Note7 batteries tested internally by Samsung: report Featured

By

Samsung conducted tests on the batteries used in the Galaxy Note7 in its own laboratories, a practice that sets it apart from other smartphone vendors.

A report in the Wall Street Journal said any company that wished to sell phones through major US carriers had to test the batteries at one of 28 labs that had the stamp of approval from the American wireless industry trade group, CTIA.

Testing would ensure compliance with the standards set down by the Institute of Electrical and Electronics Engineers.

Samsung was forced to stop production of the Note7 after both the original phone, and later replacements, combusted. The tardiness of the company's reaction has led to a great deal of criticism; the US Department of Transportation finally issued a ban on the phones being transported by air carriers.

CTIA said Samsung was the only manufacturer using in-house battery testing to obtain certification.

A Samsung spokesman told the Journal that testing did not show any issues with the original and replacement phones.

Apple said it used third-party CTIA-certified laboratories to test the batteries it uses.

Motorola and Nokia have operated CTIA-certified labs but both are being closed, according to the CTIA. The Journal said Motorola indicated it tests batteries at its own labs but uses CTIA-approved labs for certification. Microsoft, which owns Nokia, did not comment. Neither did Huawei.

The chief technology officer at the CTIA, Tom Sawanabori, told the Journal that the association had certified more than 1500 batteries and the Note7 was the first case with a problem.

The CTIA audits test labs to see if personnel are qualified, if they comply with standards, and to ensure that the manufacturers have no undue influence. Such test labs are normally in separate facilities and under separate control, Sawanabori added.
