[EVO 4G Android Development] lovethyEVO:
For me it was a couple of things. One was my phone boots faster on cfs. Don't know why, but I like it. Another is that when my phone loads after booting I don't have a lag. I can unlock the screen as soon as I can and start accessing my shortcuts. On bfs I had a lag on startup. Another is the overall performance and stability I get with cfs over bfs. I have tried netarchy, king, and baked and of those three netarchy and king were my more preferred ones until king 9 came out. Now I run solely on kings kernels.

For gentle alarm, try disabling it for a day when you don't need it and see if it overheats again. If it overheats with the app disabled it's possible something else is causing your phone to overheat and possibly the kernel though I would blame the kernel last for any overheating issue. If it doesn't overheat, then it's possible it is the app.

I personally only use setcpu to overclock. With kings kernels there really is no need to use profiles even for screen off. But there's nothing to stop you from doing so.

Every time you try different kernels, note the differences good or bad between the kernels and see which one works best for your daily use. You could try timing your boot up times between cfs and bfs and see if there is any difference. Then move on to how your system reacts to each version (faster here, slower there, etc.). I don't rely on quad scores or linpacks because most people have setcpu set on performance for those tests and who would really keep their evo on performance mode especially when trying to get good battery life?
[EVO 4G Android Development] R32_Rocky:
Thanks, good info, and I will be more alert now.

One thing I now looked closer into, the alarm also was set to use vibrate. That may have been the real cause, not just playing the alarm sound/music. I now disabled vibrate, and will see if that helps.
[EVO 4G Android Development] cowfodder:
1. Performance means your phone is running at max when the screen is on. Set to conservative for better results.

B. Lose the screen off profiles. They mess with havs.

4. Download spare parts if you don't already have it an monitor your battery history. Make sure nothing is running 100%

From my Evo to your eyeballs.
[EVO 4G Android Development] fmedina2:
I am having a minor issue with #10. It runs beautifully, I am loving it. I am getting great battery life from 100% - 30%, but once it hits 30% it goes to 0 in about an hour even if I am not using it. It was at 45% and I dimmed the screen to the fullest turned off the sync, set setcpu to powersave at 245, and in about an hour I was down to 15% with 0 usage. Is anyone else seeing this issue? I still get great battery life, but for some reason the bottom half drops extremely quickly. I am using MiniInfo for my battery readings, could it be that MiniInfo is being inconsistent? Is there a better app?

this Kernel F'ed up my phone, threw it into a boot loop....
[EVO 4G Android Development] robpet2:
make sure you clear your cache, and clear dalvik cache .. also if you downloaded it from the phone, try downloading it from the pc and then transferring it to the phone ... sometimes when you donwload thru the browser it can be a bad download..

havent had a problem with a kingklick rom since i donwloaded it from the phone and it did the same thing, since then been downloading from pc and had no problems
[EVO 4G Android Development] skantman69:
Thanks bud, already done all of that.... Not sure exactly what it was but i wiped and went back to Net kernel and all is well... you know some phones just have a mind of their own and mine didnt like this kernel for some reason... will try again in the future...

Had #9 from flashing the Virus Airborne ROM... battery was OK with minimal usage today. Just flashed CFS#10 for use with a similar day on Sunday. Should be interesting to see the difference.
[EVO 4G Android Development] EVOme:
I just flashed # 8.....damn i'm all over the place.
[EVO 4G Android Development] {SBR}_L3GION:
flashed cfs #10 and I gotta say im very happy with it. I was running bfs #9 then jumped to bfs#10 that gave me some issues but cfs #10 has given me good battery life and been great on the memory and speed. I cant wait to see what you have for all us with whatever you bring next.

[EVO 4G Android Development] xlGmanlx:
No offense, but only 1 +hours of awake time and only 3% display. There are plenty of roms/kernels that can get great battery life while sleeping. I have baked snack 1.7 loaded and i only lost 3% in 8 hours, but both i and and i were asleep
[EVO 4G Android Development] lovethyEVO:
I feel the same way. 2 - 3 days of battery life is pointless if you barely use the phone.

I did some screenshots of my battery life of constant use in a thread on this forum but apparently 8+ hours of constant use is not as impressive as 3 days of non-use. Go figure.
[EVO 4G Android Development] d34d85:
okkkk... its not like i said i was using the whole day running a bunch of stuff in it. go figure
[EVO 4G Android Development] xlGmanlx:
Over stated, point being it doesn't reflect nearly any usage so it doesn't really shed light to anything
[EVO 4G Android Development] Trident:
Very interesting. With a little less usage, I used a lot more battery. I was checking football scores and using the internet yesterday. Also had just two calls. Same number of calls today, but almost no other usage and I was down to 30% just before I plugged back in about 15min ago. Yesterday, over an hour later, I had over 50%. I know, with minimal usage, it isn't that much info, but it appears that #10 is using more power at idle.
[EVO 4G Android Development] hammysink:
I disagree with you and the others who say that light/sleep number reporting isnt useful.

Those of us who have come from phones that drain whether used or not (for me, Palm Pre) think that the phone actually keeping battery steady when not in use is a wonderful thing.

Also, several rom/kernel/app combinations will drain battery on the Evo quite a good amount while sleeping.

I like to think of the "little use, sleep most of the time" battery numbers as akin to hypermiling in hybrid cars. It provides a best case baseline even though the usage isn't very real world.
[EVO 4G Android Development] xlGmanlx:
In that case, my phone was on track for over 10 days of battery with about 30 hours of usage
[EVO 4G Android Development] TheDoctor1971:
With cfs#10 (calk's latest rom) I managed over 14 hours with moderate use including 2 hours of streaming pandora before I was down to 15%. I don't have setcpu installed or anything.
[EVO 4G Android Development] kingklick:
Very good to see my countless hours of work have paid off :)
[EVO 4G Android Development] Virus:
King thanks for all your hard work!!! gotta say though CFS 7 is my daily driver that thing has the BEST battery life imo I have tried them all
[EVO 4G Android Development] kingklick:
Just patched up my Dinc kernel up to 2.6.32.24 !

I will be merging these changes into my Evo kernel of course!

There was at least 15 commits updating the CFS scheduler.

And my Evo should be in my hands tomorrow! So excited
[EVO 4G Android Development] notasimpleway:

Great news! Let us know what rom you flash. ;)
[EVO 4G Android Development] Pao23:
As a long time and avid computer overclocker I have to completely disagree with this statement.

Anyone who dabbles knows that no two processors are the same, different parts of the waffer they are stamped from = different characteristics. Some need more juice to do the same things as others, it's as simple as that. On that note I drew the short straw on the Evo processor battle, anything after BFS #6 gives me random reboots or lockups. Ran CFS #10 for the past two days since I just installed Evio 2 1.3.1, runs absolutely amazing when it's on, smoothness level to the extreme, but when the screen is off for any amount of time it seems like the voltage dips to low and the processor just can't recover and I either lock up or reboot.

All I'm saying is don't assume all Evo's are about equal, because from the manufacturing stand point there is simply no way HTC can accomplish something like that.
[EVO 4G Android Development] sudhirkhanger:
My swype keyboard is not working and screen flow is little sluggish just like bfs #10. I am using cfs#10 with fresh 3.3.
[EVO 4G Android Development] kamiller42:
That sounds so strange. You have all these versions of a kernel running on EVO, and you haven't even owned one! How does one do that? I know there are emulators, but they can only take you so far.

[EVO 4G Android Development] fmedina2:
My battery started ok but now I am getting pretty bad battery life when not in use. It lasts about 8 hours with barely any use. Drops pretty quickly even when I am not using it. I even turned down my overclock back to normal and used ATK but its still pretty bad. Anybody else having this? I didnt have this issue with #8
[EVO 4G Android Development] cowfodder:
Reports are that ATK doesn't play nice with Froyo's built in memory optimization. Which kernel version are you having problems with specifically?
[EVO 4G Android Development] fmedina2:
I am running 10 CFS with the newest Fresh ROM. I only use ATK about every other hour to kill tasks I havent used or wont be using in a short while. I thought it might help with the battery life. Seems this kernel is using up a lot of battery at idle when screen is off.

You are wiping caches right

Sent from my PC36100
[EVO 4G Android Development] Pao23:
It's not a wiping problem, it's that some of us have a little more power hungry evo's.

Those complaining about it need to realize it's not a problem on King's part and just get over it already. Use BFS 6 or what ever works great on your system and be happy. If it works good it works good.
[EVO 4G Android Development] rebosxl:
I can't run any current gen kernels. All i get is bootloops! :(
[EVO 4G Android Development] rebosxl:
Just get over it? Wow..
[EVO 4G Android Development] hammysink:
Here's what you need to do before posting again about being unable to update kernels:

while you're bootlooping, run a logcat. then, post/send that logcat to the kernel author or post in a new thread so that people can help you out armed with solid information.

Pretty please? I know you guys feel like you're being ignored, but realize that you're in a minority class here. I'm sure that people will help you out if they have more information. We want this community to thrive.

As far as how to run logcat during bootloop you'll have to google it or search these forums.
[EVO 4G Android Development] stevo11811:
liquid, what rom are you running? and which root method did you use? im wondering if it makes a difference, does it ever make it past a certain point? or does it just straight bootloop

edit : you might have to do that logging stuff, ive never had to try, but hey man its worth it
[EVO 4G Android Development] rebosxl:
Alright I'm following your advice, thanks!
[EVO 4G Android Development] lovethyEVO:
Hey king, weirdest thing happened today.

I booted my phone this morning and shut off the screen and it basically slept the whole time I did...or so I thought.

It didn't kill my battery too much, I started from 100% and after 8 hours it's only at around 84 - 85ish.

But it's just weird that the system is reporting it's not sleeping (partial wake usage reports it as android being at 100%).

I haven't changed my system since I installed cfs 10 last week. In the attachments you can see the phone did actually sleep (since cell standby used most of the battery than the android system) but do you have any idea how this might have happened?
[EVO 4G Android Development] Drakhar:
I did just had something odd happen... While browsing through my gallery of wallpapers (200 or so), my phone was acting very very sluggish and when I checked in SystemPanel to see how much memory was being used (thought I might be maxed on memory), found out that my CPU was running at 100% @ 998Mhz. I thought it might be SetCPU acting up since I added some profiles today based on battery %, but when I killed the SetCPU task it did not stop the CPU from running at 100%. Had to reboot my phone to get it to reset. It stuck at the HTC Evo 4G boot screen for a good 3-4 minutes before showing the splash screen.. Everything seems to be good now that it is back up and running.

Anyone else had this problem??? Would this be a ROM or a kernel issue???

I'm running Myn's Warm TwoPointTwo and #10 CFS.
[EVO 4G Android Development] cowfodder:
I've had this happen on various kernels on froyo. Lose the profiles, they screw with havs, and mine stopped doing it once I got rid of them. Get rid of ATK if you're using it too.

I been on 7.6 is there any way that I can know which of the kings kernels would anyone recommended for the best battery life.?
[EVO 4G Android Development] ricsim78:
You have to check out as many as you can and test it for a day or two, what works best for my phone may not work best for yours.

It has been said and King has said himself NOT to use SetCPU. HAVS does exactly what you are trying to do with SetCPU. When you use both you are defeating the purpose as well as interfereing with the way HAVS works. How about this idea? Take out all of your SetCPU profiles and overclock when you are about to play a game.

Why do you feel the need to overclock (while we are at it)? You are not going to see a difference unless you run benchmarks and all you are doing is killing your battery faster and killing your phone faster. These games run smooth on old phones so they fly on the Evo. Please read the guide in my sig to answer a lot of these questions.
[EVO 4G Android Development] bigj225:
Are you running CM6???? if so these kernels will most likely not work on that as these kernels are for sense roms.
[EVO 4G Android Development] ricsim78:
bigj225 is correct, I thought you meant you ran 7 and then 6. If you are running Cyanogen, you need a kernel made for his ROMS.
[EVO 4G Android Development] Alopez_45:
Thanks for the quick reply, I'm not running cm6 exactly. It's that Superevo Rom. The Op recommended King's Kernel's. I lost 30% in the first hour.
[EVO 4G Android Development] MercuryTangent:
Mini squadron is choppy on my phone unless I'm overclocked. Same with fruit ninja. I also have to use a task killer to clear up some ram for them to run properly.

I'm asking specifically how I would deactivate the overclock once I'm through. With setcpu I can adjust the sliders back to normal range and put it back on ondemand scaling, but does this truly return the kernel back to its stock settings?

Umm, how does SetCPU interfere with HAVS when SetCPU regulates clock frequencies and HAVS is for voltages? lmao
[EVO 4G Android Development] R32_Rocky:
And I would like to know, should we even install SetCPU at all? Does having it on, at least to see the current speed of the CPU, cause problems as well? Or should I uninstall it?

If all you want to see is the cpu speed then download the widget temp+cpu. Works good for me and doesn't give me a huge battery hit.
[EVO 4G Android Development] kamiller42:
The man makes a good point. HAVS provides the power the processor needs based on CPU frequency and temperature. SetCPU is regulating the frequencies.

SetCPU AutoDetect & BFS #9

Does AutoDetect work with this kernel?

When I first started SetCPU, it told me to autodetect frequencies. It seemed to have worked. I ended up with 245/1152. Or did it? If I set the top frequency to 600 and redetect the frequencies, the top side remains 600. It doesn't matter what I setup the top frequency to. AutoDetect won't change it.

I am guessing that SetCPU AutoDetect did not actually work and 245/1152 are the default low and high frequency values.
[EVO 4G Android Development] EVOme:
Hot damn! Something to take me off the snacks!!!
[EVO 4G Android Development] godfirst:
It works for me, I have the options for everything king has included in his kernel. I also use setcpu 2.0.3. I also suggest wiping cache and dalvick cache with amon v1.8 recovery before you flash the kernel or anything else IMO. Also some phones take better to bfs then cfs and vise versa, so you have to play around between bfs and cfs and see which one your phone likes as well. My second evo I recieved in september prefers cfs, but the one I got in May took to bfs.
[EVO 4G Android Development] playya:
Yea I ran a test last night at 1130 I put my phone down and check the battery status and it was at 83pct and when I woke up and checked it at 615 it was still at 83pct. Now thats what I am talking bout... great job king

So what if we use set CPU for the profile settings only? Set em all to powersave except the overclock setting. Set that even a little low and ondemand. It is Still fast. Adjust as needed but never higher than 998400. Wouldn't that compliment havs?

It seems it would. Do havs kernels "underclock" appropriately? In other words, when I set my profile for screen off (the most important for battery life IMO) to 245/245.

Does havs minimize the CPU clock speed automatically, does the kernel do that? Or do we need set CPU profiles for that.

If we have crap running in Android's background (eg the task killing debate)is it running my clock speed up while the screen is off (assuming no set CPU profile is active and only havs is managing clock speed if it does that.....I thought it was voltage relative to clock speed)?

These are the questions that get to the heart of what the debate of havs with or without set CPU should be getting at.

Can a Dev or someone who is not speculating give a solid answer on this?
