The alleged new battery will be 1440 mAh, up from the 1432 mAh battery seen in the 4S.
With such a small boost, the phone will likely see a few more minutes of life, or possibly not if the new devices adds a 4G LTE radio and a 4-inch screen, as expected.
Additionally, however, Apple seems to have upped the voltage to 3.8V from 3.7V, with a higher watts-per-hour rating of 5.45 compared to 5.25 wHr for the 4S.
Of course, take all of this as rumor for the time being, as the battery could be an upgrade for older devices or could have been scrapped in production.
