Managing Battery Life on the iPhone X

By Edward C. Baig, Bob LeVitus

There are a few ways you can extend the battery life on your iPhone X. First and foremost: If you’re not using a 3G, 4G, or Wi-Fi network or a Bluetooth device (such as a headset or car kit), consider turning off the features you don’t need in Control Center. Switching the iPhone’s functions on and off has never been easier or faster, and doing so could mean the difference between running out of juice and being able to make that important call later in the day.

Better still, enable airplane mode (also in Control Center) to turn off all your iPhone’s radios. Airplane mode disables cellular, Wi-Fi, Bluetooth, Location Services, and push notifications all at once. You can’t make or receive phone calls in airplane mode, nor do anything that requires network access. But if you’re going to be off the grid for any length of time, like on a long flight, your battery will last a lot longer if you use Control Center or the Settings app to enable airplane mode until you return to civilization.

Speaking of Control Center, use its brightness slider to reduce brightness manually whenever possible and activate auto-brightness. This setting enables your iPhone to adjust its screen brightness based on current lighting conditions, which can be easier on your battery. From the Home screen, tap Settings → Display & Brightness, and then tap the On/Off switch, if necessary, to turn it on.

If your battery is low and airplane mode and auto-brightness aren’t appropriate solutions, try low power mode. Just tap Settings → Battery and then tap the Low Power Mode on/off switch. With this feature enabled, mail fetch, background app refresh, automatic downloads, and some visual effects are disabled to reduce power consumption.

And while you’re on the Battery page in Settings, scroll down and you’ll see which apps used the battery in the past 24 hours. Tap the little clock icon on the right to see the precise number of minutes (or hours) each app was active on the screen and in the background. This representation of which apps are using the most battery power is probably the most accurate, so don’t forget to visit Settings → Battery every so often to take a peek.

Turning off Location Services (tap Settings → Privacy → Location Services, and then tap the On/Off switch) can save tons of battery, so consider turning it off until you need it. Many apps that use Location Services will offer to enable it for you if you launch those apps while Location Services is turned off.

Believe it or not, disabling EQ for audio also conserves battery life. EQ (equalization) may make music sound a bit better, but it also uses more processing power, and that means it uses more of your battery. If you’ve added EQ to tracks in iTunes using the Track Info window, and you want to retain the EQ from iTunes, set the EQ on your iPhone to flat. Because you’re not turning off EQ, your battery life will be slightly worse but your songs will sound just the way you expect them to sound. Either way, to alter your EQ settings from the Home screen, tap Settings → Music → EQ.

Finally, if you use a carrying case, charging the iPhone while it’s in that case may generate more heat than is healthy. Overheating is bad for both battery capacity and battery life (and bad for your iPhone in general). So if your iPhone feels warmer than usual while charging, you might want to take it out of its case before you charge it, if at all possible.

Apple says a properly maintained iPhone battery will retain up to 80 percent of its original capacity after 400 full charge and discharge cycles. Your one-year limited warranty includes the replacement of a defective battery. Coverage jumps to two years with the AppleCare and AppleCare+ Protection Plans. If your battery isn’t maintaining a charge the way it used to and your iPhone is still under warranty, you might want to take it in for (free) replacement.

If your iPhone is out of warranty, Apple will replace the battery for $79 plus $6.95 shipping and local tax and will also dispose of your old battery in an environmentally friendly manner.
