A car battery needs to be around 12-16 volts, needs a really high peak current, and capacity isn''t as important. For phones, capacity to size/eight (or energy density) is probably most important. Another note is that if a battery''s "energy rating" is given in Amp-hours, you can multiply by the voltage to get the actual energy stored.
