89th
18th
Pros
- Decent autonomy for a foldable phone when used moderately
- Good autonomy when streaming videos (device unfolded)
- Low residual consumption of the wired charger
- Low discharge currents for streaming videos, gaming and scrolling on social apps
Cons
- Poor autonomy when listening to music
- Poor autonomy when using the camera (device unfolded)
- Long wireless charging time at 2 hours and 49 minutes
- Low wireless charge efficiency
- High residual consumption of the wireless stand
The Samsung Galaxy Z Fold5’s battery performance achieved the best score to date among the foldable devices we have tested so far, even though its score was just below average in our global ranking. The Z Fold5 showed improvements in battery performance compared with its predecessor the Z Fold4, in all subscores, especially in autonomy and efficiency.
In moderate use, the Samsung Galaxy Z Fold5’s battery lasted around 2 days and 6 hours, a result just below average but better than other foldable devices. The Z Fold5 showed good performances when testing use cases unfolded. Discharge currents were low, and autonomy was good when streaming videos and decent when gaming, but also when scrolling social apps (tested folded). Therefore, the device has been well optimized for such screen-on use cases. The autonomy was poor and the discharge currents were high when streaming music, calling and using the camera.
The low-powered 25W charger slowed the charging pace, taking the battery 1 hour and 44 minutes to reach a full charge, while a 5-minute charge provided only 3 hours and 43 minutes of autonomy. Wireless charging was also longer than average, at 2 hours and 49 minutes to fully charge the battery. Moreover, the residual consumption of the wireless stand was among the highest we’ve seen, but the residual power drain by the wired charger was excellent whether the fully charged device was still plugged in or not. Thus, the efficiency was average for wired charging but weak for the wireless one.
Compared with other Ultra-Premium devices, the Samsung Galaxy Z Fold5’s autonomy and efficiency were above average, which is very good for a foldable phone. However, its charging experience was poor for this segment.

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 Fold5
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 Fold5
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

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 Fold5
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 Fold5
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 Fold5
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.
