How strange that no-one seems to have picked up on the fact that SD cards appear to suck battery power out of certain devices like a Hoover in a room full of talcum powder. I was first alerted to this by the fact that this ‘ere Siemens SX1 handset wot I am currently using has a standby time of some 12 hours or less with a 256MB MMC card inserted, and around 5 times that (or more) with nothing inside.

Intrigued, I googled, and lo!, it appears that other smartphones also suffer the same effect, albeit via SD cards rather than MMC.

This is not good news, especially as we move up to larger card capacities (presumably with bigger power drains) and smaller, more feature rich and power hungry devices.

Or could this simply be a bad/faulty hardware design issue?
