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.
133rd
26th
Pros
- Good wireless charging time
- Good wired charge efficiency
- Low residual power drained by the wired charger
Cons
- Poor autonomy overall
- Low autonomy recovered after a 5-minute charge
- High residual consumption of the wireless stand
- Inaccurate battery gauge: 16% actual measured capacity shows as 20% on the display
The Samsung Galaxy S23 FE, the special Fan Edition from the S23 series, struggled in most of our battery tests, particularly in autonomy.
When used moderately, the Samsung Galaxy S23 FE provided a bit less than two days of autonomy, which is below average in our database. When testing under individual test cases, the performances were also poor. However, when gaming, the device showed relatively decent autonomy compared with other devices we tested.
The S23 FE’s battery gauge was inaccurate, displaying 20% when the actual measured capacity was 16%, which could impact the user experience. Moreover, the last five percent of power left in the battery drained very quickly.
With a 25W wired charger, the battery’s charging time was average, taking 1 hour and 34 minutes to fully replenish the battery. Wireless charging was quite good, taking around 2 hours to charge the battery fully. A quick 5-minute charge provided an additional 3 hours and 16 minutes of autonomy, which is a bit low compared with other devices.
The S23 FE’s charge efficiency was a bit balanced with a decent wired one but a poor wireless one. Residual consumption of the wired charger itself, whether the fully charged device was still plugged in or not was very low. But the wireless consumption of the stand was among the weakest we have ever tested. Finally, discharge currents were higher than average for most activities, except for gaming, which was average, indicating that the device is not well optimized.
When compared with other devices in the High-end segment ($400 – $599), the Samsung Galaxy S23 FE’s performance in autonomy, efficiency, and charging experience remained poor and below average.

Autonomy
Samsung Galaxy S23 FE
195
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
Samsung Galaxy S23 FE
221
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
Samsung Galaxy S23 FE
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

198
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

218
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

224
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

212
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
Samsung Galaxy S23 FE
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 FE
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
Samsung Galaxy S23 FE
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.
