Tips Preserve iPhone Battery

Let’s imagine that you need to make an emergency call from your iPhone and your battery is critically low. Unfortunately, you don’t have a charging cable or a power bank to charge your phone. What will you do? Here are some tips to save iPhone battery during an emergency when there is no alternate source of power.

1. Turn OFF Bluetooth and Wi-Fi

Can Bluetooth or Wi-Fi drain your battery? Of course, they consume more power, if you are using any of these communications on the iPhone actively. However, it won’t drain your battery much when they are only turned ON but kept idle without any usage. Still, you need to turn them off, if your battery is critically low and you need to keep your iPhone live at least for another few minutes or so. You can turn Bluetooth and Wi-Fi OFF either from the Control Center or by navigating to Settings->Bluetooth and Settings->Wi-Fi on your device.

2. Disable Location Services

iPhone apps like Maps, Camera are using Location Services to get your current location while using the app. However, if your device is about to die, then you should turn off the location sharing/services immediately. This will avoid draining your battery and save battery use for emergency use. The location services consume a lot of power as it makes use of GPS, Wi-Fi, Bluetooth to find out your current location.

Navigate to Settings->Privacy. Next, tap the position of the switch titled Location Services to the left. Then, tap Turn Off button on the confirmation pop up. Once your iPhone is recharged, you can turn on the Location services again.

3. Turn ON Low Power Mode

When your battery level reaches 20%, iOS will display a pop up with two options Low Power Mode and Close. You can use that option to activate Low Power Mode on your iPhone.

You can also manually turn ON the Low Power Mode from Settings->Battery in advance before reaching the 20% threshold. The device will automatically quit from Battery Savings Mode after charging the battery enough. The Low Power Mode helps to reduce your battery usage by restricting a lot of features like background refresh, email fetch, Siri and more.

4. Disable Mail Fetch

In iOS, there are two options to check for new emails: Fetch and Push. In Fetch, your phone will connect to the internet, checks for new emails and downloads them on your device. If the fetch time interval is set to Every 15 minutes, then your device will check for new emails every 15 minutes.

iPhone Disable Mail Fetch

However, fetching frequently will quickly drain your battery. Hence, it is highly recommended to set either a long timeout (1 hour) or manual option for the mail fetch. Navigate to Settings->Passwords & Accounts->Fetch New Data. Under the section titled FETCH, modify the fetch schedule to Manually or Hourly. In case it is set to Manually, then your iOS will check for new email only when you open your email client. You can use this option if you would like to save your iPhone battery for emergency.

If your email client supports Push feature, then you can make use of that instead of Fetch. Unlike Fetch, Push doesn’t check emails at regular intervals as that job is done by your email server. Hence, your device won’t consume a lot of battery. Push feature is supported by Gmail, iCloud mail, Yahoo Mail and more.

5. Check If Vibration is Turned OFF

A lot of people make the mistake of turning on both vibration and ringing sound on their phones. If you can hear your phone ringing sound, there is no need for vibration. Right? Also, keeping your iPhone in vibration mode consumes more power.
