet spot, I just did it 'cause Jugs said one of his Bravo buds had it working, so I had to try.
I'll keep playing with it if people are still interested, otherwise, I'll just keep at the lower speeds.

I didn't take it as such, and I agree with you fully. I prefer somewhere between 1.113 and 1.15. That's the reason I included the init script to set the max at 1.113, which I find very stable and fast, hell I'd say 1865 quad with ID's Z port isn't too shabby at 1.13.
I should be able to get 1.28 more stable with playing with the voltages, it's just that takes time, and I wasted too much this morning doing both AOSP INC and Evo kernels, so I'm worn out for awhile on kernels. I still need to fix the Evo for puertoblack, since it appears I left the debug port out, so no adb for it. lol

I just rooted my DInc today and I heard about a kernel that ups the battery life. Is there such a thing, and if so, can someone point me in the right direction? Thanks in advance
Most kernels try to improve battery life. Are you running a sense rom or aosp rom?
If you're talking about Savage kernel, be careful... that thing uses an SBC (super battery charging) mod that can potentially harm your device in the long run. I personally am using VirusROM 1.5.1 with its stock kernel and have seen better battery life than SBC, but that's just me.
Sent from my HTC Incredible running VirusROM 1.5.1.
http://forum.xda-developers.com/showthread.php?t=848453
With this kernel my battery quite literally does not go down when it's sleeping (screen off), unless I'm in an area with bad reception. Screen on is also somewhat better than stock - it's hard to improve screen on at all, since that uses the CPU pretty aggressively. However, it does use improved scaling to always try and minimize the CPU load while keeping performance up. All that + HAVS (Hybrid Adaptive Voltage Scaling, which lowers the amount of power the CPU is drawing) = win battery life

The superior battery charging kernals will not harm your device, but instead may shorten the life of your battery over time. But at 15 dollars a battery, some believe it to a negligible side effect. Its all personal preference, really.

If you're sticking with the stock ROM then search for a Sense based kernel, then read the OP and associated reviews in the comments following to learn how to install it, current features (what works and what doesn't) and any other possible info you'd need.
If you're planning on installing a different ROM, those already have kernels baked in, so give that a shot first and then try other kernels if you feel the need.

Kernels for Battery
I use the Newest Ziggy Kernel (BFS) with SetCPU set at conservative.

This kernel also enables other options like SmartASS and Performance, but conservative is a winner for battery life.
Hi guys, i've been looking into many threads and reading a lot of posts and asking a lot of questions. however i know that their is not for sure answer to this but i would like to see what you guys believe to be your best kernel for battery and performance. i have seen people say it is Godmode (v9), Tiamat v4.1.0, Tiamat v3.3.7, and Savaged-zen v2.2.1. (ALL of these ARE with SBC-OFF). i just want to know what is you best kernel at the moment for your evo with decks or cm7.
Side Question: what is the difference between the governors: (Interactive, InteractiveX, Smartass, SmartassV2, Savaged-zen, and Lag Free)?

I've used damn near every kernel available for CM7. And by far the BEST kernel for battery life is Savaged Zen. I'm on a stock battery and it just seems to last forever. Add to that the fact that the battery lasts all day without sacrificing performance at all. Every phone is different and you may or may not see the same results. This is just what has worked for my phone. Honestly, your best bet is to get flash happy with various kernels until you find one that gives you the performance and battery life that you're looking for. By the way, I use SVZ Manager with my kernel so that I can toggle SBC on and off as I please. It's a nice apk that gives you some flexibility.

By the way, I use SVZ Manager with my kernel so that I can toggle SBC on and off as I please. It's a nice apk that gives you some flexibility.

at the moment i am using the latest svz kernel with the svz manager as well. i have been flashing many kernels and for a while i was happy when i used the godmode kernel my phone lasted me 1 day and 6 hours, however he is no longer updating his kernels =( i'm hoping to find another kernel such as that one that will give me around the same results ^_^

I liked Godmode. But it didn't seem to give me as good battery life as savaged zen has given me. Each phone is different though.

well im testing this one out at the moment and it has given me so far 17 hours and 20 mins, still at 31% battery, im just not sure if it'll do better than godmode did, at the moment im running it on the smartass kernel and i ran godmode on interactive so maybe that is the prob... however another issue is i've heard that svz is no longer updating as well... do u know if this is true? and one random thing that only a few people have told me is that they run on performance and overclock their phone and get the best battery from it, is that possible or a lie?
Edit: it lasted 20 hours and 53 mins, so since it didn't do as good as GodMode did then im gonna try the tiamat 4.1.0 now cause it has first place in the poll atm.

Its true that its not being updated anymore. It sucks but I plan to ride it out as long as the kernel functions properly with CM. Once it starts screwing up then I'll switch.
Those who say they get the best battery life by overclocking and putting their phone on performance are full of crap. Performance governor is basically the polar opposite of Powersave. Performance keeps your cpu constantly running at a high frequency. Logic states that overclocking to 1.13 ghz and perpetually running at that frequency requires more power than running at 245 mhz. The more power required the less time your battery will stay alive. Powersave gives you best battery life but gives you crap performance. Interactive, Smartass, and Ondemand give you a balance of performance and battery life. Performance gives you the best performance but crap battery life.
By the way, do you really need a phone that can stay off the charger for more than 21 hours? :-x

no i do not but! 3 days of the week im at school doing nothing for 8-10 hours so... i think if my phone can run longer than a day w/o charging then it mean i can play games on my phone while waiting and by the end of the day i'll still have battery. and does it make sense for someone to get better battery life on interactive than on smartass?

Well Smartass, as I've heard it described, is sort of like Interactive 2.0. It's basically the interactive governor but better. Unfortunately, I do not know enough of the exact specifics of the governors to tell you which SHOULD be getting better battery. I would just run each of those governors and see which one works better for you.
And I thought your phone already lasted 21 hours with a decent amount of usage. You need to test the governors/kernels in the exact situation you are going to be using the phone. Interactive, Ondemand, and Smartass would all manage the phone pretty much the same if you just leave it alone and let it sit till the battery drains. but they each manage the power allocation supplied to the cpu very differently during actual use. One ramps up the voltage quickly while one scales it up more gradually. So take your charger with you to school, in case you run into trouble, and use the phone as you believe you will be using it in the future. Then you'll have a more accurate idea of which setup works best for you.

just wondering what do you keep your cpu settings at: the governor, cpu min & max?
When I am plugged into my wall charger I keep it at 1113/245. I use Performance for benchmarking and testing since I don't need to worry about battery life and Smartass when doing everything else. For normal every day use I have it at 1036/245/Smartass, Interactive, or Ondemand. I don't really have a preference between the three governors since they all make my battery last more than long enough. So it usually comes down to whichever my clumsy finger happens to accidentally select first. If I happen to not go home and need more life then I'll drop to 729/245/Conservative or Powersave. I use conservative if I still need to be able to use the phone a bit and powersave if I want my phone to just sit there and look pretty till I get back home.

You're not bugging me man. This place exists so people can ask questions and get help.
I keep my min at 245 because I've read, in multiple places, that allowing it to go any lower is not something your cpu really appreciates. Just like there is such thing as too high with your clock speed there is also a too low. And everywhere I have seen 245 is the preferred low end. I am not 100% sure as to why but I would assume that it is because your cpu needs at least a certain amount of power to run the basic processes required to keep your phone functional. Similar to a computer. Lower the cpu too much and it just can't do what it needs to.

i see do u happen to know of a good thread that talks about this? cause i keep mine at the lowest because i read that its better for battery life, but they never said anything about it being bad

I don't remember there being a thread dedicated to this. I just remember it from posts I saw within different OC/UV threads. Do a Google search for it and see if that returns any results. Like I said, I doubt you'll find a full dedicated thread. But you may be able to find the individual posts where it's mentioned.

thank you, you have been really helpful ^_^
With Tiamat 4.1 and juicedefender I get the best battery performance and v6 supercharger I have a smooth screen with no problems or lag at all.
