We subjected the POCO F4 GT to our rigorous SBMARK battery test suite to measure its performance in terms of range, charge 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: 4700mAh
- 120W charger (included)
- 6.67-inch, 1080 x 2400, 120Hz OLED display
- Qualcomm Snapdragon 8 Gen 1 (4 nm)
- ROM / RAM combination tested: 128GB + 8GB
Pros
- Very fast charging
- More than 9 hours of autonomy recovered after a 5 minute charge
- Excellent charging efficiency
versus
- Less than 2 days of autonomy with moderate use
- Low battery life in calibrated mode, resulting below average in all of our use cases, especially when streaming music
- Very weak performance in tests on the go
- High residual consumption of the charger when the smartphone is not connected
- Above-average discharge currents in all of our use cases
The Poco F4 GT showed erratic performance on battery, with an excellent charging experience, but a disappointing range.
Despite a respectable 4700mAh dual-cell battery, the device struggled in all of our range-related tests, especially in our on-the-go test where it is the last of all the devices we have tested so far. Little failed to tame the highly performing and energy-hungry Qualcomm Snapdragon 8 Gen 1 processor, leading to high discharge currents across the board, even when compared to other devices equipped with the same chipset.
What the Poco F4 GT lacks in terms of range, it makes up for with an exceptional charging experience. You can expect to go from a dead battery to a fully charged one in less than half an hour. We measured a peak charging power of 113W, just under the advertised 120W, but enough to be among the best in our ranking. With a very good 81% energy efficiency from electrical outlet to battery, the only small blemish on this otherwise excellent charging experience is the adapter’s high residual power consumption when the device is not plugged in.
For a phone in the High-End segment, the Poco F4 GT manages to be close to the best in terms of charging, but close to the weakest in autonomy and the weakest in efficiency.
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.

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
110

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.
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 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.
