The iPhone 15 Pro is Apple’s latest flagship smartphone, and it comes with a number of new features and improvements, including a more powerful processor, a better camera system, and a new design. However, one of the most important questions on many people’s minds is how good the battery life is.
In this article, we’ll take a closer look at the iPhone 15 Pro’s battery life, including how it compares to previous models and other flagship smartphones. We’ll also provide some tips on how to get the most out of your iPhone 15 Pro’s battery.
Overview
According to Apple, the iPhone 15 lineup has the same battery life as last year’s models. The iPhone 15 Pro Max, according to the company, has up to 29 hours of video playback and up to 95 hours of audio playback, while the 15 Pro has 23 hours of video and 75 hours of audio.
Meanwhile, the iPhone 15 Plus is rated for 26 hours of video playback and 100 hours of audio, while the iPhone 15 is rated for 20 hours of video playback and 80 hours of audio.
According to the regulatory filing, the battery capacities are as follows:
- The iPhone 15 Pro Max has a 4,422mAh / 17.109Wh battery, while the iPhone 14 Pro Max has a 4,323mAh battery.
- The iPhone 15 Pro has a 3,274mAh / 12.70Wh battery, while the iPhone 14 Pro has a 3,200mAh battery.
- The iPhone 15 Plus has a 4,383mAh / 16.950Wh battery, while the iPhone 14 Plus has a 4,325mAh battery.
- The iPhone 15 has a 3,349mAh / 12.981Wh battery, while the iPhone 14 has a 3,279mAh battery.
The iPhone 15 Pro and 15 Pro Max Have the Largest Capacity Increases
The biggest battery increases go to the Pro models, which are still a relatively minor increase of just over 2%. iPhone 14 Pro owners, in particular, appear to have experienced more battery capacity loss and overall frustratingly low battery life than owners of previous model years. The iPhone 15 Pro models are equipped with the new 3nm process A17 Pro Apple Silicon, the most power-efficient chip in the lineup. However, it is more powerful, resulting in the same stamina, according to Apple’s figures.
The battery health capacity of the iPhone 14 device lineup is declining faster than previous models, with many customers reporting that their iPhones have lost around 80 percent of their original capacity in less than a year. It will take some time to see if the iPhone 15 series suffers from the same kind of degradation.
Battery Life on the iPhone 15: The Four Models Were All Compared
iPhone 15 Battery Life
According to regulatory filings, the 6.1-inch iPhone 15 has a 3,349 mAh battery. (Apple does not specify battery size.) As earlier mentioned, that is slightly more than the 3,279 mAh battery in the iPhone 14. Despite this, there is a significant increase in runtime.
We ran a test on the most recent iPhone lineups compared to other Android flagships, and the Phone 15 lasted 11 hours and 5 minutes, about an hour and a half longer than the iPhone 14. This time also beats the regular Samsung Galaxy S23 with its adaptive mode screen, but the S23 lasted 11:20 with its screen in 60Hz mode. The iPhone 15 also has a refresh rate of 60Hz.
The Google Pixel 7 only lasted 7 hours and 14 minutes, so it’s not even in the same league.
iPhone 15 Plus Battery Life
The iPhone 15 Plus lasts 14 hours and 14 minutes compared to just under 12 hours for the iPhone 14 Plus. So we’re talking about an extra two hours.
The Galaxy S23 Plus lasts 11 hours 24 minutes in adaptive mode and 12 hours 8 minutes in 60Hz mode, trailing the iPhone 15 Plus by about 2 hours. The OnePlus 11 lasts a maximum of 13:10 minutes, an hour less than Apple’s device.
iPhone 15 Pro Battery Life
According to research, the iPhone 15 Pro has the shortest battery life. The device’s battery life was 10 hours and 53 minutes, 40 minutes longer than the iPhone 14 Pro.
That’s totally okay, considering it’s about an hour ahead of the average smartphone on our test.
However, excellent battery life is mostly defined as 11.5 hours or more. Nonetheless, the iPhone 15 Pro outlasts the Google Pixel 7 Pro by about 3 hours.
iPhone 15 Pro Max Battery Life
If you want serious battery life, the iPhone 15 Pro Max is the best model from Apple. iPhone 15 Pro Max has 14 hours and 2 minutes of battery life, slightly less than the iPhone 15 Plus but more than 20 minutes longer than the iPhone 14 Pro Max.
This easily places the new Pro Max on our list of the best phone batteries. No other major flagship phone tested has provided this endurance level.
Apple Still Has One Major Flaw
While the iPhone may have the best overall battery life, Apple overlooked one feature: charging. The iPhone 15 Pro Max maxes out at the same 27W that Apple claims should yield 50% in 30 minutes but only got to 41% in Tom’s Guide’s tests.
That doesn’t compare to the best Android phones, with the Samsung Galaxy S23 Ultra reaching 57% in 30 minutes and the OnePlus 11 beating them both with a full charge in around 27 minutes.
Even if the next-generation Android flagships gain only a small advantage in terms of battery life, the charging advantage is significant enough to make the difference irrelevant for anyone who can quickly charge for even 10-15 minutes per day.
While we’re glad to see the iPhone finally adopt USB-C, we’re hoping for a charging speed upgrade on the iPhone 16 next year to bring it more in line with the best Android offers.
Conclusion
If battery life is important, I recommend the iPhone 15 Plus or iPhone 15 Pro Max. These phones are more expensive than the smaller models, but you won’t be reaching for the outlet as frequently during the day. And that means a lot to a lot of people.
