@Neil_za: I'm sorry to hear of your disappointment. Sadly the more apps you introduce to your device, the more battery usage you will experience, both directly through interacting with the apps, and indirectly via background processes. If you head to Settings > Battery and device care > Battery > Tap on the usage graph, you will find a breakdown of your usage. If you see anything listed that is using an abnormal amount of battery, tap on it, select 'Limit usage' at the bottom of the screen, and you can add it to the Sleeping or Deep Sleeping apps section. Sleeping apps will only run in the background occasionally, while deep sleeping apps will never run in the background, and will only work when you open them. I hope this helps.
