Kritsada Supol, 24, had laid down on his mattress with his Samsung plugged into an extension power point with a ‘cheap’ charging cable.
He reportedly appeared to have been listening to music or talking to someone, with the mic section of the earphones resting over his lips.
The property owner visited the room the next morning on Sunday and found Kritsada’s lifeless body on the mattress with signs of burning around his ears.
Police from the Phan Thong Provincial Police Station in Chonburi, Thailand, arrived and carried the dead body from the property before sending it for a post-mortem examination.
Police Captain Jaleuk Polthong said police believe that Kritsada was fatally electrocuted while using the earphones and charging his smartphone at the same time.
The captain said: ‘’We believe a short circuit caused his death while he was on the phone with someone or he was listening to music.’”
