Rugged Pro Battery Saver

Rugged Pro Battery Saver is a battery-first watch face engineered for maximum efficiency. It is built around a simple idea: the lowest power watch face is the one that avoids sensors, avoids heavy assets, and redraws as little as possible. This watch face intentionally does not use fitness metrics (steps, heart rate, Body Battery, stress, touch, GPS). Instead, every metric is derived only from system battery and time, so you get meaningful battery insights with the smallest possible energy impact. Battery Insights (what you see on screen) * Battery % Native device battery percentage. * Use / Charge Trend Shows how fast the battery is changing right now (drain or charge rate). Computed from throttled battery samples (no continuous polling). * Since Charge Time elapsed since you unplugged the charger. Updated with aggressive throttling and instant refresh on unplug events. * Custom Top Field (battery-only) — choose one * Score: battery efficiency grade (A–E) based on the current drain rate * Left: estimated time remaining at the current drain rate * Charging: current charging session duration (or last session duration after unplug) Why it’s so efficient * No sensors and no sensor subscriptions (zero sensor wakeups) * No PNG/SVG assets, no animations, no unnecessary effects * Throttled calculations (battery sampling and charging checks are rate-limited) * Dirty-flag partial redraws (only changed areas are redrawn) * Cached strings, fonts, and static graphics (minimal allocations during runtime) Rugged Pro Battery Saver is designed for users who want the most autonomy possible and prefer battery intelligence over extra metrics.
