Mine isn't quite THAT bad. But I will say that battery life has been pretty abysmal with this phone. Maybe because I'm coming from an iPhone? IDK. Either way I hope you find a solution to your problem. Was the phone recently water damaged? And/or exposed to high amounts of intense heat?
The only complaint I carry about this phone is the seemingly subpar battery life. And it doesn't seem as well supported as other Moto phones have been in the past, even under Lenovo leadership.
