We subjected the Realme GT Neo 3 to our rigorous SBMARK battery test suite to measure its performance in terms of range, charging and efficiency. In these test results, we will analyze how it fared in a variety of tests and several common use cases.
Overview
Key specs:
- Battery capacity: 4500mAh
- 150W charger (included)
- 6.7-inch, 1080 x 2412, 120Hz OLED display
- Mediatek Dimensity 8100 (5 nm)
- ROM / RAM combination tested: 256GB + 12GB
Pros
- Exceptional charging experience reaching 80% in just 13 minutes37 and 100% in 19 minutes49
- 11 hours of autonomy gained with a quick charge of 5 minutes
- Well managed downtime and nights
Cons
- Poor performance when streaming music over 4G
- Weak performance on the go
The Realme GT Neo 3’s spectacular charging experience catapulted the device to a lower charging score, overshadowing the overall battery performance which was still quite good. Equipped with a 150W charger, the most powerful charger we’ve tested to date, the device was able to recharge its 4500mAh battery in under 20 minutes (19 min 49 seconds to be exact). The trade-off in the Realme GT Neo 3’s higher charging score, however, came in range, which was average at best when compared to the entire database, and far behind its predecessor, the Realme GT. Neo 2. One of the reasons was that the GT Neo 3’s 4500mAh battery is smaller than the GT Neo 2’s 5000mAh battery. Even the efficiency, in terms of discharge current, wasn’t handled as well as the its predecessor.
Test summary
About SBMARK Battery Tests: For the score 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 introductory article and how we test articles for more details on our Smartphone Battery Protocol.)

How the autonomy score is composed
The range score is made up of three performance sub-scores: stationary, moving, and calibrated use cases. Each sub-score includes the results of a full range of tests to measure autonomy in all kinds of real-life scenarios.

A robot housed in a Faraday cage performs a series of touch-based user actions during what we call our “typical use 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 is discharged.

Using a smartphone on the go puts a strain on autonomy due to additional “hidden” needs, such as the continuous signaling associated with the selection of the cellular network. SBMARK Battery experts take the phone outdoors and perform a well-defined set of activities 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 ours robots repeatedly perform actions related to a specific use case (such as games, video streaming, etc.) at a time. Starting at an 80% charge, all devices are tested until they have consumed at least 5% of the battery charge.
How the Charge score is composed
Charging is completely part of the overall battery experience. In some situations where battery life is minimal, knowing how fast you can charge becomes a problem. The SBMARK battery charge score consists of two secondary scores, (1) Full charge and (2) Quick boost.
Full charge tests evaluate the reliability of the battery charge indicator; measure how long and how much energy it takes the battery to charge from zero to 80% capacity, 80 to 100% as shown by the user interface, and up to an actual full charge.
Two graphs below illustrate the full charge performance of the smartphone: (1) The charging curves, in wired and wireless mode (if available) which show the evolution of the battery level indicator as well as the power consumption in watts during charging phases towards full capacity.
(2) The full charge time graph breaks down the time it takes to reach 80%, 100% and full charge.

The full charge time graph breaks down the time it takes to reach 80%, 100% and 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 graph here compares the average runtime gain from a 5 minute quick charge.

How the efficiency score is composed
The SBMARK energy efficiency score consists of two secondary scores, Charge up and Discharge rate, which combine both data obtained during a typical use scenario based on robots, calibrated tests and charge 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 charging and in use.
The secondary charge score is a combination of four factors: the overall efficiency of a full charge, relative to the amount of energy needed to fill the battery versus the energy the battery can provide; the efficiency of the travel adapter when it comes to transferring power from an outlet to the 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 secondary score 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 divided by its autonomy. 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.
