20171010聯通流量懸浮球導致的瀏覽器功耗偏大

功耗現象

留意下流量球

分析

現象：聯通流量懸浮球會在某些網頁纔會出現。
對比發現：
1.不帶聯通流量懸浮球的界面CPU開核數1核，且電量540mA
2.帶聯通流量懸浮球的界面CPU開核數3核，且電量993mA

即屏蔽聯通流量懸浮球來解決流量網頁功耗大現象

優化前後測試電流數據如下

功耗原因

聯通卡在原生瀏覽器中會出現流量球，並不斷刷新流量數據，導致CPU被強制佔用到3核最高頻率運行，導致電流過大，一下會手機就嚴重發燙，且快速掉電。

解決方案

瀏覽器過濾掉聯通懸浮球的uri及其執行腳本
http://120.80.57.123/www/default/base.js?v2.1

package com.android.browser.homepages;

public class HomeProvider extends ContentProvider {

    public static WebResourceResponse shouldInterceptRequest(Context context,
            String url) {
        //Log.e(TAG, "shouldInterceptRequest: url=" + url);
        try {
            //#ifdef LAVA_EDIT
            //suhuazhi.2017-01-11,remove unicom float ball
            if (url.startsWith("http://120.80.57.123/www/default")) {
                Uri uri = Uri.parse("content://com.android.browser.home/");
                InputStream ins = context.getContentResolver().openInputStream(uri);
                return new WebResourceResponse("text/html", "utf-8", ins);
            }
            // #endif

代碼進一步優化
            //#ifdef LAVA_EDIT
            //suhuazhi.2017-01-11,remove unicom float ball
            if (url.startsWith("http://120.80.57.123/www/default")) {
                return new WebResourceResponse("text/html", "utf-8", null);
            }
            // #endif

測試現象如下：body不執行，懸浮球消失，功耗恢復正常

body不執行

懸浮球消失

結語

以前的功耗分析筆記，以後慢慢往CSDN搬，作爲給自己的筆記參考，方便查看，也督促自己每天學習，人容易生鏽。
