We put the Nokia G42 5G through our rigorous SBMARK Battery test suite to measure its performance in terms of battery life, charging and efficiency. In the results of these tests, we will analyze how it performed in a series of tests and in several common use cases.
Overview
Key Specifications:
- Battery capacity: 5000mAh
- 20W charger (not included)
- 6.56-inch LCD display, 720 x 1612, 90 Hz
- Qualcomm Snapdragon 480+ 5G (8nm)
- Tested ROM/RAM combination: 128GB + 6GB
Pros
- Good overall battery life with over 2.5 days of battery life
- Battery life on the move is very good, especially on calls
- Excellent low residual charger consumption
Against
- Long 2 hours and 45 minutes to fully charge the battery
- Less than 2 hours of battery life recovered after a 5 minute quick charge
- Very poor charging efficiency
The Nokia G42 5G’s overall battery score ranked the device slightly below the average for the entire database.
The Nokia G42 5G’s battery lasted 2.5 days when the device was used moderately. Battery life during individual usage tests was average overall, but the 4G and mobility test cases showed decent battery life.
The charging experience is a drawback of the Nokia G42 5G. With a low-power 20W charger, it took 2 hours and 45 minutes to fully recharge the battery, which is about double the database average. Additionally, a 5-minute quick charge provides just under 2 hours of additional battery life on average.
The battery efficiency score was brought down by the charging efficiency, which is one of the lowest we’ve ever measured, despite the adapter efficiency being average. This means that the device struggles to efficiently store the energy loaded into the battery. However, the usage efficiency of the device was more than decent with low discharge currents in the 4G and mobility test cases, which means that the device has been optimized for this usage.
Compared to other devices in the Advanced price segment ($200 to $399), the Nokia G42 5G’s performance was slightly below average in terms of battery life and below average in terms of efficiency. The charging experience, however, was poor and almost borderline for this price range.
Test summary
Information on SBMARK battery tests: For scoring and analysis in our smartphone battery reviews, SBMARK engineers perform a series of objective tests over a period of one week both indoors and outdoors. (See our introduction and how we test articles for more details on our smartphone battery protocol.)

How the autonomy score is composed
The battery life score is made up of three performance subscores: Home/Office, On the Go, and Calibrated Use Cases. Each subscore includes the results of a full range of tests to measure battery life in all types of real-life scenarios.

Light usage
Active: 2h30/day

Active: 4 hours a 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 the course of 16 hours. -a period of one hour, 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 move puts a strain on battery life due to additional “hidden” needs, such as the continuous signaling associated with cellular network selection. SBMARK Battery experts take the phone outdoors and perform a series of well-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 consumed at least 5% of their battery charge.

How the charging score is made up
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
80

Full charge tests evaluate the reliability of the battery charge indicator; measure how long and how much energy the battery takes to charge from zero to 80% capacity, from 80 to 100% as shown by the user interface, and until actually fully charged.
The charging curves, in wired and wireless mode (if available) show the evolution of the battery level indicator as well as 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 robot-based usage scenario, calibrated tests and charging evaluation, taking into account 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 how quickly a battery discharges during a test, which is independent of the battery’s capacity. It is the ratio between the capacity of a battery divided by its autonomy. A small capacity battery may have the same battery life as a large capacity battery, indicating that the device is well optimized, with a low discharge rate.
