It's probably your radio constantly searching for a signal. Turn your radio off and it should stop draining.

Wait... your sim isn't in so it can't be that. Wipe battery stats and check battery for a bulge.
[G2 and Desire Z Android Development] solracarevir:
I tried this kernel, but my Wifi stopped working :( im Using the latest Radio (from Gingerbread Leak)

Do you recommend using another Radio?
[G2 and Desire Z Android Development] piruzinho:
what exactly is a bulge, sorry?
[G2 and Desire Z Android Development] jmwils3:
a bulge is a physical defect in the battery itself, which causes part of the battery to bulge outwards. Its a sign of a bad battery, in need of replacement.
[G2 and Desire Z Android Development] umaro:
By bulge, he means that the battery is no longer flat on the sides, but has a bump in the middle sticking up. It's a little hard to explain, but if you've looked at your battery before, and you look at it now, it should be fairly easy to tell if it's developed a bulge/bump. If so, it's time to get a new battery.

I have no idea why you'd be getting that kind of battery drain otherwise. Did you check your battery stats to see what it says is using it?
[G2 and Desire Z Android Development] G1ForFun:
Can you just list the apps you have installed on your phone to rule out one of the apps being the culprit?
[G2 and Desire Z Android Development] piruzinho:
hey all,

i definitely do not have a bulge, i just checked.

my drain is amazing- and again, i'm not sure if its the latest CM or its the umaro kernel, but either way i'm this close to going back to the old nightly i had, this is absurd.

i have many apps installed, should i list them all? i know that my battery statsis just k-9 mail/spare parts/launcher pro/settings (according to spare parts) and accoridng to settings "what has been using your phone" i have "cell standb (77%)/wi-fi (11%)/phone idle (11%)

so weird...
[G2 and Desire Z Android Development] G1ForFun:
Do you use a really high brightness? Do you keep all your location services on? Just curious.
[G2 and Desire Z Android Development] popimp315:
Anyway you could develop a kernal based on .32. Seems like the other devs have left them.
[G2 and Desire Z Android Development] piruzinho:
Yeah, my brightness is high, but no location services. Still, I think the important thing here is to compare the old build/kernel with the new build/kernel - no config or usage patterns have changed, ergo it must be something with the build or the kernel, no?

crazy vibrate

i've had supercm7 v1.9 for about a week, then found the umaro kernel. flashed it last night, but for some reason now, everytime there's a call, the phone vibrates like crazy, when i pick up, when i'm talking on the phone. i'm like wtf? i've checked the call preferences and the vibrate on call and hangup are unchecked. even when i check them and uncheck them again, it still does it. kind of annoying. any recommendations?
[G2 and Desire Z Android Development] siulmagic:
hey umaro, dont know if you saw it or not, i left instruction on what you need to change in order for this kernel to work on sense roms. im just curious how sense runs at 1.8-1.9ghz =).
[G2 and Desire Z Android Development] jmwils3:
you and me both, man. have you actually MADE the modifications to the kernel that you outlined in that post? Id love to get some scary goodness on my InsertCoin :)
[G2 and Desire Z Android Development] siulmagic:
not yet, i cant seem to be able to dump my boot.img, every time i try adb fails to map my partition's, so i cant dump it, but if any of you do, i can edit and post it so we can all try it.
[G2 and Desire Z Android Development] umaro:
I looked into this, but I don't actually distribute a ramdisk with my kernel. It uses koush's anykernel patch, which basically extracts the current ramdisk, and repacks the boot partition with my kernel and the old ramdisk.

So in theory, if that's all that's required, then my kernel should work fine. If not, there's gotta be something else going on preventing it from working on sense.
[G2 and Desire Z Android Development] siulmagic:
not quite, sense needs its own ramdisk, cm7 customized one will surely not work.
[G2 and Desire Z Android Development] umaro:
No, that's what I'm saying.. there isn't a ramdisk in my kernel update.zip, at all.

It extracts the ramdisk from the boot.img and repacks the boot.img with my kernel and the extracted ramdisk.
[G2 and Desire Z Android Development] jmwils3:
So, have you tried it on a sense rom?
[G2 and Desire Z Android Development] siulmagic:
oh wow dude, i totally miss read your post. doing 20 things at the same time, never ends well.
[G2 and Desire Z Android Development] umaro:
No, I haven't tried it in a sense rom yet.. I actually hate sense with a passion, but i'll load it up and see if I can figure out what's wrong with it. Maybe i'll send rmk40 a PM, he might be able to give me some pointers.
[G2 and Desire Z Android Development] Ritualz:
Anyone having problems with Cm7 Nightly 99 and this kernel?

Cant clock the CPU to more than around 1700mhz before the phone freezes like 3-10 sec after i set the CPU speed and i have to do a battery pull . It happens so far i know in both Odemand and smartass. Just tested with performance and its stable (most likely...)

And thanks for awesome kernel :)
[G2 and Desire Z Android Development] sundar2012:
Not all g2s can handle clock speed that high...but always post a logcat with bug reports like that.
[G2 and Desire Z Android Development] pmcqueen:
would you be surprised if you clocked your desktop's processor to more than twice its advertised speed on air and you started getting bsod's? not that an arm-based snapdragon is necessarily the same beast when it comes to overclocking, but you catch my drift...

you may not ever get it to run well at 1700mhz, and you shouldn't be disappointed if that's the case.

(ps: not trying to be a jerk if I came off that way, just sayin' ;))

(pps: thanks for the kernel, umaro, have been using it between the default CM and pershoot's since you released it. quality stuff!)
[G2 and Desire Z Android Development] Ritualz:
I'm not surprised at all :D But i had it going on 1900mhz on Nightly 88 a few days ago, with smartass government on . so i just had to see if anyone else got the same problem. Like i said its now running at 1900mhz just fine with performance government. :)

Thx for the reply
[G2 and Desire Z Android Development] sundar2012:
hows this running with the latest nightly?
[G2 and Desire Z Android Development] joemm:
Super, lovin this kernel, great speed and battery life, running 1200MHz and smartass gov.
[G2 and Desire Z Android Development] sundar2012:
so im able to run this at 1.9 on smartass - 1.9ghz with smartass causes freezes. any idea why? is smartass actually pushing it to 1.9 at any point?
[G2 and Desire Z Android Development] umaro:
Yes, it will go to up to the max speed listed if the CPU load stays above 70%.

A lot of phones can't handle 1.9Ghz.. If yours can't, I recommend not trying, as you can cause damage.
[G2 and Desire Z Android Development] sundar2012:
Sorry, what i meant to say was i can run 1.9 stable on smartass BUT I cannot run it on Interactive. I wrote smartass twice. Interactive is giving me issues at 1.9 and even 1.7 but not smartass.
[G2 and Desire Z Android Development] IharpI:

Hi quick Question , Can I flash this Kernal While Using The Ultimate Droid Rom 3.3.0?
[G2 and Desire Z Android Development] G1ForFun:
Nope. Use a .32 kernel instead of a .35 kernel.

Pershoot has both a .32 kernel and a .35 kernel. I would recommend his.
[G2 and Desire Z Android Development] heybobitsme:
Is anyone else having trouble downloading with this kernel? As soon as I installed it I can't download anything whether on mobile data or wifi.

How is 1.03 working for everyone? any bugs?

I didn't mention it in the OP, but I did get 1.03 to boot a sense rom, which didn't work with 1.02. I think it had to do with ramdisk compression.

Anyway, even after it booted, it just gave me FCs, but if someone wants to try it out, let me know how it goes.

does this work with Xboarder56's rom?
[G2 and Desire Z Android Development] popimp315:
Yeah it does. I'm using it right now. Question....I am confused about this manual undervolting. Very confused.
[G2 and Desire Z Android Development] rickyiswhite:
thanks for the reply bro
[G2 and Desire Z Android Development] popimp315:
So I did it the easy way and udervolted all of then by 50 using the 25 interval change thing from the op's site reference. My question is how do you save the voltage settings or if you can and is there an easier way to do this? I'm all about saving battery which is why I ask. 1.03 seems a lot snappier than 1.02 did.
[G2 and Desire Z Android Development] nik3r:
Permanent Undervolting

Write your undervolting commands to a text file and name it userinit.sh

MAKE SURE THE FILE USES UNIX LINE ENDINGS - you will probably need a little more than your standard Notepad in windows.

adb push userinit.sh /data/local/userinit.sh

or use root explorer

Make sure the phone doesn't crash when sleeping or under heavy loads (streaming video/angry birds) - I recommend making a nandroid backup before you apply the permanent undervolt and use the phone undervolted over a cable for a day before you perma it.

Have fun

PS:

If you run into bootup problems you can solve them by

adb shell

rm /data/local/userinit.sh

immediatelly after the HTC bootup logo show up and phone vibrates, it may freeze one more time if youre slow.
[G2 and Desire Z Android Development] rickyiswhite:
nice kernel works good with xboarders rom
[G2 and Desire Z Android Development] ultma75:
This kernel only works for .35 based kernels. So it doesn't work on sense or miui roms because they are not compatiable. Use pershoots .32 froyo kernel but it won't have smartass
[G2 and Desire Z Android Development] IharpI:
Now Smartass wont go below 768...

...there is no reason to keep it above 200 when i'm just looking on some text or so.
[G2 and Desire Z Android Development] HAK Devil:
Yeah I'm having the same issue with smartass not going below 768 with SuperCM7 2.1
[G2 and Desire Z Android Development] sundar2012:
So right now I'm using the stock cm kernel from nightly 104 w/ interactive - getting slightly less batt life than umaro. idle drain is low if not lower than umaro kernel, but active drain is higher - of course its a different governor and higher (i assume) voltage. However, performance benchmarks are much higher.

Umaro, any plans to merge up cm changes and add support for gui undervolting through existing apps or a new settings menu?
[G2 and Desire Z Android Development] tsubus:
Just installed Umaro 1.03 and it works great! I'm also trying the smartass governor, which seems really cool from the description. Thanks a bunch!
[G2 and Desire Z Android Development] slapshot30:
I'm new to kernals so bear with me, should I only use custom kernals that match my stock kernal? For example, I am on CM7 stable and the stock kernal for that is 2.6.32.28 . Should I only use custom kernals that have 2.6.32.xx or can I use one like Umaro's with 2.6.35.xx ? Thanks.
[G2 and Desire Z Android Development] sundar2012:
if the stock is a .32 then stick with .32. These .35 kernels are only designed for relatively recent nightly builds. If you want to try smartass, blahblahblah made a .32 kernel with smartass and I believe pershoot is maintaining his .32 UV kernel for cm.
[G2 and Desire Z Android Development] umaro:
I will merge in CM changes for 1.04, but there hasn't really been anything significant for our device, mostly for DHD.

So far as gui undervolting, I may have to design my own app for it to work with the sysfs interface we have. All the code written for voltage control/pimp my cpu is specific to tegra devices, and I don't know how to port it.

1.04 should be out today with fixes.

1.04 is uber-snappy and goes all the way to 368MHz, great work!

(Just made my undervolt unstable - crap have to go through 50 frequencies again xD )
[G2 and Desire Z Android Development] tsubus:
seems really good! smartass seems to be working as expected now, it's not stuck above 768mhz anymore!
[G2 and Desire Z Android Development] umaro:
Not sure why it would have made your undervolt unstable, unless you had 368Mhz undervolted too low and it wasn't ever hitting it.
[G2 and Desire Z Android Development] nik3r:
Not your fault definitely, perhaps when you extended the range my settings started to hit frequencies it didn't with 1.03 and these were UVed a bit too much. I already found 2 frequencies that probably weren't previously hit by smartass and my UV was too low for them. I stabilized it by converging on the problematic frequencies by using interval halving and dividing frequencies into groups based on which stress tests they passed - pretty effective method. Still have half of the freqs to go through though.

Oh and Umaro one little detail - I think the smartass scales down a bit too fast. Try to watch a flash video in browser and compare min frequency of 368 and 768. 368 is pretty much useless in this scenario but I understand it's difficult to find the right balance. Maybe some kind of filter estimating load over a period of time before decreasing frequency would help.
[G2 and Desire Z Android Development] umaro:
Interesting.. It should only scale down if the CPU load is under 30%. If you'd like to play with different values, you can check out

/sys/devices/system/cpu/cpu0/cpufreq/smartass

you should be able to modify all of smartass's settings from there. Let me know if you find a combo that works better.
[G2 and Desire Z Android Development] garz:

I'm not having the same results as you guys... battery wise. And I understand there are many variables involved.

After you flash and set everything up once you go to bed turn it off let it fully charge for about 8 hours or so and it should be good that's what I did and worked for me

semi-related question about radio voltages. Does that affect signal strength at all? my bluetooth stereo headset (Jabra Halo) has its bt reciever on the right ear. when my phone is in my right pocket its fine. when its in my left pocket and im walking, the music cuts out - but standing still its ok. could this be related to signal strength in anyway - would a boost in voltage help?

i notice if i have the phone on a table and move away a lot it doenst cut out - so it could be signal dampening from my pants or body too.

You can use ADB to pull the settings, delete the password, and push it back.

The command is :

After you pull it, open it in sqlight program and I believe remove lockscreen.password_xxx I'm not sure what they are named, as I haven't had to do this in some time... I'm also pretty sure there are two of them that require removal.

After you delete them, push that file back to the same spot and poof, no more password.
