Recently, a technology website Mydrivers A Chinese company conducted a battery life test on iPhones, comparing different iPhone 13 and iPhone 14 models. The devices used the same Wi-Fi connection, and screen brightness and volume were set to the same level.
iPhone 13 Pro Max is durable.
In the first test, Mydrivers We played videos on Douyin continuously for 30 minutes. The results showed that the iPhone 14 Pro was the fastest battery drainer, dropping to 97%. The remaining devices experienced a drop of about 1-2%.
In the second test, involving 30 minutes of browsing Weibo, watching 1080p videos, and performing various other tasks, the iPhone 13 Pro Max once again proved superior, retaining 90% battery after two hours of continuous use. The iPhone 14 Pro Max came in second with 87% remaining battery.
The next 90 minutes, Mydrivers We used the WeChat app for messaging, listening to music, and reading news. The results showed that the iPhone 14 Pro was the first device to have its battery drop to 60%. The iPhone 13 Pro Max, however, still had 72% battery remaining after 30 minutes of use.
Next, after 90 minutes of 4K video recording and downloading Genshin Impact, the iPhone 13 Pro Max still had 50% battery remaining, followed by the iPhone 14 Pro Max with 45%. Meanwhile, the iPhone 13, iPhone 13 Pro, and iPhone 14 had 35% and 27% battery remaining, respectively.

According to the MydriversThe iPhone 13 Pro and iPhone 14 Pro were the first two devices to shut down after lasting 6 hours and 47 minutes. This shows that the battery capacity on the iPhone 14 Pro hasn't changed much compared to the previous generation.
Meanwhile, the iPhone 14 boasts a battery life of 7 hours and 24 minutes, slightly better than the iPhone 13's 7 hours and 13 minutes. At the point of the iPhone 13 and 14 shutting down, the iPhone 13 Pro Max still had 20% battery remaining, while the iPhone 14 Pro Max only had 15%.
Ultimately, the top-of-the-line iPhone 14 stopped working after 8 hours and 31 minutes. Surprisingly, however, the iPhone 13 Pro Max was the last one standing, lasting 9 hours and 3 minutes, 30 minutes longer than the iPhone 14 Pro Max.
Experiment of Mydrivers Tests have shown that the battery capacity on the iPhone 14 and iPhone 14 Pro models does not differ significantly from their predecessors.
However, despite being the top-of-the-line Pro Max model, the iPhone 14 Pro Max this year falls short of the iPhone 13 Pro Max in terms of battery life. This difference is understandable, though, as the Pro Max's battery is only 4.323 mAh, lower than last year's.
Battery-draining features on the iPhone 14
In addition, the technology page iDB We also conducted a battery life test on the iPhone 14 Pro Max, and the results showed that the device's battery drained significantly faster than its predecessor.
Furthermore, in practical terms, writer Jason Cipriani Cnet He considers battery life a disappointing aspect of the iPhone 14. The device doesn't seem to meet his daily usage needs, unlike the durable iPhone 13 Pro Max he used before.

To explain this difference, iDB There are many reasons why the iPhone 14 Pro Max lags behind its predecessor in terms of battery life.
Among these, Always-On is a new feature introduced by Apple on its latest smartphone line. Although it promises to dim the screen when the phone is locked to save battery, this feature still consumes a certain amount of power to continuously display information such as the time, notifications, etc.
In addition, this year's Pro models have screens with a standard brightness of 1.000 nits and a maximum brightness of up to 2.000 nits in bright sunlight. Meanwhile, the iPhone 13 Pro and Pro Max only reach a maximum brightness of 1.200 nits. This difference will cause the battery on the iPhone 14 Pro to drain faster.
However, the iPhone 13 Pro Max's superiority over the iPhone 14 Pro Max contradicts Apple's previous claims. The tech company stated that the iPhone 14 boasts the most impressive battery life of its smartphone line to date.
Specifically, according to MacRumorsApple claims that all iPhone 14 models have upgraded battery capacity compared to previous iPhones, except for the iPhone 14 Pro Max, which has a smaller battery than last year's generation.
The iPhone 14 has a 3.279 mAh battery, the iPhone 14 Pro has a 3.200 mAh battery, and the iPhone 14 Pro Max has a 4.323 mAh battery. Notably, the iPhone 14 Plus, replacing the mini version, becomes the iPhone with the largest battery, at 4.325 mAh.
Regarding battery life, Apple also stated that all iPhone 14 models have batteries that can last all day. According to the specifications on the company's website, video playback time on all three models—iPhone 14, iPhone 14 Pro, and iPhone 14 Pro Max—is more than 1 hour longer than the previous generation.
