10. Turn off WiFi
Keeping WiFi on when you’re outside of WiFi range, will cause your battery to drain faster.
On an iPhone, go to Settings > WiFi and turn WiFi off.
9. Turn off location services
Lots of apps want to know our location to provide a better user experience. However having that little blue dot constantly knowing where we are takes a lot of data and battery power.
On an iPhone, go to Settings > Privacy and turn off location services, or select which apps you do and don’t want to use location services.
8. Turn down brightness / Turn on Auto-brightness
A super crisp and bright screen is great and all, but having a phone with battery life is better.
On an iPhone, go to Settings > Wallpaper & Brightness and lower the brightness level OR turn on Auto-brightness
7. Turn off Bluetooth
Same deal as WiFi. Kill it when not in use.
On an iPhone, go to Settings > Bluetooth and turn Bluetooth off.
6. Upgrade to the latest firmware release
There’s some very smart people working at the likes of Apple, Samsung, HTC, etc, and they’re constantly working out improvements to conserve your phone’s battery.
If you haven’t updated your phone’s operating system for a while, make it a priority.
5. Turn off Background App Refresh
If you’ve got Background App Refresh on, your apps will constantly refresh their content. To Apple own admission: “turning off apps may help preserve battery life”.
On an iPhone, go to Settings > General > Background App Refresh and turn off Background App Refresh, or select which apps to turn off.
4. Turn off Dynamic Backgrounds
Do you have a funky little moving bubble feature as your screen’s desktop or lock screen? Cute, but bad idea. Turn it off to same juice.
On an iPhone, go to Settings > Wallpaper & Brightness > Choose Wallpaper and select a still image.
3. Don’t auto update Apps
It’s now default for phones to automatically downloaded new versions of Apps released by the App developer. Cool, but not if you’re in the red zone.
On an iPhone, go to Settings > iTunes & App Store and turn off Updates.
2. Set auto lock to the shortest possible time
This is a simple one, but highly effective. The more time you phone is on when you’re not using it, the shorter the battery life will be, so set the lock screen to activate as quickly as possible.
On an iPhone, go to Settings > General > Auto-lock and set to 1 minute.
…and finally, the biggest culprit of them all!
1. TURN OFF PUSH FOR EMAIL & SET FETCH TO MANUALLY
If your phone is set to ‘Push’ mail, it is constantly asking the mail server in the cloud if there’s any changes, ie new emails. This actually happens every second, smashing the battery level. Madness!
It’s nice to be alerted as soon as you receive a new email – we agree – but that’s nothing compared to the pain of having a phone with a dead battery.
On an iPhone, go to Settings > Mail, Contacts & Calendars > Fetch New Data and turn Push off. For maximum battery savings, set Fetch to manually.
If you’re on an exchange server, doing this one thing will see your battery life will soar!
However, if you’ve set Fetch to Manually, you’ll need to go into your mail app before it will retrieve new emails. A small price to pay, in our humble opinion.
