I am not buying this. Not only the mining process would be extremely slow and resource-hungry, but also very unyielding, since processing power needed to generate currency is well above what a smartphone can do. Besides, any user that has his device drained in a couple of hours would recourse to any means necessary to solve that, including factory reset. I call complete BS on this "find" from, guess who? two companies that want to sell you their apps. As a complete irony, as of my writing, the first 3 comments on this article are spam, 2 of them linking to spamming websites.
LOL bit coin mining on a cell phone even a quad core is not powerful enough to mine anything hell even a top end gaming system does not have enough power to break even on the power cost used to mine bitcoins.CPU's are useless for bitcoin mining the difficulty level is much to high even for GPU mining.
