Scoring
Sub-scores and attributes included in the calculations of the global score.

Key performances
These key points are derived from the lab measurements during testing and do not figure into the overall score. The lab measurements, however, are used for the overall score.
90th
18th
Pros
- Low residual consumption whether the device is plugged in or not to the wired charger
- Low discharge currents overall
Cons
- Weak autonomy when listening to music and when idle with screen off
- Poor autonomy when calling and using the camera on the go
- Inaccurate battery gauge: 15.6% actual measured capacity shows as 20% on the display
The Samsung Galaxy S23’s global battery score was below the average of our entire database, but the device outperformed its predecessor the Samsung Galaxy S22, particularly in autonomy and efficiency.
With a charge that lasted slightly more than 2 days when used moderately, the Galaxy S23’s autonomy was below average. When testing specific usages, the results varied. Battery performance was decent when watching videos and was good when the device was idle with the screen on. Listening to music or using the camera outdoors, however, showed poor results. Moreover, the battery gauge was inaccurate, showing only 15.6% real capacity remaining when the device’s screen displayed 20.0%
The charging experience was also below average. Wired charging took longer than the mean, but wireless charging was average. The autonomy recovered after a quick 5-minute boost was low at only about 3 hours, which was a contributing factor to its below-average score.
The wireless charger’s efficiency was poor due to high consumption. Despite a small battery, the Samsung Galaxy S23’s autonomy was only slightly below average thanks to low discharge currents overall, meaning that the device is well optimized.
For a device in the Premium price range ($600€ – $799), the Samsung Galaxy S23 ranked just above average in our database, held back by its poor charging experience, despite its excellent efficiency and average autonomy.

Autonomy

Autonomy score is composed of three performance sub-scores: Home / Office, On the go, and Calibrated use cases. Each sub-score comprises the results of a comprehensive range of tests for measuring autonomy in all kinds of real-life scenarios.

Home/Office

A robot housed in a Faraday cage performs a set of touch-based user actions during what we call our “typical usage scenario” (TUS) — making calls, video streaming, etc. — 4 hours of active use over the course of a 16-hour period, plus 8 hours of “sleep.” The robot repeats this set of actions every day until the device runs out of power.
On the go

195
Using a smartphone on the go takes a toll on autonomy because of extra “hidden” demands, such as the continuous signaling associated with cellphone network selection, for example. DXOMARK Battery experts take the phone outdoors and perform a precisely defined set of activities while following the same three-hour travel itinerary (walking, taking the bus, the subway…) for each device
Calibrated

For this series of tests, the smartphone returns to the Faraday cage and our robots repeatedly perform actions linked to one specific use case (such as gaming, video streaming, etc.) at a time. Starting from an 80% charge, all devices are tested until they have expended at least 5% of their battery power.
Charging

Charging is fully part of the overall battery experience. In some situations where autonomy is at a minimum, knowing how fast you can charge becomes a concern. The DXOMARK Battery charging score is composed of two sub-scores, (1) Full charge and (2) Quick boost.
Full charge

184
Full charge tests assess the reliability of the battery power gauge; measure how long and how much power the battery takes to charge from zero to 80% capacity, from 80 to 100% as shown by the UI, and until an actual full charge.

Quick boost

With the phone at different charge levels (20%, 40%, 60%, 80%), Quick boost tests measure the amount of charge the battery receives after being plugged in for 5 minutes. The chart here compares the average autonomy gain from a quick 5-minute charge.
Efficiency

154
The DXOMARK power efficiency score consists of two sub-scores, Charge up and Discharge rate, both of which combine data obtained during robot-based typical usage scenario, calibrated tests and charging evaluation, taking into consideration the device’s battery capacity. DXOMARK calculate the annual power consumption of the product, shown on below graph, which is representative of the overall efficiency during a charge and when in use.
Charge up
Samsung Galaxy S23 (Snapdragon)
205
The charge up sub-score is a combination of four factors: the overall efficiency of a full charge, related to how much energy you need to fill up the battery compared to the energy that the battery can provide; the efficiency of the travel adapter when it comes to transferring power from an outlet to your phone; the residual consumption when your phone is fully charged and still plugged into the charger; and the residual consumption of the charger itself, when the smartphone is disconnected from it. The chart here below shows the overall efficiency of a full charge in %.
Discharge

194
The discharge subscore rates the speed of a battery’s discharge during a test, which is independent of the battery’s capacity. It is the ratio of a battery’s capacity divided by its autonomy. A small-capacity battery could have the same autonomy as a large-capacity battery, indicating that the device is well-optimized, with a low discharge rate.
