One iPhone Setting That Can Help Improve Battery Life

Our iPhones can have so much going on that it can be difficult to keep track of everything. There are new apps to download, tons of features, and more to play around with. However, all that excitement can also mean that there's a lot going on in the background.

When apps and other iPhone features begin to run in the background frequently, keeping your feeds and content as up to date as possible, as imagined, that excess in activity can build up and cause some serious issues with battery life, therefore, you'll want to consider turning offa setting known as 'Background App Refresh,' a setting that can help prevent this from going overboard.

"Social media, banking apps, maps, and shopping apps are constantly refreshing data, checking locations, and updating content in the background," says Steven Athwal, tech pro and owner of The Big Phone Store. "They're using your phone's RAM and processing power, making the phone feel like a slug. Restricting background app refresh for the apps you don't need running all the time can give you an instant speed boost."

"The iPhone cannot perform effectively when it's hot, and its battery health has dropped, so these habits that are keeping it under persistent pressure are making it run slower over time," he adds. "Reducing this feature can help keep your phone moving fast."
