Battery life of phone. Option to buy batteries?

@JR-Fi

… but it seems in the future the battery could indeed get better, last longer

… and/or recharge faster.

As not sure if this USB-C power bank with graphene core might significantly extend practical outdoor usage of Librem 5, so asking what is your opinion about it? Anyway, it should be quite usable (instead of carrying around four AA batteries , just comparing two sizes) as portable and ‘rapid recharging’ (1:45hrs) 5000mAh power bank.

Besides, here is an answer to @ballgum previous question:

@Alex

Graphene is one of those things you hear so much about but never actually see it go anywhere.

Really hope it takes off. But as per your question - pretty sure the answer is that Purism will use the best battery that they can find that properly fits the form factor of whatever device is in-question.
