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:
- Swap out the charger and cable:
- Use a different, preferably Apple-certified charger and Lightning cable.
- Clean the charging port:
- Use a can of compressed air or a soft brush to clear any debris.
- 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:
- Update all your apps:
- Open the App Store → tap your profile icon → update all pending apps.
- 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.
- 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.
