Tested: The Pixal 6 Chagres much slower than Google implied

You’d be forgiven if you thought the Google Pixel 6 and Pixel 6 Pro had finally stepped up to fast charging. Google’s endorsement of the USB Power Delivery PPS charging protocol and the recommendation to use the latest 30W USB-C adapter for top speeds certainly suggests just as much.

But one should never jump to assumptions, and it turns out that the latest Google phones are still at the bottom of the rankings for determining shipping times. No doubt anyone who’s used the phone will frown at the “two hours max” message when hooked up. Although Google boasts a 50% charge in 30 minutes, the full cycle takes inexplicably time.

Looking closely at the literature, Google doesn’t actually mention the maximum wired charging speed for the Pixel 6 or Pixel 6 Pro phones. Here’s what the official Google Pixel 6 support page says:

You’d be forgiven if you thought the Google Pixel 6 […]

Up to 50% charge in 30 minutes with Google 30W USB-C. Charger with USB-PD 3.0 (PPS) port sold separately.
Fast wired charging rates are based on the use of a Google 30W USB-C charger plugged into a wall outlet. Compatible with USB PD 3.0 PPS adapters. Actual results may be slower. Adapters are sold separately.

Confused? Fortunately, Android Authority is working in the lab to take a closer look at the reasons for such long charging times. judgment? The supposed 30W charging is not 30W at all.

Google Pixel 6 wired charging tested

Based on our testing with Google’s official 30W USB-C adapter and a few compatible fast charging cables, we found that the maximum power obtained from both the Pixel 6 and Pixel 6 Pro is just 22W, with an average of 13W. Watt only. Course. At no point during our testing did we see speeds anywhere near the 30W charging that many (fairly) assumed the Pixel 6 series was capable of.

We corroborated these results with tests using other high-powered USB Power Delivery PPS sockets such as the Anker Nano II, Samsung 45W Travel Adapter, and Elecjet X21 Pro – all of which showed a maximum output of 22W when charging a Pixel 6, Pixel 6, or Pixel 6.

Pixel 6 phone Pro. The adapters used were all UK replacements, although our data from testing US chargers with USB PD PPS support also showed a peak charge of 22W or less on the US Pixel 6 model.

Google Pixel 6 has a charging power of 22 watts, not 30 watts.

How does this affect shipping times?

With USB Power Delivery PPS, the Google Pixel 6 Pro takes about 111 minutes to fully charge the 5,000mAh battery (about 5,000mAh typical, according to Google) from nearly empty. This number, along with all data described in this article, was obtained with adaptive charging and adaptive battery settings turned off for the Pixel 6 series phones.

All charging times listed here are based on our average numbers across multiple tests. Considering that the 4,080mAh Pixel 5 supports 18W charging and charges in around 87 minutes, that’s pretty disappointing.

Furthermore, the 22W doesn’t shy away from the Samsung Galaxy S21 Ultra’s 5,000mAh charging capabilities, which can be filled up in just over an hour with the right charger.

So why the huge discrepancy? To find out, we have to look closely at how the charge energy changes over the course of the cycle. Fast charging typically uses more power at the beginning of charging, during the DC phase of the battery, before decreasing power as the cell approaches full capacity.

Reducing power early is good for controlling temperatures and reducing battery fatigue but it comes at the cost of charging time.
