As a result of the iPhone 15 Pro drop test, there is a possibility that ``the back glass is more likely to break than before'', and the iPhone 15 Pro Max's glass can break just by pressing with your finger.
The iPhone 15 Pro and iPhone 15 Pro Max, which were released on September 22, 2023, not only changed the housing from stainless steel to titanium, but also adopted a mechanism that makes it easier to remove the back glass. There are several changes that are difficult to notice visually,

The following is a video of a drop test conducted by YouTube channel AppleTrack in which the iPhone 15 Pro and iPhone 14 Pro are dropped to the ground multiple times. The iPhone 15 Pro's titanium frame is more impact-resistant than the iPhone 14 Pro's stainless steel frame, making it less prone to scratches and dents, but the back glass quickly cracked.

First, hold the iPhone as shown below and drop it so that it falls from the bottom.
You can see that the frame of the iPhone 14 Pro is dented due to the impact when it was dropped.
On the other hand, there are no dents in the frame of the iPhone 15 Pro.
The second fall was from a higher position.
No major changes.
The third drop test is performed from an even higher position.
The iPhone 15 Pro also appeared to have scratches on its frame, but the marks disappeared when I rubbed it with my finger.
The fourth drop test is performed by holding the iPhone so that it falls from the back glass.
Although the display glass and back glass of both the iPhone 14 Pro and iPhone 15 Pro were not broken, there were scratches around the main camera lens of the iPhone 14 Pro.
I changed height and fell for the fifth time.
At this point, the back glass of the iPhone 15 Pro finally cracked.
On the other hand, there are no cracks on the back glass of the iPhone 14 Pro.
Sixth drop test at different heights.
Even with this, no cracks will appear on the iPhone 14 Pro.
7th time
No major changes to iPhone 14 Pro and iPhone 15 Pro.
8th time. From here, drop the iPhone with the display facing down.
There are no cracks in the display glass.
9th time
Finally, the top right corner of the iPhone 15 Pro's display glass cracked. This seems to be due to the curved edges of the display glass in the iPhone 15 series.
Tenth drop test with increased height.
11th time
A crack in the back glass of the iPhone 15 Pro has spread.
12th time
I got a scratch on the edge of my iPhone 15 Pro.
The 13th test of dropping the iPhone from a higher position.
The back glass of the iPhone 15 Pro is cracking.
Additionally, the bottom half of the display no longer displayed accurately and touch operations were no longer possible.
On the other hand, the iPhone 14 Pro still has no cracks on the back glass or display glass.
The 14th drop test was a fall from a height of two stories or higher.
The iPhone 15 Pro was cracked into pieces.
The lens part of the main camera on the back has been separated.
The back glass of the iPhone 14 Pro finally broke.
The display glass also has cracks.
However, touch operations are possible.
I was also able to take a selfie.
Regarding the reason why the iPhone 15 Pro's back glass cracks more easily, Apple-related media 9to5Mac says, ``Titanium is harder than stainless steel and cannot absorb shock, so it is difficult to absorb shock when dropped. 'It may not be able to disperse completely and cause the glass to break.'
However, regarding this type of drop test, 9to5Mac says, ``This type of test is known to be unscientific, and to find out if the iPhone 15 Pro's back glass is really susceptible to breaking, more people need to do the same.'' We need to take into account that we need to carry out testing.'
Another gadget YouTuber, JerryRigEverything, also conducted his own durability test and released a video. We have conducted a heat resistance test using a lighter, a blade resistance test using a cutter, and an abrasion resistance test using sandpaper, all of which we passed without any problems.
However, when I pressed my thumb into the back glass of the iPhone 15 Pro Max, the back glass easily broke. JerryRigEverything said, ``I have been conducting durability tests on smartphones for about 11 years, and most smartphones do not break.In particular, iPhones have not broken at all so far.However, the back glass of iPhone 15 Pro Max It cracked incredibly fast.”
JerryRigEverything explained that the back glass of the iPhone 15 Pro Max broke easily because titanium has five times the tensile strength of aluminum, so the back glass may not be able to withstand pressure and bending. I'm guessing.
Meanwhile, in the video, JerryRigEverything also presses hard on the back glass of the iPhone 15 Pro with his thumb, but the back glass did not break.
Regarding JerryRigEverything's durability test, 9to5Mac's comment section said, ``Although these are interesting results, please remember that a sample size of 1 has no statistical meaning. Similar tests will need to be done on more devices to see if this is reproducible, and JerryRigEverything previously tested the Moto Razr Plus and found that the back glass popped out with just the pressure of your thumb. However, in another video posted a month later, I repeated the same test on multiple Moto Razr Plus and the back glass did not break. In other words, we cannot conclude from this durability test alone whether or not the iPhone 15 Pro Max's back glass has a structural defect that makes it susceptible to breakage.'
In addition, Apple has significantly reduced the cost of repairing the back glass on the iPhone 15 series.
