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. This article highlights the most important results of our testing. (See our introductory and how we test articles for more details about our smartphone Battery protocol.)

Pros
- More than 2 days of autonomy with moderate use, above average for its segment
- Well-controlled discharge current in almost all test cases
- Low residual power drain
Cons
- Low charging efficiency
- Above-average night current discharge
- When the battery indicator says 20%, the actual power remaining is less
With a maximum refresh rate of 144 Hz, the Motorola Edge 20 Pro proposes an interesting display experience — and one that does not seem to adversely affect its battery performance. We compared the Motorola Edge 20 Pro’s performance in several key categories with two other devices in our Premium segment, the Apple iPhone 13 and the Oppo Reno6 5G; battery capacity, tested charger, display type, and resolution, and processor specifications for all three devices are shown in the table below.

Autonomy (63)
How long a battery charge lasts depends not only on battery capacity but also on other aspects of the phone’s hardware and software. The DXOMARK Battery autonomy score is composed of three performance sub-scores: (1) Stationary, (2) On the go, and (3) 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.
The Motorola Edge 20 Pro just beats the Apple and Oppo devices for overall autonomy. Its battery gauge is moderately accurate: when the UI shows 20% remaining charge, the actual remaining charge is 18.4%

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.
The Motorola Edge 20 Pro lasted just slightly longer than the Apple iPhone 13 in our TUS tests, but the Motorola lost 3% power overnight vs. 1.33% for the Apple. The Oppo Reno6 Pro was two hours behind its rivals.

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 outside and perform a precisely defined set of activities while following the same three-hour travel itinerary for each device.
While the Motorola led its rivals in social apps and put in an acceptable performance for calling and camera use on the go, its disappointing performance when navigating placed it at the bottom of this pack of three.

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.
The Motorola’s performance in our calibrated tests was almost as good as that of the Reno6 Pro 5G’s, and quite far ahead of the iPhone 13’s.
Charging (78)
The DXOMARK Battery charging score is composed of two sub-scores, Full charge and Quick boost. Full charge tests assess the reliability of the battery power gauge; measure how long it takes to charge a battery from zero to 80% capacity and from 80 to 100%; and measure how long and how much power the battery takes to go from an indicated 100% to 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.

It takes the Motorola Edge 20 Pro 42 minutes to go from 0% to 80% versus 58 minutes for the iPhone13 and around only 22 minutes for the Reno6 Pro. During charging, when the Motorola’s gauge reaches 100%, it is actually only 95.4% full, whereas iPhone13 is 98.6% full when showing 100%. The Oppo gauge behaves similarly to the Motorola’s.

When charging for five minutes, the Motorola’s gain of 3 hours 30 minutes on average is better than the Apple’s, but both devices are far behind the Oppo.

Efficiency (89)
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 testing, outdoor mobility testing, charging evaluation, and power measurements, and then take into consideration the device’s battery capacity.
Though it comes in last behind the other two devices in this category overall, the Motorola nonetheless beats the Apple for charge up efficiency and the Oppo for discharge efficiency.

The Motorola’s charging efficiency is quite low — but not as low as the Apple device’s; further, its adapter is clearly the most efficient of the three.
Discharge

The Motorola device has well-controlled consumption in most use cases, especially during video streaming and 3G calling. These results are not enough to beat iPhone 13, however, which is the clear winner for discharge efficiency.
Conclusion
While not the best in the Premium segment, the Motorola Edge 20 Pro nevertheless offers a good overall experience, with more than 2 days of autonomy and a well-controlled discharge in most use cases.
