s5 battery draining very very fast !!!!

[Solo 8]

So my samsung galaxy s5 is 2 months old now and the battery is no longer good as it used to be. Im loosing 1% each 3 min and my battery is draining at a high rate (20 %) overnight. I have read many threads, made a factory reset, turned off location services, dimmed the brightness, drained the battery and recharged it but nothing is working. My battery used to last 3 days without charging but now it wont even last 7 hours!!!! android OS is using 50% of the battery and i know it shouldn't but i cant find any solution for this problem. Plz guys i need serious help

Check these two:

'Is Android system making my battery drain?'

'LG G2 high battery drain lately'

You may have to scroll a long way before you find them, but they're there.
