Samsung: Find out the battery status

Before you can optimise the battery usage of your Samsung mobile phone, first familiarise yourself with the status of the rechargeable battery. If the rechargeable battery, for example, of older models, such as the Samsung Galaxy A51, S9 or S10, drains quickly, this may be due to age-related wear. If, however, the rechargeable battery of the Samsung Galaxy S24, S23 or S22 drains quickly, there are normally other reasons for this.

Information about the rechargeable battery status can be found in the preinstalled app Samsung Members. Tap on Support and then start the diagnostics. If, according to the diagnostics, the battery is functioning normally, everything is okay. However, if problems are found, there are further measures you can turn to – and, if necessary, you can have the battery replaced with a new one.

Identify Android power guzzlers

If the Samsung rechargeable battery drains quickly, you can easily identify the biggest Android power guzzlers. Go to Settings > Battery. Under Battery usage or Battery consumption, you can see which Android apps cause the biggest battery usage. These are usually the apps you use most often. However, identify energy-hungry apps that you hardly use, then limit their background use or uninstall the power guzzlers from your Android mobile phone. Even just a few apps can cause your Samsung battery to drain quickly.

Set the display brightness

Whether a Galaxy S9, S10, A51 or S23, S24: The brighter the display, the faster the Samsung battery is drained. You can set the display brightness on Samsung smartphones for a longer battery life. Go to Settings > Display and then set the display brightness. To prevent your Samsung battery from draining so quickly, choose the darkest possible setting and activate Adaptive Brightness so that the brightness adapts to the ambient light.

Switch off the always-on display (AOD)

Thanks to the always-on display, you can always have an active screen shown to you on your Samsung device. The date, time and notifications are thus always in your view. This is handy, but can also be the reason for high battery usage on your Android. To protect your battery, it’s recommended to deactivate the always-on display. Go to Settings > Lock screen and deactivate the always-on display using the slide control.

Deactivate location and connection services

WLAN, Bluetooth, GPS, NFC and all other location and connection services are constantly working in the background. This can also cause your Samsung battery to drain fast. So, pull the status bar down and always deactivate unnecessary connection and location services if you don’t need them at the moment. For example, do without WLAN when you’re on the move and switch GPS off at home to manually optimise the battery usage of your Samsung mobile phone.

Activate Android energy-saving mode

Samsung itself offers a setting to prevent high battery consumption: energy-saving mode. You can easily activate this by clicking on the battery symbol in the quick settings. This automatically switches off some services to save battery power if your Samsung battery is draining quickly. You can determine exactly which smartphone features are restricted under Settings > Battery > Power saving mode for your Samsung mobile phone.

Perform software updates

We recommend you regularly perform software updates so you are always using the current Android version for your model. Alongside security patches, an update of this kind often also increases efficiency to relieve pressure on the processor. So, if your Samsung battery drains quickly and a software update is available, first back up all your important data and then start the update. Also keep your apps up to date by updating them via the Play Store.

Charging a Samsung correctly

You can also extend the lifespan of the battery by charging the phone battery properly. Especially with new devices, the correct handling of the rechargeable battery makes a significant contribution to making sure the rechargeable battery has a long lifespan. This is why you should only charge it when needed and disconnect your Galaxy as soon as it is fully charged.
