Why did my iPhone 5s battery die overnight?

My battery was at about 95% before I fell asleep. When I woke up I checked my phone and my battery only had 10% left. Why did this happen?

Turn off blue tooth and push technology. You can also shut down any running apps that you are no longer using

You may have some app's running

If you leave it out it drains the battery… Plus you may have apps running wich may also cause it to die

Maybe you have a resident ghost which drained the battery…

Because it's an iphone.

My iPhone 5s does the same thing! But to save my battery I make sure the flash for notifications is off the Bluetooth is of and all my apps that are running are off, sometimes I put it on airplane mode to and that really helps!

  • Why does my iPhone battery die so quickly? I had my iPhone for about a year and a half, and recently I've noticed that the battery is draining incredibly fast. I've always had it on 3g internet/Wi-Fi and the battery never died this fast so I don't know what the exact problem is. I charged it to 100% yesterday and I only used it for maybe about 10 minutes and left it untouched for the rest of the night. Today when I woke up the phone was dead. I haven't changed the settings or anything fyi.
  • Why does my iPhone battery die so fast? I have boost magic, which is supposed to help my battery last longer, and I kill all my apps when I'm done using them. I go from 100 at 8am and I'm at 60 by 9:30am. And I hardly use it too, just to look up information quickly and I just set my phone aside. I let it go down to 20% battery and let it charge over night. It just started doing this recently. I also keep my brightness to pretty much 0 with the auto brightness on. And it still dies fast. What can I do?
  • Why does my iPhone 5 battery die so fast? Yesterday I left my phone to charge over the night and today about 8:20am I skyped my dad! I was talking to him on Skype for about 1:10 hours and then i didn't use it at all! Now my phone at 12:10pm is 50%. Why is it dieng so fast! Pissed as f*ck
  • Why does my iPhone 4S die when my battery is full? I recently got a used iPhone 4S and the battery is terrible. My battery can be at 100% and ill take a picture and it'll die. I can't use my phone for more than 30 minutes at a time. I've even had to buy a portable charger and it will still die. It's dies randomly all of the time even if my battery is full. What should I do? What's the problem?
