Pros
- Good charging experience
- Excellent wireless charging performance
Cons
- Very high consumption for 4G music streaming and gaming
- Below-average performance in autonomy tests
OnePlus 9 Pro’s overall score suggests an average performance for a device in its price range; however, it owes a lot to its very fast charging time. Among its segment competitors in this review, it lags considerably behind the Apple iPhone 13 Pro Max in terms of autonomy and efficiency, and a bit behind the Samsung Galaxy S21 Ultra (Snapdragon) in terms of autonomy.
Battery capacity, tested charger, display type and resolution, and processor specifications for all three devices are shown in the table below.

*Note that while the OnePlus 9 Pro and the Samsung Galaxy S21 Ultra 5G (Snapdragon) are equipped with QHD display screens, their default UI resolution is FHD only (1080 x 2412 for the OnePlus and 1080 x 2400 for the Samsung).
Autonomy (46)
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.

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 OnePlus 9 Pro put in a disappointing performance in our Typical Usage Scenario tests, offering only 44 hours of autonomy. However, the OnePlus lost only 2% of its charge at night; while that puts it behind the iPhone 13 Pro Max (1% lost), it’s better than the S21 Ultra (Snapdragon), which lost on average 3.67% at night.

Best: Samsung Galaxy M51 (96)
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.
The OnePlus 9 Pro did better in our on the go tests, but still came in behind the other two devices in all categories except for camera, where it beat the Samsung. Nevertheless, its results are below-average in terms of all Ultra-Premium devices in our database.

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.
Here again, the OnePlus 9 Pro came in behind its Apple and Samsung competitors, especially when gaming and streaming music via 4G.

Charging (99)
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.
The OnePlus 9 Pro comes with a 65W charger which allows it to significantly outperform both the Apple iPhone 13 Pro Max and the Samsung Galaxy S21 Ultra (Snapdragon) with their respective 20W and 25W chargers.

The OnePlus 9 Pro takes 53 minutes to fully charge its battery, versus 2 hours 9 minutes for the iPhone 13 Pro Max and 1 hour 27 minutes for the S21 Ultra Snapdragon.
Among the three devices, OnePlus 9 Pro is the fastest for wireless charging, taking 1 hour 10 minutes versus 2 hours 41 minutes for the Apple and 2 hours 27 minutes for the Samsung.
