Did In-House Testing Fail to Detect Samsung Note 7 Battery Problems?

Did In-House Battery Testing by Samsung Fail to Detect Note 7 Problems?

Samsung (KRX:005930) tested the batteries for the exploding Galaxy Note 7 in a self-owned lab.

It is the only manufacturer of smartphones allowed to test their phone batteries in-house, according to The Wall Street Journal (WSJ). The rest of phone makers must analyze their phone batteries at one of the 28 labs certified by the Cellular Telephone Industries Association (CTIA), a trade group representing the wireless communication industry.

Phone batteries must go through an experimentation and assessment process in order to comply with standards established by the Institute of Electrical and Electronics Engineers (IEEE).

Samsung officially stopped production of its newest device, the Galaxy Note 7, last week due to reports of the phones exploding, igniting and melting. This came roughly a month after it decided to recall and halt shipments of the product.

Is The Atypical In-House Battery Testing by Samsung to Blame?

The battery is the source of these potentially dangerous malfunctions. A representative for Samsung said that no problems were detected while at the internal testing labs, according to the WSJ.

“We are working with the U.S. Consumer Product Safety Commission (CPSC) to investigate the recently reported cases involving the Galaxy Note7,” Samsung said in an official statement last week. “Because consumers’ safety remains our top priority, Samsung will ask all carrier and retail partners globally to stop sales and exchanges of the Galaxy Note 7 while the investigation is taking place.”

But there have been reports of other Samsung products breaking down and becoming harmful.

Marie Terrio’s Samsung S6 Active mobile phone was “crackling and sizzling” in her front left pocket and burned severe gashes into her thigh and shin, according to an exclusive story for The Daily Caller News Foundation (TheDCNF).

Terrio went to the hospital and was treated for second and third degree burns that resulted from the combusting cellular device.

“My leg looked black and the pain was unbelievable,” Terrio told TheDCNF.

A California man is suing Samsung for intense burns allegedly caused by his Samsung Galaxy S7 Edge.

Batteries are the identified cause in the majority of examples of overheating or exploding mobile devices.

Samsung testing its own batteries seems like it could potentially be a conflict of interest, in which a manufacturer may be more likely to green-light a battery for reasons of profit motive.

John Copeland, a former employee of Motorola who now works at a battery test lab in Atlanta, said that cellphone developers would use their own labs because it would help maintain secrecy over the products and the features.

Manufacturers are “very concerned about their proprietary information leaking out,” Copeland told the WSJ.

Copeland believes that the audits were thorough enough to ensure an absence of conflicts of interest.

[POLL] How Much Mobile Data Did You Use Last Month?

The Results of this Poll Will Help People Answer the Question, How much mobile data do I need?

How attached are you to your phone?

If you’re using your phone for just about everything — maybe your business takes you on the road quite a bit — then you’re likely using a lot of mobile data.

If you’re tethered to your desk or your laptop in the confines of an office, not so much. There’s probably no need to  use your smartphone for anything but calls — and maybe not even that if you can contact colleagues via Skype.

Your Answers are Going to Help People Answer the Question: “How much mobile data do I need?”

So we’re curious. Which group do you belong to? Or are you somewhere in between? Are you using enough data for your carrier to name a plan after you or is your approach to data kind of old school — circa 2004?

Take a minute — check your last bill or your phone’s settings — and answer this week’s Small Business Trends poll question:

18% applicants did not write CAT: IIM

New Delhi: Around 18% of those who registered to appear for the Common Admission Test (CAT) that serves as a gateway to elite Indian Institutes of Management (IIMs) and scores of leading B-Schools in the country chose not to do so, test organizer IIM Ahmedabad said Monday.

The jury is out on the reason for this—the possibilities include an extension that simply saw non-serious candidates apply, an erosion in the brand of IIMs thanks to new ones, and the emergence of more lucrative (and time-bound) opportunities especially in start-ups. The 18% compares with around 14% last year. All told, in 2015 (for admission in 2016), 218,664 registered and 179,602 appeared for the examination.

An IIM professor who asked not to be named said the extension of the registration widow saw non-serious candidates applying.

According to IIM Ahmedabad, the total number of registrations for CAT was 183,032 on 20 September when the original deadline for registration ended. IIM-A extended the deadline for five more days. That took the registration number to a five-year high. “If you see the original registration (183,032) before extension and the number of students who finally appeared (179,602), then you realize that the IIMs have to be careful while chasing numbers,” the professor added.

He also said that the increase in the number of IIMs from six in 2007 to 19 now has not helped the brand much.

Ulhas Vairagkar, an alumnus of IIM-A, said the large number of no-shows may also be because the test was conducted on a single day in 2015. Previous editions had a window that spanned days.

More women

The IIMs’ effort to increase diversity, though, seems to have paid off, with the number of women candidates increasing by around 2 percentage points to around 32%. “More women sitting for CAT or entering IIMs is always good. IIMs themselves are promoting it. I believe co-ed education is always better and, second, it’s easier to place girl students in jobs as companies are now trying to correct the gender ratio,” said Vairagkar, who is also the founder-mentor at the Vanguard Business School, Bengaluru.

This may also mark the first time IIMs are tracking transgenders, a blow for gender equality. In 2015, 41 transgenders appeared for CAT, IIM-A said.

Engineers rule

IIM-A said the total number of students in the 100th percentile was 17, of which only one is a woman. There are 1,814 students in the 99th, of which 136 are women. And there are 9,003 in the 95th of which 1,243 are women.
