“Battery Life” is the amount of time your device runs before it needs to be recharged. “Battery Lifespan” is the amount of time your battery lasts before it needs to be replaced. Maximize both and you’ll get the most out of your Apple devices, no matter which ones you own.  Here are my recommendations for improving your iPhone battery:


Update to the latest software.

Apple software updates often include advanced energy-saving technologies, so always make sure your device is using the latest version of iOS.

How to update iOS  >


Optimize your settings.

There are three simple ways you can preserve battery life no matter how you use your device: adjust your Screen Brightness, set your Auto-Lock Timer, and use Wi-Fi.

1.  Dim the screen and turn on Auto-Brightness.

  • To dim, swipe up from the bottom of any screen to reveal the Control Center and drag the Brightness slider to the left.
  • Auto-Brightness adjusts your screen to lighting conditions automatically. To activate it, go to settings > Display & Brightness and set Auto-Brightness to On.

2.  Adjust your Auto-Lock Timer.

  •  Auto-Lock adjusts the amount of time your screen stays lite after no activity. To set the timer, go to settings > Display & Brightness and set Auto-Lock to 30 seconds, 1 Minute, or 2 Minutes.

3.  Choose Wi-Fi whenever possible.

When you use your device to access data, a Wi-Fi connection uses less power than a cellular network so keep Wi-Fi on at all times.  There are two ways to turn on Wi-Fi. In addition, if you see your in an area with little to no data coverage – stop your device from searching for a signal by either toggling Airplane mode On or turning Cellular Off.

  • Swipe up to open Control Center, tap the Wi-Fi icon, and log in to a Wi-Fi network.
  • Go to Settings > Wi-Fi to access a Wi-Fi network.

Enable low power mode.

Introduced with iOS 9, Low Power Mode is an easy way to extend the battery life of your iPhone when it starts to get low. Your iPhone lets you know when your battery level goes down to 20%, and again at 10%, and lets you turn on Low Power Mode with one tap. Or you can enable it by going to Settings > Battery.  Low power mode reduced display brightness, optimizes device performance, and minimizes system animations. Apps including mail will not be disabled. You can still use key functions like making and receiving phone calls, emails, messages, and more. And when your phone charges up again, Low Power Mode automatically switches off.


Background activity & app refresh.

This indicates that the battery was used by the app while it was in the background – or while you were using another app.

  • To improve battery life, you can turn off the feature that allows apps to refresh in the background. Go to Settings > General > Background App Refresh and set the switch to Off.
  • If the Mail app lists Background Activity, you can choose to fetch data manually or increase the fetch interval. Go to Settings > Mail, Contacts, Calendars > Fetch New Data.

Location services and background location.

This indicates the app is using location services. You can optimize your battery life by turning off Location Services for individual apps. Turn off in Settings > Privacy > Location Services.

In location services, you can see each app listed with its permission settings. Apps that recently used location services have an indicator next to the on/off switch.


Home and lock screen display settings.

This indicates the Home Screen or Lock Screen was displayed on your device.  For example, the display was awakened by pressing the Home button or by a notification.  If an app frequently wakes your display with notifications, you can turn off push notifications for the app in Settings > Notifications. Tap App and set Allow Notifications to Off.

And there you have it!  Make these simple changes one-by-one to update your settings and I’m certain you will see improved battery life. If you think your battery lifespan has reached it’s final days see how to get it replaced below.

Purchasing an iPhone? Here’s How You Can Pay For It

A few years ago carriers stopped offering a subsidy (usually a few hundred dollars off) when you agreed to sign a new two-year contract with them. When the carriers moved to the monthly payment plans, Apple got in the game too. Now you have multiple options for how you want to finance this $$$$ new iPhone. With multiple options comes multiple questions…
