That's a good idea to turn wifi off on the Oasis 2. I only use wifi when needed. Then turn it off again. Another suggestion would be pressing the power button and wait for the " turn screen off prompt " to shut it down instead of just closing the magnetic cover if you use one. That's what I do to keep it from losing battery percentage over night. Everything adds up on the Oasis 2. Little things could improve your battery life. I hope it works for you too.
