iPod Software 1.2.6 provides improved battery management which solves a problem that may appear to shorten your iPod?s battery life. Some customers have reported that over time their iPod?s battery life has declined. This update enables the iPod to more accurately monitor its battery charge, thus using the entire battery capacity and regaining long battery life. The result is longer playback time and extended standby time. After updating the iPod, customers can expect at least 10 days of standby battery life on a full charge. Prior to this update, the iPod would sometimes mistake a temporary low voltage condition as an indication that the battery was discharged. This resulted in the iPod shutting down prematurely, even though the battery was still capable of powering the iPod. Update your iPod software to version 1.2.6. This update is recommended for all iPod users. Mac OS X Windows Apple homepage
