Save Your Battery: Turn Off Bluetooth, Wi-Fi, and LTE When You Aren’t Using It [iOS Tips]

IMG_1570

Several technologies on your iPhone, including Bluetooth, Wi-Fi, and cellular data, are made to continually check for signal when you’re out and about. Continual checking requires power, which comes from your iPhone (or iPad, or iPod touch) battery.

It makes sense, then, that turning these different wireless features off when you don’t need them can help your battery last a little longer. Here’s how to do just that.

Bluetooth can be found in your Settings app. Tap it to launch, and then tap again on Bluetooth. Toggle the switch to OFF.

Tap the Settings back arrow and then tap on the Wi-Fi area. Again, tap the toggle switch to OFF. Note that if you’re using your iPhone for location-based services, like Maps and the like, the accuracy will be better with Wi-Fi set to ON.

Tap that Settings back arrow once more, then tap on General. Tap on Cellular on the next page, and go ahead and turn Cellular Data to OFF. You’ll be able to make phone calls, but not use the internet via your iPhone’s cell data connection.

You can also turn all of this off with a quick trip to the Airplane mode. Tap on Settings, then hit the toggle for Airplane Mode to OFF. Now all your send/receive transmissions will be shut OFF. If you want to use Wi-Fi on the plane, for example, you can tap Wi-Fi and turn it to ON, without enabling the other no-no services.

    Correct me if I’m wrong but isn’t the amount of battery drain from leaving Bluetooth on extremely minuscule? I thought one of the features with the newest Bluetooth version is that it uses extremely low power.

    No, no an no. If any of these is draining your battery substantially, it’s just a symptom of a bigger problem. The power used by leaving the radios on is negligible under normal circumstances. The only thing that uses substantial power searching is 3G/LTE when it’s out of range or on the fringe. Otherwise, wifi and Bluetooth use allst nothing when inactive.
