Why does my brand new iPhone 7 battery drain quickly?

Question

I just upgraded to the iPhone 7 and it's battery drains faster than my old Samsung 5. I took it back to the store and it was replaced. Now the replacement iPhone's battery dies quickly as well. I've only had this phone for 3 days. The battery DOES charge faster but that's useless unless you want to walk around w/ a charger 24/7. I turned my setting to low battery usage mode already and that didn't change anything. I did a soft reset on the phone as well. What to do?

I've been an iPhone user a long time. I feel my battery dies quickly but i'm also on my phone every second of the day via Spotify, Instagram, YouTube, etc. Always doing something.

The key is your more than likely restoring your device from backup. There are TONs of settings that play a part in battery drain. I've spent hours and hours trying to optimize my device.

I would suggest you reset your device to factory and use it a bit before restoring from backup. See how it does. I do this sometimes and just turn on contacts etc. via iCloud.

Things to consider:

* Settings > Privacy > Location Services > check out which apps are using your location all the time. I only allow apps to use my location all the time that I have no choice if I want to use the app. e.g. Waze
* Settings > Display & Brightness > auto-brightness
* Settings > General > Background App Refresh > check out which apps are refreshing in the background. Turn off ones you don't want to do such or turn them all off via the toggle on the top
