HI there gdgmacguy,
I am not a hardware expert though through what i experienced and saw is what a microsimcard happens to be my old 128sim cropped from around by the gsm operators, not another new card. However, from what i've read trough is, an up to date sim-micrisim whatever you name it, uses the hardware it is installed in to communicate with the satellite andsuch, thus old sims-microsims act loke drinking the battery.
I am not insisting if the subject is relevant or not, i am asking, what apple suggests. If That doesnt matter at all, i wonder what would happen with a 32k sim.
THanks in advance...

Not really. The SIM provides the identification to the cell carrier to link your iPhone with your account, but the SIM itself does not communicate with the cell towers. And as gdmacguy said, the iPhone does not use the SIM for storage. So while I can't say it would be impossible, I very much doubt that the amount of storage on any SIM would affect battery usage.
Apple says nothing about SIM capacity since the iPhone, again, doesn't store anything on the SIM. All Apple says is to use a compatible micro-SIM from your carrier. If you used a cut-down standard SIM, while those often work they are not supported and have been known to cause problems, though battery drain is not one of the problems I've seen associated with such a modified SIM. What Apple officially says about battery usage can be found here:
There are many other tips that have been posted in these forums, some of which have helped, so a search or browing of the forum might be worthwhile.
