If you've been experiencing slow Wi-Fi on your smartphone, the culprit could be your phone case. It turns out that certain materials used in phone cases can actually interfere with your Wi-Fi signal and affect your internet and app experiences.

The Impact of Phone Cases on Signal and Wi-Fi Speed

According to Tech Evaluate, a website that reviews tech products, some phone cases can absorb or block Wi-Fi and cellular signals, leading to slower internet speeds. While most case manufacturers take this into account, it's always worth checking what material your case is made of.

Metal cases, in particular, should be avoided as they can block the reception of the signal, as stated on the support page of smartphone manufacturer One Plus.

Wi-Fi signals are in the form of radio waves, which are electromagnetic. Metal is known to absorb these waves and weaken your Wi-Fi signal, hence the recommendation by Wi-Fi experts to keep metal away from internet routers.

Additional Considerations

Aside from avoiding metal cases, it's also important to steer clear of cases that can cause your phone to overheat. Overheating can lead to performance issues and further impact your signal and Wi-Fi speed.

Fortunately, most cases are made of materials like leather, rubber, plastic, or silicone, which should not have a negative impact on your signal or Wi-Fi speed.

If you're unsure about the compatibility of your phone case with your Wi-Fi signal, it's best to consult your phone manufacturer's website for device-specific advice and recommendations.
