Pros

  • Excellent autonomy in indoor use cases
  • Low discharge currents in general
  • More than 7 and a half hours of autonomy regained from a 5-minute charging boost
  • Full charge completed in just over 53 minutes

Cons

  • Slightly below-average autonomy in outdoor use cases
  • Overall charge efficiency of less than 75%
  • High residual power drain from the adapter while the device is still plugged in

Oppo Reno12 battery earned high marks for its very balanced and impressive performance in autonomy, charging, and efficiency, signifying a well-optimized system.

The device’s autonomy lasted for more than 70 hours under moderate usage. The device remained strong in indoor testing, losing only around 1% of power per night. In specific use-case testing, the device’s autonomy was above average, except when listening to music. The autonomy of the device was generally great when on the go, except when calling, which showed below-average autonomy.

The Oppo Reno12 is equipped with a 5000 mAh battery and comes with an 80W charger, which fully charges the device in 53 minutes, faster than average. The powerful charger also helped the device regain more than seven and a half hours of autonomy on average from a 5-minute charging boost.

Efficiency was also above average thanks to its discharge efficiency. The device’s overall charge efficiency of a full charge was less than 75%, which signified that more than a quarter of the energy was wasted during the charging process. However, the Reno12’s discharge currents were below average, except when listening to music and when the device was idle with the screen off.

Compared to other devices in the High-end segment ($400 to $599), the Oppo Reno12 ranked among the best devices, thanks to its very balanced battery performances.

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.

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.
