Coils wear out from heat, and boost mode delivers more heat. The result: coils and pods don't last as long.

Expect your pods or coils to last about 20–30% fewer days when used primarily in boost mode. A pod that normally lasts two weeks might only last 10–12 days on constant boost. A coil that lasts three weeks on normal might burn out in two weeks on boost.

Sweet, dark, and sugary e-liquids (custard, caramel, brown sugar, some tobaccos) caramelize on the coil faster at higher temperatures. If you vape these flavors, the lifespan gap between normal and boost mode is even wider — sometimes 40% or more.
