    I recently updated my Lumia 520 to denium, after the update there has been a drastic battery drain..

    it is reducing from 40% to 0% in 3 hrs.. in idle state.

    Today i tried disabling all the applications through battery saver, but still my phone last only for 7 hrs with normal usage.

    half hour calling, no whats up, 10 min of Video play back, thats all i did.

    Any one facing the same issue??? Cyan was much better than Denium.

    I raised the issue via Twitter to Microsoft, however they have to get back with the response.

    If u can then do a hard reset after backing up all data, that usually fixes all issues that come with a new update.
