iOS 4.0 Why am I running out of free memory so fast?

    Every since I upgraded to OS4, my iPod will never get over 25mb of free memory. When it was on 3.1.3 it would always hover around 40mb, even when backgrounding apps. Now, it only hovers around 7mb, very slow! And it seems that my battery will drain 30% on a regular 8 hour sleep period....

    Is it because I have multitasking and backgrounds enabled on my 8gb MC?

    Yes.Also make sure you turn wi-fi off while your not using it and turn brightness to around 25% to 35%..That will solve your battery issues.

    drop backgrounds => will be fast

    reason: the drop shadows and rendering of the background wallpaper uses OpenGLES v2 which is only hardware accelerated on 3rd Generation+ devices (iPod Touch 3G 16gb+, iPhone 3GS and of course iPhone 4)

    on your iPod it is software rendered=a mess and slow^^

    multitasking tho doesn't influence speed too much but you have to watch out to periodly close not needed apps otherwise you will of course run out of memory

    Awwww man, I really liked the drop shadows on the icons cause I changed them to purple yesterday

    But if it will make my iPod that much faster, why not.

    Would I have to restore it back to 4.0 to clear some of the stuff? or will a simple respring or rebood do it?

    Restoring would be good but you can respring and reboot.

    If that doesn't work just restore.Seems that restoring is always a fix for many problems

    double tap home and then close down the apps^^ that is already enough

    and oh yes they look nice but unfortunately in this point apple is right: the older devices can't handle them =/

    //EDIT: to change backgrounds on/off and multitasking on/off it is enough to edit plist and respring

    Once I jailbreak the 4.0 I'll try backgrounds and multitasking and see how my memory and battery does.If it sucks I'll just remove em hehe :O.

    err - backgrounds does not have impact on memory but on general speed

    it acquires cpu time not much RAM tho^^
    the less available memory I guess is unfortunately common on iOS4 =( I have approx. the same amount (about 30mb after fresh resrping)

    a restore won't change that - the only thing we can do is to do memory management by hand - meaning to close apps when the memory reaches the critical level of 5-7mb (under that red line it will start to lag alot and kill apps)
