Apps are not designed with battery conservation in mind. Many apps are designed without regard to how long they’ll last between charges. Because of this, they tend to use a lot of resources and drain batteries unnecessarily.
Tinder uses so much battery because it is constantly checking for updates, downloading data from the internet, and other things that require constant attention. Such apps are not designed to run in the background. They are designed to run in the foreground. Even when they are running in the background, they consume battery power.
If your phone has a lot of apps installed, this can add up to a significant amount of battery drain. You should only have a few apps installed on your device at any given time.
Also, most apps are designed to perform well over Wi-Fi connections, but many people still rely on cellular data to access the internet. Try to connect to Wi-Fi whenever possible.
