Xamarin wakelock

Question

I use PowerManager.WakeLock in my project to keep running my app in sleep mode, it is working great but this consumes a lot of energy and the device gets hot. What else should I do to keep my app running without a lot of energy?

My codes

PowerManager.WakeLock wakelock = default;
PowerManager pmanager = (PowerManager)GetSystemService("Power");
            wakelock = pmanager.NewWakeLock(WakeLockFlags.Partial, "test");
            wakelock.SetReferenceCounted(false);
            wakelock.Acquire();
