Why is it that AA batteries can have a small form factor and hold 2700mAh while my phone battery is huge and stores less?
mAh or mili Amp Hour isn't a measurement of energy. Amps measure the amount of electrons flow per second, but does not take into account the "Pressure" behind those electrons Energy(Watt Hours) is Amp Hours X Volts. Volts is the "Pressure" behind those electrons.
The Short Answer
mAh or mili Amp Hour isn't a measurement of energy. Amps measure the amount of electrons flow per second, but does not take into account the "Pressure" behind those electrons Energy(Watt Hours) is Amp Hours X Volts. Volts is the "Pressure" behind those electrons. AA batteries are either 1.5V(alkaline) or 1.2V(Rechargeable), while the cellphone batteries are typically 3.7V Your 2700mAh X 1.5V = 4 Watt Hours. This is equivalent to only a 1095 mAh, 3.7V cellphone battery. Most phone batteries are > 2000 mAh
