After a little googling I'm still none the wiser as to whether a MicroSD card in an SD adapter would be easier on the battery than a full sized SDHC card. I have an 8GB Sandisk uSDHC and an 8GB Sandisk SDHC, so all other things being equal I wonder if the smaller card uses less juice.
Any input would be appreciated.
I have a 4GB SD in my 650, and I have loaded all the books on it.
I dont load any books in the main memory.
I use my reader 3 - 5 hours a day, it was last charged on 26/10/2010, and currently the battery is showing 75% full.
However I have found that if I leave it in standby the battery drains a lot quicker, that if I power it of completely between reading sessions.
So I always power it off completely when not using it.
