Reproduce a controlled idle and active period
Compare a known user journey and a known idle interval on the same device conditions. Screen brightness, radio conditions and other apps can dominate a casual battery comparison.
Use the battery guidance and appropriate system diagnostics for the device version. Record the workload and duration before comparing builds.
Inventory recurring work
| Source | Review question |
|---|---|
| Wake lock | Is acquisition bounded and release reliable? |
| Network retry | Is backoff bounded and connectivity-aware? |
| Location | Is frequency/accuracy proportional to the feature? |
| Background worker | Does it use the supported scheduling model? |
| Timer or polling loop | Can an event-driven or batched approach replace it? |
The background-work guide helps choose APIs appropriate to persistent, deferred or user-visible work.
Examine failure paths
A successful request may release resources correctly while a timeout leaves a wake lock or retry loop active. Test offline operation, cancellation, process restart and server errors.
Avoid repeatedly waking the device to discover that a task cannot proceed because the network is unavailable.
Optimize without breaking delivery guarantees
Batch compatible work and use appropriate constraints, but keep urgent user-facing operations within their documented execution model. Delaying everything indiscriminately can break reminders, uploads or communication features.
Validate with field signals
After a controlled local improvement, monitor affected versions and devices through the relevant quality metrics. A short bench test may miss long idle-period behavior.
APKLint's Performance and Vitals checkers are review aids, not power meters. The useful evidence is reduced unnecessary work or wake-lock duration under a defined scenario, followed by field confirmation—not a generic claim that a smaller APK always uses less battery.
