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:
- 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.
- Use a different charging cable and adapter:
- Even if you’ve already tried another charger, be sure it’s Apple-certified.
- 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.
- 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:
- 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:
- Clean the charging port with compressed air to ensure a solid connection.
- Factory reset the phone:
- Backup your data.
- Erase all content and settings through Settings → General → Transfer or Reset iPhone.
- 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.
