idle process

Hi, i've noticed that my hd heats up really a lot, and at the same time i realised that in task manager a so called "idle process" it's allways at +80% from processor speed.
Do you think it's sometinh to do to the fact that the device it's allways hot (even wen in standby) and the batery drains relatively fast and also the fact that it takes ages to charge. I've allready sent it on repair and received it today with stock rom 1.56, but the problem remains spite they've said that everything was ok...
I've flash the Dutty's V3.3 XT and on the task manager i've noticed that idle process... it makes me wonder...

Don't wonder.
The idle process isn't doing anything. It is certainly not the cause of battery drain or heat.
It's actually not even a process, just a "counter" telling you how much of the processor is doing nothing.
If you look at the task manager in your own computer, you'll see that it also has an "idle process". It's the same thing.
For more information regarding the idle process just google "Idle process" and you'll get a ton (actually about 409,000 ) hits...

You can use an application that can monitor current drawn from the battery to see if you have an issue. There are many apps that can be used - i use phone alarm from pocketmax.net that acts as a profile switcher, but has many additional functions including power monitoring and battery temperature.
Typical values that i see are as follows
Idle (no apps running) radio on, wi fi off, screen set at level 2 --> around 84 - 100mA
While browsing the internet via wifi, this typically increase to around 170mA
While browsing internet via 3G this can increase upto 350 - 500mA peek.
The touch HD can get very warm when in use.
Hope this helps

Your not the only one mate, my phone has just started getting stupidly hot and running down the battery stupidly quick and taking ages to charge!

The thing is, its getting very warm with NO USE. It can run the entire battery flat in less than 12 hours with NO USE.

Simple Trick To Get 4-11ma In Standby

First, sorry for the new post on this, but I have not seen this mentioned. Didn't want it buried before it could help anyone.
I have used pretty much every android ROM out now, and for some strange reason they each have one constant.
ROMS which give 54-67ma on standby on first boot can be reset a couple of times until they reach the 4-11ma in standby point. Usually takes 1-3 resets.
Now, I'm not sure why this is all I know is it works. And yes, there is a huge amount of difference between 5+ and 50+ma.

I can surely confirm this

This is most definitely true, might sound illogical or fake but I personally took battery logs when my drain was 58mA but could not find anything, I changed Kernels just to observe the same and I finally gave up but I accidentally had to reset my phone a few times as I forgot to put it on charge/freeze then after a few days I happened to see terrific battery improvement 5-8mA, I didn't know why but then I understood it was because of the resets..

Good to see I'm not going crazy. Like I said, I tried this with a bunch of different ROMS. All the same.
So if you are having bat problems. Try a few resets and see how that works for you before giving up on the ROM.
Oh, I might also mention I am not running any sort of set cpu app.

Check again

Funny that just the both of us are populating this thread.. But yes I too do not use any Set CPU or Task Killers..
Currently on
Mattc Leo 1.8 with hastarins r7.6 with 5-7mA battery drain on Stand by (Wifi, GPS,Bluetooth off, data on(but disconnects sometimes))....

I can confirm this too.

Im a little new to Android on the HD2, running Mdeejay eVo Sense v. 2.3 rEVOlution 7.7 Hasteran at the moment.
Im finding the battery life on v2.3 less then on v.2.2 so I'll try a few resets & see if it improves, thanks.
Oh, is it really necessary to run SetCPU or a task killer?
Im forever closing tasks with task killer & the though of a task being auto closed when I turn the screen off is comforting, but is it best to just leave things to the kernal?

The most consistent way I have found to get 4-5ma on standby was to use exceller's android loader set autoboot android and 3 secs.

I can confirm this too.
I am trying dual boot (http://forum.xda-developers.com/showthread.php?t=723200) to boot into Android right away to see if that leads to more consistent standby battery drain. (this was mentioned on another thread.)
I have abandoned TaskKiller and AutoKiller, made no diff in battery drain for me.
I so still use SetCPU to slow the CPU when battery gets low.

For better battery life, setCPU is a MUST! Creating different profiles to change the cpu clock is huge in conserving battery; especially, the the screen off profile.
Ditch ATK and download Watchdog instead.

even hastarin himself is using android without setcpu. with kernels 7.6, 7.7 I get same batt juice as with setcpu, BUT less stuttering in general, i.e. android runs more smoothly.

Honestly I have found that every ROM I have used set cpu was a detriment to battery life.
I'm still not 100% that even task killer is helpful in some cases. I think that on the other hand has to do more with how you use your phone and what apps than anything. Some people can prob get away with it.

SetCPU is pretty much pointless now with the latest kernels, only thing it's useful for is overclocking, but even without it I've not found anything that can't run. Even graphically intensive games like Reckless Racing run perfectly fine at stock CPU speeds.
I've just updated last night to ShubCraft 2.0 DropMode and I get 6ma in standby, my battery dropped 9 percent in 8 hours of standby while I slept, and after a full day of using my phone from about 9am to 6pm tonight (texting, calls, wifi use, 3G use, picture taking, playing a few games and listening to over an hour of music) my battery only just hit 50% at 6pm. This is without SetCPU.

What i've done is just swap out the micro sd card for another one. I had the stock 16gb and replaced it with an 8gb micro sd card and i'm getting fantastic results.
Without any type of task killers or Set Cpu, i'm constantly getting 3ma - 9ma stand by readings from Current Widget.
I also downloaded Juice Plotter from the Market ( what a fantastic app IMO ) and it tells you how much time you have left on your battery as well as a graph detailing the percentage of power battery has used.
I can go a day to a day and a half with out charging my phone. I am in complete Android Heaven.
NOTE: Keep in mind that when booting into Android, when you hit the Haret, make sure that the hard key light are on.
I also have the auto sync off to save battery as well.

To get the 4-11 mA, just make sure the keypad lights on the phone are on when booting haret.(pretty much, boot asap)

After several reboots this is holding true.
Before when I making sure the keypad lights were on before booting Android I would still occasionally get bad standby drain, so I think that is myth.

Exceller's auto boot app = no battery drain!!!

GOLD!!!! PURE GOLD!!! Been trying to preach this for days now! The battery drain is eliminated by booting Android before WM/Sense fully boots. Has nothing to do with keypad lights being on or off. Hence, use Exceller's auto boot app set to boot 3 secs and restart your phone and let it auto boot. Battery drain ELIMINATED!!!!!

[Q] Battery Issues;BSOD/SOD;EBL?

So, I'm at a loss of what to do here. No matter what settings I seem to use I can't get good/decent battery life.
In fact, I get terrible battery life. With light to moderate usage I have to charge my phone at least two times a day, mostly three. Current widget reads that at standby I'm anywhere between 55mA-70mA and when in use 200mA-500mA. When charging it reaches 400mA-600mA
I see everyone talking about being able to get 5-10mA and I'm amazed at this. I've searched and read most "Battery saver" threads and none of it seems to work.
I was originally using Chucky rom lite and when I noticed the drain was abnormal I switched to the set up that chiasoft uses in his ReadMe for the ROM (stock 2.10ROM/2.08 radio).
Although since switching to the stock WinMo ROM I had repeated BSOD and SOD issues. To the point that it became unusable. I switched over to latest Energy ROM.I installed EBL and on both Stock and this Energy ROM. I am still having BSOD/SOD problems. Could it be the EBL? I plan on upgrading the radio to 2.12 in a few after I test out this EBL theory.
My setup as of this post is this:
WinMo ROM: Energy.BLACKSTONE.21916.Sense2.5.Nov.08 (Switched back to Stock 2.10)
Radio: 2.08.50.08_2 (Switched to 2.12)
Android: MooMoo Froyostone Sense 3.2 w/hastrain kernel
SetCPU:
998max/245min Ondemand on boot
Profiles: Screen off; Priority 100; 384max/245min ondemand
Battery <25% 576max/245min Priority 0 ondemand
Sampling 20000; Up Threshold 40
Advanced Task Killer:
Kill Level Agressive
I really don't want my LI-ON battery to die before I've even had the phone for the year. So if anyone can think of anything to help I'd be ever so grateful.
And of course, thanks to all the people who make all this possible.
(Sorry for the tl;dr post. I wanted to give as much info as possible.)

when you fully charge your batter what is your mV ? use the battery life widget to determine this. If it is not nowhere 4000mV once fully charged, you might need to consider buying a replacement battery.
btw. my mA reading is actually worst than yours. Might have to calibrate the battery again later.

idk what it is fully charged. I'll be sure to check it later though. How do you calibrate the battery?
Also, I realized that I made an oversight on my part. When I switched to the stock WinMo rom I hadn't realized fully that it changed my Radio to 2.08 even though I posted it.
The rom chef recommends 2.10ROM/2.12 Radio, so that's what I switched to to check out that combination.

btw change it to interactive not on demand.
you charge the battery when your phone is off. Till your charge indicator turns green.
Once that is off. you can use root explorer or adb and go to rm/data/system delete the batterystats.bin leave your phone plugged in while you are deleting the batterystats.bin file
i prefer root explorer. but its not free and your device has to be rooted.
let the phone drain the battery till its dead and turn it on again to make sure it is completely dead.
charge the phone like you would usually afterwards.

Yeah. No interactive settings. Also, that guide recommends 1190 max, but mine only goes up to 998.
Also, I finally got it to down to 7mA in standby. When I changed the radio to 2.12 and using a 2.10 stock WinMo rom.

no issues here getting 48 hours of light use, or a full 24 of moderate use...

I've yet to "condition" my battery. I'm worried it'll do more harm than good. Especially since I just got it finally to a decent mA draw. Although I'm worried my phone won't charge up to 100%. Always stop at 95.
Is conditioning really necessary/important?

easy answer... whats your full charge voltage? shuld be 4.2
if not , your looseing batt life..

yes full charge voltage should be around 4.2. Try charging it with the phone OFF till your charge indicator is green. This way you can achieve a full charge.
By the way how the hell are you getting 48 hours on light usage?? excuse my language. What are your setcpu settings, configurations. etc.

Yeah, 48 hours seems improbable. I finally got it down to 7-10mA on standby, and I think it charges up to 4.2 but I'll find out for sure tonight.

same
I had the same problem, make sure you use EBL android launcher and set to autoboot at 3 seconds. Make sure you restart your phone anytime youw ant to load android. I assure you this will work.

My HD2, like all others can be flattened in 2-3 hours with windows/android if used hard, the difference seems to be on very light usage/standby win mobile could last 4 days... with everything turned off and basically not used Android would struggle to last 2 days !
Same phone same network/signal levels etc, can only be poor power management within Android, and I think that means voltages for all the processor and comms modules, not just a simple case of turning down speeds.
What do others think ?

Update: Upon switching to WinMo:2.10 and Radio:2.12+ MooMoo's MMS fixed froystone3.2 I was achieving 6-10mA in standby. The phone would last all day with a two-three hour charging period with moderate usage. Low battery use, rare DC's. Perfect. Best build I've used so far.
I'm noticing a new problem however, and I wonder if it's happened to Chiasoft who recommended this build. I'm getting serious touch screen freezes since last night. Anytime before that the set up was working AMAZINGLY.
Now? It's almost unusable sometimes. This morning it was happening in Android so I switched to WinMo and surprisingly enough it happened in there too. So I read touch freezes are Radio problems mostly. Is this true? Should I switch to a new radio? I'm confused as to why it would just randomly start happening though and worried it would mess up my battery troubles I just solved.
Any advice?

Hmm. I noticed that it almost always freezes when I hold down the end home button to turn off the phone or data or to silence it. I can't actually use the touch screen again until I hit the button again to put it to sleep.
I wonder if it's hardware related because it was happening in WinMo that way as well.

Okay, so now the entire adroid system is acting up mostly related to the touchscreen. Like I use the calculator and it appears that i'm holding a button down. Or I try to make a call and it's not responding. It appears that when I hit end call button repeatedly it allows me to unlock the phone. But when holding down the end call button to get to the Power Off screen nothing in that menu is responsive.
It seems... software related, but I'm not sure. Any info would be helpful. I'm going to reformat my card and reinstall droid and see what happens.
So, called t-mobile. They're sending me a new replacer phone. Oh well. We'll see how that one goes.

I give you only a very short suggestion
You have just to DELETE SETCPU
and delete ANY TASK KILLER (you can keep it just to close any apps that could hang, but not to "free up ram")
Android is not Windows, you dont need to free up ram, and you dont need to overclock/undervolt to gain some minutes of battlife despite stability.
Talk to any Dev and they will confirm this.
Good Luck

Battery - energy loss or charge? Age - recycles from deep discharge? Plugged for longer than needed? Air temperature or silicon cased? Temperature with heavy energy drain?

As far as software goes, the biggest killers of battery I've noticed have been push notifications and wifi. Turning both of them off almost doubled my battery life. I now have my emails synched every 10 or 15 minutes instead.

In addition to wifi and push, a big one maybe the biggest, which is often overlooked, is screen brightness. These big giant screens burn a lot of battery. Keeping it as dim as you can stand it will actually save quite a fair share of battery

heres a funny thing i found, i replaced my Apacer 8GB Class 4 card with a Sony 8GB class 4 card. the phone use to hang with the apacer card.

Calibrating Android's battery read will allow Android to fully charge your battery, and if you have battery profiles in setcpu, then the app will scale your processor speed by a more accurate reading, giving you longer battery life. I did it on the couple of builds I use most, and it really does make a difference
And dont feel silly john, I sometimes take my enormous screen for granted too
Edit: hmmm maybe my class 2 is why i get good battery life, maybe a slower r/w speed sucks less juice?

well, i know all of the normal tricks.. like screen brightness, wifi off, email push...
i am just looking for a windows rom, a radio, and an android rom, to get the best battery life...
thanks again guys.

Have a look at my signature.
Data enabled, push every hour only 5mA in standby.
If it is in airplane mode it only uses 2mA most of the time. That's quiet good

From what I can tell, the single most important factor for better battery life is using an auto boot app, such as Exceller's, to boot into Android soon as possible. I set mine to auto boot in 3sec. If you let WM/Sense boot fully, you will experience higher than normal battery drain; around 60-70 mA drain in standby. Also, try installing Advanced Configuration Tool in WM and enable all options under Power Management. Have tried these techniques with pretty much every WM Rom and Android combo and average around 3-9 mA draw in standby with wifi, sync, gps and data all enabled. This translates to about a day and a half of moderate use for me. Also, remember that Sense builds tend to use slightly more battery than non-sense builds.

This method really works! The simplest way!

It doesn't really, mV is a measure of state (what condition your battery is in), mA is a measure of change (how much power is currently leaving/entering your battery).
Download current widget, free from market, to track the current (= in mA)

Current Widget. Set it to update every 60 secs, and then leave your screen off for more than 60 secs, turn the screen back on, and check the widget.
Battery drain with screen off should be somewhere between 5-9 mA

Nice tips here guys...
My battery meter in the status bar looks about 60-70% full, but battery widgets say i have about 50%.
Does this mean that I need to calibrate?
I tried to delete the battery stats with Droid Explorer but it seems to be in read only? (It doesnt do anything when i click delete).
I guess I'll set up ADB and delete that way.
Also I seem to get better battery without LED me know, (why do i need this?)

Just run terminal emulator on your phone and type:

oh, you can do this on the phone.
Thanks bro!
I hope to see improvements as my theory that the status bar battery reading vs widget battery reading being so different = it needs calibration.

I am now using Exceller's auto boot, and the my draw peaks are waaay lower, but the idle has gone up! (60-80 now...)

so how do people get 3-5 ma battery drain?
mine always shows around 60ma and around 300 in home screen.
does that depend on the build or the apps installed and settings?
i cant figure out

It depends on all kinds of things. You do know you will only get a low current draw with the screen off right? Here are some things you might like to consider for longer battery life...
1. GPS on all the time?
2. Wifi on all the time?
3. Email sync frequency?
4. Screen brightness setting?
5. Install SET Cpu and create a profile for 'screen off' and set it to just above the minimum
6. Leaving processes and Apps running in the background
7. Time of day ;p
8. Number of widgets
9. Live wallpaper
10. Other stuff I haven't listed.

Usually it works after some resets and sometimes using another build can work. But if you've never had a low drain you might wanna try an other sd card. Borrow one from a friend and see if t that fixes anything.

yes thats what im looking at is standby drain of 60ma with screen off.
i have a regular wallpapaper some low res pattern.
wifi off, gps on 3g on

i make sure the keypad lights are on before clicking haret and i get <10ma standby on the first boot every time

I had the same problem, constant drain of 60-80ma even in airplane mode. I flashed to different radio and now i get 5-9ma all the time, how you boot or what you do in win-mo doesn't mater some builds just work with a specific radio. I use 2.14.50.04 for my t-mobile HD2, works great with desire builds.

Guys, can anyone tell me what does "ma" mean? And how to check it on the phone?
Thanks

It stands for milliamp hours and install 'current widget' from the Market to check it. Once installed, turn your screen off, leave for at least two minutes and then the widget will tell you.
PS lower is better.

After doing some research, I figured it out

Never thought "ma" is "mA"
Thank you so much

how does a phone go from 70ma to 6-7ma standby consumption overnight?
today my battery was at 90% after 8 hours.
yesterday it was at 46% after similar standby time

I haven't used setcpu in ages and I still get 4/5 ma in standby. It's kernel dependant, not cpu dependant. the ONLY thing SetCPU is good for now is overclocking for pointless benchmarks.

Could be you were having reception issues the night you were having high drain and it was searching for signal a lot, or if you have it switching to a roaming service. Had it happen to me a few times.
