The Oppo Reno6 5G turned in a stellar battery performance, taking top marks in certain categories and coming in first globally among all devices in our database as of this writing. The device is well balanced overall and provides a good comprehensive experience.
We compared the Oppo Reno6 5G’s performance in several key categories with two other devices in our High-end segment, the Realme GT 5G and the Samsung Galaxy A52 5G; battery capacity, tested charger, display type and resolution, and processor specifications for the three devices are shown in the table below.
| Oppo Reno6 5G | Realme GT 5G | Samsung Galaxy A52 5G | |
| Battery capacity (mAh) | 4300 | 4500 | 4500 |
| Charger | 65W | 65W | 15W |
| Display type | OLED | OLED | OLED |
| Display resolution | 2400 x 1080 | 2400 x 1080 | 2400 x 1080 |
| Chipset | MediaTek Dimensity 900 | Snapdragon 888 5G | Snapdragon 750G 5G |
Autonomy (73)
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.
Leading its segment for overall autonomy, the Oppo Reno6 5G provides 57 hours of autonomy with moderate use, which is five hours more than Realme GT 5G and one hour more than the Samsung Galaxy A52 5G.

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.
Garnering the top score for this sub-attribute in the High-end segment, the Oppo Reno6 5G lasted roughly 10 hours more than its competitors in our TUS tests. However, it lost some 2% of its battery charge at night, which is similar to the Realme GT 5G’s performance, but behind the Samsung Galaxy A52 5G at 1.33%.

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.
On the go testing proved to be the only category in which the Oppo Reno6 5G fell below our database average, coming in 6 points behind the Realme GT and 12 points behind Samsung Galaxy A52 5G. The Reno6 did well for social apps, staying just ahead of its rivals, but in all other areas, it is behind (and sometimes far behind) both the Realme and Samsung devices.

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.
With the exception of 3G calling, where it lags about 6 hours behind the Realme and Samsung, the Reno6 put in a decent performance in our calibrated tests.
Charging (109)
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 Oppo Reno6 5G is currently in the top slot for charging in our Battery protocol database, 7 points ahead of the Realme GT 5G and more than 40 points ahead of the Samsung Galaxy A52 5G.

The Oppo Reno6 5G and the Realme GT 5G both come with 65W chargers, which certainly helps reduce the time they take to reach a full charge. The Samsung Galaxy A52 5G comes with only a 15W charger for filling its 4500 mAh battery and thus ends up far behind the other two devices.

Another top performance from the Oppo Reno6 5G, whose 10-hour gain in quick-boost autonomy is better than the Realme’s at all stages (20%, 40%, 60%, 80%) and far ahead of the Samsung’s.

Efficiency (101)
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.
The Oppo Reno6 5G earned a first-place score for overall Efficiency both in its segment and across the entire Battery protocol database to date.
Charge up

The Oppo Reno6 5G has the best charge-up efficiency in its segment — around 1% more efficient than the Realme GT 5G and 9% more than the Samsung Galaxy A52 5G. However, the Oppo’s residual power drain is above average, so users should unplug the charger from the electrical outlet when done charging.
Discharge

Despite having the smallest battery among the three devices in this comparison, the Oppo’s low daytime current discharge contributes to a good performance during TUS testing. In calibrated tests, its mean current discharge of 161 mA bests the Realme (199 mA) and just edges out the Samsung (165 mA).
OppoReno has a low discharge current in almost all tests except for 3G calling, where it has the highest discharge among the three devices here.
Conclusion
Despite coming in behind its rivals when used for phone calls, the Oppo Reno6 5G is a very well-balanced and well-designed device that shows good autonomy and outstanding results for charging and charge-up efficiency.
