[Q] Stock myTouch 4g, 100% CPU

Hi All,
I have a mt4g which is rooted with S=Off. I switch between the Sense launcher and Launcher Pro Plus. Usual apps on the phone, not too many.
For last week or so, I have been seeing that sometimes the phone gets really really laggy and Norton Util tells me that the CPU is 100%.
Also, I think most of the times, when this happens, I see a Sync icon up top. I do not sync a lot, just 2 GMail Inboxes and weather (every 6 hours). But I do see that Sync icon most of the times when this lagging happens.
I have tried removing apps, but this still seems to be a problem. I have see somewhere that turning the USB debugging to ON has helped many, but did not work for me.
I tried CM7 RC1 when it was out, but didnt like it (stock camera etc...) and I restored back to my stock ROM. Could this have done something?
Thanks
Ravneet

On your home screen hit menu key. Go to settings. Select accounts and sync. See what all is listed there. Chances are something with sense is constantly syncing.
Disable everything from syncing. See if the problem goes away. If so turn on one thing at a time until you find the culprit.
Hope that puts you in the right direction.

Have tried that. When I go there nothing is synching. Strange.
I have tried to remove all accounts from synch but still see the problem.
Went into recovery and wiped the cache about a hour ago. So far so good. Hope it stays this way.

I've noticed that there are apps that as soon as i download them, and open them that my cpu will go to 100% until I reboot my phone. System panel is a good app that isn't too obtrusive that will tell you exactly what app is doing what.
Have you installed anything new lately?

I uninstalled everything new.
Moreover I think every time this happens the battery is less than 30%. Maybe in low battery profile there are some apps which are over utilizing the CPU.

There's a couple threads like this. The stock Rom seems to have issues running rooted. Best bet would be to flash a different rom

Turn on USB Debugging... See if that does anything

USB debugging is set to ON.

@NicGraner: Why would the stock ROM have problems with being rooted?
I am still having this problem. Uninstalled everything that is not important.
The phone just becomes unusable and I have to reboot. Un-installed Watchdog Lite too, as I thought since it is monitoring, it is taking up some CPU in background too.
No widgets on the home screens.
I guess I am gonna do a full refresh using the PDxxx.zip and go back to stock stock and then see what happens. not sure if I will lose my root once I do that.

Try the royal glacier rom it's solid stable and the sh!t
http://www.thepetitionsite.com/2/stop-t-mobile-from-being-bought-by-att/.......

I returned 5 phones for this exact problem, then I finally got one where the usb debugging trick actually worked. Before that I was just using OSmonitor from the market to see when I was hitting 100% then I would have to yank the battery as that was the only thing that would make it stop.
When I got this new phone I installed os monitor and waited for it to happen again, which it did, then I turned on usb debugging and watched my cpu usage graph drop to 0%. SUCCESS! Unfortunately since this was my 6th phone this solution seems to be the exception rather than the rule.
I did a lot of poking around on google trying to fix this and found a lot of people with different results. Try disabling t mobile sync and go to the myaccount app in the market and uninstall the updates. If that doesn't work try getting a new sim card and sd card, or just keep returning phones until t mobile offers to send you a g2x...
Also if you search around you'll see that this isn't just a problem with the mt4g. I found multiple threads where this happens on the nexus one, and several galaxy s phones. I really hope google is aware of this.

@johnsmith970: Thanks for the info. I will try calling TMO tonight and see what they say.
I am really bugged by this now. The phone gets totally unusable once this happens.

They will say to do a factory reset. Every tech support person I talked to told me to do that. This didn't solve the problem for me at all. It still exhibited the same symptoms on a fresh reset and not even signed in to google.
I would advise calling htc support just to let them know you are having this problem. Sending back a half a dozen phones per customer can't be good for anyones wallet or their peace of mind.

I have no idea why the stock rom doesn't like being rooted it's just what's been said and the solution which is most widely given (and mostly worked unless theres an underlying problem) is to flash a custom rom.

OK! I have more information for anyone interested.
I am tracking processes now in OS Monitor app from Market.
Most of the times it is the bluetooth daemon (bluetoothd) that goes bonkers. I was connected to my GPS in my car while driving, and when I came out of the car...the bluetoothd is going bonkers...looks like it may be trying to 'find' the device it was connected to. At the same time logcat2 process is also utilizing 30+% of the CPU.
I turned off Bluetooth and both the processes went away
So let me see if this sticks for couple of days.
Thanks

I wasn't even rooted.

If you want to keep stock rom this is what I did and its absolutely solid.
Install this stock rom:
http://forum.xda-developers.com/showthread.php?t=1042586
After installing this rom flash faux123 first time kernel. After its all booted up reboot back into recovery and flash faux123 cfs rc3 kernel. I have my cpu set at 1200mhz and everything is gravy.

[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?

@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?

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 ?

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] Turning off HTC Sense... Benefits?

Ok, So I searched through some of the battery threads and no one mentioned turning off HTC sense... So does turning it off and using just a simple launcher help with battery life?
For some reason my battery is being murdered, and I haven't done anything different. I am assuming my battery may be shot, but I don't feel like buying a new one, when I will probably be getting a new phone soon. I am, however, going to use some of the pointers I found in other threads, such as system tuner to under-clock my phone.
I have considered a system reset as well, have no idea if that could help, but may be worth a try.

I wondered the same thing.

If you qant tht, just use pyranid3d xe nosense version. Its no sense but still has all sense apps like music etc

Might be because the widgets and apps you're using are causing the phone to be constantly on. (i.e. Facebook refreshing every 15 minutes would drain battery faster as opposed to once an hour.)
Sense could be part of your problem, but it's definitely not your biggest one. I would attribute it to something like mobile data always on or something similar.

I think I am going to reset my phone, and go from there, checking everything is updating on wide intervals. Or not on at all.

Insanely high battery/data usage?!

I accidentally broke my Samsung last week so went back to my Inspire, good phone never had problems with it before. However I noticed that the Inspire's battery drained really fast now, where I'd have to charge it twice a day even if I barely used it. I assumed the phone was old and I just needed to replace the battery. Then a couple days ago I got a text from AT&T saying I had almost reached my 2GB monthly data cap (never even used over 300MB before) so I checked the AT&T data usage site and apparently every day my phone has been sending huge data files in the 30-60MB range multiple times a day.
I don't even know what these files could be because I haven't even downloaded any files that large. Phone is NOT rooted. Aside from updating Angry Birds, I haven't installed any new apps or added any new accounts lately, everything is exactly the same as it has always been. Restarted the phone a couple times to see if it was a fluke but didn't help. Had to completely disable mobile data for now.
Any idea what could be causing this? Any way to check exactly what files/data are being sent?

Check what has been using your battery up. In about phone-> battery. Whatever it is should show up there.

What I would do is completely wipe the device and start over. I really can't think of anything off the top of my head that would send that much data. It's possible its just bugging out and the Qualcomm snooper program is staying constantly active or something along those lines. Or you could uninstall everything and see if it goes away and then reinstall stuff slowly and see if you can pin it down to one app. That is a lot of data though. Not to cause alarm but you might also want to check the possibly of some sort of hack or virus that may have infected your device.

Yeah that might be the best thing to do (just wipe it all and start over), shouldn't be too hard to import my mail settings and contacts, that's all I really need.
How do you check for hacks/viruses?

I hard reset the phone, however when I synced my contacts back after it automatically re-downloaded all of my apps for some reason. High data usage is still there. So either it's a problem with an app, or the phone itself is just messed up. The battery usage only shows cell standby and dialer using it up and it won't show which apps are using the battery for some reason.

This is the HTC Inspire 4G forums. I would strongly recommend that you post in the Galaxy S2 forums. They will know how to answer your question better than us users of another phone.
