Now with 100% less boom.

After Samsung figured out what went wrong with the Galaxy Note 7, it set to get in front of any battery problems for future phones. The main result was the highly publicized eight-point battery check, which incorporates new and existing tests for battery flaws.

What hasn't been revealed until now is that Samsung altered the battery design of its next flagship, the Galaxy S8, in the wake of the Note 7.

On the spec sheet, Samsung rates the S8 at 3,000 milliamp-hours (mAh), the same as its direct predecessor, the Galaxy S7. But Samsung employees told me during interviews at the company's headquarters in South Korea that the capacity is actually slightly less because of the battery redesign.

However, the practical battery life of the phone is still longer, Samsung says, because improved internal components and software manage the energy more efficiently. And there's an arguably better benefit: The life cycle of the battery is lengthened, meaning it shouldn't lose as much of a charge the longer you own the phone.

"The battery life is extended longer than that of the S7 thanks to adding energy-management software and incorporating energy-efficient component[s]," according to Samsung Vice President of R&D for Mobile Bookeun Oh, who oversees battery development. "Furthermore, we focused on maintaining the durability of the battery over the long term, over hundreds of charging cycles. While most batteries hold about 80 percent of their charge after two years in usual cases, this battery should be capable of 95 percent of its original capacity.”

So what exactly did Samsung change in the S8's battery tech? The company didn't give further details. Consumers, of course, will never know the difference either way—and that's really the point.
