Whenever your iPhone dips down to 20 percent, it provides a helpful service: it sends you a low battery alert warning so that you can better manage your phone time and conserve battery until you’re in reach of a charger.
The worst mistake you can make when you receive this low battery alert is ignoring it. If you continue to use your phone’s apps that way you were previously using them — such as spending hours on Facebook or running a navigation app like Waze without charging your phone at the same time — you will drain the battery super fast.
The first step you should take is to stop running apps that are known culprits when it comes to battery drainage. These apps include Facebook, Instagram, Twitter, navigation apps, and streaming apps like Netflix and Spotify. All of these apps put more stress on your phone and require it to work a lot harder than it should be working when it’s down to its last leg in terms of battery power.
But, even more importantly, you should always turn on Low Power Mode the minute you realize your phone is low on battery. When your phone is in this mode, it stops or reduces mail fetch, background app refresh, automatic downloads, and visual effects that eat away at your battery, according to Techlicious.
Switching over to Low Power Mode is simple. Go to Settings > Battery and toggle to Low Power Mode. Your phone won’t run at the same capacity until you power it up again, but this mode will at least save your device from a quick and painful death (when you still need it to be functional).
The worst mistake you can make when you discover your phone is low on battery is to do nothing at all. Taking these simple steps will save you battery power until you can charge your phone again.
