We subjected the Honor X8 5G to our rigorous SBMARK battery test suite to measure its performance in terms of range, charging 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: 5000mAh
- 22.5W charger (included)
- 6.52-inch, 720 x 1600, 90Hz LCD display
- Qualcomm Snapdragon 480+ 5G (8 nm)
- Tested ROM / RAM combination: 128GB + 6GB
Pros
- Exceptional typical usage scenario
- Excellent range during our on-the-go tests
- Fair autonomy if tested in calibrated mode
- Low residual battery charger consumption when the device is fully charged and still connected
- Discharge currents below average
versus
- Battery levels of 8%, 28%, 48%, 68% and 88% remain on the display for only 30 seconds, regardless of use case
- Automatic device shutdown 30 seconds after reaching 2%
- Slow charging time thanks to the small 22.5 W charger
- Low charging efficiency
The battery of the Honor X8 5G provided exceptional runtimes when tested in factory default mode. The device held a charge for more than 3 full days during the typical use scenario (TUS), one of the best performance we’ve seen so far. We had the same excellent experience when testing on the go, especially when scrolling through social apps. In calibrated mode, the device showed decent performance in all of our use cases as well.
When it came to charging, the small 22.5W charger took 2 hours and 12 minutes to fill the large 5000mAh battery. A 5-minute charge provided only 4 hours of battery life, which is less than the average in our database.
The time it takes for the battery to reach a true full charge, measured when the power consumption from the outlet decreases, after the device displays 100% on the screen was a very long 41 minutes. But at the end of the charge, the residual consumption of the charger was very low. By measuring the amount of energy needed to fill the battery from the power outlet, we noticed that the charging efficiency was below average.
Focusing on discharge efficiency, we saw that the Honor X8 5G had very low discharge currents during the TUS (day and night) and our on-the-go tests, which means that the device was well managed with factory defaults . Discharge currents were also low during the calibrated mode test, with the exception of the video streaming test, where it was average.
Compared to devices in the same price range ($ 200 to $ 399), the Honor X8 5G scored a decent overall score thanks to its runtime performance, but its charging and efficiency scores were below average.
Test summary
Information on 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. (See our introductory article and how we test articles for more details on our Smartphone Battery Protocol.)

How the autonomy score is composed
The autonomy score is made up of three sub-scores of performance: Home / Office, On the go, 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 while following the same three-hour travel itinerary (on foot, by bus, by 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 autonomy 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) Fast 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, 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.
