WP 8.1 drains battery soo fast...

[Kurtz1993]

I thought this issue was corrected with the dev preview updates, but it seems that it got worse in my Lumia 520.

Battery lasts up to 26hrs if I'm lucky, when on WP 8 it was up to 50 -52 hrs.

Common activites:
Wifi connected all day.
Opening Facebook, Twitter, Messenger very often.
Reading articles in WPCentral App.
Web browsing.
Open MixRadio like once a day for 15 - 20 minutes.
Watch MetroTube videos at 360p

I consider 26 hour battery life excellent on a smartphone.

I've never expected to get more than 18 hours on a single charge since I've been using smartphones. I always charge my devices every night overnight when I go to sleep. One cannot overcharge Lithium ion batteries, and Lithium ion batteries do best when topped off regularly and not allowed to drain too low repeatedly.
