Hey guys, just curious what everyone's battery life is like? Casio's site claims 9 month battery light with no exposure to light for my 7900, but the batter gauge has gone from full charge to low in less than 5 days. Yesterday it dropped to low, so I laid it outside on my porch in the sun all day and it jumped back up to high, and after one day it's back down to medium again. Is this normal or is something wrong? I do have power save function turned on, but I have never seen it in "sleep mode" with the screen turned off. I also have the auto EL function turned on, but it rarely even work when I actually want it to, so I don't think that's running the battery down either. Other than that, the only other issue I've had is getting the atomic signal to sync, which is odd because it did it on its own on Christmas day, but now (in the same room) I can't get it to sync up manually, and it hasn't done it successfully on its own since.
