8-Point Battery Safety Check

Since the Galaxy Note7 recall, we’ve re-assessed every step of the smartphone manufacturing process including our existing safety procedures and developed a further 8-Point Battery Safety Check. It involves putting our batteries through extreme testing, inside and out, followed by a thorough by X-ray and inspection by the human eye. We are making a stronger commitment to safer devices.

  • Illustration signifying the durability test
    Durability Test It starts with enhanced battery testing, including overcharging tests, nail puncture tests and extreme temperature stress tests.
  • Illustration representing visual inspections of each battery
    Visual Inspection We visually inspect each battery under the guideline of standardized and objective criteria.
  • Illustration symbolizing the X-ray test
    X-Ray We use X-ray to see the inside of the battery for any abnormalities.
  • Illustration representing the charge/discharge test
    Charge and Discharge Test The batteries undergo a large-scale charging and discharging test.
  • Illustration signifying the check for Total Volatile Organic Compounds (TVOC)
    TVOC Test(Total Volatile Organic Compound) We test to make sure there isn’t the slightest possibility of leakage of the volatile organic compound.
  • Illustration representing the disassemble test
    Disassembling Test We disassemble the battery to assess its overall quality, including the battery tab welding and insulation tape conditions.
  • Illustration symbolizing the Accelerated Usage Test
    Accelerated Usage Test We do this intensive test by simulating accelerated consumer usage scenarios.
  • Illustration symbolizing the check for Open Voltage Circuits (OVC)
    △OCV Test(Delta Open Circuit Voltage) We check for any change in voltage throughout the manufacturing process from component level to assembled device.
