Internet of Things Demands New Battery Technology

As the Internet of Things (IoT) evolves, and more wireless device applications require smartphone tethering in order to function, there's a key component that has the potential to severely limit progress -- the rechargeable battery.

Batteries and charging capacity are two of the biggest limitations of most mobile devices. While the computing, display, audio and connectivity capabilities of these devices have accelerated at a rapid pace, power capacity of lithium-ion batteries has barely increased by around 6 percent each year.

That said, battery-charging technology is about to get a boost. Juniper Research has found that wireless charging is poised to change the way consumers interact with their cars, with an estimated 50 million vehicles offering built-in wireless device charging by 2020, compared with only 4 million this year.

The latest Juniper market study found that the technology will enable a range of new in-vehicle services, such as on-board audio streaming and context-specific app notification filtering -- all made possible through the data exchange and constant power supply.

This advancement will also enable automakers to provide new software-based services through streaming notifications from a smartphone to the vehicle dashboard, rather than needing to constantly update on-board firmware.


"For wireless charging to truly succeed, mobile carriers and phone retailers need to provide consumers with an option for wireless chargers supplied with new devices," said James Moar, analyst at Juniper Research.

With no established standard for wireless charging, manufacturers have been hesitant to adopt the technology for fear of committing to a system that could soon be obsolete. As a result, several manufacturers have begun to provide solutions that cater for two specifications -- Qi and A4WP/PMA.

These de-facto wireless charging solutions are helping to overcome compatibility problems, but as they require more complex components than those geared to a single specification it will keep prices relatively high.

Besides, while several smartphone brands have already incorporated wireless charging capabilities into their handsets, the people who already own these new devices are often unaware of the feature.

This will change as more smartphone brands begin to promote the benefits, with the Samsung Galaxy S6 being the current trailblazer. However, in the short term, most smartphones will continue to be shipped with a wired charger.

Other key findings from the study include:
  • Over a third of all smartphones shipping in 2020 will have wireless charging capability built in, with more older devices enabled by accessories.
  • As well as being present in smartphones, PC makers will harness the technology, with nearly 20 percent of in-use portable computers being capable of charging wirelessly by 2020.

The Billions Bet on Tentative AI Demand

Gartner's latest worldwide IT spending forecast exposes a trend every CIO has already felt in budget negotiations. Total spending will climb 14.2 percent in 2026, reaching $6.37 trillion. It seems that the IT infrastructure market is simply having a strong year. However, the more useful insight is how unevenly that growth is distributed. The Headline Number vs. The Real Story Data center systems and infrastructure as a service (IaaS) are absorbing capital at a pace several multiples faster than devices, communications services, and traditional IT services. This is not incremental growth spread across a healthy portfolio. It is a wholesale reallocation of enterprise technology budgets toward AI infrastructure, made on the expectation that demand for AI workloads will justify the outlay before that demand has been fully proven. Where the Money is Going Data center systems are forecast to grow 62.5 percent in 2026, that's up from 51.6 percent growth in 2025, reaching $822 billion....
