    Not all 1520's function well with Windows 10 Mobile.

    Look at all of the settings and turn off things that you don't use regularly - NFC. Bluetooth, Location, etc. If there's any turned on, then see how battery life changes with them turned off.

    Also take a look at your background tasks to see which have been enabled after the upgrade (Settings-->System->Battery Saver->Battery use) - disable any apps that you don't want to work in the background (there are many apps that I only want to work when I open them manually)

    If neither of those fix the battery life, try:

    1. Try a soft reset (press and hold power button until you get prompted to slide the locks screen down). Restart the device and see if the battery life improved
    2. Try a hard reset (Settings->System->About). Ensure that you have a recent backup before doing this.

    If option 1 doesn't work, try 2.

    With battery saver on and location off, battery is MUCH better, and backlight on low.

    But then u get no notifications

    I never found one. Some 1520's and some 1020's simply won't update. W10M will install but it will run like half the code didn't make it, at least on the 1520 I have.
