Bluetooth allows you to connect your wireless headphones and other devices to your phone easily. But Bluetooth interference can randomly disconnect your paired devices and make Bluetooth less reliable.
There are many different things that can interfere with your Bluetooth connections. In this post, we discuss whether phone cases can interfere with your Bluetooth devices.
Here’s Whether Phone Cases Interfere With Bluetooth:
Phone cases from reputed manufacturers won’t interfere with your Bluetooth headphones and other Bluetooth devices. Most phone cases use plastic, silicone, or other non-metallic materials. Such non-metal phone cases won’t affect Bluetooth. However, metallic phone cases can block Bluetooth signals and make them weaker.
Can Metallic Phone Cases Interfere With Bluetooth?
Metallic phone cases can interfere with Bluetooth and make your Bluetooth connections weaker.
Metals block all radio signals including Bluetooth, Wi-Fi, and cellular signals. So phone case manufacturers don’t make full metal phone cases.
However, some phone cases may use metallic parts, and those parts can sometimes make your Bluetooth connections less reliable.
Can Silicone Phone Cases Interfere With Bluetooth?
Silicone phone cases won’t interfere with Bluetooth. Silicone is not a metal, so it won’t affect your Bluetooth, Wi-Fi, or cellular signals.
Can Plastic Phone Cases Interfere With Bluetooth?
Plastic phone cases won’t also affect your Bluetooth signals. Plastic is not a metal, so it can’t make your Bluetooth, Wi-Fi, or cell signals weaker.
Can Magnetic Phone Cases Interfere With Bluetooth?
In theory, magnetic phone cases like Apple MagSafe cases can slightly degrade Bluetooth signals.
However, in practice, magnetic phone cases don’t usually cause any noticeable interference with Bluetooth signals.
Can Thick Phone Cases Slow Down Bluetooth?
Even thick phone cases only have a thickness of a few millimeters. So non-metallic thick phone cases won’t affect your phone’s Bluetooth.
On the other hand, metallic phone cases can make your phone’s Bluetooth weaker regardless of their thickness.
Can Phone Cases Affect Bluetooth Headphones?
Most phone cases won’t interfere with Bluetooth headphones.
None of the phone cases are fully metallic. Most cases use non-metallic materials like plastic and silicone.
So none of the cases from decent manufacturers won’t affect your Bluetooth headphones in any way.
What Can Interfere With Your Phone’s Bluetooth?
There are many different things that can interfere with your phone’s Bluetooth connections. These interference sources can randomly disconnect your Bluetooth headphones and cause crackling noises.
Other Bluetooth devices can interfere with your phone’s Bluetooth connections. If there are many Bluetooth devices nearby, all of them have to share the same 2.4 GHz Bluetooth band, causing weaker Bluetooth connections and random disconnects.
Wi-Fi also uses the same 2.4 GHz band as Bluetooth. So if you have many Wi-Fi devices nearby, they can also make your phone’s Bluetooth connections unreliable.
Cordless phones and wireless security cameras can also share the same 2.4 GHz band as Bluetooth. So they can also interfere with your Bluetooth devices.
Even microwave ovens can emit RF radiation in the 2.4 GHz band, causing interference to Bluetooth devices.
How To Reduce Bluetooth Interference
When you use Bluetooth headphones and other devices, you should move away from RF interference sources like other Bluetooth devices, Wi-Fi devices, cordless phones, and microwave ovens.
You should also keep your connecting Bluetooth devices closer to each other to get a stronger signal. Stronger Bluetooth signals are less susceptible to RF interference.
Most phone cases are non-metallic and won’t interfere with your Bluetooth devices.
All decent phone case manufacturers make sure that their cases won’t affect Bluetooth, Wi-Fi, or cellular signals.
So you don’t usually have to worry about Bluetooth interference when you buy your next phone case.
