| [* black] Lifting off the LCD exposes iPad 2's battery. This is a 3.8V, 25 watt-hour unit. That's just a hair more than the original iPad's 24.8 watt-hours, so any improved battery performance can be attributed to software and other hardware improvements. | |
| - | [* black] Also listed on the battery is a capacity of 6930 mAh. Since mAh = watt-hours / volts * 1000, converting using the above numbers yields 25 / 3.8 * 1000 = 6,579. It looks like there might be some rounding going on here, or the battery voltage might actually more like 3.7 volts. |
