Froyo/Sense Low Battery Life Investigation : android.process.acore task

Hello everybody !
A few people seem to complain about low battery life with Froyo/Sense roms. As I may have a little clue about the origin of the problem, I felt like opening a new topic.
Seems like the task android.process.acore is stuck at 100% CPU for some of us.
Rom Used : LeeDroid v1.8, with latest radio

Any idea about the origin of this problem ?
Thanks for your help

is it a cpu percentage in a last column?
so there are 100%+6%+7% at the same moment?

a google search brings this thread up
http://forum.androidcentral.com/htc-evo-4g/19040-android-process-acore.html
check your contacts sync - is it constantly syncing?

Doesn't look like. Disabled contact syncing and it doesn't change anything

That figure does not mean 100% CPU taken up with that process, it means 100% of the 19%. Your cpu is not running at 100%.

You have LauncherPro doing something weird there?

try going into testing mode ie dial *#*#4636#*#*
select battery history
change top line to cpu usage,
I have the following
android system total time 5secs
android.process.acore total time 4secs
htc sense 2secs
etc

or download spare parts from market

The screenshot is from my phone.
It is running LeeDroid 1.7a with Launcher Pro Plus v0.7.4.0.
They stay at 100% when the CPU load is not 100%.
They both have the package: com.fede.launcher.
So is LauncherPro doing something wrong or not?

kill launcher pro and see what happens. Its not a rom issue - i do not use launcher pro and have no issues.

i have also this 2 at 100%, what are anyway?
yes they're com.fede.launcher.

I just restarted LauncherPro from its own menu and this made it go back to 0.

Same for me, cpu load went back to 0 when I killed LauncherPro.
I'm gonna play with the rom a little now to see how battery goes.

What kind of program do you use for see process work??
Is System quick info?
Thanks soo much

Android System Info

I have exactly the same problem with my Samsung Galaxy S (Firmware I9000XWJM2, Root, ext4 Speedfix)
I also use Android System Info and my screen shot would exactly look like the screen shots posted above.
I noticed a somehow slow behaviour of the device, this started a few days ago. Restarting Launcher Pro doesn't really help. After 5 minutes the two Launcher Pro tasks are back with 100% cpu load. The overall cpu load ist between 20 and 30%.

I have 2 at 100% also but load is between 7 & 27%

Rename Thread
Can some admin please rename this thread.
I don't believe it's a froyo/sense issue because i'm using
a Samsung ROM on my Galaxy S (eclair, TouchWIZ), it's not a custom rom.
Does anybody have a solution for this problem?? It started a few days ago.

[HELP] Battery Use App has gone mad!?!

Hi folks!
I tried to search the topic before starting a new thread but I couldn't find any.
So, here's my problem. I noticed that since I flashed the stock JQ1 Gingerbread from chainfire's thread apart from everything else being fantastic, the battery use statistics in Settings -> Status -> Battery Use I can see are stranger and stranger.
First I have noticed that my the battery usage of Display had frozen to 2%. It is completely impossible, comparing it to the Froyo before, where it often went beyond 50 or even 60% of total battery usage.
Then, I saw that the Android System was taking about 90% of the stats. At first I thought it may be the infamous Gingerbread battery drain. It is not that, however, because I do not feel the battery draining any faster than before.
Then came the realization that no matter what application I am running, it does not get reflected in the Battery Use - only Android System percentage grows bigger. The funny part is that from time to time the total of all percentage goes beyond 100%
And, finally, today I unchecked the background update of the PULSE application, because I do not really use it and checking the Battery Use again what did I see. See attachment:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Not only the display category had gone away totally, but half of the battery usage is now transferred to PULSE, which I don't use.
Please, do you have any ideas how to repair that?
I am on a European Galaxy Tab, JQ1 2.3.3 Android + CF-Root v3.3 for JQ1

Not anyone experiencing the same problem? Just a little update from me. I read half the cloud already, strange but it is the first time that I cannot really find my topic in Google.
I tried what not - no result. I wiped battery stats, which only helped to the extent that the PULSE has gone from battery use stats, and display is back but the readings are stuck at 2% no matter how much I am actually using the display.
I read somewhere that it could be the kernel, where some thing may have not been allowed or switched on??? But if that was the case I would not be the only one with the same problem, but all the people that have flashed the ROM + CF Root 3.3 from chainfire's thread????
Still no ideas?

Hey guy,
Once ago I had the same problem. I don't think that pulse realy eats your battery. But we all know that the battery statistics is incorrect. So don't worry. Do use "AntTek App Manager ☆ root" (its free) to remove the puls app and wipe the cach. Or just install the overcome rom. It's much better then the Sock Rom. Trust me Because after removing of puls, there are other false statuses. I don't remember but i think it will show you that the battery is eaten by the core apps for more then 70%.
Sorry guy... I know about my terrible english

Hey odysseus84,
don't worry about your English. I am glad that you tried to be helpful. It is not that bad. After all I understood what you mean. You are right, even without Pulse in battery stats, I am still missing statistics for practically everything.
It is interesting that the Battery Use fails to record third party apps. As you can see below, the usage for all main system processes like Idle, Standby, Bluetooth, Wi-fi, Voice Calls are there. The statistics for display usage is stuck at 2% as already mentioned, which is the most annoying part.
Another interesting thing is that everything seems to be put into Android System usage, because normally it wouldn't get more than 10% of the overall battery usage share.
May I ask for other people running Gingerbread 2.3.3 to post their battery stats here?

Look. It's just a Bug. There is "Android System"written but it means the % of the Display. There is "Display" written but it means something else. As you can see on the attached pic we have almost the same "Display" usage.
And the other thing is that the statistics nothing shows with less then 2% usage.
Finally you can just accept it or flash something else.

Is this happened after you root your device? I'm using the same version, but my android os is ranging 800-850mb usage. After I root my phone it feels, getting slower.
By the way I'm USING B103

Nope, actually I'm a newbie in terms of rooting.
After I root my device I'm currently observing it. Came across to this thread and share my situation as well, even my battery I'm keeping an eye for it. Had one problem where as before I go to sleep, the only app working while my phone is lock is my alarm clock, I set on smart plan and while sleeping my wifi is still on. Form 1:30am to 7:30am my battery starts in 66% and when I woke up its in 53%..
Having 800mb-900mb running in Android os usage Is alarming? Pls enlighten me. I think I messed up my phone because I rooted it..

Hi, as i am also a newbie, i am not sure i am able to help much. but I think it could be a rogue app that is causing the large battery drain on your phone.
after playing around for awhile, i discovered the issue for my phone lagging, which is caused by the notification app (Floatify). i have stopped the app and my phone is back to being speedy and fast. perhaps you can try to disable or stop some apps to see if it helps.

Where can I see this? Is this the one that you ask? Kindly see the attached link. http://imgur.com/1xzDWUS

Something is messing my battery up.

While using Twitter or any app, my battery goes down at least 4-5%. I can't get decent battery on this.
I have the Verizon edition.

After charging the phone i think in all editions you need to reboot in order to stop the battery drain try it and tell us. It is like a "bug " on current firmware

The bug i told you is from android system battery drain
twitter and also facebook are battery non friendly....
i personally deactivate facebook and twitter with package disabler pro when i dont use them.
post your android systems battery stats
you had 25 mine is between 15-18
is your phone band new ? if yes maybe you need to let the battery make some charging circles

It is pretty new. I didn't think that would effect anything. I guess I will let it have some cycles then.

I have some ideas that might be able to get the problem solved. I would first try turning off your phone for 5-10 minutes since it might be overheating. Then I would uninstall any new apps that you might have installed since you can remember the battery drain starting. There is a small chance you might be experiencing some battery drain issues from a third party app that caused a virus. Its also a good idea to get a security app like avg since its free. Other then that you might also want to check that your phone is not completely full on storage, and also consider turning off the facebook app since it can cause some serious battery drain issues as well. I think thats pretty much it if you want to get rid of facebook on your galaxy s7 here is how to do it. and it will really help with your battery life

I had the same kind of battery drain on my Sprint variant. A factory reset quickly fixed that issue for me.

So I used it up for a day and let it die completely. Charged it right back up and now its pretty bad today. These are screenshots from when I made it die.
I did disable Facebook. The Android System and Screen are using the most up right now. It went down about 7% for being almost idle. I used Twitter once.

Possible Solution to the DRAIN!
Ok, so I've had the same issues as you. My findings are as per Gsam Battery Monitor:
1. High Android OS and Android System usage~ 20-30%
2. High Phone Radio ~ 40% at times
3. Overnight drain of at least 4% (stanbby drain)
4. Screen usage 'while off' higher than 'while on'
This was frustrating and is as mentioned by other users to be a bug from updates and related to charging.
SOLUTION:
Today Gsam reports my Android OS and Android System usage and Phone Radio at 10% and below.
All i did was...
1. Let it drain to about 90% after charge.
2. Restart the phone.
3. Then plug in the micro USB to USB connector (the one that comes with the phone) with a flash drive attached and play a song/short video.
4. Unplug and enjoy great battery life.
This worked for me so it's worth a try. Will test a full charge soon and hopefully it doesn't require the steps above every time to stop the drain.
btw I'm NOT rooted, using LTE.........wifi,bluetooth, AOD and locations all off.

Horrible Battery Life 2h SOT - Need Kernel or other tweaks advice

Okay, so to make a long story short I have terrible battery life. (See image below)
I don't even game, all this time the only thing I did was listening to music trough my headphones whatsapp, and some low usage of Facebook (Messenger). Nothing special in my eyes.
2h55 min SOT. This is really the worst battery life I ever had on every phone, I have this for a couple of months now already. And I am so done with it.
I am looking for options:
Will a new kernel help me out? If so, which one? I don't like fine tweaking. Just a new kernel that works, no tweaking and that works for battery life. I heard FrancoKernel, or ElementalX is good. But keep in mind I just need a kernel for battery/performance. Not for fine tuning.
I will also install xXx No limits. Is this recommended for my case?
I want to know all of your opinions on this, and with my batttery life in mind. Because I really want to get this fixed, I am getting annoyed so much.. Thanks!

Yes, its a while ago now. I think it has been 1-2 months ago. But I can remember it didn't make a huge difference. The thing is, I can't reset it because of banking applications and working abroad. (I wont be able to install them again). And I am pretty sure it wont help.
So I am looking for a kernel option or other tweaks..

There's no miracle, a kernel won't help significantly. You just need to track what's draining your battery. Delete ad many apps as possible, deactivate system apps you don't need.

You can try deep clear in the recent apps management and turn off smart boost in the laboratory.

You might have to replace the battery if the other suggestions don't help

Download Accubattery from play store and charge your phone above 80% then check battery heath, i have 86% health and it's pretty good.

Also if you oem unlock bootloader it will wipe everything.

Your doing something wrong.
Tinder much? Or u checking to many IG babes?
Edit: in that case nothing wrong, but something else is wrong (logs plz)

I'm experiencing exactly the same. Idle battery drain is about 1,5% per hour, I hardly get more than 3 hrs of screen on time. I do think it has something to do with the OS, but can't figure out what...

Go in Google settings, location, scan, and check in wifi and Bluetooth are enabled. This combo drains a lot

Airplane mode + Wifi enable.
