Methodology
This chapter includes the framework of the subject being studied. It includes Research
Design, Subject of the Study, Materials and Instruments, and Data Gathering Procedures.
Research Design
The researchers used quantitative research design that shows the numerical data of the
topic and used statistical methods to formulate hypotheses. The researchers utilized an
experimental approach to present the data properly.
Subject of the Study
The researchers used different phone brands with different battery capacities to
determine how online mobile gaming consumes power with respect to their battery
percentage. This study was held at Batangas State University Main Campus II. This study
made use of Second Year Electrical Engineering students of Batangas State University.
Materials and Instruments
The study uses four (4) different phone brands with different battery capacity and
timer.
Data Gathering Procedures
1. Measure the battery percentage of the phones that are not being used with an hour
of time duration.
2. Measure the battery percentage of the phones that are being used, non-stop online
mobile gaming, with an hour of time duration.
