60mA drain

Well, as I see it it is definately kernel related and warren has also acknowledged the problem of the spikes some pages back, saying that toggling BT/GPS on and off should bring the drain back to normal.

Other kernel, no problem. It has most probably something to do with the BT drain fix. It looks like some kind of radio use gets triggered. Only on a kernel with BT fix, no one would notice as the part of the radio (BT) doesn't use much drain anyway. On t10 drain also doesnt stay at 7mA all the time but occaisonaly "spikes" to 12mA. But that doesn't really bother or can be called spikes.

I think it is also important to not forget that the problem does not exclusively happen after a call. I had it after I charged my phone and it may also happen without interaction at all.

The one thing that doesn't speak for the above theory is that this is a relatively new phenomeneon, it didn't happen with beginning june or end may kernels afaik, regardless of the BT fix implemented or not.

But then again, even with BT fix implemented, drain was never lower than 14mA with BT on, double the t10 value. I would take t10 as a base and improve on his shortcomings, but I must say apart from undervolt/underclock I haven't found much of those...
[HD2 Android SD Development] TheNT:
I think it's not related... not allways trigered with call but mostlly yes it is...

Juice defender hmmm... tried with it but reading i had was in the midle of falling to 8ma :)

So that's why these 39ma was...

When it felt to 8ma i tried to call, about 15sec conversation and left th phone for 2minutes and drainage was back... at about 120ma... waited 5minutes more and than 8ma :)

But i think the switch is related to charging and discahrging and not juice defender...

Try to put your phone on the current for few minutes than disconect it and see what happens when left it allone at least 3-5min in standby (screen off)...

Please can someone try so i can see is that some kind of solution?

tnx...

Drain calculation

which is the same as I posted, I only had the labels messed up :D

Therefore my numbers are correct, a 60 mA drain will last you roughly 20 hours, thanks for the clarification!
[HD2 Android SD Development] Bazzz66:
Hi Guys,

I am a bit scared to mention the 60-70 mA drain after a call. It makes sense what Copenhagen told me, so I thought I will prove Copenhagen right.

(with a new battery just to be sure)

- After charging this morning 100% (only wifi and data, no bt, no location services, no gps)

- 3,5 hours later, battery 89%, 7mA (checked my mail, looked through my feeds)

- have received and send an sms in the 3,5 hours

- Made a call to myself, did not speak. Back to 7mA

- Made a call to myself, did speak. stuck at 60-70mA

- Wait for 4 hours, no calls (did not do the 0711 update yet), still at 70mA

Noticed that I forgot to log the battery drain. :mad:

I will do this tomorrow, depends on the development later on today..

So I do not want to give anyone a headage, just looking what my problem (and hopefully helping others, there are others) can be. Otherwise I will start tomorrow with complete new image and give myself a call.

Regards.......

I know people will probably flame me for saying it, but I'm a big boy I can take it :)

I just can't understand this obsession with battery drainage, all I seem to be reading about is battery spikes, its becoming boring!

I charge my phone up every night irrespective of whether it needs it or not, and I always get at least a day out of it, so what's the problem?

Get shut of your battery monitoring widgets guys and girls and enjoy the build for what it is, a beautiful work of art. :)

Surely it doesn't take much thought to plug your charger in when you get in the car?

Anyways, no matter what smartphone you have you will always struggle to get a full day out of the battery if you use it all day.

Don't forget this is a HD2 Win mo phone, to have a fully working android build on it is in itself a miracle and great credit to all concerned who got it working.

[HD2 Android SD Development] uzi2:
If problems were not aired and explored, no solutions would be found and the build would cease to develop.

I agree that it is unhealthy to be constantly monitoring your battery widget, but if you had suffered a whole day of 60mA+ drainage, you might be helping to discover the problem instead of being bored by it.

Batt drain

When I put phone to sleep the charge light by the speaker stays on green. I plug charger in for 5 min,take it out, and the light is still on. Sometimes taking phone off sleep,unlocking,relocking makes it go away, but most times the light stays on, and I think that's where the batt drain issue is coming from. Anyone else notice this?
[HD2 Android SD Development] pwhitrow:
HEAR HEAR!... this thread is overun with batt issues. As some of us simply don't get them, do you think it could, perhaps, be down to your own installed apps/usage?

Give Cope and Warren a break. They work tirelessly, for free, for us. What they have produced keeps our beloved HD2's right up at the top of the smart phone food chain, and I for one couldn't be happier with EVERY aspect of their work.
[HD2 Android SD Development] uzi2:
There are so many different variables. Just because you have no problems, it doesn't mean that other people are somehow doing something wrong. Trust me, you will suffer from these battery spikes one day and I'm sure it will change your attitude to these posts.
[HD2 Android SD Development] pwhitrow:
UZI, didn't say they were doing something wrong, just

perhaps

they could be and might like to look there. All in the inteprutation I guess.

I have 'suffered' battery spikes several times. The worst being with NetFlix. Removed the app, problem solved. That's why I wrote what I did.

too bad... again i recieved a longer call and bat at 66ma left...

@eddyedwards007

There is setup that this native winmo smartphone can last for allmoust two full days... more than 24 hours on high usage... and that is the point of mine testing cause i know it can.

I don't want to discredit work of these two guys work cause their work is awsome... that's why i'm stuck in this topic ;)

and their build with someone elses kernel is that perfect combination and i just want to figure it out why... just want to help cause i'm not alone.

Some think that 12 hours is nice, some don't want to talk about it, some don't have that problem and i'm trying to figure out why people are having that isue ;)

Me too among them :)

Mostlly as i can see users that havy use their phones, wifi, data, sync, voice almoust everything included in hd2.

Will continue trying and reporting if cope and waren don't mind...

He knew exactly where it was, just like he knew that build existed. He can speak for himself and probably doesn't need some self-righteous thread police representing him. And as you can see I did thank him...

Back to the build. On a fresh boot up using the magldr rootfs it hangs on the splash screen on the creating a data.img i'm assuming because it never hits the bootup animation nor does it give me the adb prompt on my computer, anyone else having problems booting the 7/11 build on magldr?

Other kernel solves problem but it's not allways that easy to have such statement ;)

[HD2 Android SD Development] kushXmaster:
So a little insight on what I think might be causing the battery drain...(709 build)

For starters I only ever get it at work, where I tend to get sh*t reception (walk in refrigerators and the like.) So to me it seems like its caused by loss of signal and radio reconnecting. I'm usually either at home or work and at home I rarely see loss of signal (data or otherwise) but when it happens typically there will be 60ma draw. However it always goes back down for me. Sometimes its more around 120-135 but I think that is after trying to reconnect while an app was in an update process. Either way, it goes back down for me, even after using proximity on call.

Maybe something to look into? Just my experience.

Also, downloading 711 build now, updating soon. Thanks again ACA team for your blood, sweat, and tears.

I understand what your saying but there are hundreds of posts about the same thing, the devs know about the issue and I'm sure don't need constant reminders.

If you don't like it change builds or go back to Win mo and see which one you prefer.

As for helping to discover the issue, I don't know the first thing about developing or anything technical for that matter, but if you ever need bypass surgery I might be able to help :)
[HD2 Android SD Development] eddyedwards007:

I respect what you're saying, my battery spikes all the time but it doesn't bother me at all I'm too busy enjoying the build and don't need too moan about it.

All I'm saying is it becomes monotonous reading the same people saying the same thing over and over again. Enjoy the build and have fun with it :)

i have a hd2 arriving tomorrow. i intend to install windows phone 7 to nand, and this rom to my sd card. i see that i need to run two programs on windows (mobile i think) before i install this rom. are the programs needed by windows mobile available on windows phone 7, or will i have to install a 6.5 rom, and forget about dual booting windows phone 7 and this rom?

Micro SDHC recommendations (PM me)

I'm looking to upgrade to a class 10 16GB (or really inexpensive 32GB) SD card. I'm looking to keep the price below $40 US including shipping, and of course want speed, stability, and long life. Several newegg reviews are saying that the cards have problems with android devices (but don't mention HD2), so I'm asking here to rule out incompatibility. So who has had good (or bad) luck with their fast 16-32GB card?

Thanks!
[HD2 Android SD Development] uzi2:
There are lots of users reporting good speeds with their class 10 cards, others are more than happy with class 2.

My personal opinion is that it's more important to go for a good name than a high class speed. I use a Sandisk class 4 16GB and it works well for me.

i have those two videos bookmarked, but there isn't any information about my actual question.

from page 1: "Installation & Updating Proceedure is the same!:

Download the build to your pc.

1. americanandroid.7z -> unzip!

2. copy folder unzipped\AmeriCanAndroid\Android -> to -> \sdcard\Android

(COPY THE WHOLE FOLDER.. NOT JUST INDIVIDUAL FILES!!!!!!)

3. in winmo, run clrcad.exe and haret.exe in the \storage card\Android\ folder. OR

(alternatively install exceller bootloader for winmo for one click or AUTO launch of Android OS)"

"in winmo" - clrcad,exe and haret.exe. does that mean i have to have a windows mobile 6.5 rom on my hd2? because i don't think windows phone 7 'supports' the running of exe files, or does it? so would i have to install a 6.5 rom on my hd2, then the sd build of android, and then overwrite 6.5 with windows phone 7 on nand?
[HD2 Android SD Development] kdelisle:
Speaking as one who has experienced odd battery drainage, it seems logical that as some people do not appear to be experiencing the drain, the cause is likely a combination of circumstances, rather than one particular issue in a kernel or build.

Let's try to keep the dialog productive and just state circumstances. One thing is that if you are using an old build, it doesn't seem productive to note battery problems (which might be resolved with a newer build).

I notice that I experience higher drain (+60 or greater) with uncleared notifications. I may try a market solution rather than the default. I'll report back.

i was just curious about the winmo part in the op - so you say to ignore the bit about winmo in the op? i mean, i've seen this: "No Sound in Android: Make sure you run clrad.exe BEFORE running the haret.exe file to boot Android. When you run it, it will not do anything but it does run". from http://xdaforums.com/showthread.php?p=5969936 so i'm asking if i have to run those two exes, do i need a winmo 6.5 rom, or can i run them through magldr? i just want to play it safe here.

by the way, my hd2 has a nand build of android already installed - so if i erase the nand, will that erase magldr, meaning i have to flash it again?

[HD2 Android SD Development] orangekid:
Here's the thing:

you cannot possibly fix something as variable as battery drainage. Not even HTC, Samsung, or Google can do that.

It all depends on radio version, signal, sd card, and hundreds of OS mods and settings. I have NEVER had a battery issue with your ROMs, I do all the right tweaks and every once in a while I notice I'm at 130ma on standby, so I backtrack to see what I installed, if I'm using my old data.img, if I changed anything system-wise, and I usually find some stupid app running in the background.

This is not an iPhone, we are all going to have a somewhat different experience, and it's so easy to isolate a driver, there is no "battery drainage lib" or something that easy.

If it bothers you then continue to try to clean the kernel, but honestly I wouldn't worry about it. battery drainage is the hardest thing in the world for a chef to control and your ROM is by far the best I have ever used, SD or NAND. It may be something in the kernel you missed or some setting triggering some background action we all missed, but it may also be the randomness that is Android.

Any chef who claims great battery life is stretching it because I guarantee there will be people getting 70ma on standby due to some hardware or sd or some other factor.

I get 2-5ma in standby on your ROM...
