IPhone 5s well not charge or come on?

I finally got my iPhone 5s back after I had put it in the pined shop back in July ( 4 months ago ) when I took it there it was dead! I just got it back and I put it on the charger and it's not charging the screen stays black not even the little dead battery thing comes on I tried resetting ( holding the home screen and on button ) still nothing can someone please help thanks

Could be many things. Your charger port may be broken inside. Your battery could be stone dead and won't charge 1 bit. Your phone could have water or liquid damage and won't allow the device to power up at all due to a fried mother/logic board. The screen could be cracked underneath that you can't see, and won't allow it to show anything including a battery icon. I sell phones and repair them sometimes as well. I've seen all 4 of the ones I mentioned happen. Take to a cell phone repair shop and get an estimate.

  • Why is my iPhone 4's touch screen not working well? I have an iPhone 4, and has recently stopped working properly. When I unlock it, it will sometimes take at least 5 swipes to work. It's even worse when I try to put in my passcode. In the middle of playing a game or texting someone, the touch screen will stop working, and I can't tap. The home and power button still work just fine, but I need to power off and then back on again to get it working again. If anyone can help, it is greatly appreciated.
  • My iphone is not working as well as it used to? I have a kind of old iphone, a few years. And sometimes it just shuts me out of what I'm doing, will randomly make the screen black with white apple on it like I just turned it on when I haven't and it's charged, the circle button doesn't work that well, and the like. Is it time for me to upgrade?
  • Is my iPhone not working well because the screen is really cracked? Okay, so I have an iPhone 4S and it has been working perfectly fine until last night. It is really cracked and some pieces of the glass have fallen out (oops) but now the top part of my screen doesn't really work. The home button works fine, but the lock button does not. Also, I can still type although its a struggle but whenever something is more towards the top of the screen it is nearly impossible to click on. Is this because of the cracks or is something wrong with my phone?
  • Is Apple making their older phones not work well, again? Apple has been caught making (through updates) older devices operate slow (si people but newer products). Lately my older iPhone 5S that I use to surf the web and play using vua Wi-Fi has been acting up s little. I noticed it yesterday and today, Has anyone else noticed that their older Apple device is not performing as well as last month?
