    I upgraded to snow leopard a few months ago. Its fine but its messing with my battery life. ever since i installed it told me to check battery. now my battery last only a few minutes. ive reset pram and smc but nothing helps. This battery is 8months old. I feel its the software. there is much written about this on forums with people having similar problems. Im thinking of going back to leopard. If i do, what kind of things will i lose? like data and apps?

    If you perform an upgrade your files and applications should remain intact, although I would recommend backing up first. If you choose to clean install you will lose all you files applications etc. Just pop in the Leopard DVD restart and press C on boot up to install.

    I don't think you can "upgrade" to a lower version: only wipe the drive and re-install (so backup all apps and data)

    snow leopard has better power saving features than leopard

    it's possible that the issue is your battery, i recommend having it replaced

    This is correct, to downgrade you have to erase and then install.

    @ the OP: It's unfortunate that your battery died, but it's coincidence and nothing more. SL has better battery diagnostics than Leopard and will tell you when something is wrong with it. The fact that your battery died soon thereafter is happenstance.

    Downgrading to Leopard won't solve anything. Getting a new battery will.

    Wow, some significant misinformation here. Downgrading from a newer OS to an older OS doesn't require erasing the drive, not by a long shot. Leopard and earlier had an install option called "Archive and Install", which will move the OS and other system files to a Previous Systems folder, install a fresh copy of the OS, and keep your User accounts and files, along with Network settings intact. Still best to back up, but no need to erase anything.

    Now, the advice about the battery is probably spot on.

    True! I keep forgetting that OS X has that Archive and Install option... since the system is so stable I rarely reinstall (and when I do, it's an erase and install). Thanks for the correction.
