Know your battery, protect its lifespan.
Battery Health Monitor gives you a clear, technical view of your device's battery: temperature, voltage, charging speed, and estimated wear over time, presented in plain language with the detail power users want underneath.
Set a charge-limit alarm to reduce trickle-charging past 80–90%, track discharge patterns, and get an early signal if your battery's health starts declining faster than expected.
