iPhone 15 Pro Max back glass cracks within seconds in new durability test

The iPhone 15 Pro and iPhone 15 Pro Max feature an all-new chassis design made out of what Apple says is grade 5 titanium. A drop test video yesterday raised early concerns about the durability of this new design, particularly as related to the new curved edges.

Now, JerryRigEverything has posted his annual durability test with the iPhone 15 Pro and iPhone 15 Pro Max, and he has some concerns…

Throughout the durability test, we can see the new grade 5 titanium put through scratch testing, heating testing, sandpaper, and more. As expected, the titanium does indeed scratch when you take a knife to it. The matte back glass, however, is far more scratch resistant.

The display also fares quite well during the scratch testing as well, as do the three camera covers on the back of the iPhone 15 Pro. But things get more interesting pretty quickly.

“It’s time to see if the new blended aluminum titanium grafted hybrid structure compromises the structural integrity of the iPhone 15 Pro Max,” JerryRigEverything says as he starts to put pressure on the device. Within just a few seconds, you hear a snap and the back glass has completely shattered.

“I did not see that one coming,” he says. “You’ve been watching me durability test smartphones for about 11 years now, and most phones do not break. iPhones especially do not break, like ever. And [the iPhone 15 Pro Max’s] snap was abnormally quick.”

Internally, the iPhone 15 Pro Max survives the test. The screen and frame of the device are also both unscathed. It’s just the back glass that succumbs to the pressure.

JerryRigEverything speculates that this could be due to the titanium having five times the amount of tensile strength as aluminum, leading to the glass back not being able to withstand even small amounts pressure and flex. On the bright side, Apple has made it far cheaper to replace the iPhone 15 Pro’s back glass this year.

You can check out the video below for the full details. It’s a fascinating look at the iPhone 15 Pro’s new design, but also with some interesting tidbits about titanium itself.

In David Guetta’s hit song “Titanium” from 2011, Sia sang: “You shoot me down, but I won’t fall. I am titanium.” It looks like the same can’t be said for Apple’s version of titanium in the iPhone 15 Pro.

iPhone 15 Plus takes the crown in battery life test, beating all previous iPhone models

Following the iPhone 15 release on Friday, the first battery test results are coming in. Apple touted the efficiency of the 3nm A17 Pro chip, so anticipation was high for the iPhone 15 Pro and Pro Max to take the top spot.

Indeed, the Pro Max outlasted all previous iPhones in Mrwhosetheboss’s test. But it was actually bested by the 15 Plus, which racked up more than 13 hours screen on time, and now holds the title of longest iPhone battery life on record.

Apple’s own tech specs page reports battery life in terms of longevity for continuous audio playback and video playback sessions. According to Apple’s numbers, the iPhone 15 Pro Max lasts the longest on streaming video playback with 25 hours compared to 20 hours for iPhone 15 Pro and iPhone 15 Plus.

However, on audio playback, the Max is rated for 95 hours while the Plus hits triple digits at 100 hours. Apple’s numbers give a decent benchmark to compare across models, but it’s hard to deduce real-world battery life times from them, as day-to-day phone usage is usually more taxing than just watching video or playing music.

Mrwhosetheboss attempts to simulate a more realistic daily usage pattern, cycling through power draining activities like watching TikTok videos, Zoom video chat, recording video in the camera, and playing games. The phone screen stays on the entire time until the battery is depleted and it turns off.

The previous title holder was the iPhone 13 Pro Max, as battery life dipped a little with the 14 series. As seen in the video, all iPhone 15 models beat out their previous-generation counterpart.

Of the newest generation phones, the iPhone 15 Pro died first, followed by the iPhone 15. The 15 Pro lasted for 9 hours and 20 minutes. The base iPhone 15 endured another half an hour, clocking in at just under 10 hours of runtime.

The 15 Pro Max easily lapped the field, staying alive for another hour and a half of battery life, hitting 11 hours and 41 minutes. The 15 Plus almost beat the Max by the same margin though, achieving a staggering 13 hours and 19 minutes in the test.

The previous best performer, the 13 Pro Max, managed 11 hours and 19 minutes in contrast.
