Summary:

Can a new logo and catchy name add some juice to a wireless charging group? That’s the hope of Rezence, the new brand of the A4WP, or Alliance for Wireless Power.

Consumers no longer have to remember what A4WP stands for — it’s the Alliance for Wireless Power, for the curious — thanks to a new brand name and flashy logo. The wireless consortium now goes by the name Rezence, which is a little more consumer-friendly.

Rezence boasts around 70 members, including heavy-hitters Intel, Samsung, LG and Qualcomm, which is actually a member of all of the major wireless charging groups; it hopes to blend the best of all the technologies and push a more uniform standard. Until that happens, Rezence will continue to compete against the Wireless Power Consortium and the Power Matters Alliance.

One key benefit Rezence technology offers over my current wireless charging preference — I use products with the Qi standard for my iPhone 5s and other devices — is support for multiple device charging on a single surface. I like that feature as you don’t have to place a phone on a specific place; you can just drop a device, or devices, on a charging surface and the battery starts refilling.

It’s also worth noting that the Bluetooth SIG decided to partner with Rezence over its competitors in October. The idea here is that Bluetooth support could make the charging experience more efficient as devices could actually communicate with the charging pads.

  1. Until wireless power is as efficient as wired, I don’t really see the point. Since wireless power will never be efficient, these industry groups should come together and develop a standard for wired power that works by playing your phone on a surface. Like those new Lumias that have the little metal dots on the back, which allows the use of a Qi-compatible back cover — those little dots could just plug right into corresponding dots on a charging pad. Alignment problems could be solved using magnets. Such a system wouldn’t have the efficiency problems (slow recharge times, battery-killing excess heat) of a wireless system. Why doesn’t this already exist?

    1. In real world use I’m not finding the efficiency gap to be an issue. Everyone’s situation is unique, of course but here’s mine.

      All night long, my phone sits on a wireless charger. No matter what, I have a full charge to begin the day. When I’m sitting at my office desk, the phone is again on a wireless charger. Obviously, when I’m away from the charging pad, the battery will be running down, but anytime I’m near it, the phone is charging at around a 70% rate.

      In as little as 4 hours a dead device can be fully charged. Since going wireless for charging, my phone battery has never been below 40% because when it’s not in use, it’s charging. Again, that’s my very specific use case which doesn’t apply to all. But I really don’t see the inefficiency as that big of a problem.

    2. That already exists; try searching for inpofi or duracell mygrid.
