At the phone start, deep sleep mode works fine, but as soon as i receive an email or SMS, the phone will never go back in powersaving mode. Just as if the service crashed and the phone still "Awake". I've tested several solutions and apps:
- Deep Sleep Battery Saver: Failed
- One power guard: Failed
- Powersaving tweaks from Pimpmyrom: Failed
Of course i've checked if a service or apps aren't involved in the problem, but there is nothing. I've checked with Betterbatterystats, wakelock detector...Deep Sleep mode just crash and never restart . And we are a several people in this case...
i imagine the gotosleep void in powermanager can't do his job
"public void goToSleep (long time)
Added in API level 1
Forces the device to go to sleep.
Overrides all the wake locks that are held. This is what happens when the power key is pressed to turn off the screen.
Requires the DEVICE_POWER permission.
The time when the request to go to sleep was issued, in the uptimeMillis() time base. This timestamp is used to correctly order the go to sleep request with other power management functions. It should be set to the timestamp of the input event that caused the request to go to sleep.
