Compared to a modern iPhone you can throw in a pool and dig out safely a few minutes later.
Batteries post 2007 have gotten REALLY good, the capacity/weight ratio has gone up so much that swapping batteries mid-day isn't a thing people do. Drones weren't a big thing in those times because you couldn't get enough power to lift one up. Now a 249 gram DJI drone can fly ~45 minutes on a single battery that's about the size of 2-3 matchboxes.
I still remember the laptop I had around that time that had two batteries so that I could swap one and still keep it running with the other.
On the other hand my current M2 MacBook lasts for two full workdays without charging easily, even more if I just sit in meetings and don't do anything CPU/GPU intensive.
