Since years it has been happening that smartphone makers have been using either polycarbonate material or glass at the back of smartphones to make wireless charging possible. That's because phones with metal backs hinder the connectivity, which makes a difference in experience and charging speeds. But interestingly, Google's recently launched Pixel 5 flagship smartphone comes with an aluminium back and still has wireless charging. It even bring reverse wireless charging onboard. So, how is it possible.

As it turns out, the Pixel 5 with aluminium back uses an extra layer called as ‘bio-resin', which is essentially a thin layer of plastic. This is the same material that you will feel once you hold the device. The aluminium part is just to make the back more durable instead of giving you a metal ‘feel' as mentioned by Android Authority. Hence, Google was able to pull it off. This tech let the firm cut a physical hole in the aluminium chassis and place a wireless charging coil. You won't be able to feel it since the resin layer is sturdy enough.

When asked that why didn't Google use glass or plastic at the back instead of the above solution, the firm said that it was the only way they could achieve the same footprint and thin-ness for the handset.

While this new solution opens up many possibilities for future smartphones as well and we may see more metal body devices supporting wireless charging, it is yet to be seen of the ‘bio-resin' material is as fragile as glass or stronger.
