After the system update the other day I experienced similar issues. Battery indicator showed a question mark on the lock screen. Phone was warm. Battery charge showed quick decline in the top menu. Frequent freezing. Won't get 4G on my carrier. I notice a lot of change in the UI. After a few reboots, the battery indicator looks normal and discharge rate is normal, but still freezes frequently.
