Preface

In September 2022, Apple’s official website released the iPhone 14 series super-cup flagship iPhone 14 Pro Max, which has more improvements compared to the previous generation 13 series, but whether it is ultimately suitable for users also needs to be considered based on their own circumstances.

This time, the charging head network conducted a simple comparison between the two generations and two super-large cup models. It is believed that the vast majority of users also have purchasing needs for the first two generations of models. This time, actual charging tests were also added, so that users can have a clear understanding of the battery life of their mobile phones when they are out.

product description

Without further ado, let’s take a look at the product.

Both phones do not come with a charger, so the packaging is thinner and lighter, and the sense of damping when unboxing is reduced. You can open it by simply lifting the lid; the same USB-C to Lightning fast charging cable, card pin, and "waste paper" are also included.

Both flagship phones use a 6.7-inch Super Retina XDR display and have a ProMotion adaptive refresh rate, saying goodbye to the long-standing 60Hz refresh rate; the biggest difference is that the 14Pro series no longer has a bangs, but a Smart Island "pill" design.

The position of the side buttons is slightly different from that of the previous generations of iPhone 13 Pro Max and iPhone 12 Pro Max, so personalized phone cases cannot be used universally.

The above picture is a bar chart of the battery capacity of the entire series from iPhone 3G to iPhone 14. It can be seen that the battery capacity of these two mobile phones differs by about 29mAh.

The above icons show the full range of iPhone models that support fast charging. The following article will compare the charging time of these two phones, although they have different capacities.

Maximum charging power comparison

Although the fast charging of iPhone has been surpassed by many domestic manufacturers, it has attracted much attention due to the influence of the product itself. The upgrade of iPhone's fast charging has made us realize that mobile phone charging can also be squeezed. The power is increased by several watts every year, but it can still maintain a 50%-60% charging performance in half an hour.

As this year's super cup, the iPhone 14 Pro Max no longer comes with a standard charger. Instead, it comes with a new original 35W charger. It is tested that the iPhone 14 Pro Max supports a maximum fast charging power of about 27W. Looking at last year's super cup, the iPhone 13 Pro Max seems to have no difference in fast charging, and also supports a maximum charging power of about 27W, both of which have the highest charging power in the entire iPhone series of mobile phones.

Charging comparison

Today we are talking about the fast charging performance of two super-large iPhones. Often, the fast charging power actually tested when getting a new phone is higher than the official nominal power of Apple. Should we choose the 20W fast charging officially recommended by Apple or the higher power PD fast charging?

Let’s first look at the iPhone 14 Pro Max. Here we directly summarize the charging curves of Apple’s 5W, 18W, 20W, 35W, and 140W chargers for the iPhone 14 Pro Max.

The full process diagram of each original charger is drawn as above. The measured maximum charging power of iPhone 14 Pro Max is 27W. After turning off the battery optimization mode, the 5W charger still maintains the original record. For chargers with 18W and above power, the fastest charging rate is the 35W charger one hour ago, or the original charger that supports 9V3A gear can achieve a faster charging rate; but the subsequent power has shown a steady decline, and the charging time is comparable to that of the 20W charger.

Let's take a look at last year's biggest iPhone, the iPhone 13 Pro Max. This time, let's look directly at the PD fast charging stage. At the half-hour point, 30W was slightly faster, charging 49%; at the one-hour point, 96W was faster, charging 84%; to fully charge, 30W and 96W took the shortest time, about 1 hour and 47 minutes.

Summary of charging head network

This time, we briefly talked about the difference between the two super-large iPhones in fast charging. Overall, the iPhone 14 Pro Max has been upgraded in fast charging compared to the iPhone 13 Pro Max. Although the battery capacity of the iPhone 13 Pro Max is 4352mAh, which is 29mAh higher than the 4323mAh of the iPhone 14 Pro Max; but in terms of fast charging power, both the iPhone 14 Pro Max and the iPhone 13 Pro Max support about 27W fast charging.

Let's look at the most concerned charging time. Here we focus on the charger. Let's not talk about non-PD fast charging for now, PD fast charging is here. A 20W charger can charge an iPhone 14 Pro Max by 46% in half an hour, and an iPhone 13 Pro Max by 43% in half an hour. 20W is really not enough for the iPhone Pro Max. For higher-power chargers, chargers that can charge an iPhone 14 Pro Max to 50% in half an hour are 30W and above; chargers that can charge an iPhone 13 Pro Max to 50% in half an hour are also 30W and above.

Now the charging comparison results of the two super-cup iPhones are already very obvious. For the two super-cup iPhone Pro Max, PD fast charging heads below 30W are indeed not enough; if you want a better charging experience, a 30W~35W charger is an extremely cost-effective choice.
