I just cancelled my pre-order for the sleep cover (made October 15, still not available at Fnac). That gives me time to see whether a new F/W improves the battery performance, and decide whether I should buy the charging cover. I'm in no hurry since I only use them when traveling and my next holidays will be in January (crossing my fingers there won't be a flare-up of Covid this winter).
I made some tests yesterday evening
- start 69%, light 30%, natural light 3 steps up
- 1st hour => 62% plain reading
- 2nd => 52%, I finished the first book so searching which would be next
- next 34 min. => 44% still much to-ing an fro-ing
- next 8 min. => 35%! idem
- next 47 min. => 21% mostly reading.
So, terrible. But the % tends to drop more and more quickly, and then stall for a long time at 1%, and a full test would need a full discharge, after doing it at least 3 times. Which I did, but I don't have the time to do it anymore since I do like to read on the Sage and don't want to fall back on the Libra 1 on the go. Also I'm always loading new books and syncing reading positions with the Elipsa.
