Samsung S22, Pixel 6, & iPhone 13: Which one has the Best Battery Life

December 12, 2021

Battery life is one of the parameters by which smartphones are chosen. Some people choose their new phone based on a fact that it will last a long time on a single charge. With big screens and powerful chipsets, it is becoming harder and harder to find a phone that will last longer than a day on a single charge.

So, if youā€™re one of the people who are looking to treat themselves with one of the newest flagship releases, here is what you need to know before buying either Pixel 6, S22, or iPhone 13.


Apple iPhone 13

iPhone 13, 13 Pro, and 13 Pro Max were compared in terms of autonomy with Android smartphones of different years of release and they showed excellent results compared to competitors.

First, the author outlined several new parameters that have been improved or added to the iPhone 13. These are 120 Hz refresh rate, VRR technology, and an advanced OLED display. After comparing the power consumption of the iPhone 11 Pro, 12, 12 Pro, 13, 13 Pro, it turned out that the Pro series (except for the iPhone 11) has higher power consumption. The reason for this is unclear.

The iPhone 13 series also features an increase in battery capacity. Compared to the 12th version, it has increased, depending on the model, by 8 (the regular model), 14.6, 9.9, or 18 percent.

Then the expert moved on to testing the actual battery life of the iPhone 13 and other devices. The tests were carried out in two modes: at a screen refresh rate of 60 Hz and at the maximum possible refresh rate (in the case of the 13th, this is 120 Hz).

According to the results of testing the autonomy of the iPhone 13 Pro (16.62 hours), iPhone 13 (16.82 hours), and 13 Pro Max (21.68 hours) were in the top three at a frequency of 60 Hz. In addition, the author adds that the battery life of the iPhone 13 increased by 34 percent compared to the iPhone 12.

But in the test with a frequency of 120 Hz, the first and third lines were taken only by the iPhone 13 Pro Max and 13 Pro, respectively. In second place is the ASUS ROG Phone 5 with a score of 14.93 hours. Apple products lose 13.5% and 14.5% autonomy compared to the previous test.

But how does this compare to the other two phones?

Google Pixel 6

Finally a decent autonomy in a Pixel!

I have had several Google Pixels and I always suffered a run-in with autonomy. In general, Google contains energy expenditure very well, it is one of the characteristics that enrich these phones. And in the Pixel 6, there is great battery management and a fairly large capacity of the same with 4,600 mAh. Baggy for a Pixel, of course.

On average, a day and a half with intensive use and a 90 Hz refresh rate for the screen are more than usual, even with games and high multimedia consumption. Saving on such use it is easy to stretch the battery over two days!

The Pixel 6 supports 30 W fast charging (Power Delivery 3.0) via cable and 21 W wireless charging. Of course, it does not include either of the two chargers: the content of the package is limited to a USB C cable at both ends and an adapter to USB A. During my experience charging the phone, I managed to do it from zero to 100% in about an hour and a quarter using the fast charger of the iPad Pro (25 W) and somewhat less using the charger of the Samsung Galaxy Note 20 Ultra (25 W, Power Delivery 3.0). During the process, the temperature was raised without causing any danger in use.

Then I leave the charging times using the fast charger of the iPad Pro. The values are similar to those given by Google itself, they should not be far from the maximum charge capacity allowed by the Pixel 6. It must be taken into account that the " Smart Charge" was on, hence the extended time during the latter part of the cycle.

  • 5-minute charge: 8% battery.

  • 10-minute charge: 16% battery.

  • 20-minute charge: 32% battery.

  • 30-minute charge: 48% battery.

  • 50-minute charge: 74% battery life.

  • Total: 1 hour and 45 minutes.

One last detail is the reverse wireless charging - the Google Pixel 6 can charge other devices with Qi, such as mobile phones or headphones.

Samsung S22

As a rule, the successor is slightly superior in autonomy to its predecessor, but this rule may not work in the case of the Galaxy S22. In terms of autonomy, the Samsung Galaxy S22 can be a disappointment as battery capacity can be reduced and all for the sake of compactness.

Sammobile managed to find a photo with an EB-BS901ABY battery in one of the certification authorities in South Korea. There is speculation that the battery is for the Galaxy S22, which received model number SM-S901B. According to the battery picture, its nominal capacity is 3590mAh and typical is 3700mAh.

If all assumptions are correct, then it turns out that the battery capacity of the Galaxy S22 will be 300 mAh less than what the Galaxy S21 has. The battery could have been put under the knife because, according to rumors, the basic flagship of the series will be compact. So, the diagonal of the screen should be 6.02 inches versus 6.2 inches from its predecessor.

If you have seen, renders of the Galaxy S22 were leaked to the network which confirm that in terms of appearance the new product will not differ much from its predecessor. But it should get quite a power boost with a 120Hz LTPO display, 45W fast charging, and an Exynos 2200 chipset with AMD graphics.

How well will Samsung combine the smaller battery with more powerful specs remains to be seen but Iā€™m not confident that this new idea from Samsung will beat the likes of Pixel 6 and iPhone 13. Luckily, there are numerous ways to boost the battery life, such as power banks, battery cases, and high-end smartcases.
