iPhone won't turn on after battery replacement.

My iPhone won't turn on after battery replacement. I have looked many places and tried many things.

Story:

My iPhone broke so we bought a cheap one from online, took the phone apart and put the battery following a guide exactly except I mixed up the battery casing and screen connector casing screws so I sorted those out as best I could and put it back together. Nothing, screen didn't work, couldn't get any response from the vibrator, after a long charge same thing, except I did feel the phone warm while it charged. Thought it was a defective battery and bought a good one from iFixIt. Replaced it and was extra carful to make sure this time was errorless Put it back together, screen didn't turn on again, same issue. Charged for a couple hours, nothing didn't even warm up the phone, no iTunes response either.

Facts I’m pretty sure of:

  1. Battery is ok (came from iFixIt)
  2. Battery to charging port is ok (First battery warmed the phone (second battery was probably full))
  3. Screen is possibly not broken (Not getting a response from anything not even the vibration so that doesn't mean it's just the screen)

Things I've already tried:

  1. Quadruple check that all cables connectors are securely in place.
  2. Let it charge for a while
  3. Pressing Power and Home buttons for 10+ seconds, and home for 3 then
  4. Tried unplugging battery and plugging into iTunes
  5. Tried disconnecting the battery and reconnecting

Not tried:

  1. Screen replacement
  2. 3rd battery
  3. Any other motherboard part replacements

Any and all suggestions appreciated!

Problem found!

It was the screen, I must have damaged it while replacing the battery.

Can you plug it into a computer and see if anything shows up? That might help diagnose if this is a screen issue or a battery issue.

I plugged it in with 0 response, no sounds or anything.

Do you know if the battery in the “used” phone was charged or not? It is possible that it is fully depleted. You could measure the voltage of the battery directly with a multimeter. A normal battery is ~3.8V, fully charged at 4.2V and the phone will not boot if it is below ~3V.

I’m also a little bit concerned about you mixing up the screws on the Screen bracket. Putting a long screw in the wrong hole can cause Long Screw Damage although in this case, your immediate symptoms don’t correspond.

4.4V when I tested the battery from iFixIt. 0.1V from the cheap one I bought first.

4.4V seems a bit high but that could be a meter effect.

Connect the phone to an iTunes enabled computer. Then shine a bright flashlight on the screen. Do you see a dim image or does iTunes recognize the phone?

by

Neither light or iTunes.

Okay, then that eliminates a lot of potential issues. Ideally, you need to try a known-good battery (one from a working phone or trying your battery in a known-good phone) to eliminate that completely (batteries can be a pain!).

Otherwise, I am still concerned about your mixing up of the screws. Look inside the standoffs on the logic board. If you see something like this.

by

After trying these and getting out another old iPhone 5s that I have and switching batteries and screens and every combination I found out that it was the screen. Apparently I damaged it in the process of fixed the phone. Not sure what's next or how to fix it. But now I know the source of the problem! (go ahead and make a new answer if you want to help fix the screen).
