Saying “N/A” for battery life isn’t biased, it simply highlights that books don’t need a battery at all, unlike e-readers. As for durability and theft, books can be damaged by water, fire, or time, while a well-protected e-reader keeps hundreds of books safe... Regarding environmental impact, pointing out e-reader e-waste while ignoring the pollution caused by producing paper books clearly shows bias, making books requires cutting down trees, which are effectively killed in the process, plus transportation and processing, while one e-reader can replace hundreds of physical books over its lifetime.
