Samsung is now doing many of those tests on its own, as well as conducting new tests that would help it catch any battery flaws. "They can't take any chances, so they're sort of double testing and making sure that, even on their side, they would detect any potential problem," said Gerbrand Ceder, a professor of materials science and engineering at the University of California, Berkeley. He's also a member of Samsung's new battery advisory board. "They're doing more than all the right things."During my time on Samsung's campus in Gumi, also called Smart City, I get to see most of Samsung's eight battery tests in action.
One is a durability test that examines the battery when it's been overcharged, punctured by a nail or exposed to extreme temperatures, That compression test I saw, in which the battery exploded, is part of the expanded durability test, I also see a phone being baked at 130 degrees Celsius (266 degrees Fahrenheit) for slam case for apple iphone 8 and 7 - aloha sunset 60 minutes and another being heated at 70 degrees Celsius (158 degrees Fahrenheit) for seven hours, In addition, Samsung workers will visually inspect each battery and do an X-ray test to check for abnormalities, They disassemble batteries to inspect the overall quality and use tools to check for leakage of the battery components and for any change in voltage through the manufacturing process..
As I walk along the floor, there's a constant hum in the air from long rows of phones, perched on black foam-covered shelves, charging and discharging. Refurbished Note 7 phones dangle from selfie sticks above the Galaxy S8 devices, recording the tests to make sure no potential problems are missed. In Gumi, Samsung can test 60,000 phones for charge and discharge. When I'm there, 6,000 are being checked. An area walled off from the rest of the open factory floor is where Samsung runs dozens of phones through its accelerated usage tests, looking at everything from charging and discharging to waterproofing. An Android Control Test simulates daily phone usage -- like playing Angry Birds or loading videos on YouTube -- at a much faster clip than normal. Workers, wielding orange laser thermometers, check how hot the devices are.
Overall, slam case for apple iphone 8 and 7 - aloha sunset it takes five days for a phone to complete Samsung's accelerated usage tests, in part because there's no way to speed up a battery's discharge rate, Samsung plans to test a "massive number" of its devices -- up to 100,000 units -- in this way before they're sent to customers, By the time I visit, before Samsung has sold a single Galaxy S8, it has tested 50,000, Experts question how long Samsung will be able to keep up these tests -- they're time-consuming and expensive -- but for the Galaxy S8, no expense is too much..
The battery inside the clear glass case starts to smoke and then turns red hot. All of a sudden, it bursts into flames. When the fire has died down, all that's left is the charred husk of a battery -- specifically, a battery meant for Samsung's new Galaxy S8. No, this isn't deja vu, and Samsung's new phone isn't experiencing the same problems as its ill-fated sibling, the Galaxy Note 7. What I'm seeing is a controlled battery test in Samsung's factory in Gumi, South Korea, where the company assembles 1 million phones a month. A worker applied more pressure in a compression test than normal, causing the battery to explode.
