Pros
- Decent autonomy when streaming video and calling, with low discharge currents
- Good autonomy when scrolling on social apps on-the-go (device folded)
- Excellent charger efficiency
- Low residual consumption of the charger
Cons
- 3.33% lost per night on average
- Poor autonomy when gaming and streaming music
- Poor autonomy when using GPS navigation and camera
- Long charging time, whether wired or wireless
- Poor autonomy recovered after a 5-minute charge
- Low charge efficiency
- High residual consumption of the wireless charger itself
The Samsung Galaxy Z Fold4’s battery performance was at the low end of our global ranking, which is usually the case for devices in our Ultra-premium segment. However, the Z Fold4 showed battery performance improvements in all our subscores over its predecessor the Z Fold3 5G.
In moderate use, the Z Fold4’s autonomy was better than the Z Fold3 5G. When testing some use cases separately, such as calling and video streaming, the Z Fold4 showed decent autonomy and low discharge currents, meaning that the device has been well-optimized for such usage. However, when the device was tested outside and unfolded to take to photos and videos, the battery drained very quickly. The autonomy when using GPS navigation was low, too.
The small 25W charger kept the charging pace slow, and a 5-minute charge only provided 2 hours and 36 minutes of autonomy. In addition, the charge efficiency was low. However, the residual consumption of the charger was well-managed. Wireless charging wasn’t any better and showed very high residual consumption.
Compared with other Ultra-premium devices in our database, the Z Fold4’s autonomy was slightly above average, which is decent for a foldable phone.
Test Summary
About DXOMARK Battery tests: For scoring and analysis in our smartphone battery reviews, DXOMARK engineers perform a variety of objective tests over a week-long period both indoors and outdoors. DXOMARK’s Battery performance protocol was designed based on the classic one-screen smartphone design. However, the multiple ways of using certain apps and features on foldables required the Battery team to adapt the protocol and test certain use cases with the phone folded or unfolded, depending on what the most likely usage would be. See our introductory and how we test articles for more details about our smartphone Battery protocol.
The following section gathers key elements of our exhaustive tests and analyses performed in DXOMARK laboratories. Detailed performance evaluations under the form of reports are available upon request. Do not hesitate to contact us.

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.

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

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.

How Charging score is composed
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.
105
Realme GT Neo 5 (240W)
Realme GT Neo 5 (240W)
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.

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.

How Efficiency score is composed
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.

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 %.

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.
