How to Fix iPhone 15 Wi-Fi Problems
If you’re seeing slow Wi-Fi speeds and/or dropped Wi-Fi connections, here are some potential fixes that have worked for us and others in the past.
Before you start messing around with your phone’s settings, investigate the Wi-Fi connection causing problems. If you’re on your home Wi-Fi network, try restarting your router.
If you’re confident there aren’t issues with the router itself, check Down Detector and see if others with the same internet provider are having similar issues in your area.
If you can’t access the router your iPhone 15 is connected to, or if you’re positive the issue has nothing to do with your ISP/router, head into your iPhone 15’s Settings app.
Once you’re in there you’ll want to forget the Wi-Fi network you’re having issues with. Here’s how to do that:
- In the Settings app, tap Wi-Fi
- Select your connection by tapping the “i” in the circle
- Tap Forget this Network at the top of the screen. This will cause your iPhone to forget the Wi-Fi password so you’ll want to have that handy
If this doesn’t work, try resetting your iPhone 15’s Network Settings:
- Go to your Settings app
- Tap General
- Tap Transfer or Reset iPhone
- Tap Reset
- Tap on Reset Network Settings
If none of those help, you’ll want to check out Apple’s guide to Wi-Fi problems.

- Tap “Forget this Device”
- Try reconnecting to the Bluetooth device
If that doesn’t work, you can try resetting your iPhone’s Network Settings:

- Tap Transfer or Reset iPhone

- Tap Reset Network Settings
You can also try reverting back to your iPhone 15’s factory default settings to see if that helps. This should only be done as a last resort. Here’s how to do it:

How to Fix iPhone 15 Charging Problems
Some iPhone 15 users are running into charging issues and most of the problems are related to wireless charging.
If you encounter an issue with wireless charging, you should try hard resetting your iPhone 15.
If you’re using an iPhone case to store credit cards or security passes, you’ll want to remove those before charging your phone. You also might try taking your case off and try charging your iPhone 15 that way.
If you own a BMW, and Apple Pay and other NFC features become unavailable after wireless charging, you’ll want to make sure your device is running iOS 17.1.1 or newer. iOS 17.1.1 resolved these issues.

Your iPhone 15’s speakers should provide you with loud and crisp audio. If the sound starts to crackle or sound muffled, here are a few things you can try before getting in contact with Apple customer service.
