I changed my setting from smart choosing of satellites to having them all multi band selected. I saw online also to turn data recording from "smart" to "every second". Before I do that though will that greatly affect my battery for a marathon this weekend? and I also saw that makes the overall file size bigger, is that something that I should worry about? I have the 265s. Or should I just leave it on smart and just forget it? I'd hate to get half way through the marathon and run out of space and lose my run. I don't have any apps installed on the device so I should have fill memory although I don't see how to check that either
