IPHONE 4S BATTERY DRAIN

Hey so i just bought a brand new iphone 4s and it works good but when i go to sleep over night, i lose about 10-20 percent on my battery life, is the battery a dud? Should i return it for a new one?

i've tried all those little tricks to help save battery life on youtube but none really work

Put it on do not disturb when you go to sleep

That sounds about normal, the iphones are sorta still running unless you completely turn them off or plug them in overnight, sorry for the inconvenience!

No its not normal, mine only loses about 2-3% (sometimes only 1%) when i sleep. That is with mobile data off and Wi-Fi disconnected. But mine did lose battery quicker when it was brand new so i suggest you use it for a few weeks and see if the battery gets any better.

Calm down, it is normal!

Actually, someone once told me that you should completely drain your battery and then charge it. When you do that you save your battery life. So I followed the advice. My battery stays charged for about 2 or three days now!

  • Why does my iPhone battery drain so quick? I took my phone off the charger at about 9:30am, it's now 10:01am and it was on 100%, I hardly used it, I only went on Facebook to check the newsfeed and reply to an inbox and now it's on 87%? I was watching it go down and it goes down 1% roughly every 2 minutes. It's been happening for about a week now and I'm lucky if my phone lasts me half a day. What can I do (WITHOUT BUYING A NEW PHONE)
  • Why does my iPhone 5 drain battery even when I don't use it? My battery keep running out even when I don't use it. I tried to turn off location services and brightness and stuff but doesn't really help. What should I do?
  • Why does my iPhone 5 battery drain fast? Ok, so, I charge my iPhone up to 100% battery, It's on the night, so I don't use it, I just unplug the iPhone after it's charged, and put it on my table, the next day in the morning, it drains to 98% or even less, I already turned off all the things that drain the battery, IOS 7.3 by the way. And umm, I turned off the parallex, app refresh, lower brightness, pretty much everything off/disabled, even Siri, Why does this happen?
  • Battery on my iPhone 4S doesn't fully drain? My battery life is weird instead of draining all the way down to 1% it dies at around 12%? What can I do to change this? Or improve battery life overall?
