Introduction

As the developer of Android, the Pixel series runs the native Android system with a simple interface, without too much pre-installed software and third-party customization, which is very popular among users. Users can not only directly experience the original clear operation logic of the Android system designed by Google, but also have great advantages in system updates, and can get the latest Android version updates and patches released by Google in the first place.

ChargerLAB purchased a Google Pixel 9, which is equipped with a Google Tensor G4 processor built based on Samsung's 4nm process. It has powerful performance and can better support AI functions. It has a built-in 4700mAh battery, supports 27W PD wired charging and has IP68 dust and water resistance.

Product Appearance

The front of the box is printed with a rendering of the back of the phone, and the Google logo is printed on the top.

The back is printed with information such as product configuration.

The box contains the Google Pixel 9, a dual USB-C cable, and some documents.

Google Pixel 9 is equipped with the Google Tensor G4 processor, which is Google's first processor to run Gemini Nano in multi-mode. It is built based on Samsung's 4nm process, has powerful performance, and can better support AI functions.

It has a 6.3-inch OLED screen with a resolution of 2424*1080, supports a 120Hz refresh rate, and has a peak brightness of 2700 nits. Excluding the camera in the middle, it looks like an iPhone.

It is available in four colors: Obsidian, Porcelain, Wintergreen, and Peony to meet the personalized needs of different users.

It uses a horizontal dual-camera module on the back, with a 50 MP main camera and a 48 MP ultra-wide-angle camera. The main camera uses a 1/1.31-inch Samsung GNK sensor and supports OIS optical image stabilization; the ultra-wide-angle lens is upgraded to a 50MP Sony IMX858. The front camera is a Samsung 10.5-megapixel camera.

There is a volume button and a power button on the right side.

There are no buttons on the left side.

There is a SIM card slot, USB-C port, and speaker at the bottom.

The width is about 72.06 mm (2.84 inches).

The length is about 152.87 mm (6.019 inches).

The thickness is about 8.39 mm (0.33 inches). 

The weight is about 199.2 g (7.027 oz).

That's how big it is in the hand.

The dual USB-C cable is flexible and resistant to bending.

The diameter is about 3.38 mm (0.13 inches). 

The length is about 1 m (3' 3.37'').

ChargerLAB POWER-Z KM003C shows it doesn't have an E-maker chip.

Charge with the Google 45W charger, the power is about 8.67V 2.64A 22.88W.

Wireless Charging Test

Charge with the Apple 35W charger and the new MagSafe, the input power is about 9.01V 0.56A 5.06W.

Reverse Charging Test

It can charge AirPods Pro 4 wirelessly, and the earphones light up with a red charging indicator light.

Use it to charge AirPods Pro 4 wired, and the output power on the phone is about 4.95V 0.47A 2.31W.

Compatibility Test

Next, let's do the charging compatibility test. 

Third-party Chargers

Charging with the Apple 140W charger, the power is about 17.76W, using the PD protocol.

Charging with the AOHi 140W charger, the power is about 23.68W, using the PD protocol.

Most chargers were able to trigger a 9V voltage. A small number were limited to 5V, while a few incompatible chargers delivered 0W of power.

We have compiled the test results into a bar chart. Nearly three-quarters of third-party chargers can provide it with more than 24W of power, up to 24.69W, and the rest are 17-19W. Except for the Huawei 40W charger, all other chargers can charge it.

Power Banks

The tested third-party power banks charged the Google Pixel 9 at stable power levels, generally triggering a voltage of around 9V.

We have compiled the test results into a bar chart. There are no compatibility issues. The power is distributed in two levels, 18W and 24W.

Full Charging Test

We use the Google 45W charger with the original cable to fully charge it. And put them into a 25°C (77℉) thermotank throughout the test.

The voltage is always around 9V. The charging curve can be divided into five parts. In the first part, the peak power stayed at 25W for the first 28 minutes. Then, the power dropped to 17W at 35 minutes. At 39 minutes, the power rose to 22W and then continued to drop to 11.5W. The final part begins at 57 minutes, the power slowly drops to almost zero. It takes 1 hour and 44 minutes to be fully charged.

From this chart, it can be charged to 50% in 28 minutes and 80% in 53 minutes. It reaches 100% in 1 hour and 44 minutes.

Temperature Test

We also recorded the highest temperature on the front and back after charging for 10 minutes, 20 minutes, and 30 minutes.

10 minutes Charging

After 10 minutes, the maximum temperature on the front is 31.7℃ (89.06 ℉).

The back is 31.5℃ (88.7 ℉). 

20 minutes Charging

After 20 minutes, the maximum temperature on the front is 34.9℃ (94.82 ℉).

The back is 34.9℃ (94.82 ℉). 

30 minutes Charging

After 30 minutes, the maximum temperature on the front is 36.6℃ (97.88 ℉).

The back is 36.6℃ (97.88 ℉). 

We also turn it into another curve. The temperature during charging is between 31.7-36.6℃. The temperature keeps rising during the charging process. The maximum temperature reached 36.6℃ at 30 minutes, and the power was about 23W. The charging power is not high and the temperature control is average.

Summary of ChargerLAB

Google Pixel 9 is equipped with a Tensor G4 processor, a 6.3-inch 120Hz OLED screen, a 50-megapixel main camera, a 48-megapixel ultra-wide-angle camera, 12GB of storage, a 4700mAh battery, supports 27W wired charging, and has AI functions. It is equipped with Android 14, and Google promises to provide up to 7 years of system support for the Pixel 9 series.

It takes 1 hour and 44 minutes to be fully charged. Nearly three-quarters of third-party chargers can provide it with more than 24W of power, up to 24.69W, and the rest are 17-19W. Overall, the Google Pixel 9 has significantly improved its appearance, screen, image, performance, and other configurations compared to the Pixel 8 series.
