Warning: AppBrain kills your battery

My battery was inexplicably draining and SystemMonitor showed continuous 100% cpu usage even though it didnt show any individual app using a lot of CPU.
So, one at a time, I started killing apps and waiting a few seconds to see which app was hosing my CPU.
No doubt, the subject of this post lead you to the correct answer: AppBrain.
AppBrain is a fantastic app, but it was using 100% of my CPU at 1.136GHz and it will killing my battery. I don't know why SystemMonitor didn't show it as using much CPU time, but killing it did the trick.
FYI: I am on BakedSnack 1.5 on Kernel #4 (the "Fastest" Kernel).

How long have you had app brain?

I've only had it for a few days.
I only started monitoring my battery for differences because I just upgraded to BakedSnack 1.5 and whenever i install a new ROM i'm especially careful about battery life.

Please turn on system monitoring in System Panel to see what was historically killing your battery.
Its possible it could have gone rogue, but I've never seen that happen.

Did you come to this conclusion only after you turned off AppBrain and noticed a decrease in CPU usage? Did you try re-installing AppBrain to verify that it did in fact, increase CPU usage to 100% again? Sounds a bit like you're jumping the gun on this conclusion.

never have a problem with appbrain. Its latest version make it useful.

Yea, i always install app brain and its never gave me problems like that.

I think my method of
Watch CPU meter sit at 100% for 5 seconds
if CPU remains at 100% kill 1 app and goto step 1
the most recent killed app is your culprit
is pretty sound. It has worked for me on many OS'es over the years.
Nonetheless, at your requests I have uninstalled and reinstalled the app and seen the same behavior. System Monitor doesnt show any individual app eating the CPU but the CPU meter is at 100%.
I don't know what that means except that, for now, I am forgoing AppBrain.

System Panel shows CPU cycles per running app on the main screen. What are the stats?

appbrain works great here too... this is not a common problem with the app.... something else is messed

i have had no issues with appbrain. on any ROM i've used. have you tried to remove it and reinstall it to see if your issue returns?

You might be right here I uninstalled it and my battery went back to normal

Been using appbrain since i got my evo. no problems here.

The whole, "you are dumb it isn't appbrain, it has never given me a problem" needs to be kept out of this thread. he has a sound logical method, regardless of what a system monitor shows. If terminating appbrain ends a 100% cpu lock, then obviously it is a problem with appbrain or the kernel he is running.
how bout instead of everyone saying, "works fine here!" someone with the same kernel and rom as him post up and let him know how it works for them.
how would it make you feel if you were in his situation if someone said
"works fine here and has always worked fine on my evo"
or
"I am using the same rom as you and the same kernel and I do not have the issue"
The first is useless and assholeish, the second is called contributing and is what these forums are about

begone troll. you have added nothing here.
i saw no one in here that was rude or nasty to the OP.
i see several folks letting the OP know that app brain in general seems to work ok.
i see a few folks asking basic troubleshooting questions.
i see a few folks throwing out basic troubelshooting steps.

Just a reminder XDA has rules regarding people policing forums XD
Annyway, I know for a fact that appbrain has kept my phone from sleeping. Using system panel, I have killed ALL apps, and slowly let them return. If my phone sleeps, I exclude the process so it won't be killed. After several repeats, uninstalls, and tests, it is appbrain that keeps the phone awake, though sporadically.
Just throwing that out there

you provided some kinda of feedback. that is good.
skydeaner provided nothing but an attempt to stir the pot.
and you call me out for it?
wow.

I actually noticed my battery life being god awful the last couple of days (just installed app brain 3 days ago). At the moment I was going back to CM Rom however once i get there I will check to see if it is the cause as well.

I also noticed the same thing about appbrain on my Droid X with leaked 2.2. I installed appbrain about 3 days ago and I started noticing my battery draining quite rapidly.
What made it really obvious that my battery was draining a lot faster than normal was that I had just disconnected my phone from the wall charger (100% charge) at around 6:45 am; I had not used my phone at all, but when I checked it at work at 8:30 am, my battery was already at 60%......that's crazy because my battery usually still reads between 90-100% at that time with no use.
Since appbrain was the only app I had added in the past few days, I stopped it from starting up at boot with autostart, and now my battery is back to normal. I think I am just going to uninstall the app completely.

There is an app you can install that works in conjunction with appbrain. I forget the name but it auto downloads and installs apps you pick in appbrain... even from a computer. Did you install something like that? I have heard it is bad on battery life

[Q] Help with battery Life on my Lg G2x Please! (without updating the phone)

Hey there im brand new to this forum and android in general i just sitched from an iphone to the Lg G2x. I have to say the G2x is incredible but my battery life isn't i get on average 5 to 6 hrs of battery life (lose about 20% every hour) as others i have installed juice defender ultimate, setcpu, and watchdog. In addition to all these apps i uninstalled apps like T-mobile app pack and wifi calling because these apparently use up a lot of battery. So my question is if there any tips you guys can give me or setting for my phone or apps because maybe i have everything i need installed but with the wrong settings any help at all would be great thank you in advance
Info that might help:
As of now the juice defender app reports: 1.36x improvement

Well im assuming your running stock ROM and kernel...so the best and easiest thing i can tell you is just buy an extended battery ....they last alot longer, if you get the right one...

Download spare parts, go to battery history, and look at partial wake lock.
If you see a bar going across the screen or even most of the way, that's your culprit.
Also games like Words With Friends kills battery life with its polling service.

@Texan28
Well idk i tried to post pictures to display all that info but since im a new member i cant post links to pictures yet and well how much are they because ive heard there rather expensive
@ enoch861
No i would say average use most of the time just texting (usually is periodic not constant) , very little email checking and little or no facebook use but most of the time the phone is just sitting like for example right now Cell Stanby is at:49% and phone idle at 52% personally i think its to high but idk is that normal?
@Scyth3
Installed the app but no apps seem to be giving trouble all that have a status bar are very small

Once you've confirmed that you're not seeing any rogue app activity then uninstall watchdog. You don't need an app monitor or task killer running constantly on your phone.
Turn off auto brightness and set screen brightness somewhere around 20-25%. Under Settings > Wireless & Networks > Wifi Settings > *Press Menu* > Advanced Settings change wifi sleep policy to never. Turn wifi off when you're not going to be connected to a wifi network. Set your email/Facebook/twitter/weather/etc apps to sync either manually or at least less frequently.
Your biggest battery killers are going to be your screen brightness and your cellular radio. Juice defender can help control some of the cell radio by keeping data turned off when you don't need it. Also consider if you have poor signal your phone might also be always switching from 4G to 2G then it'll use more battery.
Don't bother with disabling GPS. Your phone only uses it when an app needs it anyway.
G2X CM7

Also, I'm assuming you've rooted your phone since you said you've removed wifi calling and other T-Mobile stuff. In that case, open setcpu and create a couple of profiles. Create a Screen Off profile with max/min values of 312/216MHz. Also create an In Call profile with max/min values of 1000/216 and set the priority slider higher than the screen off profile. I do this because when the screen goes off during a phone call I still want my phone to have plenty of processor power available. And I don't set it lower than 1000 because I'm often doing other things with my phone while I'm on a call.

Then there's something wrong with your phone or a rogue app. I text a lot also and use my phone moderately to heavily. But I still get a whole day of use from the phone. Its surprising.

@phburks I Actually have those settings on my phone however the setcpu i dont because i cant set those numbers for some reason it only lets me set default for example it goes from 245MHz to 384MHz (on the sliding adjuster)
@enoch861 really is there any tests i can run to find out whats really wrong?

No sir. Not that I know of.
But I would try to do a reset of the phone first anand run it a couple of days without really installing anything. If you get better battery life then it could be due to an app that you had installed. At that point you can start reinstalling your Apps one at a time in order of importance.
Now of that doesn't fix it, it could be a hardware issue.

In setcpu have you tried hitting Menu > Device Selection and then selecting the Tegra 2 option at the top? You might have it set up for the wrong device.
As for the battery life in general, 5-6 hours on light to moderate usage as you described is not normal for this phone. When I was on my stock rom unrooted I could still get at least 10-12 good hours and I use my phone a lot, mostly for texting and web browsing.
Are you in an area with weak cell signal?
Are there any other preinstalled apps from T-Mobile that are still installed?
G2X CM7

@enoch861 will the reset un-root and re-lock the phone?
@phburks
ok thnx i fixed the setcpu settings and no not really but idk if having in on a gsm carrier(Simple Mobile) makes a difference but yea thats why im trying to get this fixed because 5-6 hrs is really not enough i mean if i can at least get it to 10-12 hrs id be happy with that its great improvement and um well just google maps, news and weather, smarshare, talk, telenav, voicew search, youtube etc the only ones i made sure to get rid of was t-mobile app pack and wifi calling

It shouldn't unroot it.
what do you mean by relock?

I'd get rid of telenav too.
As for a reset, do you have clockworkmod recovery installed? Just boot into that and do a full reset. You wont lose root but you WILL lose any apps you installed, personal settings, text messages.

@enoch861
what i meant with relock is that its currently unlocked but if i do a factory restore will it alter that ?
@phburks
i actually dont but as long as my phone remains unlocked and rooted im willing to try resetting it after all ove heard good things about it helping with battery life but can you walk me through it?

No. It shouldn't.

If by unlocking you mean the SIM being unlocked to work on other cell networks, then you have nothing to worry about. A factory reset wont mess with that
As for performing a factory reset, go into Settings > Privacy and choose Factory Data Reset. Make sure you back up any texts/MMS you want to keep. All personal files/photos on your sdcard will be preserved but you'll have to reinstall any apps you want.
Since you still have stock recovery you can also power off the phone and then hold Volume Down + Power for like 10 or more seconds till you see the Android unpacking icon, and it will reset that way.
It shouldn't mess with root.

If your phone's rooted, which it seems to be, download the battery calibration app from the market. It's free, and helped my battery life immensely. Basically charge it up to 100%, use the app. It deletes the battery stats file so android can make a new one. Run it all the way down to empty, then charge it back up to 100% and you should be good to go.

how exactly is a program that measures the battery helping the battery life?
OP, I am using Xboarders latest 2.3.3 rom and have had the phone on 9 hours and am at 70%. I use set cpu to slow down teh processor when the screen is off and I use juice defender to turn off data, wifi, etc when the screen is off.

@ enoch861 thanks thats a relief
@phburks thanks im gonna go ahead and try it by the way when i perform it is there anything i should be doing or avoid doing (For example removieng certain apps or anything like that ?)
@Danishswag Tried it already it didnt help

Let apps access data when it's turned off?

Hi guys,
I'm sorry if there's a thread about this but I don't even know what keywords to search. Since the Atrix has such brutal battery life I'm wondering something. Is it possible to turn my wifi and data off but have some apps override that? I use whatsapp messenger and would like to allow it to access data so I can still receive messages. Possible or not?

It's not quite what you asked, but Juicedefender will automatically disable all your data, and temporarily re-enable it in user-defined intervals to let your apps update.

Whoa whoa, how does that work? Make sure you figure out what is holding wakelocks and hammering the CPU, that's the quickest way to fix it, the Atrix should have one of the best battery lives of any smartphone.

I don't know much about this kind of stuff, so don't really know how to go about that. Was getting about 6-8 hours with minimal usage so I installed a new kernel and it seems a bit better. I've seen some people report 1.5 -3 days of battery life but I've never cleared more than 10 hours probably.

If on Froyo: in dialer: *#*#4636#*#* should take you to a menu, go to the Battery History application and look at the running vs. screen on percentage. If you stay in high signal areas most of the time and you don't do anything that holds wakelock intentionally (playing music, non-C2DM IM clients), then you should only see about another 2-3 percent tacked onto the screen on time for your total phone awake percentage. If not, look up the partial wakelock since unplugged and check to see what's holding wakelock. If Android OS, reboot your phone liberally. If it's the dialer, same deal. If it's a user-installed application, either figure out how to get it to stop or delete it.
From there install current widgets or something that read your mA drain and ensure it doesn't jump above 10 mA while idle.
Also make sure you use that dialer code to see if you can switch your phone's radio to GSM Auto (PRL) for better battery life in poor signal areas.

[Q] After Root, Phone Won't Sleep - First Time Root

Hey everyone, just rooted and unlocked for AOKP for my first time. Firstly the mod is great and I'll likely never go back to stock Touch Wiz, but my problem so far is that I can't figure out what is intermittently waking up my phone and preventing it from sleeping. Before the root and using the same minimal amount of apps my battery life was outstanding and the battery history details showed that it was not waking up when idle. Any input? Thanks in advance.

Search the forums for the free XDA version of Better Battery Stats. Install this app and select partial wakelocks from the drop down. This should give you some insight into what is causing the wakelocks.

HTC One XL Battery Drain

Alright guys, I've pretty much had it with this phone and AT&T. This is the 4th issue I've had on my phone. Basically, my battery dies within 3 hours no matter what I do. I turned off all connectivity in class this morning and put it in my pocket at 90%, 2 hours later it was at 29% with "Google Services" as the main cause of the drain. I thought it was weird because my internet was still off. This is my third One XL due to numerous problems in the hardware, at this point I just want a totally different phone which I know they'll offer me. But I'd rather get a Nexus 4 or try to hold out for the Nexus 5. Any ideas on what I can do to maybe temporarily fix it until October?

Thanks! I'll let my phone recharge up and try to replicate the issue to see what's causing it and I'll see where to go from there.

Try uninstalling all your apps, keeping only the necessities. If you went through 3 phones already, the problem is probably you, not the phone itself.

I get this sometimes, I usually fix it by uninstalling updates to play store and deleting app data from play services and play store and the app that battery usage says is the problem. Then reboot.
There's probably an easier way to fix it but I haven't found it.

I would ruu. And install gsam right away. Then I would monitor battery drain over a day or two. If gsam reports no wakelocks but it keeps draining quickly, it's a hardware issue. If it's not draining quickly any more, install a few apps a day until you find the draining culprit.

Apparently there was an error with sync that kept my phone awake while it tried to finish it. A reboot and refreshing the sync seems to have done the trick. Thanks guys! I'm still jumping ship when/if the nexus 5 is released.
