The batteries used in Samsung Electronics Co.’s troubled Galaxy Note 7 were tested by a lab that belongs to the South Korean electronics giant, a practice that sets it apart from other smartphone manufacturers, according to The Wall Street Journal.
A spokesman for Samsung said its internal testing labs didn’t reveal any problems in the original and replacement Galaxy Note 7 phones. The device was recalled last month and then discontinued last week after original and replacement units caught fire.
For CTIA certification, smartphone batteries are tested on their own and while being operated inside a device, says Kim Tae-young, director at the Korea Testing Laboratory, the only other CTIA-certified battery testing lab in South Korea. The tests mainly focus on whether batteries work properly while a phone is being charged or used for calls, which is when they are most likely to heat up. “We also put batteries in high temperatures that simulate summer conditions to monitor potential overheating or combustion hazards,” he said.
