That's a game mechanic. After power reaches 0% If you don't move your cursor and it's 5AM you have a chance to make it if Freddy doesn't jumpscare you after some time. Not moving the cursor just buys you more time to not get detected basically

I second with this guy. Used his strats and worked beautifully. Your camera only needs to be on the left corridor for the most part and occasionally the kitchen if you want to check if Chika or Freddy are there.

Freddy is the most power draining one. Like he said, when the night starts keep count of how many times Freddy laughed. After 5 you don't need to count anymore since she's only going to the Closet or Kitchen from then on out every time she laughs. When she's in the kitchen count 5-10 seconds before closing the right door, but I recommend 5 seconds to play it safe, because at 5 am that's all the time you get before she attacks usually. Once the doors are closed keep them closed until you hear her laugh again and Chica is not at the door. Repeat the process whenever you hear her laugh. This drains the most power of the night so be prepared. if you forgot where she is just check the kitchen or closet for confirmation. Freddy's usually hidden in the far right corner of the kitchen with cum flowing out her mouth.

With Chica and Bonnie your ears are your friends. Whenever you're checking the camera on the left corridor and Bonnie is not there and you hear footsteps. It's most likely Chica so close the door when you do. (You can occasionally check the kitchen as well to see if she's there to attack or not and at the same time you can see if Freddy is there or not if you lost track.) When you see Bonnie in the corridor you can close the cam and expect her the moment you hear footsteps again 100% of the time if Chica isn't also in the kitchen. And like this guy said. You don't have to turn the light on before you close the door if you hear footsteps. I've found in my case that if I turn the light on before or right after I've closed the door after hearing their footsteps they stay for longer than I want them to. So just flip your camera up and down a few times before turning on the light after closing the door and they should go away, but they are really stubborn sometimes and have a whole ass picnic at the door, so take it with a grain of salt. 

Foxy being the easiest where when you're just quickly checking the left corridor if she's running or not. Just close the door and she'll knock 3 times, wait half a second and you can open the door again. And just because you hear her dialogue doesn't mean she's going to attack. Sometimes she attacks without any dialogue at the start so don't let it distract you and just check the left corridor every 4-5 seconds.

Golden Freddy is barely worth mentioning since you just flip the camera back up again to avoid her. Or don't flip the camera up for a scene, but you get the same scene if you enter 6969 on night 7.
You unlock scene 2 for the 4 characters after you beat night 5 btw. You can get snoo-snoo'ed by them afterwards or just check the gallery.

Your goal is to just be in the office doing nothing for most the time to spare energy and only check the left corridor, kitchen and sometimes the closet for information. (At the start of the night I like to wait till phone guy is done talking or if that's not the case I wait 10 whole seconds before moving or if I hear Freddy laugh once before taking any action to save me some time and power.) Count Freddy's laugh till 5 at the start of the night and afterwards keep a mental note on if she laughed or not so you can open the door. Use your ears for Chica and Bonnie and when you see Foxy running in the corridor close the door. And if you inevitably almost run out of power at 2% or 1% just let go of anything and don't move a muscle. If it's 5 am then you're most likely in the clear if RNG is on your side. If you get that down the game feels way easier. Just focus, count and listen. The worst thing that can happen is boobs in your face AAAHHHHHH! But you got this.
