Step-by-Step Repair
- 1
Check which apps are draining your battery
Go to Settings > Battery and Device Care > Battery. Tap the usage graph to see which apps used the most battery. If an app you barely use is high on the list, it is running too much in the background. Tap it and select Restrict Background Usage.

Turn on Adaptive Battery and optimize settings
Go to Settings > Battery and Device Care > Battery > More Battery Settings. Turn on Adaptive Battery — this learns your usage patterns and limits battery for apps you rarely use. Also turn on Adaptive Brightness (Settings > Display) to reduce screen power usage.
- 3
Reduce screen brightness and timeout
The screen is the biggest battery drain. Lower your brightness or use auto-brightness. Set your screen timeout to 30 seconds (Settings > Display > Screen Timeout). Also turn off Always-On Display if it is enabled — it uses more battery than most people realize.
- 4
Disable unnecessary features
Turn off features you do not actively use: Bluetooth (if not using wireless earbuds), NFC, Location (or set it to While Using App Only for each app), 5G (switch to LTE in Settings > Connections > Mobile Networks if you do not need 5G speeds), and sync for apps that do not need real-time updates.
- 5
Update your phone and clear the cache
Go to Settings > Software Update and install any available update. Then clear the system cache: power off the phone, hold Volume Up + Power until the Samsung logo appears, use the volume buttons to select Wipe Cache Partition, and confirm. This does not delete your data.
If That Didn't Work
- A recent software update can temporarily drain battery faster as it re-optimizes apps.
- Poor cell signal forces the radio to work harder and drains battery.
- An aging battery (after 2+ years) naturally holds less charge — check Battery Health in settings.
- Widgets on the home screen that update frequently use more battery than you would expect.
When to Call a Professional
If your phone is less than a year old and battery life is terrible even after these steps, contact Samsung support — it could be a defective battery covered under warranty. If the phone is over 2 years old, a battery replacement can bring it back to life.
