Pros

  • Excellent autonomy during the Typical Usage Scenario, with low discharge currents, whether day or night
  • Excellent autonomy when testing in calibrated mode
  • Very good autonomy during on-the-go tests
  • Very low residual consumption of both wired and wireless chargers
  • Decent wireless charge efficiency
  • Very low discharge currents overall

Cons

  • Slow charging time, whether wired or wireless
  • Very low wired charge efficiency

The Apple iPhone 13 Pro Max reached an excellent global score, surpassing the previous top scorer, the iPhone 12 Pro Max. This significant achievement is due mainly to improved autonomy, which is attributable to the 13 Pro Max’s nearly 20% greater battery capacity, along with additional optimization.

It showed excellent performance during the Typical Usage Scenario, with only 1% lost per night on average. Outdoors, the device had a very decent autonomy, especially when using demanding GPS navigation. When testing in calibrated mode, the autonomy was above average across all our use cases.
When it came to charging, the small 20W charger struggled and it took 2 hours and 11 minutes to fill up the 4352 mAh battery. Similarly, the wireless charger took 2 hours and 41 minutes to fully charge the battery, which was longer than average. The residual consumption of both wired and wireless chargers was very low though.

The discharge currents were also very low, meaning that the device was well-optimized, whatever the use case.

Compared with devices from the same price range ($800+), the iPhone earned the top score thanks to its excellent autonomy and efficiency. However, its charging score was among the lowest.

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: Stationary, 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.

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.
