Intel wants to get into more phones.  They are replaced so often - it's a good business to be in.

Actually, that's not true. The margins on phone chips are razor thin. Intel are required to maintain 60% gross margin by their major investors, so outright selling phone chips in place of current competitors is impossible for them.

Well, this site from Intel seems to disagree with that:  http://www.intel.com/content/www/us/en/smartphones/smartphones.html

"Smartphones with Intel Inside®"

The main reason for Intel to chase phones and tablets is mostly to try and keep x86 as relevent as possible, only three manufacturers actually create x86 processors, two of which have an insignificant market share, thus Intel by extension has a monopoly on the x86 market.
If ARM gains traction, then the value of x86 declines as OEM's have other alternatives that are potentially cheaper, not a good proposition for Intel as suddenly it has dozens more competitors.

Thus they *must* compete with ARM.
Intel have already released mobile processors utilising Atom (Aka. Medfield and it's derivatives), which were not only faster, but more-often cheaper than their ARM equivalents, the largest design win however was with Samsungs Galaxy Tab 3 10.1, a mid-range tablet.
