Bloody Wifi Power consumption when screen is off
I was very annoyed by the battery consumption of my Wifi when in sleep mode. After 2 days normal use (few calls) the battery was drained. After inspecting with the Testing app > Battery History it showed almost 100% battery consumption for Wifi Running. WTF? My screen was off most of the time that 48 hours and in advanced wifi settings I told Wifi to goto sleep when the Screen is off. "Listen to the boss bloody phone"
HELP Google!

Allthough it is for older version finding the settings db was easy. So of we go...
Copy it from the phone to the PC
Code:
C:\Temp\_samsung i5500\
-> adb pull /data/data/com.android.providers.settings/databases/settings.db
1088 KB/s (0 bytes in 34816.000s)
-->>>> EDIT settings.db with SQLite () see pictures (
http://www.sqlite.org free version)
- add a new record in secure called
wifi_idle_ms and set it to 10000
(default is 15 minutes I found somewhere = 15 x 60 x 1000)
- add a new record in system called
wifi_watchdog_on and set it to 1
(Dunno what the default is for wifi_watchdog_on, set it to 0 if you don't want it)
After editing copy it back to the phone
Code:
C:\Temp\_samsung i5500\
-> adb push settings.db /data/data/com.android.providers.settings/databases
2176 KB/s (0 bytes in 34816.000s)
After that immidiately reboot the phone
The settings are referenced in the system/framework/services.odex or framework.odex file.
Use google for more settings and their specific table (system or secure) in settings.db
Cheers
ps: just for fun: create in system table a record show_processes with value 1
this will show all running processes and cpu load/avarage in the right upper corner after reboot
