i have a nexus 6 and its ruining android 7. its better then samsung devices, but it has its own problems. i run the screen at min brightness because thats the only way i can get reasonable battery life. my car is parked -2 so i lose signal every time i have to go there. and sometimes i have to restart the device to get the signal back ( no tricks like airlaine mode work) the ui sometimes gets so slow i dont know why.
