With all due respect Hookbill, I think, had the phone come with the extended life battery in the first place which should last 12 hrs. having to buy a second to last 6 hrs., or, 12 hrs. more makes sense. I just feel like as a consumer the product should have to work as other similar products do. I was told the batt. would give 6.5 hrs. of "talk" time, not 6.5 hrs. of batt. life. I feel cheated! I'm sorry if I took your thread off track it just gets me when I feel scammed and I had to vent. Thanks for listening. My next phone contract is due in November. Hopefully by then this issue will have been resolved. Because I really want to be a Thunderbolt owner.
