The Power Indicator is a vital in-game mechanic in Five Nights at Freddy's which displays the amount of power remaining, and the amount of power that is currently being consumed by showing the speed at which power runs out.It is absent in Five Nights at Freddy's 2, Five Nights at Freddy's 3 andFive Nights at Freddy's 4. In Five Nights at Freddy's 2, it is replaced by the Flashlight, and no power source is present to any capacity in Five Nights at Freddy's 3 and Five Nights at Freddy's 4. However, Five Nights at Freddy's 4 has a flashlight, but with unlimited amount of power.In-GameThe Power Indicator is located at the bottom left of the player's screen. It starts off with 100% power; however, the value is rounded down to the nearest integer, making it appear to start at 99% (which is also the reason the amount of power left will read 0% for a while before actually shutting down). The remaining power will decrease at a speed depending on how much power is being used at any given time.For example, having both doors closed and having the Monitor up will cause the power to drain at an alarming rate. Conserve power by using the lights, doors, and cameras sparingly. Below the percentage indicator is a usage graphic that shows two green bars, a yellow bar, and a red bar. If only one or two green bars are illuminated, then the power usage is minimal. If the yellow bar is illuminated, then power usage is medium, and the red bar indicates critical or max power usage.In the Android version, there is a cheat mode which grants unlimited power, fixing the amount of power left to 100%.
