We put the Honor X7 through our rigorous DXOMARK Battery test suite to measure its performance in autonomy, charging and efficiency. In these test results, we will break down how it fared in a variety of tests and several common use cases.
- Battery capacity: 5000 mAh
- 22.5W charger (included)
- 6.74-inch, 720 x 1600, 90 Hz, LCD display
- Qualcomm Snapdragon 680 (6 nm)
- Tested ROM / RAM combination: 128 GB + 4 GB
Sub-scores and attributes included in the calculations of the global score.
These key points are derived from the lab measurements during testing and do not figure into the overall score. The lab measurements, however, are used for the overall score.
- Decent typical usage scenario, with excellent night management (only 1% lost on average)
- Decent autonomy in calibrated mode when gaming and calling
- Excellent performance during on-the-go tests, especially when scrolling on social apps and using GPS navigation
- Extremely low residual consumption of the charger when the device is fully charged and still plugged in
- Low discharge currents during typical usage scenario, day or night
- Whatever the use case, battery levels 8%, 28%, 48%, 68%, and 88% displayed by the UI lasted only 30 seconds
- Automatic device shut down 30 seconds after reaching 2%
- Poor performance in calibrated mode when streaming music and video
- Slow charging time due to the small 22.5W charger
- Low charge and adapter efficiency
- High discharge currents in calibrated mode, except when gaming
The Honor X7’s global battery score ranks it above average in our entire database. The autonomy was really optimized when testing in factory default settings. Indeed, it showed excellent performance during the typical usage scenario, with low discharge currents, day and night, and excellent autonomy on the go, especially when scrolling on social apps and using GPS navigation. When tested in calibrated mode, the gaming and calling tests showed decent autonomy, but the device struggled when streaming video and music. We noticed that the battery levels 8%, 28%, 48%, 68%, and 88% displayed by the UI lasted only 30 seconds, whatever the use case, even during the charging tests. When the device reached 2%, the device would automatically turn off after 30 seconds.
The 22.5W charger took its time to fill up the Honor X7’s large 5000mAh battery at 2 hours and 31 minutes to reach full capacity. The charge efficiency, as well as the adapter efficiency, was lower than the average. Even though the residual consumption of the charger itself was slightly higher than the average, its residual consumption when the device was still plugged in and fully charged was extremely low, the lowest in our database to date.
Overall, the discharge currents were low when testing in factory default settings, but above average when testing in calibrated mode (except for the gaming use case). Compared with devices from the Essential segment (under $200), the Honor’s global score was average, with average autonomy and efficiency scores. But thanks to its 22.5W charger, which is a decent power for this segment, its charging score was very good. However, because of poor performance in calibrated mode, its calibrated and discharge subscores were very low.
About DXOMARK Battery tests: For scoring and analysis in our smartphone battery reviews, DXOMARK engineers perform a variety of objective tests over a week-long period both indoors and outdoors. (See our introductory and how we test articles for more details about our smartphone Battery protocol.)

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.
Battery Life (moderate)
Battery Life (moderate)
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
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
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 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 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.
Charging Time 0-80%
Charging Time 0-80%
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.
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.
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 %.
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.
