14 DAY TRIAL // If you’re wondering how the iPad Air can be so thin and light yet still hold up for 10 hours straight on a single charge... well, the headline has already answered that question for you.
So for the rest of this post I’ll give you the specifics. As it turns out, Apple managed to come up with a display (well, not Apple but the Asians) that requires far less light emitting diodes (LEDs) to light up the dense Retina screen used in the tablet.
The backlighting modules are, more often than not, the primary source of power drainage in almost any device that uses a display.
The findings were made by research firm IHS. The iPad Air uses 36 LEDs to illuminate the screen, whereas its predecessors (iPads 3 and 4) used 84. In a way, Apple was forced to make its iPads bigger so it could make room for a big battery and retain the advertised 10-hour battery life.
