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.
