Samsung has taken a lot of concrete steps since the Galaxy Note 7 disaster to ensure that something like that never happens again. It has come up with a comprehensive battery testing program to ensure that future smartphones don't suffer the same fate. It appears that the company is convinced that the Galaxy Note 7's battery issues were related to the manufacturing quality and not the actual design.
iFixit tore down the Galaxy S8+ and found that its battery voltage, capacity and design tolerances are “virtually identical” to the Galaxy Note 7. Their unit's battery even came from the same manufacturer as some Galaxy Note 7 batteries, that's not surprising given that Samsung SDI is supplying batteries for the new flagship.
It also found that the design surrounding the Galaxy S8's glued-in battery, including its spacing, installed position and reinforcement “is very, very similar to the Note7.”
The repair experts also point out that the battery is buried deep in Samsung's newest flagship smartphone and is very difficult to remove. This means that the battery is harder to replace.
Just because there are design similarities doesn't mean that it's going to suffer the same fate as the ill-fated flagship. The millions of people who have already pre-ordered the Galaxy S8 will certainly disagree with that assumption.
