Samsung recently made an article about how to save battery in the News and Tips section of this app, but there are a few more ways to conserve battery. Using Max Power saving should be a last resort in saving battery, because there is not much you can do with your phone otherwise.
A way to save more battery that you may have not known is by taking advantage of the AMOLED display of your device. AMOLED is a type of display where every pixel is an LED, and everything black on your screen is just an LED that is not on. This conserves battery, and makes black shades look nicer. Applying dark themes and avoiding bright, white wallpapers can help reduce battery usage. As you know, Samsung's default UI is mainly white, and that can reduce battery life.
Some people may have told you this before, but you should disable radio functions you are not using. For example, turn off Location when you don't need it, or set it to battery saving. Or, disable NFC and only enable it when you need to use it. These are small things, but they can have a large affect on your battery.
Vibration is one of the major things that affects phone battery. There is a small motor in your phone that requires the power of your battery to make the phone vibrate. If you have keyboard tap vibrations, I recommend disabling it. You can also go one step further and tweak the vibration strength to your liking in the settings.
Of course, if you want to go that extra step, you can buy a battery case or a power bank. This might not be the best option because of all the bulk, but if you really need that extra power, it's worth it.
That's all I got, folks. Hopefully one or two of these tips helped you get better battery life. Thanks for your time!
Along with what @ProXx123 said (other than the "small motor" 😛) Disabling apps that you don't need or want to run (I use BK Disabler) as well as Greenifying apps - Denying apps that you don't want to access your Location or use Data (either WiFi or Cellular) Preventing apps from sending data back to their Source - Turning OFF WiFi during "sleep" Settings - Connections - WiFi - Advanced - Using Apps such as Better Battery Stats - GSam Battery Monitor - Wakelock Detector can help you to find which apps are using the most amount of your Battery and then you can decide how to deal with them 😊🐧
