How to Make Your Phone Battery Last Longer: 15 Easy Tips

Nothing is more annoying than a phone that dies when you need it most. The good news is that a few simple settings and habits can help your battery last longer through the day and stay healthy over time. Menu names differ between phone brands and software versions, but you can usually find these options in your phone's Settings or by using the search box inside Settings.

Part 1: Save battery during the day

1. Lower your screen brightness

The screen is one of the biggest battery users. Lower the brightness when you do not need it very bright, or use automatic brightness so the phone adjusts for you.

2. Shorten the screen timeout

Set the screen to turn off after 30 seconds or one minute of no use, instead of several minutes. This stops the display from staying on when you put the phone down.

3. Use dark mode if your phone has an OLED screen

On phones with OLED or AMOLED screens, dark backgrounds can use less power because dark pixels need less light. On other screen types, the difference may be small. Dark mode is also easier on the eyes at night.

4. Turn on battery saver mode

Most phones have a battery saver or power saving mode that reduces background activity and some features. Use it when your battery is getting low or when you know you will be away from a charger for a long time.

5. Close or limit battery-hungry apps

Open the battery section in Settings to see which apps use the most power. If an app uses a lot but you rarely need it, limit its background activity or uninstall it. Be careful with apps that run constantly, such as some social media, video and game apps.

6. Turn off background refresh and unnecessary notifications

Many apps keep updating in the background. Turn off background refresh for apps you do not need to update all the time, and reduce notifications that are not important. This saves both battery and attention.

7. Switch off features you are not using

Bluetooth, Wi-Fi, location services, NFC and mobile hotspot all use power when active. Turn them off when you do not need them. Use location access only while using the app for apps that do not need it all the time.

8. Be smart about your network

A weak mobile signal makes the phone work harder and drain the battery. If you are in an area with poor reception for a long time, use Wi-Fi if available, or switch on airplane mode when you do not need calls or data.

9. Reduce heavy tasks

Gaming, long video streaming at high quality, GPS navigation and using the camera for a long time all use more power. Lower the video quality, limit game time on low battery, and download maps or videos in advance when possible.

Part 2: Charge in a healthy way

10. Avoid extreme heat

Heat is bad for batteries. Do not leave your phone in a hot car or in direct sunlight, and take off a thick case if the phone gets very warm while charging. Gaming while charging can also heat the phone.

11. You do not need to wait until 0%

Modern phone batteries do not need to be drained completely before charging. Many manufacturers suggest that partial charges are fine, and that frequently letting the battery drop to zero is not ideal. Check your phone brand's own advice for the best habits.

12. Use the right charger

Use the original charger or a good-quality one from a trusted brand that supports your phone. Very cheap, unbranded chargers and cables can be unsafe and may damage the battery or even cause hazards.

13. Use optimized or adaptive charging if available

Many phones have features that learn your routine and slow charging overnight, so the battery does not sit at 100% for hours. If your phone has such a setting, turn it on and read what it does.

14. Keep your software updated

Updates often include battery and performance improvements. Install updates from official sources, and update your apps regularly because old app versions can use more power.

15. Restart your phone from time to time

A restart can close stuck processes that drain battery in the background. If a certain app or process keeps draining power, try updating, reinstalling or removing it.

Signs that your battery needs attention

It drains very fast even with normal use.

The phone shuts down suddenly at a high percentage.

The phone gets very hot without heavy use.

The battery looks swollen or the case is bulging. Stop using the phone immediately and take it to an authorized service center, because a swollen battery can be dangerous.

Many phones show a battery health or battery usage page in the settings. If your battery has worn out after years of use, replacing it at an authorized service provider may be cheaper than buying a new phone.

Common mistakes to avoid

Using task killer apps. Constantly closing and reopening apps can use more power than leaving them alone.

Buying cheap fake batteries or chargers. They can be unsafe.

Charging under a pillow or on a bed. Heat can build up. Charge on a hard, open surface.

Ignoring app updates. Old apps can be less efficient.
