CPU shows 77% when nothing is running!!

I am using a standard UK T-mobile 6.5. I have nothing running on the phone, all apps have been closed, but when you click the top right-hand corner, the CPu shows its running at 77%!!
Does this mean that there is something keeping the processor busy or is 6.5 ineffiecient..or both maybe?
Any ideas?
Thanks in advance.

use cleanRAM which is from the best free application for HTC devices

It's not the CPU usage, it's RAM used.

You say nothing is running, but the nature of the beast is that normally there are applications running in the background, Outlook, light & G sensor, the GSM/3G radio, if you use the CleanRam application and looking into the Running processes there is always something running there.
I'm never too worried with CPU or memory usage as long as the device runs fine, I don't care! ...and if it slows down, I just reset (off & on) once in a while (also use cleanRam)

Ram is also ate up by cache that HTC sets. Having lots of apps precached means faster loading of those apps.
If you care about the amount of free memory... then flash a custom rom. The later Official WM6.5 HTC roms are killer.

and remember that unused ram is wasted ram. So what are you going to do with more free ram? It would be there for nothing.

That's all very well, but if the RAM cannot be freed it's a problem when you want to run a program that needs more. I used to be able to run iGO8 navigation software with text-to-speech voices with the stock HTC 6.1 ROM (as long as I did a RAM clean up before starting it - to get RAM usage down to under 55%). Now, with the HTC 6.5 ROM I cannot get the RAM usage down low enough for TTS to work. It's a memory hog.
Anyone got any ideas (with the stock ROM - it's a corporate phone I should not re-flash)?

Thanks for all the responses. I guess is nothig to worry about then.

are task killers a good idea?

I have been using advanced task killer free for a few days and have not noticed any difference in battery life. Shall i keep or uninstall?

same here, but its not bad, and its kill some appz and spece memory - so way not ?

google states that Android Users do not need to use task killers. Programs are left in memory for latter use, the system will even load programd you haven't used yet if the system thinks you might use it. These programs stored in memory use very little power and might actually use more because the program has to reload every time its used. I used task killers for a little. But now i don't.

Android doesn't need task killers really, if memory gets low then Android will close apps to free up memory, I find that if an app is using to much memory though...like a bad app the task killer is useful ..
To find out if an app is leaking memory you can donwload Watchtower for free to take a look whats going on..
I wouldn't uninstall it, just no need to use it so often..Android usually looks after itself..most of the time.

Task killers are actually a very bad idea. Many apps are making use of a background services, killing them as well (what most blind killers do) will result in a totally unpredictable behavior.
As a developer I really hate them. I have one app which totally depends on a background service. I get sometimes really weird error reports... questioning a little further always reveils that taskkillers have blown away the back-end of this app.

Task killers are stupid. Android has a linux base. The linux way is to cache a bunch of data into memory to allow apps to start and run faster.
How much free memory you are showing is actually meaningless because should an app require more memory the kernel will reallocate memory to the active task, automatically stripping it from idle tasks.
If you are trying to save power what its relevant is which apps are using cpu cycles. As fat as I know the only task killer type app which monitors cpu usage instead of memory usage is Watchdog.

Memory and Performance Query

I have one question again. Supposed i have a low phone memory due to so much application installed, will it affect my phone performance, coz i noticed that my phone lags with almost full apps installed in it, I wonder if low phone memory that affects the performance of my phone or bcoz of the running apps simultaneously. One thing after i uninstalled the apps from memory card it still has the folder left in it, is it safe if i remove it manually? Is that the cache? Where is the program files in the memory card where the application is so i can delete the uninstalled apps?
Thanks in advance. Lab2 guys.x0x0

having multiple apps running on your phone will slow it down because each app uses tge phones processor and RAM (random access memory) to function and at different times or circumstances they use different levels of both, leaving multiple apps running leaves tge phone without much memory to get through basic functions such as texting or playing music with ease, there is a simple, easy and free way to solve your first problem, go into your android market and look up "advanced task killer" download the free version and it will show you what is running and how much of your RAM is available and you can stop all the apps from running by just clicking "kill selected apps" and your phone will run alot smoother
as for your second issue, theres nothing to worry about, those folders just contain information the apps that you have previously installed, have downloaded, you can delete them without risk of any damage

so even tho my phone memory is full that doesnt affect the performance of my phone right. i only have 43mb left in my phone memory and its a big laggy to respond. Thanks much. x0x0

or instead using of Advance Task Killer, use Fast reboot to improve battery life. You'll be more enlighten if you visit this site [FIX] Drain Battery Fix for CyanogenMod.

You should worry about how much specific app uses your cpu not ram, less free ram = faster phone.
So try to determinate wich apps are using your cpu and kill tham.
Ignore this post if youre using eclair

Thank you guys for the sweet response. BTW it works i think the prob is my spb3d launcher that makes my phone lags.

Install System application and kill processes from there.

[Q] RAM issue with HD2

Hello guys,
I have a little problem.
I use the "HD2 NDT MIUI Ginger Rom" and its really fast but my only problem is that when I use it a few hours without reboot my RAM falls down to 80MB .
Even when I kill all tasks it's still under 100MB everytime. After I reboot the RAM is like 200Mb or more.
Why is that so? Is it possible to change it?

So what is your problem exactly? The great memory management of this rom? To much free ram? Force closes? Apps not starting?

Get yourself Automatic Task Killer, select all apps and i guarentee youll have plenty of Ram left
I use it on all my roms it works great

Thanks , I'll give it a try and post my feedback here

you don't need task killer.....you do not even have to look at the free memory....just use your phone...you won't have any kind of memory problem... GB memory management is great...!

Not when you have A LOT OF APPS installed. Trust me. Its very needed on Sense roms too. More ram equals faster rom experience

On Android, espacially on miui you dont need a taskkiller. MIUI has a built in taskkiller, just hold the home button. 3rd party automatic task killers are plain bs. Free ram is wasted ram. 80mb of free ram is plenty. More free ram won't speed up your device, it will slow it down. Of course your apps open faster, if they are allready loaded into RAM, not when they have to be loaded from nand or sd first.
Wise words from mrbr0wn:
"you don't need task killer.....you do not even have to look at the free memory....just use your phone...you won't have any kind of memory problem... GB memory management is great...!"

Yes, more isn't always better...

Task Killer are not helpful :/
After reboot my RAM starts with around 200MB but after a while it stucks at 50-40mb even when I kill all tasks.Everything is a little bit laggy then and I NEED to reboot in order to use it again normally. Whats wrong?

i use the "autostarts.apk" (known as a170.apk) to remove all the apps from the autostart list.
When you kill apps, the always open in background again.
Remove the Autostart entry from them and its all perfect now !

I use Sense 3,5 ROM and RAM after my first boot:
Full size 411.50Mbytes
Fluent: 4.67Vbytes
Used: 406.83 MB
What can eats so much memory? What does he do? How to free more RAM?
Or what you can see that it has eaten so much RAM?

RAM terrible usage

Use a program like Android System Info to find what programs are running. If you are rooted just freeze the apps that are safe to freeze and you see running in the background.

am already using Greenfiy and Battery Doctor .. !

Correct me if I am wrong but doesn't Android utilize ram differently then most systems. Isn't free ram wasted ram in this case.
What I have been told is that the Android OS loads apps into memory as a way to speed up processing and increase battery life and automatically empties this ram when more ram is needed. This is done to optimize performance and battery life.
So even if you might not use a certain app, its still left in memory incase u do use it and to avoid random increases in processing power decreasing overall battery life.

You're RAM usage is perfectly fine

what happen with the ram usage ? Is so normally .
Remember , android os system is a multitasking os.
So when you close the program it not totally close , still running in background .

Replace Touchwiz with Apex or Nova launcher, and kill as much bloatware as possible.
Touchwiz alone is 600MB.

Yes, Android manages memory different way and it's stupid way to put it mildly. Unless I manually go and kill useless applications, they take up memory and many of those apps I never used and never ever will. And no matter what anybody tells you it takes time to clear memory for new programs to load and defragment it. Primary reason I had to root my phone to fix this idiocy and freeze or delete all the bloat since I was tired to force stop dozens of apps after each reboot. I won't even go into all other issues like when those programs run in the background wasting battery, use internet, or wake the phone from deep sleep.
And how on Earth loading and running never used apps in background optimizes performance and battery life?
Part of the reason they do that is "just in time" compilation, another stupid idea, which they just tried to fix in KK.
Just like others suggested OP could root and freeze/delete all the garbage he doesn't use and surprise, surprise the phone will run faster and battery will last longer.

You don't need to root to remove most of the bloatware. I didn't, and mine averages around 1.2GB in use with Firefox, Facebook, Whatsapp, LWP, Zooper, Twitter and Gmail open. It boots to 700MB in use.
