Hi everyone! I'm interested in doing an informal study on the battery life of the new iPhone 5S. Basically, I want to track how well percentage of battery life correlate with usage and standby time. If you would like to participate in this study, please fully charge your iPhone 5S and use it as normal would. At the end of the day or before you charge it again, take a screenshot of the usage screen and post it here along with the date and any comments you may have from that charging period. Of course, everyone's usage of their phones vary. By getting as many data points as possible, this should hopefully reduce any impacts outliers may have. Please let me know if you have any questions, comments or concerns about this study.
