Pros
- Excellent autonomy in all our test cases, especially video and gaming
- Good charging experience for such a massive battery
Cons
- Inaccurate battery power display: when 15.8% of autonomy is left, UI displays 20%
We recently tested the Honor X9c battery, whose performance earned it a top score in our database at the time of publication.
Equipped with a serious 6600 mAh battery, the Honor X9c exhibited an impressive battery life of just over three and half four days under moderate usage.
The device gained 12 hours of autonomy over the previous model, the Honor X9b, lasting close to 89 hours without needing to recharge. Across most test cases, particularly in video streaming and gaming, the Honor X9c demonstrated exceptional autonomy, also achieving the No. 1 spot in our autonomy sub-score.
Charging performance was also robust, despite the massive capacity to charge, thanks to the 66W charger. The Honor X9c reached 80% of a full charge in about 42 minutes, and recovered almost 7 hours of autonomy in a quick 5-minute battery top up, surpassing its predecessor X9b. Despite those impressive charging times, the X9c was still behind the charging time of the Oppo Find X7 Ultra, which achieved 80% of a full charge in half the time (20 minutes) on a 100W charger.
The Honor X9c also ranked high in our efficiency subscore, thanks to its consistently low discharging current across nearly all individual test cases, especially video streaming and gaming. The efficiency of a full charge was however just average, and we measured relatively high residual power drains from the grid after the end of a full charge.
Compared to other devices in the Advanced segment, the Honor X9c showcased exceptional overall battery life and a high degree of optimization, surpassing its predecessor and becoming our new top score globally, and of course, in its segment.

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.

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.

How Charging score is composed
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.
114
Realme GT Neo 5 (240W)

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.

How Efficiency score is composed
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.
