This eliminates display brightness as a variable, ensuring that one phone isn't unfairly penalized due to a brighter screen setting.

Our testing included a mix of common daily tasks. We started with browsing the web using Safari, scrolling through various websites with mixed media content for a total of one hour. Then, we streamed video content from YouTube at 1080p resolution for another hour. This tests the phone's ability to handle multimedia playback, which is a common activity for most users. Social media usage was also included, with an hour spent scrolling through Instagram and Facebook, interacting with posts, and watching videos. This simulates the typical social media consumption habits of many users.

Gaming is a notorious battery drainer, so we dedicated an hour to playing a graphically intensive game – in this case, Call of Duty: Mobile. This provides insight into how each phone handles sustained, high-performance tasks. Finally, we left both phones on standby mode for eight hours overnight to measure overnight battery drain. This helps us understand how well each device manages background processes and idle power consumption.

Throughout the tests, we closely monitored battery percentage using a calibrated battery monitoring app. We recorded the battery level at the start and end of each task, allowing us to calculate the battery drain per activity. By averaging the results from multiple runs of each test, we aimed to minimize the impact of any anomalies and ensure the accuracy of our findings. This rigorous approach gives us a clear picture of how each phone performs under consistent and realistic usage conditions.
