42nd
Pros
- Decent autonomy when calling in calibrated mode
- Good autonomy when calling and using camera on-the-go
- Very low residual consumption of the charger, as well as the wireless charger
Cons
- Poor autonomy during typical usage scenario
- Inaccurate battery gauge
- Extremely low autonomy when streaming videos in calibrated mode
- Low autonomy when gaming and streaming music in calibrated mode
- Very low autonomy when scrolling social apps on-the-go
- Long charging time
- Low autonomy gained after a 5-minute charge
- Low charge efficiency
- Very high discharge current when streaming videos and music, gaming, and scrolling on social apps
The Sony Xperia 1 IV showed poor autonomy when tested in default settings during the typical usage scenario tests. Its performance on-the-go was decent when calling or taking photos and videos, but when it came to scrolling on social apps, the autonomy fell drastically to one of the lowest levels we have measured to date. When tested in calibrated mode, the Sony Xperia 1 IV had decent autonomy in the calling test as well, but it struggled a lot when streaming videos, where it had one of the lowest autonomy readings in our database. The gaming and music streaming use cases came with poor autonomy, too.
On the charging side, the Xperia 1 IV didn’t show a great performance either. The 30W took 2 hours to fill up the large 5000 mAh battery, and only provided 2 hours and 40 minutes of autonomy after a 5-minute charge. The wireless experience was average, taking 2 hours and 18 minutes to fully charge the device.
The charge efficiency was poor, but the residual consumptions of both wired and wireless chargers were low, consuming a very small amount of power.
Discharge efficiency was also poor, with the Sony Xperia 1 IV draining very high discharge currents during use cases like gaming, music streaming, GPS navigation, and especially video streaming, showing that it is not well-optimized for such usage. The camera and call use cases, however, were well managed, which was evident by the low current drainage.
When compared with devices from the Ultra-premium segment ($800+), the Sony Xperia 1 IV gets a very low score as well. The autonomy is close to average, but the charging and efficiency scores were very low.

Autonomy

188
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.

Home/Office

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

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

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

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

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
Sony Xperia 1 IV
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

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

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.
