Seems like you don't see that this is absolutely different solution than SETCPU profiles, therefor it needs it's own thread and the solutions on this thread is new ideas.

So go whining to other tread, this thread is about helping people in their daily phone experience.

i assume the mattc kernel is in standby, the others while using screen is on? id be surprised it mattc kernel was while the screen was on.

i fresh a new android

this time default all the thing,just change wallpaper to static one and download currentwidget from market.

140mA when screen on with 30% brightness
[HD2 Android Q&A, Help & Troubleshooting and Genera] CB620:
so even with background data off and mobile data toggled off widgets will still try to conect????? thats weird
[HD2 Android Q&A, Help & Troubleshooting and Genera] sylau90:
Don't you feel that your title is match with what you all talking inside?and do you realise that the people inside this thread start to talk about SET CPU stuffs and some basic settings like brightness?????the only difference in this thread is you introduce an app called current widget and the users keep change the setting and see how much current its using...LOL...I not gonna argue with this anymore...

Cheers...I also try to help people as well...but make everything simple...
[HD2 Android Q&A, Help & Troubleshooting and Genera] longobongo:
Thats what happens when people discuss things... You start on a subject which then inevitably moves on to other (sometimes) related subjects. Anyway the original topic says everything we are just using this thread as a troubleshooting exercise to help people firgure out why they are getting more drainage than usual, and suggesting ways to regulate it better.
[HD2 Android Q&A, Help & Troubleshooting and Genera] kivine:
sorry, i just realised the method i used to do the data was wrong, i did the polling every 5-8 seconds.

recommended was 1 min.

I will do the test another time....

but 1 thing for sure mattc's kernel does consume lesser , and runs(very snappy) better :) on hyperdroid for me, u can try and report back for others to confirm
[HD2 Android Q&A, Help & Troubleshooting and Genera] CB620:
i renamed the original and added 2 to the name before .so and than i put the extraction from the zip in the same directory. it said it wasnt enough space but still copied. the keys no longer light up so im assuming it worked. and i rebooted back into android. did i do it correctly?
[HD2 Android Q&A, Help & Troubleshooting and Genera] longobongo:
ill give it a go.
[HD2 Android Q&A, Help & Troubleshooting and Genera] hazard99:
Testing to see how this goes as I felt my battery drain was a little too high.

Thank you for having a vision and being daring enough to try and find a solution.
[HD2 Android Q&A, Help & Troubleshooting and Genera] deli_gt:
Damn you are so TROLL
[HD2 Android Q&A, Help & Troubleshooting and Genera] kivine:
I was told by earlier replies that only intervals of 1 min are accurate. :( So have to redo the tests.

And also how's the experience? both equally smooth?
[HD2 Android Q&A, Help & Troubleshooting and Genera] atmelfreak:
I think it's better to compare only our current values in standby.

All other thinks are not really comparable (data connection, brightness...).

We have here the fact, that users have current values of 5-8mA and others with 50-60mA in standby.

That's the thing we should talking about here!

50mA in standby mean this are 500mAh (milli ampere hours) in 10 hours. This means the battery is nearly half empty in 10 hours

in standby without using the phone!
[HD2 Android Q&A, Help & Troubleshooting and Genera] relic:
I got 60 mah on standby with mattc 1.6b and setcpu.

Better use 1.7 i guess?
[HD2 Android Q&A, Help & Troubleshooting and Genera] longobongo:
i know that i was responding to an earlier post that said mattc's kernel was better at conserving battery. As you can see they are both so similar there is no way to tell if any is better.
[HD2 Android Q&A, Help & Troubleshooting and Genera] longobongo:
basically yeah exactly the same.

i just remaned the 2 files i just added a 2 at the end of them and now im geting 2% standby an our this is compaired to 7% without the changes
[HD2 Android Q&A, Help & Troubleshooting and Genera] vysus:
After several days of intensive testing, I'm quite sure: battery drain depends on SD card.

Me and a friend, XDA user, both verified it using the same configuration:

- ROM: Dutty creme de la creme (V8-9-10) EN|IT;

- builds: mattc Leo 1.4, 1.5, 1.5b, 1.6b, 1.7 - caedanneLEO with mattc build (only me);

- radio: 2.10 / 2.11 / 2.12;

- different ITA providers;

- all data services on (mail time check, Exchange Server, weather, Friendstream, RSS, Google localization, etc.);

- me: a 16 Gb micro SD class 2;

- him: a 16 Gb micro SD class 4,

both from the same vendor.

Starting the devices more or less at the same time, we got different drainage using it more or less in the same way.

We note that on his Leo drain was about 3-4% per hour, on mine 10-15% in the same time.

Completely unuseful to me EVERY SINGLE tweak or suggested configuration found on this forum.
[HD2 Android Q&A, Help & Troubleshooting and Genera] circuithero:
I also got different results depending on which micro sd card I was using.

With the default sandisk 16gb I'm getting just under 1% drain per hour whereas if I'm on the exact same build with a Transcend 4gb class 6 I get much higher drain, around 3-4% per hour.

My Test Setup:

ChuckyDroid 8/11 build

2.12 radio

Shubcraft 1.4d build

all tested in standby w/ wifi, gps, bluetooth, 3G, sync off
[HD2 Android Q&A, Help & Troubleshooting and Genera] anap40:
I had a couple problems with the current going back up to ~60ma after replacing or renaming lights.qsd8k.so in /system/lib/hw. It would go down to 5-7mA after my first reboot but after a few hours or after a charge it would go back up to ~60mA.

It looks like I fixed it by replacing that file and the one in /system/lib with the file posted on page five in this thread. The file on page 5 is called lights.qsd8k1.so and I renamed it in both places to lights.qsd8k.so
[HD2 Android Q&A, Help & Troubleshooting and Genera] aussiebum:
How about installing some battery monitoring software like Current Widget and use it to figure out what app(s) are chewing up your battery life? There's only so much tweaks or config changes can do. If you're getting ~60ma drain when the screen is off then you could be having the same problem as quite a few other people on this thread, ie. buggy hardware libraries. Try another Android build and/or patch it with the hack on page 5 of this thread and see if that helps.
[HD2 Android Q&A, Help & Troubleshooting and Genera] aussiebum:
glad to know that actually works :)
[HD2 Android Q&A, Help & Troubleshooting and Genera] aussiebum:
Awesome - I haven't bothered trying the led light hardware library workaround/fix out on mattc's builds since quite a few people were reporting they had no standby/screen off power drain issues (since they were all saying they had ~10ma drain, which is acceptable/normal). Might give that build a go tonight and see if the workaround/fix helps without breaking too many things :rolleyes:
[HD2 Android Q&A, Help & Troubleshooting and Genera] bigvandal:
Hey Im running MAttc 1.7 also but Icant find the folder that contains the file to replace. Where is it? My battery drain is horrific
[HD2 Android Q&A, Help & Troubleshooting and Genera] anap40:
Actually it has jumped back to ~60mA, not sure why though

EDIT: I take that back. Another reboot and it is back down to 7ma, without touching any of the .so files. Something weird is happening but it is deffinitley related to these files.
[HD2 Android Q&A, Help & Troubleshooting and Genera] sylau90:
-1...Agree with you...make things complicated and repeated many discussions/threads out there...zzzzZZZ...

Battery drainage is heavy,why?

1)we boot android from SD card

2)personal usage (DATA,Brightness,GPS,programs running in the background,WIFI&etc...)

3)processor speed(MAJOR)

4)build you using...

5)android on htc hd2 still under development...

LOL...cheers...

ATM, learn more about SETCPU setting and set task killer auto kill(WHEN SCREEN OFF) will save your battery a lot...Happy tracking the current you use...maybe it could be a good experiment about how many current your device using to open this and that apps...
[HD2 Android Q&A, Help & Troubleshooting and Genera] Hd2Menace:
err why am i getting 100-200+ mA?
[HD2 Android Q&A, Help & Troubleshooting and Genera] anap40:
You are missing the point completley because of your closed head, you obviously haven't read this thread.

Some people are seeing 50-60mA draw during standby and others are seeing 5-10mA. The problem has to do with some .so files that control the lights. When people with 50-60mA draw remove or replace these files they cut their standby current draw by 10 fold.
[HD2 Android Q&A, Help & Troubleshooting and Genera] anap40:
We are comparing standby current draw.

Set the update interval to 1 minute and then turn the phone screen off for a few minutes and when you turn the screen back on check what reading you get.
[HD2 Android Q&A, Help & Troubleshooting and Genera] Back Stabbath:
im still wondering what software you guys are using to get into the system file. im probably missing something but im not able to just open and replace parts of the file at will expecially the opening part and not sure what i should be opening it with in the first place. im gonna attempt it with "disk internals" so im sure my next post will start something like "OMG!WTF!LOL!I BRYK3D MAH PC!!!...."

if someone could suggest some software for me id be happy. im on win7...

I have noticed that when I press the power button to switch off the screen, it switches off but the backlight stays on - which is causing the increase in power consumption. The buttons at the bottom of the phone no longer light up either.

Can someone post a link to the other .so (the one that we're supposed to replace) so I can put that back on my phone?

Ok, excellent thread.

Just renamed my lights.qsd8k.so to lights.qsd8k2.so rebooted and voila 3mA in standby...

Was getting 54mA before this patch in standby.

SetCPU is set to on demand and advanced task killer is off. Display @ 40% and 2G reception. All data, wifi, etc off.

Running Schubcraft 1.5 and loving it. Apparently I heard that Froyo 2.2 kills appz so no need to run advanced task killer.

Anyhow 3mA I am very happy. Hope this helps others maximise there battery usage. Running a Class 4 Kingston 8GB card.
[HD2 Android Q&A, Help & Troubleshooting and Genera] kardas666:
Use Droid Explorer to replace files. Also, in Shubcraft 1.5, I had to drop file in both locations: /system/lib and /system/lib/hw to see the difference.

Usage on standby droped from ~60 to ~6. I'm happy. Thanks for messing about and finding this, even tho how you managed to think it up elludes me.

[HD2 Android Q&A, Help & Troubleshooting and Genera] xlr8me:
I'll also add for the last few days since getting this build charging it took forever and I can now see why 54mA is sapping a fair amount of juice whilst charging in standby.

I am quietly confident now that charging should be much faster to reach 100%.I will update this post to reflect observations/experience.
[HD2 Android Q&A, Help & Troubleshooting and Genera] kaymado:
yep... you may be right (LAMO), the difference is that WITHOUT any widgets (shubcraft 1.5)I had 50% drop over night, while in previous shubcraft builds, I was having 1% drop per hour WITH widgets!

If you have nothing interesting to say, dont say it!
[HD2 Android Q&A, Help & Troubleshooting and Genera] aussiebum:
Ah, you've deleted the backlight/keypad control library file instead of the notification led library file.

Different builds name/implement the backlight/keypad file differently it seems, so you have to be careful and just experiment around.

In HD2Froyo V2, the backlight/keypad lib file was called lights.mahimahi.so... not sure what Froyostone (v1?) uses. If the /system/lib/hw/ dir only had the file lights.qsd8k.so, I'd be really cautious about just flat replacing/renaming the file.

I suggest restoring the default system.ext2 in your Android build to fix the problem (that's why I said make a backup 1st in my original post!).
[HD2 Android Q&A, Help & Troubleshooting and Genera] aussiebum:
Cheers, I updated my original post on http://xdaforums.com/showpost.php?p=7949689&postcount=42 to mention Droid Explorer and the other possible location of the lights file.

How did I realise this workaround? Well I've been following this HD2 Android thing for awhile and noticed I suddenly got ****e battery life after moving from HD2Froyo v1 => Froyostone v1 / HD2Froyo v2 / Shubcraft v1.... so that's when I got frustrated and started poking around :)
[HD2 Android Q&A, Help & Troubleshooting and Genera] aussiebum:
10MA is pretty good you know.. that's what I get sometimes too (I'm hovering between 5ma-13ma on standby). If it annoys you, do the Android energy-saving basics and turn off stuff like Background Downloading in the Settings.

The standby power drain also got nothing to do with the sdcard. I'm using a Class 6 16gb Transcend btw.
[HD2 Android Q&A, Help & Troubleshooting and Genera] aussiebum:
That's weird. I just installed a fresh build of MattC 1.7ppp, installed SetCPU and set Conservative CPU Governor, disabled AutoSync and Background Sync options in Settings and got rid of the Live Wallpaper for a static one and put Current Widget on the desktop.

Result? 11ma idle.

So the notification led library problem doesn't seem to affect MattC's 1.7ppp (with Sense) build, at least.

Hey guys,

Using Shubi's 1.5 RMNET and checked the date of my lights file - it was the mid-August and I had ~60mA draw on standby, so went ahead and replaced in system/lib/hw and system/lib.

Did a reboot and it seemed to be OK. Checked it almost immediately and the drain had dropped to 5-6mA. :)

Left it a while - think I did another reboot in there and now it's back to ~60mA... :confused:

Strange....
[HD2 Android Q&A, Help & Troubleshooting and Genera] ohhyeahh:

[HD2 Android Q&A, Help & Troubleshooting and Genera] wheeliemonster:
OK- now it's got worse. No reboots since but in standby I'm getting drains of ~100-200mA with Data, Bluetooth and everything switched off - I've lost about 13% in the last hour.

[HD2 Android Q&A, Help & Troubleshooting and Genera] anap40:
Make sure you replace the lights file in both the /system/lib and in the /system/lib/hw folder with the one aussiebum posted earlier in this thread. Make sure you rename them both to by removing the "1" before the .so
[HD2 Android Q&A, Help & Troubleshooting and Genera] Machiel187:
Added the lights file. Didn't change much. Someone mentioned removing facebook and twitter widgets. That did change my current to 4ma in standby.
[HD2 Android Q&A, Help & Troubleshooting and Genera] wheeliemonster:
Thanks but I did do exactly that.. Both my .so files in system/lib and system/lib/hw are now dated today so they're definitely the new one... (No 1 on the filename either)

[HD2 Android Q&A, Help & Troubleshooting and Genera] kardas666:
There's a post few pages back what to do if you mess up, think it involves replacing ext2(something more here) from original adroid download to get the whole /system back.

Also, don't be discuradged to try mess around, think I saw a post somewhere that said some file explorers and terminals mess around with permissions in android, so that might be your problem. Try others. Droid explorer worked for me.

As Anap40 mentioned, don't just rename/delete the file. It needs to be replaced! Deleting or renaming the file just causes the issue you mentioned.
[HD2 Android Q&A, Help & Troubleshooting and Genera] aussiebum:
hmm, personally I wouldn't recommend overwriting lights.htcleo.so. I believe that it might perform similar function to lights.mahimahi.so on HD2Froyo V2 builds... ie. Screen blacklight / keypad light control.
