The DXOMARK company tests smartphones with very scientific protocols. According to them, the Samsung Galaxy S23 Ultra is the best smartphone in the premium segment when it comes to battery life. It is far ahead of the iPhone 13 Pro Max and iPhone 14 Pro Max, often cited as champions in this area.
If there is one point where the Samsung Galaxy S23 Ultra impressed us, it is on its autonomy. On light use, the phone lasted 48 hours straight without any problem, a real improvement compared to phones from years past, and more broadly compared to Samsung smartphones before.
DXOMARK, a company specializing in scientific testing of phones, placed it very high in its ranking devoted to autonomy. With 142 points, it is 6th of all the smartphones tested, which is already a good performance. In front of it, we essentially find smartphones under 600 euros, which could be described as entry to mid-range and which therefore offer a slightly lower level of service on many other points (photos, screen, quality of manufacturing, etc.)
Once faced with premium smartphones (above 800 euros), the Galaxy S23 Ultra imposes itself and obtains a first place. With 142, it is 2 points ahead of the Asus Rog Phone 6, but also 6 points ahead of the iPhone 13 Pro Max and 9 points ahead of the iPhone 14 Pro Max or the Vivo X80 Pro. The iPhones are often cited as champions of autonomy, ahead of them by a good margin, so we can say that this first place is obtained in a relatively comfortable way.
Why such a good score?
Interestingly, the Galaxy S23 Ultra gets this spot without landing any top score in any of DXOMARK’s sub-scores. Above all, this demonstrates a good general balance and an ability to stand above the fray in terms of autonomy in the premium segment. “Flagships frequently face battery performance issues due to their new power-hungry features. This is where careful hardware and software integration plays an important role in battery performance”reads the company’s report.
The Galaxy S23 Ultra displays, according to their tests, a very good autonomy in moderate use, an excellent autonomy for watching videos, a low discharge in general. On the side of the points that remain to be improved, DXOMARK underlines a collapse once past the 5% battery and a worse autonomy when using the camera or listening to music.
