    After updating my Lumia 720 to denim my battery drains so fast ! I have turned off background data for many apps in battery saver . If i use continuously my battery backup is only 4 - 5 hours. During cyan it was good.. How to recover from this problem?

    FIRST - when you took Denim, it's always a good idea to reboot - AFTER all the forced reboots. Better, a Hard Reset (after a BACKUP) with a Restore.

    That being said, after numerous upgrades, it will sort itself out - give it a week, before you punt the phone.

    Check Battery Saver, it might be Cortana (or one of your email accounts, people, etc,) absorbing the Internet.

    To elaborate on this ...

    The ABSOLUTE best way to take an update is :
    - Backup your device
    - Hard Reset
    - Sign in
    - Take the Update
    - AFTER all the forced reboots, reboot one more time
    - Hard reset (this is to get the option to restore)
    - Restore from Backup (IF you have the time, do a clean install of all your apps)
    - THEN, it'll really seem FASTER

    my work here is DONE.

    From when my 24 yo was a kid ' ... clean up, clean up, everybody, everywhere ... ', that damn purple dinosaur!
