Retina display iPad mini has highest capacity battery in tablet its size
Apple incorporates best in its class battery technology in the Retina iPad mini.
Retina iPad mini review on Anandtech:
The Retina mini now features a 44% larger battery (23.8Wh). That’s nearly the same battery capacity as the original iPad (25Wh), but in a chassis with only 1/3 of the volume. This is also the highest capacity battery we’ve ever seen in a tablet of this size. The negligible impact on weight and thickness is pretty impressive.
The original iPad tablet was released on April 3, 2010 and the iPad mini battery already matched it. Imagine what’s we will see in another three years.
