So your remote control just stopped working. Now use your smartphone to test batteries of the remote control. A short trick. It will tell you whether your battery is dead or not.The basic requirement to test your phone battery is a phone with a camera. Even better if you have a front cam too.

For users with a front camera

: Turn on the front camera.Point your TV remote at the front camera.You must be able to see the IR Blaster of remote, ‘the bulb thing in front of remote’. Now press any button on remote. If the ‘bulb’ is turning on and off in camera your batteries are fine.

For users with Rear Camera:

Same procedure. Turn on the camera on your phone. You all have seen the IR blaster (the “bulb” in front of remote).Now suppose you want to take a picture of the “Bulb”. So point your camera towards that bulb. Now press any key on remote and check whether the “bulb” blink or not.

Reason:

Now why we aren’t able to see that IR blaster turning in and off without a camera. As the name suggests, the IR blaster works in the infrared region of electromagnetic spectrum.The human eye is not able to see in that spectrum band. But our phone camera can. Many other professional cameras can also be used to see the same.
