Am I missing something?
There's a granted ability that ends the battle without forfeiting. If you time out your kills get counted for the "Kill 600 B1 droids" feat, but you still didn't "win" the battle, since a time out is always a loss.
The granted ability is an icon right above your character's normal abilities. It looks a bit like a spiral, as @Lumiya has said above.
Kill 60 or more, and then with time still on the clock, tap on that granted ability button. (If you just get 20 kills, you'll still advance, but you'll only get one star -- the number of stars is 1 for 20 kills, 2 for 40, 3 for 60 or more.)
Good luck.
