Since the Galaxy Note7 recall, Samsung has re-assessed every step of the smartphone manufacturing process and developed the 8-Point Battery Safety Check. It involves putting their batteries through extreme testing, inside and out, followed by a careful inspection by X-ray and the human eye. They are making a stronger commitment to safer devices.

8-Point Battery Safety Check:

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