## Description

The most detailed battery info app — see your battery health the moment you install it.<br><br>■ Battery Health (SOH)<br>Estimates your battery&#39;s real capacity vs. design capacity by integrating measured mAh across charge sessions. Confidence grades (high/medium/low) and a trend chart show you the evidence, not just a number.<br><br>■ Charger Tester<br>Every charge session records the real delivered power (W) and automatically builds a profile for each charger and cable you use.<br>• Charger performance ranking<br>• Verdicts: Normal / Below expected (bad cable or counterfeit charger) / Slow<br>• Detects cables getting slower over time<br><br>■ Real-time Info<br>Voltage, current, temperature, power (W) and charging state — live. Home screen widget, Quick Settings tile and a live status-bar notification included.<br><br>■ Charging &amp; Discharging Science<br>• Time-to-full estimate and per-session charged mAh<br>• Screen-on/off drain rates, deep sleep efficiency, remaining time estimate<br>• Target charge alarm (e.g. 80%) and high-temperature warning<br><br>■ Stats &amp; History<br>Real-time / daily / weekly charts, 24-hour daily activity timeline, charge history, CSV export and JSON backup &amp; restore.<br><br>■ Privacy<br>All measurements stay on your device. No account, no sign-up.<br><br>Note: some values depend on sensors provided by your device manufacturer; unsupported items are transparently marked as &quot;estimated&quot; or &quot;not supported&quot;. A non-root app cannot physically stop charging — the target alarm notifies you instead.
