Key performances
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.
Pros
- Very good autonomy with more than 2.5 when used moderately
- Excellent autonomy when using the GPS on the go
- Very low residual consumption of the charger when the device is fully charged, and either plugged in or not
Cons
- Poor autonomy when listening to music
- Low autonomy gained after a quick 5-minute charge
The Samsung Galaxy A34 5G’s battery performance earned the device a global score that was above average in our database.
During the autonomy tests, the Galaxy A34 5G showed excellent results when used in factory default mode. The battery lasted more than 2.5 days during our typical usage scenario, and the autonomy on the go, especially when using the GPS, was very good. When testing specific usages, the results were not as good, but the overall autonomy remain above average. The device struggled when streaming music.
The charging time was longer than average, taking 1 hour and 42 minutes to fully charge the battery. The autonomy gained after a quick 5-minute charge was also below average with only 3 hours and 53 minutes recovered on average. Nevertheless, the charger’s residual power drain was very low when the device was fully charged and either plugged in or not.
The charge efficiency was average. The discharge currents were quite low on the go and average when testing individual usages, meaning that the device is quite well optimized.
When compared with other devices from the Advanced price segment, the Samsung Galaxy A34 5G ranked in the middle of our database, a huge improvement over its predecessor the Samsung Galaxy A33 5G, which ranked at the low end of the segment. The Galaxy A34 5G’s autonomy score was decent, but the charging and efficiency scores were slightly below the average.

Autonomy

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

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

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

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

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

184
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

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

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

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.
