There is certainly a problem with T-Mobile phones: https://support.t-mobile.com/thread/146510 with battery life, but also with general speed--the phones are incredibly slow and unresponsive. See this thread: https://support.t-mobile.com/message/651351#651351. Clearing cache partition solves a part of the problem of battery drain. But the phone is still extremely slow. WiFi on drains battery faster than usual. WiFi off does not appear to have the fast drain. Please acknowledge this issue and send out an OTA reversion to Nougat for S7 T-Mobile phones until you can get a fix. This is not fair for customers to have their phones ruined by a mandatory OTA. Nobody at SS has acknowledged the issue. If you will at least acknowledge the issue, reproduce it, and start working on it, we can be patient since there is hope. Currently there is no hope for us because nobody even acknowledges this huge problem. Please acknowledge the problem!
