Pros

  • Low discharge currents overall
  • Low residual consumption for both wired and wireless charges

Cons

  • Below-average autonomy in almost all calibrated tests
  • Very low autonomy when gaming
  • Longer than average charging times

The Apple iPhone 15 Pro showed very similar behavior to the iPhone 14 Pro, but its battery experience was slightly below that of its predecessor and quite average when compared to other devices we have tested.

The iPhone 15 Pro’s autonomy lasted a bit more than two days when it was used moderately, a decent result even if below average in our database. However, the device’s performance was less optimal when testing individual use cases, especially when gaming and listening to music, where the autonomy was poor.
In terms of charging experience, the iPhone 15 Pro took 1 hour and 56 minutes to fully charge with a 30W charger, which was longer than average.

The wireless charging time was also longer than average at 2 hours and 41 minutes. Moreover, the additional autonomy gained after a 5-minute charge was 3 hours and 17 minutes on average, which was lower than average in our database. The wireless charge efficiency was decent, but the wired charge efficiency was a bit low. However, the residual consumption of both wired and wireless chargers was well-controlled, with very low power drained. Finally, the strength of the device was its good discharge efficiency, providing low discharge currents for the majority of the use cases, meaning that the device was well-optimized.

Compared to the other devices in the Ultra-Premium segment, the battery experience of the iPhone 15 Pro was just above the average. Its efficiency score was very good for the segment, and the autonomy was decent, while the charging efficiency was slightly below average.

Test Summary

About DXOMARK Battery tests: For scoring and analysis in our smartphone battery reviews, DXOMARK engineers perform a variety of objective tests over a week-long period both indoors and outdoors. (See our introductory and how we test articles for more details about our smartphone Battery protocol.)

How Autonomy score is composed

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.

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.

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.

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.

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.

Charge up

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

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.
