If you have a battery Drain problem after upgrade:

[N1520]

-Turn off background Tasks you don't need ( be reminded Notifications won't work if you do so )
-Delete Skype. ( Don't disable it, f**** delete it )
-make sure your brightness on AUTO, or even better at low
-Location services OFF
-Email account syncing to manual or hourly for accounts that don't require immediate attention. Same goes for calendars.
-Go to your MS account, make sure no services have access to your account, such as twitter or Google.
-Battery saver.

That should do it

I have 2 windows phones: 8X and 1520 .. Disconnected from charger at 7 AM, and at 6 PM : 8X at 54%, 1520 at 75% .. Moderate use.

1) Go to your programs and then Battery Saver and under Usage check to see if any app is using a significant amount of battery.
2) For app updates, go to Store, click on ... and Settings. If you are not using WiFi, make sure "Only get updates over Wi-Fi" is turned off, and then click Check for Updates. Then go back to the Store and click ... again and look under Downloads to see if it is updating any. Here you can click History and it should show which apps are updated.
3) I would suggest trying to uninstall and reinstall these apps. Some apps might not work properly with 8.1 until they are updated.
4) This is likely a firmware issue. You may need to wait until there is official Lumia Cyan update available.
5) Do you have the regular Facebook app installed too? Is 1 of the notifications from it and 1 from messenger? You can disable the one from the Facebook app by going into it, under Settings and Notifications, try turning off Messages. If the problem persists, try uninstalling and reinstalling both apps and then reconfigure.
