How the iPhone 13 breaks the laws of physics

iPhone 13

Displays with outstanding performance are used in all iPhone models in 2021, but in Phone 13 Pro and iPhone 13 Pro Max they are the best and most advanced. These are LTPO OLED displays from Samsung. Samsung used similar displays in the Note 20 Ultra in 2020 and the Galaxy S21 Ultra in 2021. These screens are more expensive, but they also have unique features. In addition to technical advantages, they have one more thing – they consume less energy than conventional displays. On the iPhone 13 Pro and iPhone 13 Pro Max LTPO, the display saves approximately 100 milliwatts. For smartphones, this is a lot. The energy costs of adaptively changing the refresh rate of screens are offset by this savings almost completely. But beauty and quality require sacrifice, the best displays in the world consume more energy, there is no escape from this. The screens on the iPhone 13 and iPhone 13 mini aren’t as advanced as the high-end models.

They do not know how to change the refresh rate of the screen – but otherwise they are not inferior to the screens of the Pro models. They consume energy with no less greed. The battery capacity is smaller than the competition, the screens need the same amount of power as the competition, but the iPhone 13 holds a charge longer. Without magic, this is impossible – without it, it could not have done. Every iPhone 13 has a magic crystal. This is the Apple A15 Bionic. Apple spends a lot of time and money solving problems that other companies do not pay attention to. There is nothing supernatural in this magic. Except for the results. In public testing, iPhone 13 batteries performed well. They have first place. Even the iPhone 13 mini scores well, never making it into the top three – but its tiny battery can handle everything a typical user might need in real life.

iPhone 13 battery capacity

The battery capacity of the iPhone has not grown very significantly, but the autonomy is still like

Apple is known to spend a lot of time and money to make the iPhone as thin and light as possible. The company is criticized and ridiculed for this, but weight and thickness play a significant role in the popularity of the iPhone. This year, this important aspect for the company was sacrificed. The new iPhones are a quarter of a millimeter thicker and heavier. Grams or tens of grams. To increase battery capacity. A sacrifice would not be enough, so the placement of the elements in the iPhone case was redesigned from scratch to free up as much space as possible for the batteries. Eliminating, at the same time, the compromises accumulated over several generations of iPhone. Battery capacity in all iPhone 13 models has increased compared to the previous generation.

In the iPhone 13 Pro Max – by 18%. Up to 4352 mAh. In iPhone 13 by 14.6% – up to 3227 mAh. In the iPhone 13 Pro, it grew by only 9.9%, as a result, it is less than the “non-Pro” iPhone 13 – 3095 mAh. From the iPhone 13 mini, they did not make a prize horse, the capacity of its battery increased by only 8%, to 2406 mAh. The iPhone 13 Pro Max seems like a monster compared to other iPhone models of 2021, but compared to the batteries of elite Android smartphones, its 4352 mAh is almost a shame to mention. On Android, 5000 mAh batteries are no longer uncommon, there are even 6000 mAh batteries. In terms of common sense, the iPhone 13 has no chance of winning in the competition for the title of smartphone with the longest battery life. They are in different weight classes. But nevertheless, iPhone 13 participate in these competitions, and as a rule, win them.

How long does an iPhone hold a charge

iPhone 13 holds a charge better than many Android flagships

This time, the iPhone 13 was tested in tests in which, in addition to battery capacity, screen power consumption plays an important role. On fully charged smartphones, continuously, until the battery charge drops to zero, browse the web. They say that it is when browsing the web that screens show their strengths and weaknesses best. We will omit the theoretical justifications, I suggest simply believing that everything is so.

These tests have been running since 2016, experts are interested in their results, and the iPhone 13 has results in these tests that I really like. The iPhone 13 was tested in two tests – in the first of them, the refresh rate of the screens of the tested smartphones should be 60 Hz. On smartphones with a fixed refresh rate, this is the standard. Smartphones in which the screen refresh rate is variable can be tightly set to a refresh rate of 60 Hz.

Below are the results of the five smartphones that performed best on this test:

  • iPhone 13 Pro Max – 21.68 hours;
  • iPhone 13 – 16.82 hours;
  • iPhone 13 Pro – 16.62 hours;
  • ASUS ROG Phone 5 – 16.60 hours;
  • ASUS ROG Phone III – 16.51 hours.

The Samsung Galaxy S21 Ultra (with S888), the main competitor of the iPhone 13, ranked seventh, it managed to last 15.91 hours. In 13th place is the iPhone 11 at 14.03 hours. iPhone 13 mini in 32nd place, it lasted 10.70 hours. The result of mini is considered quite good.

In the second test, smartphones compete at the highest possible screen refresh rate for them. Otherwise, this test is similar to the first. All devices in the top five have a maximum screen refresh rate of 120 Hz. Smartphones with a fixed screen refresh rate do not participate in this test. Here are the top five so far:

  • iPhone 13 Pro Max – 18.77 hours;
  • ASUS ROG Phone 5 – 14.93 hours;
  • iPhone 13 Pro – 14.20 hours;
  • Samsung Galaxy S21 Ultra – 13.98 hours;
  • Xiaomi 11T – 13.18 hours.

For obvious reasons, only two iPhone models participated in this test. In second place is the ASUS ROG Phone 5 smartphone, with the total power of two batteries of which is almost twice the battery capacity of the iPhone 13 Pro. 6000 mAh vs 3095 mAh.
