Key performances
These key points are derived from the lab measurements during testing and do not figure into the overall score. The lab measurements, however, are used for the overall score.
72nd
15th
Pros
- Very good autonomy when streaming videos
- Decent autonomy in moderate use
- Good autonomy when using GPS navigation and gaming
- Low discharge currents overall
- Excellent adapter efficiency
Cons
- Weak autonomy when listening to music and using the camera
- Poor autonomy during idle phase with screen off
- Slow wireless charging speed
The Nothing Phone (2) performed well in our battery test protocol and ranked in the top half of our database. Its performances were very similar in terms of autonomy and efficiency compared with its predecessor, the Nothing Phone (1), but the charging experience was significantly improved thanks to increased power supported during the charge.
The Nothing Phone (2)’s autonomy in moderate use lasted a decent 2 days and 7 hours. When testing individual usages, autonomy was slightly above average overall. Autonomy excelled when watching videos and using the GPS navigation, but was poor when using the camera outdoors or listening to music.
The charging experience was good and much improved over its predecessor. Now supporting charging at 45W, the Nothing Phone (2)’s time to a full charge takes only 56 minutes, half the time of its predecessor’s. However, wireless charging was still long, taking 2 hours and 39 minutes to replenish the battery. The autonomy recovered after a quick 5-minute charge was decent at 5 hours and 5 minutes.
The charge efficiency was decent for both wired and wireless charges, and the power adapter showed the best efficiency we have measured so far, yet its residual consumption was slightly higher than average. Also, discharge currents were low across almost all of our use cases, meaning that the device is well optimized, especially when watching videos, gaming and using GPS navigation,.
When compared with devices from the High-End price range ($400 – $599), the Nothing Phone (2) ranked in the upper part of the database, with average autonomy and charging scores, and an efficiency score that was slightly above average for this segment.

Autonomy
Nothing Phone (2)
195
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.

Home/Office
Nothing Phone (2)
221
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
Nothing Phone (2)
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
Nothing Phone (2)
198
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

218
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
Nothing Phone (2)
224
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
Nothing Phone (2)
212
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
Nothing Phone (2)
154
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
Nothing Phone (2)
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
Nothing Phone (2)
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.
