We put the Honor X9c 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: 6600mAh
- 66W charger (not included)
- 6.78-inch OLED display, 1224 x 2700, 120 Hz
- Qualcomm Snapdragon 6 Gen1 (SM6450) (4nm)
- Tested ROM/RAM combination: 256GB + 8GB
Pro
- Excellent battery life in all our test cases, especially videos and games
- Good charging experience for such a powerful battery
Against
- Inaccurate battery charge display: When 15.8% battery life remains, the UI displays 20%
We recently tested the Honor X9c’s battery, whose performance earned it the top score in our database at the time of publication.
Equipped with a 6600mAh battery, the Honor X9c showed an impressive battery life of just over three and a half days with moderate usage.
The device gained 12 hours of battery life compared to the previous model, the Honor X9b, lasting almost 89 hours without needing to be recharged. In most test cases, particularly in video streaming and gaming, the Honor X9c demonstrated exceptional battery life, even taking first place in our battery life subscore.
Charging performance was also robust, despite the huge charging capacity, thanks to the 66W charger. The Honor a fast battery charge of 5 minutes, surpassing its predecessor X9b. Despite these impressive charging times, the X9c still fell behind the Oppo Find X7 Ultra, which achieved 80% of a full charge in half the time (20 minutes) on a 100W charger.
The Honor X9c also ranked high in our efficiency subscore, thanks to its consistently low discharge current in almost every single test case, especially video streaming and gaming. The efficiency of a full charge was only average, however, and we measured relatively high residual power consumption from the grid after the end of a full charge.
Compared to other devices in the Advanced segment, the Honor X9c showed exceptional overall battery life and a high degree of optimization, surpassing its predecessor and becoming our new top score globally and, of course, in its segment.
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.

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.
128 hours
Light usage
Active: 2h30/day
89h
Moderate use
Active: 4 hours a day
55 hours
Intense use
Active: 7 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

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.
Charge Up

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.
