Wireless charging is cool in concept and as a technology, but it’s not quite practical. Wireless charging essentially allows you to charge your device without having to connect any cables. This is convenient for people who use their phones with two hands while waking up in bed, or for couples where the phone is on your partner’s side. There is no significant purpose or “ease-of-use” to wireless charging. Instead, wireless charging delivers a product that is poor, and not very useful in the end.
The technology uses the NFC antenna on the back of enabled devices, which means that energy transfer is slow, and can be slower than expected if the device is mal-aligned causing magnetic drop-outs, where the magnetic resonance can not be detected by the NFC antenna. The biggest shortfall of this technology is that the battery can not be charged over 70%. Upon reaching that battery level, you will have to plug in your phone the old fashioned way. Use of NFC is disabled when the device is undergoing wireless charging, for obvious reasons. Although, not the most significant inconvenience for some, it could pose problems for those looking to conserve space. You will need to purchase a separate device, connected by a cable, to charge your phone. These devices are not the cheapest.
Increase in cost of production with no specific benefits, except for making your mornings 1.27% easier to bear, does not justify (in my opinion) wireless charging in such a device. The BlackBerry Z30 will be the first BlackBerry 10 smartphone to incorporate this technology. Apple Inc. has scrapped any idea to introduce wireless charging to their smartphones as they understand the limitations of such technology, and how it does not ameliorate the customer’s experience.
