So here's my question, science geeks. Not stove-related.

I bought a backup power supply for my iPhone (Goal Zero Switch 8) for use on thru hikes. No solar charger needed because that would be overkill the way I use my iPhone on the trail, which is minimally (i.e., just for music at night).

Am I better off waiting for the iPhone to drop to, say, 10%, over the course of several days, before I use the Goal Zero to recharge it? Or just recharging the iPhone off the Goal Zero at the end of each day, however much charge has been expended? How, in otherwise, should I maximize the amount of charging time that I can get from the backup battery?

Thanks for any thoughts. Apologies for the hijack. (This thread maybe could use a little hijack.)


Re-hijack...

If it's just for music is there a reason for not using an ipod nano instead of an iphone?
