We put the Honor 70 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: 4800 mAh
- 66W charger (included)
- 6.67-inch, 1080 x 2400, 120 Hz, OLED display
- Qualcomm Snapdragon 778G Plus (6 nm)
- Tested ROM / RAM combination: 256 GB + 8 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 autonomy in a typical usage scenario
- Good autonomy when gaming and streaming videos in calibrated mode
- Decent autonomy on-the-go, especially when scrolling on social apps
- Decent charging experience
- Excellent charge and adapter efficiency
- Low discharge currents
- Automatic device shutdown 30 seconds after reaching 2%
- Above-average residual consumption of the charger
The Honor 70 showed a decent autonomy experience. Its performance during the Typical Usage Scenario (TUS) was above average, with good night management (only 1.67% of power lost per night). The experience was above average also during the on-the-go tests, especially when scrolling on social apps and using the camera. In calibrated mode, the performances were satisfactory across all use cases, with decent autonomy when gaming and streaming videos.
When it came to charging, the 66W charger provided about 6 hours and 30 minutes of autonomy after a 5-minute boost. It took 31 minutes and 40 seconds to fill the battery to 80% of its 4800 mAh capacity, and 1 hour and 13 minutes to fully charge it. We also measured that the time between the 100% displayed on the screen and the true full charge, which is indicated by a drop of power consumption from the outlet, was really long at 28 min. In addition, the residual consumption of the charger was higher than average. The charge efficiency, as well as the power adapter efficiency, was good.
Focusing on the discharge efficiency, we saw that the Honor 70 had low discharge currents during the TUS, especially during active phases (screen on), meaning that the device is well-optimized when testing in factory default settings. The discharge currents were low too when testing in calibrated mode, especially for the video streaming and gaming tests.
Compared with devices from the same price range ($400 to $599), the Honor gets a decent global score thanks to its autonomy performance, but its charging and efficiency scores are just average.
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.
