Heavy battery drain after Denim update in Lumia 520

[srm_harish]

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.

I think it's normal, the same happened after cyan, what helped me a charging cycle, note my battery works very good
