Apple probably paid Qualcomm between $5 billion and $6 billion to settle the litigation between the two companies, UBS analyst Timothy Arcuri estimated in a note distributed on Thursday.

Apple probably also agreed to pay between $8 and $9 in patent royalties per iPhone, estimated UBS, based on Qualcomm's guidance that it expects earnings per share to increase by $2 as a result of the settlement.
