My battery life on iOs 7.1 Beta 4 has gone worst than ever.

From this all, 30 mins is the music playback. Through out I had wifi connected 70% time. Its after resetting all the settings to default, logging out and in to all accounts including fb, dropbox, icloud, appstore, imessage, facetime etc and switching off location services for some and Background app refresh for all apps.
What do I do in order to make this phone at least usable.
