Battery Problems

Hi there. I'm new to smartphones (i just got my first one recently) from the minute my S7 edge came out of the box, the battery life is terrible. I see so many people raving about the S7's battery life yet from the minute I turn it on from being fully charged it has already lost 3 percent and I have under 10 hours left. I haven't downloaded any apps and am barely using it. Does anyone have any suggestions as to how I can get the 17-22 hours of battery life that other people seem to be getting? I don't know if this is a silly question but like I said, i'm new to smartphones. Thanks for any assistance you may be able to offer me. Have a lovely day.

Welcome to the forums young lady! If you fully charge the device, let it go down to 50%, then look in the battery settings, it will give you a breakdown of where the juice is going. Your screen will be the biggest gobbler of power usually..
In any case, do that, then come back and tell us so we can troubleshoot with you.
Getting a full day out of most smartphones is not bad these days.
When you turn it on, it has to boot up all the apps, log into network etc, so you do lose a couple of percent at start up.
Make sure you have all auto download /updates turned off, keep your screen timeout short, reduce synch activities to minimum.
There are myriad settings on your amazing device, trawl around on the forums and read the many articles on setting up a new device and battery optimisation.
Do join the forum and tell us how you fare 🙃

If I might expand on Tim1954's reply --

Charge up to 100%, then let it drain to 20-30% with normal usage, without charging in between. Then show us:

1. The main Settings>Battery screen.
2. The fullscreen battery graph screen (which shows Awake time and Cell Signal Strength).
3. The Screen category (to see total Screen On time).
4. The Cell Standby category, if present (to see Time Without Signal).

You might have to install a 3rd party battery monitor, like GSam Battery Monitor, to get the Cell Signal Strength graph.

Some things might not show on the battery stats, but it gives you a great start.
Turning off NFC, Quick Connect, Bluetooth (if it's not needed), turning your WiFi off when you aren't connected) are good starts.

Other things include going into your settings, clicking on more, and turning off Nearby Device Scanning and Media Share / Nearby Sharing.

Disabling Smart Switch (located in the Advanced menu in your WiFi)

Always On Display is one of those neat features with these phones, and it's not supposed to drain your battery fast, so that's up to you.

If after a few days or charges, you are still worried about battery life, then you may want to look into disabling unused / unneeded apps.

There are a lot of posts in these forums about how to / what apps are safe to disable, but don't jump straight to the nuclear option before fiddling with the settings first.
