iFixit has completed a teardown of the iPad mini with Retina display and has found a 24.3 Watt-Hour battery, which is slightly larger than the 23.8 WHr battery Apple claims is in the device. The first-generation iPad mini had a 16.3 WHr battery.
Interestingly enough, iFixit previously found the iPad Air also had a battery that was slightly larger than Apple claimed.
The A7 chip in the iPad mini with Retina display is the same A7 found in the iPhone 5s, rather than the faster A7 found in the iPad Air; this isn’t a big surprise, especially considering recent benchmark test results.
iFixit also found an LG display in its Retina iPad mini.
