Android - lack of Inputs Touches slows framerate

Hi,

Very sorry in advance if someone described my problem, especially if it was solved. I was searching on Android/Unity forums couple of days to find answers to very weird behavior of my game while testing and found nothing.

So, I've made simple game 2d with some 3d effects. While testing game on my tablet (Samsung Galaxy Tab 3 Lite) on Android 4.2.2 I've noticed fall of framerate from 25-30 to 5-7FPS when not touching screen. Problem appear after deploy application to tablet.

When I touch the screen framerate jumps to 25-30 fps. So my question is Android somehow slows my aplication when there is no input action (maybe change state to save energy)?

I tested it on better hardware (Galaxy S4, Lumia 730) and problem not occured (maybe some slow but not visible).

I think, I tried every combination of graphics changes (with change compression every texture to max 128 for android) and check is something strange happens in script where theres no input action but no result.

Btw I'm using graphics 2Art by Manufactura.

 

I'm seeing the same on my Oneplus one. I think it's a power saving feature of the phone or android itself. I wonder if it can be turned off or something.

 

Unfortunately, the solution with "Screen.sleepTimeout = SleepTimeout.NeverSleep;" didn't help. Thanks for reply, If I find solution I'll inform you guys here.

Having the same problem on Oneplus 3, din't have it on oneplus 1 tough
Using the latest version of unity (5.4.0f3)



Might have figured out, for some reason it doesn't like UnityEngine.GUI, weird..

 

Sorry for bumping this old topic, but I have same issue. Did any of you found a way to "fix" this?
