As always: It depends on what you are intended to do with your drone. When you are very experienced and if you are able to be aware of the consequences of all you do with your drone best mode would be to put the mode on non origine mavic battery and to change the rth point as well as the landing point because in this way you can extend the air born time of your drone. But this is very risky and you really have to know the behavior of your drone as well as you have to calculate wind influence, height and such things. For beginners and even for most of the others I recommand to leave the mode as it is...
