通过JS代码实现获取安卓设备实时电量，也可以显示是否在充电，挺有意思的。

我测试只有安卓可以正常显示苹果好像不行。

HTML

<div class="zib-widget">

        <div class="text-center">
            <h3>电池</h3>

            <div class="batteryShape">

                <div class="level">

                    <div class="percentage" style="width: 100%;">

                    </div>
                </div>
            </div>

            <div class="percent">100%</div>

            <p class="batteryTime">正在充电</p>

        </div>
    </div>

CSS

.batteryShape{
    position: relative;
    width: 140px;
    height: 65px;
    margin: auto;
    border: 3px solid #333;
    border-radius: 10px;
}
.batteryShape::before{
    content: '';

    top: 50%;
    right: -12px;
