More Tips for Better Battery Life

If apps in the overview are using a lot of battery in the background, it can help to force a stop. Android version 8 Oreo or higher also has built-in battery optimization that automatically reduces background activity to a minimum. The option can be found in the battery settings.

TECHNOLOGY BUTTON also has an overview of the biggest battery guzzlers. Some of the apps on the list might surprise you.

You save the battery by avoiding certain things. The battery loses a lot of its capacity when it is exposed to heat over a long period of time. It is therefore advisable not to use the smartphone while charging so that no additional heat is generated.

The battery capacity also decreases permanently if the cells are always fully charged and discharged. The battery level is optimal for the “health” of the cells between 20 and 80 percent. Therefore, try not to always charge the smartphone to 100 percent, but if possible to unplug it at 80-90 percent. Some manufacturers such as Apple already have a built-in protection function that only charges the smartphone up to 80 percent at night.
