Probably it's stuck at a value for vfs_cache_pressure of 10. I had that problem today. Just to be sure, type this on x-terminal (xterm):
It should show a value of "100". Otherwise, battery patch not applied correctly.
If all was right, type in xterm (be sure to be in a directory with write permissions as MyDocs):

After hitting enter on the second command you'll have to close keyboard and lock phone. It should show a value of "10". Otherwise, battery patch not applied correctly.
If it is all right, then you could uninstall speedpatch and check if it works better than with speedpatch. It seems that not all people here are getting great results. Check that.

If it's not right try to follow instructions given, use common sense, and try to set the things in battery patch to default, and then try to reapply it. I had to do it twice today. First time I was kind of tired or so to get it working...

hey u mean that after

sleep 10 && cat /proc/sys/vm/vfs_cache_pressure >> patch-test.txt
i should press enter? and then close keyboard and lock the phone. and then unlock it and it should show 10? nd then i type the 3rd command
leafpad patch-test.txt
yeah? correct me if im wrong

Are you daft? Look what that nice guy just wrote you (emphasizing mine):

Can you ever just follow instructions without keeping to ask the same question in different incarnations over and over?

after this command
sleep 10 && cat /proc/sys/vm/vfs_cache_pressure >> patch-test.txt
i slide the keyboard down n lock the phone. after i unlock it it doesnt show me any value. it just takes me to the next line.

@Zurrain101

In the second command, the output is being redirected to a file named patch-test.txt. That's why you are not getting anything on the screen.

sleep 10 && cat /proc/sys/vm/vfs_cache_pressure >> patch-test.txt


The third command will show you the output.

leafpad patch-test.txt

If you get any error related to leafpad, try to check if it is installed on your n900, if not, install through fapman.

Hope it helps.

i am getting this in leafpad.

guess ill have to remove the battery patch n install again

@zurrain101
I've had the same problem but it wasn't batterypatch. It was another little proggy that wasn't installed correct probably. After uninstalling this prog and reboot everything works fine again. And by the way your listing shows that batterypatch works fine.

@karam
Thanks for your hard work. I've had modified my phone before i used your patches and had a standbytime of nearly four days. Now the phone has a standbytime of more than five days and it's pretty fast.

@all
I'm not using karams ideal profile, because I build my own based on the starving-profile and with some more overclocking. Less power and more speed But this profile propably not working on the most devices 'cause it brings my n900 to the limit.
For those of you that want to try I've attached my profile.

Sorry, maybe my post wasn't clear. Yes, it was just to redirect the value to a file. Then you could open the file and see the value. Thinking about it now, you needn't the file, so you could just
With that it would output to xtermina without needing to open any file.

Anyway, I see that theree's a 10 value, so the patch should be functioning (you didn't set it manually and thus that value, did you?). But there's a lot of 100 values. Did you wait the 10 seconds after executing command, without unlocking the phone? If not I would recommend you to remove the battery patch and reapply it carefully again, paying attention to all commands and trying to understand them. You would learn something, for sure.

Oh, you can remove the file:
If you rerun the commands I posted the file will be created again. If you wanna test again use the first command in this post.

EDIT: Sorry for not being clear. "sleep" command waits the seconds you set as parameter without doing nothing but wait. I put that to give you time to lock the phone. Yes, maybe I would have had to explain that before. I give you this advice: try to learn what commands do, that way you'll be able to fix things, or at least know what you're doing. It's slow but it's satisfying and useful

hey i did not wait 10 seconds. i will now n will tellu.
i am gonna write this

sleep 10 && cat /proc/sys/vm/vfs_cache_pressure
then gonna slide down and lock my phone for 10 seconds and the gonna unlock it and then gonna post here what values it showed in xterm
thanks

hey i checked and its showing 10 in xterminal so batt patch correctly applied. now i should remove speedpatch n try without it
thanks
