-# battery_health
+# MEIZU Battery Healthy
 
-A new Flutter project.
+> 专机专配 · 仅针对魅族独家开发
 
-## Getting Started
+一个简洁的手机电池健康度监测工具<br>
+通过读取 BMS 日志（`/storage/emulated/0/mbattery_charger/`）直接获取电池真实数据<br>
+不依赖系统 API 估算。
 
-This project is a starting point for a Flutter application.
+---
 
-A few resources to get you started if this is your first Flutter project:
+## 功能
 
-- [Lab: Write your first Flutter app](https://docs.flutter.dev/get-started/codelab)
-- [Cookbook: Useful Flutter samples](https://docs.flutter.dev/cookbook)
+- 读取 BMS 日志，解析 `learned_cap`、`cycle`、`tbat`、`vbat` 等关键字段
+- 显示电池健康度（当前容量 / 设计容量）
+- 显示循环次数、电压、温度（含当日极值）
+- 近 15 天容量百分比趋势柱状图
+- 实时充电状态识别（有线 / 无线、PPS / SDP / EPP）
+- 充电功率、电压、电流实时显示
+- 充电详情页（协议 / 功率 / 电压 / 电流 / 档位）
 
-For help getting started with Flutter development, view the
-[online documentation](https://docs.flutter.dev/), which offers tutorials,
-samples, guidance on mobile development, and a full API reference.
