Earlier quoted context omitted.
High-end 15" laptops already have 100Wh batteries, and 100Wh is the practical maximum. So abandoning LPDDR would lead to a reduction in battery life on the high end, which probably isn't going to fly.
> isn't going to fly. Literally - 100Wh batteries are maximum you can take on planes
Strangely, the rule comes from ICAO.
Some countries too follow the 160wh standard, but most airlines simply don't bother enforcing anything, but the lowest common denominator.
