Battery Stats Reset的4大原因：
一、读电池文件异常执行reset[BatteryStatsImpl.RESET_REASON_CORRUPT_FILE]
超过200个持锁；
超过200个syn或job；
超过1000个sensor；
超过1000个processes；
超过1000个应用；
超过1000个alarm
超过10000个service
二、命令行执行reset[BatteryStatsImpl.RESET_REASON_ADB_COMMAND]
adb dumpsys batterystats --reset
三、充电执行reset[BatteryStatsImpl.RESET_REASON_FULL_CHARGE]
充满电状态
电量百分比90%以上，
电量百分比从20%以下到80%以上
充电期间累计总充电量百分比>200%
四、开机检测到power buckets改变执行reset[BatteryStatsImpl.RESET_REASON_MEASURED_ENERGY_BUCKETS_CHANGE]
每次开机检测当前机型所支持的POWER_BUCKET_的类别和数量是否发生改变，若和上次开机不同，则表示可能存在兼容性差异(MeasuredEnergyStatsConfig.isCompatible(config))，需要reset 可能场景举例：换电池或刷其他power_profile的版本

@IntDef(prefix = {"POWER_BUCKET_"}, value = {
POWER_BUCKET_UNKNOWN,

POWER_BUCKET_CPU,
POWER_BUCKET_WIFI,
POWER_BUCKET_BLUETOOTH,

MeasuredEnergyStats.POWER_BUCKET_MOBILE_RADIO,// Modem 电量消耗桶
MeasuredEnergyStats.POWER_BUCKET_WIFI,// WIFI 电量消耗桶
MeasuredEnergyStats.POWER_BUCKET_BLUETOOTH,// 蓝牙 电量消耗桶
};
本次开机检测到与上一次开机CPU、Modem、WIFI、蓝牙的电量消耗桶发生变化了，之前的数据可能不可靠，需要进行重置
