For me it was three months from the very minute I uploaded 10.8 (and 10.8.1.and 10.8.2). The things I tried included deleting printer drivers, install from the app store, removing vodafone drivers, pram and that other thing resets, and much more, everything I could find I tried. I live up in the mountains in Southern Europe away from Broadband so it wasn't until I found myself back in the UK in December that I tried the one option left, a clean install from a USB stick drive. Everything back to normal immediately. The day I installed 10.8 I didn't install anything else as it was during my rare visit to the library. Straight away the battery was rubbish and straight away after an install from the USB stick drive three months later I got a decent computer back.
