We subjected the Google Pixel 7 to our rigorous SBMARK Battery test suite to measure its performance in terms of battery life, charging and efficiency. In this summary of results, we’ll analyze how it performed in a variety of tests and several common use cases.
Overview
Key Specifications:
- Battery Capacity: 4355mAh
- 30W charger (not included)
- 6.3-inch OLED display, 1080 x 2400, 90Hz
- Google Tensor G2 (5 nm)
- ROM / RAM combination tested: 128GB + 8GB
Pros
- The charger has low residual consumption whether the device is plugged in and fully charged or unplugged
- Decent battery life while gaming
Versus
- Low autonomy during calls during calibrated tests and on the go
- High power consumption when streaming music
- Low gain in autonomy with a 5 minute recharge
- Very long wireless charging time (3 hours and 46 minutes)
Despite a slightly smaller battery capacity and similar behavior, the Google Pixel 7 scored higher overall than the Pixel 6, thanks to improved efficiency. However, its overall battery life is below average when compared to other devices in the high-end segment ($400-599).
When testing each usage separately, the device still showed high power consumption both at home and on the road, but offered decent performance while gaming. While the device can use a 30W charger (not included), the Pixel 7’s wired charging was poor, as was wireless charging. Also, a five-minute charge provided less than 3 hours of additional battery life, which is low compared to other phones.

How the Autonomy score is composed
The Battery Life Score is composed of three performance sub-scores: Home/Office, On the Go, and Calibrated Use Cases. Each subscore includes results from a full range of tests to measure range in all kinds of real-life scenarios.

A robot housed in a Faraday cage performs a series of touch-based user actions during what we call our “typical usage scenario” (TUS) — making calls, streaming video, etc. — 4 hours of active use over the course of a 16 hour period, plus 8 hours of “sleep”. The robot repeats this series of actions every day until the device runs out.

Using a smartphone on the go has a negative impact on range due to additional “hidden” demands, such as continuous signaling associated with cellular network selection. SBMARK Battery experts take the phone outdoors and perform a series of precisely defined activities 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 to ours bots repeatedly perform actions related to a specific use case (like gaming, video streaming, etc.) at a time. Starting with an 80% charge, all devices are tested until they have used at least 5% battery power.

How the recharge score is composed
Charging is fully part of the overall battery experience. In some situations where range is at its lowest, knowing how fast you can charge becomes a concern. The SBMARK Battery Charging Score consists of two subscores, (1) Full Charge and (2) Fast Boost.

The full charge tests evaluate the reliability of the battery charge indicator; measure how long and how much energy it takes for the battery to charge from zero to 80% capacity, from 80 to 100% as shown by the user interface, and to an actual full charge.
The charging curves, in wired and wireless mode (if available) showing the evolution of the battery level indicator as well as the energy consumption in watts during the charging phases towards full capacity.

With the phone at different charge levels (20%, 40%, 60%, 80%), the Quick Boost tests measure how much charge the battery receives after being plugged in for 5 minutes. The graph here compares the average range gain with a 5-minute quick charge.

How the efficiency score is composed
The SBMARK Energy Efficiency Score consists of two subscores, charge rate and discharge rate, which combine both data obtained during a typical robot-based usage scenario, calibrated testing and charge rating, taking into consideration battery capacity of the device. SBMARK calculates the product’s annual energy consumption, shown in the graph below, which is representative of overall efficiency during a charge and when in use.

The secondary charge score is a combination of four factors: the overall efficiency of a full charge, relating to the amount of energy required to recharge the battery compared to the energy the battery can supply; the efficiency of the travel adapter when it comes to transferring power from an outlet to your phone; the remaining consumption when the phone is fully charged and still connected to the charger; and the residual consumption of the charger itself, when the smartphone is disconnected from it. The graph below shows the overall efficiency of a full charge in %.

The sub-discharge score evaluates how quickly a battery discharges during a test, which is independent of battery capacity. It is the ratio between the capacity of a battery and its autonomy. A small capacity battery may have the same run time as a large capacity battery, indicating that the device is well optimized, with a low discharge rate.
