IPhone 5 not charging or turning on?

Basically when i hold down the power button it says it needs to charge so i plug the charger in and it says its charging. Then it comes up with the apple logo as if its about to turn on. It then turns off and says it needs to charge even though the charger is plugged in. What do i do?

Sounds like you need to have the battery replaced. It happens.

You may consider getting a new iPhone SE. Same size, with all the latest tech.

Try cleaning the charger port out with toothpick or needle real carefully to see if any lint or dust in the port, also try different charger

Have you tried washing the inside? Sometimes it gets dusty and damages the connections

  • Wouldn't turning off iPhone while charging shorten battery life? They say the iPhone has a battery life of 400 full charge cycles before it starts its decline. Ok here is the thing… A lot of talk on how to save battery life on the iPhone by charging habits such as turning the phone off while charging, airplane mode while charging, turn off Wi-Fi bluetooth etc… But if the phone charges faster… Wouldn't that increase the amount of full charge/discharge cycles and there for decreasing the life of the battery?
  • Why isn't my iPhone 4 turning on or charging? Nothing has happened to it. It randomly shut off when I wasn't looking and when I picked it up it wouldn't turn on or charge. I Can't try and reboot it with the home and lock buttons because my lock button is broken. How can I fix this, it won't even connect to the computer
  • Why is my iPhone 5 turning off and not turning back on? This has happened twice now. My iPhone 5 has turned off in the middle of the night with a full charge and off the charger, and when I try to turn it back on it takes a couple tries. Has anybody experienced this?
  • IPhone charging cable not supported but still charging? I have a genuine Apple cable that came with my iPhone 6 (updated to the latest iOS). It fully charges up but when it gets to 100% I get a message that says "this accessory may not be supported". I don't see any damage to the cable and I have only had it a couple of months. Not sure whether to just ignore it or not?
