A better, more efficient iPhone battery starts with knowing which settings you can make work in your favor — sometimes that means enabling them, and other times it means disabling them.
Some settings can truly run your battery low and cause you to run looking for a charger. Many of us have several battery-sucking settings on at the same time, or we aren’t taking advantage of settings that can save us battery power and conserve it until we have time to charge our devices. Here are three iPhone settings you should either have switched on or turned off for a longer-lasting battery.
1. Auto-Lock
When iPhone Auto-Lock is enabled, a signal is sent to your phone’s screen to turn off after a certain period of inactivity. This helps conserve battery power and keeps your phone from performing unnecessary background activities. Go to Settings > Display & Brightness > Auto-Lock. Choose a time: 30 seconds, 1 minute, 2 minutes, etc. The shorter the time, the more battery you’ll save.

2. Background App Refresh
Background App Refresh is one setting you’ll want to disable, if not for all apps, then for most of them. This setting prompts your phone to continually run processes in the background that update apps so that they are completely up-to-date at all times. The problem with this convenience is that it is taxing on your battery. To disable it for certain apps, or all apps, go to Settings > General > Background App Refresh.

3. Low Power Mode
If you’re far from a charger when your iPhone battery drips below 20 percent, turn on Low Power Mode to conserve battery power. This setting will temporarily reduce power usage and do things like lower screen brightness, reduce mail fetch frequency, and disable visual effects. But these are minor inconveniences for the benefit of not watching your phone die when you still need it to function.
