I bought an iPhone 14 Pro last year, and this year I saw that the iPhone 15 bought by a colleague was broken. In addition to the industry's first 3nm chip, the iPhone 15 series also debuted a titanium alloy frame. When I watched the press conference, I felt that the titanium alloy frame was just a toothpaste upgrade, and it didn’t have much effect. But after I got the real phone, my mind changed. Today we will compare in detail the differences between titanium alloy and stainless steel frames.

Titanium alloy material effectively reduces weight
First, let’s take a look at the new titanium alloy material. The titanium alloy material used in the iPhone 15 Pro is relatively high-grade and belongs to grade 5 titanium alloy. This material is widely used in aviation and medical fields. Apple officials say that this material is the same as the Mars rover. Titanium metal has the characteristics of high strength, high toughness and corrosion resistance, and it also looks very high-end in visual appearance.
Previous high-end iPhone models basically used stainless steel middle frames. Stainless steel sounds a level lower than titanium alloy, and the disadvantages of stainless steel frames have been obvious over the years. The most criticized one is the weight issue.
After changing to titanium material, the iPhone has successfully lost weight. The iPhone 15 Pro is much lighter in the hand than the previous model. It is no longer a brick machine. The officially announced weight of the iPhone 15 Pro is only 171g, which is a full 35g less than the 206g iPhone 14 Pro. If you are a ProMax user, your perception of lightweight will be even more obvious.
Secondly, the aluminum alloy frame will have serious scratch problems. This is because the hardness of stainless steel is low. Even if you use it very carefully and wear a mobile phone case, you will inevitably have several scratches. Let alone using it bare metal, it will be all spent in two months. The iPhone 15 Pro has just been released, and it will take time to verify its durability. However, I believe that titanium alloy can definitely solve the hardness problem of stainless steel.
Titanium alloy is not perfect
But the iPhone 15 Pro cannot be said to be a complete victory, because the appearance of the new metal brushing process does not satisfy everyone. Many people feel that the design looks like a sink or a steel ball.
Moreover, the titanium frame does not solve the problem of stainless steel frames being easily contaminated by fingerprints. It is reported that after the iPhone 15 Pro is used for a period of time, there will be a color cast problem at the power button and volume button.
It is worth mentioning that the titanium frame is not entirely made of titanium, but the surface is covered with titanium, and the underlying material is 6013-T6 aluminum alloy. Of course, this kind of aluminum alloy material is also very good, and it also has the characteristics of high strength. It is still necessary to understand this clearly before buying.
Not short of money, just close your eyes and change it
So, is it necessary to replace your mobile phone with a new titanium one? It was very exciting at first. But after thinking about it again and again, I have to wear a case to use the iPhone 15 Pro. The texture of the titanium metal is not felt. The only advantage is that it is thin and light. Spending thousands of dollars more for those few dozen grams doesn’t feel very necessary.
Because the other upgrade points of the iPhone 15 Pro do not arouse much interest in me. Although the A17 Pro is made of a 3nm process, the actual performance improvement is just that. It has already had excess performance, and the A16 is enough for me. The upgrade of the imaging system is also painless, and the new sensor will not improve the experience too much. Therefore, most of the friends holding iPhone14Pro should go there for the appearance. My suggestion is for users who want to renew AC+ every year or if they don’t have enough money to replace it. If the budget is not that sufficient, you should consider it.
