I have the Galaxy s7, but it seems my battery is already declining and I have only had it for 8 months. I've done all the tips and tricks to improve battery life, turning wiFi off when not using, location off, always on display off, cleaning excess background apps at least once a day....what gives?

How do,you notice the declining battery? What has changed for you?
I've been starting to have to charge it daily now, it usually used to last me a full day and a half. I would be charging it the next day and it still wouldnt really need charging. But now it gets to 50% really easily in one day.
And I havnt really been using it that much more either. Still around the same amount I used to always use it. My brightness is even on low. Like way less than half brightness. Like 30% brightness. I dont even watch videos on it either really.
You either change the battery or the phone.

There is the option of selecting MID (Medium) or MAX power saving modes. Swipe down from the top of your screen (twice) and tap the 'Power Saving' icon. Tap MID and then Apply, to set the medium power saving mode. You can also tap 'Customize' to tweak or experiment with specific settings; (e.g. Speed Limiter, which limits the maximum CPU speed to 70%).
If the phones' screen resolution is set to WQHD, set it to FHD or HD. (Settings > Display > Screen resolution). 

Go to: Settings > Device Maintenance > tap the Battery icon. Scroll down and see which apps are using the most amount of battery per hour. Select the apps, then tap the 'Save Power' button to stop the apps from using the battery when you're not using them.

Back to the Device Maintenance window, check the Performance Mode icon and make sure it is set to Optimized.

Hopefully, you'll get a little more mileage out of the battery.

With Samsung's when the battery begins to not last as long I back everything up to the cloud and perform a factory reset and things usually go back to normal. Definitely try Rikkster suggestions first.
