I'm mining right now i just set it at 20% to keep the phone and battery from getting warm.
Not to risk to use the mining on mobile. It some time it will heat and born mobile. So don't use it. It's not safe for use. So you will use the disk. Before use the mining you will learn it. It needs for more power and cooling place. It needs more power to use. So thing and plan to use. You will use the mining properly. So will get more income and get more information. Mining is network process. So connect the network for mining work.
