Proof?
I'm using a Micro sdhc card, and yes, it's true that it uses more power, but it doesn't cut it by half. It's about 30-60 minute less then you would have with an ordinary Micro SD.
First hand experiences of me testing out MicroSDHC cards in various devices including the Nintendo DS as well as testimonies from my friends and those I encounter online. Not only that, but just reading the MicroSDHC spec verifies this claim. It does offer a higher capacity at the cost of a higher power consumption.
Also as I stated above, I said only certain MicroSDHC cards cut the battery usage in half. The higher the memory capacity of the MicroSDHC card, the more it will drain power. Also there are other factors as well, including read and write speeds, their craftsmanship and so on.
Though your typical 4-8 gig MicroSDHC card made by a decent manufacturer will only see a decrease in battery life to about 30 minutes to an hour, and in more extreme cases, two hours. This is most likely the type of MicroSDHC card you have.
