Android devices always have an issue with short battery life, but that’s only if you stick with its default settings. You should make few adjustments to give your phone or tablet a battery boost.
Disable location reporting and history
GPS will take too much batter, as it harnesses data from the phone’s GPS chip, cell phone towers, and Wi-Fi hotspots to find your location. The more a phone surveys your location, the more battery it uses. And that goes beyond just Google Maps. Location reporting and location history are two GPS-based services with somewhat unclear motives. According to a Google Help page, the services can be used in conjunction with any other Google Apps, and may be used to improve your experience.
You can probably live without them, so disable these two features by going to Settings > Location > Google Location Reporting.
Disable Google Now cards
Now is an unmatched personal assistant, but some of its services — which come in the form of informational “cards” — are tireless battery drains.
For example, a card titled “Nearby places” shows you nearby attractions when you travel to a place that Google recognizes is out of your usual routine.
To disable cards, go to Google Now, then scroll down to the very bottom, and tap the magic wand. Here, you can pick the cards you actually need. As a general guide, the GPS-reliant cards will demand the most battery, so disable cards like “Travel time” and “Nearby places” to see a battery boost.
Wi-Fi scanning
Wi-Fi is left enabled uses more energy. However, on Android, even when Wi-Fi is disabled, a phone could still be searching for networks. To make sure this isn’t happening, head to Wi-Fi settings > Advanced. Here, uncheck the option for Wi-Fi scanning.
Use the battery tool
If you’re unsure how energy-demanding an app is, or you’re wondering why your battery is draining so quickly, use the Battery tool. The feature shows you which apps use the most battery, with the top two items almost always being Screen and Wi-Fi.
