[HD2 Android Q&A, Help & Troubleshooting and Genera] Culguy99:
I did some more testing and found out some interesting stuff. In order for me to get the low drain, I have to turn on my phone with it charging and leave it in until android is fully loaded. Interestingly, at this point current widget says 0mA, and in the battery status it still says "discharging" Once I unplug, everything goes back to normal.

HOWEVER, I can keep the low drain until I use the GPS, then, after being done with the GPS and going back to standby, it goes to 56-60. I then have to disable the GPS to get it back to the low drain. I have since added the GPS control to my power control widget.

Seems there are still some fundamental problems I'm seeing between hardware and software, like maybe the os does not fully shutdown the GPS after using. Would this be related to the kernel? Should I start experimenting with new kernels?

Cant find led notification in bangster 1.3a and 1.3b.
[HD2 Android Q&A, Help & Troubleshooting and Genera] reuse:
maybe another solution, i found 5min before... when i was reading this thread found the solution for standby&screen off current 55-60ma,

i have reboot the phone may times , and killed most of the running applicaion, but the current always high. when i recived a call, after, the current seems cutting down to 5ma now..

can somebody comfirm?
[HD2 Android Q&A, Help & Troubleshooting and Genera] hastarin:
There seem to be a few myths about Android power usage so I thought I'd put in my opinion based on my experience using my kernel and build setup (see my kernel thread in my sig for more info).

1. GPS usage causing power drain. GPS can be turned "on" but unless you see it in the notification area up top, it's not actually on and not draining power.

2. WiFi - Again, unless it's actively sending data, or you forced it in to performance mode, it's actually quite power efficient.

3. Live Wallpapers - Yes they add drain, but not nearly as much as you might think. The CPU usage from a live wallpaper is less than that of the system itself.

OK so what does make a difference?

Screen Brightness is the #1 factor. I have mine set quite low (even lower than the power widget sets it on low) by default.

This is my personal experience anyway. I've used SystemPanel (http://android.nextapp.com/site/systempanel) to get an idea of what's using the CPU, and the built in battery information for what's draining that the most.

Oh another tip. One of the apps using the most CPU on my phone is Current Widget. :D So if you really want to max your battery life uninstall it when you're done experimenting.

Looking at logcat it's refreshing it's display every 18ms for some reason.

Thanks Aussie for coming up with this. Got my power drain down to 7 mA in standby.
[HD2 Android Q&A, Help & Troubleshooting and Genera] ridikolous:
I replace the files made no difference, but messed up my keypad lights. Still getting 60mA in standby. So copied back the original system ext file. After that in standby I'm back to 3mA. I was at 60mA on standby after changing to the newest radio. With radio 2.10 I was at 1-5mA. So I guess after changing radio, restore sysext2 file. Worked for me might help others.

[HD2 Android Q&A, Help & Troubleshooting and Genera] avemn1:
Sounds like a great fix to my hd2 battery draining issue. Can you explain a little more in detail about what file to replace and where to replace it. Because my battery drainage issues definitely occurred after i changed my radio on my phone n beforehand my battery draining level was really good. Thanks in advance.
[HD2 Android Q&A, Help & Troubleshooting and Genera] ridikolous:
If you still have the android build u downloaded on your computer.

Take the original system.ext2 from your pc and copy it over to your android folder on your Sd card. It should be under /SD/android/system.ext2. Just replace this file with the original. Just reboot or boot it up I don't know which method u use for replacing the file. I put mines in an sdcard reader.

I found how to switch between 3mA to 60mA. Im using a stock WM rom with an updated radio (without reflashing all) and got that amazing application that enable light sensor to turn of the screen. If i run android after booting in WM I got 60mA ... but if I disable the light sensor program (in WM) and wait for lights of the buttons to go off (not sure if this is related but i always do it) i boot in android with just 3 to 5 mA

Newer evo based kernels and builds with 3rd generation lights file don't have 60ma standby problems.

I have hastarin 6 evo based kernel with mdeejay revolution 1.5 evo based build and I get 5-7mA even when GPS is enabled (but not used)

I don't care about light on/off while booting android anymore.

I don't even need to disable GPS. I still get 6mA.

Older kernels/builds/lights files had bugs and we had 60ma standby even after disabling gps or while lights were not used. It is not a problem anymore. I recommend upgrading your kernel/build.

Hi

I have try to overwrite lights.qsd8k.so with a file manager to solve battery drainage problem and android had freeze instantanetly.

Now the file must be corrupted. I have trying to replace rootfs.img on the android folder but it doesn't work.

I have a black screen after the HTC green splash screen.

What can i do to repair my android?

Please help.
[HD2 Android Q&A, Help & Troubleshooting and Genera] JanssoN:
If your data.img isn't corrupted now, you could try to extract it (just copy it from SD to your computer) and format the SD two or three times. Take 32k blocks for formatting (no quick format). Download a new build (cause the new build have a fixed lights.qsd8k.so :)) and start over. Before you boot android the first time copy your data.img in the Android folder.

Remember: It must be a build of the same developer, otherwise it wont work maybe!

If that doesn't work you have to start from 0 and set it up new.
[HD2 Android Q&A, Help & Troubleshooting and Genera] memin1857:
There is something I have found out.

Although very rare, I sometimes get 60mA bug with my new build.

Read carefully please,

Normally I always launch haret/android when keypad lights are on. But AFTER 60ma bug happens in Android, restarting even with keypad lights on doesn't matter. Trying airplane mode, data, bt, gps, wifi etc enabling disabling doesn't work.

Of the four times 60ma bug happened, I restarted several times but there was still 60mA standby drain on Android startup.

BUT

AFTER everytime 60mA bug happened, if I start haret/android with keypad lights OFF, standby drain returns to normal (5-7mA)

If 60mA bug happens to you and you can't get rid of it, can you try this and give feedback please?

NOTE: I currently have mdeejay froyohd 3.3a build with hastarin 7.1 kernel and 2.14.50 radio with 3.14 based miri winmo rom.

What I suggest is, normally we should launch haret with keypad lights on, but if 60mA bug happens after android is normally booted. (several hours later maybe), restarting it with the keypad lights off is the only fix for me.

I am definitely sure 60mA bug also happens if you enable disable things a lot in Android. (gps, mobile data, airplane mode, bt, wifi etc) Something gets stuck while disabling and you get 60mA. Normally I still get 5-7mA even when gps is enabled but not used.

I suspect light sensor (auto backlight) function in newer builds/kernels may also have problem.

Hi there, first of all, thanks for the post, I replaced the lights.qsd8k file and results to a low battery consum, which I'm really happy to see.

But there's other problem. After I replace the file, the LED on top of my HD2 is keeping light on, no metter I'm charging the battery or not. How to solve this problem, or is there something wrong? Looking forward to the reply ASAP. Thanks a lot!

DUDE! This did the trick, I can't believe it!!! I've been dealing with 60ma battery drains in standby on every android build I've tried, and now finally I'm able to get 4-6ma in standby.

[HD2 Android Q&A, Help & Troubleshooting and Genera] ausun:
I found an always reproducible case. My rom is Mdeejay_FroYo_Sense_v._1.1_Clean. Here are the steps.

1. Check and make sure that the currency is normal (5~10ma);

2. Plug in the headset (important);

3. Launch FM Radio;

4. After FM Radio has finished turning on just press the power button on the top right to close it;

5. Switch the phone to sleep state and wait for a while to have the currency widget update the currency value.

Now the currency is always above 70ma. I have not found a way to turn it back except rebooting. I also noticed that the Mono/Stereo switch in FM Radio has no effect and the sound is always mono.

So I guess the FM Radio application is not talking to the driver in a right way, or the driver is not controlling the hardware correctly. Is it the same with the LED and GPS?
[HD2 Android Q&A, Help & Troubleshooting and Genera] nova hands:
The LED Button trick worked for me, and I got a 6mA reading.

But if my phone goes into standby, I can't get out of the black screen.

I rebooted and made sure the sleep timer was turned off in WinMobile, but it's still doing it.

If I reboot and don't perform the LED Button press while haret is loading, I have no black screen issues, but my mA reading goes back to around 6mA. UGH!

What am I missing here?

[HD2 Android Q&A, Help & Troubleshooting and Genera] aussiebum:
hmmm, u should be able to just copy back. most builds don't have read-only system dir anyways. worse comes to worse u could just restore the original system.ext2 file from download?

oh the flashing led is "normal".. goes away after u charge the phone.

also, can confirm that only lights.qsd8k.so needs to be replaced in hd2froyo v2 build. deleting lights.mahimahi.so causes backlight to stay on, so DON'T delete that file.. if it exists.
