This is a most excellent place for technology news and articles.
I mean, US Cellular had a free battery swap program for a while. If you were a subscriber and your phone battery was low, you could go into any store and they'd swap you out for a fully charged battery for free. I presume they just ate the cost of damaged or degraded batteries as part of it. I only used it a couple times, but it was kinda nice.
