We put the Honor X9b 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: 5800mAh
- 35W charger (not included)
- 6.78-inch OLED display, 1200 x 2652, 120 Hz
- Qualcomm Snapdragon 6th generation（SM6450） (4nm)
- Tested ROM/RAM combination: 256GB + 8GB
Pros
- More than three days of battery life in case of moderate use
- Exceptional autonomy both in test cases at home/office and on the move
- Very low discharge current at night when idle
Against
- Below average charging performance, taking a long time to reach a full charge
- Discrepancy between actual battery capacity and displayed capacity. (17% measured, 20% displayed)
- 8.4% of the total capacity is actually loaded after 100% is displayed on the screen.
- Poor autonomy recovered from fast charging
The Honor X9b’s battery showed exceptional battery life and efficiency performance, placing it among the top 10 devices in our database. Equipped with a robust 5800 mAh battery, it guaranteed over three days of battery life if used moderately. Furthermore, the device showed excellent battery performance with both light and heavy usage. Light usage yielded more than four and a half days, and heavy usage garnered nearly two days of battery life. In all separate test cases, the Honor X9b showed impressive battery life, especially in video streaming, idle screen and music streaming in both Wi-Fi and 4G conditions.
Charging performance was the only area where the Honor X9b performed below average. With the 35W charger, the device took more than 2 hours to reach a full charge. Furthermore, when the phone indicated that the battery was 100% charged, in reality only 91.6% of the full charge was being drawn from the outlet.
The Honor X9b scored highly in terms of efficiency, securing a top position in our battery rankings. This was mainly attributed to the consistently low discharge current in almost all test cases. However, it is worth noting that the efficiency of the adapter, compared to other devices, seems to be relatively moderate.
Compared to other devices in the advanced segment, the Honor X9b demonstrated exceptional overall battery life and high degree of optimization which helped it secure a place in the top three positions in our battery ranking.
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. (See our introduction and how we test articles for more details on our smartphone battery protocol.)

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.

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 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.

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.
