I was told the way you charge your phone was how it profits in the future. The best thing to do is to let your phone completely die THEN charge it. I put mine on the charger regardless what the battery is so I can have a charge for the day, or keep it plugged in for the night (which also I was told was bad) just don't do those things and maybe you can train it back to normal.

Maybe because you might have certain things running on your phone that my be draining the battery. Make sure you clear your recents as much as possible.
Ways to SAVE battery
Low brightness!
No games/videos
Try to minimize the amount of pictures, apps, notes, etc.
DON'T USE IT WHILE ITS CHARGING

How old is the phone? Eventually the battery wears out, but it is easily replaced at an Apple Store.

  • 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 6 die so quickly now? I dropped my phone and broke it and had to switch to my old iPhone 5c, which had a horrible battery life. I finally got my iPhone 6 fixed, but now my battery dies so much quicker then before. I'm on battery saving mode, I have bluetooth off and my screen brightness is usually down almost all the way. I do listen to music while i'm in school but that has never been a big problem before and all my apps are closed. What's the problem?
  • Why does my iPhone 5s die so quickly? It does within 5 hours. Barely on it I just click the power button to check the time and it constantly decreases. I've watched it go down like a clock. What tf is happening to my phone.
