What comes to your mind when someone mentions the Galaxy Note 7? It's probably the device's flawed battery that was a fire hazard. The battery was the entire reason why Samsung had to discontinue the Galaxy Note 7 weeks after it was released.
Samsung reevaluated its battery supply chain after the incident. It ceased all business with a Chinese supplier that supplied a chunk of those batteries. That same supplier has gradually been brought back into the chain. Now it has emerged that the Galaxy S22 series is also going to use batteries from the same supplier.
ATL and Samsung SDI both supplying batteries for the Galaxy S22 series
China’s Amperex Technology Limited (ATL) was one of the suppliers for the Galaxy Note 7's batteries alongside Samsung SDI. ATL was cut off from Samsung's battery supply chain following the incident.
Samsung has since put in place rigorous safety measures to ensure there's never a repeat of that embarrassing episode. ATL might have been able to meet Samsung's strict standards as the Korean giant has reopened its business relationship with the company.
Batteries from ATL are currently being used in Galaxy A/M series smartphones, Galaxy Watch and Galaxy Buds wearables. ATL has even supplied batteries for Samsung's flagship models. The Galaxy S21 series utilizes batteries from both ATL and Samsung SDI.
Korean media is reporting that ATL and Samsung SDI will also supply batteries for the upcoming Galaxy S22 lineup. The fact that Samsung is using ATL once again for its flagship models shows that its technology and safety has continued to improve.
The Samsung SDI-made Galaxy S22 battery has already leaked online. It has a rather disappointing 3,700mAh capacity, a 300mAh decline compared to the Galaxy S21's 4,000mAh battery.
