Samsung’s devices are renown the world over for their performance and design. However, not too long ago, the company’s Note line up caught media attention for all the wrong reasons. Its signature productivity line had a device that was not only compelling, it was too hot for its body. Independent investigations pointed to a manufacturing defect.
Learning from this experience, Samsung has implemented a slew of tests that it now uses to ensure the quality of the batteries used in all its devices including the Samsung Galaxy Note9. The new tests are designed to detect any short comings. The new 8 step process will be able to detect even the most minute battery defect.
Here’s a quick run through the whole process which will keep you safe and keep your Galaxy Note9 a quality product which you can depend on.
1. Extreme Testing & Visual Inspection
The first thing that any battery is put through when it reaches a Samsung factory is a a Visual test. The battery is inspected for any physical defects including dents, punctures or dis-figuration. These are done with strict adherence to the new Samsung guidelines to ensure it is safe for use.
Of course, Samsung doesn’t just stop there. The South Korean manufacturer goes a little bit further and does an X-Ray analysis to visualise the internals of the battery. During this visualisation, the battery is again observed for any abnormalities.
After the initial visual and X-ray inspection, the battery is then put through the ringer. The battery is checked for abnormalities under different conditions including extreme temperatures, nail punctures and even overcharging.
2. Large Scale Charge & Discharge Test & Accelerated Usage
The batteries are then subject to large scale charge and discharge tests which ensure that the batteries used are up to scratch. This is very important as we tend to charge our devices at least once or twice a day.
Of course, being made for consumers, the company takes into consideration the many usage scenarios of the consumer. In fact, Samsung has made this an essential test for the battery; only batteries that are able to pass this will move on to the next tests.
3. Science & Disassembly
Of course, there are scientific markers which are important to the quality of the battery. In Samsung’s new battery tests, the company tests for volatile compounds to ensure that the battery is sealed tight without the slightest leak of the volatile compound contained within the battery.
The battery is also put through an open circuit voltage test. This tests the change in voltage throughout the manufacturing processes to ensure stable charge and discharge of the stored voltage in the battery and its components throughout.
The battery and components are also checked for integrity through a disassembly of the battery. This allows Samsung to run a thorough quality check of the battery components.
Of course, the steps above are actually a gross simplification of the 8-point battery safety check which the company has implements after the unfortunate incident. But, the important thing to NOTE is that larger battery of the Note9 has been put through these rigid, thorough and comprehensive checks to ensure it’s 100% safe.
