Smartphones have become an indispensable part of our everyday life. Smartphones appeared in the market almost two decades ago. Soon they captured the market as an alternative to mobile phones which offered only primary functions that enabled only two way communication by either text or call. Smartphones possess much more advanced and smarter capabilities than mobile phones, with additional and essential functions like multimedia entertainment, web browsing, games etc. – almost like a mini-computer which is small enough to fit into your pocket. The new Smartphones of today have other extended capabilities like in-built high-quality camera lenses, video-streaming, connectivity that enables millions to stay connected while on the go and also mobile apps that aid the productivity.
What is the expected development of smartphones in the near future, is probably very hard to predict with accuracy. The phone companies are notoriously secretive these days. 2014 witnessed the year of emerging digitized things such as cloud services, interactive apps, online selling of products and paying. Once the trend was smaller phones, but in 2015 they will be thinner, larger, lighter, and much more powerful. The emerging technological trends of smartphones that are expected to take off big in 2015 are listed below:
Smartphone with ultra HD or 4K display
By the end of 2015, High resolution 4K phones with crisper and sharper display may hit the market. The screens will be bigger with 4K, also known as ultra HD. 4K resolution is the common name for ultra-high-definition on the order of 4,000 pixels.
Some of the higher-spec phones available now boast 2K resolution. It is more likely that some manufacturers will have a stab at being the first to make the high resolution 4K phone by the end of 2015. With the sharper and crisper display, watching TV and films will become common as we are watching them on our tablets and laptops with little to no loss in the quality.
Some of the smartphone manufacturers are of the opinion that 4K display on smartphone would result in major compromise in the battery life. 4K needs a lot of power and smartphone with 4K display may give you half day of battery life while 2K display can give a battery life of a day or even more. 4K has four times the pixels of Full HD, so the power consumption maybe 4 or 8 times as much as the Full HD. So naturally the smartphone has to compromise on the battery life.
4K looks really impressive on the large screens but it is going to be difficult to tell the difference between 4K and 2K on smaller smartphone display of five to six inches.
Kiss Connectivity for smartphonesKeyssa is a US-based company has recently hinted surface of its technology called “kiss-connectivity” technology. This new technology promises speedy data transfer between the devices while eliminating the need of I/O ports and need of wires. The technology seems to be amazingly impressive. A connector that is of the size of a coffee bean can be integrated into a number of devices to enable the transfer of data between devices like smartphone, tablets and notebooks. The connector uses extremely high-frequency- short range radio band that zero drain the battery.
The idea behind this technology is eliminating the unpleasant connectors on the pleasant devices. The image of high-end smartphone with no I/O ports littered on its perimeter is admirable. With no need of I/O ports, wires and cords the transferring of data between the devices becomes easy and it eliminates the need to look out for the connectors to connect the devices.
Wireless charging for smartphones
2015 will be a landmark year for the growth of deployment of wireless charging.This concept is not a new feature for smartphones. It is already available in number of Nexus smartphones and Nokia has integrated the technology into its range of Windows phones. Wireless charging is a fantastic system with not worrying about unplugging cables or remembering about the USB connection. You can simply pick up the handset and go away with confidence of having a handset that is charged as it can be.
The smartphones can be charged by simply placing them on a wireless charging accessory. With a single connection to the outlet, the area can be kept free of tangled power cords. The technology works by taking advantage of the principal of magnetic induction, and allows the power transfer from a charging mat or pad to a smartphone battery.
Many smartphone users will be wondering whether their NFC chip (Near Field Communication chip) can be used to harvest power from an external source or perhaps an ambient electromagnetic source like Wifi. To achieve maximum efficiency the system should be optimized for use at a particular distance of separation, phase, angle of incidence and frequency such that it is in a resonant condition.
For the time being, magnetic inductive charging technologies-spearheaded by the Qi consortium have taken the stage. Other wireless future charging technologies relying on solar power or ultrasound are being developed.
