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.

exist trick for high ram ?

Hi friends,
trick for increment ram free exsist? sorry my bad english
Thanks

Get yourself a task manager and kill all unnecessary processes, but I don't really know what would you use that free RAM for

ok friend,
for you the best task manager?
double thanks

Use task killer its free in the market, as for me im using System panel.

advanced task manager is the best ,but check this article out
http://phandroid.com/2011/06/16/android-psa-stop-using-task-killer-apps-now/

Android system (2.2 and 2.3--> 2.1 is not too efficent in this) frees the memory itself, and caches things like Windows 7 (but in a far effective way). If you start a software that needs more RAM, then Android frees it for the app (or it tries to free it up: sometimes you have to run more than once a memory hog app to get it started), else it's precaches system things to fasten up the phone. So. If you have a lot of memory free, it's not always good.
Note that the problem starts if the CPU "can't rest". Then will come the less battery time, slowness, choppiness, etc. So: If there is an Application that has been loaded into memory, and runs in background and eating CPU cycles, then it's not good. In this case you have to close it manually. But not for the more RAM. You have to close it because Android itself MAYBE won't close it, because it recognizes as a running task (so it isn't an idle task) that is in use, and it keeps eating the CPU-->battery.
Hope this helps for the memory-geeks

Memory optimisation tweaks? How to get more free RAM?

Any useful tweaks or settings which I could use? There is many appn on the market and they allow to tweak internal memory management but I have no idea what settings to use.
No matter which I try, my phone always seem to stick to ~100MB RAM Free. Why so much? I'd prefer ~50MB RAM Free and more apps running without closing.

you mean you want 100mb ram free but only have 50mb? you can check out a ram cleaner script. the link is in my signature called mods for virtuous unity. just download the zip file, back up your phone and superwipe, then flash your rom then ram cleaning script then reboot and your done

Actually it was the other way around, I always had 100 MB free and my apps have been closed often. I played with one of the tools to tweak internal memory manager and now my free RAM goes down to 60 and apps stay in memory, this is what I wanted. FireFox Nightly takes a lot on its own...
Will play with settings some more before posting them here.
Only app and root needed, no scripts or Rom flashing.
I'm runing CoreDroid port, I love its theme.

My opinion is if what you perceive as a lack of available memory is not degrading the performance of your phone, including the apps which run on the phone, then it's a non-issue as the latest versions of Android have a much better handle on memory management than the older versions.

I agree but in my case system had 100MB RAM free but when I launched another app it would close other app and system would still have 100 MB RAM Free. So imagine me opening media player and listening to mp3 and then I launch Firefox and music stops, yet there is still 100 MB RAM Free.
I have changed settings and it's better now, Free RAM drops down to 60MB so I can have more apps running.
Previously, Firefox would close whenever I switched out of it, annoying.

[Q] need a lil explaination about the storage space on HD2.

Hello all,
I am using the Energy Rom for Android Nand cLK installed. I really have this question in my mind since a very long time never discussed about it though..
The phone by default has 768 Mb of space but then whenever I happen to see in the task manager it shows me 404 Mb where is the rest of the space gone...
I mean i wish to know that is it a current limitation or that's all we can use for android coz when i was using WiMo 6.5 i used to see the entire space show up in task manager..
Kindly give me some input..
I am also attaching the screenshot of my phone.. space..

The rest of the space is used by things like System Partitions, and since you areon a Sense ROM im pretty sure the System partition is around 300 . plus the recovery partition and cache partition, those two might make up around 60 mb, so 300MB + 60MB + 404MB .equals 764 plus im sure there are some bad blocks taking up some space. But yeah you have partitions with android nand that use up the space hope that helps maybe somebody else could broaden the explanation.

You're confusing ROM and RAM. The task manager shows how much free RAM you have, whilst your storage space is 768 mb or whatever it is because it's the internal memory. Those are readings of two completely different things.

Well even in that case HD2 has this spec : 576 MB RAM, 1 GB ROM
Is there a way to know if i have bad sectors and option to rectify them.. coz i believe it's not so..

Thanks in advance...

The ROM is taken up by Android, and the lack of RAM is normal and has always been there.

[Q] I wanna free my Ram a bit

how can I ?

No point
Android will free ram if needed and ram cleaners and anti-viruses often mess this up

]May i ask why you need the RAM? Its android operating system after all if program requires more RAM the system will free enough. You have 1gb free which is more than enough. If you want to free more install some ram killer/cleaner like Clean Master,or uninstall some apps that you dont use. cheers :highfive:

thanks for answers
but it's about the battery, I wanna keep the phone on as much time as I can without needing to charge it
and I thought that all these running apps are consuming the battery and reducing its lifetime

Actually, having apps in the RAM saves battery. It's more battery-consuming to have to read the apps into RAM every time you want to use them. Better have them preloaded in the RAM and always ready-to-use.
They aren't 'running' in the background, but more like 'hibernating'.
If you really want to make sure no apps are consuming data and such in the background, then use Stamina Mode. Also checking which apps are allowed to automatically sync data is one way to go.
