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.)
Actually, I could use a little Jack Daniels, but whatever. smile

Bee has it right in her answer: minimize power drain, recharge often. With lithium based batteries, from what I've read, you want to charge them as frequently as possible. In fact, were it reasonable to do so, you'd probably want to do it more often than just in the evening.
