Pros
- Outstanding autonomy in home/office test cases
- Great autonomy in outdoor tests
- Very low discharging currents in most of the individual test cases
Cons
- Almost 2 hours required to fully replenish the battery
- Overall charge efficiency below average
We recently tested the Honor Magic6 Lite (5800 mAh) battery, whose performance placed it among the top devices in our database. Considering that the Magic6 Lite (5800 mAh) is a renamed version of the Honor X9b for different regions, we put the Honor X9b through a sanity check. We observed considerable improvements compared to the results of our first evaluation run in the fall of 2023. We have therefore updated the test results with the latest scores.
Equipped with a robust 5800 mAh battery, the Honor X9b exhibited an impressive battery life of over three days under moderate usage. The device gained more than 3 hours of autonomy over the previous test, lasting 80 hours and 31 minutes without having to recharge. Across various test cases, particularly in video streaming, idle screen-on, and music streaming under both Wi-Fi and 4G conditions, the Honor X9b demonstrated exceptional autonomy. Even in outdoor conditions, the device showcased remarkable battery performance, especially during camera usage.
Charging performance was the only area where the Honor X9b fell slightly below average. Despite the 35W charger, the device took nearly 2 hours to achieve a full recharge. In the 5-minute boost charging test, the Honor X9b showed an improvement by regaining 5 hours and 40 minutes of autonomy, which was 1 hour and 30 minutes more than before, placing the device slightly above average in this aspect.
The Honor X9b excelled in efficiency tests, earning a notable position in our battery ranking. This success can be largely attributed to its consistently low discharging current across nearly all individual test cases. However, the device’s overall charge efficiency of 74.8% was below average when considering the energy ratio between the battery capacity and the amount of energy grabbed from the power grid. It’s worth noting, though, that the adapter efficiency, measured at 90.9%, appeared to be relatively moderate when compared to other devices
Compared to other devices in the Advanced segment, the Honor X9b showcased exceptional overall battery life and a high degree of optimization, securing a position at the top of its segment for now.

Autonomy
Honor X9b
195
Autonomy score is composed of three performance sub-scores: Home / Office, 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
Honor X9b
221
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
Honor X9b
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
Honor X9b
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
Honor X9b
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
Honor X9b
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
Honor X9b
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
Honor X9b
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
Honor X9b
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
Honor X9b
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.
