We subjected the Asus ROG Phone 7 to our rigorous SBMARK Battery test suite to measure its performance in terms of battery life, charging and efficiency. In these test results, we’ll analyze how it performed in a variety of tests and several common use cases.
Overview
Key Specifications:
- Battery Capacity: 6000mAh
- 65W charger (included)
- 6.78-inch, 1080 x 2448, 165Hz OLED display
- Qualcomm Snapdragon 8 Gen2 (4nm)
- ROM / RAM combination tested: 256GB + 12GB
Pros
- Excellent autonomy at 3 days if used moderately
- Very good autonomy when using the camera, watching videos or making calls
- Good charging experience, taking only 1 hour to fully charge the battery
- Great charging and adapter efficiency
- Less than 1% energy loss per night
Against
- Above-average discharge currents for most uses
- Very high discharge currents when streaming music and games
- Poor battery life when streaming music
- Only 91.6% of real capacity when showing 100% on display
- High consumption of the charger itself
The Asus ROG Phone 7 performed well in our battery test protocol and ranked at the top of our database. While the ROG Phone 7 performed very similarly to the Asus ROG Phone 6, its scores lagged behind its predecessor, especially in terms of runtime and efficiency due to higher discharge currents.”
With a huge 6000mAh battery, the runtime of the Asus ROG Phone 7 was excellent, providing a full three days when used moderately. But when testing individual uses, the device struggled when listening to music. Other uses showed very good performance, especially during calls, video streaming and using the camera on the go, but it didn’t match the battery life of the Asus ROG Phone 6. Battery life while gaming was also quite good , although, too, it was slightly inferior to its predecessor.
The ROG Phone 7 charging experience was good, taking just 1 hour to top up the large battery. A 5-minute quick charge provided a decent runtime of 5 hours and 31 minutes, which is above average in our database.
The charging efficiency of the device and the adapter was very good. However, the consumption of the charger itself was high and just above average. Discharge currents were very high when streaming music and gaming, and slightly above average for other uses, meaning the device isn’t optimized well enough.
Compared to devices in the same Ultra-Premium price range ($800+), the Asus ROG Phone 7 ranked among the best devices thanks to its outstanding battery life score for this segment. While the charging experience was average and the efficiency score slightly above average, both are still good for the segment.

How the Autonomy score is composed
The Battery Life Score is composed of three performance sub-scores: Home/Office, On the Go, and Calibrated Use Cases. Each subscore includes results from a full range of tests to measure range in all kinds of real-life scenarios.

Home office
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 a 16 hour period, plus 8 hours of “sleep”. The robot repeats this series of actions every day until the device runs out.

Using a smartphone on the go has a negative impact on range due to additional “hidden” demands, such as continuous signaling associated with cellular network selection. SBMARK Battery experts take the phone outdoors and perform a series of precisely defined activities 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 to ours bots repeatedly perform actions related to a specific use case (like gaming, video streaming, etc.) at a time. Starting with an 80% charge, all devices are tested until they have used at least 5% battery power.

How the recharge score is composed
Charging is fully part of the overall battery experience. In some situations where range is at its lowest, knowing how fast you can charge becomes a concern. The SBMARK Battery Charging Score consists of two subscores, (1) Full Charge and (2) Fast Boost.

The full charge tests evaluate the reliability of the battery charge indicator; measure how long and how much energy it takes for the battery to charge from zero to 80% capacity, from 80 to 100% as shown by the user interface, and to an actual full charge.
The charging curves, in wired and wireless mode (if available) showing 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 graph breaks down the time required 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 range gain with a 5-minute quick charge.

How the efficiency score is composed
The SBMARK Energy Efficiency Score consists of two subscores, charge rate and discharge rate, which combine both data obtained during a typical robot-based usage scenario, calibrated testing and charge rating, taking into consideration battery capacity of the device. SBMARK calculates the product’s annual energy consumption, shown in the graph below, which is representative of overall efficiency during a charge and when in use.

The secondary charge score is a combination of four factors: the overall efficiency of a full charge, relating to the amount of energy required to recharge the battery compared to the energy the battery can supply; the efficiency of the travel adapter when it comes to transferring power from an outlet to your phone; the remaining 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 sub-discharge score evaluates how quickly a battery discharges during a test, which is independent of battery capacity. It is the ratio between the capacity of a battery and its autonomy. A small capacity battery may have the same run time as a large capacity battery, indicating that the device is well optimized, with a low discharge rate.
