ChargeGuard

ChargeGuard is a mobile app (Android first, iOS limited) that finds what’s actually wrecking your phone battery and charging health—without vague “tips.” It monitors charging sessions, temperature spikes, fast-charge behavior, and app wake-lock patterns, then flags repeat offenders with clear actions: change a setting, uninstall an app, replace a cable/brick, or adjust charging habits. On Android it can run deeper diagnostics (accessibility + usage stats) and offer automation suggestions; on iOS it focuses on user-guided checks and charger/cable verification via a small companion web flow. The app also keeps a “battery health diary” so users can see whether changes helped over 7–14 days. Monetization is straightforward: freemium with a paid plan for advanced insights, historical trends, and family device monitoring. This is not magic—some drains can’t be fixed—but it will catch the common, expensive ones.
