That’s an issue, which has been discussed multiple times and will be discussed forever, however, I would like to remind everyone that mining is only for sufisticated hardware and not for mobile phones.

When mining in a smartphone you should understand clearly that:

- If it is a smartphone of your own than you would be unable to use it as anything except mining, otherwise it will bring you little or no income. So no Internet, Gaming or Phoning... Forget about it

- The phone battery will be worn out in no time - the battery cannot be overused - otherwise it will loose it’s capacity.

- Cooling - chipsets on mobiles aren’t at all aimed at working on the top of it’s speed for 24/7. This you will have to provide special coolling for that. Otherwise the phone will get overheated and might be damaged (or can even blow up)

- Android and iOS systems can be uploaded to professional computers which would easily outperform regular smartphones

The list can be continued, but you see the point - mining is for computers, not for phones.
