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.

Battery Life Vogue Android

So, I recently got a vogue and immediately put android cupcake on it. (great work devs btw )
So here's the problem, I cant get through the day 7 am - 12 am with light to moderate use without needing to charge.
I would like to keep 3g/background data on during this time.
Has anyone had any success having their vogue-androids last this long?
Are there any advanced power managers that allow you to change the backlight quickly and easily or allow you to turn data off during certain times? (like data off for a 1/2 hour and then data on for 1/2 hour)
Thanks,
Kevin

There's an app called "Locale" which is apparently awesome, but I haven't tried it myself. It changes settings based on your GPS location, but I'm not too sure about time of day. You may want to check that out.
As for the battery lasting that long, I dunno... I don't think I'd fall into the "light usage" category. My battery typically lasts from about 7:30am till 9 or 10pm though... I'm not too sure, I usually plug it in when I get home from work around 6.

That would need more battery, since it would need GPS.
We don't have network-based GPS yet.

I have had the same problems with battery life on my vogue even with light usage. Also I don't believe CDMA has the same issues with 3g causing higher battery usage like gsm does. I have tried widgets to quickly toggle the backlight and gps function but only saw minimal improvement. Not sure if the increased battery usage is just a fact of android or if there remain porting/performance issues still to blame.

i've got my background data set to off and i keep gps and stuff off unless i need it and i've got my email set to update every hour and i found this actually gives me better battery life than when running windows so i just went and bought an extended battery off ebay and hopefully it'll get through a complete workday(10 hrs) where as right now i'm getting between 6 and 8 depending on how much I use it.

My battery used to drain pretty rapidly.. 7am - 2pm... but now it lasts from about 7am - 6pm. I think theres a certain amount that the battery can condition itself. I've tried discharging and charging and I do believe that its helped.
Do you guys notice that battery readings are not accurate though? Apparently it has something to do with the temp. sensor in the battery not being correctly configured. For example, if my battery is at 20% and I plug it in the charge, it'll jump to 40% in a matter of 10 mins.

i too am having pretty bad battery life even when i don't use my phone. why would the battery drain so fast when its sleeping? would that togga app help at all with the latest cupcake build?

Togga has been replaced in Cupcake by Modem. They do the same thing, essentially. If you want to turn off your data connection, open Modem and click Disconnect.
Also, in your default.txt make sure the pm.sleep_mode setting is set to 0 for best power saving.
Lastly, update all your files to the latest. The newest rootfs.img is supposed to bring more power-saving functionality. I just installed it this morning, so I can't comment on it yet.

yeah i just updated all of my files, ill check my text though.

i checked my text and it is set to 0 already! not a good thing when it only takes 5 hours to drain 50% of my battery life. i hope this can be fixed in future builds, i may have to go back to winmo for the time being because i need my phone for work.
i really love android though!

Do you have "Use Background Data" unchecked under Settings > Data synchronization? This makes a huge difference. If you have unchecked already, I don't know what to tell you.

with the previous rootfs (just before the new one today 2009-08-04) I've been getting 10 hours with moderate usage, backround data enabled, contacts and gmail auto syncing and locale set to turn my ringer off based on location (btw, I do beleive we have agps working now). Upgrading to the newest kernel and rootfs with more improvement to see if I can get a full day as I am awefully close now.
oh, and I also have a weather widget updating every hour, pretty good battery imo.
EDIT: Tip for battery life, I have my default screen brightness set pretty low, about 30%, as this is fine for most indoor conditions. I use an app called fastbright placed conveniently on my home screen to immediately turn my screen to 100% with the click of an icon when I am outdoors. I also use locale to turn the screen all the way down to 10% when the battery is less than 10%. Both are recommended apps.

I think I was getting much better battery life before introduction of rootfs, like on the order of 4-5 hours more (running hero themed ion). Anyone else have this experience, or is it just me?

Actually yeah, I tried the latest initrd and rootfs today, but it seems like it's a bit lower than it usually is this time of day. I think the first implementation of rootfs was better than this latest over the non-rootfs versions, though. Maybe I just used it more. I kept all the same settings and usage for the day was typical.

Best option is to buy the Extended Battery from DealExtreme for $8.. search for HTC Touch S1 .. the back cover doesn't fit properly but you can always get a one that fits from ebay..
this battery lasts me thru out the day even with heavy usage.. and for $8 u can't go wrong

Today I didn't touch my phone for the first 4-5 hours of my day after charging overnight, and was down to sixty-something percent. I know that on older initrds I was doing much better than this, at least 80% at noon with no usage.
I'm wondering if optimizing memory with the new rootfs stuff has been a trade-off to poorer battery life. Since I'm using mssmison's hero themed ion which is screaming fast, I haven't noticed a difference with the root stuff and think I'm going to try switching back.
I'm switching back to the 7-30-09 initrd.gz, because that's the last one I know my battery was doing much better with and will post back after running it tomorrow.

My issue with battery life is that my phone doesn't seem to know how much battery it has left. It will be on 60 percent, I'll plug it in and 5 minutes later its fully charged.
Or after it comes off the charger overnight, it will go down to 60-50 almost immediately but stay there all day while at work with light usage. I also hate that it doesn't know when its full, I hate to overcharge the batter. So many opinions on if it damages it or not.

battery drain whad exactly to do?

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
email sync every 30 min
im not really sure what counts as widgets(google search bar power panel?)

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.

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.

Prolong time between charging

Hello!
Today my battery on my Epic 4G with Froyo drained after 12 hours. And actually, I didn't do anything. I'm still new in the Android. Can you share your best practice what you are doing to prolong time between charging? What apps you are using, what you are turning off, etc.?
Thank you!

First step is to install Spare parts and figure out what is in fact draining your battery. You need to check if its running instead of sleeping when the display is off. Also check in settings under About Phone > Battery Use to see what is using the most battery.

The biggest thing I did to help my battery was killing the drm process. Also when your phone reboots put it in airplane mode for a couple seconds so your time without signal won't be 50% and killing your battery. And if you use wifi change the sleep to never. Other things I leave gps and Bluetooth off till I need them and I keep the brightness setting all the way down and I don't use live wallpaper.

I've checked the Spare Parts. 98% of running time is process called kswapd0. I don't know what is it.
What do I need to do to prevent it?

[SOLUTION] Found a fix for battery draining

This doesn't work. Ignore this thread please. Android OS and Wi-Fi Sharing reappeared after a few hours even though I was in bed sleeping and not using the phone.
For those who have problem with Android OS and Wi-Fi Sharing draining battery, this is for you.
I think I have found a solution. I need someone to try it out with me. So far so good. The main culprit is Kies Air. If you are not going to use it, please do not tap on that app at all. If you can, hide it. Once you tap it, it will remain running forever even if you shutdown and restart your phone. So what can we do?
First, Factory Reset the phone. Then, make sure you do not launch Kies Air after Factory Reset.
That's all. Now all you need to do is monitor the battery graph and let us all know your findings. You should not see Android OS, Android System high up in the list. Wi-Fi Sharing will no longer appear in the list that consumes battery.
I have success with this.

How long have you had it running like this?

why dont you just end the service in the settings?

I use Kies Air extensively. But it does not really keep running in the background here.
I dont keep my wifi on unless and until needed. SGS2 is very quick to get IP than my older phones, so i turn it on when needed from widget. Also you dont need wifi on before launching Kies Air. It will turn it on and off by itself.
when i close kies, it asks me if I want to disable wifi and it closes properly.
I tab of ATK and it closes on me never to turn back on by itself.
The only programs that keeps coming back are hubs and iplayer which to be honest does not seem to eat juice much. I will be getting rid of them soon enough.

now that i think of it the nexus one doesnt have kies air does it ? and it has the same android os issue?

Kies air shutdown wont help, did not even have it installed and still have android os bug

I've had both android os and wifi sharing eating battery, and I've never touched Kies. So it's not that.

not a soluton for me.. becuase i do occasionally use the wifi sharing so that i can tether over wifi.. the solution i am using which is kinda kludgy is to freeze the two wifi sharing apps with titanium backup (requires root).. works for me.. when i want to tether i will unfreeze them.. hopefully this will fix in a firmware update.

sorry guys I am late to the party.
WHAT AM I SUPPOSED to see for "Android OS" and "Android System"?
My phone right now is at 4 h 15 min (I charged it before going to bed, yes I sleep 4 hours a day). The phone did not do anything, but sounded Alarm to wake me up, and I had screen on for like 10 minutes total so far, plus the Alarm sounding and vibrating.
I have AOS at 37% up top, and AS at 3% on the bottom. This is not right?
I used Kies many times, but restarted the phone after the last time, and that was before the phone was charged last time.

my AOS is at 6% now - it was at 47% this morning... but i think that was because the screen was 0% whilst i was alseep, so yes your 37% is waaaay too high, mine was up at 15% but since i installed juice defender it has dropped to between 6-8%

Android OS / Android System percentages don't really matter that much - even if the device had a week long battery life, the percentages still have to add up to 100% - so something always has to be using battery.
The main problem seems to be the 'wifi sharing' and 'wifi sharing manager' services, which start up whenever you connect to wifi...

You mean you're connected to Kies Air and wanted to play with your phone while waiting for files being transfer? The answer is yes, press the home button and do whatever you want, it will not be disconnected.

Sorry, I meant when I finished and exit the program, something continues to run in the background (wifi share?) that drains the battery?

Damn...
Android OS @ 46% followed by Display at 21%. Android system however, at just 4%. Yeah 46 is just way too high...

Oh.. my watchdog didn't report any app misbehave after I done with Kies Air.
My wifi sharing will keep on running on background at 3% regardless of whether I connected to Kies or not. Frozen it but it still there. LOL. Weird.
