    So I was really worried about how fast my battery was draining on my L521 on 8.1 so I messed around with few settings trying to find the culprit. I found that disabling Cortana completely (settings>applications>Cortana) and following the required restart had my battery running like it did in 8.0, so its worth a try if you're having battery issues too.

    I used cortana for an hour. She was great but unfortunately, she was a battery juicer along with location service. I uninstalled her and turned off location services because cortana and location service are for smartphone with 3,000 - 4,000 mah battery.
