New OTA update pushed through recently for T-Mobile has caused the device to overheat constantly and run sluggish ontop of draining the battery. I used to get over a day's usage out of my phone before charging the battery and that would only have been down to about 50% at that point. It was amazing. Then the update came through and now I'm charging almost every few hours. Going from 100 to zero almost in the blink of an eye. A full charge lasts only a few hours now. And I keep getting warnings that the CPU is overloaded and needs to restart so the device is constantly restarting now. All since this OTA update. Someone's got some serious explaining to do. My device is basically useless at this point.
