Remember when iOS 11 rolled out and many users complained about slow WiFi speed after updating their iPhone? Well, things haven’t changed much in 2018 either. iOS 12 update is now available to download for everyone, and unfortunately, it also has similar WiFi issues.
I have personally experienced slow WiFi speed on my iPhone X after installing iOS 12. What’s even worse is there’s no guaranteed fix or workaround to resolve the problem.
Just in case you are wondering, the problem isn’t with the WiFi router either. If you connect other devices to the same network, they’ll work fine. It’s an iOS issue which Apple appears to be incapable of fixing.
Anyway, below are a few tips you can try to fix slow WiFi speed on iOS 12.
