Today's batteries have much more battery density than what was in a 1990's cell phone.Because more battery life = more freedom and less worry.
Back when cell phones first went mainstream, it was commonplace to not have to charge that little green and black screen Nokia more than once every two or three days. Phones have gotten more and more power hungry YEARLY since then, but batteries haven't progressed at the same pace. We've ever-so-slowly grown to accept the fact that our iPhones often don't last us the day, and for most of us, our iPhones are probably our most important computers.
The entire iPhone 13 (and M1 MacBook Air/Pro, for that matter!) lineup is starting to approach battery life that reminds me of the old Nokia days. Where it's no big deal if I don't charge the device every day. Or if I want to get some work done or play a game without having to be concerned that my battery is only 20% charged.
The reason so many people are getting excited about this is that Apple seems to have entirely leapfrogged all the physics problems of battery tech and all the power problems of high refresh rate screens and once again zagged while everyone else zigged. It is absolutely mind boggling to think about the capabilities from here in.
The biggest difference is that we spend so much more time on phones than we did when a phone was used for phone calls and the occasional game of snake. An iPhone in your pocket is now your television, walkman, camcorder, computer, GPS, Gameboy, mailbox, encyclopedia, personal assistant, newspaper......
Even without the Apple innovations you mentioned, I can easily finish the day at 80% if I put it down and forget about it like I did in 1997.
