10 Ways to Get More Battery Life From Your Smartphone
Few things are more frustrating than watching your phone hit 10% at 2pm. Battery anxiety is real — but most people are unknowingly draining their battery faster than necessary. These tips apply to both iPhone and Android and require no technical expertise.
1. Lower Your Screen Brightness
The display is the single biggest battery drain on any smartphone. Dropping your brightness from 100% to 60–70% can meaningfully extend screen-on time. Enable auto-brightness to let the phone adjust based on ambient light — it's usually more efficient than manually managing it.
2. Use Dark Mode
On phones with OLED or AMOLED displays (most modern flagships), dark mode genuinely saves battery because black pixels are literally turned off. Enable dark mode in your system settings and in individual apps for a passive power boost throughout the day.
3. Shorten Screen Timeout
Your screen staying on for 2 minutes after you put the phone down wastes a surprising amount of energy over a day. Set your auto-lock/screen timeout to 30 seconds or 1 minute. You'll barely notice it, but your battery will.
4. Manage Location Services
GPS is a major battery consumer. Audit which apps have "Always On" location access — most don't need it. Set apps to "While Using" or "Never" where appropriate. On Android: Settings → Location → App permissions. On iPhone: Settings → Privacy → Location Services.
5. Turn Off Wi-Fi and Bluetooth When Not in Use
If you're out and about without known Wi-Fi networks, disable Wi-Fi so your phone stops scanning constantly. Same with Bluetooth if you're not using headphones or a watch. Both can be toggled quickly from the Control Center or Quick Settings panel.
6. Disable Background App Refresh
Apps refresh in the background to show updated content when you open them. This convenience has a battery cost. Disable it for apps you don't check frequently.
- iPhone: Settings → General → Background App Refresh
- Android: Settings → Apps → select app → Battery → Restrict background activity
7. Identify Battery-Hungry Apps
Both iOS and Android show you which apps consume the most battery. Check this weekly and investigate any app using an abnormally high percentage — it may have a bug or need a settings adjustment.
- iPhone: Settings → Battery
- Android: Settings → Battery → Battery Usage
8. Enable Low Power / Battery Saver Mode Earlier
Don't wait until 10% to enable battery saver. Turning it on at 30–40% when you know you won't be near a charger can extend your phone's life by hours. It throttles background activity, reduces visual effects, and dims the display slightly.
9. Avoid Extreme Temperatures
Lithium-ion batteries degrade faster in extreme heat or cold. Don't leave your phone in a hot car or charge it in direct sunlight. This tip is about long-term battery health, not just today's charge level.
10. Optimize Charging Habits
Keeping your battery between 20–80% charge is gentler on battery health than regular deep discharge and full charge cycles. Many phones now offer "optimized charging" features that slow charging above 80% overnight — enable this if your phone offers it.
Quick Reference
| Tip | Impact | Effort |
|---|---|---|
| Lower brightness | High | Low |
| Dark mode (OLED) | Medium | Low |
| Restrict location services | High | Medium |
| Background app refresh off | Medium | Low |
| Battery saver mode early | High | Low |
Small changes compound quickly. Applying even half of these tips can meaningfully change your daily battery experience without making your phone feel crippled.
