Apple will launch a new high-end iPad model in early 2012 featuring a battery that includes more than twice the capacity of the current iPad 2 battery. Citing anonymous sources from within Apple’s supply chain, DigiTimesrecently reported that Apple’s upcoming next-generation flagship iPad will feature a new 14,000 mAh battery, as will a new mid-range iPad model. The new power pack will feature more than twice the capacity of the 6,500 mAh battery currently used in Apple’s iPad 2. DigiTimes also reported late Wednesday that Apple’s 2012 iPad lineup will include three models: a low-end iPad 2, likely available at a discount compared to current pricing, a mid-range next-generation iPad and a high-end model. The new mid-range and high-end models will also reportedly feature an upgraded 2,048 x 1,536-pixel displays with dual-LED backlighting.
