Yeah, even though batteries have gotten smaller, and I’d prefer a larger one, mine still trivially lasts a day. I’ve got an inductive charger at my desk too, so it’s rarely drops below like 80% even. They easily last long enough that carrying extras to hot swap is not required and just a hassle. I guess if you’re going camping or something, it might be nice, but that’s about the only situation I could see being useful.
