Suspend Process using lots of CPU

Hey all,
Noticed my battery level dropping pretty quickly even with SetCPU etc. underclocking my Desire when the screen is off. It seems it's the Suspend process using around 30% CPU for no reason. See screenshots attached.
Any ideas what could be causing this?
Thanks
Russ

It may be that System Panel itself is causing your issue.
See this thread.

Dave

Having it simply installed would cause this? I don't usually leave the monitoring running unless I suspect something is up, that's the only reason it's running at the moment.

Probably not, but it may be skewing your results when you try to determine what's causing the problem. What about partial wake locks - is anything else keeping the phone from sleeping?

Doesn't seem to be anything else. I'll keep an eye on it now that I have changed the priority setting on system panel.

It's definitely not SystemPanel. I have it and it's off and the suspend process is running wild.

Did you ever find out what was causing this? I'm finding the same thing on my phone twice this week.

turn off auto sync, toggle on off as needed, you can be running all sorts of data through system apps via 3G even when the phone is asleep/standby

Foxmeister had a point because suspend does show up as 10-30% consistent when you have hardware monitoring and logging enabled in many apps like System Panel.

this isnt it. i had my phone in airplane mode all night and the "suspend" process started running at 10% CPU from 10pm to 6am when the battery died. if airplane mode was on the whole time, no way its caused by data/network

I am having the same issue, airplane mode was on but suspend is acting crazy. This has been killing me since I've flashed the new update for evo 4g for my rooted phone. 30% sucking from process has left me charging my battery twice a day. Please help if anyone can!

same issue here.
EVO ... Froyo 2.2
suspend ... according to watchdog ... is regularly registering at over 50%...
if i reboot the phone .. it will take care of the issue for a few hours or maybe a day ...

I'm having this problem too. Rooted with Myn's Warm ROM. Someone at AF said it was the Facebook app. I'm uninstalling that now...
...any other ideas?

Same problem. Rooted evo king bfs #9 kernel

I have "always on data" un checked and noticed this... Maybe apps are trying to sync but have no network connection...

Was having same issue with rooted stock rom. Recently flashed to Vaelpak 2.2 and hasn't happened yet...

So this still happens to me once in a while. I found if I'm in an area where I can connect to wi-fi, the suspend process drops to 0, after connecting to wi-fi. Other than that only a reboot will "fix" it for a while.
Anyone else have any updates?

I raised the flag on this issue in early august for my stock 2.2 EVO. I was basically ignored back then, so now that others are experiencing this, perhaps we can get enough info to submit to HTC for a fix. If it's affecting the EVO and the Desire, it probably affects all 2.2 Sense UI androids.
http://forum.xda-developers.com/showthread.php?t=759301

I'm in the same boat... I never noticed this problem, until Sunday. Now I have had the problem 3 times in 4 days. Reboot fixed each time, but seems to be coming back more often now.
I'm running VaelPak 2.2... Maybe gamer83 is onto something with it being Sense related /shrug...Has anyone running CM noticed this issue?

I am experiencing abnormally high suspend cpu activity too. The strange thing is it behaves when I am connected to a wifi network. It goes to crap when I am away. Not sure if means anything, but when I am away I have 4G on.

[Q] Internal system full message

I'm running ef02plus. My epic will sometimes go out to lala land and reboot or just become unresponsive. Sometimes the battery will drain within 5-10 minutes. It has always been a little unstable no matter what rom or radio I had installed.
I opened a shell window to find out where the space was being used and found that in /data/data/log (I believe if I remember correctly) there was about 200mb of what appeared to be core dumps from apps and system processes. I removed the files and resolved the problem for now.
Is this common? Think I should go back to stock and do a switch out? It's been annoying but I've put up with it until now.

Why don't u go to a newer gingerbread rom ef02 is way outdated

Hmmm...I'm just one leak away from current. I didn't see much in the way of improvements?

I froze DRM launcher with mytoolbox and turned off auto sync. I've read a few posts that low signal areas can cause the battery to get hot when sync is turned on. Will try that for a few days and see how it performs. Battery life already seems better.

EG22 is much more stable than EF02. Those reboots and lockups that you speak of occured constantly for me on EF02. I have been on EG22 since the day it came out and I have not had a single lockup, force close or reboot.

[Q] Wifi and cell Reception stop working after screen is shut off?

When I turn off the screen of my phone, I lose my wifi and data connections. The icons of them in the status bar turn white rather than the usual green. The only way I have found to fix this is to put the phone in airplane mode then take it out. Which is really inconvenient EVERY time I want to use this. I know that when the WiFi turns green it means that the phone is connected to Google. But it never goes back from white to green even after I let it sit for a few seconds and try something to push data through. Even when it's green it doesn't work until I reset the radio.
Things to know:
1. I am rooted.
2. It is the AT&T LG Nitro HD (LG P930)
3. It is the V10f software version.
4. I have not tried a factory reset yet because of the hassle. Yes I know about titanium, it's just time consuming.
If anybody else has this problem, please let me know. Hopefully we can get this fixed.

Update: I fixed my problem by installing Wi-Fi fixer. But it still makes me mad that this occurs. Maybe we can try to find the source of the problem.

Maybe you are running some battery saving app like juice defender? Check the settings there.

Nope, I'm not running juice defender. The only task killing app I use is Advanced Task Killer which I only ever use when I need to quickly restart an app, I don't use it every 10 minutes like some people do.

I had a weird incident where I lost my wifi radio...wouldn't detect any wifi ssids...don't know what caused it. But your situation seems similar...sadly I have know idea how it got fixed...rebooted phone a couple of times and haven't had a problem since.

Sleep Of Death

I don't know if this possible but I really like to find out if there is something causing the SOD that we can actually do something about(as in it isn't hardware causing it). I get SOD's on some repack kernels but not on others. When I get it has quite frequently. I am not running setcpu nor do I have any other software controlling the cpu. I have however been using juice defender. I like the product. I am going to remove it and flash a repack kernel that I know gives me SOD's and see if something in the power saving on the JD might be contributing to it. I would like to hear from others that have this issue and see if you are running anything like setcpu or JD.

I've been thinking of something. I don't have sod at all. For those that do have sod how good is your phone at overclocking? Meaning can it run stable at like 1.6 or where does it freeze at?
I'm wondering if its something to do with the difference of processors.
If anyone needs any help with the epic touch hit me up on Gtalk @musclehead84

I dont really overclock anymore but when i used to, my phone froze at 1.6. This was back when i was on calk eg30 rom. Idk what would now if i tried again
Sent from my SPH-D710 using xda premium

I haven't oc'd mine so I am not sure what it is capable of. Tomorrow I will disable the JD and flash a repack and see if that has any effect. It is frustrating because I love the repack rom's. For now I use mobile odin to flash a repack and boot to recovery if I want to nandroid then flash the stock kernel back again.

I had it until I updated modem, and when I say had it I mean right after flashing an ics rom, and every time after the phone sat with screen off for more then a minute, can run at 1.6 no problem, don't see a point though

I was just curious because on the original epic I had sod on some kernels and that phones processor was terrible. It froze when I tried to overclock it. The next one I got I wad able to overclock and I never had sod. Just seeing if phones with not being able to overclock might have an issue right now.

Are you using SetCPU? If so, don't fix screen off at 200-500.

Yeah we really meed to figure out what the heck is going on. For the last few days i've been trying to figure out why i've been having SoD. Im on blazer ROM and ive found out that if I don't flash a new kernel i'm fine. But as soon as I flash rouge 1.4.1 or 1.4.0 I get an onslaught of SoD. Things ive tries to fix it are:
-Installing set CPU and raising the voltage and changing gov. to on demand.
-taking all the init.d scripts out of the blazer ROM zip before flashing.
-I find that when the phone is on the charger it never gets SoD
That last point leads me to believe that it has something to do with deep sleep. Because when the phone Is plugged in it isnt allowed into deep sleep mode and idles at 200Mhz. Ill be looking into this more tonight. If anyone would like to work with me i'm always in the e4gt ics dev channel on freenode.

Do you run Juice Defender or any other power saving app? I am on an ICS rom and when I flash the repack, almost everytime I power off the screen I get an SOD. I am getting ready to disable JD and flash the repack and see if that makes a difference.
UPDATE: I disabled juice defender and flashed the repack. Have gone for 40 minutes without an sod. I am going to enable the jd but change several of the settings to see if that will allow me to run it with the repack and not get frequent sod's

you know....oddly enough I did install juice defender a few days ago....then flashed the 1.4.0 kernel and thats when everything started.....BUT ive since reflashed the rom a million times without re installing JD and i still get SoD with the 1.4.0 kernel
If you continue to not get Sleep of deaths...will you try flashing 1.4.1 or 1.4.0?

Just to clarify, does the SOD issue include texts/calls not going thru whatsoever while phone sleeping on or off charger for more than ten minutes? I get this with any ICS up to 06, when people call me it goes to VM directly, texts go to sprint limbo. Or, do these leaks just horribly handle low signal areas? I was on stock 85 prl, and signal was about 0-1 bar sprint and force roamed on 1xrtt for 2-3 bars... since this screwed me on a couple important calls I reverted to EL29 and flashed 111115 PRL... anyone have these issues with ICS, or is it just my **** reception and network issues?
Oh, and I SWEAR... no conspiracy theory... but anyone notice pretty much all samsung leaks have issues that are magically fixed for final release? Epic froyo, GB, now ICS on the Epic Touch... just sayin... its like they dont want us daily driving these... just use em enough to beta test (really this site should be renamed XDA Beta Testers)?

The issue you are talking about sounds more like the loss of service bug that has plagued some of these phones. the sleep of death is when the screen turns off and then you can't get the phone to come back on with out holding the power button for 10 seconds or pulling the battery. I am still doing fine. I enabled juice defender but selected advanced settings and disabled jd from controlling the auto sync. I set the controls options to default. So far I haven't had an sod. I will see if I can flash those repacks but I am not sure if it will work right since I am on an ICS rom.

SoD almost certainly involves the cpu going into deep sleep and not coming out. I have never experienced this issue on the E4gT on any rom/kernel combo, but I dealt with the issue extensively on the nook color it it's early days. I can definitively say that because a large number of users are using the repacked kernels and are not having SoD issues, then it is 100% NOT repacked kernel related. SoD is caused by voltage issues or cpu step switching problems. The repacked kernels are identical in these regards across all users, therefore the repacked kernels are not causing the SoD issues.

I've had the SoD a few times on FC05 and FC06 - I'm in the process of downloading FC07 right now. It doesn't happen often (3, maybe 4 times in a few days) and I cannot pinpoint any actions preceding it. I no longer have Juice Defender installed. It's odd though, I've also had problems receiving Kik messages after a reboot. My girlfriend sent me a few messages 6 hours ago that I didn't get until I opened the app, then it's back to normal. This is a pretty regular problem. It's like I have to kick start the app before it starts. But over that 6 hours I streamed Pandora just fine and Gmail has been syncing as normal.

It is a puzzling issue. I also don't think the repack kernels acutally cause it to happen but there is something about the issue that causes it to happen frequently when using a repack. I can go back to any of the stock kernels and it works fine even with juice defender running. That is why I thought perhaps it was some app like juice defender that was causing it but people still have the issue without juice defender. Fortunately for me it seems the fix was to disable juice defender. Unfortunately for my battery though.

Well so far it seems that ive found my solution. All i did was grab the 1 click Odin to Stock Rooted EL29 and wiped everything. I wiped internal storage and flashed back to rooted stock with odin. Then i Odin'd a kernel and flashed back to blazer rom and then had to re odin the rouge kernel that was originally giving me issues. So far all is well. I suggest giving it a shot

WiFi crashes after phone goes to sleep

Hello,
I have recently factory reset my OP3 due to a battery drainage issue. Google play services started using around 30% of my battery and consequently my SOT decreased by a lot.
After the factory reset, I freshly installed of all my old apps, and I downloaded my photos from the Gdrive.
Unfortunately, since then my WiFi is acting strange. Whenever I start the phone, the WiFi is performing normal, but after a while my phone goes into deep sleep and my WiFi disables itself (just like i configuered in settings). However, when I wake my phone, my WiFi won't turn on and when I go to the WiFi settings the phone becomes extremely laggy.
I have already wiped my cache again but I don't know what else to do.
Any help is appreciated!
Kind Regards,

Same strange problem here,I must reboot phone to connect wifi.
I trying with 3 kernel, it's not kernel problem.

It's such a strange problem. I don't understand why this problemwould occur after a complete factory reset...
I had the same issue a few years ago with my HTC One M7.
By the way, my OP3 is completely stock running Android 8.0

Same problem with my 5T on 5.1.1. Weird thing is I haven't made any changes, just updated a few apps but none of them should be causing wifi issues and settings (battery history) to lag after sleep.

I have set wifi to always on and don't have this problem. May be the doze feature is affecting it in your case. Why don't you try the always on setting? For me it doesn't drain the battery also. So no harm in trying it.

And why settings not responding? I must touch home button in order to have working settings again.
I think it's Oxygen Os problem.

The problem does not occur if I set WiFi to always on. However, this uses way more battery in my case.
If i set WiFi to always on my sot decreases from 4-5 hours to 3-4 hours.
EDIT:
I also can't find this issue anywhere else on the internet.

Can't find anything either. You have any of these apps installed? Substratum, Microsoft Remote Desktop, Twitch. Updated these apps two days ago which is when I noticed this problem, haven't change anything else really. Updated router firmware too (Virgin Media).

I can only think of factory resetting again and checking the behaviour of wifi before installing any other apps and downloading photos. Then you will know whether an app or the downloading is the cause and take action accordingly.

No, I haven't installed any of those apps. However, since the factory reset I started using the regular Chrome instead of Chrome Beta.

I think so, yes.

I just disabled all third party apps, and the problem still persists

I have set wifi always on,and flash HolyDragon kernel, problem it's gone.
I don't know if kernel, or settings always on wifi, resolve my wifi connection.

I've been having the same problem too as of yesterday. Did a factory wipe and reinstalled Oxygen 5.0.1 but still having the issue after i reinstalled apps. going to try a factory reset again and not install or update any apps to see if maybe a recent app update is causing this.

IT didn't work for me. Right after flashing the OS back onto the phone and connecting to WiFi, i changed the WiFi setting for "Keep WiFi awake when asleep" to "only when plugged in" and after locking the screen and waking it back up a few minutes later it still wouldn't activate the WiFi; I had to manually go into the WiFi settings and turn WiFi back on.
On the bright side though, I did do some reading on the "Keep WiFi awake when asleep" setting and several sources said to leave it on "Always" since it actually drains more power turning on the WiFi radio when the phone wakes up. I've since changed that setting to Always and over the last two days I've noticed slightly less battery drain!

It happen to me too. Cant turn on wifi after waking up from deepsleep. Must reboot the phone. I had tried to clean everything , data, system,cache, everything and made a clean flash but it still happen ,only for 8.x android. I tried in Nougat and see no such problem. Im using oneplus 5t

Yea, I have same problem staring with oreo update. Can say, that I tried all kernels around, and some of them made wifi connecting faster or even reduced the number of crashes, but not completely. Sadly, I can't stay on those kernels, coz I have another problem, - iv got random reboots with most of them, only stock works... So every solution is inappropriate for me, and I reverted to nougat waiting for Android 8.1

Same problem here. I am on beta 35. Additionally I was on Franco kernel and had random reboots. Kernel back to stock no more reboots but still the wifi issue. I'll test the always on.

Hopefully it gets fixed in the next update. For now, I'm using the ''always on'' WiFi option.
Thank you all for the replies!
