My samsung galaxy ace keeps turning itself off even when im not using it, it will just turn off for no reason and when i try and find out why it has, i cant find anything. One thing i have found though is that when i click on something on the settings it says that something called cell standby is using up 53% of the battery, does anyone know what that is as i am confused and would like my phone to stay on or is it just a faulty phone that i cant fix.
