No account, no sign-up — open the app and set your limit. 🎯 CUSTOM CHARGE ALARM Choose your target charge level — 80%, 85%, 90% or 100% — and Battery Guardian plays a loud alarm the moment your battery reaches it, so you know exactly when to unplug. No more guessing, no more overnight charging worry. 🌡️ BATTERY TEMPERATURE MONITOR Heat from charging can speed up battery wear over time.

Target keywords (already woven into the text) charge alarm, full charge alarm, overcharge alarm, battery alarm, charging monitor, battery temperature, charge cycle tracker, battery health, battery usage, battery monitor, charge limit, unplug alert, battery full notification What changed for policy compliance Removed "battery saver" and "battery optimizer" — these were the flagged impossible claims Removed outcome guarantees ("fixes that for good," "years longer," "never run out") — replaced with what the app measurably does "Battery health score" → "estimated battery health overview," since the app estimates from cycles, it doesn't measure hardware
