I am running [BUILD][02.09.2010][FroyoStone Sense - V2][Kernel: darkstone 2.6.32.9 #3] and typically got a 3-6mA draw while in standby. I was playing around with Google Maps + GPS today and suddenly I was stuck at ~60mA even if I rebooted (as noted by multiple users in this thread). I even turned off GPS and saw no change.

I renamed lights.qsd8k.so and can confirm that my draw is back to around 3-6mA again. Also, my hardware LEDs still work after renaming this file AND I left GPS on!

If you are running the above build, you might want to just try renaming the above file and see if that fixes it for you (per the suggestions noted in this thread).

Copy error

Hey guys!

I tried to copy with astro the file "lights...so" that was attached on post #42; but it gave an error:

Copy error:

java.io.IOException:

No space left on device

And the file copied is 0 bytes!

I have a stock 1.72 WWE ROM

2.12.50 Radio

Mattc 1.7RMNET version

What should i do to replace it?!

Clicking the superuser permissions does nothing!! (Black screen, even if i hit preferences)

Please advise,

I'm getting excellent battery life again with Xcelsior (24 hours since a full charge, now at 55%). The only thing I did differently was I ran Tom Tom (from the storage card) before I booted Android.
[HD2 Android Q&A, Help & Troubleshooting and Genera] hoobledi:
your problem sounds vaguely familiar. try using droid explorer and turn mass storage off before removing the usb cable after copying your files.
[HD2 Android Q&A, Help & Troubleshooting and Genera] patton82:
I use the same build and battery drain in standby is 60-65mA. Renamed lights.qsd8k.so to .bak don't change battery drain
[HD2 Android Q&A, Help & Troubleshooting and Genera] Sjuust:
I just copied lights.ko from zip on post 48 to system and also chmod 755 (don't know if that's needed ) just like modules. It fixed my battery drain! Got 3-5Ma in standby: ) (also latitude disabled )

I'm on darkstone froyo 2.1 and michy's kernel r10. Also imported latest wifi modules and firmware.

..after 15 minutes of use the drain is back to 60 mA..grrr ;(
[HD2 Android Q&A, Help & Troubleshooting and Genera] deli_gt:
Thats strange, I only get 60ma if I don't boot straight to android.

Try to boot straight with EBL2.1 auto-boot 6sec.

That solved my problem, if I use WM for even 1 min i'll reset it and let it auto-boot.

Bye the way what MicroSD you have?
[HD2 Android Q&A, Help & Troubleshooting and Genera] deli_gt:
What is your MicroSD, seems thats the problem.
[HD2 Android Q&A, Help & Troubleshooting and Genera] kinga33:
me to no matter what I do it is 59 - 62 mA
[HD2 Android Q&A, Help & Troubleshooting and Genera] deli_gt:
Just believe me IT'S MICROSD PROBLEM!!!!!

I have tried many different and know what is best.

I don't even need to change led files and still get 4-9ma when idle.

[HD2 Android Q&A, Help & Troubleshooting and Genera] patton82:
Peak 8Gb class 6

I tried to change build with mattc 1.7 ppp, power consumption in standby is the same (62-68mA), GPS disabled

now I'm going to try auto-boot loader
[HD2 Android Q&A, Help & Troubleshooting and Genera] deli_gt:
If that doesn't work it definitely is your sd
[HD2 Android Q&A, Help & Troubleshooting and Genera] patton82:
From winmo I edited this registry key:

HKLM\Drivers\SDCARD\ClientDrivers\Class\SDMemory_Class\High_Capacity

DisablePowerManagement=0

And now standby power consumption is 8-9mA (instead of 65-68mA) with mattcfroyo 1.7 (and GPS enabled)

That was the problem :D

Its great with shubCraft 1.5 PPP and low power consumption 3ma to 8ma only ;)
[HD2 Android Q&A, Help & Troubleshooting and Genera] faisalee:
Most Android Friendly ROMS already have that + a few more flags already set for you to get great battery life right out of the box!

But good to know it actually works :p
[HD2 Android Q&A, Help & Troubleshooting and Genera] simeezee:
Maybe i will give KWBR 4.5 Android Friendly COM2 a try.
[HD2 Android Q&A, Help & Troubleshooting and Genera] Mik0:
This has worked for me! Thanks! With any particular build, it was a hit & miss whether I would get 60mA or 6mA on standby. I would find myself scratching my head why at one time I would get low mA and other times high mA.

Now, I have found that *once* I have booted into Windows I would *immediately* boot Android and

enjoy low mA standbys

.

This is the only thing I've experimented with so far, with a few builds. Hasn't failed me...YET! (knock on wood).

Give it a shot!
[HD2 Android Q&A, Help & Troubleshooting and Genera] xlr8me:
I found SetCPU buggy after a day or two was again after rebooting going up to 58mA. So I have since gone back to the keypad light method on booting into android.

Un-installed SetCPU and now nice and low 3mA in standby every boot.

ENjoy :)

No setCPU ... No TaskKiller ... GMAIL Full On ... Weather Full On ... Twitter/Facebook Full On...

[HD2 Android Q&A, Help & Troubleshooting and Genera] simeezee:
Just want to share my experience. I have tried so many ways of tweaking and replacing files. I was finally able to get to around 3-8mA standby battery drain.

But whenever a text message comes in, my battery drain will kick up to 60mA right away. If I don't read the text and leave my phone there. It will be 60mA from then on.

If I open the text then turn off the screen. The battery drain will go back to 3-8mA again.

Does this mean high battery drain during standby could be triggered by some specific application? Can someone explain this to me?

Thanks.
[HD2 Android Q&A, Help & Troubleshooting and Genera] Sjuust:
Booting straight into Android fixed my battery drain too!..At least so far ;) I used this
[HD2 Android Q&A, Help & Troubleshooting and Genera] hoobledi:
Out of interest, I installed Bangster´s v1.2 today. sure enough, the same high standby drain as in the other builds I tried - but also the same working fix: location & security -> GPS off. Of course, background app sync is off as well. Also replaced the lights files.
[HD2 Android Q&A, Help & Troubleshooting and Genera] arned:
I could imagine, that a text arrival is a trigger for LED to start flashing. As soon as you have opened the text, you don't have any new unread messages anymore -> so the LED could be disabled again... So this points again to a problem with LED lights.

I think this all is controlled by the system, not by an app. Apps only tell the system to enable/disable LED.

Maybe this behavior is also the case, if new emails arrive. That would explain, why the standby drain issue sometimes returns.

I couldn't fix the drain issue at all. I tried all workarounds (lights lib, winmob reg tweaks, cpuset...), except using an other sd card (but i will test this today)

Regards

Arne
[HD2 Android Q&A, Help & Troubleshooting and Genera] hoobledi:
it´s important to note that when starting / restarting android from winmo in order to get low power consumption in standby, you have to do that right away, first thing you do when winmo is up,

as quickly as possible

otherwise you´ll still have high drainage in android´s standby. speaking from my own experiences only of course. this seems to have more impact than whether lights are on or off when starting android.
[HD2 Android Q&A, Help & Troubleshooting and Genera] arned:
I just tried this APP: "[APP] Android Loader v4.1 for HD2" (in this Forum) AND: It did it ! This is the first time, my froyo darstone v2 (2010-09-02) only needs 7mA in standby.

EDIT: I'm not sure, but maybe this app is loading darkstone v1. It is also on the sdcard (folder Android_Old). I choosed the correct folder of v2 in setup, but I'm having bugs now, I only had with v1.... I'll delete Android_Old folder and try again

Use Estrongs file explorer. In settings, root options turn on Root Explorer and Mount file system. Then you can copy and paste all you like.

Turn off the root explorer when you're finished, or it'll force close the next time you try to run it.

This has worked great to get Android "running" with 4-6mA standby. After ~1/2 use I was back up to ~60mA standby. In another earlier post I have read that a member mentioned GPS caused this increase in standby consumption. He was right; I turned off GPS (settings->location & security settings, uncheck Use GPS satellites) and my standby has been at 4-6 mA for more than a day now!

[HD2 Android Q&A, Help & Troubleshooting and Genera] kry0bas:
Hey guys, thx for the tips and tricks to get the heavy battery drain killed!

tried everything u said, but my idle drain still jumps every 5 minutes up to 150mA! And stands there for 5 minutes (standby battdrain ~ min 5%/H)

used the light trick and the immediately start after winmo boots, but nothing helps!

My Solution:

Uninstalled Taskiller (someone said that in this forum before)

and uninstalled SetCPU! After killing SetCPU and rebooting straight into android, my idle drain falls down to 4-9mA(and stays there! no peaks anymore:D )!

android: bangster 1.2a

radio: 2.12.50.02_2

SD Card: Panasonic 4 GB class 4

standby: now 4-9 mA *happy*

IMMEDIATELY after winmo is ready, try pressing the home button twice, before you launch android from within WinMo. you want the lights to still be on when you see the android boot-up.
[HD2 Android Q&A, Help & Troubleshooting and Genera] ugumba:
Try using OSMonitor to see if any particular process is running in the background. 200-400 is way in excess.

Sorry to ask, but are you sure you didn't see those values while charging (i.e. positive values)?

Also note that the readout on the widget is almost meaningless - check the CurrentWidget log file after 10 minutes of idle, screen off, discharging, GPS off, no task killers, no SetCPU.

My settings - working well

Hi All,

I've had some success in getting good battery life.

I'm using Shubi 1.5 but with the latest MichyPrima kernel which supports the interactive CPU governor.

I'm also using the lights-on-when-boot-android trick whenever I boot from WM.

I've got my SetCPU set as follows:

Temp>50.0C 499 max 245 min Priority 100 conservative

Screen Off 245 max 245 min Priority 95 userspace

Charging/Full 1113 max 245 min Priority 90 performance

Battery<25%	460 max 245 min Priority 65 powersave

Battery<100% 998 max 245 min Priority 0 interactive

Just thought it may help someone - seems to be giving me better life than any other things I've tried so far. It can get a little slow to respond here and there and I get the occasional non-responsive touchscreen but I think that's more down to the fact that I leave auto-rotation on than anything else!

Hi there,

Thanks in advance!

I have hd2 froyo with latest kernel

No gsensor but got good led notification files.

Battery Now I have 33 % and it is on for 21 Hours.

Curent widget 5ma every time i unlock it.

Why it is so good dunno but in set cpu i did a trick, go where you select speeds and take g1 sppeds then create sleep profile with dunno <20 mh. I love my phone now it is fully usable but waiting for fix on gsensor, navigation update and that's. IT will be included in new darkstone build hd2froyo.

I just ran a freshly installed version of WinMo on my HD2 and battery life is stupendous...

For 8hrs standby ~ 3% battery loss..

Compare this with Android

For 8hrs standby ~ 10% battery loss (3~5mA standby)

Still not bad but certainly having Android on NAND would be a whole lot better.

I am more in love with My hd2 than I was before. after hitting the 12 hour mark yesterday and still having 44 percent battery left I was amazed.

Only thing i try to avoid is having any widgets that are active as they cause my ma's to rise.

sd unmount/slipstream

im going crazy with this sd experiment which brought me into crazy bussiness:

while on froyostone v2 with 8gb running well with 8mA , i unmount the sd card and quickly replace it with 4gb with the same content of android because i have mirrored both cards. then android prepares sd cards and it still runs

the battery drains still the same 8mA but it seem to life longer. eventually it live for 2 hours until i hit wifi on and it freeze totally :D

then i reboot again with that 4gb load it up, un mount again blabla reverted. with 8gb again... prepare sd card.. android going sooo fast.. and it freeze totally :D

I had been getting 60ma for a few days now.

Today I uninstalled all apps which I no longer use, downloaded auto killer and set to aggressive and restarted and now its down to 3-5ma.

[HD2 Android Q&A, Help & Troubleshooting and Genera] xlr8me:
I have been trying the keyboard method for a few days and it has worked ok until today.

Been getting the 55mA now consistently with keyboard method. One thing to note is that the LED was flashing when booting into android when this problem started. Now booting in and the LED does not flash.

Weirdness...

EDIT: Discovered something interesting...

If the battery % is below 92 then the power management will enable 5mA in standby. However, if you boot into android and your battery charge is above 92% then the 55mA is consistent.

I need others to confirm this...but it looks like this is what is causing it.

If you find your standby current was 60mA, don't reboot, please do some simple steps as below , you will be back to 5mA.

Then back to up level press Flash test.

Finally! Confirm this, someone.

Ok, I need to post, because after 2 days of testing different builds/ radios/ etc. I finally have 5mA standby with 3G on.
