The Power Consumption

The agency usance for sending (or receiving) a single message in a mobile phone Abstract We measure overall SMS, Whatapps and Wechat for the originator consumption of a single message. These results are validated by overall top executive measurements of two another(prenominal) devices the electric battery affect and outpouring Detective. We discuss the significance of the forcefulness drawn by the various continuance and time of texting messages, and identify the most promising areas to focus on for further improvements of power management. We also analyze the energy impact of dynamic voltage and frequency scaling of the devices application processor.Introduction In recent years, people have a mobile phone in their hands all the day. At the same time, device functionality is increasing rapidly. In the number of applications, texting messages occupied an important part. Hence, optimal management of power consumption of devices such as SMS, WhatsApp and WeChat is critical. In this paper we attempt to answer how much of the systems energy is consumed by sending (or receiving) a single message of the system and under what circumstances. And we will manipulation IPhone5 as the experimental product.Furthermore, we validate the results with computing manually and the additional mobile device Battery reinstate, Battery Detective. Material Experimental product IPhone5 (IOS6. 1. 2) Timer Testing Applications Messages, WhatsApp, WeChat Measuring Application Battery Doctor and Battery Detective Formula 1)The time of sending each message=The time of the purpose of 1% power/ morsel of messages. 2) Average electricity consumption of each message ( with the Wifi usage)= 1% power of Iphone 5/ Number of messages. ) Average electricity consumption of each message ( without the Wifi usage) =(1% power of Iphone 5/ Number of messages) (The time of sending each message x The power consumption rate of wifi function). methodology Device under test Experimental setup W hen an iPhone is not actively being handlingd (the cover version is off), the biggest power drain are the various radios wireless local area network, 3G and Bluetooth. So first tip is to turn off either renovation you dont need. Settings are useful in doing so with one tap. There is close to information you need to calculate before we collect the entropy.Therefore, after you turn off all the service that you do not use, you have to turn on the Battery Doctor and check out the battery usage of your phone and calculate how much usage if 1%power. In the case of IPhone 5, the battery usage is 1430, therefore IPhone 5 1% power= 1430/100= 14. 30 mAh. Also, you can use the Battery Doctor to check out how long you still can use on that percentage of battery. Then, according to the Doctor Battery, when IPhone 5 in 41% power, it can use 8hrs 15mins without the WiFi function. If use with the WiFi function, it can use 7hrs 13mins.Therefore, you can calculate that The power of IPhone 5 in 41% 14. 3mAh x 41 = 586. 3mAh The power consumption rate of IPhone 5 without the WiFi function 586. 3 mAh/(60 x 8 +15) x 60 = 0. 0197 mAh s-1 The power consumption rate of IPhone 5 without the WiFi function 586. 3 mAh/(60 x7 +13) x 60 = 0. 0226 mAh s-1 The power consumption rate of WiFi function 0. 0226 0. 0197 = 0. 0029 mAh s-1 Then, you get all the basic information which you need, and you can turn off the Battery Doctor, and fail to collect the data. Then, you need to let your phone natural reduce 1% power. after(prenominal) it you can use the timekeeper to count time and type your message and send it out. After you use 1% of power, you can hinder the timer and count how many messages did u sent and record it. Then, you need to repeat to collect those data several times. However, you also need to do it in different power percentage, to collect more data. After u collect the data of time and number of messages sending, you can use those formula to calculate the information. co mputer software Excel, Word, Battery Doctor, Battery Detective Results We had collected the data from 3 different power level, high power (80%), general power (20-80%), and lower power (
