We subjected the Oppo Find N2 Flip to our rigorous SBMARK Battery test suite to measure its performance in terms of autonomy, charging and efficiency. In these test results, we’ll analyze how it performed in a variety of tests and several common use cases.
Overview
Key Specifications:
- Battery Capacity: 4300mAh
- 44W charger (included)
- 6.8 inch OLED display, 1080 x 2520, 120Hz
- MediaTek Dimension 9000+ (4nm)
- ROM / RAM combination tested: 256GB + 8GB
Pros
- Decent battery life with more than 2 days of moderate use
- Excellent autonomy during the game
- Less than 1% drop on average per night
- Low discharge current in most use cases
Against
- Low battery life on the go and during calls
- Low autonomy recovered in a quick charge of 5 minutes
- High residual power consumption of the charger when the device is fully charged and still connected
The Oppo Find N2 Flip performed well in our battery protocol tests. It ranked just below the average in our entire database, surpassing the Samsung Galaxy Flip4 for the best score among flip devices we’ve tested so far.
The Oppo Find N2 Flip’s runtime performance was decent. The 4300mAh battery lasted just over 2 days which was much better than other flip devices. The battery life while playing was quite impressive. However, the measured runtimes during calls or while traveling were poor.
The charging experience was slightly below average, and the range recovered from a 5-minute quick charge was low. The 44W charger took 1 hour and 27 minutes to fully charge the battery, while a 5-minute quick charge provided an average of just 3 hours and 23 minutes of runtime.
Also, the residual power consumption of the charger was high when the device was fully charged and still plugged in.
The charging efficiency results showed that the device was well optimized considering that the discharge currents for video streaming and gaming during our typical usage scenario were quite low. In fact, the discharge current for the game was the best measured yet.
Compared to other phones in the Ultra-Premium segment ($800+), the Oppo Find N2 Flip’s performance was in the top half of the database. Its battery life was decent, and even slightly above average. The charging experience was less than average, but its efficiency was excellent.

How the Autonomy score is composed
The Battery Life Score is composed of three performance sub-scores: Home/Office, On the Go, and Calibrated Use Cases. Each subscore includes results from a full range of tests to measure range in all kinds of real-life scenarios.

Active: 2h30/day

Home office
A robot housed in a Faraday cage performs a series of touch-based user actions during what we call our “typical usage scenario” (TUS) — making calls, streaming video, etc. — 4 hours of active use over the course of a 16 hour period, plus 8 hours of “sleep”. The robot repeats this series of actions every day until the device runs out.

Using a smartphone on the go has a negative impact on range due to additional “hidden” demands, such as continuous signaling associated with cellular network selection. SBMARK Battery experts take the phone outdoors and perform a series of precisely defined activities 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 to ours bots repeatedly perform actions related to a specific use case (like gaming, video streaming, etc.) at a time. Starting with an 80% charge, all devices are tested until they have used at least 5% battery power.

How the recharge score is composed
Charging is fully part of the overall battery experience. In some situations where range is at its lowest, knowing how fast you can charge becomes a concern. The SBMARK Battery Charging Score consists of two subscores, (1) Full Charge and (2) Fast Boost.

The full charge tests evaluate the reliability of the battery charge indicator; measure how long and how much energy it takes for the battery to charge from zero to 80% capacity, from 80 to 100% as shown by the user interface, and to an actual full charge.
The charging curves, in wired and wireless mode (if available) showing the evolution of the battery level indicator as well as the energy consumption in watts during the charging phases towards full capacity.
The time to full charge graph breaks down the time required to reach 80%, 100% and full charge.

With the phone at different charge levels (20%, 40%, 60%, 80%), the Quick Boost tests measure how much charge the battery receives after being plugged in for 5 minutes. The graph here compares the average range gain with a 5-minute quick charge.

How the efficiency score is composed
The SBMARK Energy Efficiency Score consists of two subscores, charge rate and discharge rate, which combine both data obtained during a typical robot-based usage scenario, calibrated testing and charge rating, taking into consideration battery capacity of the device. SBMARK calculates the product’s annual energy consumption, shown in the graph below, which is representative of overall efficiency during a charge and when in use.

The secondary charge score is a combination of four factors: the overall efficiency of a full charge, relating to the amount of energy required to recharge the battery compared to the energy the battery can supply; the efficiency of the travel adapter when it comes to transferring power from an outlet to your phone; the remaining consumption when the phone is fully charged and still connected to the charger; and the residual consumption of the charger itself, when the smartphone is disconnected from it. The graph below shows the overall efficiency of a full charge in %.
Discharge

The sub-discharge score evaluates how quickly a battery discharges during a test, which is independent of battery capacity. It is the ratio between the capacity of a battery and its autonomy. A small capacity battery may have the same run time as a large capacity battery, indicating that the device is well optimized, with a low discharge rate.
