Battery draining problem

[itsmewasim]

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.

Hard reset-hard reset-hard reset. MDK 22 is correct...it really does sort itself out after a few days-week.

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.
