Windows 8.1 draining battery

[fiknahs_osei]

Hi guys, so I know most of y'all got the 8.1 dev preview and its pretty cool no doubt even on Lumia 520. Just a lil problem tho, my battery drops like crazy even when cortana and location is switched off. Its not my apps either cos I reset da phone had no apps on it and still.... Any ideas guys?? Issue started after the upgrade. Thanks
