Re: [Kernel-.33.4] Undervolted @ Stock-5/14 - 925mV

No clue, I'm just a beginner with all this.

There should be a warning though on ROM manager that doing this may mess up wifi, and instructions on how to enable it if problems!

Thank goodness there was a copy of my previous kernal on my SD card!
[Nexus One Android Development] mikroN1:
Same problem for me. Excessive battery drain while idle. I had a 4% battery drain in 40 minutes and never touched the phone.
[Nexus One Android Development] mooselander:
Wifi wasn't working here either, I had to revert...
[Nexus One Android Development] persiansown:
This kernel has the 21MB ram hack. Wifi is working fine over here, but I might have screwed up when I made the zip. I'll check it out later.
[Nexus One Android Development] dogiedogie:
Could you sum up the results of the blind study as simply as possible, been looking forward to the results for ages :)
[Nexus One Android Development] Cal-El:
Would really like to try this kernel without having to change my recovery. Any chance of an update.zip being posted here. :)
[Nexus One Android Development] THATTON:
+1!!! I am very curious what you found out as well...
[Nexus One Android Development] persiansown:
There was on posted.

I posted simple findings in the other thread. Basically, 925mV> 1000mV > 850mV
[Nexus One Android Development] hah2110:
Shame - I STILL get better battery life with your 850... I think my results are

Your 850 > Ravens 800 > Any 925

BUT it goes back and forth depending on usage between which is better for me the, the 850 or 800.

Re: [Kernel-.33.4] Undervolted @ Stock

I got this from ROM manager, not your zip & I still got wifi problem...
[Nexus One Android Development] hah2110:
His zip is what comes from ROM Manager.
[Nexus One Android Development] cedricj:
Confirmed WIFI not working

I can confirm that i have the same problem as well...

WIFI is ON, my Access point i seen properly but cannot connect...

The phone sounds faster to me... not sure why...
[Nexus One Android Development] Part Four:
WiFi is working fine, but battery life is definitely WORSE with this 925 over your previous 925. No question.

Also noticing an overall slowness to this kernel. Shame.
[Nexus One Android Development] bigmase521:
+1

Wifi fine here as well except it doesn't stay on when sleeping, even though I have it set to "never". Sometimes it does, sometimes it doesn't and goes back to 3G.. When I look at Wifi settings it complains about connection unsuccessful with my router, but this has always happened for me no matter which rom/kernel so I think it's my router.

Batter life is DEFINITELY not as good for me with this kernel as it was with the last 925. That was the best kernel I've used yet in terms of battery, the idle consumption was outstanding. What changed with the 33.4 925?

Not experiencing the "slowness" so much as the others though, still feels as fast as the last kernel.
[Nexus One Android Development] persiansown:
The voltage values are exactly the same as the other ones. The only thing that is different is that its a .33.4 kernel instead of a .33.3
[Nexus One Android Development] jp2000:
Does the idle voltage show something like -5 mA in OS Monitor?

I remember it used to be like this in the original kernels.
[Nexus One Android Development] nehctuk:
get back

how do i get back to the orig one like stock?
[Nexus One Android Development] bigmase521:
Well you can push the boot.img file from the Cyanogen rom, or simply re-flash the rom.
[Nexus One Android Development] Mantisen:
I'm experiencing Wifi-Problems, or to be more specific I can't connect to my WPA2-PSK protected Wifi but I had no trouble connecting to an unprotected network.

LogCat:

05-15 10:28:55.510: VERBOSE/WifiMonitor(113): Event [Trying to associate with 00:23:69:a3:b6:06 (SSID='morrvin' freq=2417 MHz)]
05-15 10:28:55.510: VERBOSE/WifiMonitor(113): Event [CTRL-EVENT-STATE-CHANGE id=-1 state=3]
05-15 10:28:55.510: VERBOSE/WifiMonitor(113): Event [Association request to the driver failed]
05-15 10:28:55.510: VERBOSE/WifiStateTracker(113): Changing supplicant state: SCANNING ==> ASSOCIATING

So I would take a wild swing at this being a driver mismatch (these four lines kept repeating over and over in the logcat when When wifi was turned on).

Other than that my battery life is awesome and I'm not getting any slowness, flashed the kernel with ~55% battery left and 22 hours later I still have ~15% battery left (or well I just now plugged it into the computer to get a logcat :P)

Great work, keep it up! (And congratulations to your 4.0)
[Nexus One Android Development] evidenc3:
Having issues with wifi also, cleared my cache and just reflashed with no affect. Guess I'll try again after the update.

I am also seeing very poor battery life. Phone was unplugged for 5 hours after getting a full charge with minimal use, maybe 10m of talk time, 5 texts and its already down to 60%
[Nexus One Android Development] perdid0:
i was having the same wifi issue. my phone was connecting to open wifi without a problem but anything with security was a no go. i flashed the newest cyanogen 5.0.7 test2 and then reflashed the kernel and everything works perfect now. hope this helps:D
[Nexus One Android Development] Mantisen:
Nice to know there is a workaround but I would love for it to work on 5.0.6 as well since that's what I'm using at the moment :) I'll wait and see what Kmobs can do, if he can't do anything about it I'll update to 5.0.7-t2 just because I love his kernels so much! :P
[Nexus One Android Development] jblazea50:
can't get wifi to work; tried flashing the rom again, as well as using adb/fastboot to push the modules and zimage; it always show up as disconnected even though the network is available

hopefully there's a fix soon
[Nexus One Android Development] AnThNeE:
same problem with me, it's really annoying.
[Nexus One Android Development] persiansown:
Flash the latest CM test and your wifi issues will go away :)
[Nexus One Android Development] jblazea50:
any chance of getting wifi to work on Enom's latest rom?

btw, i was having the wifi issues on CM test2 as well as his nightly build
[Nexus One Android Development] themetatron:
with this new kernel the battery life was much worse with enom181, and ridiculously bad with enom191/2. i reverted back to just fastboot the zImage from testgroupb.zip, and my wifi is back to normal as well as my battery life. i think 33.4 is not quite ready for showtime, or not compatible with enom's work as kmobs did say to use cyan's latest for best results
[Nexus One Android Development] Kodoman:
If you are experiencing any "lag" with this kernel, and are using SetCPU, don't use the active widget for it.

The normal one works just fine with no lag.

[Nexus One Android Development] persiansown:
I normally update my stuff via twitter.. but I figured I'd release the kernel here as well this time.
[Nexus One Android Development] Saphroxx:
I'm running your kernel right now :) Curious about the batterylife.

Thx
[Nexus One Android Development] commodoor:
I saw the picture on twitter and was curious about the battery life. gonna try it now ;)
[Nexus One Android Development] rori~:
:) and please share your results.
[Nexus One Android Development] relax24:
This still works on the stock rooted n1 rom right?
[Nexus One Android Development] hah2110:
Getting <1% drain/hour on FroYo overnight in standby with NO JUICEDEFENDER WOOHOO!
[Nexus One Android Development] Markdental:
Amazing battery life! How did you do it?
[Nexus One Android Development] THATTON:
Well, if you say it has good battery life, then it MUST HAVE GOOD BATTERY LIFE! Downloading now! How is the performance everyone?
[Nexus One Android Development] THATTON:
So I downloaded and flashed this kernel from kmobs last night because I saw hah2110 comment on excellent battery life and I know how meticulous he is about battery life. Let me tell you, I didn't expect too much of a difference in battery and if I did, I was expecting a drop in performance and response time, etc. I've been rockin' this kernel since I took it off the charger at 8am this morning(6 hours ago) and I have been using the phone quite a bit today! I am still at 92% with moderate to heavy usage(3 10 minute phone calls, 3 market updates, 35 text messages, 10 emails, checked twitter 3 times and facebook once) and the speed of the kernel is very nice as well! Excellent job Kmobs and I think I will be keeping this one for a while!
[Nexus One Android Development] hjlow:
amazing

yes amazing battery life here as well, never had any better. thanks for this.
[Nexus One Android Development] rori~:
Just flashed it....let´s see :)
[Nexus One Android Development] hah2110:
Glad to see my annoying tendencies are paying off. This is the FIRST kernel where I have MAINTAINED consistently good battery life. I.e., I have used a IR kernel where lets say the first 40% may have been a little better than this but then it drops. Same with any OC/UV kernels. I am keeping this one for a while. I want to try it on the new Rod V2.6 but am scared.
[Nexus One Android Development] THATTON:
LOL! Thanks for making the comment. Anyone else could have made that comment and I wouldn't have even given it a second look. ;)
[Nexus One Android Development] chowlala:
Rofl. Wrong thread. =P
[Nexus One Android Development] Markdental:
So did you push a different wifi from the one that is in the update.zip? If so, can you tell me which one?
[Nexus One Android Development] notxel21:
Does this kernel play well with Froyo (FRF72) I really want to try this. :)

Thanks! :cool:

[Nexus One Android Development] Markdental:
Plays perfectly with Froyo
[Nexus One Android Development] phocusrs:
I encounter one issue with goggle I've got a FC on FRF72.

I come back to IR kernel... I don't know if someone have the same as me...
[Nexus One Android Development] THATTON:
No FC's here on FRF72. Are you sure that it's kernel related? I have been VERY happy with this latest one from kmobs!!!!
[Nexus One Android Development] phocusrs:
Yes tried three time... The rom is from Asim_ag v18 and kmobs kernel was 619uv @ stock speed with kmobs #6 as info.
[Nexus One Android Development] THATTON:
Well Froyo AOSP just dropped and Cyanogen posted on Twitter that he will have a CM6.0 for us tonight so I am pretty sure that you won't be using Asim_ag v18 ROM for much longer. Hang in there! Today is going to be a good day for the N1 and Android!!!!!
[Nexus One Android Development] rori~:
I like the last kernel very much, running a day, no issues at all, battery is fine..
[Nexus One Android Development] phocusrs:
Nice to know I'll try as soon as cyanogen release the v6. Thank you for the info.
[Nexus One Android Development] notxel21:
Cyan didn't post anything about dropping CM6 tonight.

It was a joke tweet from Westgarner: http://twitter.com/wesgarner/status/16866792149

Check Cyan's timeline and you will so no such tweet! :D
[Nexus One Android Development] notxel21:
Now I'm wondering if this kernel will play nice with Froyo FRF83?

Thanks! :cool:
[Nexus One Android Development] Markdental:
Well, I installed it onto 83 and it has been fine so far
[Nexus One Android Development] Nick_Hrh:
Working fine here also
[Nexus One Android Development] hah2110:
On rodriguez 2.1 I had great battery but for some reason this kernel is terrible on 2.8.
[Nexus One Android Development] THATTON:
The battery life on all of Rodriguez' ROMs I've tried is horrible. Try kang-o-rama, much better battery life! It's not the kernel thats the problem though.
[Nexus One Android Development] hah2110:
Well it WAS great on 2.1... That is the problem!
[Nexus One Android Development] THATTON:
Yeah, that part sucks then. I guess maybe you have to trade off the speed and performance enhancements for battery consumption...
[Nexus One Android Development] Markdental:
I just have to say that my battery life has never been better on any other kernel.

I would say ~1% standby loss.

This is amazing!
[Nexus One Android Development] boesky:
Your comment has convinced me to jump on the custom-kernel-bandwagon :D

I'm gonna test my standby loss throughout the night and report back tomorrow.

Just curious.. Did you leave data enabled (3G)? WCDMA "only"/"preferred"?
[Nexus One Android Development] Markdental:
Nope, no HACK needed. Just WCDMA preferred. I actually had less than 1% drain at standby NOT using SetCPU or any task killer.

At 9 hours standby (no Use), I was at 92%. GPS and BT off.
[Nexus One Android Development] boesky:
Nice!

Anyway, does anyone have a clue if there is a significant difference in battery life on persiansown kernel and wildmonks'? (http://xdaforums.com/showthread.php?t=693375)
[Nexus One Android Development] THATTON:
That is going to depend on the user, apps, widgets, etc. Try out both of them and see which one works best for you...
[Nexus One Android Development] hah2110:
Yes... take it from me LOL. The kernel that I say is a godsend may be terrible for you. I get terrible battery life when my phone is in my pocket, on a table it is great.
[Nexus One Android Development] boesky:
Alright thanks guys!
[Nexus One Android Development] rodigezstyle:
Hey Kmobs :) i have to say.. very good work.. i would Love to see a OC Kernel from you... most of my Rom users a pretty Happy with your EnergySaver Kernel.. maybe you can do something for us Overclockers...

other question... your kernel include AUDIO/BTN/NEON changes ???

@THATTON

my Rom is sure not the Problem... Adjust your Autokiller right and you will see better BatteryLife results...
[Nexus One Android Development] boesky:
With 3G turned off, I prolly had about 2% hourly drain throughout the night .. sigh :-(
[Nexus One Android Development] boesky:
MCR r20 btw.
[Nexus One Android Development] persiansown:
erm pershoot and my kernels are pretty similar. If you want an OC one, I recommend using his. I have the audio and neon changes and of course I have the button changes (I'm the one who came up with the button fix ;))

Check your apps that are using data/keep the phone awake.

So I don't follow... What is the difference between the standard UV 950 and all of the other ones linked that are oc/uv/xtra/neon/etc etc...
[Nexus One Android Development] rjhay22:
Pershoot kernels are all oc uv / aud / neon. You just have the option to get xtra or regular.

-XTRA contains:

*some more cgroup options

*namespaces support

*deadline i/o scheduler

*v4 block device and data integrity support

*3d register driver *erratas 430972, 458693 and 460075 applied

What setting works best. Ondemand or userspace?
[Nexus One Android Development] jlevy73:
I prefer Ondemand but that's just my two cents.
[Nexus One Android Development] Markdental:

Proper Procedures for Wifi

1.Download the first version of the undervolt

2.Use Astro or SUFBS to extract bcm4329.ko

3.Use SUFBS or Terminal to mount system as rw

4.Copy .ko file to /system/lib/modules

5.reboot

6.enjoy wifi.

I flashed the second release (didnt do the first one)

Phone is running fine,

I have been running it for a few hours

and checked my battery temp its 20.2c

I have two work mates in my office who have nexus's I checked the temps of there batterys (idle phones) one was 30.4c and the other 32.5c so thats 10 degress (celcius) off the battery temp.

Further testing

neocore running (wifi enabled) for 15 minutes and battery temp is 21.3c

Very impressed thanks for the work mate!
[Nexus One Android Development] scepterr:
Works beautifully, battery drain seems to have slowed down noticeably.
[Nexus One Android Development] Prod1702:
so after doing this all seems ok but what i dont understand is under Android OS Monitor 1.0.8 under the messages tab. i am getting a msg that says [ERROR] acpuclock: unable to drop ACPU VDD. I didn't have this until i flashed the kernal about 10mins ago. Right now the phone is charging at 21.2c. How do you know if the cpu voltage has changed to what it should be now. Is there a program that will tell you what your current voltage is at? By the way after flashing the zimg and the KO file i got all OKs. So i am pretty sure all the flashes went ok.

Edit: wanted to add under settings for the kernel version it says 2.6.29.6-cyanogenmod-1225kmobs@ubuntu #6. Is this what it should say?
[Nexus One Android Development] r0adki111:
Check your kernel version under About Phone in settings. it should have kmobs@ubuntu in it.
[Nexus One Android Development] persiansown:
Oh wow thats a nice app, exactly what I was looking for. It has flashed correctly, but like I said, it won't work for everyone. It may be too undervolted for your processor.
[Nexus One Android Development] yingwai:
same here!
[Nexus One Android Development] Prod1702:
The phone is running great. Nice and fast no slow downs and i am charging it right now with the temp dropped down to 20.2c so far. Any way to check to see if it is working, or do i just have to wait and see if the battery holds up better now?
[Nexus One Android Development] mutaforce:
I also flashed second one. Phone is working ok, wifi is working ok. Battery Temp is 22.4c while charging.
[Nexus One Android Development] spyz88:
Yes that's correct. the previous one I used that was posted was #2.
[Nexus One Android Development] persiansown:
If you are getting that VDD issue, that means that you should revert to the previous kernel because its not supplying enough voltage. If you have SetCPU installed, then lock the cpu speed at each clock speed one by one and tell me which speed is giving you the error. That would be most beneficial for me as it would allow me to narrow it down to what frequency being problematic. Like I said, this kernel won't be stable for everyone.
[Nexus One Android Development] Prod1702:
Just flashed the 1st kernel for the 1st time and the error is gone so yea it was the 2nd kernel that was causing the problems. voltage must of been to low. Will have to see how much more battery life this gives. Maybe i will have to get that 1600 battery just so i don't have to charge my phone every day.
