Maintaining a strong iPhone battery takes a little work and vigilance. Namely, it requires you to be vigilant about the apps that you use and aware of which consume the most battery power (for example: anything with GPS). It’s also a smart idea to stay on top of your settings. Some of the settings on your phone provide you a better overall iPhone experience — they may update apps faster so that you never have to wait for fresh content or even make your phone background look more chic. But if they’re eating into your battery power in a major way, they aren’t worth it.
Tech Expert Marcus Clarke points out three settings that he says you should always have turned off on your iPhone if you want your battery to last longer. If you’re experiencing fast battery drainage, check and make sure you have these settings turned off.
Background App Refresh
Firstly, ‘Background App Refresh’ is a feature that allows apps to update content in the background, Clarke explains. “Disabling this for apps you don’t use often can conserve a significant amount of battery as it reduces the workload on your device,” he says. “To do this, navigate to Settings > General > Background App Refresh, and turn it off for unnecessary apps.”
Screen Brightness
The next setting to turn your attention to is Screen Brightness — a too-bright screen is a major culprit behind battery drainage. “You can reduce your screen brightness manually or enable auto-brightness,” Clarke says. “This setting adapts your screen to lighting conditions thus saving battery life. You can find this in Settings > Display & Brightness.”
Dynamic Wallpapers
And thirdly, 'Dynamic Wallpapers' and 'Motion' (parallax effect) can also consume more power, Clarke warns. “Turning off these visual effects can contribute to battery saving. Go to Settings > Accessibility > Motion and then toggle on 'Reduce Motion,’ Clarke says. “In essence, by being judicious about your iPhone settings, you can optimize battery life significantly. Always remember, the key is to limit non-essential processes and features.”
