Please check these 7 easy steps to optimize your device's battery life:
1) Always make sure your device is using the latest OS.
Device makers update software for their devices periodically, and these updates often include increases in battery efficiency. You can get the latest version of iOS by going into the Settings App > General > Software Update. You can get the latest version of Android by going to Settings > System > About phone > System updates.
2) Keep WiFi on at all times.
It may seem counterintuitive, but even when you aren't connected to a Wi-Fi hotspot, Device Makers have designed their devices to use hotspot proximity (and you likely pass thousands of them a day) to register location information. They did this because Wi-Fi is actually far more efficient on batteries than other location sources like GPS while at the same time providing more data points for calculating location more accurately.
3) Adjust screen brightness.
Dimming the screen or turning on Auto-Brightness will help with battery life immensely.
To dim manually on iOS, go to Settings > Wallpapers & Brightness and drag the slider to the left. To activate Auto-Brightness on iOS, go to Settings > Wallpapers & Brightness and set Auto-Brightness to On.
To dim manually on Android, pull down from the top of the screen to expose the Control Panel. Adjust the top slider as appropriate.
4) Fetch new email less frequently.
Fetching email more often uses more power. To fetch email less often on iOS, go to Settings > Mail, Contacts, Calendars > Fetch New Data and tap Hourly.
Note: This global setting applies to all applications that do not support push services.
5) Turn off push notifications for unused applications.
To disable push notifications, go to Settings > Notification Center, choose the app you want to disable. Then, change alert style to None, turn Badge App icon off, and turn Sounds off. Note: No push notifications will be received for the application in question unless you reverse this process, but new data will always be received for the app when you open it.
6) Minimize use of location services.
Running extra apps that use location services can reduce battery life. Please make sure that you are only giving this functionality to the applications you want to give it to.
You can see which applications have recently used location services on iOS by going to Settings > Privacy > Location Services. You can see which applications have recently used location services on Android by going to Settings > Personal > Location.
Apps that recently used your location have an indicator next to the on/off switch. If you do not expect or want a particular app to use location services, you can disable it by toggling the switch to Off.
Note: MileIQ requires use of location services to function properly, so leave it on to ensure MileIQ can detect drives for you.
7) Turn on Airplane mode in low coverage or no coverage areas.
Your device with cellular capabilities will always try to maintain a connection with a cellular network, which may use more power in low coverage or no coverage areas. In these situations, you can turn on Airplane mode to increase battery life.
To turn on Airplane mode on iOS, swipe up from the bottom of your device to open Control Center. Then, tap the Airplane mode icon. Alternatively, you can go to Settings and set Airplane mode to On.
To turn on Airplane mode on Android, swipe down from the top of your device to open Control Panel. Then, tap on the Airplane mode icon. Alternatively, you can toggle Airplane mode from Settings > More.
Note: No calls can be made or received with Airplane mode on
