I estimate about 2 months for moderate use. Moderate use being in
the order of 5 minutes active per day, every day.

But this is just a very very rough estimate. Several factors play
into this, including

- the number of uses per day,
- how responsive the UI is (i.e., how long it takes until you
  get to the password),
- how much light it produces (the more pixels on the higher the
  battery drain),
- individual auto-lock time preferences,
- how much of the time you run on USB power (the two months are
  for battery only),
and so on.

Whether the battery life is acceptable will have to be determined
with devices in real-life use. If it sucks, we can always try
something else.
