Pros
- Very fast charging
- More than 9 hours of autonomy recovered after a 5-minute charge
- Excellent charge efficiency
Cons
- Less than 2 days of autonomy in moderate use
- Low autonomy in calibrated mode, being below-average in all our use cases, especially when streaming music
- Very weak performance in on-the-go tests
- High residual consumption of the charger when the smartphone isn’t plugged in
- Higher-than-average discharge currents in all our use cases
The Poco F4 GT showed uneven performance in battery, with an excellent charging experience, but an underwhelming autonomy.
Despite a respectable 4700 mAh dual-cell battery, the device struggled in all our autonomy-related tests, especially in our on-the-go test where it ranks last of all the devices we’ve tested so far. Poco has not succeeded in taming the very performant and power-hungry Qualcomm Snapdragon 8 Gen 1 processor, leading to high discharge currents across the board, even when compared to other devices that are equipped with the same chipset.
What the Poco F4 GT lacks in autonomy, it makes up for with an outstanding charge experience. You can expect to go from an empty battery to a fully charged one in less than a half an hour. We measured a peak charging power of 113W, just shy of the advertised 120W, but sufficient enough to be among the very best in our rankings. With a very good 81% energy efficiency from the electrical outlet to the battery, the only minor stain on this otherwise excellent charging experience is the adapter’s high residual power consumption when the device is not plugged.
For a phone in the High-End segment, the Poco F4 GT manages to be close to the best in charging, but close to the weakest in autonomy and the weakest in efficiency.

Autonomy
POCO F4 GT
195
Autonomy score is composed of three performance sub-scores: Stationary, 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.

Home/Office
POCO F4 GT

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.
On the go
POCO F4 GT
195
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
Calibrated
POCO F4 GT
198
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.
Charging
POCO F4 GT
218
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
POCO F4 GT
224
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.
Quick boost
POCO F4 GT
212
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.
Efficiency
POCO F4 GT
154
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
POCO F4 GT
205
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
POCO F4 GT
194
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.
