The autonomy of all versions of the iPhone 15 was compared with the iPhone 14 and 13

YouTuber Mrwhosetheboss decided to check how the autonomy of the new iPhone 15 comparable to previous models. To do this, he took four new smartphones from 2023, as well as the iPhone 14, 14 Pro Max and 13 Pro Max - the latter was still winner of similar tests on the author's channel, so he was included to find out if Apple had released a new king autonomy.

The blogger took new smartphones with a maximum battery capacity of 100%, set the same brightness and volume, and also connected all devices to the same Wi-Fi network.

As often happens in such tests, the blogger simulated the daily activities of an ordinary user. Thus, the test began with an hour of TikTok, after which only the iPhone 15 Pro (89%) dropped below 90% charge; the remaining models had 93-96% charge remaining.

Next, the devices survived an hour of listening to music on Spotify with the screen on (but without clips), an hour of generating ChatGPT 4 (the neural network was asked over and over again to write 100 reasons why cats are better than dogs) and a two-hour call to Zoom. At this stage the results were as follows:

• iPhone 15 Pro Max - 69%;
• iPhone 15 Pro - 52%;
• iPhone 15 Plus - 70%;
• iPhone 15 - 64%;
• iPhone 14 Pro Max - 61%;
• iPhone 14 - 53%;
• iPhone 13 Pro Max - 66%.

Why does the iPhone 15 Pro perform worse than the iPhone 15 and even the iPhone 14? Because of the Pro Motion display. It can change the refresh rate from 120 to 10 Hz, while younger models have the standard 60 Hz available. During the tests, the picture on the screen was constantly changing, which is why the iPhone 15 Pro set a higher refresh rate and consumed more power. But in applications with static images (for example, reading and audiobooks) it would have an advantage.

The next tests are an hour of meditation in Headspace, recording video on the front camera and watching videos on YouTube. 8 hours of load ended with the following results:

• iPhone 15 Pro Max - 37%;
• iPhone 15 Pro - 15%;
• iPhone 15 Plus - 42%;
• iPhone 15 - 24%;
• iPhone 14 Pro Max - 27%;
• iPhone 14 - 13%;
• iPhone 13 Pro Max - 33%.

Then the race to exhaustion began: 2 hours of mobile games and a sleep monitoring application until all smartphones were charged. Here are the final results (anything less than 10 hours did not survive the games stage):

• iPhone 14 - 9 hours 2 minutes;
• iPhone 15 Pro - 9 hours 20 minutes;
• iPhone 15 - 9 hours 57 minutes;
• iPhone 14 Pro Max - 10 hours 54 minutes;
• iPhone 13 Pro Max - 11 hours 19 minutes;
• iPhone 15 Pro Max - 11 hours 41 minutes;
• iPhone 15 Plus - 13 hours 19 minutes.

This isn't the first time the Plus version has outperformed the Pro Max (we had a similar result observed iPhone 14 Plus and 14 Pro Max), but what's striking here is how much longer the Plus lasted. If autonomy is important to you and you don't mind large screens, this model is definitely worth paying attention to.
