...Although there are already a lot of writings on the internet on the topic, a great number of possible scenarios still have to be thought of, like unsuccessful compressions, too small pictures (eg. for profile pictures) or too bad image quality. Naturally, the first idea was to see how WeChat, the app giant manages this task in action. To gather data, 100 images with different resolutions were sent through WeChat Moments, then the compressed images were compared with the original ones. Luban's foundation is the result of this analysis on WeChat's compression method. Because the process was analyzed backward, Luban's efficacy is not yet exactly the same as that of WeChat, but the results are already very close to what WeChat Moments' image compression produces.

Battery Historian is a visualization and analysis tool for Android power usage that turns raw bugreport and batterystats data into actionable timelines. Developers upload a bugreport and get interactive graphs that show wakelocks, jobs, alarms, network activity, CPU states, screen usage, and app-level events. By correlating these signals, it helps identify abusive wakeups, runaway services, or networking patterns that drain battery.
