Whenever I charge my iPhone the battery percentage goes down?

Owner of an iPhone 4s

Iphone sucks just like all the technology on the planet. Go live your life without phones you thirsty hoe

There's probably something with your phone's battery. It happened to my phone for how many times.

  • Why does the last percentage of my iphone battery takes so long to charge? I have noticed that the very first percentages (1-20) of the iphone battery charges very quickly, but when it comes to the last percentage (99-100) it takes like 15 minutes to charge!
  • Why battery percentage indicator in iphone is not showing accurate battery? Let its being charged, let it reached 97 percent, it will still showing charging, but if i off/on it, it will show 100 percent, and it shuts off when it reaches 4 percent, please tell what's problem? and as above i said, if i go to "usage" it will show time charged last time:0 mins standby:0mins but at top right its 99percent and is showing charging?
  • My iPhone battery isn't showing the percentage of battery? I did a hard reset on my iPhone and now the battery icon in the top right is there but the percentage that is usually next to it is now gone. I'd like to know how this happened and if I can fix it.
  • My iPhone battery goes down even though it says it's charging? I'm noticing today that my charger isn't the same. It's always worked before but now when I plug it in, I see the little charging symbol on the corner, but the battery percentage goes down slowly. My charger is designed so that when my phone is plugged in, a red line goes on. Now the light is turning on and off, but the charge symbol remains no matter what. I have to stay at a certain position for the light to stay.
