SetCPU widget stops updating?

As the titles states, I use the SetCPU widget and find that it stops updating after a while (after which, I'll have to remove and re-add). Is there a fix for this?

That has been happening to me and I haven't found a fix. I just stopped using it. It's a shame too because I used it a lot for checking the temperature, making sure I wasn't running too hot.
Maybe you can try reflashing the kernel.

did it on every rom even stock i have used. i stopped using setcpu, it caused more problems than good

confirmed here too, the widget stops working for me after it's been on charge for like an hour. The status bar/notification bar icon works though (but no temperature)

its the app and the widget itself, for the longest time i had this problem when i was using my n1 and running cm6 and not only that, when i had it set to a certain freq. i go back into the app and it would say its clocked at 800 max, but i had it set to 110, i would have to adjust the freq bar to set it back to that.. i email the dev bout it all he said it was not set on boot, which i replied thats no the issue on hand as the phone has been booted up for awhile, and i manually set my OC, i never got a reply back after, so i check set on boot, and after bout an hour.. i go to setcpu and same issue
my target is set at 110 but its saying its maxed at 800, this also set on performance to always be on that OC, i told the dev again. and still no response so i gave up on setcpu, and glad the Cyanogen made built in cpu govnor

Its the widgets, my data signal widget takes a crap and freezes too. Setcpu works fine even when the widget freezes

If running cm7 just use the built in settings. I used setcpu with off screen prifles being slower and others but it actually made my phone run like crap. Battery life has been generally the same without using setcpu so I killed it. If u are running cm7 I wouldn't bother with it.
Love the Overclocked "nonsense" CM7

Voltage control settings?

I'm on sfr 1.2 with genocide 1.1 final kernel, what are optimal settings for voltage control for speed, everytime I put it at 1.4 it instantly freezes and I have to pull battery, then when I put it at 1.3 it will be fine foor a little while but if I multitask like using music player the phone freezes and I must pull battery again, what should the speed mhz and voltage be?

First of all, this topic has been touched on before, but I will give you a quick rundown as long as you promise to read the "You are new to XDA post" in the general forums.
Every phone is different, which is why Voltage Control is so awesome. You can "feel" out each phone's "max" and "low" and set it accordingly. If you are just using the first page of VC, set the max to 1400, min to 200 and leave the dropdown menus where they are (mine is on cfq and conservative, but I can switch between the others with no problem). If you keep the min at 100, you almost always have problems.
Also, try doing a completely clean flash. Boot into CWM, wipe everything three times (sometimes I do over-kill and go 4 or 5 if I am feeling froggy or have nothing better to do) and then install ROM, then Kernel.
If this does not help you, then you can only run at 1300. Unless anyone else has any ideas. *shrug* I am still n00b.

Or 1200. Every phone is different. I personally can't go above 1200 without near-daily issues like abnormal freezing, lag, and overheat. But like I said, it's all phone-to-phone. Play with the settings when you're bored and have a recent nandroid backup. Same goes for undervolting, though I don't bother with such. There's much more to potential consequences of undervolting than what you'll read in many of these threads.

Also, music and video tend to push the phone the most. A good way to test if 1300 will work for you is to run YouTube, play music, etc. Always set "apply for now" as well until you know your settings are rock solid. If you select "set on boot" and lockup or freeze you will most likely have to wipe everything and start again. It takes some people days to get Voltage Control just right especially when it comes to undervolting. Test every combination of the apps you use the most.

Major battery problems

I observed my battery first with regular use (mainly just twitter and texting, not much gaming or data usage, ie. YouTube) and I find that the battery drains about 10%~hour, or maybe even more.
Right now I'm in Buffalo and I put the phone airplane mode so I won't get charged with receiving texts (data off means better battery right?) but even with data off, I still get crazy battery drains. my phone needed a charge at 15% and it hasn't even reached 10 hours on battery, and most of the time, my phone wasn't being used. Am I doing something wrong?
Here is my settings:
- Stock rooted Bell ROM
- Faux 013u Kernel
- OC Min/Max: 1ghz/1.8ghz
- Brightness: Auto
I can't really thing of anything else that may affect the battery a lot. :/

Unless your doing gaming, which by your post, your not...why do u feel the need to over clock? Try under clocking. Hell I under clock to 800mhz and notice NO performance decrease, other than the browser not loading pages as well.
Few suggestions;
When using a tw ROM give the power saver a go
Don't over clock. That was cool in like, the hero days lol
Try out aokp, I get the best battery life with aosp ROMs....no tw crap to bog it down
Use auto brightness
Turn vibration off
Use CPU spy to ensure your phone is sleeping properly

Well, occasionally I do play games which by my experience run much smoother with OC. I use setcpu and I used the screen off profile and make sure the CPU sits at around 700 MHz, and I'd expect that to help (which it does a bit), but it doesn't help with the overall problem.
Now with your AOSP suggestion, is it safe to flash it on a Canadian I747M? (As in, I wont be getting random ATT Device Manager registration crap, etc.) Which ROM (+ kernel) would you specifically suggest?
And with the whole gaming thing put into consideration, I'd like to keep the OC since I like smooth games, but is there a way to counterbalance that for battery? Undervolting, CPU editing, etc. All the help would be greatly appreciated.

Lte hsdpa switching may have caused the problem.
I got this problem occasionally but not once after I disabled lte since last week.

Loose the kernel...trust me on that use toonz I'm ocd 2.1 and still get 20 hrs
Sent from my SAMSUNG-SGH-I747 using xda premium

also what is your signal bars like before airplane mode
plus it seems like you have a rogue app.

Why is your minimum soo high? Keep it at 384 or switch to Ktoonz kernel and go down to 96mhz. You can also lower your voltages to save battery.

Well, if there is the possibility of a rogue app, the only Alps that I could think of would be LightFlow along with SMS Popup.
But is my screen usage normal? 70% is a bit much no? Or is that just me?

[Q] Phone getting hot after few minutes of use

Been noticing this since last week. Every time I use my phone for like 1 or 2 minutes, the phone starts getting hot. Usually, it gets hot after an hour of use (Facebook, Messaging, Browser, Twitter, Play Store). Went to Performance settings in Settings, then Processor, and notice the Current CPU frequency is always at 1000 MHz, then goes down to 200 or 100 MHz when idle for a few seconds. Switched between conservative and ondemand governor, no OC. Was on PA 2.54 when this happened, but I'm on CM10 Stable now, and it's still getting hot after using it for a few minutes.
This hasn't happened to me before. Not sure if this is normal, but I just want to make sure.

My recent heat and battery drain was coming from an app. I didn't check the CPU.
I checked the battery area of the settings and found a locale add-on that was draining more juice than my screen.

It will happen if your signal is real bad or 3G is down in your area.

I don't think it's my signal. I get 2 or 3 bars almost all of the time at home with the FC09 modem.
Besides opening and/or using an app, it seems that the CPU clock will go max speed if I do something, such as scrolling. Battery is also draining quickly before this was happening to me.

I think that's a Jellybean-specific CPU behavior (to keep system flowing like "silk", JB put CPU at max the instant you have your finger on screen... At least that's what I heard). Try ICS/GB ROMs and see if problem persists.

Yeah, you're right. I even looked it up. It's part of Jelly Bean.
I'm going back to CM9 or The People's ROM.

You could try a different kernel, or lower voltage. Sorry not sure what phone this topic is for lol but that's some options. It takes a lot to get my phone hot, and I'm on jelly bean

You likely have an issue with your settings.
If it's not an app, you probably have an issue with your performance settings.
Try turning off some of the eye-candy features in the settings. This will likely include the Cyanogenmod specific setting area as well.
That should at least help.

It didn't help unfortunately.
I flashed CM9 earlier and the issue still exists. I'm now back on CM10 (11/22 nightly).
It's okay if this can't be resolved. I am probably gonna go back to a GB ROM.
EDIT: Issue still persists in GB. I'm guessing it could be a hardware issue? I have no idea. Back to JB. I'm still willing to try anything to resolve this. Thanks to those who posted some solutions.

Cpu problem.

I'm running jmz stock rom, no problems, but recently I've seen that my Cpu voltage has been kept at 1.4 (full over clock) and it won't come down unless in deep sleep. I've tried Cpu control apps, they don't seem to work. Not sure what the problem is.

did you change the cpu governor to performace?

govenor is set to smartassV2. ive tried changing it to all of them, when the screen is on and the phone is not in deep sleep, it is running at full speed for some reason.

that used to happened to my inspire 4G
i had to reset it . that usually fix it .

i wiped, reflashed, whatever there is i can do and it STILL is running on max cpu frequency. it makes the phone very hot, and uses quite alot of battery throughout the day. better battery stats just says that system is using the most, and that 1.4ghz has been running 100 percent of the time (unless screen off ((deep sleep)) )

if i remember correctly , it was an up doing it to my phone ,
you said you wipe and reflashed , did you installed the same apps .
honestly i dont see why using battery stats.

problem still persists, not sure why though. seems when i restart it sometimes it will do it, and other times it wont. Usually waiting for the phone to cool down, then restarting it fixes the problem. Not sure why.

Flash jmz linaro kernel and use any app to lower the cpu freq. That's how I have been using mine since v1. No heating or draining issues so far. I use smartassv2 as governor.
