Galaxy Note 7 launched in August and sold in early September 2016. The device quickly received positive reviews from professionals as well as users thanks to its beautifully designed, powerful configuration, owning a slew of new features, as well as a handy S Pen. However, the battery explosion caused the smartphone to be recalled, damaging not only the money, but also the reputation of the Korean company.


8 Step Test Procedure for Samsung Smartphone Battery

This incident also made some people doubt the possibility of fire on the Galaxy S8. However, according to Cnet, they can be rest assured because Samsung was determined to prevent the situation from happening again, by introducing extremely stringent tests, especially with the battery.

Specifically, the battery of the Galaxy S8 must undergo the test in 8 different steps. First, the company will bring the battery to the test “simulating long-lasting battery life”, using them for voice calls, Internet connection over Wi-Fi or 3G/4G, use the app continuously … and repeat the above steps until the battery runs out. Then the battery was recharged for further use and the test is done for 5 consecutive days.

After the test, the battery was removed from the machine for durability testing. Simulators would perform repression, pressure, drop, high temperature … to see how much they tolerate. In addition, there would be more tests to help ensure that the battery reaches its highest level of safety.

Previously, Samsung often let the battery supplier self-test safety. But after the Note 7 incident, the company sent experts to the test and this greatly improves battery quality. According to journalist of The Verge – Dan Seifert, during testing, over 15,000 batteries were canceled due to failure to meet the criteria.

In addition to safety checks, battery capacity is also a concern. Samsung is no longer running for capacity, instead it’s battery quality. Battery capacity dropped from 3,500 on Note 7 to 3,000, but still optimized for usage time. The battery size also drops, but the durability is increased. According to the company, the Galaxy S8 battery still operates 95% after two years of use, while other batteries have dropped to 60-80%.

Thus, with strict testing process, especially for batteries, Samsung has been more careful to avoid incidents occurring again. With the Galaxy S8, Samsung wants to show the world that the Galaxy Note 7 is just an accident, and that it remains one of the best mobile phone manufacturers in the world. But, to find out if the Korean company is working hard, wait until the product is sold out in late April.
