How come my iphone 4s battery is always low?

When i charge it at night and it is at 1% it only gets up to 50% the next night. Then when it is plugged it doesn't go up it goes down? Any suggestions?

It sounds to me like you need an iphone 5.
The thing about rechargable batteries is sometimes they need to be run down all the way and then charged totally a few times. To trickle charge or just top them off every day is harmful to them.

You also may just have a lemon. Check to see if you are still under warranty.

Go to settings and turn down the brightness. Turn off sound effects when you type and receive alerts and messages. Turn off push notifications that aren't absolutely necessary. Turn off vibration when the sound is on.

If you are recieving noisy, bright, vibrating alerts all night, it will never be able to charge.

If you have a home phone of high speed internet, just start recharging your iPhone as soon as you get home

  • Why is my iPhone battery draining so low? So I bought an iPhone 4 two weeks ago and for a week the battery was GREAT. But now everytime I use it for something the battery drains super fast. Only when it's on standby is it still good, any tips?
  • Why is my battery always low on my new iPhone 7? Ok so I've had my iPhone 7 for like 4-5 months and by accident about 2-3 times my brother for water in it. I know there was water beucase when I played music and sounded weird. It eventually stopped so I wasn't worried anymore but then I noticed that my battery went down so fast. When I first got it it was perfectly fine. Anyways to prevent my battery from going down?
  • Why does my iPhone 5 battery life so low? I recently replaced my iPhone 4S with the 5. Actually the day iOS 7 was released was the day I got my new phone. Anyway, my 4S used to go all day and night without needing a charge, but my iPhone 5 needs to be charged every 3 or 4 hours. Is there something wrong with it or am I simply doomed to have a continuously dying phone for the next 2 years?
