idle process ->80%

I have been having a terrible time with battery of my hd.
I tried several rom, dutty,miri,lost in asia,engery, and last one was black pearl.
With every rom, there was one or the other problem, so had to shift to new one.
My only concern of any rom,was that it should provide a good battery life.
Currently with black pearl, the batter drains like anything.
I dnt have much apps installed or running.
Apps:
PocketShield (running)
Advance Cconfiguration
Touch in call
Advance system task bar
I checked the cpu usage and wanted to figure out, why the battery drains so fast.
The phone is in suspend mode.(wifi,3g,dataconnection, BT, AS,...everything is disable).
Still it will loose like 30% battery in almost 10hrs.
The cpu usage shows,
Idle 81.40
taskmgr 18.40
the above two kinda stays constant,
but the below processes jumps with cpu usage, frequently.
Asynckiller0.10
shell32 2.21
qwertmememory0.10
Can anyone explain me, wat this process are doing and is the idle process being so high normal.
If not what can I do to resolve this.
I did search the forum, but I found something to clear RAM, not sure, if that is the solution.
any help will be highly appreciated.

I am using Dutty's 3.9 at the moment and very happy about it I love it
It is fast and after soft rest only 34% memory is in use
Phone is always on internet checking email every 2 hour, regular talk and text and of course iGO8
It goes for me about 1 and half day
Idle 79
taskmgr 20
And only tmail.exe is keep in changing but always less than 0.20
Some of process doesn’t use any CPU usage unless one or more events occur like you touch screen or even changing signal bar

about the idle process, it's normal that it shows such a high cpu usage. dont ask me why but this is how windows monitors cpu inactivity. for example on your windows PC try to launch task manager and you will see there is a similar process, called System Idle Process, that uses all the cpu power that's needed to reach 100%. (EG ffox.exe uses 2%, explorer.exe 3%, system idle will use 95%.)
it does not mean your cpu is always used 100%, it means your cpu is 80% (or whatever) idle.

My experience with the battery life problems is this: Radio ROM matters most.
Also I must admit that nueDynamicClock (version 1.0 not the latest version) helps a lot.
Currently my battery lasts for 2 days if I do not use wifi a lot, and if I do not play NFS for hours.
I am currently using onkologs Super Lite 6.5 ROM with radio ROM 1.13.25.24, and I have the following Processor (nueDynamicClock) settings:
-default speed: 528 MHz
-after system is idle for 5000 ms: 122.88 MHz
-on backlight off: 122.88 MHz
-on suspend: 19.20 MHz
I hope this helps...

Idle means how much of the cpu is not being used, so you want that as high as possible and 80% sounds normal. That means that 20% of the cpu is needed to run the taskmanager and there is 80% idle (not doing anything). It's there so that in case you want to know how much of your cpu is not being used, you can simply look at that, instead of having to have to add up all the processes that are using the cpu.

SetCPU Gingerbread

Is anyone using SetCPU with gingerbread?
I'm using GingerVillain 1.5 but I can't seem to find the right profiles with SetCPU.
Oc'd @ 1,2 Ghz without profiles.
Because when I use the screen off profile, my screen sometimes won't turn on.
Screen off - min 245 max 1200
Can someone help me finding the right profiles?
Share your user experience.

In my experience and many others too, the profiles are not needed. The only profile you should ever need is a temperature profile and that's only if you really have it cranked up.
Having a screen off profile is always bad since switching to another profile doesn't happen instantly - there are polling intervals involved and until the next cycle runs your phone will still be using the screen off profile. That makes the phone slow which causes SetCPU to take longer in switching profiles, bogs down the cpu and it becomes a vicious cycle for a few seconds (sometimes a couple minutes). All the while it's draing your battery because the cpu has to work harder. Even regular profiles eat the battery due to the constant querying of the systems status and processing power used for that - which is the main reason you'll hear people whining about their battery life (some aren't effected as much).
Profiles are just not a good idea except for a temp profile for those that oc to the higher GHz (probably 1.4+).

You could try using cpu tuner instead. Gives you way more options.
CM 7

You have a lot of options with cpu tuner.
What triggers and/or profiles do you use?

My screen on/off has been working fine with CM7 nightlies before and after the RC1. I've been using SetCPU with a normal profile of 1017max/245min and a screen off profile of 365max/245min.
I think your issue is with overclocking. Idk about Gingervillain but as far as CM7 goes lots of people are having issues with the on/off animations and wakelock issues when overclocked over 1ghz. Try using your profiles and clocking at or under 1ghz and see how things change.
Not sure why anyone would really need a higher clock than 1ghz but what do I know. I dont see any slowdowns at 1017mhz and I feel that anything faster than that would lead to heat or battery issues?

Yes, screen off profiles work. But they drain your battery faster than if you have no profiles.

thanks bro, i OC'd to 1017 and there are no issues

I'm not so sure about this. Have you tested this at all? Starting using screen off profiles of 365max/245min have really increased my battery life, especially when my phone sits idle for a decent amount of time. I don't think you could see more battery life by leaving the clock at 1ghz while the screen is off.

Every kernel that I know of out there drops down the clock cycle when the screen times out. The reason not having the screen off profile saves the battery is because SetCPU isn't constantly sending requests about the phones state and then checking that against your profiles to see if it meets the parameters set in them.
Now it could be a bit different for you. You might have a different set up or different apps that make having a screen off profile useful (ones that constantly update or run in some way). You just have to watch your phone for a few days and get an app that keeps track of that stuff so you know which route to take.

This is very true. It is definitely hard to make a blanket statement because no two people have the exact same setup. All I was saying is what I've been doin with the screen off animation and I've been having pretty solid battery numbers.

Constantly awake

Hi guys,
My phone is constantly "awake" despite rarely even turning on the screen.
Would you know what could be causing this?
I'm currently running Caulkins rom and whatever kernel it came with.
My battery life is ~15 hours so I dont think it's affecting my battery too much.
Either way, is there an app that can tell me whats causing the drain?

First of all, to see if your CPU is sleeping properly when the screen is off, download CPU spy… it is an app that gives you total time the CPU has spent in each scaling frequency available.
Then download watchdog, this app tells you which programs are polling the CPU for usage.
Then download “better battery stats”.. this app tells you if there are wakelocks.
With those 3 apps running at the same time, you will find out any abnormalities in your system caused by applications.
Side note – disregard info that either of the apps report about each other (obviously)

Battery life stats and questions

What's a good figure for battery life on the GS3? The best I've got is about 31 hours using on demand and bfq. Any one got better life using other settings? I heard someone getting about 43 hours life but that seemed to be a little unbelievable. Let me know what your getting
Sent from my SAMSUNG-SGH-I747 using xda app-developers app

What you reported is definitely "the average". Most actually only get a day, if they're lucky of moderate use and have to plug in before sleep every evening and get going on charge in morning. So its more like 15 hours actually. And your 31 max is very common high end for people who've stretched it out.
I'm not sure if you're stock rom or not and if rooted either but that makes a big difference.
I'm rooted ( and would ALWAYS RECOMMEND ROOT FOR EVERYONE EVEN UF NOT FLASHING ANY ROMS AND STAYING ON STOCK. The ability to have full control is important.
Changing kernels and more importantly, undervolting, will give you that longer life you're looking for.
I'm currently on KyanROM with either Ktoonez or Faux kernel (heavily tweaking and testing both) and have this phone beautifully undervolted to exceptionally low and very stable mv numbers! Thus getting me that lovely 36-45hour average (you mentioned you saw posted elsewhere - yes it is possible and many are doing it). I basically only need to plug in every OTHER EVENING or night between 6pm and midnight depending on usage and I'm a moderate to heavy user (with a lovely 3-5 hours of screen time as well) AND I also have my phone overclocked to 1.8Ghz! Surprisingly, the oc doesn't make much battery life impact at all because the phone isn't constantly having to run at high levels, only in short spurts. Actually, due to rooting and kernel change I'm able to have my phone run as low as 192Mhz during much of its general activity and deep sleep ( which I get a ton of as my phone basically always goes into it when the screen goes off). This saves me A LOT of battery life.
I also use LTE, which is actually one of the biggest if not the largest battery hog, next to screen time of course. But with that being said I only use it when needed and have it turned off when not in use.
As for my peak I was able to squeeeeeze out 87 hours once, on my stock battery BUT that was with some abnormal(for me) measures that really help conservation. Ie, no LTE, under clocked to 1.2Ghz for good part of the three days, much less then normal screen time over the period of which I used it at lowest level with even further reduction via screen filter, I actually used airplane mode during my three overnight sleeps (which I seldom use but if you can hack it, do it! It can really save battery overnight. My current setup basically SIPS MY BATTERY AT 1% EVERY 3.5-4 HOURS OVERNIGHT WHEN IN AIRPLANE MODE), mobile data was off for most of time but did use my wifi at normal level (wifi uses less especially if good signal with few reconnects/scans), used my typical low UV numbers, kept my notification updates/syncs/wakelocks to a minimum and lastly kept my memory virtually clear if unnecessary background apps.
Doing ALL of this allowed me to get OVER THREE DAYS BATTERY LIFE. But keep in mind I seldom do many of these battery saving tips on a regular basis but some do and if you can, they WILL work to extend your life substantially!
To wrap up (this long winded post/reply) I'll give you my general UV mv range numbers and the typical everyday simple battery saving methods I use.
1.My voltage at lowest clock of 192mhz=800mv with gradual (smooth and almost linear curve) increase up to a mere 1200mv at a whopping 1.890Ghz clock.
I use NOOP scheduler with ONDEMAND governor most of the time, sometimes SmartassV2.
My screen off and deep sleep use this lowest 192 clock speed and with no wakeup lag.
2. I use my screen at 0% brightness most of the time (except when outside or in high lighting environment). I use the brighrness widget app to control this as it is easier and works better then stock settings. I actually even further reduce my brightness with Scree Filter App. That app is awesome and often use it solely for brightness control because it has full control and can dim it to basically full black if wanted. Which is MUXH lower then stock control. Fyi I use my phone a LOT more at night or in dark environment thus allowing me to dim screen HEAVILY yet it still is actually plenty bright with ample contrast in dark environments to do everything. This saves on my battery HUGE!
3. I use LTE when needed and GSM/HSPA+ when not. Seldom turn of mobile data altogether. I do turn off wifi when out and only using mobile data.
4. I use Screebl app to have screen turn off when not in use. Its great liitle app. Basically let's you turn down screen timeout to 15 seconds or less so screen is never unnecessarily on but it always stays on when in use due to the accelerometer and it knows when the screen is not flat on table! Its very annoying when browsing or doing stuff where screen isn't touched for long periods and the screen goes to sleep! But this stops that! So its always on when upright or in use and when phone down it turns off immediately.
5. Very important step and can take some time and research but making sure to keep partial wakelocks and apps keeping device awake to a bare minimum! DEEP SLEEP IS VERY IMPORTANT TO SAVE BATTERY! You basically want it to go into that every time your screen goes off and to stay in it uninterrupted for as long as possible. And many users phones are NOT making it into deep sleep due to partial wakelocks and they don't even know it or how to fix it. Not getting deep sleep can unnecessarily kill your battery!
I use a few tools here: Better Battery Stats/GSAM Battery Monitor/Battery Monitor Widget from within System Tuner Pro (which is my also my main and highly recommended tuner app for CPU oc/uc and UV,etc.).
These apps really help to determine what, if any, apps are causing partial wakelocks ( displaying in wake number amounts and overall wake time) allowing you to determine what to do to fix the problem and let the phone gets as much battery saving deep sleep as possible.
6.I'm not big on auto app killers and actually recommend against them as Android ICS does this already very effectively but do keep in mind that the more active background memory that is used, the more battery the battery is drained. So I personally kill unnecessary apps myself from the background whenever possible to save a little battery here and there. Using the apps listed above in #5 can really help to detect a nasty background app or service that is quite possibly unknowingly using a ton of CPU and/or memory, thus draining more battery and also often just slowing down your phone!
7. For those who can use it Airplane Mode is a big saver! Try overnights if wanted as long as missing notifications, emails, calls, updates, etc is alright for you. I seldom use it but it does help.
8. I almost never use my Bluetooth and GPS but when I do that is the ONLY time they are on. They get turned off immediately and really be careful with the GPS in particular because you might be surprised how many things on your phone will use it in the background, sucking your battery!
9. Be careful with sound and vibration levels. Haptic feedback too. I don't do much here but its anotherctip nonetheless.
10. Lastly is treating and charging your battery right! I found an amazing site linked down below in a couple of articles that really explains these batteries and how they work in a very in depth technical level this is still not too hard to follow. Aside from the two links I posted check out the others on the left menu as there is a ton of useful and educational info!

http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
OK I've rambled on waaay too long here. Maybe I'll take this and post a battery savings tips thread with it lol. "10 points"!
Btw I've just received both my 3300mAh and 4400mAh capacity batteries. So I have much testing to do on those too and I plan on reporting back on them as well. Also with screenshots for data and proof...I can and will also post screenshots for all of the numbers and stats I've posted here today with my personal phone/battery accomplishments.
Hope this helps some of you out there because yes this phone can be known for terrible battery life but it CAN be tweaked to SUBSTANTIALLY IMPROVE that life to high standards and keep up with the best of them!

On Stock battery - Kyan Rom/Ktoonez kernel (at this moment)

Seems about right. My phone is completely stock and if I really wanted to I could even use it for 2 work days. I usually charge it over night though. I used it for 2 days though while at work, and with 3 hours of screen on time I was down to 7% battery. Around 40 hours on.

I was stocked rooted using Sammy kernel. On demand BFQ. I'll try on demand noop and see if that helps. My screen was about 35% brightness.

Can I hijack a little here? My battery seems to be atrocious. It was okay stock after my first 3 full charges I was getting about 12 hours and 2.5 screen time.
Here is what I've done with my phone since:
Flashed to debloated stock Rom
disabled remaining unneeded apps (example ATT wifi app)
disabled Wifi
disabled bluetooth
disabled GPS
disabled GPS autorun states
disabled 4g
disabled autobrightness, set to 15%
disabled location reporting
disabled Push email with Exchange
disabled Motion
disabled auto google backup
disabled keytones and vibrate on all button presses
disabled touch key lights
disabled Svoice
disabled streaming on googleplay, only plays from memory card
disabled Google Now
fixed the cell standby bug (even though it may not impact battery figured wth)
Uninstalled FB
Set all Autosync accounts and email to sync only once per day
No widgets (only Google play music, Smemo note, flashlight, and folders)
Running save power mode for low power screen, no haptic, and auto adjust screen to blacks
Running mostly black wallpaper, No live wallpaper.
Running medium intensity vibration
I ran battery stats and got a lot of wakelocks from googlemaps and exchange so I disabled the push email and set it to once a day. Google maps I disabled latitude, and shut down the autostarts with gemini.
It's getting to the point where the phone is basically a dumbphone just so the battery can make it while it sits next to me at work. Today I have 48% after 8 hours and 50 minute screen time and 20 minutes of google play (only playing from on SD card not streaming).
Any ideas? It seems like I'm getting less than average.

All I did was also flash debloated rooted stock. Set to top out at 1.5ghz power save on. On demand BFQ schedule. Screen brightness as low as I can to still read. And got 32ish hours. I'm going to try OnDemand and noop like the other guy said and UV a lot more and see how close to 40 hours I can get

Can u link me on the bfq? Having troublefinding what that is.
Also, is that the built in power save that limits the processor or some other software?

I believe if you flash Sammy kernel it has bfq. I am on task's CM10 and kernel and battery life seems poor compared to CM9 or stock rooted

[Q] What exactly does battery saver mode do?

All I can find are vague descriptions. Nothing saying what exactly it's doing. From my experience thus far it's doing nothing. I am not getting better battery.

From what I know it lowers the CPU clock speed and decreases brightness. All with the intent of saving battery.

I read that while it DOESN'T limit the CPU, it does lower the brightness and cuts out your data/BT/location/NFC in order to preserve the little bit of battery.
Edit: And syncs.

I don't think it actually does any of that though. I have been using it a lot the past few days half on half off. I still get all MMS and emails right away plus my photos are syncing with google. My brightness doesn't change (auto or not). plus I have BT and WIFI on all the time for smart watch and of course data usage . Maybe the processor, but im not even sure of that. Guess I could do benchmarks with it on and off and see. I just feel like this feature is doing nothing at this time. On my nexus 5 I could really see the processor throttle and brightness him with battery saver.

Mine only does that under 15% battery. Seems like its doing nothing over that.
Sent from my LG-H815 using Tapatalk

The default is under 15% and when it kicks in, i definitely notice a difference in the phone.
You can change it to immediately from 15% and i bet you will notice a difference at any battery percentage.

Cpu speed is not affected, just checked this.
Brightness was indeed cut off considerably, haven't checked for other things yet :good:

I figured out why it wasn't working for me. Simply clicking the icon to green in the pull down only enables it when it gets before 15 percent. Didn't force it on now like I thought it was.

Why is there so little discussion on this feature? I found very few threads on this and this was the most active conversation even though it is so old. I found out today I could enable this feature at anytime, not just at 5 or 15%. So I have it enabled at 100% battery and testing today. Upon enabling battery saver mode and restrict idle apps, the screen immediately went dim. I turned it back up slightly. I also noticed apps acting different. Toggling between apps is quicker and the animations are gone. Also, I'm using chrome and it's acting different. It's hard to explain, but if I'm navigating from one website to another, it is feels like it is refreshing every time, it doesnt feel faster. Im not sure what it is doing but someone with more experience will probably be able to pinpoint exactly what is happening. It's not standard chrome behavior.

Not sure with the Chrome part of it. I use a different browser. With FireFox everything feels about the same as before.
I also noticed the animations are removed so there is no fancy domino effect or sliding going on. It's all instant and to be honest it feels heck of a lot quicker this way.
Screen is much more dim and is extremely conservative for the most part.
Clock speed is the same. Although I wonder if there is some sort of under the hood change such as MPDecision switching over to battery saving mode. It personally makes no sense to leave it as is considering in the past it use to cap the clock speed.

So using battery saver today along with restrict apps in background, the former definitely shuts down background data. I noticed Google play store not authenticating paid for apps. I had to go to the play store to launch the app and re-authenticate. That is where I received the warning that background data is off. I have a weather widget and that does not appear to be updating as that uses background data. I have a barometer widget and that does appear to be working as that uses sensor data. All that is required to re-enable background data is to uncheck restrict background apps under the battery saver mode. As of right now, I am at 71% battery and 2 hours 14 minutes screen on time, 3 hrs 53 minutes on the battery. I'm mostly using chrome while screen is on and podkicker and listened to about an hour of audio and a little bit of teamspeak usage with my Bluetooth headset. Brightness is at 37% which is pretty dim in this mode. I'd say it's equal to 15% in regular mode bit good enough to see.

Update, I went all the way to 25% battery remaining yesterday and I had right at 5 hour SOT. In my opinion, this mode is not worth the hassle. Background data is off and that breaks a few things. Screen is pretty dim and I ended up turning it up anyway. I have had similar battery life in the past anyway. I have had 7 hours 20 minutes of SOT before without this mode on and all my widgets working. I'm going to leave this mode off.

It saves battery
