After three years of Apple products, Target is moving to Android devices for stocking, pulling items, and other essential sales floor duties. Target first outfitted its employees with Apple products in 2014, replacing PDAs with iPod Touches. Gizmodo reports: In Fall of 2016, Target stores began testing the Zebra TC51, which runs Android 6.0 Mashmallow and was confirmed to Gizmodo as "the new MyDevices for store team members chainwide" by a company spokesperson over email. On Reddit's r/Target page and the unofficial employee forum The Breakroom, the new devices have been met with enthusiasm -- and plenty of jabs at the old iOS scanners. "The current iOS my devices we have all sorts of issues, connection issues, scanner issues, and tons more," one Breakroom poster complained. On Reddit, a former store manager wrote that "the iPod hardware they used as on the floor scanners for employees died quickly and there was no way of swapping in new batteries. There were many hardware issues that came about with the ipods." While a Target spokesperson confirmed the company will still purchase some products from Apple -- iPads for online order pickups, iPhones for managers -- the sales floor is switching to Android, and the company is staffing up on Android developers to port over all the internal software stores use.

One little detail Apple didn't mention at its event in Cupertino, California yesterday was the fact that the new iPhones will support fast charging. According to the official tech specs page, the new iPhones can recharge up to 50 percent of their battery life in a 30-minute charge. The catch? You have to use a USB-C charger and Lightning cable (sold separately). 9to5Mac reports: iPhone 8 battery life is roughly equivalent to the iPhone 7 and iPhone 7 Plus. On a full charge, expect up to 12 hours of internet usage on iPhone 8 and iPhone X, with up to 13 hours on iPhone 8 Plus. With a 50% quick charge in 30 minutes, you are effectively gaining hours of additional battery life during the day, even if you only plug in for a short period. However, to take advantage of fast-charging, you cannot use the Lightning to USB-A cable that is bundled in the box. Fast charging requires a USB-C to Lightning cable and the USB-C wall charger. More specifically, one of three USB-C wall chargers. Apple sells 29W, 61W and 87W variants of its USB-C power adapters. Prices range from $49 to $79. Apple doesn't break out specific numbers on how each model affects charging times, it's not clear if the cheapest 29W model can achieve the advertised 50% recharge in 30 minutes.

An anonymous reader quotes a report from Electrek: At the Frankfurt Motor Show (IAA Cars 2017) this week, Samsung's battery division, Samsung SDI, showcases a new "Multifunctional battery pack" solution to enable more range in electric vehicles as the Korean company tries to carve itself a bigger share of the growing automotive battery market. Most established automakers, like Nissan with the LEAF or even GM with the more recent Chevy Bolt EV, have been using large prismatic cells to build their electric vehicle battery packs. Tesla pioneered a different approach using thousands of individual smaller cylindrical li-ion battery cells in each pack. Earlier this year, Samsung unveiled its own '2170' battery cell to compete with Tesla/Panasonic. Now they are claiming that they can reach an impressive energy density by using those cells in new modules: "'Multifunctional battery pack' of Samsung SDI attracted the most attention. Its users can change the number of modules as they want as if they place books on a shelf. For example, if 20 modules are installed in a premium car, it can go 600 to 700 kilometers. If 10 to 12 modules are mounted on a regular sedan, it can run up to 300 kilometers. This pack is expected to catch the eyes of automakers, because they can design a car whose mileage may vary depending on how many modules of a single pack are installed."

A lawsuit (PDF) filed Tuesday in U.S. District Court in Oakland, California, recounts the frustrations of five plaintiffs who found that Apple's Powerbeats 2 and Powerbeats 3 headphones did not perform as advertised. They are also claiming the company is refusing to honor warranty commitments to repair or replace the failed units. The Register reports: The complaint seeks $5,000,000 in damages and class action certification, in order to represent thousands of similarly afflicted Beats customers who are alleged to exist. "In widespread advertising and marketing campaigns, Apple touts that its costly Powerbeats (which retail for $199.95) are 'BUILT TO ENDURE' and are the 'BEST HEADPHONES FOR WORKING OUT,'" the complaint says. "But these costly headphones are neither 'built to endure' nor 'sweat & water resistant,' and certainly do not have a battery that lasts for six or twelve hours. Instead, these shoddy headphones contain a design defect that causes the battery life to diminish and eventually stop retaining a charge."

The complaint attributes the shoddiness of Apple's Powerbeats headphones to cheap components. Citing an estimate in a recent Motley Fool article, the complaint contends that Apple's Beats Solo headphones cost $16.89 to make and retail for $199.95: a markup of more than 1,000 per cent. That figure actually comes from a Medium post by Avery Louie, from hardware prototyping biz Bolt.

At its Ryzen Pro event in New York City last month, AMD invited a French company called Qarnot to discuss how they're using Ryzen Pro processors to heat homes and offices for free. The company uses the Q.rad -- a heater that embeds three CPUs as a heat source -- to accomplish this feat. "We reuse the heat they generate to heat homes and offices for free," the company says in a blog post. "Q.rad is connected to the internet and receives in real time workloads from our in-house computing platform."

The idea is that anyone in the world can send heavy workloads over the cloud to a Q.rad and have it render the task and heat a person's home in the process. The two industries that are targeted by Qarnot include movies studios for 3D rendering and VFX, and banks for risk analysis. Qarnot is opting in for Ryzen Pro processors over Intel i7 processors due to the performance gain and heat output. According to Qarnot, they "saw a performance gain of 30-45% compared to the Intel i7." They also report that the Ryzen Pro is "producing the same heat as the equivalent Intel CPUs" they were using -- all while providing twice as many cores.

While it's neat to see a company convert what would otherwise be wasted heat into a useful asset that heats a person's home, it does raise some questions about the security and profitability of their business model. By using Ryzen Pro's processors, OS independent memory encryption is enabled to provide additional security layers to Qarnot's heaters. However, Q.rads are naturally still going to be physically unsecured as they can be in anyone's house.
