iPhone 14 Pro Max and iPhone 14 screen

If you’re planning to upgrade to one of Apple’s newer iPhones, you’ll definitely want to know about the iPhone 14 battery life, and results vary slightly depending on the model. Of course, there are many ways to measure durability, but we evaluate each phone using our own testing to see which phone does well enough to make our list of the best battery life.

The Tom’s Guide battery test includes continuous internet surfing over 5G with the screen set to 150 nits screen brightness. We run this test with every phone we’ve reviewed, including the iPhone 14, iPhone 14 Plus, iPhone 14 Pro, and iPhone 14 Pro Max.

Apple doesn’t list battery sizes for its phones, but new phones have reported breaking down and regulatory filings. That’s why we’ve included the following along with the runtime for each handset. You’ll also find battery test results from comparable smartphones to put iPhone 14 battery life results in context.

iPhone 14 battery life

The regular iPhone 14 lasted a solid but unobtrusive 9 hours and 28 minutes in our battery test. We find anything over 11.5 hours great.

Apple’s 6.1-inch handset has a relatively small 3,279mAh battery, but it actually outlasted the Galaxy S22’s larger 3,700mAh battery, which translates to an 8:02 runtime.

The Google Pixel 7 averaged a poor 7 hours and 14 minutes, and that’s with a sizable 4,355mAh battery. So overall, the iPhone 14 wins among smaller flagship phones in terms of battery life.

iPhone 14 Plus battery life

This is where things get really interesting. Apple released the iPhone mini for the iPhone 14 Plus this year, and it turned out to be a great option for anyone looking for a big screen and long battery life at a low price.

The iPhone 14 Plus and its 4,325 mAh battery surfed the internet over 5G for 11 hours and 57 minutes. That’s good enough for our best phone battery life list, and significantly higher than the 10:26 result of the Galaxy S22 Plus with a 4,500mAh battery. Thus, you get about 1.5 hours more endurance than Samsung’s similarly sized phone.

The Pixel 7 Pro isn’t even close as it averaged 7:54 in the 5 battery tests, and that’s with a 5,000mAh battery.

iPhone 14 Pro battery life

The iPhone 14 Pro’s 3,200mAh battery took 10 hours and 13 minutes to run out, compared to 9:28 for the regular iPhone 14 and its 3,279mAh battery.

Now, you might wonder why the iPhone 14 Pro took longer than the regular iPhone 14 when they have the same size screen and the iPhone 14 Pro has a slightly smaller battery (probably because they have the larger camera system). And I have a few theories.

First, the iPhone 14 Pro has a more efficient 4nm A16 Bionic processor, while the iPhone 14 has an older A15 Bionic chip. And the iPhone 14 Pro can dynamically scale the screen refresh rate from 120 Hz to 1 Hz, while the iPhone 14 stays at 60 Hz. Reducing it to 1 Hz while the screen motion is stable may extend the battery life.

iPhone 14 Pro Max battery life

The iPhone 14 Pro Max is clearly the champion when it comes to battery life. Its 4,323 mAh battery lasted an epic 13 hours and 39 minutes on average. This beats the 10:18 runtime of the Galaxy S22 Ultra’s 5,000mAh battery by over 3 hours.

This 6.7-inch iPhone lets you easily get through more than a day of use without having to charge it. It even lasts about 1.5 hours longer than the similarly sized iPhone 14 Plus.

As a result

If you really care about battery life, there are two new iPhones that should be on your shortlist: the iPhone 14 Plus and the iPhone 14 Pro Max. The 6.1-inch iPhone 14 and iPhone 14 Pro offer decent staying power, especially for their size, but if you want to leave the charger behind, two 6.7-inch iPhones are the way to go.

It’s also worth noting that Samsung and Google are running circles around their closest rivals when it comes to iPhone 14 Pro Max’s battery life.
