Pros

  • Excellent indoor autonomy
  • Low discharging currents in all use cases
  • More than 7 hours of autonomy regained from a 5-minute charging boost

Cons

  • Below-average overall charging efficiency
  • High residual power drain from the adapter while the device is still plugged in
  • Below-average autonomy when calling outdoors

The Oppo Reno12 Pro’s very good battery result was supported by its balanced and great performances in autonomy, charging, and efficiency, which showed that the device’s power system was well-optimized.

In autonomy, the Oppo Reno12 Pro endured almost 71 hours of moderate usage. Tests showed that power loss was only 1% during the night while the phone was idle.  In most use cases, the autonomy of the device was above average in general, except for listening to music. However, the device was just average in on-the-go testing, especially when calling. Calling autonomy tumbled to less than 22 hours in outdoor conditions from more than 35 hours in indoor tests.

The Oppo Reno12 Pro is equipped with a 5000 mAh battery and comes with an 80W charger that allows the device to reach a full charge in just over an hour. Thanks to the powerful charger, the Reno12 Pro regained more than seven hours of autonomy from a 5-minute charging boost.

The efficiency score of Oppo Reno12 Pro was above average in general, held back by the charge-up efficiency despite a better showing in discharge efficiency. The overall charge efficiency of the device was 73.2%, which indicates that more than a quarter of the energy was wasted during the charging process. However, below-average discharge currents mean that the device manages its power in a very efficient way.

Compared to other devices in the High-end ($400-$599) segment, Oppo Reno12 Pro ranked No.1, thanks to its great and balanced battery performance.

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.

Charge up

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.
