[Q] System process maxing out CPU

My HTC Evo 4G started showing the CPU maxed out via OSMonitor notification bar last night or this morning (I noticed it when I woke up).
I've done some searching on here and other forums and Google but can't find any solution.
The culprit in OSMonitor is very non-descriptive:
PID: 0, Process Name: System, Load: 85-90%
If I kill that task, then (as you might have guessed) my Evo goes tits up and reboots.
I've gone into "Running Services" and stopped anything that didn't look necessary. So there was literally only "OSMonitorService" and "Touch Input" showing and that made no difference. Not to mention all these services keep re-spawning after you stop them anyways.
I've also tried to turn on airplane mode (basically disable all radios) and it makes no difference. I do notice that for like 3 seconds, the CPU drops to normal, but then it goes right back up again. I rarely use 4G (thanks Sprint for dry raping me for $10/mo BTW)
I've tried Settings > Accounts & Sync > uncheck Background and Auto boxes.
I've enabled USB Debug mode as another forum suggested.
I thought it might be due to some market apps that got auto-updated, but I can't figure out how to find the last apps that were updated!!? The stupid market.android.com doesn't show you this information that I can find! Nor can I see in "Manage Applications" on the phone, a way to sort by most recently updated. I do recall seeing the notification that there were 4 updates, but none of them were anything I'd think that were "important" and all were apps that I've had for a while and have played nice before.
Android: 2.2
Baseband: 2.15.00.11.19
Kernel: 2.6.32.17-gee557fd
Build: 3.70.651.1 CL294884
Software: 3.70.651.1
My phone is rooted via Unrevoked, and has been for about two months now without incident.
Is there any 'strace' kind of tools that can shed more insight on to what this generic "System Process" is looping on? Or more importantly, what app is causing it, as I'm sure "System Process" is the symptom, not the root cause...
I'm about a hair-pin trigger pull away from putting a .40 cal through this POS out of frustration.

On a semi-un-related note, I rooted it for the sole purpose of being able to make a full backup of the phone. Something you'd think would be part of a normal routine that anyone (non-rooted) should be able to do...
So, if I make a TI backup, then format the phone (factory reset), can I selectively keep adding things from TI back into the phone to see what app might be tea-bagging me? Or is it an "all or nothing" kind of thing? Does TI pair up the apps AND the data? For example, can I restore an app, see if it maxes out the CPU, if not, THEN restore the data for it later (such as my shopping lists and aCar and other apps that I've invested a lot of time configuring)?
I've never had to use TI before and I've only had the Evo since the end of December.

Yep. You can restore apps one at a time and see what it is. You can also restore data separately.
Yeah that is what i would try if i were you.

You should try to flash a different ROM and see if this still happens.

[Q] JPF problems

Situational update: I am now running JPM. GPS problem fixed, but battery life is a complete nightmare: full charge during night, 8 hours later only 30% left (after 2 reboots because the battery dropped suddenly) with only 3G running.
I am using Quick Settings, Titanium, K9 Mail and nothing else. GPS is not on. Wifi is not on. What can I do? Also, phone temperature is rather high compared to 2.1.
Old situation:
Hi everyone!
Firstly thanks for all the info on the i5800, I have read a lot & come to understand everything better.
I am a complete n00b so sorry for any dumb questions. I recently upgraded my i5800 from stock 2.1 to FROYO.XXJPF as I had problems with the files of JPM (no .tar, no idea how to make them .tar) via ODIN. All seems to work well except three (important!) things:
- GPS doesn't fix, even with Octy's both apps & everything else I have tried
- phone temperature is through the roof, feels warm all of the time
- battery life is shortened considerably: full charge yesterday until 9AM, at 10PM is was at 10 percent with 5' calls, bit of browsing, 10' of tinkering with GPS. After reboot I had 30% battery life. I then installed CPU Tuner & still have 30% 12h later. Temperature is also down because of CPU Tuner when the phone is idle but when I start using the phone it heats up quickly again...
GPS is a big thing for me, so too is battery. Anyone any ideas? Typical JPF issues?
Also, when I did the upgrade to JPF, I had an /esf backup, app backup & contacts backup but all the rest was gone afterwards... Is there any way to keep app settings (e.g. email account settings, ...)?
And, is there an alternative to ROM Manager that does work for our phones?

Try out the Custom ROMs...Kyrillos ofc.. the best stable version out there!
if u have problem about this ROM...just PM me...

Hi,
First of all I would advice to install JPM, not JPF. The rar from samfirmware does have a tar inside and it can easily be flashed using ODIN. The link and instructions are on this page:
http://forum.xda-developers.com/showthread.php?t=778880
Also don't restore any backups after flashing a new firmware, you may be creating version problems restoring files that are meant for another firmware.
If you want to backup your contacts just export them to a .vcf file in the contact app and import them later from the file after flashing.
Finally, do a factory reset and wipe the cache before and after flashing.
So shut down the phone, hold home + vol.up + vol.down, turn on, select factory reset from the recovery menu, then select wipe cache.
Then shutdown the phone, hold home + vol.down, turn on, connect usb to computer. Flash with ODIN.
After flashing do the factory reset again with same method as above and after reboot import contacts from .vcf.
That should give you Froyo without any problems.

Thank you both.
Bakayoyo, I just followed your instructions and am now booting a factory reset/swiped cache JPM. I will report back! Thanks for your detailed & clear instructions, that makes everything a lot easier...
Lastly: I keep having the issues with the JPM download via the XDA-thread. Via the Samfirmware website there is no problem... The download there is just a .rar that unrars to a .tar package.
EDIT: GPS is functioning. Will report back for battery life & temperature. Thanks a million, Bakayoyo!

Ok update time. Battery problem still occurs: full charge tonight and at 60% after 5 hours with only 3G running and nothing else... I had adfree installed, threw that off. Now only Titanium, K9, Quick Settings running. What to do and what is causing this? Phone feels hot too...
EDIT: see first post, now at 30% by doing nothing, only 8 hours after full charge...

It is better if you use task killers. I am using jpm and my battery is fine gives me a whole day even with 3g. Apps running in background consume battery.
Sent from my GT-I5800 using XDA App

I did some research and found out I probably screwed up with settings in K9 as I had push accounts poll every minute...
I have 3 push accounts that are now only pushing and 1 POP account that is set to poll every 5 minutes. I'll see what this does to battery life, as I did not even get 12 hours of only 3G before it fell out today.
I read a lot of warnings on ATKs on 2.2...

r u sure? i dont think so... if u kill apps running on background, they will reload later again itself. and killing and reloading apps all the time is consuming battery

Well when you use apps like facebook,music players,video players etc. They run in background even when not needed to. For backgrounds services you have task killers which have options of not killung these services. Personally i kill each app and service. Due to this my battery life has been extended by a whole.

Try InDroid 3.0 . Any version.(There are 4). GPS Perfect! About battery life , User review is enough.

GPS is fine since JPM.
Battery was being eaten by K9, even with correct push settings. I uninstalled it, and went back to standard email app. Result: phone temperature back to normal, battery life back to normal. So all is fine now! Only issue that remains is that incoming calls screw up the battery meter, reboot fixes this (this was already an issue in stock 2.1). Very annoying!

I couldn't go to 100% since RC2..2g/3g bar widget seems to work ok for me...

battery % is a safety issue so your battery doesn't over charge and explode. If you insist on having a 100% charge, when it says charged but is only at 95% (or more commonly 97%) unplug the phone and plug it back in and google trickle charging to get a good idea of why this happens. 2g/3g toggle has been an issue for lots of people since early on but most are reporting that it is working fine for them now. May be time for a good total wipe and fresh install. I found that not using titanium backup for my apps has improved the performance of my phone pretty signifigantly. Just be sure to backup all your saved game data and reinstall all your apps the old fashioned way.

You're sort of right about the charging issue, technically the phone STOPS charging at a certain percentage. The issue with trickle charging is that it doesn't stop charging. The issue is that the phone should charge to 100% then stop and start up again (for example on the Evo it drops down to 90% before kicking back in) however the Nexus S after 2.3.3 charges only to 97-ish%. This is not how it is supposed to happen though I've not seen anyone who was adequately able to explain why it was screwed up in the newest update.

Only thing I can think is to let your phone charge all the way down till it shuts off and then charge it back to full while turned off. This has helped me in the past.

I recommend only backing up user apps + data, as backing up system data sometimes will give you problems. Once in TB click you setting menu and sellect batch. Now click the option that says backup user apps +data and confirm. Now when you wipe your data in CWM and do a fresh install just install TB from the market and use the same batch menu but instead of backing up user apps + data use the restore user apps + data option.

So check this out: Titanium Backup was giving me trouble. Maybe six or seven apps into the backup, it would freeze, and then reboot (RC2, RC3, AND RC4). After a few reboots, the phone turned back on and said that the SD Card was unreadable and that it had errors, I rebooted it with a few swift battery pulls and all is good. In closing: I successfully backed everything up.
Now, I still kept getting reboots on RC2, 3, and 4. I could not think of why, and then it dawned on me, that it's probably the kernel I installed for BLN and 1.4GHz overclock. I installed h14-blnV4-vs6-cm7.zip.... Could this be the reason I am getting reboots? Because in SetCPU I changed it from 1400MHz to 1000MHz ondemand and I haven't yet come across a reboot. So, it could be the kernel and not CM7, RIGHT??
And if that's the case, is there a better kernel out there? or should I just be careful when overclocking?
Thanks

Same problem here, it totaly kills the radio. Reboot doesnt help only reflash helps.

[PSA] Removing bloat may make battery life *worse*

Just one data point, but it seems like a very clear takeaway:
I used titanium to uninstall a bunch of social apps, specifically anything including the words
facebook
twitter
flickr
instagram
linkedin
picasa
Importantly, I included any related apps (eg "Facebook Engine.." "Facebook for HTC Sense" etc)
I also uninstalled Car.. and HTC Car..
I found to my surprise that battery life got worse.
Much worse.
I ran the phone like this for two weeks and got somewhere between half and three-quarters of the battery performance during a normal day's use. A key observation is I went from losing 1-6% battery capacity overnight to losing 20% every night.
I restored a nandroid backup (returning the phone to its state immediately before removing these apps - - I made the nandroid for this reason and only this reason, and removing the social apps was the only change I made to the phone after making the nandroid) and my battery life immediately returned to normal. The last two nights since I made the change I lost only 2% battery life instead of 20.
Again, this is only one data point, and it's *possible* some other random thing happened in my world that could have caused this. But I really earnestly tried to be scientific (and patient) about this, and to me at least the result was very VERY clear.
Just leave the social apps, even if you don't use them.
[NB- I always remove 7digital, kidmode, rescue security, and I sometimes remove Chrome, and have never noticed an effect on battery life after removing those apps, over many months of owning the phone]
PS I don't have the paid version of TB, so no, I didn't freeze, I uninstalled outright and was forced to nandroid back to get to where I was before.

That sounds very strange!?
well, anyway, those apps, how much space are they taking from storage?
i feel i dont need to remove any apps, have plenty of room.

Just disable them under apps, and the hide the rest with whatever launcher you're using.
Battery life was fine for me (when I ran stock), and it's fine on my gf's one (who is currently still stock)

I remover app bloat all the time and get better battery. Are your sure your not doing it wrong?

Just selected the app in Titanium and clicked "uninstall". You tell me - is that doing it wrong?
I don't think this so much about *how* to uninstall an app but rather *whether* to uninstall an app that other parts of the whole system are expecting to be there.

Usually bloatware is installed as a system app. Sometimes when you uninstall them you can get some weird wakelocks or FC's. I usually freeze the app. Delete all data then uninstall.

This is true. Get an app like BetterBatteryStats and it will tell you if there is anything causing excessive drain. I have personally never experienced worse battery life after installing social apps.

That's crazy talk. Its definitely all in your head...

Experienced similar thing too. Tried several "debloated" ROMs like Trickdroid, Orio, few others (both when they were 4.2 and now leaked 4.3) and had an awful battery life. Went back to 4.2.2 stock (2.24.401.8) and now I can use my phone throughout the day again.

Well, what's being discussed here is taking a virgin stock ROM that has been running happily for some time and then using titanium to uninstall all the social apps at once: this method may cause wakelocks.
A ROM that has had all the "bloat" removed in advance before you even flash it seems less likely to leave your phone in such a state?
I'm not saying your experience is not real, and it raises an interesting point, but it still seems to me if bad battery life were common to all those debloated ROMs, I think we'd have heard more about it by now?
The right way to really test this, which was suggested above and I'm sorry I didn't do, is install BBS or GSAM and find out *what* is eating battery.
All I know is
- I changed X
- Things got worse
- I undid X
- Things got better

Now to test again remove the bloat again and see what the battery life does. But it's good you actually did some testing unlike the people calling you crazy but if your battery life decreases again after repeating the experiment the results are much stronger.

i remove all bloat that i would never use and my battery is fine

When I was stock, I froze everything that I considered to be bloat. I typically don't uninstalled system components. There's always a chance of borking something by uninstalling something you shouldn't have.

I'll uninstall carrier apps, because those are added after the fact. Uninstalling system apps can definitely cause issues. Better to hide them like someone suggested.

Huge battery drain

I bought the mi A1 about 8 months ago and it was working fine up until 3 weeks ago.
The battery has started to drain big time and the Android is consuming most of the power.
I've tried the below already,*
1. Calibrating my battery.
2. Factory reset to January update.
3. Stopping the apps running in the background.
4. Turning off location / wifi and internet.
5. Tried disabling backup of photos.
6. Disabled app preview messages under Google.
Despite doing all this the battery drains big time, even when it's idle when I'm sleeping.
P.s - I'm unable to upload screenshot because it keeps saying that there's a network issue. But the screenshot stats say that the android os consumes most of the battery and SoT was 30 minutes. Phone was idle for most of the time. It came down 100-20% in a few hours.
Android OS is eating away most of the battery.

First thing, clear the cache, you can use explorer to do it, hit clean at the bottom.
Check running apps (settings > developer > running services) and see what is running and using battery.
It might be the media scanner, they use loads of battery when they get stuck on a corrupt file, you could take out the sd card if you have it formatted as external.

Thank you for your response.
I've cleared cache using the Files Go app.
I checked the services running in the background and I've all the cached process but they seem to be regenerating.
Apps consuming RAM are - Settings, Messenger, callenhancement, SimContacts,com.qualcomm.qcrilmsgtunnel, carrier services, google play services, spock, swiftkey and the launcher.
All these get regenerated even if I kill them.
Do any of the following cause battery drain? If yes, how do I fix them?
I've already done a factory reset but the problem still persists.

Apps will start and run in the background, that is normal in android, the only way you can reduce that is to reduce the background apps in developer options.
I think you should instal better battery stats which should help you work out exactly what is draining the battery.
Is you phone stock, have you rooted, used any custom roms or modded it?
