Smartphone Battery Performance Score

and Battery Results

We have designed and developed Battery Performance Labels

to help Smartphone users.

Our battery test results for the Google Pixel 7 have been translated

into the ViserMark Labels displayed below.

ViserMark Labels for the Samsung Galaxy S21

Let’s look at the ViserMark review based on the testing results.

You can find the full results of our battery performance testing below:

Smartphone Battery Performance Overall Score:

ViserMark Label for battery performance with 34/100

The Battery Performance Label shows a score between 0 and 100. It reflects the performance based on independent, repeatable, and rigorous testing.

Using various testing criteria, measured using real-life scenarios and live networks, results are collated with calculations from Battery Life, Power Efficiency and Charging results that amount to the total score.

The Google Pixel 7 was positioned in the Flagship Tier (€700+) with an attractive lower price, offering incredible value for money. With a score of 34 out of 100 obtained for battery performance, it was positioned in the bottom half of the Battery Performance Scores for 2022.

The Google Pixel 7 achieved an overall battery performance score of 34 out of 100. Therefore, it compares very well with the Samsung S22, which obtained just 2 points more with 36 out of 100.

The Sony XQ BQ52 scored 41 out of 100, slightly higher than the Samsung and Google devices, which all take positions towards the lower half of the Flagship/Pro Tier. The Apple brand remains in the top, scoring 72 and 53 out of 100, respectively, for the iPhone 13 Pro Max and iPhone 13 Pro. Both have impressive overall battery performances - those other competitors may struggle to exceed.

When evaluating the Google Pixel 7, the results were comparable with the Samsung S22. Only slight differences can be found in battery capacity and charging times, which will be discussed further in this review.

Battery Life

Battery Life - How long will this Smartphone battery last?

ViserMark Label for battery life with 1.5 Days of Use

This is expressed in “Days-of-Use” and reflects the number of days that a smartphone can be used from a full charge.

When looking at the Flagship/Pro Tier, most devices can last for 1.5 days of usage, with the exceptions being the Apple iPhone 13 Pro Max with 3.5 days of battery life and the Apple iPhone 13 Pro with one day less, with 2.5 days of battery life.

When looking at the Google Pixel range, it is clear that the battery capacity has been considerably reduced. The Google Pixel 6 was released in Oct 2021 with 4600 mAh. With the introduction of the Google Pixel 7 one year later, the battery capacity is only 4355 mAh.

Even with less battery capacity, the Google Pixel 7 can still deliver 1.5 days of use and can match smartphones within the Flagship/Pro Tier with greater battery capacity, such as the Sony XQ BQ52 with 4500mAh. However, it must be noted that the Samsung S22 also delivers 1.5 days of usage despite having an even smaller battery capacity of 3700mAh - which is quite remarkable as Flagship/Pro smartphones are expected to be feature-rich.

Google does state that Pixel’s Adaptive Battery can last over 24 hours – and up to 72 hours when you turn on Extreme Battery Saver. However, this feature disables various features, including 5G connectivity. Our battery performance protocol ensures that we measure and evaluate key areas of user experience, with all default testing performed under strictly controlled conditions without Battery Saver features enabled.

Charging Times

ViserMark Label for battery charging with 2h51

Battery Charging Time - How long will this Smartphone take to charge?

Time varies when charging different types and sizes of smartphone batteries. This is expressed in Hours and Minutes.

When reviewing Charging Times for Flagship/Pro smartphones, there is a considerable range from the fastest, only 1 hour and 13 minutes, to the slowest, the Google Pixel 7, reaching 2 hours and 51 minutes. However, the Samsung S22 also exceeded 2 hours and 36 minutes, with the Sony XQ BQ52 reaching under 2 hours to compete with smartphones at the top of the Flagship/Pro Tier.

Power Efficiency

ViserMark Label for battery efficiency with 1/5 leaves

Power Efficiency - How power efficient is this Smartphone?

Maximising the smartphone performance while reducing the energy it consumes, with minimal impact on battery life.

It is calculated using Battery Life and Battery Capacity. This is expressed in “Leaves" and reflects a rating between 1 being the least and 5 being the most power efficient.

The Google Pixel 7 scored 1, the same rating as most of the devices in the Flagship/Pro Tier, once again only exceeded by the Apple brand with higher power efficiency devices.

The most battery-efficient smartphones will provide good battery life and reduce the number of times the battery will need to be charged, harming its longevity.

Should I buy it?

The Google Pixel 7 is a reliable smartphone that delivers great camera quality, provides a good user experience and is packaged at a reasonable price for features on a higher-priced smartphone.

With face unlock technology that operates more reliably than the upgraded fingerprint scanner, this smartphone offers valuable features and improved functionality. Also, the Gorilla Glass Victus protects against scratches and accidents and being IP68-rated is an extra bonus.

The Google Pixel 7 is one of the best smartphones offered by Google, having superb software with long-term update pledges, good battery life and great stereo speakers - it's value for money.
