Sorry that I didn't jump back on to respond sooner.

Re: consumer electronics, the obvious big example is cell phones, and notably major manufacturers have started adding features to extend battery lifespan by capping charge levels. Samsung has had this for a few years, originally capped at 85% but changed in a recent update down to 80%. I believe this occurred around the same time they extended their software support to 5 years. Apple added the same thing in iOS 17 with the iPhone 15 models, but despite obviously having the hardware capability ("optimized charging") they didn't enable the feature on earlier models.
