Pros
- Great autonomy in moderate use
- Good autonomy when watching videos
- Low residual currents in almost all test cases
- Low residual consumption in wired and wireless charges
Cons
- Poor autonomy when gaming
- Weak autonomy when testing outdoor
- Longer than average charging time
- Low wired charge efficiency
The Apple iPhone 15 Plus achieved an excellent global battery score and ranked above its predecessor thanks to slightly better charging experience. The iPhone 15 Plus’s battery score nearly matched that of the 15 Pro Max, but it was held back by a slightly lower performance during the typical usage scenario tests.
Still, the iPhone 15 Plus showed excellent results in the typical usage scenario, with the device’s autonomy lasting 2.5 days in moderate use and losing less than 1% of power per night on average. Tests of individual indoor usage also demonstrated autonomy that was above average, especially when watching videos. However, outdoor performances were slightly below average compared with other devices from the database.
Despite a better charging experience than its predecessor, charging was overall poor, taking longer than average. The 30W charger took 2 hours to fill up the iPhone 15 Plus’s battery, and the wireless charger took 2 hours and 52 minutes. Moreover, during the boost charging test, the iPhone 15 Plus regained only 3 hours and 42 minutes of additional autonomy, which was below average.
The wireless charge efficiency was good, but the wired one was very low at only 68%, meaning that almost a third of the power drained by the charger was lost. However, the residual consumption of both wired and wireless chargers was very low whether the fully charged device was still plugged in or not. Finally, the discharge efficiency of the Apple iPhone 15 Plus was excellent thanks to low discharge currents in almost all test cases, meaning that the device was well-optimized.
Compared with devices from the Ultra-premium price range ($800+), the iPhone 15 Plus stands among the best thanks to its excellent autonomy and efficiency. However, its charging score was low for this segment.

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.

Realme GT Neo 5 (240W)

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.

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 %.

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.
