How does the Google Pixel 5 charge wirelessly if it has a metal body?

The Google Pixel 5 has just been released, along with some very cool new products from the search engine giants (like a new Chromecast dongle). The Pixel 5, of course, packs a ton of improved features and capabilities, in addition to Google’s standard Android experience, and now, you get wireless charging too (missing from the Pixel 4a).

However, a great question is: How does wireless charging work with the aluminum body of the Pixel 5? In some context, wireless charging doesn’t work as well on metal surfaces, and most Qi-compatible smartphones use glass backs as a result. Metal reduces the efficiency of the charging mechanism, and this can also result in high device temperature, which is never good for computers (even mobiles).

Despite that, Google has equipped the Pixel 5 with Qi-certified wireless charging, though you’ll need to purchase the charger separately. For wireless charging to work, the company designed the Pixel 5’s aluminum body with a physical cutout above the charging coil. Basically, the new flagship Pixel smartphone has a small hole in its body.

However, you will not be able to see this hole. According to David Imel of Android Authority, Google covered the body of the smartphone with bio-resin (a form of plastic), so the hole in the aluminum body is hidden and protected from the elements by the layer. Google promises that bioresin is a durable material, so you won’t be able to feel the coil either.

This is also the largest battery in a Pixel phone, with a 4,080 mAh battery under the hood. However, the use of bioresin as a protective layer also helps maintain the Pixel 5’s slim profile – just 7.62mm. Personally, it’s a relief to see a bigger battery on the Pixel 5, and just under 4,000 mAh on a flagship device is just unacceptable in 2020.

So what do you think? Google’s unique workaround certainly opens many doors for smartphones in the future. While glass bodies are popular for their premium finish, they can certainly add to the cost of a smartphone. Now that there is a way to have wireless charging Y metallic bodies, we could see wireless charging becoming more available on affordable smartphones.
