* Wakelock Detector currently does not work with KitKat. Google made some changes of accessing to battery stats. We are working hard on finding a solution. We ask you to be patient, and will let you know as soon as we fix it *
Ever wondered why your smartphone screen doesnt turn off automatically when it should have, the screen wakes up all of a sudden or you find your phone battery drained even when you exited apps and turned off the screen? This might be due to wakelock holding apps. ”Wakelock Detector” helps you to detect battery draining apps in your Android phone by checking wakelock usage history. Now you can easily find out what keep your phone awake and drain your battery when it is idle!
“Wakelock” is a mechanism of power management service in Android OS, which can be used to keep CPU awake (Partial wakelock) and keep the screen on(Full wakelock). Applications which use wakelock privilege improperly leads to situations where the CPU or phone screen stays active without user's knowledge and thus causing dramatic battery drain.
“Wakelock Detector” shows wakelock usage statistics for all applications, which ever held wakelock since boot. By default it displays CPU wakelocks sorting by the longest usage time. Further, you can choose Screen wakelock type to see screen related wakelocks. For instance, if your screen is keeping on even after screen timeout or your screen turns on randomly by itself, then you can choose Screen wakelock type on the top (Brightness icon) to see which apps are using screen wakelock. Furthermore, if you are interested in currently running applications then you can change sorting type to "Active" which shows active running applications on the top. For further details please refer to FAQ inside Settings.
Main features:
# shows both CPU wakelock (Partial wakelock) and (Full wakelock) ;
# merges wakelocks of corresponding app into one expandable view for better user experience;
# currently active running applications are shown in red color;
# allows easy sorting options by Running state , Wakelock time and Alphabetical order;
How to use:
#1 Charge your phone above 90% and unplug cable (or just reboot the phone)
#2 Give it a time (1-2 hours) to accumulate some wakelock usage statistics
#3 Open “Wakelock Detector”
#4 Check the apps on the top, if they show very long wakelock usage time then you found the cause of your battery drain!
#Notice
We are working on improving the performance of the “Wakelock Detector” by adding new features regarding wakelock issues users usually face. We are trying to follow up all your comments. And we know that the application is not ideal yet. We would appreciate if you send us email before giving negative comments in the Play Store. Your feedbacks are always welcome!
* MIUI users - Make sure that battery service is turned on.

"Wakelock Detector"
是否有想過為何您的智能手機在它應該自動關閉屏幕的時候卻一直亮著，屏幕突然亮起或者雖然您已經退出應用程序並關閉屏幕但您的手機電量還是用得飛快？這些可能是持有喚醒鎖的應用程序造成的。 “Wakelock Detector”通過檢測喚醒鎖使用歷史來幫助您找到Android設備上消耗電池的應用程序。現在使用該應用，您就可以很容易地找出哪些應用程序在消耗您的電池！
“Wakelock”是Android系統上的電源管理機制，其它應用程序可以用它來保持CPU喚醒（局部喚醒鎖），保持/開關屏幕（完全喚醒鎖）。不正確使用喚醒鎖權限的應用程序可能導致CPU和手機屏幕保持開啟狀態，用戶不會察覺，就是它們造成明顯的電池消耗。
“Wakelock Detector” 顯示所有應用程序的喚醒鎖使用信息，甚至是一啟動就持有喚醒鎖的應用。默認顯示CPU喚醒鎖，按最長使用時間排序。另外，您可以選擇屏幕喚醒鎖類型來查看與屏幕相關的喚醒鎖。舉個例子，如果您的屏幕在屏幕超時後仍然開啟，或者您的屏幕時不時自動開啟，那麼您就可以選擇頂部的屏幕喚醒鎖類型（亮度圖標）來查看哪些喚醒鎖一直在喚醒您的屏幕。還有，如果您想看看正在運行的應用程序，那麼您可以將排序方式改為”活動“，它會將正在運行的應用程序顯示在頂部。更多細節，請參考設置中的常見問題。
主要功能：
# 顯示CPU喚醒鎖(局部喚醒鎖)和(完全喚醒鎖) ;
# 將應用程序關聯的喚醒鎖合併為可展開的視圖，有更好的用戶體驗;
# 當前正在運行的活動進程顯示為綠色;
# 可以按運行狀態，喚醒鎖時間和字母排序;
如何使用：
#1 安裝應用
#2 充電到90% 以上並所拔掉電源線（或者直接重啟手機）
#3 給點時間（1－2小時）來累積喚醒鎖使用信息
#4 運行“Wakelock Detector”，它會為您顯示所有的喚醒鎖信息！
#5 檢查在頂部的應用，如果它們的喚醒鎖使用時間很長，那您找到電池消耗過快的原因了！
*注意：喚醒鎖統計信息在第3步就開始收集
注意
我們致力於改進“Wakelock Detector”的性能，添加更多功能，用於解決用戶通常面對的喚醒鎖問題。我們會盡量查看你們所有的討論。而且我們知道程序目前還不是非常理想的。如果您在Play商店給出負面評價前，能先通過郵件聯繫我們，我們將十分感激。隨時歡迎您的反饋。
