如何以编程方式禁用“省电”模式。 （Android）

Question

Currently I'm trying to develop a 2D game for Android devices by using OpenGL ES , but Android OS makes it as painful as possible.

It look very nice and smoothly running at 60FPS by consuming all the battery it can. Then suddenly I've realized that. Enabling " Power save " mode ( Galaxy S III , etc), couses FPS drop to 40 .

So I've decided to increase game speed and limit timer to 40FPS , so it will be possible to play at 40FPS smoothly.

And here comes another problem. This times objects that moves are flickering randomly even if the max is FPS set to 30 and calculation/drawings are on the same thread. when " Power save " is disabled(Disabled from devices menu) it keep running smoothly.

In short " Power save " mode is slowing down app by slowing down OpenGL ES functions randomly even if it is not nessecery to drop FPS to 40 . (sometimes a function that takes 2-3ms to execute, takes 13-14ms and the others are running normaly)

I wonder if there is a way to disable "Power save" mode in code and enable it back on exit.

PS: To keep screen on I'm using next lines:

getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);

final PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE);
this.mWakeLock = pm.newWakeLock(PowerManager.SCREEN_BRIGHT_WAKE_LOCK, "DoNotDimScreen");
    this.mWakeLock.acquire();

也许这可以帮助您：

getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
