While the Redmi Note 3 is linked to the Beats Pill 2.0 over Bluetooth, we observed a seamless connection up to 10 meters. After that, the connection started to fluctuate with a lot of audio disruptions.
To establish Bluetooth connection between the Beats Pill 2.0 and Redmi Note 3, first hold down the power button for a few seconds until the 'b' button starts blinking slowly. Then go to the phone's Bluetooth settings and select 'BeatsPill' to start pairing.
Given that a non Apple based smartphone like the Redmi Note 3 can support Apple's Beats Pill 2.0 is great although it can only manage a 10 meters Bluetooth range with the portable speaker.
