We did use them a lot less then. I bet if the screen on a standard smartphone was never used, as well as any third-party apps, the battery would last nearly as long, if not longer, than an older phone.
@DVDBZN@katbyter I used mine a lot. Not just to talk on the phone, but to play snake and hangman, not to mention texting (miss you, good ol’ T9!). But the resolution was crap, there was no color on the screen (and I still use my current phone more often all else being true); if it had the battery my iPhone does today, it would probably last months.
Well, there’s 6.24 x10^18 electrons in a Coulomb (or Ampere-second). Given a 3Ah battery (about typical for a new smart phone), I have 6.24 x 10^18 electrons/A-s x 3600 seconds/hour x 3 Ah = 6.7392 x 10^22 electrons. So I have at least 67,392,000,000,000,000,000,000 of those. That seems like a lot.
