Best jugak artikel ni. Beberapa tips pernah aku buat ketika bateri aku kritikal. Cuba jangan tak cuba.
- Beware of location servicesMany apps on iPhone and Android use "location services" to, say, tag status updates with GPS data ("We're at Disney World!") or find good deals in your immediate area. This can reduce battery life, so always keep track of it.
- Use a black (or very dark) wallpaperIf your phone uses an AMOLED display—many popular Android devices do —each pixel on the screen takes a little bit of power to "light up." As such, the more black pixels you can get on your screen, the better. Set a dark wallpaper as your default, and try using dark themes on apps when possible.
- Use 'Airplane Mode'Your iPhone or Android device will always try to connect to a cellular network when possible, which can put a strain on your battery if you're in an area with limited (or no) service. Switching on Airplane Mode in Settings will stop this from happening—just know that you won't be able to make or receive calls while it's toggled on.
- Clear out appsEven if you're not using an app, it can run in the background and sap battery life from your smartphone. Android devices allow you to "multitask" with apps running behind the scenes—to close them quickly, go to "Applications" within your settings, then tap either the "Manage Applications" or "Running" option. Go down the list and tap any you're not using, then "Force Stop" or "Stop."
Apps don't "multitask" on iPhones in the same way they do on Android phones, but the principle's the same: Unused apps slowly but surely eat away at your battery life. Quickly push the home button on the bottom of your iPhone twice to bring up a row of apps currently open on your device, then hold your finger on one until they all start jiggling: Simply tap the red "minus" icon to close the apps completely.
- Lower the brightnessObvious but easy to neglect: The brighter your screen, the more battery it's eating. Head over to your settings and turn down the lights to keep your phone running longer.
- Turn wi-fi offAnother simple-but-forgettable tip: If you're not using your smartphone to connect to wireless internet, switch the wi-fi settings to "off." This will stop your phone from sniffing out networks—even when you think it's not—thereby saving resources.
- Keep it coolIf your phone's Lithium-Ion battery gets too hot, it'll discharge its energy faster, and could even degrade the battery's maximum life over time. Don't carry it in your pocket if you can avoid it (especially if your pants are tight), and never leave your device sitting in direct sunlight or in a toasty car.
