DisplayWe put the Google Pixel 7 through our rigorous DXOMARK Battery test suite to measure its performance in autonomy, charging and efficiency. In this results summary, we will break down how it fared in a variety of tests and several common use cases.
Overview
Key specifications:
- Battery capacity: 4355 mAh
- 30W charger (not included)
- 6.3-inch, 1080 x 2400, 90 Hz OLED display
- Google Tensor G2 (5 nm)
- Tested ROM / RAM combination: 128 GB + 8 GB
Scoring
Sub-scores and attributes included in the calculations of the global score.

Key performances
These key points are derived from the lab measurements during testing and do not figure into the overall score. The lab measurements, however, are used for the overall score.
115th
22nd
Pros
- Charger has low residual consumption whether device is plugged in and fully charged or is unplugged
- Decent autonomy when gaming
Cons
- Low autonomy when calling during calibrated and on-the-go tests
- High consumption when streaming music
- Low gain in autonomy with a 5-minute charge
- Very long wireless charging time (3 hours 46 minutes)
Despite a slightly smaller battery capacity and similar behavior, the Google Pixel 7 achieved a higher global score than the Pixel 6, thanks to improved efficiency. However, its overall autonomy is below average when compared with other devices in the High-end ($400-599) segment.
When testing each individual usage separately, the device still showed high consumption whether at home or on the go, but it put in a decent performance when gaming. Even though the device can use a 30W charger (not included), the Pixel 7’s wired charging was poor, as was its wireless charging. Moreover, a five-minute charge provided less than 3 hours of additional autonomy, which is low compared to other phones.
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.)

Autonomy
Google Pixel 7
188
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.

Home/Office
Google Pixel 7

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
Google Pixel 7
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
Google Pixel 7
198
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
Google Pixel 7
181
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
Google Pixel 7
184
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

182
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
Google Pixel 7
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
Google Pixel 7
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
Google Pixel 7
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.
