Welcome to the forums, Larry.

I'm sure you've examined your Application Manager area under "running" to see what services are running, thus your use of the task manager.

I'm thinking that your new device probably has a lot of bloatware,, but I'm also wondering if you've checked your syncing apps and widgets such as weather and social networking apps. They may be auto syncing by default and at too frequent of intervals. Check them all, even Gmail/email, news, etc, anything that syncs.

You may end up setting most of them to sync on demand, manually, rather than auto.
