We put the Nothing Phone (2) through our rigorous SBMARK Battery test suite to measure its performance in terms of battery life, charging and efficiency. In the results of these tests, we will analyze how it performed in a series of tests and in several common use cases.
Overview
Key Specifications:
- Battery capacity: 4700mAh
- 45W charger (not included)
- 6.7 inch OLED display, 1080 x 2412, 120 Hz
- Qualcomm Snapdragon 8+ Gen 1 (4nm)
- Tested ROM/RAM combination: 256GB + 12GB
Pros
- Excellent battery life when streaming videos
- Decent battery life with moderate use
- Good battery life when using GPS navigation and games
- Overall low discharge currents
- Excellent adapter efficiency
Against
- Poor battery life when listening to music and using the camera
- Poor battery life during idle with the screen off
- Slow wireless charging speed
The Nothing Phone (2) performed well in our battery testing protocol and ranked in the top half of our database. Its performance was very similar in terms of autonomy and efficiency compared to its predecessor, the Nothing Phone (1), but the charging experience was significantly improved thanks to the greater power supported during charging.
The autonomy of the Nothing Phone (2) with moderate use lasted 2 days and 7 hours. Testing individual uses, the battery life was slightly above average overall. Battery life is excellent when watching videos and using GPS navigation, but is poor when using the camera outdoors or listening to music.
The charging experience was good and much improved compared to its predecessor. Now supporting 45W charging, the Nothing Phone (2)’s full charge time takes just 56 minutes, half the time of its predecessor. However, wireless charging was still slow, taking 2 hours and 39 minutes to top up the battery. The autonomy recovered after a 5-minute quick charge was decent at 5 hours and 5 minutes.
Charging efficiency was decent for both wired and wireless charging, and the power adapter showed the best efficiency we’ve measured so far, but its residual power consumption was slightly higher than average. Additionally, discharge currents were low in almost all of our use cases, meaning the device is well optimized, especially when watching videos, playing games, and using GPS navigation.
When compared to devices in the High-End price range ($400 – $599), the Nothing Phone (2) ranked near the top of the database, with average battery and charging scores and a slightly above-average efficiency score for this segment.

How the autonomy score is composed
The battery life score is made up of three performance subscores: Home/Office, On the Go, and Calibrated Use Cases. Each subscore includes the results of a full range of tests to measure battery life in all types of real-life scenarios.

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 16 hours. -a period of one hour, plus 8 hours of “sleep”. The robot repeats this series of actions every day until the device runs out of power.

Using a smartphone on the move puts a strain on battery life due to additional “hidden” needs, such as the continuous signaling associated with cellular network selection. SBMARK Battery experts take the phone outdoors and perform a series of well-defined activities following the same three-hour travel itinerary (walking, taking the bus, subway…) for each device
Calibrated

For this series of tests the smartphone returns to the Faraday cage and our bots repeatedly perform actions related to a specific use case (such as gaming, video streaming, etc.) at a time. Starting from an 80% charge, all devices are tested until they have consumed at least 5% of their battery charge.

How the charging score is made up
Charging is a full part of the overall battery experience. In some situations where battery life is at its lowest, knowing how fast you can charge becomes a concern. The SBMARK Battery Charging Score is made up of two sub-scores, (1) Full Charge and (2) Quick Boost.
Full charge

Full charge tests evaluate the reliability of the battery charge indicator; measure how long and how much energy the battery takes to charge from zero to 80% capacity, from 80 to 100% as shown by the user interface, and until actually fully charged.
The charging curves, in wired and wireless mode (if available) show the evolution of the battery level indicator as well as the energy consumption in watts during the charging phases towards full capacity.

With your 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 battery life gain with a 5 minute fast charge.

How the efficiency score is composed
The SBMARK Energy Efficiency Score is composed of two sub-scores, Charge Rate and Discharge Rate, both of which combine data obtained during a typical robot-based usage scenario, calibrated tests, and charge rating, taking into account battery capacity of the device. SBMARK calculates the annual energy consumption of the product, shown in the graph below, which is representative of the overall efficiency during a charge and when in use.

The charging subscore is a combination of four factors: the overall efficiency of a full charge, related to the amount of energy needed to fill the battery compared to the energy 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 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 discharge subscore evaluates how quickly a battery discharges during a test, which is independent of the battery’s capacity. It is the ratio between the capacity of a battery divided by its autonomy. A small capacity battery may have the same battery life as a large capacity battery, indicating that the device is well optimized, with a low discharge rate.
