Interestingly
Apple has so far only ship relatively smaller batteries in their phones.
The battery in the iPhone 7 Plus is 2900 mAh, that of the Note 7 is/was 3500 mAh.
Also, they are only doing very small chances every year, no radical redesign every year.
Maybe they know something that Samsung doesn't?
But I remember reading an interview with one of the Vice Presidents a few years ago where he claimed the "battery chemistry is incredibly complicated".
Also these people are fully aware of the fact that while one mishap would not end it all, it would be a serious event. Fanbois and shareholders (often the same people) would line up with pickets, pitchforks and maybe baseball-bats at 1 Infinite Loop...
