We subjected the Samsung Galaxy S24 Ultra to our rigorous SBMARK Battery test suite to measure its performance in terms of battery life, charging and efficiency. In the results of these tests, we will analyze how it performed in a series of tests and in several common use cases.

Overview

Key Specifications:

  • Battery capacity: 5000mAh
  • 45W charger (not included)
  • 6.8-inch OLED display, 1440 x 3120, 120 Hz
  • Qualcomm Snapdragon 8 Gen 3 (4nm)
  • Tested ROM/RAM combination: 256GB + 12GB

Pros

  • Low discharge currents in most test cases
  • Great autonomy in individual test cases
  • Excellent wired charger efficiency

Against

  • Poor autonomy when using social apps outdoors
  • Relatively less battery life recovered from the 5 minute quick charge

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 inferior results in terms of autonomy and charging.

The Samsung Galaxy S24 Ultra has a 5000 mAh battery, which offers 56 hours of battery life with moderate use. The device performed impressively in individual test cases, especially when streaming videos, playing games and in idle mode with the screen on. However, battery life decreased during our typical usage scenario and in on-the-go tests, indicating that the device was not very well optimized.

The Samsung Galaxy S24 Ultra’s charging experience ranked slightly above average among all our tested devices, but still fell behind the S23 Ultra (Snapdragon). The recommended 45W charger took 1 hour and 27 minutes to fully charge the battery. The wireless charging time of 2 hours and 9 minutes was also 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 battery life.

The charging efficiency of the Samsung Galaxy S24 Ultra was 75.7%, which is relatively less efficient than other devices. However, residual power consumption was lower than average regardless of whether the device was plugged in or not. The discharge currents of the Samsung Galaxy S24 Ultra 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 performed well thanks to its battery life and efficiency performance.

Test summary

Information on SBMARK battery tests: For scoring and analysis in our smartphone battery reviews, SBMARK engineers perform a series of objective tests over a period of one week both indoors and outdoors. (See our introduction and how we test articles for more details on our smartphone battery protocol.)

How the autonomy score is composed

The battery life score is made up of three performance subscores: Home/Office, On the Go, and Calibrated Use Cases. Each subscore includes the results of a full range of tests to measure battery life in all types of real-life scenarios.

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

Using a smartphone on the move puts a strain on battery life due to additional “hidden” needs, such as the continuous signaling associated with cellular network selection. SBMARK Battery experts take the phone outdoors and perform a series of well-defined activities following the same three-hour travel itinerary (walking, taking the bus, subway…) for each device

Calibrated

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

How the charging score is made up

Charging is a full part of the overall battery experience. In some situations where battery life is at its lowest, knowing how fast you can charge becomes a concern. The SBMARK Battery Charging Score is made up of two sub-scores, (1) Full Charge and (2) Quick Boost.

Full charge

Full charge tests evaluate the reliability of the battery charge indicator; measure how long and how much energy the battery takes to charge from zero to 80% capacity, from 80 to 100% as shown by the user interface, and until actually fully charged.

The charging curves, in wired and wireless mode (if available) show the evolution of the battery level indicator as well as the energy consumption in watts during the charging phases towards full capacity.

With the phone at different charge levels (20%, 40%, 60%, 80%), the Quick Boost tests measure how much charge the battery receives after being plugged in for 5 minutes. The graph here compares the average battery life gain with a 5 minute fast charge.

Efficiency

How the efficiency score is composed

The SBMARK Energy Efficiency Score is made up of two sub-scores, Charge Rate and Discharge Rate, both of which combine data obtained during a typical robot-based usage scenario, calibrated tests and charge rating, taking into account battery capacity of the device. SBMARK calculates the annual energy consumption of the product, shown in the graph below, which is representative of the overall efficiency during a charge and when in use.

The charging subscore is a combination of four factors: the overall efficiency of a full charge, related to the amount of energy needed to fill the battery compared to the energy 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 the phone is fully charged and still connected to the charger; and the residual consumption of the charger itself, when the smartphone is disconnected from it. The graph below shows the overall efficiency of a full charge in %.

Discharge

The discharge subscore evaluates how quickly a battery discharges during a test, which is independent of the battery’s capacity. It is the ratio between the capacity of a battery divided by its autonomy. A small capacity battery may have the same battery life as a large capacity battery, indicating that the device is well optimized, with a low discharge rate.
