We subjected the Samsung Galaxy A35 5G to our rigorous SBMARK Battery test suite to measure its performance in terms of battery life, charging and efficiency. In these test results, we’ll break down how it performed in a variety of tests and several common use cases.
Overview
Main specifications:
- Battery capacity: 5000mAh
- 25W charger (not included)
- 6.6-inch OLED display, 1080 x 2340, 120 Hz
- Samsung Exynos 1380 (5nm)
- Tested ROM/RAM combination: 128GB + 6GB
Pros
- Great autonomy during gaming and when idle
- Great autonomy on the move while using navigation and playing music
- Low residual power consumption when the device is unplugged
Against
- High discharge currents in general
- Poor battery life outdoors when browsing social apps and making calls
- Less than 3 hours of battery life gained with a 5-minute charging boost
The Samsung Galaxy A35 5G struggled in most of our battery tests, especially when it came to battery life, and failed to outperform its predecessor, the Galaxy A34 5G.
When used moderately, the Samsung Galaxy A35 5G delivered just over two days of battery life, which is below average in our database. However, the device’s battery life was noteworthy when browsing outdoors, and battery life was particularly strong when gaming and idling. However, for other indoor usage scenarios, battery life was average. Additionally, battery life was relatively poor when listening to music, browsing social apps, and making calls on the go.
With a 25W wired charger, the battery charging time was longer than average, taking more than 1.5 hours to fully recharge. Limited by the maximum charging power, a 5-minute quick charge provides less than 3 hours of battery life, which is a bit low compared to other devices.
Even with the high efficiency of the adapter and the low residual power of the wired charger itself, the efficiency score of the A35 5G was brought down by the overall high discharge currents and low charging efficiency.
Compared to other devices in the Advanced segment ($200 – $399), the Samsung Galaxy A35 5G’s performance in terms of battery life, efficiency, and charging experience remained poor and below average.

How is the autonomy score composed?
The battery life score is composed of three performance sub-scores: Home/Office, On the go, and Calibrated use cases. Each sub-score includes the results of a comprehensive set of tests to measure battery life in all types of real-life scenarios.

Active: 2h30/day

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 a 16-hour period, plus 8 hours of “sleep.” The robot repeats this series of actions every day until the device runs out of power.

Using a smartphone on the go has a negative impact on battery life due to additional “hidden” demands, such as continuous signaling associated with cellular network selection, for example. SBMARK battery experts take the phone outdoors and perform a series of precisely defined activities, following the same three-hour travel itinerary (walking, taking the bus, subway…) for each device

For this series of tests the smartphone returns to the Faraday cage and our bots repeatedly perform actions related to a specific use case (such as gaming, video streaming, etc.) at a time. Starting from an 80% charge, all devices are tested until they have used up at least 5% of their battery.

How the charging score is composed
Charging is a full part of the overall battery experience. In some situations where battery life is at its lowest, knowing how fast you can charge becomes a concern. The SBMARK Battery Charging Score is made up of two sub-scores, (1) Full Charge and (2) Quick Boost.

Full-charge tests evaluate the reliability of the battery charge indicator; they measure how long 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, until it reaches an actual full charge.
The charging curves, wired and wireless (if available), show the evolution of the battery level indicator and the energy consumption in watts during the charging phases towards full capacity.
The time to full charge table breaks down the time needed to reach 80%, 100% and full charge.

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 battery life gain with a 5 minute fast charge.

How the efficiency score is composed
The SBMARK Energy Efficiency Score is composed of two sub-scores, charging speed and discharging speed, which combine both data obtained during a typical usage scenario based on robots, calibrated tests and charging evaluation, taking into account the battery capacity of the device. SBMARK calculates the annual energy consumption of the product, shown in the graph below, which is representative of the overall efficiency during a charge and when in use.

The charging subscore is a combination of four factors: the overall efficiency of a full charge, related to the amount of energy needed to fill the battery compared to the energy 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 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 discharge subscore evaluates the discharge rate of a battery during a test, which is independent of the battery capacity. It is the ratio of the capacity of a battery to its runtime. A small capacity battery may have the same runtime as a large capacity battery, indicating that the device is well optimized, with a low discharge rate.
