Any power banks you have, too. It's an extra full charge or two, which can end up mattering a lot. Lots of phones have battery saving modes, I know my Motorola can stretch the battery for probably 3 days or so, on the battery saver mode. Turn the display brightness way down. Every little bit helps. If course a lot of things are more important than phones, but communication should not be neglected.
