I have heard that having high affection will ultimately pay off, but having to take long breaks to do both Super Training an Pokemon Amie (both have vital bonuses, but take ages to make a difference) gets in the way of me enjoying the game. So, I would like to know whether affection can be gained through actions like using the pokemon in battle, using them in wireless battles (if regular battles don't work), leveling them up, healing them with potions or berries, or something else I haven't even thought of. (Also, are any of these actually effective methods, where affection gained per time spent is better than using Pokemon Amie (like, if it has a marginal increase and takes hours, I wouldn't consider it a viable alternative, but still mention it just in case).

No. There is not effective way to increase affection without Pokemon Amie. You can do it by using them in battles more and using potions on them but it is more efficient to use Pokemon Amie.
