How to Optimize My Smartphone Battery To last Longer
1. Check which apps are draining your battery
In all versions of Android, hit Settings -> Device -> Battery or Settings -> Power -> Battery Use to see a list of all apps and how much battery power they're using. If an app you don't use often seems to take up a disproportionate amount of power, consider uninstalling it.
2. Uninstall apps
Delete apps you don't use from a single menu by heading to Settings -> Apps -> All. Tap on each app and hit Uninstall to remove it as well as any data it has created.
3. Never manually close apps
Despite the popularity of task-killer apps for Android, manually closing running apps doesn't help battery life, a myth recently debunked by both Apple and Google. In fact, closing an app can even very slightly damage battery life according to Android's SVP of Android, Chrome and Chrome OS, if the phone system requires it to run again (or when you open it again).
4. Remove unnecessary widgets from the home screen
Many Android apps, including social networks, weather apps and news apps, come with widgets that sit handily on the home screen for real-time updates. However, widgets are battery drainers due to their constant syncing with the mother-ship or power-sucking animations. If you don't need a permanent window into Twitter, or regular updates on the weather, remove the superfluous widget by pressing and holding it, then dragging it to the trash can icon.
5. Turn on Airplane Mode in low-signal areas
Smartphones use more power when trying to connect in low-signal areas. If you can't get a signal, turn on Airplane Mode by swiping down and tapping the Settings wheel. If your low-signal area is, say, an office or someone's home, you can turn on Wi-Fi (with Airplane Mode enabled) instead to stay connected. Then restart your cellular connection when you're in an area with better coverage.
On the flip side, disabling Wi-Fi may not always save battery life. Your phone uses less energy to connect to wireless than cellular networks, while Wi-Fi also helps phones determine location – handy for paring back the need for power-hungry GPS.
7. Turn off GPS when not in use
GPS is one of the heaviest drains on the battery – as you've probably noticed after using Google Maps to navigate your last road trip. When you're not actively using navigation, swipe down to access Quick Settings, and toggle it off. You'll be prompted to re-enable it when you use Maps.
Alternately, if you're using apps that require your location, you can head to Settings -> Location -> Mode and select “Battery saving” (where Wi-Fi and mobile networks are used to determine your location) over “High accuracy” (where GPS is also used).
8. Check app location tracking
Some apps track your location and therefore use more battery power than strictly necessary by accessing your GPS. At Settings -> Location you can see which apps recently requested your location, as well as how much (low/high) battery it took. For apps that seem to be demanding more than necessary, head into the apps and manually adjust the permissions individually.
9. Dim the screen – intelligently
If you're using Android 5.0 or newer, head to Settings -> Display and enable “automatic brightness”, which allows the phone to adapt the display based on the lighting where you are, ensuring the screen is never brighter than necessary.
But if your battery is in dire straits, manually dimming the screen is a good temporary fix until you can get to a charger. Pull down the notifications menu and drag the brightness slider to the very dimmest display level you're comfortable with.
10. Decrease screen timeout
You can save a little bit of battery power many times over by decreasing the length of time your phone remains idle before its display automatically goes dark. Head to Settings -> Display to adjust Screen timeout to, say, 10 seconds rather than an interval like 30 minutes (which you may have chosen if you were doing something like using the phone for a recipe).
11. Stop vibrating
If your phone is ringing, you don't need it to vibrate as well. Head to Settings > Sound and uncheck “Vibrate for calls”. To really get into battery miser mode, turn off haptic feedback, the handy little vibe when you press virtual keys, by going to Settings > Language and keyboard and unchecking “Vibration feedback”.
14. Keep weather updates local
Who doesn't love the weather widget that tells the time and the temperature in one handy, live-updating home screen box? If you've loaded yours up with cities where you've been vacationing, that widget could be contributing to heavy battery drain. Remove superfluous cities from your weather app by heading to Settings.
