Salud!
Thanks, guys, The new firmware certainly has improved things A LOT. If not shut down, my book could lose 2 battery bars overnight, just from being idle. With the new update, after 24 hours in standby and two hundred pages read, it has lost just one. It definitely seems "hungrier" than my previous V3, but it's fully usable now.
(My problem was, I have a Boox labelled "Wolder", whose website just holds firmware 1.2something; I used the one from Onyx's site. Now I'm downloading the one for my WiFi-less unit. Thanks!)
(I read until I drained the "factory charge" before fully charging the battery for the first time; this "second charge" was the one I monitored.)
(I used to have a Hanlin V3 that died on me after just 2,5 years. I wanted to try a different model, and the Boox seemed to me the sturdiest/more comfortable. I'm very happy with it so far, specially now
)
Thanks again!
