How to Create Sustainable Mobile Apps
summary
Practical techniques: replace constant GPS polling with geofencing and reduced location precision, batch and defer network work using deferrable URL sessions, cache/compress media, and avoid needless background wakeups and timers; one app’s tracking precision/frequency tweaks reduced battery impact by two times. Measure with GHG protocol for totals or the Software Carbon Intensity (SCI) spec for per-user rates; use Xcode gauges and Instruments to find hotspots. Note platform choices matter: Swift ~40% more energy efficient than Dart, ~60% than JavaScript, and dark mode can yield ≈40% power reduction on modern displays.
