The battery life of your Lost Vape device depends on various factors, such as battery capacity, usage patterns, wattage settings, and coil resistance. Generally, a fully charged battery should last a full day of regular vaping. If you are experiencing shorter battery life, consider lowering the wattage, charging the battery fully, or replacing it if necessary. It is always a good idea to carry a spare, charged battery or have a backup device available for uninterrupted vaping.
