Four U.S. House Republicans, including the chairman of the Energy and Commerce Committee, wrote Apple CEO Tim Cook on Thursday, asking him to answer questions about the company’s disclosure that it slowed older iPhones with flagging batteries, reports Reuters.
U.S. Senator John Thune, who chairs the Senate Commerce Committee, sent a similar letter to Apple on Tuesday. Apple has published an apology letter to customers in regards to “Batterygate” for slowing down older phones to compensate for erratic battery performance.
The tech giant is offering $29 replacement batteries for those with an iPhone 6 or later. The discount, which represents a $50 savings, starts in late January and ends in December 2018. Apple will also add more battery health information to iOS to let users know when the battery begins to compromise performance.
