We put the Honor X7b 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: 6000mAh
- 35W charger (may be included)
- 6.801-inch LCD display, 1080 x 2412, 90 Hz
- Qualcomm SDM680 (6nm)
- ROM/RAM combination tested: None GB + 8 GB
Pros
- Excellent autonomy outdoors
- The longest home/office autonomy tested so far, reaching 5 days
- Very low discharge current when the phone is active
- Low residual power consumption while the device is still connected
Against
- More than 2 hours and 30 minutes to fully charge the device
- Relatively low charging efficiency
- Little autonomy gain from a quick charge
The Honor X7b demonstrated an exceptional battery experience in our tests, achieving an overall score of 151. It outperformed its predecessor, the Honor X7a, with improved battery life and charging performance.
The Honor The device has been well optimized for each use case thanks to its very low discharge current. Its impressive endurance in every individually tested case earned the device first place in terms of battery life in our database. For example, in the home/office battery life test, the Honor X7b’s battery lasted five days, the longest recorded so far.
The Honor X7b’s 35W charger is relatively modest for a 6000mAh battery. The device took more than 2 hours and 30 minutes to fully recharge its battery, placing it in the bottom half of our database. A quick 5-minute charging boost helped the device gain more than 5 hours of battery life, a 20% improvement over its predecessor.
The charging efficiency of the Honor X7b was 74.4%, not very efficient compared to other devices tested. On the other hand, the Honor X7b’s residual power consumption was very low when the device was still connected to the charger.
Compared to other devices in the Essential segment, the Honor X7b ranked at the top. The device’s excellent battery life and well-optimized user experience have secured its place among the best in our battery rankings.
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.

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.
136 hours
Light usage
Active: 2h30/day
95 hours
Moderate use
Active: 4 hours a day
59 hours
Intense use
Active: 7 hours a day
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

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, Charge Rate and Discharge Rate, both of which combine data obtained during a typical robot-based usage scenario, calibrated tests, and charge rating, 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.
