Android app prevent device to sleep
Tanapol E. 6 years ago in Applications / i3 Pro • updated by Aleksandr Romanov (CTO) 6 years ago • 6
Android app 1.1.7/Beta
When user press power button while still in i3pro app
Android Device will go to sleep state then wake up immediately(screen still off)
and when user press power button again it will skip all lock screen and show i3pro app
this will drain Android Device battery eventif screen is off
because of i3pro continue to work in background
it there anyway to disable i3pro app running in background on some panel project?

I do not quite understand. How do you understand that the device has woken up if the screen is still off?
Please specify the model of the device, as well as the version of Android, on which you observe such a problem.
I test on
Google Nexus 6P - 7.1.2
Samsung Note 5 - 7.0
I notice this problem on 6P first because
when I press device power button, 6P will play some "turn off sound" and screen will be off
and when I press device power again 6P will play some "turn on sound" and screen will be on then showing lock screen
but when i3 is running and I press power button i can hear "turn off sound" then "turn on sound" but screen remain off
if I press device power button again screen will show i3 without any lock screen
(I think this state in Android called WAKE_LOCK,screen off but some app still running )
The problem is in this state i3 continue drain my phone battery
this can easily test by 100% charge your phone, unplug, open i3 app, power button, then phone screen will off
then just let phone remain in that state for a few hour without using
when you turn on you phone again battery will be very low
if you check which app is draining battery in Setting->Battery> Use since last full charge
I3 Pro will be in top of the list,
if you click in i3 Pro, see "Keep awake" time you will see that i3 Pro keep device awake all the time
even if screen is remain off.
Please note that state is OK to use with device that always have adapter plug in
but for mobile phone if user forgot to close i3 app before turn off phone screen
i3 will continue running in that background
(I also do some additional test by let i3 send some feedback by using IR.SetInterval
to see if i3 still running JS script in this state or not,
result : i3 will not run any JS nor sending anything in this state)
Hello, is your problem still unresolved?
problem remain the same but now i have workaround by add "exit" button to panel that use on smart phone.
I apologize for not being able to repeat this situation and take action to correct it.
