OpenHarmony 5.0状态栏息屏状态下充电然后亮屏会出现电量跳变情况

1.背景

在OpenHarmony 5.0中在息屏状态下充电一段时间突然亮屏，状态栏的电量会出现跳变情况

2.解决方案

是由于有一个策略导致在息屏状态下会关闭对底层的电量监听，然后在亮屏状态下在打开此监听，所以导致在亮屏状态下会有电池电量跳变情况

解决方案patch如下：

+    // this.mManager.applyPolicy([POLICY.SCREEN_POLICY]);}unInitBatteryModel() {

上述是对锁屏的电量跳变问题解决方案，如果想更进一步优化，在极端情况下亮屏立即打开锁屏状态栏也不会跳变的话则需要在systemui的状态栏中进行优化，如下：
