    Voltage has nothing to do with capacity, as it will vary with charge level. Capacity is expressed in mAh. To find out the battery's current capacity, first charge it fully.

    Then where do you go to find its current capacity?

    Your 3417 mV simply means it's putting out a little over 3 volts at that moment. It has nothing to do with capacity (i.e. how long it can power the phone.)

    The numbers below are the stock battery capacities in milliAmp Hours. In other words, if an iPhone 4 was using 142 milliAmps in a certain configuration, it would last 10 hours.

    iPhone 4 = 1420 mAh

    iPhone 4S = 1432 mAh

    So, yes, the 4S battery is slightly bigger. However, it's also a faster phone which requires more power, so it doesn't necessarily mean the bigger battery will make it last longer than an iPhone 4.

    For comparison the Verizon galaxy nexus has a 1850 mah battery (2100 mah extended oem battery available, not any thicker) and the droid razr maxx has a 3400mah battery. They both use omap 4 soc's which also more power efficient than the a5.
