Hello, I bought a like new iPhone X on Sept. 18th and the Maximum Capacity at the time was 100%. Today, I checked it and it was at 98%. My avg. screen on time is 5hrs 51mins a day and avg. screen off is 1hr 3mins. It's quite hard to believe my screen is on almost 6 hours a day. I work full time and while I do check it quite often I have a hard time seeing how it adds up to 6 hours a day. Any thoughts? Is my avg. screen on time in the 99th percentile or something? Is that why my battery capacity dropped so quickly?
