Powering Up The Cloud
Battery life has been the biggest problem for almost all smartphone users, but manufacturers have rarely been seen trying to accommodate the user’s needs in this department. A high-end smartphone these days won’t last you a day if your performance is moderate to heavy. This need of smartphone users for more battery power has allowed the charge cases and external battery manufacturing companies to flourish over the years.
Lithium is considered the prime metal to be used for batteries because it offers the most potential since it is lightweight and has the highest energy density. Simply put, with lithium you get more power per volume and weight.
Nowadays, researchers are constantly looking for ways to decrease the workload on a smartphone in order to increase its battery life. It’s a new way to tackle the problem of a small smartphone battery. We can use Amazon cloud as an example; its cloud can store personal data and perform computations on that data. So the main question we can ask ourselves is, can offloading mobile applications into the cloud, save us energy? The answer is a complex one, especially since mobile computing uses limited energy and because of the data transfer speed of the wireless connection.
Everything boils down to efficiency. If a mobile application uses too much energy in the cloud, running it is not feasible. Increased energy consumption means smaller battery life, and since battery life is of key importance to smartphone users, this is not efficient. To make computation offloading more attractive, applications would need to be developed in such a way that they would be more efficient running within the cloud network, rather than on the mobile device itself.
There are obvious concerns to the privacy and security of such data transfers, not to mention that these mobile applications can only be used when we’re connected to a high-speed network; preferably 4G/LTE or a Wi-Fi connection. There are areas where there is no coverage of either of these two networks; so these applications would not be available to the user at that time. If the data transfer speed of these networks decreases, the smartphone would ultimately use more power to facilitate the transfer of data and the original purpose of offloading these applications would become moot since the power consumption would ultimately increase.
We can ultimately conclude that even though there are many ways to save battery life on a mobile device, many of these ways come built-in from the manufacturer themselves. Cloud computing can potentially save a lot of energy for mobile users and erase the need for high-tech batteries. Not all applications would be able to save energy when migrated to the cloud but rather, they would do the opposite. In the end, the quality of computation would depend upon the privacy, security and the reliability of the data connection because if the connection contained all these qualities, it would lead to the mobile offloading becoming common and a good share of the mobile battery being saved.
