Buddy meters fill up at different speeds in Hearthstone Battlegrounds based on what is done. The good news is that there is a way to fill it up faster than others, and it does not cost much mana.
Utilizing Hero Powers is the fastest way to fill up your buddy meter. Hero Powers normally cost 2 Mana but boost the buddy meter significantly faster than regular combat. Also, when a hero attacks while charged with a Hero Power, the buddy meter is boosted as if the power had just been cast.
Damage in general does fill up the meter the fastest. Having minions doesn’t seem to do much for the meter.

You can also fill up the Buddy Meter by entering combat, dealing damage, popping Divine Shields, or winning or tying a combat phase. Moreover, heroes receive bonuses based on the number of minions they have at the beginning of combat.
It seems that finishing combat is the second fastest way to fill up a Buddy meter. You should also keep in mind that the higher Tavern Tier buddies will take a little longer to fill up. In other words, building up a Tavern Tier 5 won’t be as easy as building up a Tavern Tier 2 buddy, which should fill up completely every time.
