I’m using an iPhone 4s, Sonic Port, and positive Grid with my Bass for practice, and works very good. Also use an iPad 4th Gen on occasion. Got a new iPhone 5c, so thought I would dedicate the 4S for this purpose only. So put in Airplane mod, turned off Locations, and all networking services to help save battery life.
My question, or problem is, I want to start using it live through my bass amp, but the battery life sucks!. I replaced my battery in the iPhone, but still will not make it through a 4 hour night. Wish Line 6 would make a cable that allows an outside power source while connected to the IOS device.
Has anyone found a solution to this problem? - Thanks
