Loopy draining the battery on my iphone 4!
edited November 2011
I notice that when I'm using Loopy my battery gets drained at insane rates!!
This is a problem as I want to plug instruments into the data port thus leaving no room to have a charger going in as well.
Oh dear, that's a tricky one! Loopy is indeed pretty demanding, given the hardware, so I wouldn't be surprised if you only got an hour or two out of a full charge. I know there are third-party devices that also provide power (like the iRig MIDI, for example), which is probably the way to go, if you can find one that does what you need.
No probs, just wondered if it was just me :P
