    1. Check what app is consuming battery the most, in Battery Saver.
    2. I'd suggest to use w/o Cortana (if you have it enabled).
    3. If the two options above will not help, it's quite likely you need another battery.

    P.S. When did the high battery drain begin, since you bought the device or a specific moment..?
