Battery Charge Guide: Stamina Math Builds or Breaks Your Roster

So I’ve been playing Zenless Zone Zero for a few weeks now and honestly had no clue how the energy system actually worked under the hood. I kept burning through battery and wondering why my roster progression felt so slow. Then I came across this battery charge guide that breaks down the stamina math and everything clicked. It explains exactly when Polychrome refills make sense, how to buy Polychrome safely through Lootbar top-up, and the daily caps you should never ignore. Highly recommend if you’re trying to be efficient.
