Verizon iPhone 4s Battery Life

[linder5]

Somewhere I read about sending a code or dialing a number to send to Verizon that would help extend the battery life of the iPhone 4s. Not sure what that does, if it helps at all, but I cannot seem to find it. If anyone has any information on that topic, would you please let me know...

Thank you.

You can dial *228 and do option 1 to program (or reprogram) your phone, and option 2 to update your roaming capabilities.

That's the only number/code that I've seen that you can dial.
