BackgroundWe are currently living in an era where people do not want to deal with wired devices because they are not portable and cannot be used anywhere or everywhere. So, companies came up with a new technology where mobile phones can now be charged wirelessly just by using a wireless charging and induction technique. On one hand it is very efficient to use and has revolutionized the charger market (Lu et al., 2015). However, it is very new to even understand how it impacts the battery life of mobile phones. This is a fair assumption that in order to charge the mobiles faster, it must be putting pressure on some internal components of mobile phone. So, the underlying problem here is to research on how wireless chargers impact the battery life of mobile phones. This topic has been chosen in order to make wireless charger users aware about the impact it can have on the life of battery. Nowadays, the life of mobile phone devices has reduced to two to three years with no salvage value so user would not want anything to reduce the life further. Thus, it is important to safeguard the mobile phone battery from any such technology and therefore, there is a need to study the impact of wireless charging technology on battery life. Many researchers have done investigation on how wireless chargers work and this gives some idea about how it is treating the internal components but no one has actually tried to understand the way it is impacting the battery life. So, here is the knowledge gap where we should just not focus on the advantages of using wireless charging but also highlight the drawbacks to make people aware of the same.1. ObjectiveThe focus of this research study is to investigate the impact of wirelessly charging the mobile phone on its battery life. The sub-objectives for this research study have been identified a below:· To understand the working of wireless chargers· To understand various components of a wireless charger· To understand the impact of wireless charging on battery life of mobile phones1. Literature ReviewWireless Charging technology helps in transferring wireless power from a power source to a device such as a mobile phone through an air gap by eliminating the bunch of wires. So, it basically exchanges the power without the need to establish physical connections between the devices. Block Diagram of Wireless ChargerWireless charger works by transmitting energy from transmitter to a receiver with the help of an oscillating magnetic field as shown in above diagram. In order to support this transmission, direct current is supplied by a power source which then gets converted to high frequency alternating current (Rubenis et al. 2016). This alternating current provides energy to a copper wire coil which is embedded in the transmitter which as a result of it generates a magnetic field. Now, by bringing a second receiver coil in the range of magnetic field, an alternating current can be induced in the receiver coil. This AC signal is then transferred to the transmitter coil which further induces the magnetic field. So, the magnetic field generates current which then flows through the receiving coil. This process of energy transmission between transmitter coil and receiver coil is called magnetic coupling. The current which flows through receiving coil is converted to direct current with the help of receiver circuit. This current is useful for further powering up other devices without the need for wires (Reddy et al., 2017). Various components of a wireless charger are transmitter circuit, receiver circuit, current amplifier, wireless charger, AC to DC converter and Oscillator tank circuit. There are various advantages of using wireless mobile chargers. It eliminates the use of separate chargers and also saves the electricity cost for the users. It is also portable so phones can be charges anywhere and anytime. These chargers do not corrode when exposed to the atmosphere. It is also quite easy to plug them into a power cable (Deppong, 2013). As per a previous research article, wireless chargers provide more stable current to the devices. The wireless chargers do increase the heating problem in the mobile phones but there is no evidence that this heat directly affects the batteries of phones. However, researchers mentioned that every battery has certain life and it is going to die some day for sure. Also, due to technology advancement in mobile phone sector, now batteries are made smart enough to protect themselves even if it is being impacted by an external device. In addition to that, there are certain dos and don’ts in case of how to use a phone battery to intact or increase its life such as not deep discharging the phone battery, or not frequently charging the phone etc (Claire, 2018). 1. Hypothesis/QuestionAs the focus of this research study is to establish a connection between wireless charging technology and the battery life of mobile phones. So, the hypotheses which would be most appropriate for the given research work are represented as below:Null Hypothesis (H0): Wireless chargers do no erode the battery life of mobile phones.Alternate Hypothesis (H1): Wireless chargers do erode the battery life of mobile phones.By conducting the research on the given research problem, we will be able to select one of these two hypotheses.1. MethodologyIn the given section, we will be developing a research methodology for the given research study by selecting appropriate research and data collection method and then making use of appropriate data analysis techniques for the purpose of selecting a hypothesis and then presenting our results for wider use. The research will be conducted in both primary as well as secondary manner. In case of secondary research study, a literature review will be conducted on all the past research studies in order to go in depth of the selected research problem. The data used here will be from secondary sources like research articles, books, online article, recent news etc. In case of primary research study, we will collect primary data by conducting real life experiments on wireless chargers and batteries by using various experimental scenarios. So, the research method will be a combination of both primary and secondary methods. In order to perform experiments, charging scenarios will be prepared which will form a base for the experimental testing. These scenarios will be related to the way end users wirelessly charge their mobile phone batteries and battery’s performance thereafter. Some of the common standard scenarios are charging the phone from switched off state, charging the phone in on state and comparing it with charging the phone with wired chargers. This comparison will let us understand the performance of battery when charged from wired charges vis a vis when charged from wireless chargers. The idea here is to calculate the time that battery has taken to fully discharge after charging up to 100% in each scenario. The mobile device which will be used for the experiment purpose will be factory reset to eliminate the impact of any other factor such as storage and it also need to be updated to the latest Operating software version. Another thing to be considered here is to remove the back cover or any kind of casing from mobile phones so that no power loss can occur. The experiment will be conducted in a lab environment and investigation will be done by using required devices on scenario basis. The wireless charger will be connected to the mobile phone. The mobile phone needs to be kept untouched so that no power fluctuations can occur. It is to be ensured that mobile phone gets fully charged to its full capacity. The next scenario will be conducted once the reading for first scenario has already been recorded. There would be two parameters to check the battery life for each scenario. First would be to record the time mobile phone is taking to fully discharge from the fully charged state and the second one is to check the battery life from setting option on the mobile phone which provides a close estimate of how your mobile phone battery is performing. It is definitely not a correct estimate but gives a near about idea. The data analysis will be done using quantitative methods. The results of above experiments will be recorded in tabular form. This will allow us to perform various statistical formulas on the data such as average, regression, mode etc. Apart from that, we will also plot the results on the graph in order to see the trend and understand the relationship between mobile phone’s battery and wireless charging technology. 1. Expected outcomesThe expectation from the given research study is to investigate how wireless charges impact the battery life and whether the impact is in positive direction or in negative direction. As per the hypotheses prepared at the start of research, we are looking to see if wireless charging erodes the battery life of mobile phones or not. As per the theoretical research conducted on the given topic, wireless chargers do make mobile phones heat but this is unsure if that has anything to do with the battery performance or life. We are expecting that wireless chargers do not erode the battery life of a mobile phone on the basis that it has not been mentioned in any previous credible study and generally we have not seen it in our day to day life as well.1.

Chapter 1 Introduction
1. Background
Interestingly on our planet, the quantity of dynamic cell phones on Earth outperformed the quantity of human individuals in 2014 [1, 2]. People are generally dependent on cell phones for an assortment of purposes, including co
espondence, web based perusing, and amusement. Batteries are expected for the activity of these contraptions, and the point of these batteries is to store energy and convert it to electrical structure when required. The common technique for charging the battery is to use a link charger with one end associated with a telephone and the other to an electrical plug. The remote charging strategy for cell phones has as of late been accessible. Many major cell phone creators, including Samsung and Apple, have seen this innovation as a ground
eaking innovation in the versatile business from its commencement [2]. This innovation is projected to give various advantages, including improved comfort and the evacuation of the requirement for a very long-time port plans.
A. Wireless Charging Technology
Remote charging was first displayed in 1981 by Nikola Tesla, who showed remote power move by lighting an electric light without utilizing links [3, 2].
An electromagnetic field is utilized to send energy between two articles in remote charging [4]. An inductor, which is a circle of wound wires around a magnet, is utilized in this endeavor. An electromagnetic field (EMF) is conformed to the magnet when an electric flow goes through the inductor. This EMF may then be utilized to send a voltage or charge to a close by thing without reaching it. Different remote charging conventions have developed, with Qi and the Power Matters Alliance being the most famous (PMA). The transmission frequencies and association conventions utilized in the gadget co
espondence process, as well as power the board control, contrast among these guidelines [5].
In spite of the way that the fundamental thoughts of remote charging have been perceived for more than a really long period, researchers have neglected to find approaches to proficiently communicate immense measures of power utilizing this innovation [6]. Thus, existing remote charging advancements for cell phones have been demonstrated to be wasteful and slow in contrast with link charging [7]. In any case, in light of the fact that the portable business is quickly moving to remote charging innovation, and in light of the fact that this innovation has been forcefully invading the market lately, it is basic to examine how end clients might utilize this innovation.
B. Energy Efficiency and Wireless Charging
Remote charging failures can compound the negative ecological impacts that cell phones as of now have [10]. This is because of the way that charging requires the use of force, which is generally created from nonrenewable sources (like coal or oil) [11]. Moreover, in light of the fact that energy has financial costs, shortcomings affect service bills. Energy effectiveness improvement is a notable methodology for
inging down energy costs while diminishing ecological results [8]. The Lawrence Berkeley National Laboratory (LBNL) characterizes energy effectiveness as "the utilization of less energy to deliver a similar assistance" [9]. Energy proficient remote charging, as per this definition, alludes to the utilization of less energy to charge a cell phone under similar circumstances completely.
Different exploration looked to proficiently move a bigger amount of ability to conquer the energy shortcoming of remote charging [12]. Business options, then again, presently can't seem to be made that equivalent the energy productivity of wired-based charging. Until such choices are accessible, remote charger clients should utilize the innovation to set aside cash while at the same time diminishing natural wo
ies. Accordingly, remote charging strategies are turning out to be progressively applicable to explore. Moreover, it has previously been shown that measurably estimating the energy utilization of cell phone charging can support the ID of energy-saving choices [13, 14]. Thus, this article analyzes different charging systems to find energy-saving potential and quantitatively investigations energy-effective use of the remote charging instrument.
Chapter 2 Literature Review
This writing audit starts with a concise history of remote power transmission, trailed by a conversation of non-radiative and radiative power move studies, lastly a prologue to the foundation of the main global remote power standard (Qi) and extra norms. At last, the constraints of remote power move are inspected, as well as the fate of the innovation. During a talk in 2013, X. Wang and A. Mortazawi distinguished a needle diversion of compass as electric flow went through one wire link, showing the attractive effect of power. Andrie-Marie Ampere fostered the connection between electric flow and the resultant attractive field in 1826 with his circuital regulation. Faraday's regulation, distributed in 1831, expressed that fluctuating attractive motion could create electromagnetism in a guide. W.Brown affirmed the presence of electromagnetic radiation in 1888.
Nicola Tesla improved Hertz's remote transmitter and recorded a patent for it in 1891. Hutin and Leblanc got a patent for remote power transmission at 3k Hz in 1894. Tesla effectively touched off a light with a couple of loops around the same time. Jagdish Bose utilized an electromagnetic wave to remotely strike a chime from 75 feet away through a divider in 1895. In 1896, Marconi conveyed a radio transmission across a distance of 1.5 miles. Tesla had the option to communicate power remotely across a distance of 48 kilometers. An award was given in 1904 for an effective work to run a 0.1 pull (75W) air shipmotor utilizing energy imparted through space a good way off of somewhere around 100 feet. In Los Alamos National Laboratory, the primary inactive framework Radio Frequency Identification (RFID) beneficiaries were fueled by electrodynamics enlistment from a couple of feet away in 1973.
Teacher Marin Soljacic's physical science research bunch at the Massachusetts Institute of Technology (MIT) introduced a coupled attractive reve
eration power move framework and his outcome in remotely fueling a 60W light with 40% productivity at a 2m distance utilizing two 60 cm-width curls in 2007, named "Witricity" [14]. Intel as of late repeated the MIT gathering's work by remotely driving a light at 75% proficiency across a more limited distance [15]. Dr. Edge, a teacher of Nuclear and Quantum Engineering at KAIST University, and his associates utilized inductive power move to ship energy across a distance of 3-5m in 2015, with effectiveness of 29%, 16%, and 8% for 3m, 4m, and 5m, individually [16]. They utilized signals at a recu
ence of 20 kHz. Reference [17] sums up remote power move studies from 2001 to 2013, refe
ing to around 50 articles. Fu and Imura, as per [17], are the most useful creators. The really four countries associated with this area are the United States, South Korea, China, and Japan.
History of wireless charging
A concise history of remote charging innovations as well as significant accomplishments. The innovator of rotating flow power, Nikola Tesla, was quick to em
ace a remote charging test. In 1899, he impacted the world forever by sending 108 volts of high-recu
ence electric power more than a 25-mile distance to light 200 lights and drive an electric engine. Tesla constructed the Wardenclyffe Tower in 1901 to circulate electrical energy globally without the need of wires through the ionosphere. The thought has not been
oadly evolved and promoted in light of the fact that to innovative constraints (e.g., unfortunate framework proficiency). Afterward, during the 1920s and 1930s, magnetrons were formed to change over energy into microwaves, considering significant distance remote power move. Nonetheless, until 1964, when W. C. Brown found a method for changing over microwaves back to power utilizing a rectenna, it was basically impossible to do as such. Brown showed the plausibility of microwave power transmission by driving a model helicopter, which started a rush of microwave-controlled flying exploration in Japan and Canada during the 1980s and 1990s [1]. Various consortiums, for example, the Wireless Power Consortium [2], the Power Matters Alliance (, and the Alliance for Wireless Power [3], have as of late been framed to foster overall remote charging norms. Numerous products available now consent to the measures.
