Apple's IPhone With Best Battery Life Is IPhone 8 Plus, Not IPhone X

If you want the iPhone with the longest battery life, you don't necessarily want the iPhone X, Apple's highest-end iPhone. 999 iPhone X is clearly Apple's flagship, it doesn't sport flagship battery life. Instead, look to the less expensive iPhone 8 Plus for Apple's longest-lasting battery. This is largely because Apple can fit a bigger battery into the Plus-sized dimensions of the phone. As you can see, the iPhone 8 Plus manages an extra hour of internet use and video playback, according to Apple's testing. That's not to say the iPhone X has bad battery life. There haven't been any independent tests yet, and Apple says it lasts significantly longer than the iPhone 7 while being roughly the same size. So if you're looking for the longest battery life possible, don't simply go out and buy Apple's most expensive and most advanced iPhone.

3. Watch your signal strength indicator. If you spend a lot of time in areas with poor reception, your iPhone will continually search for a stronger signal. This drains the battery much faster. I've left my iPhone untouched on my desk, where there's a particularly poor signal, and watched the battery drain by almost half over the course of a workday.

4. Check for email manually. Push email is another perennial battery drain, albeit less so. Fetch New Data, toggle Push at the top to Off, and then set Fetch to Manually. 5. Turn off Location Services and Frequent Locations. This is a big one, as hitting the iPhone's GPS constantly can blaze through your battery. Location Services to cap this behavior. You can tap the On/Off slider next to Location Services to turn all of them off, but you can also disable these services on an individual app basis below.

Many apps don't need to know your whereabouts, especially in the background. Another one to be aware of is Frequent Locations, a relatively new feature that tracks where you are most often in order for apps to send you targeted ads; aside from being annoying, it also drains battery. From Location Services, scroll down to Frequent Locations and turn it off.

6. Check for software updates. Software updates will often contain fixes that enhance battery life. You can check for OS updates right from the phone, instead of using a USB cable and syncing with iTunes. 7. The old power-saving standbys still help. You can still do all the basic, old-school things to improve battery life, such as reducing screen brightness, disabling Wi-Fi and Bluetooth, and so on. The one that helps most here, in my experience, is screen brightness, but you still need to crank it up to see the Retina Display in bright sunlight.

8. Consider a battery case or an add-on battery. Battery cases from Kensington, Mophie, and other manufacturers combine a hardware enclosure, which protects your phone, with an extended battery that can double your iPhone's endurance. 70; one favorite is our Editors' Choice, the Unu DX Protective Battery Case for iPhone 5, and we also like the Phonesuit Elite Battery Case and Mophie Juice Pack Plus.
