Back in the ‘sweet spot’ of cellphone use, the late ‘90’s, you could get several days of use out of a battery. Some only needed a weekly charge. I also don’t need or want a flip phone to do everything that a smartphone does.

I’m a big proponent of making phones bigger with bigger batteries. I’ve got huge hands and most phones feel dainty and fragile. Give me a house brick with a week long battery and I’d be perfectly happy. Making phones slimmer is just silly.

I get about a weeks battery out of my Punkt, but I don't use it for much besides the occasional text or call. I suspect if I used it more I'd wager I'd get 4 days out of it.
