There are dozens of battery threads here asking the same thing. The answer will always be the same.
No one can answer this question for you. Everyone's usage will be different as there are dozens of variables that can impact your battery life. Apps installed, cell service, settings, screen brightness and of course usage. No two phones will have the same battery life, even if configured the same because of all the variables. Just use the phone. If you think you are having problems, contact Apple.
