These key points are derived from the lab measurements during testing and do not figure into the overall score. The lab measurements, however, are used for the overall score.
102nd
22nd
Pros
- Low discharge currents for indoor individual use cases
- Very low residual consumption of the wired charger
- Decent autonomy for a flip device, lasting almost two days
Cons
- Poor autonomy on the go, especially when using GPS navigation
- Weak autonomy when calling or listening to music
- Poor efficiency during the wireless charge
- Very high residual consumption of the wireless charger
- Low autonomy recovered after a quick 5-minute charge
The Samsung Galaxy Z Flip5 global battery score was below average, but it performed quite well in our battery protocol tests when compared with other “flip” devices we had tested. It outperformed the Samsung Galaxy Z Flip4 in all test cases and achieved a much better efficiency score.
The Samsung Galaxy Z Flip5’s autonomy performances were decent, with the 3700mAh battery lasting nearly 2 days. When testing individual usages, the device underperformed in our outdoor tests, particularly when using the GPS navigation, which showed very low autonomy. However, the device’s autonomy held up decently when watching videos.
The charging experience was slightly below average. The low-powered 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 autonomy on average. Residual consumption was low whether the fully charged device was still plugged in or not. Charging the device wirelessly also took longer, at an average 2 hours and 25 minutes to reach a full charge, and the residual power drain of the Samsung wireless stand itself was among the highest we have measured.
The charge efficiency was average for a wired charge, but very poor for a wireless charge. However, the efficiency was good thanks to very low discharge currents for almost all usages, indicating that the Samsung Galaxy Z Flip5 has been well optimized.
When compared to other phones in the Ultra-Premium segment ($800+), the Samsung Galaxy Z Flip5 performance was just below our database’s average. The charging experience was poor for this segment, but its autonomy was decent, even just below average, and efficiency was excellent.

Autonomy

188
Autonomy score is composed of three performance sub-scores: Home / Office, On the go, and Calibrated use cases. Each sub-score comprises the results of a comprehensive range of tests for measuring autonomy in all kinds of real-life scenarios.

Home/Office
Samsung Galaxy Z Flip5
213
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.
On the go
Samsung Galaxy Z Flip5
195
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
Calibrated

198
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.
Charging

218
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.
Full charge

224
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.

Quick boost

212
With the phone at different charge levels (20%, 40%, 60%, 80%), Quick boost tests measure the amount of charge the battery receives after being plugged in for 5 minutes. The chart here compares the average autonomy gain from a quick 5-minute charge.
Efficiency
Samsung Galaxy Z Flip5
154
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.
Charge up
Samsung Galaxy Z Flip5
205
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 %.
Discharge
Samsung Galaxy Z Flip5
194
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.
