OREO Update Rendered my phone USELESS. Battery now dies after less than 2 hours.
I Have Galaxy S7 Which Since getting the OREO update now dies after less than 2 hours of being unplugged! In battery usage it now Shows "Android System" as using up 50% of my battery yesterday! also the cpu never idles at 307mhz anymore now it idles around 1200 which explains why battery life is so terrible now and why the device is so slow! Also I have already done a factory reset. I feel like this is an attempt to make my current phone so undesirable and to persuade me into buying a new phone (this seems illegal) please advise. my phone was purchased in may of 2017 so out of warranty -_-
