Pros
- Good autonomy in both indoor and outdoor tests
- Low discharge currents in almost all the test cases
- Good wireless charge efficiency
- Low residual consumptions in both wired and wireless charges
Cons
- Poor autonomy during gaming
- Longer-than-average charging times
- Low wired charge efficiency
The Apple iPhone 15 Pro Max’s battery experience was excellent in autonomy and efficiency, ranking the device in the top half of the entire database.
The iPhone 15 Pro Max demonstrated great performance in the autonomy tests, whether indoor or outdoor tests. With a moderate user profile, the device lasted more than 69 hours, ranking it among the best devices in our database. Under individual test cases, the iPhone 15 Pro Max also showed above-average autonomy in almost all the test cases, except for gaming, which consumed power more than average.
The charging experience with the 30W charger was still relatively weak when compared with other smartphones. We measured a maximum charging speed of 27W. It took the iPhone 15 Pro Max more than 2 hours to arrive at a full charge, ranking the device in the middle of our database. In the quick charge boost test, the iPhone 15 Pro Max regained only 4 hours and 5 minutes of additional autonomy, which was average.
The iPhone 15 Pro Max showed impressive efficiency thanks to the relatively low discharging currents for almost all the individual test cases, indicating that the device is generally well-optimized. On the other hand, the wired charge efficiency of the iPhone 15 Pro Max was quite poor, with a loss of almost a third of the power drained by the charger. Despite that, the residual consumptions of both chargers were very low whether the fully charged device was still plugged in or not.
Compared to other devices in the Ultra-premium segment ($800+), the iPhone 15 Pro Max ranked near the top of our database. The well-optimized device demonstrated a very competitive autonomy, regardless of the small capacity of the battery. The only main drawback was the weak charging experience.

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.

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.
