I thinkimux is rather hit and miss when it comes to battery life on Linux. I've never really quite understood why, as I though ACPI is meant to handle this. But I'm not terribly au fait with this interface, so there might be good reasons, I know Torcalds criticised it early on as a "design disaster" and there were and I think still are concerns about the way that bytecode has unfettered access to the system.
