Pros
- Low discharging currents in most test cases
- Great autonomy in individual test cases
- Excellent wired charger efficiency
Cons
- Poor autonomy while using social apps outdoors
- Relatively less autonomy regained from 5-minutes quick charging
The Samsung Galaxy S24 Ultra offered a satisfying battery experience during our tests, ranking in the top half of our database. However, compared to its predecessor, the Samsung Galaxy S24 Ultra lost 12 points due to the weaker showing in autonomy and charging.
The Samsung Galaxy S24 Ultra has a 5000 mAh battery, offering 56 hours of autonomy under moderate usage. The device performed impressively in individual test cases, especially when streaming videos, gaming, and idling with the screen on. However, the autonomy declined during our typical usage scenario and on-the-go tests, indicating that the device was not very well optimized.
The charging experience of Samsung Galaxy S24 Ultra ranked slightly over the average among all our tested devices but still came behind the S23 Ultra (Snapdragon). The recommended 45W charger needed 1 hour and 27 minutes to fully charge the battery. The wireless charging duration of 2 hours and 9 minutes was also around the average. On the other hand, the device struggled in the five-minute quick charge test, which yielded only 4 hours and 22 minutes of additional autonomy.
The Samsung Galaxy S24 Ultra’s charge-up efficiency was 75.7%, which is relatively less efficient when compared with other devices. However, the residual power drain was lower than average, regardless of whether the device was plugged in or not. The Samsung Galaxy S24 Ultra’s discharging currents were also generally very low in our individual test cases.
Compared to other devices in the Ultra-Premium segment, the Samsung Galaxy S24 Ultra still had a good showing thanks to its autonomy and efficiency performance.

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.

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

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.

How Charging score is composed
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.

Realme GT Neo 5 (240W)
Realme GT Neo 5 (240W)
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.

How Efficiency score is composed
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.

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 %.

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.
