Tech Tip: iPhone Battery Saving Tips

Share This:

iphoneIf you’re an iPhone user, sometimes you’ll notice that your battery life can be extremely poor. There are a few reasons for this and there are some settings you can check and some things you can turn off if you desperately need to squeeze a little more out of your battery.

Display Battery Life Percentage

While this won’t save any battery life (some might argue that it might add a little to the drain), it is handy to see your battery life percentage in your taskbar.

To do this, go to Settings > General > Usage > Turn on Battery Percentage.

Disable Siri Raise To Speak

This feature will use sensors in your phone so that if you hold it up to your ear, Siri will automatically activate. This is usually not needed since you can just long-press your home button to activate Siri.

To turn this off, go to Settings > General > Siri > Turn off Raise To Speak.

Disable LTE If It’s Not Needed

LTE on the iPhone 4S and iPhone 5 provides faster cellular internet where available. If you’re not in an LTE area, or if you don’t need it, you can turn it off to save battery life since it can use more battery than 3G/4G.

To disable this, go to Settings > General > Cellular > Turn off Enable LTE.

Disable Sending Of Diagnostic & Usage Information

This feature helps Apple improve their products and services. In other words, it sends anonymous information back to Apple at random times.

To disable this, go to Settings > General > About > Diagnostics & Usage > Select Don’t Send.

Brightness Settings

Under Settings > Brightness & Wallpaper, you have a couple of options. The first one is a slider for brightness. The lower you can set this, the better. Having a brighter backlight uses more power. You can also turn off Auto Brightness, but this won’t affect battery life much.

WiFi & Bluetooth

Under Settings, you’ll have options for both. If they’re not needed, it is recommended to turn them off.


Under Settings, you’ll have a menu for Notifications. Disable as many app notifications as possible and prevent them from pushing data to your phone unless its an important app.


The iPhone has an internet based messaging service built-into the phone that works when sending text messages to other iPhone users, this is called iMessage. I prefer to keep this enabled, but if you need to save battery life, go to Settings > Messages and turn off iMessage. This will force your phone to use SMS instead of iMessage.


If you don’t need push email (receiving emails as soon as they hit your Inbox), turn this off in your email settings for each account. Preferably, select the Manual setting. This will make it so that your phone will only check for new messages when you open the Mail app.

Kill Running Apps

Do a double click of the Home button and you’ll get a popup at the bottom of your screen that shows you a list of running programs. Long press on one of the apps and you’ll get they’ll all get a red circle with a negative sign where you can kill the app. Scroll through this list and kill any apps that might drain your battery in the background. After accessing Maps or anything that uses GPS, I almost always go into this task manager and kill it so it stops using my GPS immediately.

Location Settings

This can be the MOST important section to pay attention to and can make a HUGE improvement in your battery life.

Go to Settings > Privacy > Location Services. From here, there are a few things to check. If you don’t need GPS at all, turn off all Location Services.

If you want to keep GPS on, then go through the list of apps and turn GPS off on all apps that don’t need your GPS (or those that you don’t want to have access to your location). One thing to note is if any app has a purple triangle next to it, that means it is currently accessing your location. If it has a gray triangle, that means it has accessed your location within the last 24 hours.

The last thing to check under this menu is the System Services section. After going there, you’ll see a list of system services that use your location. Personally, I have everything turned off except for Cell Network Search. There’s been reports of a bug in the Setting Time Zone option, so you probably want to turn this off for sure. I noticed the Traffic one was using my location a lot while driving too and from work, even when I didn’t have my phone plugged in. Supposedly, this option sends anonymous traffic data back to Apple for use in Apple Maps.

Other Things To Notice

If you have severe battery drain after checking all of these settings, another thing to check is your charging cable. You might want to invest in another one because they can go bad or get shorts in them. So even if it shows your battery is fully charged, it may not be.
