Anything backlit (color) will have shorter battery life. Making light takes power.

The black adn white (eInk) screens use no power except when you change the display (turn pages).

WiFi takes power. It is a radio transmitter and receiver.

Sony PRS-350 or 650. eInk screen and no wifi (week+ battery life). Touch screen. Robust.
