How to Fix iPhone 7 Plus Battery Percentage Decreasing When Charging

The iPhone 7 Plus is one of Apple’s most iconic models — dual cameras, water resistance, and strong all-around performance. But even great phones can run into weird problems, like your battery percentage dropping while it’s supposed to be charging. If you’re facing this or other strange battery-related issues, this guide will help you troubleshoot and hopefully fix them.


iPhone 7 Plus Battery Percentage Decreasing While Charging

Problem:
Even when plugged in, the battery percentage keeps going down instead of up. Using different chargers, including the original Apple charger, doesn’t help.

Solution:
Here’s what you should try:

  1. Clean the charging port:
    • Use a can of compressed air to blow out any dust or debris.
    • A clogged port can prevent a proper connection.
  2. Use a different charging cable and adapter:
    • Even if you’ve already tried another charger, be sure it’s Apple-certified.
  3. Factory Reset:
    • Backup your data first (iCloud or iTunes).
    • Go to Settings → General → Transfer or Reset iPhone → Erase All Content and Settings.
    • Set up the iPhone as new, without restoring apps or settings yet.
  4. Observe the phone:
    • See if the problem happens before installing any apps.
    • If it charges normally when clean, the issue might be software or app-related.

If none of this works, bring your iPhone to Apple or a service center.
There could be a deeper hardware issue, like a bad battery or charging chip.


iPhone 7 Plus Static Noise During Calls

Problem:
During phone calls, the person on the other end hears static and can’t understand you — but you hear them fine.

Solution:
First, check if it’s a location or network issue:

  • Try making a call from a completely different location.

If the static persists:

  1. Set up the iPhone as new:
    • Go to Settings → General → Transfer or Reset iPhone → Erase All Content and Settings.
    • Don’t restore from a backup yet — test it fresh.

If you still have static after resetting, the problem is likely hardware-related.

  • Contact Apple support or your insurance provider about getting another replacement device.

iPhone 7 Plus Won’t Fully Charge and Reboots on Incoming Calls

Problem:
The iPhone shows it’s charging but never reaches a full charge. It also randomly reboots when receiving a call or text.

Solution:
Here’s how to troubleshoot it:

  1. Clean the charging port with compressed air to ensure a solid connection.
  2. Factory reset the phone:
    • Backup your data.
    • Erase all content and settings through Settings → General → Transfer or Reset iPhone.
  3. After resetting, don’t install anything yet. Test the phone in its “clean” state.

If the problem still happens, chances are you’re dealing with a bad battery or hardware issue.

  • Bring the phone to a service center for battery diagnostics or replacement.
