Four US House Republicans, including the chairman of the Energy and Commerce Committee, on 12 January wrote Apple Inc chief executive Tim Cook asking him to answer questions about its disclosure that it slowed older iPhones with flagging batteries.
The California-based company apologized over the issue on 28 December, cut battery replacement costs and said it will change its software to show users whether their phone battery is good. The letter also said they were concerned about reports that an iPhone battery overheated and began to emit smoke in Switzerland.
US Senator John Thune, who chairs the Senate Commerce Committee, sent a similar letter to Apple on 9 January. Apple did not immediately respond to a request for comment 12 January.
