True...is this from the samsung site selling batteries and covers?
Further clarification: the equation we use is P=I*V where p is power and stated on the battery as 7.77 Watt hours. For one hour that's 7.77 watts. V is voltage and is also stated to be 3.7 volts. Plugging in and solving for I, the current, gives 2.1 amps. Since this, too, is for one hour, this can be interpreted as 2.1 amp hours. Convert to milliamps by multiplying by 1000 gives 2100 milliamp hours
Yes, it's the same battery shown on Samsung's site from the other thread. But, Samsung's site says it's a 1750 mAh battery. The web page description and image can all be placeholders for now though. All that said, the calculation appears correct.
