As one of the world's leading manufacturer of smartphone devices, Samsung previously drew flak from the public after their Samsung Galaxy Note 7 caused explosions and fires because of battery problems. The South Korean tech giant recently released their findings regarding the Note 7's battery issues.

Samsung has recently come up with an 8-step battery safety check which is now being applied to all their new releases. According to PC World, there are two types of error in Note 7's battery. The first error is reportedly due to a deficient heat seal that protects the pouch from having a short circuit. The second error on the other hand, is caused by a welding design flaw that results to overheating.

Many consumers have lost their trust in Samsung, but the company did everything to regain their trust. As Greenbot reported, Samsung has since put a premium on its safety processes. This includes putting their very best efforts through extreme quality testing  inside and out of all devices.

These steps start with a durability test, then proceeds to a visual vnspection that evaluates all batteries under the objective criteria and standard guidelines. An x-ray test is done next to examine the inner components of the battery to see if there are any abnormalities.

A charge and discharge test is then done before doing a total volatile organic compound (TVOC) test to make sure that there is no leakage of any volatile organic compound in the phone. A disassembling test is done next to ensure its quality, including the battery's isolation tape conditions and tab welding.

The seventh step is called the accelerated usage test which examines accelerated usage situations. Lastly, the delta open circuit voltage (Δ OCV) test is done to check for any adjustments in terms of voltage throughout the manufacturing process.
