※ 引述《scottnet (Scott)》之銘言:
: <圖1>現在又出現CPU單核心佔用100%了!!!

: <圖2>不過Battery Mix看不出異常: (MoPTT單純是廣告很耗電)

: <圖3>GSam Battery Monitor 顯示是Kernel的問題:

: <圖4>"核心(Android系統)" 點進去,裡面大概包含30種程序吧:

: <圖5>剛發現裡面有一拖拉庫的"kworker",不知道是啥小:

: 現在看起來就是核心Kernel在耗電了!
: 我現在打算暫時不重開機,繼續維持這個狀態。請問:
: 1. 是否有其他工具可以抓出Kernel中各子程序的CPU usage ?
: 2. 是否能強制kill該程序 ?
: 重申一下我的系統:
: Nexus 4
: 原廠 Android 5.0 LRX21T
: 幾天前剛全機wipe重新安裝
: 有root
: 感謝!!!
其實我對Lollipop的耗電量也滿好奇的。
因為第一天剛刷完,續航力真的很可悲,
之後就時好時壞,但也不到不勘用的程度。
XDA也有人發現到耗電的問題,不過測試的機器是 Nexus 5。

以下是測試結論:
1. Overall Battery Consumption of Lollipop is significantly higher than that of
KitKat.
整體來說,Lollipop比Kitkat還耗電
2. The default Battery Stats are inaccurate in Lollipop. It's accurate in KitKat.
Lollipop 預設的電量狀態是不準的,但是在kitkat是準的。
3. WiFi shows as 'Always ON' in Lollipop's default battery stats but it is
actually OFF and consumes no extra power. (Thanks to GSAM).
當Wifi關閉的時候,在Lollipop的電量狀態中卻是顯示一直是開啟的狀態,但不會耗更
多的電量。
4. No 3rd Party Applications are causing drain in Lollipop. Neither is WiFi
(Scanning always available or Network Notification or Whatever....)
第三方的應用程式,並不會導致Lollipop噴電。
5. Cast Services in Lollipop are not draining battery.
Cast services 並不會使Lollipop 噴電。
6. Project Volta & App Optimizations - Google Apps are expected to be optimized
to consume less power. But it seems exactly the opposite.
Project Volta & App optimizations 理論上會幫助省電,但實際上卻相反。
6. Android System, Kernel (Android OS) & Google Play Services in Lollipop 5.0
consume 2.5 times more power to run than in KitKat 4.4.4 (6.1% vs 15.3%)
Android System, Kernel (Android OS) & Google Play Services 這兩個App在 Lollipop
的耗電量是Kitkat的2.5倍。
7. Extremely disappointed with Google. Lollipop 5.0 LRX21O has rendered the
Nexus 5 unusable.
對Google 非常失忘....
8. The Rest is for you to judge my friends.
剩下的就是你們的判斷了~

簡單翻一下,有錯請指教。
