We subjected the Samsung Galaxy Z Flip5 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 number of tests and in several common use cases.
Overview
Key Specifications:
- Battery Capacity: 3700mAh
- 25W charger (not included)
- 6.7-inch, 1080 x 2640, 120Hz OLED display
- Qualcomm Snapdragon 8 Gen 2 (4nm)
- ROM/RAM combination tested: 256GB + 8GB
Pros
- Low discharge currents for individual indoor use cases
- Very low residual consumption of the wired charger
- Fair autonomy for a flip device, lasting almost two days
Against
- Poor range on the move, especially when using GPS navigation
- Poor battery life when making calls or listening to music
- Poor efficiency during wireless charging
- Very high residual consumption of the wireless charger
- Low autonomy recovered after a quick charge of 5 minutes
The Samsung Galaxy Z Flip5’s overall battery score was below average, but it performed quite well in our battery protocol tests compared to other “flip” devices we’d tested. It outperformed the Samsung Galaxy Z Flip4 in all test cases and scored a much better efficiency score.
The battery life performance of the Samsung Galaxy Z Flip5 was decent, with the 3700mAh battery lasting almost 2 days. When testing individual usages, the device underperformed in our outdoor tests, particularly when using GPS navigation, which showed very low battery life. However, the battery life of the device held up decently when watching videos.
The charging experience was a little below average. The low-power 25W charger took 1 hour and 35 minutes to fully charge the battery, while a quick 5-minute charge boost provided only 3 hours of runtime on average. Residual consumption was low whether the fully charged device was still plugged in or not. Charging the device wirelessly also took longer, averaging 2 hours and 25 minutes to reach a full charge, and the residual power consumption of the Samsung wireless stand itself was among the highest we’ve measured.
Charging efficiency was average for wired charging, but very poor for wireless charging. However, the efficiency was good due to very low discharge currents for almost all usages, indicating that the Samsung Galaxy Z Flip5 has been well optimized.
Compared to other phones in the Ultra-Premium segment ($800+), the performance of the Samsung Galaxy Z Flip5 was just below the average in our database. The charging experience was poor for this segment, but the autonomy was decent, even just below average, and the efficiency was excellent.

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 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 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.

The use of the smartphone on the go puts a strain on autonomy due to additional “hidden” needs, such as the continuous signaling associated with the selection of the cellular network. 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, the subway…) for each device

For this series of tests, the smartphone returns to the Faraday cage and to our 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 a full 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 Recharge Score is made up of two subscores, (1) Full Charge and (2) Quick Boost.

The full charge tests evaluate the reliability of the battery charge indicator; measure how much time 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 until 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 range gain with a 5-minute quick charge.

How the efficiency score is composed
The SBMARK Energy Efficiency Score is composed of two sub-scores, charging speed and discharge speed, both of which combine 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, related to the amount of energy required to fill 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 of the capacity of a battery divided by 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.
