- Use Airplane Mode during flights or weak signal areas
- Turn off background sync and auto-updates
- Lower screen brightness or turn on reading mode
Does Dark Mode Save Battery on Smartphones?
Yes, especially on OLED or AMOLED screens (used in many Samsung and Android phones). Dark Mode turns off individual pixels to display black, resulting in lower power consumption. Even on LCD screens, Dark Mode helps reduce eye strain and may slightly improve battery performance.
Impact of Background Apps on Battery Consumption
Background apps can drain your battery without you knowing. Apps like Facebook, Instagram, and Google Maps often update data or track location in the background. Here’s how to manage them:
- Go to settings and restrict background activity
- Use built-in tools like App Battery Usage to monitor power-hungry apps
- Force stop unused apps when not needed
How to Calibrate Smartphone Battery for Optimal Performance
Battery calibration helps your phone give accurate battery percentage readings:
- Charge your phone to 100% and leave it on the charger for another hour.
- Use the phone normally until it reaches 0% and shuts off.
- Leave it turned off for a few hours.
- Charge it back to 100% without turning it on.
- Repeat every 1-2 months for better battery accuracy.
Quick Checklist to Maximize Battery Health
- Avoid full discharges (0%) and overcharging (100%)
- Use manufacturer-approved chargers
- Avoid using phone while charging
- Uninstall unused or bloatware apps
- Monitor battery usage regularly
