I updated to 7.1.1 yesterday. I noticed my battery life seems to have gotten worse. Before the update I was getting 5-7 SoT. Mostly connected to WiFi with intermittent cellular usage. Always have had good connection. I have continued to have good connection since the update but I noticed that my SoT was about 3.5 hours today which is the worst I have had since getting the device. Has anyone else noticed a difference, good or bad, with the 7.1.1 update?
