Open Source Go Mobile Apps for Android

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. The UI supports zooming into problem windows, filtering by UID or tag, and comparing multiple runs to verify improvements. It also surfaces metrics summaries and highlights known anti-patterns so performance teams can focus on the highest-impact fixes. Battery Historian has become a staple in diagnosing real-world battery regressions during app development and system bring-up.

halogenOS test builds (release builds are just a leftover) The test builds and modules are supposed to be only used by our testers. But if you are not a tester, and use these builds anyways, don't expect support if you get problems. You can report the bugs, but you have to be experienced enough to know how to revert back to a working state and how to report bugs and provide logs.
