How to Fix iPhone 6 Plus iTunes 4013 Error and Other Power Issues

If your iPhone 6 or 6 Plus is overheating, rebooting, stuck with a black screen, or throwing iTunes 4013 errors, you’re not alone. Power issues like these are frustrating, but they often have specific causes — and sometimes solutions you can actually do yourself.

Below, we break down real-world problems reported by users and how you can troubleshoot them.


iPhone 6s Plus Overheating After Startup (Reported by Raphael)

Problem:
Raphael’s iPhone 6s Plus gets extremely hot in the upper right corner seconds after turning on — but stays cool if it’s in Airplane Mode. Factory resets didn’t fix the issue. It only started after dropping the phone and updating to iOS 10.

Solution:
Since the overheating only happens when the phone tries to connect to a network, and it stays cool in Airplane Mode, this points to a hardware failure triggered by the drop — not a software glitch.

Most likely causes:

  • A damaged battery or connector
  • A shorted screen cable or motherboard component near the screen connector

Since a full reset didn’t help, the only real fix is a hardware repair.
Take it to a professional technician to properly diagnose the parts needing replacement. Do not keep using the phone in this state — overheating can permanently damage internal components.


iPhone 6 Keeps Rebooting, Won’t Complete Restore (Reported by Cash)

Problem:
Cash’s iPhone 6 randomly reboots during restore attempts. It had previous battery issues (sudden drops, erratic charging) even after a battery replacement.

Solution:
The random rebooting during restore suggests a hardware issue, specifically with the Power Management IC (integrated circuit) on the motherboard.

  • This chip regulates power distribution. If it fails, your iPhone becomes unstable no matter what battery you use.
  • Symptoms: sudden reboots, unstable charging, failure to complete restores.

Unfortunately, this isn’t something you can fix yourself.

  • Take it to Apple or a trusted repair technician for motherboard-level service.
  • Be ready: depending on the damage, the cost of repairing a motherboard issue may not be worth it compared to replacing the phone.

iPhone 6 Black Screen, Won’t Turn On (Reported by Amgrassi)

Problem:
Amgrassi’s iPhone showed a black screen and wouldn’t power on, even after multiple iTunes restore attempts. The phone buzzed when plugged in but the screen stayed dark.

Solution:
Here’s a quick checklist to rule things out:

  1. Force restart the phone:
    • Hold the Power + Home buttons together for at least 10 seconds.
  2. Charge for at least an hour using a known good Apple charger.
  3. Inspect the Lightning port for damage or debris.
  4. Try another charging cable and adapter.

If none of that works, you likely have a hardware problem:

  • Could be a dead screen, bad battery, or even motherboard failure.

Next step: Bring the iPhone to Apple or a qualified repair center for full diagnostics.


iPhone 6 Plus iTunes 4013 Error After Battery Swap (Reported by Monica)

Problem:
Monica’s iPhone 6 Plus started swelling batteries and showing iTunes error 4013 during restore attempts after screen and battery replacements.

Solution:
iTunes error 4013 typically means there’s a hardware communication problem between your iPhone and the computer.
It could be:

  • A bad USB cable
  • A faulty USB port on your computer
  • A bad charging port on the iPhone itself
  • A motherboard issue (especially if tampered repairs were done)

Here’s what to try:

  1. Use a different Lightning cable and USB port on your computer.
  2. Try restoring on another computer with the latest version of iTunes.
  3. If the issue persists, it’s likely internal hardware damage — especially given the history of third-party battery replacement and swelling.

Bottom line:
You’ll need a professional to open and inspect the device. If major components like the motherboard are damaged, the repair cost might be high — weigh that against simply replacing the phone.
