How to Fix iPhone 7 Plus Not Charging Unless Restarted and Other Problems

by

The iPhone 7 Plus brought big upgrades like dual cameras and stronger performance, but even solid phones can run into frustrating issues.
Today we’re tackling problems like your iPhone 7 Plus not charging unless restarted, losing cellular signal, or overheating.

Here’s how to troubleshoot and hopefully fix them.

iPhone 7 Plus Only Charges After a Restart

Problem:
The phone refuses to charge unless it’s cold booted (power + volume down restart). Sometimes it keeps draining even while plugged in. The issue started after updating to iOS 11.

Solution:
Here’s what you should try:

  1. Swap out the charger and cable:
    • Use a different, preferably Apple-certified charger and Lightning cable.
  2. Clean the charging port:
    • Use a can of compressed air or a soft brush to clear any debris.
  3. Reset the phone software:
    • Backup your data (iCloud or iTunes).
    • Erase all content and settings via Settings → General → Transfer or Reset iPhone → Erase All Content and Settings.
    • Set up the iPhone as new (don’t restore yet) and check if the charging issue persists.

If the problem is still there after these steps, it’s likely a hardware issue (maybe with the charging IC or logic board).

  • Bring the phone to an Apple Store or authorized service center for deeper diagnostics.

iPhone 7 Plus No Signal in Certain Areas

Problem:
Sudden loss of signal — “No Service” shows up, especially in certain areas like Bulacan, while the same SIM card works fine in another iPhone 7 Plus.

Solution:
Since your SIM works in another phone and another SIM doesn’t work in yours, it points to a hardware issue — most likely the antenna or radio chip inside your iPhone.

You’ve already tried all the right resets (network settings, full restore).
At this point:

  • Bring the device to a certified service center.
  • You may need a repair or a full logic board replacement if it’s a radio chip failure.

iPhone 7 Plus Overheating, Freezing, and Poor Battery Life

Problem:
Persistent overheating around the camera area, short battery life, freezing screens, and audio volume issues while using apps like audiobook players.

Solution:
Here’s the best way to tackle this:

  1. Update all your apps:
    • Open the App Store → tap your profile icon → update all pending apps.
  2. Perform a full factory reset:
    • Backup everything important.
    • Go to Settings → General → Transfer or Reset iPhone → Erase All Content and Settings.
    • Set up your iPhone as new — don’t restore apps yet.
  3. Monitor the phone without any third-party apps:
    • Use it for 24–48 hours and check for overheating or freezing.

If the overheating continues even after a clean install, it points to internal hardware damage — possibly the battery or motherboard.

  • Get it checked by a technician — overheating can get worse and damage the phone permanently if left unresolved.

Final Tip

When troubleshooting major issues like charging failure, signal loss, or overheating, always test your iPhone clean — no apps, no old settings restored. That way, you’ll know if it’s truly a software problem or if hardware repair is needed.
