method for fix HD2 SD android standby battery drain 50+ma

This method is suitable for hd2 SD Android, not test on NAND mode. If you encounter problems as the standby battery consumption(50+ma), you can try this method to solve:
If you reboot android and monitor the standby battery drain is 3~5ma,do not happy too early and think that you get a good android rom, because after reboot,it will likely become 50+ma;
If you reboot android and monitor the standby battery drain is more than 50ma, do not despair, don't think that this version is so bad and you need to replace another immediately, because you can use this method below to fix:
Steps:
1, reboot WM, don't hurry, wait 1 minute, let's WM fully reboot, especially some softwares installed on SD but need to run when reboot. press the power button to turn off screen(not shutdown mobile), open the back cover, remove the TF card, the screen will light up, tap the power button again to turn off the screen (not shutdown), wait 10 seconds, insert the tf card, the screen lights up again, now boot android and monitor standby battery consumption, 90% under 10ma ----- In short, that is, before boot android, pull out and plug in TF card;
2, if fail, you need pull out and plug in battery before reboot WM, then repeat the above steps;
If works, please say thanks

Don't charger when monitor standby battery drain, please use currentwidget monitor and use its log function to record. What is "the standby power consumption" pls consult Mr. Google.

Other users reported that changing the sd to another one solved the high drain in standby for them, so you basically are saying the same.
I use the original 2GB card the few times I decide to test android, because first time I tested superram build, my 16GB card got wiped for some unknown reason; I may as well see if your method changes anything.

Worked for me! Tnx!

Had 50+mA wen using android sd, very annoying because in the beginning I had no problems.

Now it's back on 8mA! Tnx!

At first try, this seems to work well. I was getting 60+ ma usage in standby with Darkstone's SuperRAM build, even with a fresh install. Going through this little bit of voodoo got my standby usage down to the 5-8ma range. Thanks for finding this, though I don't like thinking about how much trial and error it took to discover.

I just hope I don't have to do this every time I reboot.

Thanks...

Was getting low power usage through this morning, when I unplugged the phone from the charger. I had left Android running on the phone overnight. I discovered that the HD2 was back to using 60ma when I got back to work. Repeated the magic spell, and I was back down to 8ma in standby. Really strange. Does anyone have any kind of explanation for this behavior?

Wow thx work like a charm.

imrazor - My theory is by pulling the SD card out in WM you stop all applications that use the SD and when you boot android the SD card is only used by android. Well thats what I think ^^

The point is it works and we now have better MA in standby.

Sort of works

The SD fix does take the standby drain to around 7mA, however I can only wake the phone once. The next time I try to power up, my phone never cuts on, and I have to pull the battery.
