This wireless charging receiver chip could end up in your next smartphone

Wireless charging is taking off, but it still requires you to place a device on a charging pad. Soon, however, wireless charging may be truly wireless — allowing you to charge a device while you carry it around your house thanks to base stations that would be located around the home.

Energous is one of the biggest names when it comes to developing a truly wireless future, and the company debuted its original WattUp wireless charging tech last year. Now, it’s working to make that tech even more accessible thanks to the launch of the new DA2223 receiver chip, which is designed for small electronic devices like smartphones.

The chip itself measures 1.7 x 1.4 x 0.5 mm, making it a fraction of the size of even a coin. The chip doesn’t work alone, but according to Energous, depending on the power level of the device it’s being used in, the chip can be coupled with a matching circuit from two standard discrete components and a small antenna — which will make for a complete wireless charging receiver. In other words, the components required for true wireless charging are more than small enough to fit inside a smartphone.

So when should we expect to see chips like this show up in smartphones? Well, that remains to be seen. Apple was rumored to be working with Energous for the launch of recent smartphones, but so far no iPhone has featured Energous tech. Not only that, but including a receiver inside a smartphone is only one part of the equation; users will also need to install charging stations around their home, and businesses might want to do the same.

Earlier this year, Energous announced its Wireless Charging 2.0 tech, which it said allowed for truly wireless charging in a 15-foot radius around the wireless charging station. Generally speaking, the closer you are to a charging station, the quicker a device will charge.

One thing that Energous does promise is interoperability between wireless charging devices, which means a wireless charger built by Samsung will work with an Apple device, and vice versa. In other words, Energous is aiming to create a new standard that it can sell to manufacturing partners.

Your next smartphone might have an Intel processor — seriously

When you buy a smartphone today, chances are it has a processor from Apple, Qualcomm, or maybe even Samsung. But what about Intel? Yes — the same Intel that's responsible for laptop and desktop PC chips. As crazy as it may sound, that's likely happening in the very near future.

On April 12, Intel announced it's entering a "multigeneration agreement" with ARM to create mobile SoCs (systems on chips) with Intel technology. In other words, Intel is partnering with ARM to create mobile chipsets.

The Samsung Galaxy A54 is Samsung's latest addition to its excellent midrange A-series smartphones. While we've yet to spend a good amount of time with it, we're optimistic this cut-price king is likely to be a great option if you want a smartphone for just $450. But what does the wireless charging situation look like?

A lower price often means some features end up on the cutting room floor, and wireless charging is often one of those features first on the cost-saving block. If you're a fan of the convenience of wireless charging, you'll want to make sure your new phone supports your favored charging method. So, does the Samsung Galaxy A54 have wireless charging?

The iPhone 15 may finally get reverse wireless charging — but I don’t want it

It’s been rumored that Apple has been working on implementing reverse wireless charging for a while. In fact, Apple has added some necessary components for making reverse wireless charging possible ever since the iPhone 12 (think of the MagSafe Battery Pack). Reports had actually suggested Apple was going to add it to the iPhone 14 and iPhone 14 Pro devices, but it failed to meet the deadline.

According to recent developments, reverse wireless charging, also known as bilateral wireless charging, is something that engineers at Apple continue to work on. It’s also been suggested that Apple’s version may be more advanced than what Android competitors offer. Maybe it’s just been delayed, and it may make its debut with the iPhone 15. Or perhaps it can go the way of AirPower and just be scrapped completely.
