[Q] Maybe a clue to battery issues? 2 instances android.process.acore using 100% CPU

Let me start by saying Thank You VERY much DroidTheory (and everyone who has contributed to making this an excellent stable ROM).
I am on the 1.4 (wiped cache, dalvik, battery stats, formatted system) build and I've been having the battery issues that everyone is talking about since 1.2. I am in the forums constantly and I have read all of the posts and the fixes for them. I have wiped battery data from a full charge, I'm on 1.4 so OMA files are already gone, I'm in Portland Or and we have stong 4G no drops ever since I have had my phone. So it isn't the cycling 4G/3G issue.
So I know there are multiple "my battery is dying" threads but I had not seen this one mentioned in any and don't want to get buried.
So I am having a bit of an issue getting a screen shot of it everytime I try I just get a wierd distorted image. That is not the issue I came for but if anyone knows.
What I am noticing is when I use the "Android System Info" app in the processes if I sort by CPU% I see 2 instances of the same thing "android.process.acore" both reporting 100% CPU and 35.28MB RAM. My total CPU is reporting around 50% at most times. I have tried killing the processes to see what may happen and there are no negative effects but the processes just seem to come back eventually if I check an hour (not exact) later there they are again.
I assume it's impossible for 200% of CPU to be used right now but what I'm wondering is would 100% CPU on one process equal to 50% when considering that nothing uses both cores yet?
Any clues what these processes (android.process.acore) are and if there is anything I can do. If someone can suggest a good way to take screens I will be happy to post one as well.

Use Screenshot ER instead of AndroSS. Curious to your findings. Massive battery drain here. I dropped 10% in 45 minutes doing absolutely nothing. Nothing rogue in my battery stats...

Now I did notice that both say com.fede.launcher. This seems to say to me it is launcher pro as the dev is Federico Carnales. Im really hoping the 2 aren't in compatible as I've been using this since it came out in my D1 and I am damn used to it. Anyways here is my screen shot.

Also I should mention that when I kill one process it kills both at the same time. I am using 0 of the launcher pro widgets so it doesn't seem to be polling or syncing. And nothing acts any differently (that I can see) after the kill. No restart of launcher or anything.

Pretty sure Fed said LP/LP+ isn't tested to work on gingerbread yet
Maybe that'll be fixed once he's done w/ the rewrite?
Wish I could help ya tho...just another pointless reply here

I see this, 100% CPU on 1 or more threads of a single process on multiprocessor linux boxes where that process has run away/spinning in code... on a 2 processor system the system would look always loaded 50% or more...

Hey that's news to me man. Honestly by the time I put GB on my D1 I couldn't tell a difference because my battery was suffering as is so it could have been doing it there too...
Mista Wolf are you running launcher pro as well?

That was my guess on the cores was 100% of of what it has the ability to use right now is only 50% of available.

I am using the stock Blur launcher. My battery is just taking a beating...
I really want to figure this out because I love this ROM.

I swapped out to launcher ex I was pretty much able to duplicate my lp+ setup I'll see what happens I'm good so far no return. We'll see if this cures my battery issues.
Sent from my DROID BIONIC using XDA App

And its back... so I seem to be getting this no matter what launcher I use on top of stock. Can anyone else confirm this? Could someone that can dig deeper into this try to duplicate and find out why these processes seem to be taxing the cpu so much or are there any resources I can pull that could help me get this figured out?

I get great battery life with launcher pro. It may not be optimized for gingerbread(or so it's said) but it runs great for me. I was getting a day and a half on Eclipse for the x2.

I have been running zeam launcher, and have had absolutely amazing battery life, unplugged at 6:30, and will still be in the 70's with light use, or 60's with moderate use come quitting time.

I installed Android System Info and checked that my android.process.acore was not using any cpu cycles (0%). I use the Go Launcher. I would suggest trying the dreaded "Factory Hard Reset". I know it's a pain and time consuming, but it cures a lot of random ills.
Good luck.

Yeah I am doing a reinstall with a rewipe at the moment (I know this isn't hard reset). I am a very process oriented person so I doubt I missed any of the wipe/formats needed for Unleashed but I'm going to give it another try.
After doing a bit of google searching for "android.process.acore" I find ALOT of people with the exact same issues (on different phones) all with non-stock launchers. I have found a few suggested fixes. Like removing widgets from stock browser and all other launchers (I have a few right now as I've been testing and trying to work around.
This does seem to be a widespread problem though for more than just us.
Geezer could you please keep checking on Android System Info for me randomly (this is not an all of the time thing) I can kill the process and it will stay dead for a seemingly random amount of time (haven't been able to notice a pattern yet) at seemingly random points(I'm not noticing any one action causing this). But from the other references I'm seeing to this problem all seem to revolve around updating but most for different things... I have been taking note of PID in Android System info and searching for the PID in CATLOG I am finding references to the PID but honestly I don't see any glaring problems but I'm no dev and I don't fully understand what it is telling me. If I provide LOGCAT of the process could someone translate for me?

Zeam launcher is awesome.

I checked out zeam but I just can't deal with how minimal it is don't get me wrong I run very minimal home screens (nearly 0 widgets but battery and clock and only 2 home screens. I just can't deal with the lack of options in zeam. I don't really have any further leads on this I've been fighting with it as I've had chances at work but still no luck. Does anyone here know how to actually read a logcat or will that even get me what I need?

FWIW, I'm getting ABYSMAL battery life (7h4m from full charge to shutdown as of my last cycle just now), with only 8 minutes of phone calls, light surfing, light texting, email sysncs at 1/hour.
I'm running GoLauncher with UNL3EASH3D v4. I have yet to see the process you describe (and I've been checking it pretty frequently trying to track down my drain- in fact, without exception every time I check, Android System Info is the process using the highest cycles at about 10-13%). I also used Go with stock for a day or so and didn't have this level of drain. HOWEVER, I didn't duplicate my stock setup when i flashed unleashed, so it may well be unrelated to the ROM.
I AM seeing waaaaaay too much awake time on the stock battery stats screen.
I'm about to do a wipe and reinstall and run minimal for a few days to see if I can pinpoint anything. Trying to hold out for the update if I can... (Love the ROM, so really don't wanna go stock)

CM7 really bad battery life?

Hey everyone. I'm brand new to the community and just successfully rooted and installed the latest release of CM7. I tried looking around the forums but couldnt find any answers about getting really bad battery life on the Incredible specifically with CM7. I am actually getting worse battery life than with my stock ROM. I havent adjusted any settings but I did use a battery calibration app after the ROM was installed. There is some problems with the battery readings, specifically with starting at ~90% (I did not overcharge, battery calibration app told me when to calibrate at 100%) and then the quick and unannounced drop off at ~20%.

Anyone have any ideas as to how I might be able to improve this or what I am doing wrong? Thanks in advance.

Mine is like this also.
My uptime and wake time are identical so something in the phone is keeping it awake. I'm yet to find out what it is.
What's strange is that I use my display quite a bit (1 and a half hours), yet it only uses 10% and it says cell standby uses the most??

Cm7 is the best battery life for me.
Get cpu spy the app and check to see if your phone is going into deep sleep

Is WiFi on always, or are you updating mail, weather, Facebook and so all the time?

gmail is on push
facebook notifications just pop up asap I dunno...
that's it..
Got juicedefender on, but don't want it to disconnect my connection when the phone is idle because I still want to receive notifications almost instantly.. Plus on the battery widget I had "currentwidget" it only used 30mA idle with connectivity on
and like 29mA with it off, so no big deal..
Also, wifi is on but doesn't turn on when the screen is off - it uses 3g....
Today I didn't use my phone much, just sitting at home pretty much and sent about 10 texts, it's down to 55% when I took it off charge about 10 hours ago. But maybe because my wake time is identical to my uptime that could mean something is using the battery...

This is what I do. If your phone doesn't go into deep sleep then it will use alot more power than it should

Go to the development section, and find the kernel called tiamat. Flash version 1.14 in recovery.
Download set cpu, set whatever max and min freq you want and set the governor in the drop down menu to smartass v2.

Well this has spiraled downhill fast for me. I attempted to flash the kernel mentioned above. I cleared both the caches and then my phone got stuck on the HTC logo at boot. I attempted to restore using clockwork but I got an MD5 error. No big deal, just had a fresh root anyways. did a factory reset, re installed CM7 and Gapps, everything booted up fine and I got all the basics set up again. Then went back into recovery to flash the kernel and again it is getting stuck on the boot screen. Anyone have any ideas? the effort and help is greatly appreciated

Are you sure that you downloaded the Kernel for the Incredible S and not for another device?
I just flashed Timant 1.1.5 with no problems.
You could also try using the Kernel Updatet Utility.

Just double checked
This is the kernel that the previous poster told me to use, specifically to use 1.1.4. I guess I can try it with 1.1.5 and see if that works :S No idea why 1.1.4 from that site won't work though
**EDIT** attempting to flash 1.1.5 also results in getting locked on the bootscreen -.-

You're the first person I've seen have any issue flashing tiamat.
When flashing don't wipe anything and leave your phone for a bit it might take a bit longer to boot up.

FML. newbie mistake. for whatever reason the http://tiamat-dev.com/ site only has links on the side for the Droid Incredible 2 and not the Incredible S. As such, I was, in fact, using the wrong kernel. I managed to find a direct link/ elsewhere on the in the forums. Disaster has been averted. I will report back on (hopefully) battery life increase. Thank you everyone for your time.

Yeah dude cm nightlies 114 and tiamat 1.14 smartass v2 UV - 75 = insane battery life. Car charger is a waste of money with these settings.

Any chance you could take the time to tell me what nightlies are? and how much different they might be from regular CM releases? also what do you mean by "UV - 75"?

Nightlies are the nightly builds of cm7 they are released every day around noon and contain very few updates of cm7 but are the main way of beta testing. The version you have downloaded is essentially nightlies 109 because 108 was deemed bug free the stable nightlies 109 was declared the next user friendly version of cm7. There is a thread for this on the Dev forum.
As for UV it stands for undervolting. Read about it if you want. If not grab incredicontrol from the market. After opening you'll see the voltage settings for each CPU freq just hit all - 3 times you'll be undervolted by 75.

Great App (pimp My Rom)

I suggest everyone download a great app called "pimp my rom" its in the play store i have tested almost everything on the fascinate and have not recived one error IT WORKS GREAT!!!!!

most "performance apps" just add things to build.prop, system/etc/init.d/****, or just mass-force-stop apps that just restart due to programming, most things apps liek those, and pimp-my-rom do can be done by the user, they just make it easier with a snappy UI for the
uneducated root-user" with no offence to any lol, even before i built my rom, and some apps, ive done more then the tweaks for stability that these aps do since i was brought up with linux, mid-early-to-newer windows(95-7), and have been observing codes since i was 7 (and im currently 18 as of now), so if u look at different Tutorials for linux-distros, and compare to Android alot are basicly the same as android is based of linux, just some terminal commands are different, and we use superuser/Super SU, to do root-commands like linux's sudo, but not all codes can give 100% positives for all things, or even 100% false (unless it was just a scam paid app that gives random official apps like facebook, gmail, google play store once, a false positive; most newer "official security apps", arent really coded to do as they say they do, some look at their permissions and if say "android.permissions.ACCESS_SUPERUSER" is one, it counts it as generic malware, because it reads its a root-capable app, even if its just a blank package with only permissions, no images, no operation codes "src/", just a blank package with no XML's but Androidmaniefest.xml for permisssions+package name/versions lol i always hated when people use the common day paranoia of viruses now a days, but linux-based devices are least likely to get viruses, as androids newer versions have bug-fixes, securities, and detections, +most of the apps that ARE malware need root, that the common user doesnt know what it is lol, i bet u if u have with people who ARE NOT developers, and just use it for games+phone/texting if u ask them if their phones rooted, ask what their operating software for their computer is, or even what android:IOS(apple) version are u on, the most common answers ive been given here in Parkersburg, are(in question order):
-whats rooted?
-umm, idk what that is, i was told it was a windows 8 computeror has a windows 8 sticker)?... idk
-?...?....what?...
so most average-day people arent educated on the true purpose androids can give u when a Root-User(SU) since its almost FULL Linux!, like pin-testing software or networks, computer network analysis, Syncing files, Virtual Distribution Testing, OTA USB Triggers to reprogram Computers OS On-Computer-Boot, Reverse tracking Locations/Numbers, Re-Routing where people can Ping you on windows/linux/Mas OS to ANY location path (fun when i have people do it and it makes it look like in in the United States FSA Headquarters, Google Headquarters, then to the NASA Building), Nintendo Zone Hotspot for free special Gold-Bottomed mii's if u cant goto a official Zone, MAC-Address spoofing on-boot, FULL VPN-Capabilities not just location+site unblocking, DNS Location Changing(so any website sees u dont exist/different Global location/Full Network Privlages, even adding more things then BusyBox could ever do! and more then 99% of people dont know that the $100+
USD Device they have in their hands can do more things then an average Super Computer of the mid-to-late 2000s sometimes even better then super computers today even, just not as fast as the super computers ive messed with had 12*16GB Ram-sticks and a 200GB Swap backup XD
u think high-speed internets fast sometimes, u try downloading 5TB(1024GB*5) of files in under 2 mins with DSL connections XDD, so basicly what im trying to say is that not all apps are what they say to be, some work, some dont, some are just scams for a quick buck to do something that will just make it worse, or somethign u have to test longer then the Google Play's 15Min refund period that if its past that, they dont have to give refunds lol

btw... why are u flashing roms on a Note2 if this specific forum is for the Samsung Fascinate SCH-I500 (fascinatemtd code_name)? if u flash roms in this forum no1 is paying u for a bricked device u didnt read the disclaimer from the rom-developer is its for a FASCINATE, but we are a friendly forum where critisism is to be done lightly, and family-friendly, Root-Apps always have the default disclaimer whether posted or not of
"USE AT YOUR OWN RISK!, Not all tweaks/mods/features are meant for EVERY DEVICE, there is over thousands of device models and cannot be tested on all, MAKE BACKUPS, AS I AM NOT RESPONCABLE IF U BRICK YOUR DEVICE FOR NOT FOLLOWING THIS DISCLAIMER!"
as rooting your device/Flashign a rooted rom is a "USER ACTION", meaning u made the choice to do it, so nobody else is responcible for the damages cause when u voided your warrenty due to user modifications if u arent using a "DEVELOPER_EDITION", like i use, all-in-all user modifications whether its Hardware, Software, Add-Ons, or even accidentials, its still done by user actions, and nobody else is responcible for refurbishing, remanufacturing, or repairs if done by the owner of the device itself, with or without approval of others
*Edit#1*if u really want me to prove it to you, u can post the APK file u installed, as i can run whats called a Signature_test, and compare the sizes, MD5-Hash, and everything u might need to see if its the official Pimp-My-Rom App, and not a Uuser-Modded version of the open-sourced app as it is

[BATTERY IMPROVEMENT] Works every time half the time :)

DISCLAIMER AS PER USUAL: YOU DO IT AT YOUR OWN RISK.
Although procedure itself is simple enough, but as alway, anything involving flashing, especially firmware has it's risks.
Oki doki. Time to come out in the open
Prelude. I was hard pressed to get 4h screen on time in 10-12h off charger. Then i screwed something up (irrelevant ) and had to reflash stock images.
Now my next findings are sure to attract so flaming from more experienced users that will say "it's placebo", "it doesn't work like that" etc. While I don't have screenies to confirm pre flash stats, i have gathered a few post flash stats. Here we go.
Some cycles are missing, since i either accidently deleted screenies or forgot to take them. But that should give you a general idea. WiFi used mainly, apart from last cycle, where 12 were on data only and the rest was while connected to wifi and reading a book in fbreader.

And this is ROM/KERNEL i used before and after flashing images. Note, kernel has been updates since, but it didn't make much difference.
So for me it's fairly conclusive, reflashing stock images has GREATLY improved my battery life. I had a few chats and we came to a conclusion that it is possible that at the factory device has simply not been flashed "properly", mass flashing differs from your usual .img flashing normally.
What you think...Well, it's up to you for decide. I know few more people who've done the same, and while their improvement is not as drastic as mine, it is still an improvement.
Please vote AFTER you try it, and after min of 2 cycles.
How to in post no2

Simply follow this great guide by efrant. Keep in mind it will wipe your storage, so backup all the pics and other stuff.
Before you do it, take below quote into consideration if you use google wallet.

Oh yes, you have to reset Google wallet before you flash it. You would log into Google wallet then settings and click reset wallet. I remember this from galaxy nexus days.

efrants guide
People who are more experienced will know how to cut corners If you don't know what you are doing, I suggest you follow efrants guide to the letter. This way you'll learn a fair bit too.
Same process for every images version. Also, I ALWAYS do it for any images update, since I'm not a believer in patching. I might be wrong, but hey, it works for me. So my personal recomendation would be to redo this after every new OTA.
So:
1. Backup your "SD" contents.
2. Flash ALL stock images as per efrants guide (or any other way if you know how to)
3. You are most likely to get stuck on boot. Hold power button, shut down, reboot into recovery. Once you see broken droid hold power button and tap +vol. Once in recovery do factory reset. If you don't get stuck on boot, still do it.
4. Boot on stock. It's a good idea to transfer your rom and kernel onto sd now since you can't mount sd in recovery.
5. Reboot into bootloader and proceed to push recovery and then flash your previous setup (ROM/KERNEL)/
How to push recovery.
Code:
fastboot flash recovery recovery-image-name.img

All on auto, the only two things i have disabled is gnow and location reporting (which is primarily used for gnow anyway) and had that disabled from day one. The rest of the settings are irrelevant, since they are the same from before i reflashed stock.

Interesting, be good to see what others report.
If i hear a few good reports, i might take the plunge next week.
Edit: might just be Rasbean jelly giving you good battery life!

Cool, I'll give it a try and see what it does!
I'm struggling to get +4 hours of battery life ATM, so let's hope this helps.

It's not. Wait till some Americans who done the same thing wake up
There are about 4-5 more people who report the same, that's why i decided to share. Had to make sure first that it's not a fluke.

Re: [BATTERY IMPROVEMENT] Works 100% so far.
The thing that's helping battery life here isn't the reflash, it's the factory reset that happened when you did it.

I would tend to agree. But which would be the cause, removed culprit user installed app(s) or something not set as intended from factory as a result of mass flash/ reset etc at factory? Or both?
Maybe even a difference between OTA updating new units after setup or before?
Would be easy to test the theory by just doing a factory reset without re-flashing and see if it makes a difference.

I did think of that. Thing is flashing ROM fresh IS factory reset. Factory reset doesn't do more than delete all the data and maybe reflash /system. So i disagree with you here Rusty. Think about it. I took my time to carefully evaluate changes, and you might know from my time in Sensation forum that I do look into things before posting it.

See above.
Also, apps have nothing to do with it, since my (and other people) setup is identical to what it was before doing that.
And thanks to the person voting NO. I guess following simple request is too difficult.
If you guys are sceptical, do it before you do next fresh install since you don't lose anything and report back.

I can vouch for this experiment that we somehow agreed to without even hesitating lol.
Personally, i manually installed EVERYTHING. no nandroid or titanium back up. Before i would get roughly 9hr phone usage with 2.5-3 hrs battery. After going through this i now get 13-14hrs phone usage with 4-4.5 screen on. I know that's normal for some but compared to what i had before, is an improvement. This was just in the first cycle. I'm on my second and wool report back when I'm done

Not sure. But someone already had very decent battery life and extended it by another 0.5-1h screen on. I guess you wouldn't lose anything if you tried. Just a half an hour of setting things up.

Make a nandroid. You have nothing to lose but time. It's the weekend anyway.

Dont want to say anything but on screenshoots there is practically no apps other than browser or taptalk, play a game, watch a clip on YT, listen to some music ohh and switch off WiFi. Phone is to be used outside where you dont have a WiFi, At home I have my Laptop that is far much better than than a phone to read stuff, and XBox that is far much better for gaming....
I could probably pull 8h screen if I switch everything off sans WiFi and just have web browser opened on one page.
Ohh And I'm on stock since day 1 + had to reflash image due to kernel net being compatibile with screen sensitivity driver .... No changes, What you have on images wont repeat itself outdoors.
Look at that screen where you dont have WiFi on. Your usage dropped by 8hrs screen time by 1hr and still no phonecalls, txt, nothing really.... just chrome
I get 3hrs 30min screen + 17hrs usage with music in bacground, quick game + and reading, no reception for about 8hrs or if there is any its 1bar....(and that drains the battery)

Ok. I think I have to explain something. This is absolutely not about how or what for phone is used. I used it in the same way before I flashed images.
Concentrate on the MAIN thing. Same usage, same rom and kernel, same settings, same apps. The only difference is battery life after flashing stock images files. Immediately.

I am loosing my mind! Note eating battery and superslow

Hi!
My Note has for a quite long time now been slow, laggy and eating battery.
Didn't mind, had a car charger, suspected old battery and clogged storage.
About a week ago it came to a complete stop, taking 30 sec to open facebook.
And typing in Swiftkey an impossibillity, having keystrokes on a 5-10sec lag.
So finally i got a new battery, whiped the phone clean.
Flashed the phone with a fresh rom (Team Union JB XXLT4 V7)
Installed my apps manually, making shure no crap cache was brought.
Formatted internal storage and got a new 32Gb SanDisk Ultra card.
Fresh start, fast phone right? no.
Apps still unusably slow, typing on swiftkey impossible without lagging.
Battery from a full charge last about 6h with light usage.
Would like to stay on TW only for the MHL capability, but now i am open to anything.
Can't really afford a new phone, so if this can't get resolved ill switch to my old 3GS.
What do i do now?
What can i try?

YOu should try AOSP/AOKP Roms!!!

I think one of the apps you have is causing the problem.
When i had the same problem it turned out to be the podcasting app i had.

Or go to the terminal and run top, see whats eating the cpu.

have you try to replace new battery ?!

Well, yeah couldn't find any original though, and don't want to wait weeks for a shipment, so got a copy brand "ENERGY" spacy logo and made here in Thailand. Only 2350mAh compared to the original 2500mAh.
Found that the new battery didn't really make any difference, about the same.
So worried i got new but crappy battery I'm now back on original, without any noticable change.
Considering getting a external charger and carrying the spare battery, that is not really a solution either.
Got get this phone working reliably soon, or i need to find a replacement.
Appreciate the tips, and ill try and make a study with "top" and get back to you guys.
Maybe i have a energy hog after all...

It's a pain in the butt, but it looks like the only way to resolve it is to do a clean wipe, then install each
app one by one, giving yourself a day or two of usage. Sucks, but it sure sounds like one app is
screwing up another one. Any chance you can (shudder) use a "memory cleaner/program closer"
after you use each app, to make sure it's closed as a test? Sounds like something sure is
interacting with something else.

USe Greenify and hibernate all apps!!!

Check your Google account settings. If you have sync Internet ticked disable it.

Really?
I thought my battery life was bad. 7h15m with 45 min screen time after charging my battery is at 67%
That is with wifi and bluetooth (with music playing) on and connected.
GPU overclocked and lowest step 200mhz(from 133 and max 400) and cpu up to 1550 Mhz.(okay, i did reduce the voltages, sue me)
and google location service on.
On original battery (dec 2011), that is about to die (screen starts glitching around 30%)
Somehow you are doing it wrong.

You would be surprised at what a speed deference you will get and battery life with aosp roms I have used tw and aosp and always go back to aosp based when tw starts to get laggy. But as most have said most likely a app causing your problem you should try install new Rom with all wipes inclueding preload I think thats what its called and make sure that media scan is not always running

What's this snarkyness that's infected xda?
Shure wasn't around back in the WM days.
This is and or was a very "General" issue with my phone, as i am still not entierely shure is a plain software issue.
However i've made the switch to a or the PA-rom out of desperation.
Still too early too tell, as it is first day after flash, but feels smoother.
What is driving me mad on PA is the lack of lockscreen-homebutton-torch.
Also a bit dissapointed in "Screen Mode" dynamic mode missing.
Missning SPen->screenshot->notetaking is bugging me aswell, but i'm shure ill find some replacement thing for that.
EDIT:
You, know what.
I apoligise if i posted this in the wrong place.
