I have one Samsung phone that has bloated battery too. Once bloated it became dead.

Another Samsung phone that kept power up and down when it could not find the network. This happened when I traveled in India from one city to a remote town when it could not find a network. This was not as scarily than when it happened when I took an internal flight in India. The phone continued to power up and down until it became very hot. I was so frightened that the battery would explode in the plane.
From then on, I would remind myself to turn off the phone before entering the airport.
