Hi there, I've had my iBook G4 800 for a little over two years and all has been sound and dandy. Over the last week or so I've noticed a rapid decline in battery life; it now averages around 30 to 40 minutes at best, and this is with "Better Battery Life" selected as default. Once the battery charge meter reader hits 26% it very quickly warns me that I'm running on reserve and it's gone!! Does this sound like knackered cells and typical of a two year old battery? Or... are there any emerging issues with 10.4.4 and false battery readings?? Ta very much -- any advice or thoughts would be very much appreciated!!
