Nokia Shows What’s Next in Wireless Charging
The recent debut of Nokia’s Lumia 920, the first smartphone to feature native wireless charging, has some people pretty wired over the idea that the rest of the industry will soon go cordless, too, as the Lumia draws draw more attention to wireless charging and pushes others to follow the lead.
Not that Nokia has completely mastered the issue: So far, the phone can only be wirelessly powered by a select few Nokia-produced or third-party chargers. Nevertheless, the Lumia has set a new standard for phone charging.
“Wireless charging will become more commonplace in the next few years, though it still needs to come down in price for it to replace the more ubiquitous — and free — wall chargers,” says Devindra Hardawar, a national editor with VentureBeat. “The new Lumia line is definitely the biggest push we’ve seen for the feature so far.”
What’s Next in Wireless Charging
So what now? The biggest promise seems to be in coupling devices together to wirelessly charge. Intel recently partnered with Integrated Device Technology (IDT) to develop a new wireless charging technology (WCT) concept that will allow smartphones to be charged via laptops by activating a detection software and placing the smartphone about an inch away from the laptop. According to Intel, it will take about an hour to achieve a full charge on your phone. The company plans to deliver the full chipset by early 2013.
“The first phones with Intel processors on broad release were based very closely on the Intel reference design,” says industry consultant Daniel Nye Griffiths. “So a reference design with inductive [wireless] charging built in might be an interesting proposition.”
Until the device makers cut the cord, consumers still need to get the most out of their devices between charges. Here are a few tips — from Mini Physics, Apple, and DigitalTrends — on how to extend battery life through the workday:
- Turn your phone off when it’s charging. Charging devices while they’re on leads to a “parasitic load,” where the charger is unsure of what to do with the extra load your device is burdening it with while it’s on.
- Don’t expose it to extreme high or low temperatures. Intense heat will degrade battery performance quickly. The same goes for freezing temperatures.
- Avoid frequent deep-cycle discharges. This is when you let your phone’s battery drain down to 5-20 percent and then charge it back up to 100 percent. Lithium ion batteries do not do well with this practice.
- Select a dark background screen. This is especially for users with screens that don’t use power to display black pixels: The obvious solution is to make sure you have as dark a background as possible.
- Shut down apps and other power-hogging features you aren’t using. Many mobile devices allow you to manage your applications and stop those that are running, like push notifications and music players. Turning off GPS, Bluetooth and Wi-Fi helps save some juice, to.
- Keep phones locked. Running a smartphone unknowingly uses battery life. So lock it. You can still receive calls, emails and text messages on your screen, but nothing will happen until the phone is unlocked.
