Clawdia, I was very unhappy with the battery life when I first bought my Oasis. I was using the auto back light mode. I went to the extreme of testing the battery life under the conditions Amazon specifies battery life (a very early post in this topic). Amazingly they met the spec. The key was changing the light from Auto to 10. There is a direct correlation between light setting and battery life. WiFi on also had an impact, but less than light.
Since I lowered my light settings I have been ok with battery life, especially since the larger screen was the big lure for me.
So bottom line is they technically meet the spec, but I think the advertised battery life is misleading if you expect to take advantage of all of the features. I wish they had opted for a larger battery & met the spirit of their claims. I never tested my old Paperwhite or Oasis I, but that was because I never had a bad experience leading me to question battery life.
Hopefully Amazon is listening and will make major improvements to the Oasis III !
Cheers, Joe
