My just bought Samsung galaxy s5 battery drain quickly

I have purchased a Samsung Galaxy S5 from the store. I open it and I begin by charging it for the first time, but without turning it on. The battery was 61%, so I waited until 100%. After that, I turned on the phone and proceeded to set it up. The version of Android was 5.0 Lollipop (I don't know how this is possible as I thought I need to update it myself from 4.4.2 to 5.0).

While I was entering in the information for the first time, the battery suddenly fell from 100% to 95% in just 5 to 10 minutes, during the first steps where I had to create a Google account and set up my phone options.

I heard rumors that 5.0 Lollipop drains the battery quickly so I downgraded to 4.4.2 KitKat with the hope that it'll fix the battery problem. I downgraded successfully without error.

I have the same problem—the interesting thing is that I didn't download more than 5 apps. I only have Skype, Facebook, Messenger, WhatsApp, Viber and Instagram. All the other apps are from the phone itself.

Whenever I go to WhatsApp to check messages or chat (or anywhere else), the battery falls 1% after 3 minutes. All of the NFC options, location options and other unnecessary options are turned off. The brightness is also on low. In 15 minutes of use I notice that the battery falls from 80% to 65% or 60%.

I have already done a factory reset twice, while I was downgrading to KitKat 4.4.2.

I'm a new user of a Samsung Galaxy S5. Is this normal or abnormal? What is the problem and how can I resolve it?

The first thing to always try is adjusting the brightness. If after you test that and there is still a problem, navigate to your settings and play around with usage settings such as when data is refreshed or how apps run in the background when not in use. In my experience, Lollipop is not the culprit of a poor battery.

Good Luck!
