In addition to a series of murder applications in the United States and a state investigation in France, Apple has agreed that iOS is missing out on Iphone devices with outdated batteries so that they can not be shut down suddenly under severe strain that US politicians at the highest level get into.

On Tuesday, the President of the Senate Commissions Commitment to Apple wrote for more information about the depreciation of older Iphone models, and on Friday, four Republican members of the House of Representatives sent another letter, reports Reuters.

Greg Walden, chairman of the Energy and Trade Committee, belongs to those who wrote the letter addressed to Tim Cook.

Exactly what the legislators want to know is unknown, but in addition to Apple having slowed down Iphone devices with worn batteries they should also have expressed concern about a report about a smoking Iphone in Switzerland.
