The customer took his iPhone into the repair shop saying he needed to get the screen fixed and claiming the device wouldn’t charge, when it suddenly exploded in his hands.

The video shows the moment the battery overheated — you can see the man flinch and drop the device as it began spewing black smoke throughout the shop.

According to the store’s account, the explosion blew the screen clean off the phone and led to the shop being evacuated and closed for the rest of the day due to the lingering fumes.

“The customer picked up (the) phone and applied a regular amount of pressure to the screen,” before it began shooting out smoke, according to the shopkeeper’s account.

Security cameras as the store captured the moment from multiple angles as the startled customer dropped the phone and backed away.

“(The) initial force of the explosion caused the screen to come off the phone. Our staff extinguished the phone with a fire extinguisher,” the store said.

“Draw your own conclusions, but imagine if this happened five minutes earlier when the guy was driving to the shop.”

Public awareness of the potential dangers of lithium batteries in smartphones was heightened last year after Samsung had to do an embarrassing worldwide recall of its Galaxy Note 7 due to issues with exploding batteries.
