If cared for properly, they should die of old age, but typically, the most common cause of fish death in captivity is a water quality issue due to toxins that are too high.
They can die of one of the many, many betta diseases there are out there, or just of old age. If your fish is suffering badly, just put him/her in a plastic box with water and keep them in the fridge, they will freeze slowly and experience no pain what so ever. They live longer if kept in tanks, usually 7 years (Though eight years is not un-common) but, if kept in bowls- even though they will be just as happy- they will live 1-3 years.
Bettas gulp air. The only reason a Betta would 'drown' is if for whatever reason, it couldn't get to the surface of the water. This could be because it was sick and unable to swim properly, because it was harassed by more aggressive fish, the current in the tank prevented it from being able to 'rest' near the surface, or because it got caught on or under something in the aquarium. I have had bettas in many different sized aquariums and have never had a problem with 'drowning'.

What does it mean when a betta fish lays down at the bottom of the fish bowl on its side?
A betta fish laying on its side at the bottom of the fishbowl could indicate illness or stress. It may be suffering from a swim bladder issue, which affects its buoyancy. Immediate attention from a vet or a specialist in fish care is recommended to diagnose and treat the problem.
Do betta fish like other fish?
Bettas possess what is called a labyrinth organ, which means that they obtain their oxygen by breathing air at the surface (unlike most fish, who get it from the water). Bettas enjoy having somewhat deep tanks to explore and swim in, but they need to have surface access for oxygen.
