Pros

  • Excellent autonomy at 3 days when used moderately
  • Very good autonomy when using the camera, watching videos or calling
  • Good charging experience, taking only 1 hour to fully charge the battery
  • Very good charge and adapter efficiency
  • Less than 1% of power lost per night

Cons

  • Higher discharge currents than average for most of the usages
  • Very high discharge currents when streaming music and gaming
  • Poor autonomy when streaming music
  • Only 91.6% of true capacity when showing 100% on the display
  • High consumption of the charger itself

The Asus ROG Phone 7 performed well in our battery test protocol and ranked in the top part of our database. Although the ROG Phone 7 behaved very much like the Asus ROG Phone 6, its scores were below its predecessor, especially in autonomy and efficiency because of higher discharge currents.

With a huge 6000mAh battery, the autonomy of the Asus ROG Phone 7 was excellent, providing three full days when used moderately. But when testing individual usages, the device struggled when listening to music. Other usages showed very good performances, especially when calling, streaming video and using the camera on-the-go, but they did not reach the autonomy of the Asus ROG Phone 6. The autonomy when gaming was also quite good, even though it, too, was slightly less than its predecessor.

The ROG Phone 7’s charging experience was good, taking only 1 hour to replenish the large battery. A quick 5-minute charge provided a decent 5 hours and 31 minutes of autonomy, which is above the average in our database.

The charge efficiencies of the device and the adapter were very good. However, the consumption of the charger itself was high and just above the average. The discharge currents were very high when streaming music and gaming, and slightly above the average for other usages, meaning that the device is not quite well optimized.

Compared with devices from the same Ultra-Premium price range ($800+), the Asus ROG Phone 7 ranked among the best devices thanks to its outstanding autonomy score for this segment. While the charging experience was average and the efficiency score was slightly above average, they both are still good for the segment.

How Autonomy score is composed

Autonomy score is composed of three performance sub-scores: Home / Office, 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.

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.

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.

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.

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 %.

Discharge

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.
