Bluetooth Problems and Troubleshooting

Bluetooth is a type of technology that links various electronic devices to each other over a limited distance. Typically this is over a range of 10 meters, using low-power radio communications. These devices use Bluetooth protocols as the medium of communication. As many believe, Bluetooth is not a replacement for Wi-Fi. Being a relatively new to technology, many are confused about what Bluetooth means and how it works. Below Experts answer Bluetooth questions and address the issues many users face.

How much power does Bluetooth consume on a typical cell phone? Does it justify being turned off when not in use?

Take an iPhone 4S for example, which uses state-of-the-art Bluetooth 4.0 technology. It now consumes peak energy of 15mA as compared with earlier Bluetooth versions which went to 25mA. Furthermore, when at idle it consumes no power at all that makes it an immense power-saving device. This means that any device installed with Bluetooth 4.0 may be left on without any battery drain. Refer to the table below which provides a comparison of the specification: bluetooth specs

If the problem is solved all the keys should respond and the device should be able to change to the other modes.
