What is the deal with wiping battery stats? Are you supposed to do this when switching kernels?

Sent from my EVO using the XDA App!
[EVO 4G Android Development] lokitoorg:
I just try to flash version #9 but once i get to the lock screen i can`t unlock the phone is like is not responding to anything, am running cyanogen CM6, then i try to load netarchy but is doing the same thing lol. Not sure what to do now.
[EVO 4G Android Development] pongoface:
These kernels do not work on cm6. Use snap kernels.
[EVO 4G Android Development] lokitoorg:
Thanks, i learned the hard way i guess, i flashed fresh 3.2 and installed Kingxkernel #9 again, let see how it goes.
[EVO 4G Android Development] pongoface:
That's my daily runner u just flashed lol. Works for me enjoy.
[EVO 4G Android Development] cemzie:
just reflashed and all worked fine. I noticed with video playback from the camcorder it seems very glitchy and the video is not smooth. it doesnt seem to be effecting any other video playback. Anyone?
[EVO 4G Android Development] glaex:
anyone have a link to baked snack 1.5? i have the same prob as that metalhead guy and willing test. running evio 1.1 with bfs 6 for a while now and have no probs but bfs 8,9 circle boot, every netarchy kernal ive tried thats 4.x does too. your cfs 8 works, baked snack 1 works, snap kernals ive tried (none recently) have worked.. hardware rev 002, 3 touch point, nova panel, class 2 sd card
[EVO 4G Android Development] MSmith1:
Has anyone tried charging an extended battery with bfs 9? Im running the 3500 and just want to make sure that the battery tweak in bfs 9 works with the extended battery.
[EVO 4G Android Development] smw6180:
I have the same battery and I've been having issues with battery drain. Obviously it's not '5 hours and gone' or anything, but for this battery I should get much more than 12 hours (and usually do). I had to switch back to bfs #8. Which sucks because this is the only kernel I've been able to successfully run 1228 on.
[EVO 4G Android Development] MSmith1:
Have you charged the battery in the phone with bfs 9? I wonder if that has anything to do with it because im getting great battery life on bfs 9 with the 3500 but I charge the battery in a dedicated wall charger.
[EVO 4G Android Development] smw6180:
Yep. It's been through 4 charge cycles (2 AC, 2 USB), initial battery level drops 10-15% in the first 10 minutes (I know about the charging bug on USB) and then it seems to lose 5-10% every 30 minutes after that depending on what I'm doing. Sitting idle off the charger it's closer to 5%.
[EVO 4G Android Development] godfirst:
I see this type of decrease also with the standard battery, but once it gets to under 80% the battery never seems to drop at all I'm on a day and 56min with 28% and I've been using it moderately, to heavy use.
[EVO 4G Android Development] MSmith1:
Interesting. Im not experiencing this. I guess ill just keep charging in the external charger.
[EVO 4G Android Development] leeh41:
Flashed #9, and like everyone says, first 10-15% drop pretty quickly. Its been sitting at 80-78% for the past 3 hrs of idle.
[EVO 4G Android Development] Biofall:
I'm not having that at all, but that first initial drop doesn't really have much to do with the kernel. If you go to the battery link in my sig it provides another link to a thread with a solution that is 100% confirmed to fix the initial drop
[EVO 4G Android Development] hungry ghandi:
Bummer. Just flashed #9 BFS. Looks/ works beautiful for the first half hour - . Then I start getting reboots about every 15 minutes(I presume relating to how my individual device fairs with undervolting?). It's not doing it as often as #8, but at the moment, it looks like it's back to netarchy beta for me.
[EVO 4G Android Development] smw6180:
It probably means you're OCing too high.
[EVO 4G Android Development] Noxious Ninja:
I'm getting occasional reboots with BFS #9 (3 or 4 times over the last two days). I wasn't getting them with #8. I'm not OCing at all.

It's not annoying enough to bother flashing back, though.
[EVO 4G Android Development] Noxious Ninja:
EDIT: Bah, double post.
[EVO 4G Android Development] dplante:
With #9 bfs,I'm getting really bad battery life,can't go 10hrs without connecting it to the charger
[EVO 4G Android Development] lucidvtec:
been using evio 1.1 and BFS 6 for awhile

tried evio 1.2rc with BFS 9 boot loops....wiped everying twice us RA

flashed again evio 1.2rc with BFS6 runnin smooth
[EVO 4G Android Development] Shauli20:
I can't say for sure, but so far I do seem to be getting worse battery life with BFS #9 vs #4. Also, I don't know if it's related, but it's been about 24 hours since I flashed #9 and earlier this evening my EVO went through a major slowdown which made me need to reboot. I'll experiment for another day or two, but I'm tempted to go back to #4 which I knew and loved...
[EVO 4G Android Development] kingklick:
Funny that people say battery life is worse, this one is much more under volted

Stop using set cpu guys!
[EVO 4G Android Development] Shauli20:
What about Overclocking Widget? I'm using that, and with your BFS #4 I was getting excellent battery life. Now on BFS #9 should I uninstall OCW?
[EVO 4G Android Development] lucidvtec:
haven't used Setcpu or oc widget since BFS6 came out
[EVO 4G Android Development] TheDoctor1971:
I removed setcpu and with #9 and BakedSnack 1.7. Fairly heavy usage I still had 53% battery left after 8.5 hours. I'm not using any apps to prolong battery life. I do have a task manager but it isn't set to auto kill anything. I just like the option to kill something if I like. I even streamed music for an hour at work. I've certainly no complaints. Beats the hell out of stock. :)
[EVO 4G Android Development] dudewithnofood:
Mind sharing your exact set up? Rom and any apps you maybe using to prolong battery life
[EVO 4G Android Development] cemzie:
Anyone else having a small stuttering issue with video playback through stock player? Love this kernels battery and overall performance, the video playback seems to be the only problem im having now.
[EVO 4G Android Development] FAndroidHTC:
Running #9 and loving the battery life!
[EVO 4G Android Development] Biofall:
That's awesome, and around what I'm getting, but when I try to stream music it skips songs after a couple of seconds :P
[EVO 4G Android Development] Biofall:
Check out the link in my sig, then take away the setcpu options I mention
[EVO 4G Android Development] mrwilly:
i have bluetooth issues as well with BFS #9, it goes through the pair process, but won't connect to my Acura TL. no issues on BFS #8.
[EVO 4G Android Development] jerdog:
Installed BFS #9 when it came out on my freshly flashed AVA v7. Worked great for about 4-6 hours, great benchmarks, etc. Then all of a sudden the touchscreen became WAY under-responsive, the whole experience went slow and to set it all back I had to pull the battery and restart. About 4-5 hours later it happened again. I went back to CFS #8 and BFS #8 under the same testing and both were fine.
[EVO 4G Android Development] rsage:
I think I'm having bluetooth issues as well, though I can't be 100% sure it's this kernel (#9). It now takes me multiple attempts to connect to my bluetooth headset every time I use it. ROM is Baked Snack 1.75. I'm pretty sure this started when I flashed the new kernel (after wiping dalvik and cache of course).
[EVO 4G Android Development] mrwilly:
BFS #9 is the only time i've ever had issues with bluetooth. On BFS #8 and on netarchys beta, it would connect right after pairing up the phone with the car and that never happens with BFS #9
[EVO 4G Android Development] Noxious Ninja:
I've had this happen several times with different kernels. I've never been able to figure out the cause.
[EVO 4G Android Development] onyx00:
It's probably the iqfd process - several have seen this pegging the CPU for some unknown reason. I have yet to see an explanation for it.
[EVO 4G Android Development] Shauli20:
What's the iqfd process?
[EVO 4G Android Development] felacio:
King bought a Vibrant instead of an EVO?....

at least that is what your signature would lead us to believe. Doesn't say Desire anymore.

Hmm...
[EVO 4G Android Development] Joker022:
He's got a Vibrant AND he's getting an EVO. Don't worry, he's not forgotten use EVO folks!

Anyone using VPNC with the kernel? http://code.google.com/p/get-a-robot-vpnc/

Everytime I try to insmod /system/lib/modules/tun.ko I get a

insmod: init_module '/system/lib/modules/tun.ko' failed (File exists)

No help through the Googles.

Thanks!
[EVO 4G Android Development] fazzmanic:
He never intended to get an Evo. Just your donations.
[EVO 4G Android Development] JZR:
VPNC hasn't worked for me for a long while. I can't remember which was the last kernel that worked. You can't insmod the tun.ko, because it's already built into the kernel, but the routing is messed up. You can connect to Cisco VPNs, but are unable to go anywhere.
[EVO 4G Android Development] toddtwods:
Groan, bummer. Anyone know how to get to the route table and adjust?
[EVO 4G Android Development] JZR:
I just tried the command for cellular network in the link below, and this fixed it for me. Give it a try. I haven't tried the wifi command, but I suspect that it will work also.

I removed setcpu as you stated and wiped battery stat. Battery life is amazing. Will post usage stats at the end of the day. I'm at IDF 2010 and will be out all day. Halfway done and still at 78%.

I'm on BFS #9 and just uninstalled Set CPU. Is anyone having issues with the notification sounds lagging with handcent? The message will pop up first then the notification tone a short time after. I don't know if this is a kernel issue or not.
[EVO 4G Android Development] shortbus182:
Jebus..who gives a **** what he did with donations.. king has put a lot of time and effort into these kernals. He deserves to spend his hard earned cash however he pleases.
[EVO 4G Android Development] SITH16:
Did he stop supporting this kernel?
[EVO 4G Android Development] leeh41:
Ok. Just left the IDF2010 a bit early, so its not a full day's result, but see attached for usage and remaining battery with #9.

I saw some people had issues with bluetooth, and I can confirm that I had no problems with BT. Connected to my Blueant head set, and FIPO without issues.

Battery life seems the best of all of King's Kernels so far. I've used #1,2,3,4,5,6 8, and 9. (#8 drained very fast)

You will noticed it was plugged in briefly around 10am, because I was using the GPS and wanted to be sure i had enough juice for the remainder of the day.

Not sure what happened at 2PM, looks like a random shut off for about 15 mins? I didnt even notice until I looked at the history.

It was briefly plugged in around 3PM (like 5 mins) but then I realized I wanted a good reading of power consumption, so I quickly unplugged it.

2nd image attached is yesterday's screenshot.

I wiped davik and cache twice. wiped battery stats, then flash #9. Battery was around 10% when I wiped and flash. charged to full without unplugging.
[EVO 4G Android Development] saccityp:
Is anyone having battery issues? I'm kernel 7 because of lag experienced on #9. I also have the seidio 3500 and its eating through my battery compared to stock.
[EVO 4G Android Development] Shauli20:
Agreed. I will donate too for the hard work put into these wonderful kernels.

King, I hope you don't stop supporting us EVO users because of a few nasty remarks by some ungreatful individuals.
[EVO 4G Android Development] ReallyShawn:
Just wanted to chime in. King has produced some quality roms. I have no idea whether he is getting an EVO or a telegraph. Thanks for the memories or the futures. CHEERS King.
[EVO 4G Android Development] kingklick:
setcpu has never been a good thing for battery life with my kernels

It defeats the purpose of havs
[EVO 4G Android Development] Shauli20:
Well, today my battery life was much better (#9). I'm still using OCW, I'll try tomorrow without. Thanks King!
[EVO 4G Android Development] SITH16:
Ok, first kernel I've flashed to my evo, do I need to rename the zip or anything? I have put it on the root of my sd card and am gonna do a back up before I flash, I just need to know if I need to rename it to update.zip or anything.
[EVO 4G Android Development] Shauli20:
Nothing. Just find your file in Recovery and flash it. Reboot. You're done!
[EVO 4G Android Development] juancaperez2000:
Kernel bfs#9 is amazing 10% down with one hour streaming music
[EVO 4G Android Development] PhantomApollyon:
I've always used it but I'll uninstall and see how it goes tomorrow. Not that 2 full days of light usage is bad however betta is betta.
[EVO 4G Android Development] Philosuffer:
What about using SetCPU to force an underclock when the screen is off, wouldn't that help?
[EVO 4G Android Development] RTC88:
I don't think it is necessary since when your screen is off the cpu isn't getting taxed anyways; therefore, it will already be running at a low clock speed.
[EVO 4G Android Development] notasimpleway:
Nope. The CPU lowers itself when it sleeps(screen turns off). I get better battery without SetCPU.

[EVO 4G Android Development] wsantiagow:
I really don't care king bought a vibrant. He has given us some great kernels and he can continue to do so. He doesn't really need an EVO to produce. I too like the Samsung Captivate.

battery life with BFS #9, first report

Earlier I mentioned how snappy and fast this kernel is and reserved judgement about battery life until i test it out. Initially my battery life seemed a lot worse than on other kernels. I was going down 12~14 % an hour. Every time it hit 70% I charge it back up and do the charge/turn off/charge/repeat trick but it was not helping, 12% per hour was unavoidable. This was over the weekend using setCPU, stock rom, ADW Launcher and king BFS#9.

On Sunday night I decided to uninstall setCPU and go to work with a full charge. first 3 hours my phone was at 68% with VERY light to almost no use. I had meetings all morning so I wasnt doing any calling/browsing/streaming.. I figured its gonna die before I get home. 2 hours later my fiancee calls me and we talk for like 30 mins or so, I take a look at the battery and its still holding at 68%, cool. Go to another meeting, call buddies at work for lunch, call fiancee again for 20 mins and I take a look (about 2 hours after the last check) and it was at 67%!!

After going to the gym at night (no signal for 2 hours) I plugged it in it had 17% juice left and was at 16 hours and 51 mins since last plugged in. In the battery usage I had around 3 hours of voice calls, bluetooth was at 16 hour 51 mins (I have bt on ALL the time).

I would describe my usage to be light, as I did not play games, maybe 5 texts/emails and about 3 full hours of voice calls with bluetooth on the whole time. For once, my bluetooth headset died before my phone (:

This is only the first field report, I still want to try setCPU and maybe Fresh rom instead of stock and see if it makes a difference.
[EVO 4G Android Development] robotrabbit:
This is my first kernel and I'm loving it. I ran into a problem after install with the camera that I was able to fix so I figured I'd put up my results for future readers who may search for a solution.

I had a problem with camera detection when installing Fring. The install said I didn't have the hardware to support video calls. Although disheartened for a moment I was able to go into Fring's settings and check the box to enable video chat.
[EVO 4G Android Development] mrjeancw:
ok so i really tried reading thru most of 293 pages of post but im afraid i will loose my job due to my high net surfing lol...so i just flashed leaked ota froyo 2.2 and udpated radio and wimax to latest...everything is working fine. now i want to flash a new kernel and im on clockworks. im reading through thousands of post and i have came across the difference between cfs and bfs (bfs is faster but cfs is stable)...also, what im really looking for is fps unlock, unless someone believes one to be superior over the other. any insight would help. if both kernels have fps unlocked im guessing ill go to the stable one.
[EVO 4G Android Development] Success100:
the first page has the details on bfs vs cfs. They both have the fps unlock. It boils down to preference. the general consensus is BFS= faster, but not as good on battery life and stability as it is new "technology" (for lack of better term), and cfs, is more stable, with better battery life. Try em both out....
[EVO 4G Android Development] funcrusher:
Switched to BFS #9 from CFS #7 because I no longer wanted to use setcpu just to change the default governor (I'd get some lag with conservative and thought since he changed to ondemand on BFS #9, I'd give her a spin).

It just doesn't feel as fluid to me.

Is there a way I could change the default governor in CFS #7 to interactive or ondemand without using setcpu or any kind of app (manually)?
[EVO 4G Android Development] Shauli20:
Try Overclocking Widget. It doesn't have different governors to choose from, but from my experience it delivers solid performance with excellent battery life.
[EVO 4G Android Development] Success100:
i decided to take kings advice, and run this kernel without using setcpu AT ALL.

The phone runs so much better with out using setcpu on BFS #9. I dont care about benchmarks. Battery life is much better without it, the phone doesnt hang on anything...I recommend for any one having stability issues, try running without setcpu enabled
[EVO 4G Android Development] kingklick:
thank you!

finally someone who listens to me :)

I do not just pull stuff out of my *** to sound like I know what I'm talking about.

There's a logical reason behind SetCPU mucking this kernel up, and I've explained it countless times.

:D
[EVO 4G Android Development] SITH16:
I have been running thsi since last night, it charges all night and has been off the charger all day....From 8 am US est till now and it doesn't seem to have made a change in my battery life. I don't have setcpu on it at all.
[EVO 4G Android Development] funcrusher:
Thanks, but I'm wanting to figure out how to change whatever system setting determines the default governor, so that i can be with CFS #7 FOREVER.

I guess it's in the kernel?
[EVO 4G Android Development] Genjinaro:
I still can't figure out why BFS #9 drains the battery so fast, especially given its lower voltage. (Never used SetCPU) JuicePlotter said I barely made it 5 hours.

Is something from this, spiking the CPU maybe? I noticed my awake time is higher with it.

BFS #8 Seems to be ok, no difference in apps or setup, back to 8-hour status (above average useage).
[EVO 4G Android Development] leeoniya:
ouch. #9 is quite smooth for me under Fresh 3.2 + setCPU @ conservative. 30-32 hours w/ mostly standby, 20 hrs avg use. 12 hrs with moderate use...though i usually keep all of my radios off (including 3g mobile data) when not in use except for wifi. also pretty minimal streaming in all scenerios.
[EVO 4G Android Development] Success100:
well this advice worked great. thanks dude
[EVO 4G Android Development] rebosxl:
Still in the process of testing this theory, with the identical usage pattern I had yesterday. If it does this should last me until 10 tonight and right now that's looking impossible
[EVO 4G Android Development] leeoniya:
yeah, not sure how the new default on-demand gov in #9 can top battery life of conservative via setCPU.

btw, any way to change the gov without setCPU?
[EVO 4G Android Development] Biofall:
Have you checked under settings, about, battery, to see if your up time is equal to your awake time?
[EVO 4G Android Development] Philosuffer:
So, without SetCPU, how do we take advantage of your OC and other optional governors?
[EVO 4G Android Development] Genjinaro:
Its not equal but its very close, a few minutes difference.

Not the case on #8.
[EVO 4G Android Development] rebosxl:
Overclock widget? But yea his advice wasn't only wrong its dead wrong, same usage pattern and im almost 15 percent lower than I was yesterday when i got home and im not even at the part where I play music and chat for a hour lol! So I learned that underclocking is useful...wish I knew that before I was stuck on bus with my battery about to die and its going to be a hour before I get home the earliest. Thanks king lol :)
[EVO 4G Android Development] kingklick:
on a side note

I am NOT saying using set cpu for changing your CPU GOVERNOR TO CONSERVATIVE IS BAD

that's the only change I would make for longest battery life
[EVO 4G Android Development] tsipa:
King,

I will definitely give your advice a try. So you are saying that limiting screen off frequencies is bad as well?

BTW, #9 is amazing.
[EVO 4G Android Development] MSmith1:
I've been saying this for a while now. Get rid of your setcpu profiles. If you want to use setcpu, use the main screen only to change your governor or to set your oc and that's it. I haven't used profiles in months and I get good battery life on several kernels and I use everything my phone can do. On BFS 9, set the governor to conservative and forget it.
[EVO 4G Android Development] darkhova:
Ok I can vouch.......I been using king's kernel with set CPU and it would install fine but the phone at times would hang and I would get FC's in LauncherPro.....I installed oc widget....uninstalled setcpu and wipe both caches and install #9 and this thing has been smooth....On top of that it took my battery 2 hours to drop the first 10 percent which is usually Gone in like a half hour.....Battery Life AND Performance both increased...when switching to OC Widget....all this while overclocked to 1228mhz..
[EVO 4G Android Development] jasongthang:
I agree. Of course all phones are different, but regardless of all the different tips I've heard about how to set profiles, I've always had problems. I've been problem(lag)-free with no profiles, except for a Temp profile, and setting the max to 1.17.
[EVO 4G Android Development] bluefire808:
Im guessing for sure this has been asked and answered but by browsint i didnt find a answer from the ki g him self. Are there plans to make a kernel for the new ota 3.28.651.1 ?
[EVO 4G Android Development] willy900wonka:
I can say that HULU fix is viable in BFS9 . Though I did reinstall the 6 "hulu fix" stage fright .so's in system/lib. Also wiped Hulu's data after I switched from bfs8 to bfs9. For what it's worth.
[EVO 4G Android Development] shortbus182:
King, are there any new audio tweaks in #9? After flashing, my speakers sounds ****ty, like its blown.
[EVO 4G Android Development] Shauli20:
There is one already. Look for a thread by King in the EVO development forum for a kernel for Sense UI specifically. That one is based on the new software version, and is still in it's early development stages. Last I checked, it's still at #1.
[EVO 4G Android Development] Pao23:
With a fresh install of everything (Rom included) 9 was running poorly on my phone, jittery, unresponsive at times. Threw 6 on there and all is right with the world. I think my phones proc just needs a little more juice to run stable then some others.

No biggie though, 6 is buttery smooth, so I have no complaints, that'll probably be the end of my kernel flashing though.
[EVO 4G Android Development] EVOme:
Hmmm, never heard this before. Let me disable mine on #9 and see what happens. Currently with all the profiles enabled I am not seeing anything diff from all the other kernels I've used.

Do you suggest a cache wipe/batt stats? Also, I have my govenor on "On Demand"
