People are often surprised that InkView runs for weeks on a small battery. The trick isn't a huge cell — it's the display technology.
Bistable by design
An e-ink screen is bistable: once a pixel flips to black or white, it stays there with no power at all. The panel only draws current during the brief moment it redraws the image. Hold a frame for an hour, a day, a week — it costs nothing.
An LCD, by contrast, has to light every pixel continuously. That backlight is what drains a tablet in hours.
Refresh on your terms
Because each refresh is the only thing that costs energy, battery life comes down to how often you update:
- Default — a few refreshes an hour → around six weeks.
- Quiet hours — pause overnight → stretches into months.
Quiet by nature
No backlight also means no glare and no light pollution. InkView reads like paper on a shelf — there when you glance at it, invisible when you don't.
