You could try an app like AutoPilot (com.verobapps.Autopilot) to avoid the manual switching.
Also, there are a lot of apps that can trigger battery problems (via bad coding usually). Try an app like Better Battery Monitor or Gsam battery monitor to definitely point to the cause. If you're right about the issue, "cell standby" will be eating your battery. Otherwise, the most common problem I see is apps preventing phone from properly sleeping.
