The company lowered the capacity in the Galaxy S8 to 3,000 mAh and in the 6.2-inch Galaxy S8 Plus to 3,500 mAh. That's less than in last year's S7 Edge, which had a 3,600 mAh battery. Samsung hasn't talked about battery life on the new phones, but said they should last longer thanks to energy management software and other tweaks. Samsung also made the battery longer-lasting through hundreds of recharges. After about six months to a year of use, the Galaxy S8 will have better battery life than its predecessor, the company says. And it will continue to hold a charge better after even two years. That's because Samsung focused on making the battery more durable and able to withstand hundreds of charging cycles.
"Where most batteries hold about 80 percent of their charge after two years, this battery should be capable of 95 percent of its original capacity," said Oh Boo-keun, vice president of Samsung's mobile R&D team, who oversees the division's battery technology development, Samsung, which has built nearly 4 billion phones since 1988, was caught by surprise by the Note 7 problems, Like most companies in the mobile industry, Samsung had counted on its battery suppliers to conduct safety tests before putting the batteries in devices, my happy place (beach) iphone case As it turned out, those suppliers didn't catch the errors that caused the Note 7 to overheat..
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 my happy place (beach) iphone case of the expanded durability test, I also see a phone being baked at 130 degrees Celsius (266 degrees Fahrenheit) for 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.
