To get the most out of your phone's battery, don't let it drain to zero. The best idea is to juice it up at the 30 percent to 40 percent mark, according to batteryuniversity.com.
A battery that runs down to zero will last for 300 to 500 charge cycles, but regular half-charges allows the battery to run for 1,200 to 1,500 cycles.
You can also extend battery life by making a point to unplug the charge before the phone reaches 100 percent. If you are turning the phone off for extended periods, run the batter down to a half charge before you turn it off.
Finally, keep the phone away from extremes of heat and cold.
