Apple iPhone battery drain since update iOS11.2.1

Apple said it is sorry for making the batteries on the older iPhones slow down but it has really hampered my enjoyment of the phone. Just today the press said Apple would replace the old batteries for users like myself at a discounted price but that won't happen till end of January. I just wanted to ask if anyone else has had fast battery drainage since upgrading to iOS 11 and has an older phone? I see no real need to have done this to older phones as there are many, many users out in the real world who are affected by this software UPGRADE!!
