They sound like great tricks to me!! I hate it when my batteries get less than half way, if I take both my batteries out for even half a day knowing I will not be returning home to my charger its torture!!! The vapour drop off and still tastes sweet I know that my batteries desperately need their charger right away!! All the used carts that start to make a burning taste go straight in the syringe now, I don't have a dropper bottle yet so they live in the syringe for a day or 2 ready for topping off. Once I get one tho I will buy either liquid or penstyle carts to squeeeze right out since they are the same price as smaller carts
