Welcome to Android Central! It depends the definition of battery life. Do you mean when you start noticing that the battery doesn't last quite as long as it used to, or when the battery absolutely can't hold charge any more? Most batteries will gradually lose their ability to hold charge, so the decline is usually difficult to notice at first. It also depends on discharging and charging patterns. If you habitually drain the battery to zero or near-zero, the battery's lifespan will be significantly shorter (like maybe a year or so. If you make a habit of charging when the battery reaches 30-40%, you can probably keep using it for 2-3 years, maybe more.
