It is best not do use task killer.
Those tasks will come back after you killed it and resulting to battery draining issue.

Saw someone posting as below:
Seems like make sense also.

YouTube is in no way a reliable source of information when it comes to technology. Unfortunately, neither are these forums, as witnessed by the masses of people that consistently state underclocking saves battery. I've posted about this several times before, and it seems no one ever listens or trusts me, so I'll try to lay it out as simple as I can. This effect is very well known by old school Linux nerds that would push their notebooks to get longer battery lives. Intel calls this effect HUGI -- Hurry Up and Get Idle. It essentially states that the faster a CPU runs, the more energy it consumes, but it *also* finishes it's work faster. Finishing work faster is important as it means that the CPU can go back to it's "Idle" state faster. The idle (or sleep) state uses virtually zero energy. Let me see if I can pull up the voltage table for a phone... here, found this for the Sprint Nexus S 4G and it looks to be accurate based off my memory of the CPU.

1000mhz - 1.25v
800mhz - 1.20v
400mhz - 1.05v
200mhz - 0.95v
100mhz - 0.95v

Now, let's say we have a task that takes 10 seconds to complete at 1000 MHz. 10 seconds times 1.25v is 12.5v (I know, I know, voltage doesn't work this way -- but it's a good enough approximation to demonstrate this effect (and it's to scale!) and I'm too tired to explain volt vs amp vs watt, it's 5am here). At 100 MHz, though, the *same exact task* would take 100 seconds! 100 seconds times 0.95v is, wow, 95v! By capping your CPU to 100 MHz (10% of max), you are effectively using (95/12.5=) 660% more energy to do the same task.

Now, there are scenarios where underclocking can help you, such as when your phones CPU is running at 100% 24/7 because of shitty applications or leaked wakelocks. Although underclocking does appear to somewhat fix this, it's a complete ****ing hack and won't give you anywhere near the amount of battery life that you'd get by uninstalling the shitty app and letting your phone go to sleep.

Uncle, need help here. I flashed my note to Rocketrom v22 but my market is not updated. furthermore when i wanna update the apps, an error "package file was not signed correctly"

The best part is mine is still google market instead of google play.
i think that is the reason why and i can't get the google market to be updated.

I have been checking from the net and no solutions.

"Package file was not installed correctly" error
If you receive the "Package file was not signed correctly" error, this is because your device is not on a user build. If your device is on a "userdebug" build with "test-keys" in the build description, the Google Play Music update will not be able to be installed from Google Play at this time.

Nothing is working. going back to litening rom.

Haha, your note can't sleep because u tak bagi dia minum susu before bed kot.

Now everyone is talking about ICS only. GB dah outdated. kecian.
Yesterday night been flashing here and there.

Mine is Umobile as well , no issue with the data.

search for screen off application.
black in color.

Have you reboot the phone and also check the data is on in the setting.
Also check the APN.
if not, call U Mobile.

Reboot it, still doesn't work, borrow sim card from your friend and test.
If have data then U mobile is sakit.

Hahahah,
Better go and check it out.

So good, the smell of FRIDAY!!!!!

Wow, good morning.
Now you become snr member already wooo.
nice nice

As for me,Instead of i block those apps from starting up i uninstall it using Titanium.

Wipe it

You wouldn't know whether you like it or not unless you flash it.
Just try it.
If don't like it, go back to your stock or other custom ROM.
