HP HSTNN-UB1A Battery

We're still dependent on the venerable lithium-ion cell, first commercialized by Sony in 1991; it's light, safe and holds a lot of charge relative to most alternatives, but it isn't getting better fast enough to keep up with our growing electronic demands.

So instead, manufacturers are doing their best to "cheat'' their way around lithium-ion's limitations. The CES gadget show in Las Vegas last week featured plenty of workarounds that aim to keep your screen lit longer.

Proceed with caution, though: Manufacturer claims of battery life improvement can fall short of real-world experience.Not that long ago, computer-chip makers competed to make their chips ever faster and more capable, with power consumption a secondary consideration. But the boom in energy hungry smartphones and laptops means that companies like Intel need to put much more emphasis on power efficiency these days.

Intel says its sixth-generation Core chips, known as Skylake, add a little more than an hour to battery life to laptops compared with the previous generation, according to spokesman Scott Massey. The chips utilize a more compact design, hard-wired functions that used to be run via software and fine-tuning how they ramp power use up and down.

HP says the Spectre x360 notebook it introduced in March gains up to 72 minutes of battery life, for a total of up to 13 hours, thanks in part to Intel's new chip. Among other tricks, the PC doesn't refresh the screen as often if the image isn't moving. "If we can solve a bunch of small problems, they can add up,'' HP vice president Mike Nash said.

Similarly, Lenovo's new ThinkPad X1 Yoga tablet turns off its touch screen and keyboard backlight if it senses its owner is walking and has the screen folded back like an open book. Vaio, the computer maker formerly owned by Sony, says its Z Canvas launched in the U.S. in October benefits from shrinking components and efficiently distributing heat to make more room for a bigger battery.

And Dell says it has worked with manufacturers to squeeze more battery capacity into the same space. It says its efforts recently boosted the energy storage of its XPS 13 laptop by 7.7 percent compared to an earlier version of the same model .

Maybe it's your phone that's not keeping up. If so, you might check out new accessories designed to make it easier and faster to charge back up.Driven by the ever-increasing reliance on batteries, huge amounts of time and money are now being invested in building a successor to lithium-ion. Scientists at the University of Cambridge claimed a huge breakthrough last year in the development of a “lithium-air” battery that they claim could have 10 times the capacity of today’s lithium-ion technology. By using electrons partially from oxygen in the air, rather than those stored at one end of the battery, it promises enormous advances in capacity – enough to drive an electric car from London to Edinburgh on a single charge. The idea for lithium-air designs, which the Cambridge scientists describe as the “ultimate battery”, has been around for decades, but traditional lithium-peroxide designs have proven unstable, and incapable of surviving multiple recharges. A new chemical makeup, instead using lithium hydroxide, resulted in fewer chemical reactions draining the battery, and has been re-charged more than 2,000 times. Researchers from the Argonne National Laboratory in Illinois claimed a separate breakthrough last week, revealing a lithium-superoxide battery that it said solved many of the major problems of other lithium air batteries. Commercial application of these ideas, however, is expected to be years away, possibly at least a decade.

An alternative solution could lie not in better batteries, but better ways of powering them. Intelligent Energy, a British company based in Loughborough, claims to be pioneering the use of hydrogen fuel cells in consumer electronics. Henri Winand, the company’s chief executive, says that prototypes of his technology can be used to power a smartphone for a week, or a drone for several hours rather than 30 minutes. Instead of having to be recharged, fuel cells would be interchangeable, swapped in and out when needed. The company is also working with Suzuki on powering fuel cell scooters, and has signed an agreement with an unnamed “emerging” smartphone manufacturer to use its technology.

“We’re not going to have to plan our lives around the plug,” says Winand, who says fuel cell-powered smartphones could be as close as 18 months away. But for many consumers and companies that rely on battery power, this is not fast enough, or will at least take years to reach mainstream adoption. In the meantime, technology companies are betting on lithium-ion being the technology of choice for the foreseeable future.

Tesla, the electric car company run by the PayPal billionaire Elon Musk, expects to be one of the biggest consumers of batteries in the world. It is spending an estimate $5bn (£3.5bn) on a lithium-ion battery “gigafactory” in the Nevada desert. Many consumer electronics companies, instead of relying on a breakthrough, are working on technologies such as wireless charging, or fast charging, which can bring a battery from empty to 60pc full in half an hour.

Most of the likely candidates to replace our current batteries will still require years of testing and legal approvals to make it into cars or phones. Whoever wins that race, however, will have made one of the breakthroughs of the century. It's enough to make you want to drop everything and race for the nearest power outlet: Your workday isn't even done, and your smartphone or laptop battery is already in the red zone. If you're hoping that techno-progress will dispel that depleted feeling, you may be in for a long wait. Battery life is constrained by limitations in chemistry, and improvements aren't keeping pace with demands from modern gadgets.Speaking of premium – that’s where Moshi is targeting its next product, a new flagship set of on-ear headphones. Called the Avanti, Moshi is continues with the vegan leather, combining it here with a stainless steel band. Inside, Moshi has used a pair 40mm drivers for quality sound. You can connect the Avanti with a removable audio cable – the in-line remote works with any smartphone. Headed for store shelves sometime this spring, Moshi is expecting to charge $200 for the Avanti headphones.

The accessories company also had a trio of USB-C accessories to show off – a standard USB-C to USB-C cable will run you thirty dollars, while a USB-C to HDMI adapter will run you $40. The top of the USB-C trio belongs to Moshi’s new USB-C Multiport adapter, at $79. It features an HDMI port like the last cable, but also a standard USB 3.0 port as well as a USB-C passthrough port for charging your laptop or tablet at the same time. The first two cables will be available later this month, while the Multiport Adapter will ship this March.

Finally, to carry all these products in, Moshi showed off their new line of Helios backpacks: the Helios, which holds up to 15-inch laptops, and the Helios Lite, which will carry a 13-inch model. These new bags are pretty sleek, offering you a ton of space with a fresh, modern design. Each bag is built out of water-resistant fabrics, with more of Moshi’s “vegan leather” serving accent duty. You’ll be able to score the Helios Lite in either blue or grey for $120, or the bigger Helios, in either black or a rich brown, for $150. Both backpacks ship in March.

Smartwatches, smart homes, smart cars, smart headsets that promise virtual worlds -- this was the CES where every type of device decided to go smart. Computers have always seemed pretty smart on their own, and CES 2016 brought a wide selection of new systems, upgraded versions of old ones, and even a few radically new ideas.

The wireless-charging technology Qi makes it possible to charge a phone without plugging it in. Instead, you lay it down on a special pad and let electromagnetic field coupling do the work. Wireless charging has always been much slower than wired, although Qi's backers say it's speeding up. But wired charging is getting faster, too, at least for phones with the latest hardware - and with Qi, you still have to line up your device just right on the sometimes fussy pads. Lenovo ahead of CES 2016 has unveiled several new devices it will launch at the trade show. The Chinese consumer electronics giant introduced 12 new laptops, an all-in-one system, a tablet, a monitor, two 2-in-1 laptops, two ThinkCentre-in-one systems, apart from a new budget laptop with Chrome OS and Windows 10 variants.

The Lenovo ThinkPad X1 Yoga will be available starting this month from $1,449 (roughly Rs. 96,300). The laptop's Oled display model will however only hit the market in April, and its pricing has not yet been revealed. The Lenovo ThinkPad X1 Carbon can be purchased in the US starting February from $1,299 (roughly Rs. 86,300). While the Lenovo ThinkPad X1 Tablet will reach the shelves in the same month starting $899 (roughly Rs. 59,700), the Lenovo ThinkCentre X1 AIO and the Lenovo ThinkVision X1 monitor will be available to buy starting March from $1,029 (roughly Rs. 68,300) and $799 (roughly Rs. 53,000) respectively.
