This is the most noticeable trade-off. More watts = more current drawn from the battery = shorter runtime.

On a typical pod system with a 1000mAh battery, switching to boost mode all day reduces battery life by roughly 20–30%. If your device normally makes it from morning to evening on a single charge, expect to need a top-up by mid-afternoon on boost.

The effect scales with how much you vape. Heavy users (5ml+ per day) will see the biggest absolute drop — sometimes 3–4 hours less runtime. Light users may barely notice the difference if they only occasionally boost.
