Updating android phone
On Android 7, here you can also see how much “Cell standby” or “Mobile standby” is eating up – this is the amount of power your phone gobbles up while not being used.Delete apps you don't use from a single menu by heading to Settings All.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.
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.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.On the other hand, if notifications are necessary, prevent apps from waking the screen when they do send them through.
Head to Settings Display and select to turn off Ambient Display (which means no app notifications will cause the screen to wake).
Tap on each app and hit Uninstall to remove it as well as any data it has created. Apps with ads can eat up extra battery thanks to running ads (or if their ads are badly designed thereby hogging the juice), so if you find a favorite is using a lot of power, going for its premium ad-free version could help.
