Pros
- Excellent performance during the typical usage scenario
- Well-managed idle phases
- Excellent autonomy when streaming videos and calling when in calibrated mode
- Very good autonomy when scrolling on social apps and taking photos and videos on the go
- Very low discharge current in almost all use cases
Cons
- Average charging experience for its class, taking 44 minutes to reach 80%
The Oppo Reno 8 Lite 5G battery provided an excellent performance in autonomy, charging and efficiency, placing it among the top three devices in our protocol ranking. In the typical usage scenario, the Oppo’s results were impressive, whether during active or idle phases, such as at night, where it lost only 1.33% on average per night. When tested in calibrated mode, its autonomy was above average in all our use cases, especially when calling and streaming videos. The autonomy during our on-the-go tests was good, too, particularly when scrolling on social apps and taking photos and videos.
Regarding the charging performance, the 33W travel adapter offered an average charging time and provided more than 5h of autonomy after plugging it in for 5 minutes. The charge efficiency, as well as the adapter efficiency, was average.The discharge currents were very low, whatever the use case, which gave the Oppo an excellent efficiency, showing that the device is well-managed.
Compared with High-end devices ($400 to $599), the Oppo had one of the best autonomy and efficiency performances, but its charging performance was below average, held back by the low 33W charger. This price segment, on average, usually features 65W chargers, nearly double the power.

Autonomy

Autonomy score is composed of three performance sub-scores: Stationary, 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.
On the go

195
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
Calibrated

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.
Charging

181
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

184
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.

Quick boost

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.
Efficiency

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

205
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

194
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.
