Corrected grammar, changed some words to reflect question better

"Running time" is more suitable phrase than amper hours rating

If the battery voltage is much higher than what is required for the circuit, there SHOULD be a way to get longer battery life. That way is an efficient DC-DC converter such as a buck converter. | |
| Aug 21, 2016 at 7:44 | comment | added | user57037 | Linear regualators have input current and output current that are basically equal. So if you use a resistor or a linear regulator, you will get no battery life extension from the voltage drop. But if you use a DC-DC converter (e.g., a buck converter) then the battery current will be much lower than the regulator output current. D | |
