If you're a heavy user, consider rotating between two devices. Keep one in your usual spot—say, the living room—and another by your desk. Not only does this cut down on the urge to overuse a single device, but it also gives each one time to rest. Overheating is a real issue if you're puffing constantly, and a little cool-down period helps.

Plus, having a backup means you're never stuck when one runs out of battery or puffs. That's a practical move, not a luxury.
