Yeah tried both, also with all the developer options enabled a few pages back.
The other thing that annoyed me was if you didn't kill off all your apps at night it would drain 30-40% over night. My 5S dropped 3% last night first night of use.
Maybe you are running some funny apps to drain your battery 30 to 40 percent overnight. This is definitely not normal. You should have been wiser to know this. But then again you are not, by making erroneous comparison which shows you have some grudge to settle.
Most online reviews gave s5 as having good to great battery life.
My note3 drops about 0.3 to 0.8 percent standby. This is with full load of apps like Line, Whatsapp, fb, tasker, s health, ip Webcam etc plus at least about 20 widgets on homescreen.
