Pros

  • Good autonomy overall with over 2.5 days of battery life
  • Very good autonomy in mobility, especially while calling
  • Excellent low residual consumption of the charger

Cons

  • Long 2 hours 45 minutes to fully charge the battery
  • Less than 2 hours of battery life recovered after a 5-minute quick charge
  • Very poor charge efficiency

The Nokia G42 5G’s global battery score ranked the device slightly below average in the entire database.

The Nokia G42 5G’s battery lasted 2.5 days when the device was used moderately.  Autonomy when testing individual usages was average overall, but 4G and mobility test cases showed decent autonomy.

The charging experience is a drawback of the  Nokia G42 5G. With a low-powered 20W charger,  it took 2 hours and 45 minutes to fully replenish the battery, which is about double the average of  the database. In addition, a quick 5-minute charge provided slightly less than 2 hours on average of additional autonomy.

The battery’s efficiency score was dragged down by its charge 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 loaded energy in its battery. Yet, the device usage efficiency was more than decent with low discharge currents in 4G and mobility test cases, which means that the device has been optimized for this usage.

Compared with other devices from its Advanced price segment ($200 to $399), the Nokia G42 5G performance was slightly below average for autonomy, and below average of efficiency. The charging experience, however, was poor, and near the bottom for this price range.

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. (See our introductory and how we test articles for more details about our smartphone Battery protocol.)

How Autonomy score is composed

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.

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.

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.

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

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.
