Welcome to Android Central.

At the end of a normal day's use, go to Settings, Battery, and note the main users of charge.
Give us an idea also of the strength of your signal....the number of signal bars shown in the status bar will give us a good enough idea, as long as they don't vary much throughout the day.
With this info we may be able to make a diagnosis.

You say 'new battery life'....if you have just bought a new battery, that may be the cause of the trouble, if it was one of low quality.
