Main specifications:
- Battery capacity: 4900mAh
- 45W charger (not included)
- 6.7-inch OLED display, 1440 x 3120, 120Hz
- Qualcomm Snapdragon 8 Gen 3 (4nm)
- Tested ROM/RAM combination: 256GB + 12GB
Pros
- Great autonomy shown when browsing social apps in outdoor conditions
- Great autonomy when watching videos and playing video games
- Very accurate battery meter, especially during wireless charging
- Low residual power consumption, regardless of whether the device is still connected or not
Against
- Poor battery life shown at idle, while making calls and listening to music
- Below-average battery life recovered with a 5-minute boost charge
- High residual power consumption of wireless media
The battery of the Samsung Galaxy S24+ (Exynos) outperformed the regular version, Samsung Galaxy S24, thanks to better battery life and charging experiences, but the overall battery score remained below the average in our database.
When used sparingly, the Samsung Galaxy S24+ (Exynos) managed to last just over two days, which is below average in our database. Uses like watching videos, playing games, and browsing social apps outdoors showed good battery life, but other use cases were below average.
The charging experience of the S24+ (Exynos) was slightly above average. The device took less than 1.5 hours to reach full charge with a wired charge. With wireless charging, the battery was fully charged in 2 hours and 20 minutes, a bit longer than other devices in our database. The battery indicator on the Galaxy S24+ (Exynos) was very accurate, regardless of whether it was charged via wire or wirelessly. When the device showed 100%, the real capacity was very close to 100%.
The device’s charging efficiency was below average for both wired and wireless charging, and the chargers’ residual consumption was good regardless of whether the device was plugged in and fully charged, with the exception of wireless support. In terms of discharge currents, the Galaxy S24+ (Exynos) showed above-average consumption, especially when listening to music and surfing outdoors, indicating that the device could be better optimized.
Compared to other ultra-premium devices ($800+), the Galaxy S24+ (Exynos) ranked in the middle of our database thanks to its good charging. However, its battery life and efficiency were below average.
Test summary
Information on SBMARK battery tests:To assign scores and analysis in our smartphone battery reviews, SBMARK engineers perform a series of objective tests over a 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 autonomy score is made up of three performance sub-scores: Home/Office, On the go and Calibrated use cases. Each sub-score includes the results of a full range of tests to measure battery life in all types of real-life scenarios.
69 hours
Light usage
Active: 2h30/day

Moderate use
Active: 4 hours per day

Heavy use
Active: 7 hours per day
Home office
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 a 16-hour period, 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 go has a negative impact on battery life due to additional “hidden” demands, such as continuous signaling associated with cellular network selection, for example. SBMARK battery experts take the phone outdoors and perform a series of precisely defined activities, following the same three-hour travel route (walking, taking the bus, subway, etc.) for each device

For this series of tests, the smartphone goes back to the Faraday cage and ours 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 composed
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; measuring 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 to a full charge.
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.

How the efficiency score is composed
The SBMARK energy efficiency score is composed of two sub-scores, Charge up and Discharge rate, both of which combine data obtained during a typical robot-based usage scenario, calibrated tests and charge evaluation, 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.
Charge Up

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 the discharge rate of a battery during a test, which is independent of the battery capacity. It is the ratio of the capacity of a battery to its runtime. A small capacity battery may have the same runtime as a large capacity battery, indicating that the device is well optimized, with a low discharge rate.
