Just tried the "Reset network settings" option, and rejoined home Wi-Fi. Prior to rejoining home WiFi ran a Speedtest and got 43.7Mbps down, 11.25 up.
Will see if this makes a difference at work tomorrow for mobile signal and battery drain, along with not seeing the constant Wi-Fi on/off toggling and problems joining home Wi-Fi after returning from work.
Yesterday when out around town in various locations Speedtest results were at best 13.73 up and 12.38 down. Signal strength was likely varied at the different locations, particularly with many people in the same area. Earlier this year was able to get 74.70 Mbps down 11.97 up at home. Realize that there have been a few OS updates since then, and that Verizon network variances among other factors can influence results.
