sudden battery drain after Galaxy S5 update

[Tech-Newb]

The same here... since the update two days ago, my Samsung S5 battery drainage has increased like 300%. That's crazy. Before my battery lasted 3days, now it doens't last even one day...
The strange thing that i noticed is, that this screen that shows how much % of battery was used by system and aplications shows after whole day, when battery was drained from 100% to 20%, that most battery was used by cell stanbdy 3%, android system 3%, screen 2%, etc... Why are those % so low? And what has drained my battery???

You revived a 1 year since last post thread XD. Can you post a screenshot on the battery usage and also the graph. In the lollipop, the battery usage monitor is diffrent from what is found in kitkat. It shows lower percent.
