Why Battery Health Matters

Battery health determines how efficiently your phone stores and delivers power. A well-maintained battery ensures:

  • Longer daily runtime

  • Slower degradation over time

  • Reduced overheating

  • Consistent charging performance

Without proper care, your Samsung S25 battery may start draining faster, charging slower, or shutting down unexpectedly — all signs of battery wear.


Step 1: Use Samsung’s Battery Protection Features

The Galaxy S25 includes built-in protection options to preserve long-term battery health.

  1. Go to SettingsBattery and Device CareBattery.

  2. Tap More Battery SettingsProtect Battery.

  3. Toggle Protect Battery on.

This feature limits charging to 85% instead of 100%, reducing stress on the battery and extending its lifespan — especially helpful for overnight charging.


Step 2: Avoid Extreme Temperatures

Batteries are sensitive to temperature.

  • Avoid heat: Do not use your phone while charging or leave it in hot environments (like in direct sunlight or in a car).

  • Avoid cold: Extremely low temperatures can reduce capacity temporarily.

Keeping your Samsung S25 between 15°C–35°C (59°F–95°F) helps maintain optimal performance.


Step 3: Enable Adaptive Battery

Samsung’s Adaptive Battery intelligently learns your usage patterns and prioritizes power for frequently used apps.

  1. Open SettingsBattery and Device CareBattery.

  2. Tap Background Usage Limits.

  3. Enable Adaptive Battery and Put Unused Apps to Sleep.

This minimizes background drain and ensures only essential apps consume power.


Step 4: Optimize Charging Habits

Charging behavior significantly affects battery lifespan. OnePlus recommends:

  • Use the original Samsung charger and cable or certified fast chargers.

  • Avoid letting the battery drop below 20% regularly.

  • Disconnect the charger once it reaches around 85–90% (or use Battery Protect).

  • If you charge overnight, enable Protect Battery as mentioned earlier.

Smart charging prevents battery stress and keeps capacity stable over time.


Step 5: Manage Background Apps

Background apps silently consume energy even when not in use.

  1. Go to SettingsBattery and Device CareBatteryBackground Usage Limits.

  2. Tap Sleeping Apps and add any apps you rarely use.

  3. Optionally enable Auto Optimization to close unused apps daily.

This keeps your Galaxy S25 running efficiently without unnecessary drain.


Step 6: Lower Display and Connectivity Drain

  • Reduce screen brightness or enable Adaptive Brightness.

  • Turn off Always On Display when not needed: Settings → Lock Screen → Always On Display → Off.

  • Disable 5G, Bluetooth, or Wi-Fi when not in use.

These small tweaks can extend daily battery life by several hours.


Step 7: Keep Software Updated

Software updates often include battery optimization improvements.
Navigate to SettingsSoftware UpdateDownload and Install to ensure your phone runs the latest version.

Regular updates also fix bugs that may cause unnecessary battery drain.


Final Thoughts

Maintaining good battery health on your Samsung Galaxy S25 doesn’t require complex steps — just consistent habits and smart use of built-in features. By following OnePlus’ guide, you can reduce wear, improve daily endurance, and ensure your device performs like new for years. Remember, a healthy battery equals a reliable smartphone experience.
