We subjected the Samsung Galaxy S23+ (Snapdragon) to our rigorous SBMARK Battery test suite to measure its performance in terms of battery life, charging and efficiency. In these test results, we’ll analyze how it performed in a variety of tests and several common use cases.
Overview
Key Specifications:
- Battery Capacity: 4700mAh
- 45W charger (not included)
- 6.6 inch OLED display, 1080 x 2340, 120Hz
- Qualcomm Snapdragon 8 Gen2 (4nm)
- ROM / RAM combination tested: 256GB + 8GB
Pros
- Excellent autonomy when watching videos
- Low residual power consumption when the device is fully charged and still plugged in
- Low overall discharge currents
Against
- Low battery life when listening to music
- High residual consumption of the wireless support
- Low wireless charging efficiency
The battery of the Samsung Galaxy S23+ scored well overall, placing it in the top half of our database.
The Galaxy S23+ achieved 61 hours of battery life when used moderately. When testing individual uses indoors and out, performance was also very good when watching videos or using social apps. However, battery performance was poor when listening to music or using the camera.
The charging experience was average overall, both wired and wireless. However, the autonomy recovered after just 5 minutes of charging was slightly above average.
The device’s efficiency when charging via cable was average, but poor when using the wireless charger. The discharge currents were low in all individual uses (except when listening to music and when using the camera), which means the device is well optimized.
When compared to other devices in the Ultra-Premium price range ($800+), the Samsung Galaxy S23+ performed very well, supported by its excellent battery life and efficiency scores in this segment. The charging experience was good, but only slightly above average for the segment.

How the Autonomy score is composed
The Battery Life Score is composed of three performance sub-scores: Home/Office, On the Go, and Calibrated Use Cases. Each subscore includes results from a full range of tests to measure range in all kinds of real-life scenarios.

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 the course of a 16 hour period, plus 8 hours of “sleep”. The robot repeats this series of actions every day until the device runs out.

Using a smartphone on the go has a negative impact on range due to additional “hidden” demands, such as continuous signaling associated with cellular network selection. SBMARK Battery experts take the phone outdoors and perform a series of precisely defined activities 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 to ours bots repeatedly perform actions related to a specific use case (like gaming, video streaming, etc.) at a time. Starting with an 80% charge, all devices are tested until they have used at least 5% battery power.

How the recharge score is composed
Charging is fully part of the overall battery experience. In some situations where range is at its lowest, knowing how fast you can charge becomes a concern. The SBMARK Battery Charging Score consists of two subscores, (1) Full Charge and (2) Fast Boost.

The full charge tests evaluate the reliability of the battery charge indicator; measure how long and how much energy it takes for the battery to charge from zero to 80% capacity, from 80 to 100% as shown by the user interface, and to an actual full charge.
The charging curves, in wired and wireless mode (if available) showing 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 range gain with a 5-minute quick charge.

How the efficiency score is composed
The SBMARK Energy Efficiency Score consists of two subscores, charge rate and discharge rate, which combine both data obtained during a typical robot-based usage scenario, calibrated testing and charge rating, taking into consideration battery capacity of the device. SBMARK calculates the product’s annual energy consumption, shown in the graph below, which is representative of overall efficiency during a charge and when in use.

The secondary charge score is a combination of four factors: the overall efficiency of a full charge, relating to the amount of energy required to recharge the battery compared to the energy the battery can supply; the efficiency of the travel adapter when it comes to transferring power from an outlet to your phone; the remaining 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 sub-discharge score evaluates how quickly a battery discharges during a test, which is independent of battery capacity. It is the ratio between the capacity of a battery and its autonomy. A small capacity battery may have the same run time as a large capacity battery, indicating that the device is well optimized, with a low discharge rate.
