Agreed. Before, there was no way to quantify battery life unless you go from full charge down to empty and measure the number of hours spent reading or the number of pages/page turns.

I usually charged my PW3 once the battery bar was around midpoint. Whether that was 40, 50 or 60%, I couldn't really tell.

Really, only way to gauge without bias is to test side by side an older PW model and PW4 both running the same (or closest) firmware versions with same settings, library status and book being read, and note the battery drain for the same work.
